Abstract

Liquid smoke is a natural pesticide that can be produced quickly and has a low production price. Making liquid smoke is a combustion process carried out with limited air and as little fire as possible, only embers. Then, the smoke from the combustion process with limited air is channeled into a pipe with a cooling system separate from the combustion chamber. This research used a passive cooling system, soaking the heat exchanger pipe with water. The temperature of the smoke produced is kept stable in the range of 80-90 degrees Celsius. The heat exchanger pipe in this research is designed to reduce the heat from the smoke produced by combustion without producing significant air resistance. The most essential requirement is that it can be made with available materials and has low manufacturing difficulty. In selecting a prototype, a heat exchanger system design was produced using a 1.5-inch diameter iron pipe, easily found on the market. The flow of smoke to be cooled through the heat exchanger pipe is from top to bottom, preventing the resulting liquid from being trapped in the curves of the pipe and making it easier for air and smoke that is still hot to remain at the top of the pipe naturally.

Abstract

Plastic waste is increasingly difficult to control, particularly plastic beverage bottles and food packaging. This undoubtedly necessitates prompt action to mitigate the detrimental effects of plastic on the environment. The objective of this activity is to enhance the skills and abilities of utilising plastic waste for games and learning, thereby reducing environmental pollution caused by plastic waste in the living environment. The implementation of this plastic STEAM PKM activity employs a training methodology for children to create manual props for games and learning using plastic waste. Children are encouraged to analyse their own needs by watching STEAM media creation reference videos (Analysis), design the tools they wish to create, including preparing the necessary plastic materials (Design), realise the Design (Development), utilise the tool (Implementation), and provide feedback on their own work and that of their peers (Evaluation). The outcomes of the activity included the enthusiasm and eagerness of the 23 elementary school children who participated in the training, as evidenced by their keenness to create and learn to utilise plastic waste

Abstract

Protecting the environment and ensuring its sustainability for future generations are sustainable development goals (SDGs). A preserved environment and ensuring sustainability for future generations is a sustainable development goal (SDGs). Every human activity produces waste that, if not appropriately managed, can bring problems in the future. Before starting a production process that utilizes natural resources, a complete understanding of the "green economy" is required.  This activity aims to provide socialization and counseling for partners in the assisted village empowerment program (GDP) about the "green economy" as the first step in building a pineapple center assisted village in Mendelem village, Belik District, Pemalang Regency. The method used is participatory action research. Five steps are taken to use the method: socialization, training, technology application, mentoring, and evaluation. The results were: an increase in partners' understanding of green economy reached 17%; partners' understanding of green economy practices reached 70.37%.  The practice of a green economy has a higher score than understanding. Partners feel helped by the direct practice of the green economy concept in the production process of processed pineapples.

Abstract

This study is an experimental study in the manufacture of composite materials with coconut fiber powder reinforcement from coconut waste and aluminum powder from industrial waste. From this study, the characteristics of composite materials will be obtained with variations in the composition of coconut fiber powder and aluminum powder as reinforcement with a polyester resin matrix. This study is considered necessary to find composite materials that are not only superior in mechanical properties, but also optimal and utilize waste materials in large quantities that require proper management so as not to cause problems. The manufacture of this composite material uses coconut fiber powder, aluminum powder and polyester resin with a volume ratio of 30% coconut fiber powder, 30% aluminum powder, 40% resin, 40% coconut fiber powder, 20% aluminum powder, 40% resin, 45% coconut fiber powder, 15% aluminum powder, 40% resin, 50% coconut fiber powder, 10% aluminum powder, 40% resin, 60% coconut fiber powder, 0% aluminum powder, 40% resin. The process of making this composite material uses a press method with a vertical force pressure of 2,500 kg with sintering at a temperature of 150oC for 30 minutes. The characterization carried out includes the hardness and wear of each material composition. The hardness value closest to the hardness value of the comparative brake pads is the KL45AL15 specimen with an average hardness value of 33.1 kg/mm² with a composition of 45% coconut fiber powder, 15% aluminum powder, and 40% resin. And in the results of the brake pad wear test, the wear value closest to the wear value of the comparative brake pads is the KL60AL0 specimen with a wear value of 0.00252. with a composition of 60% coconut fiber powder, 0% aluminum powder, and 40% resin.

Abstract

Kegiatan pengabdian ini bertujuan meningkatkan efisiensi pengolahan bawang merah di Kelompok Tani Blimbing Jaya, Desa Morobongo, Temanggung, yang selama ini terkendala metode pengirisan manual yang lambat (3-4 jam/50 kg) dan tidak seragam. Solusi yang ditawarkan adalah pelatihan penggunaan mesin pengiris bawang kapasitas 50 kg/jam melalui pendekatan partisipatif selama 2 hari, meliputi teori, praktik, dan pendampingan. Hasil evaluasi menunjukkan peningkatan signifikan pengetahuan peserta (nilai post-test 83,2 vs pre-test 58,4; p<0,05), dengan 88% peserta mampu mengoperasikan mesin mandiri. Produktivitas meningkat 66% dalam 5 bulan (dari 180 kg menjadi 300 kg/bulan) dengan efisiensi waktu 10 kali lipat. Kendala utama berupa keterbatasan jumlah mesin (2 unit) dan infrastruktur listrik diatasi melalui sistem peminjaman kelompok. Kegiatan ini membuktikan efektivitas teknologi tepat guna berbasis pelatihan praktis dalam meningkatkan daya saing usaha tani skala kecil.

Abstract

Technological advancements, including 3D printing, enable the creation of prototypes from digital designs using 3D printers. A popular method is Fused Deposition Modeling (FDM) with thermoplastic materials such as Acrylonitrile Butadiene Styrene (ABS), valued for its quality and affordability. In 3D printing, nozzle temperature and infill type influence the mechanical properties of printed objects. This study aims to determine the tensile strength of ABS with variations in nozzle temperature and infill type. Tensile test results show that a 230°C nozzle temperature produces higher yield strength for most infill types compared to 240°C. The 240°C setting tends to increase maximum tensile strength for grid and concentric infills, but not for gyroid and lines. The concentric infill type exhibited the highest elongation at both temperatures, indicating greater ductility compared to other infill types. These findings are expected to serve as a reference for optimizing printing parameters.
