Abstract

Muara Kambang is a coastal area where the Kambang river begins. The abrasion that occurred in this place caused blockage of the shoreline and eroded the river mouth. One alternative solution to abrasion at the river mouth is to build a jetty. Damage to the beach structure (jetty) was caused by the arrival of large enough sea waves, so that the coastal structure could not withstand these waves. The purpose of this study was to determine the stability of the jetty from natural stone or tetrapod to waves. Wind data is used to determine the analysis of significant wave height, then the theoretical distribution of Normal, Gumbel, and Person III can be determined. Furthermore, the calculation of the significant wave period, the calculation of the depth of the building foot, up to the calculation of the safety factor against rolling and shear. From the calculation results, the following results are obtained: Natural stone: carrying capacity (Qult): 360,540 kg/m3, soil pressure (Qall): 120,180 kg/m2, allowable load: 1,203,607,7 kg, control of rolling (FR) 1.84 ≥ 1.5, control against shear (FS): 1.634 ≥ 1.5, and control against collapse 1.203,602.7 ≥ 107,280,6852. Tetrapod: carrying capacity (Qult): 407,340kg/m3, ground pressure (Qall): 135,780 kg/m2, allowable load: 1,536,350,7 kg, control over rolling (FR) 3,2 ≥ 1,5, control against shear (FS): 3.8 ≥ 1.5, and control against collapse 1,536,350.7 ≥ 437,380,324.

Abstract

Laterite nickel furnace slag is a by-product of the smelting process that still has the potential for further utilization; therefore, a comminution process is required to improve the efficiency of subsequent processing stages. This study aims to analyze the particle size distribution characteristics, determine the specific energy requirement, and calculate the Rittinger coefficient in the comminution process of laterite nickel furnace slag using a jaw crusher at PT Vale Indonesia Tbk. The research method involved crushing furnace slag using a jaw crusher with an operating power of 2.24 kW for 14.88 seconds, followed by particle size distribution analysis through sieve analysis based on the ISO 3310-1 standard. The equivalent diameter parameter was used to represent the feed size due to the irregular lump-shaped form of the material. The results showed that the equivalent diameter of the furnace slag feed was 53,435.77 μm (53.4 mm), while the characteristic product size (P80) was determined to be 1,580.09 μm (1.58 mm). The particle size distribution resulting from the comminution process exhibited a positively skewed pattern with a peak concentration at a particle size of 356 μm (70 mesh) and a frequency value of 0.58, indicating the dominance of particles within the intermediate size range (212–850 μm). The specific energy calculation showed an energy requirement of 38.74 kWh/ton to reduce the material size from feed to product. Based on the Rittinger’s law approach, the Rittinger coefficient was calculated to be 63,082.04656, representing the energy requirement characteristics associated with the formation of new surface area during the size reduction process. The findings of this study can serve as a basis for energy requirement estimation and comminution equipment specification planning for laterite nickel furnace slag processing on an industrial scale.

Abstract

Blast hole drilling is a critical stage influencing blasting success and the achievement of production targets in andesite mining operations at CV. Mitra Persada Batu Buil, West Kalimantan. The company set a production target of 60,000 m³/year, yet actual production reached only 53,000 m³/year. This study aims to analyze the productivity of the Furukawa CRD PCR 200 drilling rig, identify the factors influencing it, and evaluate production target achievement. The methodology employed included field surveys and quantitative analysis of data regarding cycle times, drilling speeds, work efficiency, and equipment availability. Research results indicate an actual drilling productivity of 29.41 m³/hour, compared to a recommended productivity of 46.35 m³/hour. Factors influencing drilling operations include an actual work efficiency of 58.97% (318.47 minutes), which could be improved to 71.85% (388 minutes) by reducing operational delays. Actual drilling output was 8–9 holes/day against a recommendation of 10 holes/day, with a drilling speed of 0.16 m/minute and a volume yield of 5 m³/meter. Metrics for Mechanical Availability (91.03%), Physical Availability (91.95%), Use of Availability (79.15%), and Effective Utilization (73.43%) indicate good equipment performance. Improving work efficiency and managing operational delays have the potential to support the achievement of the company's production targets.

Abstract

This study aims to evaluate the adsorption efficiency of Fe, Mn, and Pb metals in peat water using activated natural zeolite as an adsorbent and to assess the performance of the ICP-OES instrument. Peat water samples were collected from Banjar Regency with characteristics of pH 5.13, Fe concentration 3.141 mg/L, Mn 0.164 mg/L, and Pb 0.080 mg/L. The adsorption process was carried out in a batch system with variations in adsorbent mass (0.3–1.5 g per 100 mL) and contact time (15–60 minutes). Zeolite was activated using 1 N HCl and heated at 300°C. Metal concentration analysis was performed using ICP-OES. The results showed that the optimum condition was achieved at 1.5 g adsorbent mass (Fe at 45 minutes; Mn at 60 minutes), with the highest removal efficiency of 92.68% for Mn and 71.86% for Fe. The adsorption isotherm model for Mn followed the Freundlich model (R² = 0.9324), while Fe approached the Langmuir model with some anomalies. The ICP-OES instrument demonstrated excellent linearity with R² values close to 1.0000. This study proves that activated natural zeolite is effective in reducing heavy metal concentrations in peat water, particularly Mn and Fe.

