description: Quantity estimation is one of the important stages in construction project planning because it affects material requirements and project execution in the field. One method commonly used to determine work quantities is Quantity Take-Off (QTO), which is carried out based on project construction drawings. This study aims to analyze the Quantity Take-Off results for pile cap and tie beam works based on the construction drawings of School X Project in Medan City. A descriptive quantitative method was employed using structural drawings and reinforcement details as the primary data sources. The research stages included structural element identification, calculation of concrete volume, reinforcement requirements, and formwork area for each element under review. The results showed that the total concrete requirement for pile cap and tie beam works was 258.096 m³, the reinforcement requirement was 24,735.317 kg, and the formwork requirement was 1,009.117 m². These findings indicate that accurate quantity estimation is essential to ensure proper material planning and to minimize the risk of material shortages or excesses during project execution. The results of this study can be used as a basis for material planning and quantity control, thereby supporting a more effective and well-organized construction process. In addition, this study may serve as a reference for the implementation of Quantity Take-Off in substructure works with similar characteristics.

Tinjauan Literatur Pengaruh pH dan Suhu Terhadap Korosi Baja dan Anti-Fouling Kapal
type: item
description: Indonesia’s maritime sector relies heavily on ships with steel-hulled structures that are susceptible to corrosion due to interaction with seawater. This corrosion rate is significantly accelerated by microenvironmental factors such as temperature fluctuations and acidity levels (pH). This qualitative study employs a literature review method to analyze secondary data from 15 reputable scientific journals published between 2021 and 2026. The results of the study show that acidic conditions (pH < 7) and rising seawater temperatures have been proven to simultaneously accelerate the corrosion rate of steel ship hull materials. As a primary protective solution, antifouling paint technology functions effectively as a dual physical barrier to break direct contact between the metal and the electrolyte while preventing the attachment of marine microorganisms. Based on a comparative matrix, spray-applied polyurethane demonstrated the most optimal protective efficiency on steel, with the lowest average corrosion rate of 2.5402 × 10?? mmpy. In addition, the use of natural materials such as sweet orange peels and kepok banana peels has great potential as environmentally friendly coating alternatives, with average corrosion rates ranging from 0.010 to 0.045 mmpy. Although the application of these coatings faces challenges such as high costs and weather-related factors, optimizing these protective coatings is crucial for improving ship operational efficiency.

Studi Literatur Karakteristik Fisik dan Mekanik Aspal Modifikasi Berdasarkan Hasil Uji Laboratorium (Periode 2020–2025)
type: item
description: Conventional asphalt still has limitations in withstanding increasing traffic loads and environmental influences, which can lead to permanent deformation, cracking, and a reduction in pavement service life. Various studies have developed modified asphalt to improve pavement performance; however, the findings remain scattered and have not been comprehensively synthesized. This study aims to examine the physical and mechanical characteristics of modified asphalt based on laboratory testing results using the Systematic Literature Review (SLR) method. Data were collected from Google Scholar, ScienceDirect, SpringerLink, ResearchGate, and SINTA-indexed national journals published between 2020 and 2025. The initial search yielded 85 articles, and after applying the inclusion and exclusion criteria, 11 articles were selected for analysis. The reviewed data included binder physical characteristics, rheological properties, and the mechanical characteristics of asphalt mixtures. The results indicate that the use of modification materials such as polymers, rubber, nanomaterials, and plastic waste generally improves the softening point, Marshall stability, and resistance to permanent deformation. However, the increased stiffness observed in some modified asphalt types may reduce mixture flexibility and increase the risk of cracking at low temperatures. Therefore, modified asphalt has significant potential to enhance pavement performance, but the selection of modification materials and their dosage should be adjusted to technical requirements to achieve optimal performance.

type: item
description: The construction sector is one of the industries with a relatively high risk of occupational accidents due to complex work activities, the use of heavy equipment, and dynamic working environments. These conditions make the implementation of Occupational Safety and Health (OSH) essential to protect workers from occupational accidents and health problems. This study was conducted to evaluate the implementation of OSH and identify potential work accident risks in construction projects in Medan City. A descriptive qualitative method was applied through field observations, documentation, and an OSH checklist. The results indicate that OSH implementation at the project site has generally been carried out well, as reflected by the availability of Personal Protective Equipment (PPE), safety signs, fire extinguishers, and evacuation routes. However, several unsafe conditions were still identified, including incomplete use of PPE, work at heights without adequate protection, and dusty working environments. These conditions may increase the risk of occupational accidents and health problems among workers. Therefore, improved supervision, worker awareness, and environmental control are needed to optimize OSH implementation and create a safer workplace.

