Abstract

Local farmers in Sungai Awan Kanan Village are one of the supporting sources of food for consumers around Ketapang Regency, West Kalimantan. With traditional skills they are able to produce agricultural products that can compete with modern agriculture. They always produce fresh vegetables every day for family and community needs. Behind it all, there are several weaknesses that they currently feel, including; cheap prices at the collector level (prices become a game for certain parties), fresh vegetables cannot last long due to limited supporting facilities. Meanwhile, on the other hand, there are opportunities that actually open the chain of their problems, such as; the emergence of supermarkets and modern markets that require supplies. The aim of implementing this community service is to encourage the strength of local communities in developing agricultural products, especially vegetables, through packaging methods. The community is facilitated by providing modern packaging for the agricultural products they get. With this community service program in the form of training regarding the development of agricultural products through packaging, it is hoped that it can increase public knowledge about how to increase income through packaging methods applied to agricultural products. After the training, almost all training participants realized that the packaging methods applied to agricultural products could have a good effect on the sales of their agricultural products.

Abstract

An attempt has been made to extend the service life of mahogany wood (Swietenia mahogany) by preserving it. The purpose of this study was to determine the mechanical properties of mahogany wood after cold soaking with preservatives of cocoa pods extract (Theobroma cacao). This research uses an experimental method of cold soaking which is carried out in the Material Testing Laboratory of the Mechanical Engineering Department of Padang State Polytechnic. The preservation process used cacao pod extract preservative solution at concentrations of 0%, 3%, 6%, 9%, 12%, and 15%. The observed responses were the preservative retention values and mechanical properties (compressive strength parallel to the fiber direction, flexural strength, and surface hardness) of the wood. The preservation method applied was cold soaking for 120 hours. The increase in retention value was directly proportional to the increased concentration of extract added. The improved properties of wood (compressive strength in the grain direction and flexural strength) also increased with increasing extract concentration. The results obtained showed that the highest value was obtained at a 15% concentration of the added extract with a retention of 7.6078 kg/cm2, a compressive strength parallel to the fiber of 227.92 kg/m2, and a flexural strength of 387.82 kg/m2. This data shows that cocoa pods extract has the potential to be used as an environmentally friendly wood preservative.

Abstract

Excavators are heavy equipment commonly used in projects such as bridge construction and land clearing. In the hydraulic system of an excavator, there are components such as the main pump, regulator pump, control valve, and pilot valve, which function to supply power that will then be converted to actuator components such as the swing motor, track link, boom, arm, and bucket. Improper maintenance scheduling can lead to unpredictable time and cost losses.In conducting this research, the author used several methods to obtain the necessary data, including surveys, interviews, and discussions with mechanics.The type of maintenance carried out at BAPPEDA of the Ketapang Regency Research and Development Agency Regency is Breakdown Maintenance. Maintenance planning is always prepared at the beginning of the year and then documented at the end of the year. Preventive maintenance is only conducted to assess the condition of components and to prepare for necessary repairs. Repairs are carried out based on the planned maintenance schedule as well as unexpected damage that occurs in the field. With proper maintenance scheduling, it is expected to have a positive impact on the service life of several components in the excavator's hydraulic system.

Abstract

Study the effect of cooling media variations on the hardness value of AISI 1020 gear sprocket alloys and tin with heat treatment. This research is to find out the combination of AISI 1020 gear sprocket with tin, with a heat treatment process carried out with temperatures reaching 700ºC and held for 15 minutes, with air conditioning media, SAE 40 oil and water, and carried out heat treatment with hardness testing on each material with differences in the cooling media using the Rockwell method. From the results of the test, different cooling media, different cooling rates are obtained and produce different hardness changes. In testing the data obtained in accordance with the results of heat treatment which is continued by cooling the air gives the lowest hardness value (51.2 HR), while cooling with oil and water is higher, respectively 54 HR and 58.4 HR.

Abstract

ST37 equivalent steel is widely used in engineering applications due to its high ductility; however, its relatively low hardness limits its performance in wear-related components. This study investigates the effect of annealing temperature variations and different oil quenching media on the hardness of ST37 equivalent steel. Specimens were annealed at 750°C, 850°C, and 950°C with a holding time of 10 minutes, followed by quenching in three types of oil: SAE 15W-40 mineral oil, SAE 10W-40 semi-synthetic oil, and SAE 10W-40 fully synthetic oil. Hardness measurements were conducted using the Rockwell B scale (HRB) at five different points on each specimen. The results indicate a consistent increase in hardness with increasing annealing temperature for all quenching media. The highest hardness value, 43.4 HRB, was obtained at 950°C using fully synthetic oil, representing an improvement of approximately 4.58% compared to the untreated material. Among the tested media, fully synthetic oil exhibited the most effective cooling performance. These findings demonstrate that both annealing temperature and oil type significantly influence the hardness characteristics of ST37 equivalent steel.