Abstract

Kemacetan lalu lintas di persimpangan sering dipicu oleh pengaturan durasi lampu lalu lintas yang statis. Penelitian ini bertujuan mengembangkan sistem prediksi durasi lampu hijau adaptif berbasis algoritma YOLOv11n menggunakan dataset CCTV lalu lintas lingkup Jawa Barat sebanyak 868 citra dengan 9.166 objek kendaraan. Dataset diproses melalui rekayasa spasial serta augmentasi sebelum dilatih dalam empat skenario hyperparameter. Hasil eksperimen menunjukkan bahwa Skenario D dengan resolusi spasial 800x800 piksel dan 120 epoch menghasilkan performa paling superior. Model ini mencapai nilai mean Average Precision (mAP@0.5) sebesar 0,942, tingkat precision 0,890, recall 0,892, serta kecepatan inferensi responsif sebesar 8,1 ms per frame. Ketika diintegrasikan ke dalam sistem simulasi real-time, model terpilih terbukti sangat adaptif dalam mengoptimalkan durasi lampu hijau berdasarkan volume aktual kendaraan di persimpangan. Implementasi sistem ini mampu memberikan efisiensi pengurangan waktu hijau hingga 54,0% pada kondisi lalu lintas renggang dan mempertahankan stabilitas efisiensi sebesar 15,6% saat kondisi padat. Dengan demikian, sistem ini efektif mereduksi akumulasi waktu tunggu kendaraan yang tidak produktif dan berpotensi meminimalkan kemacetan persimpangan secara signifikan.

Abstract

Kegiatan belajar mengajar di SMA Islam Cikuya Bungbulang dihadapkan pada kendala keterbatasan infrastruktur fisik, yakni hanya memiliki 6 ruang kelas untuk menampung 162 siswa. Keterbatasan ini menyebabkan proses pembelajaran konvensional menjadi kurang efisien karena tidak adanya fleksibilitas pergantian ruang kelas. Oleh karena itu, penelitian ini bertujuan untuk mengimplementasikan sistem e-learning berbasis web sebagai wadah digital yang memungkinkan proses pembelajaran dilakukan secara asynchronous (tidak terikat waktu dan ruang) guna mengatasi kendala tersebut. Pengembangan sistem ini menggunakan metode Software Development Life Cycle (SDLC) Model Fountain yang memungkinkan pengerjaan setiap tahapan secara fleksibel dan tumpang tindih. Tahapan tersebut meliputi analisis, spesifikasi kebutuhan, perancangan (menggunakan pemodelan UML), implementasi (menggunakan framework PHP Laravel dan database MySQL), pengujian, penerapan (deployment), operasi, hingga pemeliharaan dan evolusi. Fitur utama yang dikembangkan mencakup manajemen pengguna, distribusi materi ajar, pengumpulan penugasan berbasis file, serta evaluasi kuis pilihan ganda otomatis. Hasil pengujian menggunakan metode Blackbox Testing menunjukkan bahwa seluruh spesifikasi fungsionalitas menu dan fitur utama sistem telah berjalan dengan baik dan sesuai dengan hasil yang diharapkan. Sistem ini juga telah berhasil beroperasi secara sinkron dan stabil di lingkungan server hosting. Dengan demikian, sistem e-learning ini terbukti mampu menjadi solusi yang efektif untuk memfasilitasi proses pembelajaran jarak jauh bagi guru dan siswa di SMA Islam Cikuya Bungbulang.

Abstract

Pengelolaan absensi guru secara manual di SD IT Nurul Iman Semarang rentan terhadap kecurangan, ketidakakuratan data, serta membutuhkan waktu yang tidak efisien dalam proses rekapitulasi kehadiran. Berdasarkan observasi awal, proses absensi konvensional menggunakan buku daftar hadir membutuhkan waktu rata-rata 5-10 menit per sesi, belum termasuk waktu rekapitulasi harian yang dikerjakan secara manual oleh staf tata usaha. Penelitian ini merancang dan membangun sistem absensi guru berbasis pengenalan wajah (face recognition) yang diimplementasikan sebagai aplikasi web pada SD IT Nurul Iman. Sistem dikembangkan menggunakan PHP dan MySQL sebagai backend, serta memanfaatkan library face-api.js dengan model TinyFaceDetector untuk proses deteksi dan ekstraksi fitur wajah secara real-time langsung di sisi browser (client-side). Verifikasi identitas dilakukan menggunakan metode Euclidean Distance dengan nilai threshold 0,38. Sistem menerapkan prinsip one face one person dengan mode verifikasi 1:1. Pengujian Black Box Testing terhadap 25 skenario menunjukkan hasil 100% berhasil. Pengujian akurasi face recognition menghasilkan True Acceptance Rate (TAR) sebesar 94,4% dan False Acceptance Rate (FAR) sebesar 1,6%, dengan rata-rata waktu respons verifikasi 1,8 detik.
