Abstract

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. Keywords: infiltration hole; biopore; biopore compost.

Abstract

ABSTRAKPengabdian Penguatan Ekonomi Perempuan Kepala Keluarga (PEKKA) Berbasis Pemanfaatan Limbah Rumah Tangga Sebagai Ecoenzym Di Desa Sigar Penjalin Lombok Utara. Pengabdian ini dilaksanakan di Desa Sigar Penjalin Kecamatan Tanjung Kabupaten Lombok Utara. Kegiatan pengabdian ini bertujuan untuk meningkatkan pengetahuan mitra mengenai pengolahan sisa-sisa makanan atau sampah rumah tangga menjadi produk yang memiliki nilai tambah dan bernilai ekonomis. 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.

Abstract

One alternative energy that can be used as a substitute for fuel oil and gas is biomass energy such as briquettes. This study aims to determine the amount of heat, moisture content and ash content of briquettes made using hazelnut shells and glutinous rice adhesives that vary in adhesive concentration and particle size. This study used a complete randomised design (CRD) with variations in glutinous rice concentration of 20%, 30%, and 40% while the particle sizes used were 12 mesh and 24 mesh. The results showed that the adhesive concentration did not significantly affect the test parameters while the particle size affected the moisture content, ash content and calorific value of the briquettes. The highest calorific value was obtained by using 24 mesh particle size with 20% adhesive concentration with a calorific value of 5321 cal/g while the 12 mesh particle size produced the highest calorific value of 4704 cal/g at 20% adhesive concentration. The lowest moisture content value was obtained by using 24 mesh particle size with 20% adhesive concentration with a moisture content value of 6.9% while the 12 mesh particle size produced the lowest moisture content value at 20% adhesive concentration with a value of 7.4%. The lowest ash content value was obtained by using 24 mesh particle size with 30% adhesive concentration with an ash content value of 4.99% while the 12 mesh particle size produced an ash content value of 5.82%. The use of 12 mesh particle size is not in accordance with SNI standards because the heating value produced is still below 5000 cal/gr while the use of 24 mesh particle size is in accordance with SNI standards for all test parameters.

Abstract

Stoves are one of the technologies that play an important role in energy utilisation at the household scale. The utilisation of biomass waste as a fuel source is because the waste has a significant energy content. Based on BPS statistics for corn production in 2016, NTB province reached 1,278,271 tonnes and increased in 2017 to reach 2,127,324 tonnes, based on these data it is possible that corn will produce corn cobs that have the potential to be developed into bioethanol and bioenergy. The purpose of this study was to design and build a household scale corn cob waste biomass gasification stove, determine the effect of variations in air flow velocity on room temperature in the combustion process of corn cob waste, determine the comparison of water boiling temperatures at variations in air flow velocity of 5.0 m/s, 10.0 m/s, and 15.0 m/s. The research method used is experimental method by conducting experiments and performance tests in the Agricultural Workshop Laboratory. The research was conducted by varying the speed of air entering the reactor with speed variations of 5.0 m/s, 10.0 m/s and 15.0 m/s. The parameters observed include combustion chamber temperature, water boiling temperature, and initial ignition time. The results showed that the air velocity variation of 15.0 m/s affected the highest combustion temperature with 359.13 with 100 grams of ash, then the highest water boiling temperature was 60℃, and the initial ignition was recorded at 2:20:31 minutes. From the results of this study, it can be said that using the highest speed variation can produce perfect combustion.

Abstract

Compost is an organic fertilizer whose basic ingredients are from weathering plant material or organic waste. However, the community has a few obstacles, namely the need for very large doses of fertilizer which often makes its use difficult. Therefore, efforts need to be made to overcome this problem, namely by making the fertilizer form into a solid form. So a tablet compost printer was made that can determine the capacity of the tool's mold with a press system. Analysis of the data used in this study is a mathematical approach using Microsoft Excel and a statistical approach using ANOVA diversity analysis and further test of Honest Significant Difference (BNJ) level 5%. The results showed that the higher the addition of hydrogel, the lower the dimension value, both weight, height and diameter of the tablet. The capacity of the mold in each treatment was carried out 3 times the average repetition of each treatment at P1 4.41 kg/hour, P2 6.10 kg/hour and P3 6.30 kg/hour the weight of the compost material affects the capacity of the mold, the heavier the material being printed, the higher the capacity of the mold.

In areas where maize is the main commodity, maize waste such as husks and cobs are often neglected. In West Lombok Regency, maize is an important commodity with a yield of 77,304 tonnes in 2023. However, corn waste has not been optimally utilised. This community service programme aims to teach residents of Mesanggok Village to process corncob waste into briquettes, as an environmentally friendly alternative fuel. The method used in this activity is socialisation which includes lectures, discussions, and video screenings, followed by pretests and posttests to evaluate the increase in participants' knowledge. The results of the activity showed an increase in participants' knowledge from 43% to 92%, with statistical test results using a significant paired sample T test. This socialisation not only increased knowledge but also opened participants' insights into new business opportunities through the production of briquettes from corn waste, supporting the West Nusa Tenggara Provincial Government's zero waste programme, and contributing to efforts to improve the economic welfare of the local community. Keywords: biomass waste; briquettes; energy; maize cobs.

Abstract

The energy crisis is increasingly felt starting from the scarcity of petroleum and gas fuels plus the increasingly expensive price makes it necessary to make efforts to obtain alternative renewable energy. One of the biomass materials that can be used as briquettes is hazelnut shells because in some observations in the field hazelnut shells tend to be discarded after taking the meat. The purpose of this study was to determine the differences in the characteristics of briquettes produced such as moisture content, calorific value, ash content influenced by the type of adhesive derived from glutinous rice so as to obtain the ideal formulation for making briquettes from hazelnut shells. This study used a complete randomised design (CRD) with variations in glutinous rice flour concentration of 20%, 30%, and 40%. The results showed that the concentration of the adhesive used was not significantly different from the value of water content, ash content and calorific value produced. The best quality briquettes were at 40% adhesive percentage, with a calorific value of 5321 cal/gr, 7.2% moisture content, and 5.1% ash content. Pecan shell briquettes with rice flour adhesive are in accordance with the Indonesian national standard (SNI) both from the value of water content, ash content and calorific value.

Abstract

Groundnut production in West Nusa Tenggara Province has increased every year. Post-harvest handling of peanuts at the farm level is generally still done traditionally, especially when harvesting, threshing pods or stripping the peel, which requires a lot of labour. This study aims to determine the effect of peanut pod diameter on each parameter, tool efficiency, and tool production quality. The method used in this research is the experimental method by conducting experiments directly in the laboratory. The parameters observed in this study are the efficiency of the tool, the need for electrical power, and the quality of peanut seed stripping. The analysis results showed that each treatment with different diameters had no significant effect on each parameter observed. The stripping quality of the three treatments has not met the standard.
