ABSTRAKKepadatan penduduk di wilayah perkotaan akan menimbulkan masalah-masalah sosial perkotaan seperti : terbatasnya area pekarangan, ruang interaksi yang kurang, dan genangan air pada saat hujan. Curah hujan tertinggi di Kecamatan Sekarbela terjadi pada bulan Januari hingga Maret dengan rata-rata 323-338 mm, hal ini cenderung membuat genangan di beberapa titik termasuk di wilayah lingkungan Bagek Kembar. Tujuan pengabdian ini adalah untuk membantu warga lingkungan Bagek Kembar mengurangi genangan air hujan, yaitu dengan membuat lubang resapan sederhana yang umum dikenal dengan lubang biopori. Metode yang digunakan dalam kegiatan ini adalah sosialisasi dan pelatihan pembuatan secara langsung. Sosialisasi di sini adalah memberikan ilmu dan pengetahuan kepada mitra mengenai apa itu lubang biopori, apa manfaat, dan bagaimana proses pembuatannya. Sosialisasi dilakukan dengan “door to door” mendatangi tiap rumah yang dipilih sebagai titik penggalian lubang biopori, dengan unsur yang terlibat adalah dosen, mahasiswa, karyawan, dan warga (mitra). Hasilnya adalah warga memiliki 2 sampai 3 lubang biopori dan menjadi faham tentang manfaat dan kegunaan dari lubang tersebut. Evaluasi dilakukan secara berkala, selang 3 bulan pasca pembuatan. Kata kunci: lubang resapan; biopori; kompos biopori. ABSTRACTPopulation density in urban areas will cause urban social problems such as: limited yard areas, less interaction space, and stagnant water when it rains. The highest rainfall in Sekarbela District occurs from January to March with an average of 323-338 mm, this tends to cause puddles at several points including in the Bagek Kembar neighborhood area. The purpose of this service is to help residents of the Bagek Kembar neighborhood reduce rainwater stagnation, namely by making a simple infiltration hole commonly known as a biopore hole. The method used in this activity is socialization and direct manufacturing training. The socialization here is to provide knowledge and knowledge to partners about what biopori holes are, what are the benefits, and how the process is made. The socialization was carried out by "door to door" visiting each house chosen as the point for digging the biopore holes, with the elements involved being lecturers, students, employees, and residents (partners). The result is that residents have 2 to 3 biopori holes and become aware of the benefits and uses of these holes. Evaluation is carried out periodically, 3 months after manufacture.

Selain itu, produk yang dihasilkan dari pengolahan limbah tersebut juga dapat memberikan sumbangan pendapatan dalam perekonomian mitra. Pelaksanaan kegiatan pengabdian dilakukan dengan dua metode yaitu metode pelatihan dan pendampingan dengan pemberian pre test sebelum kegiatan pelatihan dimulai dan post test setelah kegiatan pelatihan selesai. Pelatihan dan pendampingan dilakukan dengan praktek pembuatan ecoenzym oleh anggota mitra dengan pendampingan oleh tim pelaksana kegiatan hingga ecoenzym dapat dipanen, yaitu selama 3 bulan. Hasil kegiatan menunjukkan bahwa anggota mitra umumnya langsung membuang sampah rumah tangga tanpa diolah yaitu sebesar 76%. Hasil pelatihan pembuatan ecoenzym menunjukkan terjadi peningkatan pemahaman anggota mitra mengenai ecoenzym sebesar 16% dibandingkan sebelum dilaksanakan kegiatan pelatihan, anggota mitra yang tidak mengetahui tentang ecoenzyme adalah 84%. Hal ini menunjukkan rendahnya pengetahuan dan pemahaman bahwa sampah dapat diolah menjadi produk yang bernilai ekonomis sehingga dapat menjadi salah satu sumber pendapatan yang pada akhirnya akan meningkatkan kesejahteraan dan kualitas hidup . Kegiatan pengabdian ini akan berlangsung selama 4 bulan sejak awal persiapan kegiatan hingga produk ecoenzym dapat dipanen. Kata kunci: ekoenzym; Limbah rumah tangga; PEKKA. ABSTRACTEconomic Strengthening Service for Women-Headed Households (PEKKA) Based on the Utilization of Household Waste as Ecoenzymes in Sigar Penjalin Village, North Lombok. This service was carried out in Sigar Penjalin Village, Tanjung District, North Lombok Regency. This service activity aims to increase partners' knowledge about processing food or household waste into products that have added value and economic value. In addition, the products produced from processing this waste can also contribute to the income of the partner's economy. The implementation of community service activities is carried out using two methods, namely training and mentoring methods by giving a pre-test before the training activities begin and a post-test after the training activities are completed. Training and mentoring are carried out by practising making eco enzymes by partner members with assistance from the activity implementation team until the eco enzymes can be harvested, which is for 3 months. The results of the activity show that partner members generally directly dispose of household waste without processing, which is 76%. The results of the training on making eco enzymes showed an increase in partner members' understanding of ecoenzymes by 16% compared to before the training activities were carried out, partner members who did not know about ecoenzymes were 84%. This shows the low knowledge and understanding that waste can be processed into economically valuable products so that it can become a source of income which will ultimately improve welfare and quality of life. This service activity will last for 4 months from the beginning of the preparation of activities until the eco enzyme products can be harvested. Keywords: ecoenzyme; Household waste; PEKKA.

