Abstract

Telapak tangan minyak adalah salah satu perkebunan yang memiliki peran penting bagi sub sektor perkebunan. Produktivitas tandan buah kelapa sawit meningkat dengan cepat dan mencapai maksimum pada usia 8-12 tahun, kemudian menurun secara bertahap hingga usia 25 tahun. Kelas kesesuaian tanah dapat mempengaruhi produktivitas kelapa sawit. Penelitian yang dilakukan di Divisi II Kebun Matapao Pt. Socfindo. Ini dilakukan pada Mei 2021 hingga Juli 2021. Penelitian menggunakan analisis deskriptif, menggunakan produktivitas data kelapa sawit di Divisi II Kebun Matapao. Hasilnya menunjukkan bahwa jumlah rata -rata tandan per pohon pada tahun 2011 hingga 2013 meningkat 1,49% dari potensi, berat rata -rata tandan menurun 5,82% dari potensial, dan produktivitas rata -rata tikat buah kelapa sawit menurun 15,10% dari potensi. Kesenjangan produktivitas kelapa sawit di Divisi II Kebun Matapao Pt. Socfindo dipengaruhi oleh faktor iklim, usia faktor tanaman dan jumlah pohon per hektar.

Abstract

Seblak is a food that has seen an increase in demand in recent years, and is a promising culinary business that can be run with a small capital. UD. XYZ is a seblak business that started selling seblak in early 2022 in West Aceh and wants to maximize the profits from its seblak sales. One method that can do this is Linear Programming, which can determine decision-making that can group limited materials or resources to achieve an optimal or best solution. From UD. XYZ's weekly sales data, it can be transformed into a mathematical model that helps to find the maximum function of the profit from seblak sales. The linear programming calculation process in this study uses the Lingo 18.0 software to solve linear programming problems, which will be continued with the linear graph visualization of the objective function with the MATLAB software. The results of the study show that the maximum profit that will be obtained by UD. XYZ in one week is Rp. 420,000/week, this profit is already categorized as net profit that can be used for the development of UD. XYZ's seblak business. Of the three variables X1 (seblak noodles and crackers), X2 (seblak eggs), and X3 (seblak chicken/feet), variables X1 and X2 have the potential to increase maximum profit if increased. In this study, the objective point is also on the point axis (X1=0, X2=0, and X3 = 175).

Abstract

Vertical Clarifier Tank (VCT) has a very crucial role to separate oil, water and sludge by gravity, where oil with a smaller specific gravity of 0.8 grams / cm3 will be in the uppermost layer, while water whose specific gravity is 1 gram / cm3 will be in the middle layer, and sludge with a density of 1.3 grams / cm3 from the Vertical Clarifier Tank (VCT). The experimental design of this study was to determine the appropriate depth of the inlet pipe to obtain low levels of impurities during oil extraction. The results of the study obtained from variations in the depth of 25 cm, 40 cm, 55 cm, and 70 cm inlet pipes used as the inflow of crude oil from Crude Palm Oil with variations in sedimentation time of 100 minutes, 120 minutes, 140 minutes, 160 minutes, 180 minutes, and 200 minutes, obtained the least level of impurities in the Inlet Pipe which has a length of 55 cm with a variable sedimentation time of 200 minutes.

Abstract

PT. Aceh Lampulo Jaya Bahari is a nautical product manufacturer based in the Lampulo fishing port, Banda Aceh, Indonesia. Productivity is a comparison of input and output that indicates how effectively resources are managed and exploited to obtain the best results. High production means there is less likelihood of delays. PT. Aceh Lampulo Jaya Bahari's productivity achievement indicator values fluctuate annually, with some years seeing low or high production.  The purpose of this study is to identify productivity-influencing elements, as well as to estimate the level of labor productivity, production amount, total productivity, and the difference in production amount when processing tuna cubes at PT. Aceh Lampulo Jaya Bahari. This study examines monthly production data from 2023 to determine worker productivity and output. The method is to measure partial and total productivity and then launch monthly productivity changes. The study's findings demonstrate that labor productivity and tuna cube output are higher than number one, indicating productive performance. PT. Aceh Lampulo Jaya Bahari met its production objective of 350 kg per month, with an average total labour productivity of 2.6%. This study advises that firms maintain production consistency and form a network of collaborating partners to ensure raw material availability.

Abstract

This study optimizes resource allocation in Islamic banking using Design of Experiments (DOE) and Orthogonal Arrays (OA) to minimize simulation scenarios while ensuring statistical validity. Focusing on a West Aceh-based bank (4 tellers, 2 CS agents, 5 ATMs), the research addresses operational inefficiencies prolonged queues, resource misalignment conflicting with Sharia principles of efficiency (israf avoidance) and equity, exacerbated by seasonal demand fluctuations. A Full Factorial Design initially generated 40 scenarios (200 iterations), imposing high computational burdens. OA techniques reduced scenarios to 9 (77.5% fewer iterations, 45 total), maintaining a 95% confidence level (z-score=1.96) and 1-minute margin of error. Utility differences between methods were marginal (CS:1.3%, Teller:1.5%, ATM:2.3%) and statistically insignificant, confirming OA’s reliability. Critical interactions (e.g., CS=1 paired with all Teller levels) and balanced configurations (Teller=3 + ATM=3 “sweet spot”) were identified, despite minor imbalances (e.g., ATM=4 tested once). The approach advocates data-driven policies deploying ATMs during CS shortages and optimizing human-technology ratios aligning with Sharia ethics by reducing waste and enhancing equity. With 77.5% computational savings, this methodology offers scalable solutions for Islamic finance and dynamic sectors, bridging statistical rigor with ethical governance in resource optimization.

Abstract

CV Nadha Furniture is a business entity operating in the furniture sector which produces various types of processed wooden goods that have sales value such as doors, frames and windows. The aim of this research is to identify potential hazards at each step of the work and carry out risk assessments, prevention and control of potential hazards found in the production process. The method used in this research is Hazard Identification and Risk Assessment & Risk Control (HIRARC). Based on the results of identifying potential hazards at CV Nadha Furniture, it has 5 potential hazards in the high category and 4 potential hazards in the medium category in the production process, including the raw material selection station has 1 potential hazard in the high category, the raw material cutting station has 2 potential hazard categories. high and 1 potential hazard in the medium category, the pattern forming station has 2 potential hazards in the high category and 1 potential hazard in the medium category, and the vinyl installation station and final checking and packaging stations have 2 potential hazards in the medium category. To minimize the level of risk from potential dangers, risk control is carried out which can be done by using gloves, safety helmets, masks and safety shoes as well as providing job training and conducting safety talks before carrying out work..
