Abstract

Waste glass and piston can be used as alternative material to non-asbestos motorcycle brake pads based on their properties. Waste glass used as a reinforce, the piston used as a filler, and phenolic resin used as a binder. Those materials were mechanically transformed into powder with 60,100, and 60 mesh respectively. The glass, piston, and phenolic resins powder were varied into five different compositions which are A (10% glass, 50% piston, 40% phenolic resin), B (20% glass, 40% piston, 40% phenolic resin), C (30% glass, 30% piston, 40% phenolic resin), D (40% glass, 20% piston, 40% phenolic resin), E (50% glass, 10% piston, 40% phenolic resin). The powder was mixed at 45 rpm for 30 minutes, then 166 Bar initial pressure was applied in single action for 2 minutes, next it was pressed at 196 Bar in single action hot compacting at 150° for 5 minutes holding time. The green bodies were sintered at 150°C for 4 hours, finally those samples were evaluated by hardness test and wear test. The results show, the composition A has the closest hardness and wear value to commercial products, 40.549 HVN and 8.826x10-12 m3/m accordingly.Keywords: Brake Pads, Waste Glass, Waste Piston

Kegiatan yang dilakukan adalah pelatihan pengolahan kunyit menjadi serbuk kunyit asam instan dengan memanfaatkan teknologi Solar dehydrator. Metode pengabdian menggunakan pendekatan partisipatif terdiri dari pengamatan, pelatihan, dan evaluasi. Kuisioner diberikan kepada 27 responden, termasuk guru, dan orang tua siswa. Pretest dilakukan sebelum pelaksanaan pelatihan, dan dilanjutkan dengan post-test setelah para responden menerima pelatihan dan mencoba sendiri serbuk kunyit asam instan. Hasil evaluasi berdasarkan jawaban responden atas kuesioner yang diberikan menunjukkan peningkatan pengetahuan terkait kunyit asam sebanyak 81%, pengalaman mencoba sebanyak 37%, ketertarikan pembuatan sebanyak 17%, kepercayadirian untuk mengolah sebanyak 14% serta peningkatan pengetahuan sebanyak 11%. Hasil ini menunjukan bahwa pelatihan ini memberikan dampak positif bagi PAUD Nurul Huda

Abstract

Health is a fundamental aspect in supporting productivity, especially for teachers, who are educators of the nation's future generations. In environments prone to disease and unhealthy lifestyles, maintaining a strong immune system becomes a crucial priority. One natural and affordable way to enhance immunity is by consuming herbal drinks made from honey and medicinal plants. The objective of this community service activity was to conduct a workshop for PC Pemudi Persis Tarogong Kaler titled "Honey with All Its Nutritional and Vitamin Benefits Contains Healing" and "The Making of JALENAS Herbal Honey Drink." The methods employed included a pre-test to assess participants' understanding of honey and herbal ingredients that support sustainable health, the delivery of educational materials, a hands-on workshop, the distribution of workshop products to participants, and a post-test. Participants then completed a satisfaction questionnaire regarding the seminar, followed by the distribution of certificates and an overall evaluation. The evaluation results showed an improvement in participants' knowledge. Based on the N-Gain score calculation, the majority of participants (73.9%) experienced a moderate improvement, 17.4% experienced a high improvement, and only 2 participants (8.7%) showed no improvement (N-Gain = 0, categorized as low). The average score increased from 73.91 (pre-test) to 87.39 (post-test), indicating a clear improvement in understanding after the seminar. The average N-Gain score of 0.49 indicates a moderate level of effectiveness, meaning that the educational method used was successful but still has room for improvement, and 97% of participants expressed satisfaction with the activities conducted during the workshop.