Sampah merupakan barang yang dianggap sudah tidak terpakai dan dibuang oleh pemilik/pemakai sebelumnya, namun dalam kondisi dan pengolahan tertentu sampah masih dapat digunakan. Contohnya adalah sampah organik, sampah organik adalah sampah yang bisa mengalami pelapukan (dekomposisi) dan terurai menjadi bahan yang lebih kecil dan tidak berbau (kompos). Sampah organik biasanya berasal dari makhluk hidup, baik manusia, hewan maupun tumbuhan, sampah organik sendiri dibagi menjadi dua, yaitu : Sampah organik basah dimana sampah mempunyai kandungan air yang cukup tinggi dan Sampah organik kering, biasanya sampah ini dari bahan yang kandungan airnya kecil. Sampah organik memiliki banyak manfaat salah satunya adalah sebagai penyubur tanah dan pupuk organik. Namun masih banyak masyarakat dan petani yang tidak tahu manfaat dari sampah organic dan cara mengolah sampah organik, padahal pengetahuan tentang teknik pengolahan sampah organik sangat diperlukan agar masyarakat dapat mengetahui dan mempraktikkan secara langsung teknik pengolahan sampah yang baik dan benar, oleh karena itu melalui pengabdian ini diharapkan masyarakat dan petani dapat memiliki tambahan pengetahuan tentang bagaimana cara memisahkan sampah berdasarkan jenisnya dan teknik mengolah sampah organik menjadi pupuk organik.

Abstract: Biogas is a renewable energy source. Biogas can be produced from agricultural waste and industrial waste. One of the alternatives to handling tofu industry waste that currently has a lot to be developed is to convert industrial waste into alternative fuel in the form of biogas. This study aims to determine the effect of the addition of tofu liquid waste on changes in temperature, pH, volume and pressure that occur during the formation of biogas. This research was conducted from July to August for 22 days. The method used in this research is the experimental method by conducting direct experiments. The design used in this study was a one-factor Completely Randomised Design (CRD), consisting of P0 with rice straw + 4 litres of water, P1 with the addition of 20% tofu liquid waste, P2 with 40%, P3 with 60%, P4 with 80% and P5 with 100%. Observation data were analysed with Analysis of Variance at the 5% level. The parameters observed in the study were temperature, pH, volume and pressure. Based on the results of the analysis that has been done, the lowest temperature was obtained in the P3 treatment at 27.39 ° C, while the highest temperature was obtained in the P2 treatment at 27.86 ° C. The lowest pH was obtained in the P5 treatment at 4.24, while the highest pH was obtained in the P1 treatment at 4.57. The lowest volume was obtained in the P1 treatment at 0.00000011513 m3, while the highest volume was obtained in the P0 treatment at 0.00000161291m3, the lowest pressure was obtained in the P3 treatment at 109.08 N/m2, while the highest pressure was obtained in the P2 treatment at 109.25 N/m2. Therefore, it can be concluded that the addition of tofu waste to rice straw does not significantly affect the formation of biogas produced.

This research aims to design and build an alcohol distillation machine made from duku fruit using a refrigerator cooling system and a box cooler as a condenser. The distillation machine utilizes a heating furnace to produce ethanol vapor from fermentation, which is then condensed in a cooled box cooler. Tests were conducted with variations in furnace temperature (110°C, 125°C, 140°C, and 155°C). The results show that the higher the heating temperature, the volume of distillate produced increases, from ±132 ml to ±330 ml. However, the ethanol content remained relatively low (10-20%) due to the low initial ethanol content of the fermentation and only one-stage distillation. These results show that the design of the device can function well on a laboratory scale, although further distillation is needed to increase the ethanol content. This research is expected to be the first step in developing a small-scale ethanol distillation device that is efficient and easy to implement.