type: item
description: Sugar production in Indonesia is still fluctuating and has not been able to meet the increasing domestic demand, so a comprehensive analysis of factors related to sugar production and accurate forecasting methods is needed. This study aims to analyze the relationship between sugarcane production and yield to sugar production in Indonesia and compare the accuracy of multiple linear regression forecasting methods and Single Exponential Smoothing (SES). The data used is secondary data obtained from the Central Statistics Agency with a total of 44 observations. The analysis was carried out using linear regression to test the relationship between variables and the SES method to forecast until 2025. The results showed that sugarcane production and yield had a significant relationship with sugar production, both partially and simultaneously, with a determination coefficient value (R²) of 0.703. The accuracy test showed that the linear regression method had a MAPE value of 11.75%, while the SES method was 8.85%, so the SES was considered more accurate. The forecast results indicate a trend to increase sugar production until 2025. Thus, the SES method is more suitable for forecasting, while linear regression is more appropriate for analyzing the relationships between variables.

Rule-Based Reasoning Penentuan Pola Asuh Anak Berbasis Aplikasi Android
type: item
description: Parenting style plays a crucial role in shaping children’s character and behavior. However, limited access to relevant knowledge often prevents parents from recognizing the type of parenting they practice. To address this issue, this study developed an Android-based application for determining parenting styles using the Scrum software development framework. The parenting style classification system was built by applying the Rule-Based Reasoning (RBR) method, which processed Pengguna questionnaire inputs into IF–THEN logical rules based on two primary psychological dimensions: control and warmth. The rules and assessment indicators were derived from expert knowledge obtained from Gantari Psychology Clinic. Based on the scores of these two dimensions, the system classified parenting styles into four categories: Authoritative (Democratic), Authoritarian, Permissive, and Neglectful. In addition, the application provided personalized parenting recommendations tailored to the child’s age (0–60 months) and the dominant parenting style identified. Functional testing of the system used the Black Box Testing method indicated that all core features operate effectively and in accordance with the system design. This application was expected to serve as a practical self-learning tool for parents to evaluate and improve their parenting practices, thereby supporting optimal child development.

Pemanfaatan Limbah Plastik Polyethylene Terephthalate (PET) Sebagai Agregat Kasar Beton Ringan: Systematic Literature Review
type: item
description: Plastic waste, particularly polyethylene terephthalate (PET) from beverage bottles, constitutes a major source of non-biodegradable waste that is difficult to decompose and poses long-term environmental risks. The utilization of polyethylene terephthalate (PET) waste as a partial replacement for coarse aggregate in concrete offers a dual benefit: reducing plastic waste while conserving natural aggregates and decreasing concrete density for lightweight applications.This study systematically examines the mechanical properties of polyethylene terephthalate (PET)-based concrete through a systematic literature review following the PRISMA 2020 protocol, covering publications from 2018 to 2026. A literature search was conducted across the SINTA, Portal Garuda, Google Scholar, and Scopus databases, yielding 155 initial articles. After a rigorous screening process, 7 experimental studies met the inclusion criteria, namely those that utilized polyethylene terephthalate (PET) as a coarse aggregate substitute and reported quantitative data on compressive strength and/or density. The synthesis reveals a consistent trend in which increasing polyethylene terephthalate (PET) content reduces compressive strength (ranging from 13–20 MPa at 5–10% substitution and 7–10 MPa at >25%) as well as density (1,645–1,900 kg/m³), resulting in lightweight non-structural concrete. A combination of PET and rice husk ash achieved an optimal compressive strength of 24.85 MPa. Substitution levels of 5–10% are most suitable for semi-structural elements, whereas levels above 25% are optimal for non-structural applications such as partition panels and precast drainage channels.

