“…The high HCN is due to the fact that the HCN content of rubber seeds which are processed before being fermented still has a high HCN content of 35.45 (P0). Research results from Rahmawati [11] that rubber seeds soaked for 24 hours have an HCN content of 1,426 ppm. This is possible after steaming, no further soaking was carried out accompanied by periodic water changes.…”

Rubber seeds are plantation waste that can be used because they contain important nutrients for the body. However, rubber seeds also contain anti-nutritional substances in the form of cyanide acid (HCN). This study aims to evaluate the content of rubber seeds through the fermentation method with yeast based on the fungi Rhizopus oligosporus (tempeh yeast) and Neurospora sitophila (red oncom yeast) so that they are safe for consumption. The types of fungi came from the Feed technology Laboratory, Jember State Polytechnic. The dose of yeast was adjusted according to the treatment. The curing time is 48 hours at 30°C. This study used a completely randomized design (CRD) with 3x5 factorial pattern. The factor I was the type of microbes used. Factor II was the dose of yeast (0%;0.8%;1.6%;3.2%;6.4%). Each treatment was repeated 2 times. The different results were continued with Duncan’s multiple distance test to determine the differences between treatments. All of the fungi had the ability to degrade rubber seed HCN at yeast doses up to 6.4% (concentration 109 CFU/g). However, fermentation with Neurospora sitophila resulted in a higher protein content of rubber seeds, namely 20.64% when compared to using Rhizopus oligosporus, which was 19.93% (incubation time of 48 hours).

“…Biji karet dikupas atau dipisahkan dengan cangkangnya kemudian dilakukan proses penepungan menggunakan discmill. Selanjutnya biji karet dipress dengan menggunakan alat pengepress hidrolik dengan suhu 80 °C, kemudian dikukus pada suhu 90-105 °C selama 30 menit (Rahmawan & Mansyur, 2008). Tepung biji karet direndam dengan hexane dengan perbandingan 3:1 kemudian dikeringanginkan selama 24 jam.…”

“…Selain itu, biji karet memiliki nutrisi cukup baik yaitu kandungan protein sebesar 21,9%; karbohidrat sebesar 61,5%; lemak 15,8%, dan kadar abu 2,3% (Oyewusi et al, 2007). Biji karet mengandung zat antinutrien yaitu asam sianida (HCN), tetapi HCN ini dapat dihilangkan melalui pengukusan selama 30 menit (Rahmawan & Mansyur, 2008), serta melalui pemanasan (steam physical activity) (Sun & Jiang, 2010).…”

This experiment was conducted to improve the quality of rubber seed meal fermented using sheep rumen liquor based diet (RSMF) with amino acid supplementation for Nile tilapia Oreochromis niloticus. This experiment consisted of five treatments with three replications. The treatments were 0% protein from RSMF as control; 50% RSMF; 50% RSMF with lysine; 75% RSMF and 75% RSMF with lysine. Tilapia with an initial body weight of 6.29±0.12 g were reared for 40 days and the fish were fed three times daily at satiation level (8.00 am, 12.00 pm and 16.00 pm). The data were statistically analysed by using one-way analysis of variance (ANOVA) using software SPSS version 16.0 at 95% (p<0.05) confidence interval and Tukey test for the post hoc test. The results showed that the addition of lysine in the 75% RSMF diets could increased final weight, but did not significantly different to protein efficiency ratio (PER), decreased feed convertion ratio (FCR) and biochemical body composition. The data indicated that quality of 75% RSMF could improved after lysine supplementation, but still lower than using 50% RSMF and soybean meal as protein source. Keywords: amino acid supplementation, Oreochromis niloticus, rubber seed meal ABSTRAK Penelitian ini dilakukan untuk meningkatkan kualitas pakan dengan tepung bungkil biji karet yang difermentasi dengan cairan rumen domba (TBBKF) melalui suplementasi asam amino untuk ikan nila Oreochromis niloticus. Penelitian ini terdiri atas lima perlakuan dengan tiga ulangan. Perlakuan terdiri atas 0% protein dari TBBKF sebagai kontrol; 50% TBBKF; 50% TBBKF + Lisin; 75% TBBKF dan 75% TBBKF + lisin. Ikan nila dengan bobot awal 6,29±0,12 g dipelihara selama 40 hari dan pemberian pakan dilakukan tiga kali sehari hingga sekenyangnya (08.00, 12.00 dan 16.00 WIB). Data dianalisis menggunakan analisis sidik ragam (ANOVA) dengan menggunakan software SPSS 16.0 dan diuji lanjut menggunakan uji Tukey. Hasil penelitian menunjukkan bahwa penambahan lisin pada pakan 75% TBBKF meningkatkan bobot tubuh ikan akhir, tetapi tidak berpengaruh signifikan terhadap rasio efisiensi protein (PER), rasio konversi pakan (FCR) dan komposisi biokimia tubuh ikan nila. Hasil penelitian ini menunjukkan bahwa kualitas protein 75% TBBKF meningkat setelah suplementasi lisin, tetapi masih lebih rendah dibandingkan dengan penggunaan 50% TBBKF dan tepung kedelai sebagai sumber protein. Kata kunci: suplementasi asam amino, Oreochromis niloticus, tepung biji karet

“…These compounds dissolve in rubber seed oil, which has an impact on reducing fish growth performance (Komariyah et al, 2014;Shalihah et al, 2019). The physical treatment process through soaking and boiling rubber seed oil can reduce the content of cyanide acid (Setyawardani et al, 2013;Karima, 2015;Rahmawati et al, 2017). Furthermore, boiling rubber seeds at 100 o C for 30 minutes can reduce the cyanide acid content (Udo et al, 2018).…”

Dietary lipid in the forms of fish oil and corn oil are known as the best lipid sources. An effort to find an alternative to lipid sources other than both forms of oil can be done through the use of ts rubber seed oil. The study was conducted to evaluate rubber seed oil as a lipid source in the diet for increasing the growth of striped catfish (Pangasianodon hypophthalmus) fingerlings. A tested diet having isoprotein (30.14±0.01%) and isoenergy (271.26±0.08 DE kcal/100g) was used in this study. Fish oil, corn oil, and rubber seed oil at a total of 3% were used as the diet's lipid sources. Rubber seed oil was added to the diet at 0, 1, and 3%, respectively. After acclimatized to the experimental condition, striped catfish fingerlings (9.72±0.01 g) were randomly stocked in 12 aquariums (69x29x35 cm3; Volume 50 L) with a density of 15 fingerlings/container and fed on the tested diet at satiation for 40 days. The use of rubber seed oil as a source of lipid in the diet does not affect the survival rate and body fat (P> 0.05). The composition of 2% rubber seed oil in the feed gives the best growth in striped catfish fingerlings, with feed intake of 233.00±1.00 g, a specific growth rate of 2.01±0.05% day-1, feed efficiency of 75.45 ± 1.18%, protein efficiency ratio of 2.45 ± 0.11% and body protein of 44.03 ± 2.42%. There is a tendency that higher rubber seed oil content in the diet, produce better the fatty acid profile in the body of the striped catfish.
