INTISARIBanyaknya limbah biomassa tongkol jagung yang tidak termanfaatkan sehingga perlu dilakukan sebuah penelitian untuk pemanfaatan limbah tersebut menjadi bahan bakar alternatif briket. Biomassa tongkol jagung zero sulfur dapat digunakan untuk bahan campuran batubara higt sulfur untuk menurunkan kadar sulfur pada briket. Metodologi yang dilakukan melalui empat tahapan, yakni proses pirolisis bahan batubara dan biomassa. Setelah itu proses penggilingan dan pengayakan arang dengan ukuran partikel +50 -120 mesh. Selanjutnya dilakukan pencetakan briket dan yang terakhir tahap pengujian (Uji Proximate, Uji Ultimate, Kecepatan pembakaran). Hasil pengujian yang telah dilakukan diperoleh briket terbaik berdasarkan uji proximate dengan nilai kalor tertinggi pada briket tongkol jagung dengan nilai kalor 6771 kal/gr. Sedangkan perbandingan massa batubara-biomassa yang memenuhi Standar SNI briket yaitu perbandingan 25:75. Berdasarkan uji laju pembakaran briket diketahui jika biomassa mempercepat proses pembakaran.
ABSTRACTThe amount of of waste biomass. Corn cobs that are not utilized so it is necessary to do a research for utilization of waste into alternative fuel. Briquettes zero sulfure corncob biomass can be used to mix higt sulfur coal to reduce sulfur content in briquettes. Methodology carried out through four stages, namely pyrolysis process of coal and biomass materials, after which the proses of grinding amd sieving charcoal with particle size of +50 -120 mesh. Next briquette printing and the last stage of testing (proximate test, ultimate test, burning speed). The result of tests that have been done abtained the best briquettes based one proximate test with the highest calorific value of 6771 cals/gr. While the comparison massage rock bar at biomass which meets the SNI briquette standards that comparison 25:75. Based on briquette burning rate test is known if biomass speed up the combustion process.
The increasing demand for sweet corn (Zea mays, L.) in order to meet community nutrition has encouraged farmers to make improvements to the cultivation system. One of the important factors in the process of increasing sweet corn production is soil nutrients. Peanut shell (Arachys hypogea. L.) and bio-slurry are organic waste, when they have undergone a decomposition process they can be used as organic fertilizers. The aim of the study was to test the correct dosage of peanut shells and the concentration of bio-slurry so that it could be used as organic fertilizer for sweet corn plants. The research was conducted in the experimental garden of the Faculty of Agriculture and Animal Husbandry, University of Muhammadiyah Malang from March to May 2020. It is a factorial experiment arranged in randomized groups, the first factor is peanut shell dose: P1 = 10 tons / ha; P2 = 15 tons / ha; P3 = 20 tons / ha. The second factor is the bio-slurry concentration: B1 = 100 ml/ L; B2 = 125 ml/ L; B3 = 150 ml/ L. The results showed that there was an interaction between the peanut shell dosage treatment and the bio-slurry concentration on the growth and yield of sweet corn. Dose treatment of peanut shells on growth and yield variables of sweet corn is influenced by the concentration of bio-slurry. A combination of suitable treatment for growth and yield to sweet corn is peanut shell dose 15 tons/ ha and bio-slurry concentration 125 ml/ L.
