Hidrolisis Selulosadari Bahan Pod Husk Kakao Menggunakan Asam Klorida

The aims of this experiment were to obtain the best concentration of HCl and the optimum length of boiling time in producing liquid sugar from cacao pod husk. Analysis of data of extracted cellulose (Phase I) used completely randomized design (CRD), which consisted of 3 NaOH concentrations tested namely : 10%, 12% and 14%. Each treatment was replieated 4 times, and therefore there were 12 experimental units used. Analysis of variance showing significant or highly significant effects were subsequently analysed by HSD at 5% or 1%, respectively. Experimental design used in the hydrolysis of cellulose (Phase II) was randomized block design (RBD) with four levels of hydrochloric acid (HCl) tested, namely: K1 = 1%; K2 = 1.5%; K3 = 2% and K4 = 2.5%. Treatments were grouped based on the length of pod husk cellulose hydrolysis time in hydrochloric acid solution, namely R1 = 2 hours, R2 = 4 hours, R3 = 6 hours, R4 = 8 hours, R5 = 10 hours and R6 = 12 hours. Each treatment was replicated three times in each group, and therefore there were 72 experimental units observed. Analysis of variance showing significant or highly significant effects were subsequently analysed by HSD at 5% or 1%, respectively. The best NaOH concentration was obtained at 12% and the optimum length of boiling time was 8 hours

PENGARUH PEMASANGAN RUMPON PADA MUSIM BARAT TERHADAP HASIL TANGKAPAN ALAT TANGKAP PAYANG DI PERAIRAN TUBAN JAWA TIMUR

Nelayan payang di perairan Utara Tuban menggunakan rumpon sebagai alat bantu pengumpul ikan. Rumpon umumnya dipasang pada saat kondisi perairan tenang. Diduga dengan pemasangan rumpon pada saat cuaca buruk (musim barat) produktivitas rumpon akan berbeda. Tujuan dari penelitian ini adalah untuk menghitung dan membandingkan produktivitas alat tangkap payang yang beroperasi di area rumpon yang dipasang saat musim barat dan menghitung produktivitas alat tangkap payang dilokasi rumpon yang berbeda. Penelitian ini menggunakan data sekunder dan data primer. Untuk menghitung dan membandingkan produktivitas alat tangkap payang yang beroperasi di daerah rumpon hasil pemasangan saat musim barat menggunakan rumus CPUE, sedangkan untuk menghitung produktivitas alat tangkap payang dilokasi rumpon yang berbeda menggunakan analisa One Way ANOVA. Perhitungan perbandingan produktivitas alat tangkap payang yang beroperasi di area rumpon yang dipasang saat musim barat menunjukkan peningkatan CPUE dalam jangka pendek(1-3 bulan setelah pemasangan), sedangkan 4-7 bulan berikutnya terjadi penurunan CPUE secara drastis. Produktivitas dilokasi rumpon yang berbeda tidak menunjukkan perbedaan yang signifikan. Disarankan kepada nelayan payang untuk tidak memasang rumpon pada saat musim barat atau jika memasang rumpon saat musim barat perlu pengaturan lebih lanjut agar tidak terjadi eksploitasi berlebihan. Kata Kunci: pemasangan rumpon, musim barat, payang, perairan Tuba
