Rice quaker are traditional food from the Sambas regency. The manufacture of rice quaker has been traditionally done by pounding it. Economically, the production capacity of traditionally made rice quaker is so low that it needs to be increased by changing the manual to mechanical flattening system. The purpose of this research is designing a prototype machine for flattening rice quaker as well as conducting experimental studies on the flattening process. The research stages were to design, manufacture, and test the performance of the flattening rice quaker. The independent variables of the study were the gap width and the number of flattening, while the dependent variables of the study were thickness and percentage damage of rice quaker. The width of the gap was varied into 0.4 mm, 0.6 mm, 0.8 mm, and 1.0 mm, while the number of flattening was varied to 1, 2, and 3 times the flattening. The result of the construction of the prototype rice quaker machine is in accordance with the initial design, and can work to flatten rice quaker. The engine test was carried out at a flat roller speed of 360 rpm. The thickness of the rice quaker made traditionally, 0.98 mm, can be approached by flattening using a machine at a gap width of 0.8 mm with 2 flakes resulting in a thickness of 0.96 mm quaker with a percentage of damage of 38.52%. In general, the level of damage to the resulting rice quaker is still very high, so further analysis is needed.Keywords: Rice quaker, gap width, flattening machine, flat rollers.

Lada hitam dihasilkan dari buah tanaman lada yang diproses dengan cara dirontok dan dikeringkan. Proses perontokan dapat dilakukan secara manual atau mekanis. Proses perontokan lada secara manual memiliki banyak kelemahan sehingga perlu dikembangkan sistem perontokan lada secara mekanis. Sistem perontokan yang didesain harus sesuai dengan kebutuhan petani lada yang umumnya adalah petani dengan luas lahan sempit. Mesin perontok lada tipe silinder perontok berjaring merupakan upaya untuk mengatasi permasalahan ini karena mesin memiliki konstruksi sederhana, murah dan terbuat dari bahan yang mudah diperoleh. Tujuan penelitian yang dilakukan adalah merancang bangun dan menguji kinerja mesin perontok lada dengan mekanisme perontok berupa silinder perontok berjaring. Variabel bebas dalam pengujian adalah kekuatan tarik pegas sedangkan variabel tak bebas adalah kapasitas, efisiensi perontokan dan tingkat kerusakan buah lada. Pelaksanaan penelitian dilakukan dengan melakukan perancangan dan pembuatan komponen, dilanjutkan dengan melakukan pengujian. Hasil rancang bangun diperoleh mesin perontok lada tipe silinder perontok berjaring berpenggerak motor listrik 1/4 HP, kecepatan putar silinder perontok 339 rpm, sistem transmisi sabuk V dan puli, massa mesin 12 kg, panjang 50,0 cm, lebar 38,5 cm dan tinggi 68 cm.

Untuk memberikan perlindungan tenaga kerja dari kecelakaan dan penyakit akibat kerja, maka perusahaan haruslah terlebih dahulu memahami resiko dan potensi bahaya yang ada pada pekerjaan yang mereka jalankan. Potensi bahaya merupakan suatu potensi untuk terjadinya insiden yang berakibat kerugian sedangkan risiko adalah kombinasi dan konsekuensi suatu kejadian berbahaya dan peluang terjadinya kejadian tersebut (ILO). Menurut Direktur Pelayanan BPJS Ketenagakerjaan Krishna Syarif dalam finance.detik.com "Sepanjang 2017, menurut statistik kami terjadi peningkatan kecelakaan kerja sekira 20 persen dibandingkan 2016 secara nasional". Total kecelakaan kerja pada 2017 sebanyak 123 ribu kasus dengan nilai klaim Rp 971 miliar lebih. Angka ini meningkat dari tahun 2016 dengan nilai klaim hanya Rp 792 miliar lebih. Sedangkan menurut Kepala Badan Penyelenggara Jaminan Sosial (BPJS) Ketenagakerjaan Kantor Cabang Pontianak Ady Hendratta dalam Tribun Pontianak menerangkan “Angka kecelakaan kerja sepanjang Januari 2018 sebanyak 99 kasus di Kalimantan Barat. Ada 99 kasus kecelakaan kerja yang didominasi oleh perkebunan sawit. Persentasenya 40 persen". Dari data kecelakaan kerja tersebut, maka dapat dihitung bahwa 40% dari 99 kasus yang terjadi sebanyak 40 kasus kecelakaan kerja terjadi di perusahaan perkebunan sawit di Kalimantan Barat dalam tempo 1 bulan. Berdasarkan hal tersebut di atas maka penulis tertarik untuk membahas tentang Analisa Resiko Keselamatan dan Kecelakaan Kerja di PT. X yang merupakan perusahaan yang bergerak di bidang Perkebunan dan Pengolahan Sawit. Dari hasil analisa disimpulkan bahwa resiko keselamatan dan kesehatan kerja yang paling dominan adalah pekerjaan yang berhubungan dengan bahan kimia seperti pupuk, pestisida / herbisida, insektisida. Pekerjaan yang berhubungan dengan bahan kimia, jika syarat alat pelindung diri dipenuhi dan ditaati kemungkinan untuk terjadi kecelakaan memang kecil, tetapi hal ini berpotensi menimbulkan penyakit akibat kerja, karena efek dari bahan kimia tersebut adalah efek jangka panjang.

The purpose of this study was to determine the effect of solar panel circuits on current, voltage and power. This research is a true experiment. Dependent variables were current, voltage, and power. Independent variables were a series circuit of solar panels and a parallel circuit of solar panels. The sample numbers of studies were 12 for each group of independent variables. The data were analyzed using the t-test at the 5% signification level. The results showed that the electrical power produced by a series circuit of solar panels was, P = 4.81 watt, Sd = 0.24. The electrical power produced by a parallel circuit of solar panels was P = 4.69 watts, Sd = 0.13. The t-test showed that there was no difference in electrical power produced by the series circuit of solar panels and parallel circuit of solar panels, with to = 1.525 < tα/2, v =2,074. The form of a circuit (series or parallel) has no significant effect on power but differs only in current and voltage. In series circuit, I1 = I2 = IΣ and V1 +V2 = VΣ. In parallel circuits V1 = V2 = VΣ and I1 + I2 = IΣ. This can be adjusted to our purpose of using solar panels circuit. If it requires a large current, the solar panels must assemble in a parallel circuit. But if it requires a large voltage, the solar panels must assemble in a series circuit.Keywords: current, parallel, power, series, voltage
