Abstract

Program Bumi Sejuta Sapi (BSS) merupakan upaya Pemerintah Provinsi NTB dimulai dari tahun 2008 sampai dengan tahun 2018 bagai dua sisi mata uang dimana dapat memberikan dampak positif di satu sisi tetapi juga dampak negatif di sisi lain. Masyarakat Desa Andalan Kecamatan Bayan Kabupaten Lombok Barat salah satunya yang terkena dampak negatif dari program tersebut, 80-85% penduduknya memiliki ternak namun limbahnya (kotoran) pada musim penghujan selalu menyebabkan bau menyengat dikarenakan letak kandangnya berdekatan dengan pemukiman warga. Hal ini juga menyebabkan kasus kesehatan penyakit saluran pernapasan memasuki musim penghujan.  Tujuan dari pendampingan ini adalah untuk memberikan solusi alternatif dengan membangun instalasi digister bagi masyarakat dan memberikan pendampingan untuk pengoperasian dan pemeliharaan instalasi digister yang dibangun di Desa Mitra Kegiatan yakni Desa Andalan Pelatihan pengoperasian, pemeliharaan Digister dan mengukur tingkat kapuasan masyarakat terhadap keberadaan instalasi digister yang dibangunkan merupakan metode yang digunakan. Pengukuran dengan uji T-test taraf 5%. Pembangunan instalasi digister menjadi biogas mengurangi jumlah kasus penyakit saluran pernapasan (Puskesmas Pembantu Desa Andalan). Sebelum pembangunan terdapat 27 kasus dan setelah baru terdapat 3 kasus. Kepuasan terhadap pembangunan instalasi biogas menunjukkan bahwa 93% masyarakatnya sangat puas dengan pembangunan tersebut dan menilai sangat nyata hasilnya serta mampu menghemat pengeluaran untuk membeli gas LPG.

Desa Andalan memiliki sumber daya pertanian dan peternakan yang dapat dimanfaatkan untuk pembuatan pupuk organik guna mengatasi kelangkaan pupuk subsidi. Tujuan dari kegiatan pengabdian ini adalah meningkatkan pengetahuan kelompok tani dan ternak tentang manfaat, cara pengelolaan dan teknik pembuatan pupuk organik yang berbahan kotoran sapi yang selama ini menjadi limbah di masyarakat. Metode yang digunakan adalah penyuluhan berupa ceramah, diskusi, dan demonstrasi menggunakan video tentang penggunaan dan pembuatan pupuk organik. Selain itu untuk mengetahui peningktan pengetahuan peserta digunakan pretest dan post test. Kegiatan penyuluhan telah dilaksanakan Balai Dusun, Dusun Gelumpang, Desa Andalan, Kecamatan Bayan, Kabupaten Lombok Utara. Hasil kegiatan menunjukkan bahwa peserta sangat antusias mengikuti kegiatan dimulai dengan jumlah peserta yang hadir, serta pertanyaan yang aktiv saat sesi diskusi. Berdasarkan hasil analisa pretest dan posttest menggunakan uji paired sample T-test diketahui bahwa terjadi peningkatan pengetahuan yang signifikan dengan nilai signifikasi (2-tailed)  yang artinya terdapat pengaruh yang bermakna terhadap pengetahuan peserta sebelum dan sesudah penyuluhan. Peningkatan pengetahuan naik sebesar 36.72% sesudah dilakukannya kegiatan penyuluhan dari sebelumnya 60.280. menjadi 97.00. Adanya kegiatan ini menambah wawasan peserta mengenai pupuk organik ini sehingga dapat mengurangi ketergantungan penggunaan pupuk an-organik. Para peserta berharap kedepannya aka nada pelatihan pembuatan pupuk organik sehingga para peserta yang merupakan petani dan peternak ini bisa langsung memahami tahap-tahapnya. Kata kunci: limbah organik; penyuluhan; pupuk organik. ABSTRACTMany people in Andalan Village complain about the availability of chemical fertilisers such as Urea Fertiliser, TSP Fertiliser, ZA Fertiliser and others which are often limited and scarce, especially during the rainy season. Andalan Village has agricultural and livestock resources that can be used to make organic fertiliser to overcome the scarcity of subsidised fertiliser. The purpose of this service activity is to increase the knowledge of farmer and livestock groups about the benefits, management methods and techniques for making organic fertiliser made from cow dung which has been a waste in the community. The method used is counselling in the form of lectures, discussions, and demonstrations using videos on the use and manufacture of organic fertiliser. In addition, to determine the increase in knowledge of participants, pretest and post test were used. Extension activities have been carried out at the Hamlet Hall, Gelumpang Hamlet, Andalan Village, Bayan District, North Lombok Regency. The results of the activity showed that the participants were very enthusiastic about participating in the activity starting with the number of participants who attended, as well as active questions during the discussion session. Based on the results of pretest and posttest analysis using paired sample T-test, it is known that there is a significant increase in knowledge with a significance value (2-tailed) p=0.000 <0.05, which means that there is a significant influence on the knowledge of participants before and after counseling. The increase in knowledge increased by 36.72% after the extension activities from the previous 60.280 to 97.00. The existence of this activity adds to the participants' insight into this organic fertiliser so that it can reduce dependence on the use of inorganic fertilisers. The participants hope that in the future there will be training in making organic fertiliser so that the participants who are farmers and breeders can immediately understand the stages. Keywords: extension; organic fertilizer; organic waste.

