Abstract

Abstract— The harvesting of palm oil in Indonesia, is still done manually. This research analyzed the movement of the palm oil loading process manually, which risks of Musculoskeletal Disorders (MSDs) to workers. The methods used in this study include observation, interviews, the Nordic Body Map (NBM) Questionnaire, the Natural Range of Motion (ROM), and biomechanical load calculations. NBM is used to identify complaints of the worker’s body parts. The ROM method is used to analyze the risk of body movements when carrying out palm oil loading activities, and the calculation of biomechanical loads is to determine the burden on the worker's body parts. The results showed that there are three parts of the body involved in the process of loading palm oil so that workers often complain of pain, namely the shoulders, neck, and back. The biomechanical load that occurs on the back of the worker is 4866.36 N. This value exceeds the safety limit recommended by the National Institute of Occupational Safety and Health (NIOSH) which is as high as 3400 N. Analysis using ROM found that the existing loading process of oil palm causes shoulders, neck, and back to form angles of 120°, 31° and 12°, respectively. This angle is in the danger zone based on ROM. Improvements are made by changing the work posture in the loading process of oil palm and giving changes to the body angle to 90° on the shoulder, 14° on the neck, and 2° on the back, which are already in the safe zone. The biomechanical load on the back after the improvement also decreased to 3287.38 N

Abstract

Abstract Riau is one of the areas with the largest oil palm plantation area in Indonesia. In general, oil palm has three types of waste, including: solid waste, liquid waste, and gas waste. Solid waste consists of empty bunches, midribs, stems and mesocarp fibers. The frond waste is generated when trimming the midrib at the time of harvesting oil palm fruit bunches. The oil palm midrib consists of rachis (leaves), pinnacs (leaves), and spines (sticks). The number of leaflets on one midrib ranges from 250-400 leaflets located on the left and right of the midrib. Each leaflet consists of a stick and two leaves. The process of separating sticks is still done manually, so it takes a long time to separate them. So in this study, we designed a palm stick machine using CAD. Designing with CAD provides many advantages including making it easier for designers to design, reducing time, and reducing costs during design. There are three design pictures of palm oil stick waste processing machines. Based on economic calculations, tools and materials needed and processing time, design drawing C is the choice. Next, build a waste treatment machine with reference to the selected design Keywords: stick waste, CAD, Palm Oil

Abstract

UD. SJ is one of the SMEs in Pelalawan with the main product in the form of furniture. Problems that are often faced by UD. SJ is the distribution and distribution of costs for product sales that are not optimal, lack of calculations, lack of recording and bookkeeping, thus making UD. SJ sometimes takes a loss. So the formulation in this study is how to optimize the distribution costs of UD products. SJ, the distribution process is influenced by the distance traveled, the cost of the trip, and the number of vehicles and drivers. The purpose of the study was to determine the optimal cost comparison of product distribution in UD. SJ. The method used is the stepping stone transport method). The results showed that the calculation of the distribution costs of furniture products from UD. The optimal SJ using the stepping stone method manually is Rp. 31,233,751.
