Abstract

Bekas limbah dari proses pemrosesan tebu dan kulit singkong merupakan sumber yang berpotensi dimanfaatkan. Menggunakan bahan-bahan ini untuk menciptakan briket adalah solusi cerdas dalam memproduksi bahan bakar alternatif. Batu bara dan minyak, dua sumber energi utama saat ini, semakin menipis cadangannya. Oleh karena itu, penting bagi kita untuk mencari sumber energi terbarukan, seperti briket, yang dapat diperbarui secara berkelanjutan. Penelitian yang dilakukan menggunakan ampas tebu dan kulit singkong sebagai bahan baku, yang diikat dengan tepung tapioka dalam tiga rasio berbeda: 70/55/15, 60/60/15, dan 55/70/15 gram. Hasil penelitian menunjukkan bahwa nilai kalor terendah ditemukan pada komposisi briket 60/60/15 dengan hasil 3.75 kal/gr, sementara laju pembakaran tertinggi dicapai oleh komposisi 70/55/15 dengan hasil 4.67 kal/gr. Laju pembakaran terendah diukur pada komposisi 70/55/15 dengan hasil 7.63 gram/menit, sedangkan laju pembakaran tertinggi tercatat pada komposisi 55/70/15 dengan hasil 8.06 gram/menit. Kandungan air paling rendah terdapat pada komposisi 70/55/15 dengan hasil 14.6%, sementara kadar air pembakaran tertinggi terdapat pada komposisi 60/60/15 dengan hasil 30.5%.

Abstract

Tidak semua alat rehabilitasi dapat digunakan oleh pasien pascastroke yang baru saja sembuh dari serangan stroke bahkan mereka belum dianjurkan menggunakan media rehabilitasi dan hanya melakukan terapi dengan gerakan-gerakan sederhana dikarenakan keseimbangan tubuh mereka belum baik, kurangnya koordinasi anggota gerak tubuh, memiliki kelemahan otot dan masih memerlukan alat bantu gerak seperti tongkat dan kursi roda. Tujuan dari penelitian adalah merancang sepeda roda tiga tanpa pedal yang didesain sesuai kebutuhan pasien pasca stroke untuk proses rehabilitasi. Metode yang dilakukan adalah membuat pemodelan tiga dimensi dan dilakukan simulasi secara numerik dengan metode elemen hingga. Hasil perancangan adalah sepeda ini dirancang dengan ground clearance 153 mm agar pasien pasca stroke mampu mengangkat kakinya. Pasien dapat mengendarai sepeda dengan mengayunkan kaki selayaknya berjalan untuk melatih anggota gerak bawah seperti paha, lutut, dan kaki. Hasil simulasi metode elemen hingga pada rangka sepeda menunjukkan bahwa terjadinya tegangan maksimum sebesar 38,806 Mpa pada daerah sambungan seat tube dan down tube serta deformasi maksimum terjadi pada daerah sadel yaitu 0.399 mm. Berdasarkan analisa ergonomis, sepeda ini memiliki kenyamanan dan mampu meminimalisir adanya risiko cidera baik saat dikendarai di jalan lurus maupun berbelok.

Abstract

The purpose of this study was to evaluate the implementation of Qanuns (local regulations) for controlling productive cattle and buffalo in Aceh Besar District. This study conducted a census of abattoir officers to 10 respondents and 10 muge (intermediaries) to collect data on the population in this study involving all groups of cattle and buffalo farmers in Aceh Besar district, namely 627. The number of samples was determined based on the Slovin formula, i.e., 93 farmers with a 5% error rate. Also, a survey was conducted on six sub-districts in Aceh Regency based on a cluster sampling system. Data processing was done by calculating the percentage of measured parameters and presented in tabular form. The results of the study indicated that the implementation of Qanun decreased the slaughter of productive female cattle and buffalo in Aceh Besar District. However, public understanding of the control of productive female cows/buffalo Qanun remained low because only 30.98% of the public were aware of the Qanun. The lack of knowledge was indicated by the high slaughter and sales of productive female cattle and buffalo at the farmer level that only decreased by around 5.84% (from 70.88% to 65.04% after the implementation of Qanun. Economic needs were the reason for the high sales of productive female cows/buffaloes (73.13%). The weak implementation of Qanun on productive cattle and buffalo was probably due to poor socialization of Qanun for controlling productive cattle and buffaloes. 79.65% of the respondent group answered that they had never received socialization on controlling productive female cattle and buffalo. However, the contributing factors to the declining slaughter and sales of productive female cattle and buffalo since the introduction of Qanun were the strict regulations at the abattoir and the level of knowledge of the abattoir staff regarding Qanun to maintain productive cattle and buffaloes.