Abstract

Agricultural biomass such as cocoa husks and peanut shells have great potential as raw materials for briquettes to support the provision of sustainable alternative energy. This study aims to evaluate the effect of variations in the composition of these two materials on the characteristics of briquettes, including calorific value, moisture content, ash content, and burning time. The study was conducted using a completely randomized design (CRD) with five treatment compositions (KC1=100:0, KC2=70:30, KC3=50:50, KC4=30:70, KC5=0:100) and three replications. Data were analyzed using Analysis of Variance (ANOVA), and if significant effects were found, the analysis was continued with Duncan’s Multiple Range Test (DMRT) at the 5% level. The results showed that a high proportion of cocoa husk resulted in higher moisture content (15.78%) and lower calorific value (3867 kcal/g), while a high proportion of peanut husk increased the calorific value to 5340 kcal/g and burning time to 84.8 minutes, but was accompanied by higher ash content (17.57%). The balanced mixture of KC3 (50:50) and KC4 (30:70) proved to offer the best compromise, with moisture content <10%, calorific value >4400 kcal/g, burning time >78 minutes, and ash content still within an acceptable range. Thus, although pure peanut shell briquettes (KC5) offer the highest performance, the combination of KC3 and KC4 is more worthy of consideration for improving briquette quality while optimizing the utilization of abundant cocoa shell waste.

Abstract

Abstrak. Penggilingan gabah merupakan proses pengolahan gabah kering menjadi beras dengan bantuan mesin yang dikontrol penuh oleh pekerja pada stasiun tertentu. Manusia sebagai pekerja tengah berada pada ruang penggilingan dengan banyak resiko seperti bising dan getaran yang ditimbulkan oleh mesin tersebut dan antropometri yang belum terjamin kesesuaiannya dengan pekerja yang mengoperasikan mesin tersebut sehingga perlu dikaji berdasarkan kajian ergonomika. Penelitian bertujuan untuk menganalisa antropometri mesin dengan pekerja serta lingkungan fisik untuk mengurangi resiko kerja. Metode penelitian menggunakan metode eksperimental yang dikaji langsung pada ruang penggilingan beras di Desa Batu Putik Lombok Timur. Parameter yang dikaji yaitu antropometri, tingkat kebisingan, getaran mekanis, suhu dan tingkat pencahayaan. Data hasil penelitian dianlisis menggunakan matematika sederhana dengan bantuan mikrosoft excel kemudian dibandingankan dengan Nilai Ambang Batas (NAB) pada setiap parameter. Hasil penelitian menunjukkan bahwa antropometri pada 3 stasiun yang dikaji yaitu stasiun pertama tempat gabah dimasukkan berada 200 cm artinya hopper tersebut berada di atas kepala operator, stasiun kedua output gabah pecah 50% memiliki ketinggian 92 cm dan stasiun ketiga yaitu output beras bersih siap untuk dikemas memiliki tinggi 92 cm. Sedangkan hasil analisis dari lingkungan fisik menunjukkan bahwa suhu di atas NAB dan pecahayaan di bawah NAB, sedangkan getaran mekanis dan tingkat kebisingan berada di atas Nilai Ambang Batas NAB. Sehingga dapat disimpulkan bahwa ruang produksi penggilingan gabah dapat dikatakan belum memenuhi standar ergonomika.Anthropometric and Physical Environmental Analysis of Grain Milling Rooms to Reduce Work RisksAbstract. Grain milling is the process of processing dry grain into rice with the help of machines that are fully controlled by workers at certain stations. Humans as workers are in the milling room with many risks such as noise and vibrations caused by the machine and anthropometers that are not yet guaranteed to be suitable for the workers operating the machine so this needs to be studied based on ergonomics studies. The research aims to analyze the anthropometry of machines and workers and the physical environment to reduce work risks. The research method used experimental methods which were studied directly in the rice milling room in Batu Putik Village, East Lombok. The parameters studied are anthropometry, noise level, mechanical vibration, temperature and lighting level. The research data was analyzed using simple mathematics with the help of Microsoft Excel and then compared with the threshold value (NAB) for each parameter. The results of the research show that the anthropometry at the 3 stations studied, namely the first station where the grain is inserted is 2 meters, meaning the hopper is above the operator's head, the second station, the output of 50% broken grain has a height of 92 cm and the third station, namely the output of clean rice ready to be packaged, has a height of 92 cm. cm. Meanwhile, the results of analysis of the physical environment show that the temperature is above NAB and lighting is below NAB, while mechanical vibrations and noise levels are above the threshold value NAB. So it can be concluded that the grain milling production room can be said to not meet ergonomic standard.

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

Agricultural wastes such as cocoa shells and groundnut shells hold significant potential as environmentally friendly alternative energy sources, particularly in West Nusa Tenggara Province, where these commodities are produced in abundance. However, their utilization as biomass energy materials remains limited and underdeveloped. In response to this potential, this study aims to evaluate the effect of varying tapioca starch adhesive concentrations on the characteristics of briquettes made from a mixture of cocoa shell charcoal and peanut shells. The research was conducted experimentally using three adhesive concentrations (10%, 20%, and 30%), with tests performed on calorific value, moisture content, ash content, and flame duration. The results revealed that increasing the adhesive concentration tended to decrease the calorific value and increase both the moisture and ash contents, although it extended the flame duration. The briquettes with 10% adhesive concentration exhibited the best performance, achieving a calorific value of 5,310 cal/g, a moisture content of 7.57%, an ash content of 7.56%, and a flame duration of 73 minutes. These values comply with the Indonesian National Standard (SNI) for charcoal briquettes, which require a minimum calorific value of 5,000 cal/g, a maximum moisture content of 8%, and a maximum ash content of 8%. These findings highlight the importance of proper adhesive formulation to improve the quality of local biomass-based briquettes and support the transition toward clean and sustainable energy..
