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

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.

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.

Abstract

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.

Abstract

Biomass energy is produced by converting solid raw materials into a more useful compressed form known as briquettes. This study aims to examine the effect of varying compositions of charcoal briquettes using a mixture of cocoa shells and rice husks on the briquette characteristics. The experimental method employs a Completely Randomized Design with four treatments: P1 = 100% cocoa shells, P2 = 75% cocoa shells + 25% rice husks, P3 = 25% cocoa shells + 75% rice husks, and P4 = 100% rice husks. The study finds that the lowest moisture content is in P3 (8.01%), the lowest ash content is in P3 and P4 (4.1% and 3.8%, respectively), the highest calorific value is in P1 (3,658 cal/g), the longest ignition time is in P3 (50 minutes), and the best hardness is in P2 (785.95 N). Based on the results, the best treatment is P3, which achieves a moisture content of 8.01%, ash content of 4.1%, and the longest burning time of 50 minutes.

Abstract

Demand for melinjo chips is high, but the current production method is less efficient in terms of time. The melinjo flattening machine is a new innovation that has the potential to replace the conventional process, thus optimising post-harvest handling. It is expected that the use of this flattening machine can increase work capacity and facilitate the production of quality melinjo flattening products in the future. This study used experimental methodology with a one-factor completely randomised design (CRD) research design. The experiment consisted of three treatments, namely P1, P2, and P3, with amounts of 1000 grams, 2000 grams, and 3000 grams, respectively. Each treatment was repeated three times, resulting in nine experimental units. Observation data were analysed using the BNJ test at the 5% level to determine which treatment had a significant effect on yield. The test results show that the melinjo seed flattener can operate properly. In testing the capacity of the tool shows the greatest working capacity of the machine, P3, which is 28.73 grams/minute.  The processing time test shows that the treatment that produces the most time is P3 of 88 minutes.  In testing the weight of the flattener results show that P3 produces the most with a value of 2516.67 grams. It is necessary to make improvements to the hopper and redesign by calculating the bulk angle of melinjo seeds, so that melinjo seeds can easily go down to the rationing section. In addition, a stirrer is designed for melinjo seeds that are ready to be flaked with the flattening machine so that when roasting with a stirrer, the melinjo seeds that are still hot are immediately put into the hopper so that they can be flattened using the semi-automatic flattening machine.
