Abstract

Penanganan limbah kelapa sawit terutama pelepah kelapa sawit menjadi perhatian khusus. Hal ini disebabkan karena minimnya optimalisasi limbah saat ini terutama pada Industri Kecil dan Menengah khususnya pada kelompok tani. Melimpahnya pelepah kelapa sawit yang berserakan di kebun diakibatkan belum diolahnya pelepah menjadi produk bernilai tinggi. Beberapa produk yang dapat dihasilkan dari limbah pelepah kelapa sawit adalah pupuk, pakan ternak, tali serat dan biopellet. Kendala yang dihadapi oleh mitra adalah tidak memiliki mesin pencacah pelepah kelapa sawit sebagai bahan baku pembuatan produk tersebut. Minimnya pengetahuan dalam merancang mesin pencacah pelepah kelapa sawit dan minimnya modal dalam pengadaan mesin tersebut menambah bagian permasalahan dari mitra usaha ini. Melalui Program Kemitraan Masyarakat ini tim menawarkan solusi untuk merancang dan menerapkan mesin pencacah pelepah kelapa sawit sebagai upaya pemecahan masalah tersebut. Tahapan pelaksanaan kegiatan yang direncanakan seperti: Analisis Situasi pada Unit Usaha, Merancang dan membuat mesin pencacah pelepah kelapa sawit, Melakukan pelatihan pengoperasian dan maintenance mesin sekaligus penyerahan mesin kepada Unit Usaha, Evaluasi Program Kegiatan. Diharapkan dengan Program Kemitraan Masyarakat ini dapat mereduksi limbah pelepah kelapa sawit, diversifikasi atau variansi produk dan meningkatkan pendapatan pelaku usaha dari unit Industri Kecil dan Menengah dalam hal ini kelompok tani.

Abstract

The industrial sector is the backbone of the country in building the defense sector and economic stability that needs to maintain productivity and be competitive. One of the companies that manufacture automotive components, Mitsubishi, manufactures automotive components and must have zero defect requirements. However, in practice, it was found that 1 (one) unit of CJM had a brake caliper malfunction in the condition that the unit was ready to be sent to the carpool consumer of a company that produces automotive components. The damage is a discrepancy in the diameter of the piston seal, which closes the gap between the piston and the piston housing, allowing for brake fluid leakage, which affects the "zero defect" commitment. Through the application of the Root Cause Corrective Action (RCCA) method with the formation of a Root Cause Investigation (RCI) team, an investigation was carried out to find the root cause of the failure. However, the data processing results of the diameter of the seal thickness obtained have a Cp value of 0.98 and a Cpk of 0.81, which means the process has not been able to work optimally. Therefore, we decided to make some improvements, adding Standard Operating Procedures (SOP), Work Instructions (WI), and making Poka-Yokes as corrective actions in dealing with this problem. After almost 3 months since the investigation began, the data processing results on the piston seal were Cp = 1.86 and Cpk = 1.80.

Abstract

Every workplace has a risk of occupational accidents. A work accident is an unplanned and uncontrollable event caused by human factors, the Environment, machines or a combination of the three occurring during the work process that is likely to cause injury, property damage and death or other undesirable events. Work accidents that occur always bring losses such as a decrease in the company's productivity because employees cannot work optimally, loss of manpower and of course reduce the company's profits. This research aims to analyze the order of priority for handling potential hazardous hazards that result in work accidents, analyze high-risk processes/activities that result in work accidents, and analyze control recommendations for potential hazards that have the risk of resulting in work accidents. The analysis method that will be used is the failure mode effect analysis (FMEA) method. The results of the study show that the potential danger of exposure to hot temperatures (melting process) has an RPN value of 297.7 so that the most risky production process is the process of forming or molding raw materials. The priority order of handling potential hazards from the glass bottle production process is exposure to hot temperatures, noise, exposure to glass bottle fragments, suffocation and being pinched by machines/conveyors. The controls that must be carried out are providing fans, providing insulation and shields, and providing drinking water so that the operator does not suffer from dehydration.

Abstract

SMA Yadika 5 has one of the goals, namely "Providing knowledge and skills in the field of entrepreneurship and plant cultivation that are beneficial for students and the surrounding environment". In cultivating plants, supporting materials such as organic fertilizer are needed. Coconut juice is often used as a cooking ingredient in household activities, where the pulp from coconut juice that is no longer used can generally be reprocessed into organic fertilizer. Organic fertilizer can improve the chemical, physical and biological fertility of the soil, in addition to being a source of nutrients for plants. Organic fertilizer made from coconut pulp waste for plants can be one way to carry out the goals of SMA Yadika 5. In addition, it can be a solution for agriculture or plantations for housewives or family members of SMA Yadika 5 students in urban areas. Based on the analysis of the situation around us, it turns out that teenagers are interested in learning this knowledge but have not had the opportunity because there has been no training and counseling in managing waste. The target of this training in managing household organic waste from coconut pulp is male and female teenagers at SMA Yadika 5, Kembangan District, West Jakarta.
