Abstract

Refrigerant that is released into the environment will damage nature because of the chlorine. In addition, refrigerant is also a toxic substance and will damage the central nervous system and cause negative cardiovascular effects. To reduce the release of refrigerant into the environment, in this technical guidance, AC and refrigerator technicians were chosen as partners. AC and Refrigerator technicians are people who direct contact with the refrigerant. Offline Technical Guidance was carried out in the workplace by following strict health protocols during the covid 19 pandemic. For the provision of materials that do not use equipment, technicians were given via zoom meeting to reach all technicians at once. From the result of questionnaires , it was found that AC and refrigerator technicians have a good understanding of the effect of refrigerant on the environment, the effect on humans or the technicians themselves, the history of refrigerant, handling used refrigerant and safety and health at work.

Abstract

Abstrak - Usaha olahan yang menjadi khas Kediri adalah sambel kacang atau sering dikenal dengan sambel pecel yang mempunyai rasa gurih dan pedas. Mitra dari pengabdian masyarakat ini adalah usaha sambel kacang milik Ibu Erni yang didirikan tahun 1998. Proses pengolahannya adalah yang pertama menyangrai kacang sampai matang, kemudian mengiling bersama bumbu dan mengemasnya. Dalam proses penggilingan kacang diperlukan jarak yang lumayan jauh karena harus menggiling ke pasar. Dan di penggilingan juga beresiko untuk tercampur dengan sisa gilingan dari penggilingan yang sebelumhya, sehingga bisa mempengaruhi rasa dan kehigienisan sambel kacang tersebut. Asalah mitra adalah: 1. Aspek produksi (permasalahan menyangrai, penggilingan dan pengemasan); 2. Aspek pemasaran. (mendaftarkan PIRT, pendampingan pemasaran; pembuatan laporan keuangan secara sederhana dan pemasaran e-commers)

Abstract

Wood pellet is an alternative fuel made from wood waste, is one of the renewable fuels that is environmentally friendly, has a cylindrical shape and is hard, this is one of the energy conversions where the process of changing the energy form of wood waste which is randomly sized is converted into a cylindrical pellet form. This service is carried out to determine the impact of rising fuel prices on the pattern of fuel use in the tofu production process in Kab. Therefore, it is necessary to analyze the efficiency of the system analyzed, namely the efficiency of the combustion system in the production of tofu. What is known is the direct energy input in each soybean cooking process and the pattern of energy use in tofu production. From the analysis that has been done to get wood pellet fuel to get maximum results for soybean cooking in a burning time for 1 hour it takes 1/2 kg of wood pellets, if done one day by burning for 8 hours in the soybean porridge cooking process it takes 4 wood pellets kg.

Abstract

Sumbereja wetan village is located in ngunut district, tulungagung regency. The problem obtained is regarding the amount of shipping or distribution costs of production pos bags to UMKM. The method used in this problem is the Vogel 'Approximation Method (VAM) method, with the Quantitatif Management (QM) program. This method is used to manage distribution from sources that provide the same product, to several destinations that require optimal transportation. The results of this study showed that using the old method would cost more Rp. 46.330.000,-, whereas if you apply the transportation method using the VAM method/QM software, the cost is Rp. 39,220,000,-. So that the VAM method with QM software is more effective and can save shipping costs as much as 18%.