Optimalisasi Kinerja Saluran Drainase Studi Kasus Daerah Kelurahan Petisah Hulu, Medan Melalui Evaluasi Teknis
type: item
description: This study aims to assess the effectiveness of the drainage system in the urban area of Petisah Hulu Village in reducing the risk of flooding caused by high rainfall and rapid land use changes. Hydrological analysis was conducted using the Log Pearson Type III distribution to calculate the design rainfall, while the existing channel capacity was analyzed using the rational method. Based on the technical evaluation in the Final Report of the Medan Urban Drainage Plan (MUDP) Open Channel Inventory, the results of the study indicate a very high level of flood vulnerability. It was found that 58.4% of the total channel length did not meet the safety threshold criteria (freeboard < 30 cm) for the design flood discharge. The accumulation of surface runoff and domestic waste caused excess capacity of 41.6% at critical points, especially on Jalan Gajah Mada and Jalan S. Parman which flow into the Babura River. This decline in performance was significantly influenced by inadequate measurements.

Penerapan Algoritma Greedy pada Sistem Penjadwalan Cerdas Asisten Laboratorium Berbasis Kompetensi
type: item
description: Manual scheduling of laboratory assistants often leads to several issues, including schedule conflicts, uneven workload distribution, and mismatches between assistant competencies and practicum requirements. This study aims to develop a web-based laboratory assistant scheduling system by applying a Greedy algorithm that integrates multiple parameters, including competence, time preference, experience, and workload. The scheduling problem is formulated using an objective function and constraints to ensure a structured and reproducible solution. The Greedy algorithm is implemented using a hierarchical priority mechanism to select the best candidate at each assignment step. The evaluation was conducted using real-world data consisting of more than 200 practicum schedules and 30 laboratory assistants. The results show that the system successfully generates conflict-free schedules, with 66.7% of assignments meeting strict competency criteria and 80% matching assistants' primary time preferences. The workload distribution is also relatively balanced among assistants. In terms of efficiency, the system reduces scheduling time from 2–3 days to less than 10 second, achieving more than 99% improvement compared to manual methods. These findings indicate that the Greedy algorithm is effective in producing a fast, objective, and adaptive scheduling system.

Implementasi Cluster Proxmox dengan Fitur High Availability pada Laboratorium Sysadmin Universitas Amikom Yogyakarta
type: item
description: Ketersediaan tinggi pada infrastruktur virtualisasi kampus krusial untuk menjaga kesinambungan pembelajaran, namun pemilihan backend penyimpanan sering tidak berbasis bukti. Studi ini mengevaluasi ZFS lokal, NFS berbasis jaringan, dan Ceph terdistribusi pada Proxmox VE di dua skenario, kegagalan simpul komputasi dan kegagalan penyimpanan. Metrik layanan didefinisikan sebagai waktu failover sejak deteksi kegagalan hingga VM siap dan downtime yang teramati klien. Eksperimen dilakukan tiga ulangan per kondisi dengan jeda stabilisasi. Inferensi nonparametrik diterapkan, yaitu Kruskal Wallis dengan uji lanjut Dunn terkoreksi Holm, Mann Whitney U, Cliff’s delta, serta interval kepercayaan 95 persen berbasis bootstrap. Pada kegagalan simpul, ZFS paling cepat dengan failover 31±1 detik dan downtime 27±1 detik, melampaui NFS 45±2 detik dan 39±2 detik serta Ceph 60±2 detik dan 52±2 detik. Perbedaan global signifikan, H(2)=7,20 dan p=0,027, serta ZFS dibanding Ceph tetap signifikan, p=0,0219. Pada kegagalan penyimpanan, Ceph lebih cepat daripada NFS dengan failover 38±1 detik berbanding 47±2 detik dan downtime 33±1 detik berbanding 42±2 detik. Temuan menyarankan pemilihan backend selaras dengan risiko dominan, ZFS untuk kegagalan simpul dan Ceph untuk gangguan penyimpanan. Kebaruan terletak pada evaluasi lintas backend berbasis metrik layanan dengan analisis inferensial dan prosedur pengukuran yang replikatif.

