Abstract

Abstrak. Pembibitan menggunakan polybag dapat digantikan dengan biopot yang dapat langsung ditanam bersama bibit saat transplanting, sehingga tidak merusak perakaran, serta baik untuk adaptasi bibit di lingkungan yang baru. Penelitian ini bertujuan untuk melakukan optimalisasi komposisi pada pembuatan biopot berbahan dasar ampas kelapa untuk meningkatkan sifat fisik–mekanik biopot serta pertumbuhan bibit cabai. Rancangan percobaan pada penelitian ini berupa Rancangan Acak Lengkap (RAL). Terdapat 4 perlakuan perbandingan massa bahan ampas kelapa dan lem sagu, yaitu AK-A (1 : 1); AK-B (1 : 1,25); AK-C (1 : 1,5); serta AK-D (1 : 1,75). Pengamatan yang dilakukan berupa sifat fisik-mekanik biopot serta pertumbuhan bibit. Hasil penelitian menunjukkan bahwa perlakuan memberikan pengaruh terhadap sifat fisik-mekanik biopot. Hasil uji Duncan menunjukkan perlakuan AK-D adalah perlakuan dengan bobot, densitas, dan kemampuan menahan gaya luar tertinggi, serta yang paling rendah indeks penyerapan air dan kadar air biopotnya. Hasil ini mengkonfirmasi bahwa perlakuan AK-D merupakan perlakuan terbaik ditinjau dari sifat fisik-mekanik biopot yang dihasilkan. Perlakuan AK-D menghasilkan bobot, densitas, dan kemampuan menahan gaya luar tertinggi, masing-masing sebesar 70,33 g; 500,41 kg/m3; dan 138,33 N, dengan kadar air dan daya serap air terendah yaitu 11,51% basis basah dan 52,89%. Adapun parameter pertumbuhan tanaman tidak berpengaruh nyata untuk tiap perlakuan Kata Kunci: Bibit, Biopot, Organik, Polybag, Sagu

Abstract

Abstract. This study aims to examine the potential of AC condenser wasted heat and compare the actual potential possessed by AC condenser wasted heat as a heating source for dryers, with its use in turmeric drying. There are two stages of testing carried out, namely testing on dryers without materials, and testing with turmeric. The no-load drying test aims to see the temperature range of the wasted heat of an AC condenser in filling a cabinet dryer. Whereas the testing with sliced turmeric aims to see the performance of the heating source in drying the material. This research was conducted by measuring the temperature of the AC condenser output in the channel between the condenser and the dryer, the plenum chamber, and the drying racks, as well as the reduction in the mass of the dried material, the moisture content, and the humidity. The results showed that the heat wasted from the AC condenser is very potential to be used to dry herbal ingredients, because drying runs in relatively low temperatures. The heat output from the condenser can reach 42.4oC and 31% of air humidity. For turmeric, drying can last for 6 hours until the material reaches a 5-6% of moisture content in accordance with the SNI standards Keywords: drying, heat, herbs, condenser, air conditioner
