Abstract

Drought severely impacts livestock activities as it becomes increasingly difficult to find green feed for cattle. The hot weather causes the food stock to dry and makes it impossible for cattle to eat. The damage to the cattle food supplies exacerbates this because of termites, especially dry straw. This condition makes the Sedyo Mulyo farmer group worried about the sustainability of cattle food stock. They usually easily get the food stock only from their neighborhood, but because of extreme weather, they have to look for it in areas far from home. Sometimes they also have to buy it if the stock is empty. In response to this problem, it is necessary to preserve cattle food stock when conditions are abundant and use it during the dry season. Cattle food stock preservation is one way to support the conservation of food stock programs. Many methods can be used to preserve cattle food stock today, and the silage method is one of the best of it. Silage is a feed preservation technique with a fermentation process. The purpose of silage is to maintain and reduce the loss of nutrients for future use. This community service program will provide knowledge and training in making this method for cattle food conservation. It is carried out by sharing knowledge sessions and practicing to make silage from greenery and rice straw. The results showed that the Sedyo Mulyo group members had a high understanding of preparing and making silage independently.

Abstract

Alat pelindung diri (APD) adalah seperangkat alat yang digunakan untuk melindungi diri dari bahaya kecelakan kerja. Safety shoes adalah salah satu contoh APD yang digunakan sebagai pelindung kaki dari benda jatuh. Toe cap adalah struktur utama safety shoes yang berperan dalam menahan impak dari benda jatuh tersebut. Saat ini material pembuat toe cap masih di dominasi oleh material metal. Secara umum penggunaan material metal didasarkan pada kekuatan yang tinggi. Namun metal memiliki kelemahan jika dibanding dengan material polimer dan komposit, yaitu   memiliki massa yang tinggi, oleh karena itu terdapat perasaan kurang nyaman saat dipakai. Jika dipakai secara terus menerus pada jangka yang Panjang dapat berdampak kurang baik bagi kesehatan kaki. Selain itu, resiko jatuh saat menggunakan safety shoes semakin meningkat saat melakukan aktifitas gerak melintasi banda. Ini dikarenakan terjadinya perubahan pusat masa, sehingga akan mengganggu keseimbangan. Salah satu solusi dari masalah tersebut adalah menemukan material pembuat toe cap dari bahan yang ringan namun kuat menahan beban impak. Pada penelitian ini dilakukan uji kharakteristik Impak dan Bending pada tiga variasi jenis komposit. Variasi serat karbon/akrilik (CA), variasi serat kaca/akrilik (GA) dan variasi Serat karbon/serat kaca/akrilik (CGA). Hasil uji bending menyebutkan jenis variasi CGA unggul jauh dari dua variasi lainnya. Sedangkan pada uji impak, jenis variasi yang unggul adalah CA.

Abstract

Karangharjo Village, Kragan Subdistrict, Rembang Regency, is a coastal village where the majority of the population works as traditional fishermen using boats <5 GT. Fish catch productivity is greatly influenced by the seasons, especially during the west wind period when catches drop dramatically to <10 kg/day. The low level of education, with 48.22% of the population only completing primary school, further limits skills and income levels. This situation leads to poverty and livelihood uncertainty. The objective of this community service programme is to develop alternative livelihoods through welding training using Shield Metal Arc Welding (SMAW) techniques as a strategy for diversifying fishermen's livelihoods. The implementation methods include planning, theoretical training, basic welding practice, application of workplace safety standards, and evaluation of participants' skills. The results of the programme show an increase in welding knowledge and skills among the 20 trainees, with some of them having the potential to develop their own welding businesses. This programme contributes to the achievement of the Sustainable Development Goals (SDGs), particularly Goal 8 (Decent Work and Economic Growth) and Goal 17 (Partnerships for the Goals), and supports the strengthening of the local economy through the empowerment of fishermen.