Deteksi Sentimen Ujaran Kebencian dalam Tweet Media Sosial X dalam Konteks RKUHP Menggunakan Algoritma KNN
type: item
description: Penyebaran ujaran kebencian di platform media sosial, terutama dalam konteks undang-undang kontroversial seperti Rancangan Kitab Undang-Undang Hukum Pidana (RKUHP), menimbulkan tantangan kritis dalam menjaga diskursus publik yang konstruktif. Studi ini bertujuan untuk mengidentifikasi dan mengklasifikasikan sentimen dalam tweet yang berkaitan dengan RKUHP menggunakan algoritma K-Nearest Neighbor (KNN). Sebuah dataset berisi 703 tweet dikumpulkan melalui API X dengan kata kunci “RKUHP”, mencerminkan puncak percakapan online pada Juni 2023. Setelah disaring untuk konten Bahasa Indonesia, tweet diproses melalui pembersihan (penghapusan tanda baca, tag, URL), normalisasi, dan terjemahan ke dalam Bahasa Inggris. Penandaan sentimen dilakukan menggunakan TextBlob, dan kemudian diverifikasi oleh ahli linguistik untuk meningkatkan akurasi label. Term Frequency–Inverse Document Frequency (TF–IDF) diterapkan untuk ekstraksi fitur, dan cosine similarity digunakan sebagai metrik jarak. Beberapa nilai K (3, 5, 7, 9) diuji, dengan K = 3 menghasilkan akurasi tertinggi sebesar 56,74%. Evaluasi menunjukkan bahwa KNN dapat mendeteksi sentimen terkait ujaran kebencian dalam tweet Indonesia secara moderat, meskipun masih ada keterbatasan dalam menangani sarkasme, netralitas, dan ambiguitas terjemahan. Hasil ini mendukung upaya untuk meningkatkan deteksi ujaran kebencian otomatis dengan mengintegrasikan embeddings kontekstual, mengatasi ketidakseimbangan kelas, dan memanfaatkan pembelajaran ensembel.

Penggunaan Material Abu Batu dari Quary Batu Gong Sumbawa sebagai Subsitusi Pasir pada Campuran Beton
type: item
description: Pertumbuhan pembangunan infrastruktur di Indonesia yang menggunakan beton sebagai material utama menyebabkan peningkatan kebutuhan material penyusun beton, sementara ketersediaannya semakin terbatas. Kondisi ini mendorong perlunya inovasi teknik rekayasa beton yang ramah lingkungan namun tetap memperhatikan kekuatan dan kualitasnya. Di Kabupaten Sumbawa, ketersediaan pasir sebagai bahan agregat halus semakin berkurang, bahkan kualitasnya sering tidak memenuhi spesifikasi karena kadar lumpur melebihi 5% dan kadar organik mencapai 4–5%. Oleh karena itu, diperlukan material alternatif sebagai substitusi pasir, salah satunya abu batu yang memiliki butiran halus, seragam, dan bertekstur tajam sehingga berpotensi memperkuat ikatan dalam campuran beton. Penelitian ini bertujuan menganalisis pengaruh substitusi abu batu terhadap kuat tekan beton K- 250 dengan variasi komposisi 0%, 50%, dan 100% dari berat agregat halus. Metode yang digunakan adalah eksperimen laboratorium untuk mengetahui karakteristik material dan hasil uji kuat tekan. Hasil penelitian menunjukkan bahwa variasi 50% abu batu menghasilkan kuat tekan 240,48 kg/cm² (96,19% dari kuat tekan rencana) dan merupakan nilai terbaik, sedangkan variasi 100% abu batu menghasilkan kuat tekan terendah sebesar 206,42 kg/cm² (82,57% dari kuat tekan rencana).

Analisis RAB pada Proyek Revitalisasi Pagar Benteng Amsterdam dengan AHSP 2022 dan 2024
type: item
description: Benteng Amsterdam memerlukan revitalisasi berupa pemugaran pagar sepanjang 300 meter dengan tinggi 1,5 meter. Dalam proses pemugaran tersebut, penyusunan Rencana Anggaran Biaya (RAB) menjadi hal yang sangat penting. Untuk mengetahui besarnya anggaran biaya pembangunan pagar Benteng Amsterdam menggunakan metode Analisa Harga Satuan Pekerjaan (AHSP) tahun 2022 dan 2024, serta mengetahui selisih anggaran biaya antara kedua metode tersebut. Hasil penelitian menunjukkan bahwa terdapat perbedaan biaya antara AHSP 2022 dan AHSP 2024 pada masing-masing jenis pekerjaan. Pada pekerjaan persiapan, pondasi, plesteran, dan pengecatan, AHSP 2024 menghasilkan biaya yang lebih rendah dibandingkan AHSP 2022. Namun, pada pekerjaan pasangan dan beton, biaya menggunakan AHSP 2024 justru lebih tinggi. Perbedaan ini disebabkan oleh variasi nilai koefisien tenaga kerja, bahan, serta perubahan komponen material dalam masing-masing standar. Kesimpulan dari penelitian ini menunjukkan bahwa total anggaran menggunakan AHSP 2022 sebesar Rp 682.475.917,12, sedangkan dengan AHSP 2024 sebesar Rp 668.425.595,55. Terdapat selisih sebesar Rp 14.050.321,56 atau sekitar 0,021%, yang menunjukkan bahwa AHSP 2024 menghasilkan anggaran yang lebih rendah dan dinilai lebih efisien untuk proyek ini.

