Abstract

Uji komparasi mesin bakar bervolume 110 cc dengan mesin bakar bervolume 125 cc telah dilakukan. Bahan bakar yang digunakan pada penelitian ini adalah jenis pertamax turbo. Penelitian ini bertujuan untuk mengetahui perbandingan yang terjadi pada mesin bakar bervolume berbeda dengan menggunakan bahan bakar yang sama. Metode yang digunakan adalah menganalisa nilai daya tertinggi pada masing-masing mesin bakar pada putaran mesin. Penelitian ini memberikan hasil bahwa daya terbesar pada masing-masing mesin bakar yang diuji terletak pada putaran 7000 rpm, dengan mencapai 12 hp pada mesin bakar volume 110 cc serta 7,4 hp pada mesin bakar volume 125 cc. Hasil yang diperoleh adalah daya yang dihasilkan pada mesin bakar bervolume 110 cc lebih besar dibandingkan dengan mesin bakar bervolume 125 cc. Hal ini disebabkan volume yang bekerja pada mesin mempengaruhi jumlah beban pembakaran yang terjadi di mesin bakar

Abstract

Tapanrejo Village is located in Muncar Sub-district with a large area and high population density. This village experiences problems with household waste generation, which is dominated by organic waste. This amount of waste is further increased by the presence of agricultural waste which is the result of community activities. Therefore, the solution applied to this problem is to utilize household organic waste which is processed into eco-enzyme liquid. The partners of this activity are mothers from the Tapanrejo Village Family Empowerment and Welfare Movement Team (TP-PKK). The purpose of implementing this program is that partners are able to manage household waste independently and are able to make eco-enzyme liquid with the application of a shred-chopper machine to improve the quality of life of the community. The stages of activity in this program consist of the stages of socialization, mentoring and direct practice. Monitoring and evaluation of the results of community service activities are carried out by assessing the success of participants in making eco-enzyme liquids and distributing questionnaires of satisfaction with the implementation of activities filled in by each participant. This community service activity begins with the implementation of socialization and training in making eco-enzyme liquids, implementing shred-chopper machines for waste shredding, and monitoring the evaluation of activities based on questionnaires filled out by activity participants. The implementation of the activity went well and the women participating in the activity were very enthusiastic about participating in the training from start to finish. Based on the results of the activity, 100% of the participants were able to make eco-enzyme liquid according to the instructions given and based on the satisfaction questionnaire that 80% of the participants were very satisfied with the implementation of socialization and training on household waste management and making eco-enzyme liquid that had been given.

Abstract

Implementasi Unit Pengolahan Sampah (UPS) di kawasan wisata Pantai Pulau Merah, Banyuwangi, bertujuan untuk meningkatkan pengelolaan sampah melalui pemilahan, daur ulang, dan pengomposan. Penelitian ini menganalisis dampak UPS terhadap perubahan timbulan dan komposisi sampah dengan membandingkan data bulanan sebelum (November 2020–Oktober 2021) dan setelah implementasi (November 2021–November 2022). Data diperoleh dari laporan bulanan UPS dan divalidasi melalui wawancara terstruktur. Analisis statistik deskriptif dan inferensial (Independent T-test, uji Chi-square) digunakan untuk menguji signifikansi perubahan. Hasil penelitian menunjukkan peningkatan signifikan volume sampah dari rata-rata 5.298,56 kg/bulan (SD = ±2.092,77) menjadi 13.010,15 kg/bulan (SD = ±6.278,42), diduga akibat perluasan cakupan layanan dan peningkatan kunjungan wisatawan. Komposisi sampah mengalami perubahan dengan dominasi organik meningkat dari 42,1% menjadi 63,2%, residu turun dari 46,3% menjadi 30,5%, dan anorganik daur ulang berkurang dari 11,6% menjadi 6,3%. Temuan ini mengindikasikan efektivitas UPS dalam meningkatkan pemilahan organik dan mengurangi residu, meskipun perlu penguatan sistem daur ulang anorganik. Implikasi penelitian menekankan pentingnya integrasi UPS dengan pendekatan ekonomi sirkular dan edukasi 3R (Reduce, Reuse, Recycle) untuk optimalisasi pengelolaan sampah di kawasan wisata pesisir.
