Abstract

Digester biogas rumah tangga berpotensi menyediakan bahan bakar terbarukan pengganti LPG (liquefied petroleum gas). Penelitian ini bertujuan untuk merancang-bangun dan menguji kinerja digester biogas rumah tangga tipe tangki mengapung (floating tank) dengan substrat kotoran sapi. Penelitian dilakukan dengan membuat digester biogas tipe floating tank menggunakan sumur dangkal dari pasangan bata semen yang diplester (diameter-dalam 139 cm, kedalaman efektif 140 cm) sebagai digester dan tangki air kapasitas 2000 l sebagai penampung biogas. Ukuran digester didasarkan pada kebutuhan biogas untuk keperluan memasak rumah tangga dan potensi kotoran empat ekor sapi. Kinerja digester dievaluasi dari produksi biogas, komposisi biogas, dan kemampuan digester dalam mendekomposisi substrat yang dinilai dari penurunan kandungan padatan tak stabil (volatile solid, VS). Hasil penelitian menunjukkan bahwa pada suhu lingkungan rata-rata antara 26,97 ℃ (pagi) dan 31,97 ℃ (sore) digester bekerja pada pH rata-rata 7,7 dengan dekomposisi VS mencapai 56,3%. Dengan laju pengumpanan kotoran sapi cair 60 l/hari, produksi biogas dapat mencapai 1.300 l/hari dan produktivitas biogas mencapai 634,6 l/m3 volume aktif digester. Biogas yang dihasilkan memiliki kualitas medium dengan kandungan metana (CH4) mencapai 50,28% dan nilai kalori 18,01 MJ/Nm3. Lumpur digestat berpotensi sebagai pupuk organik dengan kandungan hara N 4,55%; P 2,16%; dan K 3,89%. Salah satu keunggulan yang sangat menonjol dari digester floating tank adalah desain yang sederhana, biaya terjangkau, dan diperkirakan akan awet, sehingga dapat dijadikan sebagai model untuk dikembangkan dan diadopsi.

Abstract

Agricultural waste is widely used as feed or a mixture of feed for livestock. Before use, agricultural waste must be chopped so that livestock can easily eat it. One of the agricultural waste chopping machines is a multipurpose type chopper. The aim of the research was to test the performance of a multipurpose chopper machine for chopping corn cobs and bagasse. This study used a completely randomized factorial design, consisting of 2 factors, namely material (corncob and sugarcane bagasse) and and the rotational speed (RPM) which consists of 600, 800, 1000 and 1360. Each treatment combination was repeated 3 times. Parameters observed were working capacity, weight loss, fuel consumption, specific fuel consumption, and fineness modulus. The results of this study indicate that the work capacity of the bagasse higher than corncob. Working capacity at speeds of 600 RPM to 1000 RPM will increase with increasing speed. Materials and RPM not effect to material loss. fuel consumption and specific fuel consumption of bagasse (0,859 lt/h; 0,074 lt/kg) are higher than corn cobs (0,754 lt/h; 0,170 lt/kg. Fineness modulus of corn cobs is 2.504% and sugarcane bagasse is 2.373%.

Abstract

The development needs of the population that continues to increase cause a mismatch in land use. This can make it possible to reduce water catchment areas in any areas with dense building growth. The use of cement in both housing and road construction results in reduced water absorption areas because cement has properties that make it difficult to absorb water, so water will become stagnant. Therefore, a cement substitute is needed to cover the shortage of cement. The addition of corn cobs in the paving block mortar is expected to increase its water absorption without reducing the compressive strength of the paving blocks. This is done to reduce corn cob waste and save on staple food costs. as well as being used as a useful product innovation in reducing corn cob waste. After printing is complete, the porous paving blocks are dried in the sun and conditioned for approximately 21 days, then the porous paving blocks are ready to be tested. The experimental design consisted of 4 treatments, namely C1, C2, C3, and C4. For the density test, values were obtained with an average of 1.327 g/cm3 – 1.628 g/cm3. For the infiltration test, a value of 0.274 mm/s was obtained. Whereas the visible test is obtained with the appropriate form of paving texture obtained on factor C4 because the resulting texture is good and there are no gaps or defects when the paving has been printed. The highest value from the water absorption test occurred in the C4 treatment with a value of 23.91%. The effect of corncob waste on Porous Paving Blocks in this study is that the more corncob waste fiber is used, the more porous paving block cavities will be, and vice versa if using less corncob waste fiber, the pore cavities will be larger. produced on porous paving blocks will be less. Keywords: Corn Cogs,  Paving block Porous.

Abstract

The multi-purpose animal feed chopping machine is one of the feed chopping tools that many farmers use to help speed up the chopping of raw materials that will be used as animal feed. The chopping machine can be operated optimally if the machine is ergonomic so that it is safe and comfortable to operate. This study aims to analyze the ergonomics of a multi-purpose animal feed chopper in terms of anthropometry, operating workload and the level of work fatigue specifically for the chopper. This research uses quantitative methods which are supported by literature studies regarding the design of creating machine dimensions. The parameters in this study are: (1) anthropometric data consisting of Standing Finger Tip Height (TJUB), Standing Vertical Reach (JVB), and Standing Horizontal Reach (JHB); (2) the recommended weight limit that can be lifted by the operator (RWL), and (3) cardiovascular load (CVL). The research results stated that the height of the chopper hopper (100 cm) was classified as ergonomic because it was still between TJUB (66.10 cm) and JVB (183.95 cm). The operator's position from the hopper should not exceed JHB (66.00 cm). The recommended load limit (RWL) is 5.38 kg. Operation of the machine chopper section does not cause work fatigue with an average CVL of 10.71% (≤ 30%). Keywords: Anthropometry, CVL,  Pulse Rate, RWL, Work Fatigue.