type: item
description: Infrastruktur jalan memegang peranan penting sebagai sarana penghubung antarwilayah yang mendukung kelancaran mobilitas masyarakat. Di Desa Oelnasi, Kecamatan Kupang Tengah, Kabupaten Kupang, Provinsi Nusa Tenggara Timur, jalan masuk di Jl. Bendungan telah mengalami kerusakan parah selama lebih dari satu dekade sehingga menjadi isu penting yang perlu mendapatkan perhatian. Masyarakat Desa Oelnasi sangat memerlukan akses jalan yang layak untuk aktivitas sehari-hari, terutama dengan pertumbuhan penduduk yang pesat dan posisinya sebagai jalur menuju wisata Bendungan Manikin. Beragam metode penentuan daya dukung tanah dapat menghasilkan nilai berbeda meskipun pada objek uji yang sama. Pengujian California Bearing Ratio (CBR) merupakan metode standar yang digunakan untuk mengevaluasi kapasitas dukung suatu tanah, di mana nilainya dapat ditentukan melalui investigasi laboratorium maupun lapangan. Riset ini disusun dengan tujuan menginvestigasi hubungan korelatif antara nilai CBR lapangan yang diperoleh dari uji Dynamic Cone Penetrometer (DCP) dan nilai CBR laboratorium. Data sekunder yang digunakan meliputi hasil pengujian DCP di enam lokasi berbeda, sementara data primer mencakup analisis karakteristik fisik tanah, pengujian Modified Proctor, dan pengujian CBR laboratorium terhadap enam contoh tanah. Analisis dilaksanakan dengan menerapkan formula matematis untuk merumuskan persamaan regresi dan korelasi. Temuan penelitian mengindikasikan persamaan CBR-DCP = 0,1272, yang secara konklusif menunjukkan tidak adanya pengaruh yang signifikan dengan nilai CBR serta nilai DCP.

Pengaruh Berbagai Jenis Hidrokoloid Terhadap Karakteristik Tekstur Lembaran Buah Ditinjau Secara Fisik dan Sensori
type: item
description: Fruit leather (lembaran buah) merupakan produk olahan buah yang dikeringkan dan dibentuk menjadi lembaran tipis yang mudah dibentuk. Penelitian mengenai pengolahan lembaran buah telah banyak dilakukan, mulai dari konsentrasi hingga jenis hidrokoloid yang digunakan. Dalam pembuatan fruit leather, hidrokoloid berperan sebagai bahan tambahan untuk meningkatkan mutu produk. Berbagai penelitian menunjukkan bahwa penambahan jenis hidrokoloid memberikan pengaruh bervariasi terhadap karakteristik fisik dan sensori lembaran buah, namun belum ada kajian pustaka yang secara khusus membahas pengaruhnya terhadap mutu. Kajian ini bertujuan mengetahui pengaruh jenis hidrokoloid terhadap karakteristik tekstur fruit leather secara fisik dan sensori menggunakan metode literature review dari artikel jurnal tahun 2020–2024. Urgensi kajian ini adalah mengidentifikasi kesenjangan penggunaan hidrokoloid terhadap mutu lembaran buah untuk pengembangan penelitian lanjutan. Beberapa hidrokoloid umum digunakan, antara lain karagenan, CMC, agar-agar, gum arab, gellan gum, guar gum, xanthan gum, pektin, dan dekstrin. Hasil kajian menunjukkan semakin tinggi konsentrasi hidrokoloid, nilai tekstur fisik seperti kuat tarik, hardness, springness, cohesiveness, dan gumminess meningkat, namun tingkat kesukaan panelis menurun. Setiap hidrokoloid memiliki konsentrasi optimum untuk menghasilkan fruit leather dengan karakteristik fisik dan organoleptik yang dapat diterima.
