The Use of Rubber Seed Oil as an Alternative Plant Lipid Source for Stripped Catfish (Pangasianodon hypophthalmus) Diet

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.

Lipid Source

ABSTRACT Clarias gariepinus rearing is mostly done with intensive systems that use a lot of commercial feed. The price of raw material for the feed lipid source which is currently the main source of fatty acids in freshwater fish feed continues to increase and compete with human needs. Rubber seed oil (RSO) is considered feasible to be an alternative. This study aimed to evaluate the use of heated RSO as alternative lipid source in C gariepinus feed. The results of this study indicated that heating could reduce HCN levels in RSO by 95%. Even after heated RSO was inserted into the feed formulation there is still HCN in feed, however it did not affect the survival rate of C. gariepinus statistically. Heated RSO based feed shows a specific growth rate that was higher than non-heating RSO-based feed. Feeding with heated RSO also did not affect nutrient retention in C. gariepinus. This also followed by blood profile, blood chemistry and body fatty acids profile, MDA levels and SOD levels which were almost same as treatment feed using fish oil and corn oil. From these results, it can be concluded that heating can reduce 95% HCN content in RSO and can be used as a lipid source in C. gariepinus feed. Keywords: Aquaculture, essential fatty acids, growth performance, HCN, rubber seed oil. ABSTRAK Budidaya ikan lele Clarias gariepinus dengan sistem intensif menggunakan banyak pakan buatan. Harga bahan baku untuk sumber lemak pakan terus meningkat dan bersaing dengan kebutuhan manusia. Minyak biji karet (MBK) layak menjadi alternatif. Penelitian ini bertujuan mengevaluasi penggunaan MBK yang dipanaskan sebagai sumber lemak alternatif dalam pakan ikan lele. Hasil penelitian menunjukkan proses pemanasan dapat mengurangi kadar HCN pada MBK hingga 95%. Walaupun masih terdapat sejumlah kecil HCN pada pakan berbasis MBK yang dipanaskan, tetapi tidak memengaruhi tingkat kelangsungan hidup ikan lele (p>0,05). Pakan berbasis MBK proses pemanasan menunjukkan laju pertumbuhan spesifik yang lebih tinggi dari pakan berbasis MBK yang tidak dipanaskan. Pemberian pakan berbasis MBK proses pemanasan juga tidak memengaruhi retensi nutrisi ikan lele. Demikian pula parameter profil darah, kimia darah, profil asam lemak tubuh, kadar MDA dan kadar SOD hampir sama dengan pakan perlakuan berbasis minyak ikan dan minyak jagung. Sehingga dapat disimpulkan MBK proses pemanasan dapat mengurangi 95% kandungan HCN dan dapat digunakan sebagai sumber lemak dalam pakan ikan lele. Kata kunci: Akuakultur, asam lemak esensial, HCN, kinerja pertumbuhan, minyak biji karet.

Ignition Delay Period

In this study, different characteristics of sustainable renewable biodiesels (those have a high potential of their production worldwide and in India) were compared with the characteristics of neat diesel to determine optimistic biodiesel for the diesel engine at 250 bar spray pressure. Optimistic fuel gives a comparatively lower level of emissions and better performance than other selected fuels in the study. Rubber seed oil methyl ester was investigated as an optimistic fuel among the other selected fuels such as sunflower oil methyl ester, neem seed oil methyl ester, and neat diesel. To enhance the performance characteristics and to further decrease the level of emission characteristics of fuel ROME, further experiments were conducted at higher spray (injection) pressures of 500 bar, 625 bar, and 750 bar with varying ignition delay period via varying its spray timings such as 8°, 13°, 18°, 23°, 28°, and 33° before top dead center. Spray pressure 250 bar at 23° before top dead center was investigated as an optimistic operating condition where fuel rubber seed oil methyl ester gives negligible hydrocarbon emissions (0.019 g/kW h) while its nitrogen oxide (NOX) emissions were about 70% lesser than those observed with neat diesel, respectively.
