Abstract

ABSTRAKKulit coklat merupakan sumber lignoselulosa dari limbah pertanian dengan kandungan lignin mencapai 14.7 ± 0.35% (w/w). Lignin merupakan senyawa aromatik kompleks heteropolymer yang tidak mudah dipecah secara hidrolitik, sehingga jamur pelapuk seringkali digunakan untuk mempermudah proses degradasi lignin. Pada penelitian ini digunakan jamur pelapuk putih (S. commune). Selama proses pemecahan lignin, S. commune memanfaatkan enzim peroksidase dan lakase. Akan tetapi, produksi enzim lignolitik pada jamur pelapuk putih dalam jumlah kecil, sehingga diperlukan penambahan inducer untuk meningkatkan aktivitas enzim lignolitik. Tujuan penelitian ini adalah untuk mengetahui pengaruh penambahan CuSO4 terhadap aktivitas enzim MnP dan Lakase pada S. commune yang berperan dalam proses pemecahan lignin sehingga dapat dihasilkan berbagai macam senyawa kimia bernilai tinggi. Tembaga dengan konsentrasi 0 mM; 0.5 mM; 1.5 mM; dan 2.5 mM ditambahkan pada S. commune dan di inkubasi selama 5 minggu. Hasil kemudian diekstrak dan diuji aktivitas enzim MnP dan Lakase menggunakan spektofotometri. Hasil menunjukkan aktivitas enzim lignolitik S. commune terbesar yaitu 0.48 IU.L-1 untuk enzim MnP pada minggu ke-4 dengan penambahan konsentrasi CuSO4 1.5 mM dan 0.18 IU.L-1 untuk enzime lakase pada minggu ke-3 dengan penambahan konsentrasi CuSO4 0.5 mM dan 1.5 mM ABSTRACTAgricultural waste such as cacao pod is a source of lignocellulosic with 14.7 ± 0.35% (w/w) lignin compound. Lignin is a heterogeneous aromatic complex which are difficult degradated by hydrolitic, so rot fungi needed on lignin degradation process. This researches used white rot fungi (S. commune). S. commune are known to breakdown lignin with peroxidase and laccase enzyme. However, ligninolytic enzyme are produced only small quantities, so needed induction for enhancemend and activated ligninolytic enzyme. Purpose this research is knowing affected concentration copper on MnP and Laccase activty of S.commune during degaradation of lignocellulose, so can produce various of chemical added value compound. Various consentration copper are 0 mM; 0.5 mM; 1.5 mM; and 2.5 mM added in treatment and incubated for 5 weeks. Yield extracted and MnP and Lakase activty is measured by spectrophotometry. The maximum activities enzyme synthesized by S. commune were observed as 0.48 IU.L-1 for manganese peroxidase (MnP) after 4 weeks incubation at 1.5 mM CuSO4 and 0.18 IU.L-1 for laccase after 3 weeks incubation at 0.5 mM and 1.5 mM CuSO4

Abstract

Some plants in swamps are a problem because the growth rate is relatively fast, such as water chestnut (Eleocharis dulcis), kalakai (Stenochlaena palustris), and water hyacint (Eichornia crassipe)s. Therefore, various technologies are always traced to increase the use value of these swamp plants. One of the uses is by making organic fertilizer to support the availability of nutrients for plants. The purpose of this study is to utilize swamp plants and compare the pH, C-organic, N-total and C / N ratio values ??of each swamp plant. The study was conducted at the Soil Laboratory of the Faculty of Agriculture, University of Lambung Mangkurat in October - November 2014. The study used a single, completely randomized design (CRD). The factors studied were swamp plant organic material consisting of 3 treatments, namely: B1 (rat purun); B2 (kalakai); and B3 (water hyacinth). Each treatment was repeated 6 times, so that 18 experimental units were obtained. The results showed that water water hyacint had the highest N-total and the lowest C / N ratio compared to kalakai and water chestnut.

Abstract

As the world's largest palm oil producer, Indonesia has enormous potential for producing palm kernel expeller waste. Only 7% of Indonesia's palm kernel expeller (PKE) is processed into animal feed. It is necessary to utilize both wastes from palm oil processing and the workers' environment to support certification in palm oil plantations. This research aims to identify amino acid and lipid profile, total protein, fat, feeding rate, and survival rate BSFL using a palm kernel expeller for feed. The feed experiment in this research was PKE, fermented PKE, PKE with food waste, and fermented PKE with food waste as a control. The optimum result was fermented PKE with food waste with a protein total of 51.45%. Using BSFL for feed should have high protein content and low fat. The fat of BSFL fermented PKE with food waste is lower than BSFL with food waste. The feeding rate, survival rate, and BSFL mass are lower than BSFL with food waste. BSFL has the potential to reduce PKE waste and domestic food waste. The amino acid profile of BSFL PKE with household food waste consists of L-Glutamic Acid, L-Leucine, L-Arginine, L-Tyrosine, L-Valine, and L-Phenylalanine. L-Glutamic acid was the highest amino Acid in BSFL (36.396 g/kg). The type of amino Acid in BSFL is suitable for animal feed. The lipids in BSFL PKE with household food waste are lauric acid, oleic acid, unsaturated fat, monounsaturated fat, palmitic acid, myristic acid, and linoleic acid. The highest content of lipids is lauric acid (12.126%). The type of fat in BSFL can be used to produce biodiesel.

Abstract

BSF larvae were the agents capable of breaking down large amounts of organic waste. These larvae were known to reduce organic waste effectively and produced larval biomass. The substrate type was one of the factors that could affect the larvae's performance. This study aimed to determine the effect of the type of substrate or organic waste on the growth and waste reduction performance of larvae. Larvae were reared for ten days on several organic wastes, including food waste, solid decanter, coconut pulp, and sago pulp. The growth rate, bioconversion rate, waste reduction index, and feed conversion ratio were analyzed. The larvae with the best reduction performance were then analyzed for protein and fat on days 7 and 10. The results showed that BSF larvae in food waste showed more growth than in other wastes. BSF larvae in food waste showed a high waste reduction performance, while BSF larvae in solid decanter showed poor waste reduction performance. The BSF larval biomass in food waste contained high levels of protein and fat (38.94 % and 42.86 %, respectively).
