Soap is one of the cleansers made by chemical reactions between sodium or potassium bases with fatty acids from vegetable oils or animal fats, such as coconut oil, VCO, palm oil, castor oil, olive oil, soybean oil, cocoa fat, tallow and lard. The purpose of this study was to determine the effect of comparison of coconut oil with cocoa fat and heating temperature to the characteristics of soap and determine comparison of coconut oil with cocoa fat and heating temperature to produce the best soap characteristics. This study used factorial randomized block design with two factor experiments. The first factor was the comparison of coconut oil with cocoa fat which consists of five experimental levels, namely: 0:60, 15:45, 30:30, 45:15, 60: 0. The second factor was the heating temperature which consists of 3 experimental levels, namely: 60?C, 70?C, 80?C. The results showed that the comparison of coconut oil with cocoa fat and heating temperature and the interaction between the two treatments had a very significant effect (P<0.01) on rendemens, texture, and soap foam. Comparison of coconut oil with cocoa fat and heating temperature had a very significant effect (P<0.01), but the interaction between the two treatments had no significant effect (P>0.05) on soap water content. Comparison of coconut oil with cocoa fat was very significant (P<0.01), but the heating temperature and interaction between the two treatments had no significant effect (P>0.05) on free fatty acids and soap-free alkalis. The best treatment was obtained from an alternative treatment comparison of coconut oil with cocoa fat 15:45 and heating temperature 70?C with soap rendemens of 88.36%, soap texture of 4.90 kg, soap foam content of 72.64%, soap water content  of 13.73%, free fatty acid levels of 0.40 (ml equivalent NaOH/g), soap free alkalis of 0.05%.

Carica Pubescens

Soap is a mixture of sodium compounds with fatty acids that are used as a body cleansing agent, in the form of solid, foam, with or without other additives and does not cause irritation to the skin. To improve quality, bath soap can be given additional ingredients that contain vitamins and various nutrients needed by the skin such as the addition of extracts of karika fruit (Carica pubescens). The purpose of this research is to find out the right formulation in making karika soap. This research used an experimental method with randomized block design (RCBD), consisting of two factorial variations in the concentration of karika juice (0%, 100%, 80%, 60%) and variations in the concentration of NaOH (30%, 35%, and 40% ) so that 12 treatments were obtained each with 3 replications. The process of making soap uses the hot process method. Soap quality analysis is carried out by comparing the results of chemical tests for karika soap with SNI 06-3532-1994 (SNI for solid bath soap), foam stability test, soap hardness, and organoleptic test. The data obtained were analyzed using ANOVA with a confidence interval of 5%. If an effect is found on one of the variebel, a further Tukey test is performed. The results showed that the water content, pH, and free alkali did not meet SNI, while the amount of fatty acids and mineral oil was in accordance with SNI, the significant difference between treatments was only in the water content. Karika soap has abundant and stable foam. The higher concentration of karika juice make the lower hardness of the soap. Organoleptic test results showed a low level of preference for panelists on karika soap products. The suggestion from this research is that karika juice can be tried to applied it in the liquid bath.

ABSTRAK      Penelitian ini bertujuan untuk menyelidiki pengaruh dari pemberian pakan yang mengandung mikroenkapsulasi minyak kanola pada konsumsi, kecernaan nutrien, dan performa pertumbuhan pada domba. Lima belas domba garut jantan dengan rataan bobot badan awal 20.17 ± 4.65 kg digunakan dalam rancangan acak kelompok (RAK) pada periode pemeliharaan selama 100 hari dengan 3 perlakuan dan 5 kelompok sebagai ulangan. Perlakuan yang digunakan adalah P0 (kontrol / hijauan: konsentrat = 60:40), P1 (P0 mengandung 4% minyak kanola), dan P2 (P0 mengandung 4% mikroenkapsulasi minyak kanola). Hasil yang diperoleh dalam penelitian ini menunjukkan bahwa tidak ada perbedaan untuk performa, konsumsi dan kecernaan nutrien. Suplementasi minyak kanola murni maupun terenkapsulasi sebagai sumber energi dalam ransum domba, menghasilkan pertambahan bobot badan harian (PBBH) dan efisiensi penggunaan pakan yang terbaik. Proporsi asam lemak tak jenuh pada perlakuan suplementasi mikroenkapsulasi minyak kanola 8% lebih tinggi dibandingkan dengan kontrol. Perlakuan minyak kanola murni meningkatkan (P<0.05) proporsi asam stearat (C18:0) dibandingkan perlakuan lainnya. Sehingga, dapat disimpulkan bahwa suplementasi 4% mikroenkapsulasi minyak kanola di dalam ransum, selaian menghasilkan PBBH dan efisiensi pakan terbaik juga mampu melindungi asam lemak tak jenuh (ALTJ) dari proses biohidrogenasi rumen tanpa mengganggu konsumsi dan kecernaan nutrient ransum.Kata kunci: konsumsi, kecernaan, mikroenkapsulasi, minyak kanola, performaABSTRACTThe aim of this study was to investigate the effects of feeding diets with microencapsulation of canola oil on intake, nutrient apparent digestibility, and growth performance of lambs. Fifteen male garut lambs with an initial average body weight of 20.17 ± 4.65 kg were used in a randomized block design (RBD) for a 100-days feeding period with 3 treatments and 5 groups as replication. The treatments were P0 (control/forage:concentrate = 60:40), P1 (P0 contained 4% of canola oil), and P2 (P0 contained 4% of microencapsulated canola oil). The results showed that there was no difference in the growth performance, intake, and digestibility of nutrients. The best of average daily gain (ADG) and feed efficiency results from the supplementation of pure canola oil or encapsulated canola oil in diets. The proportion of unsaturated fatty acids in the supplementation of microencapsulated canola oil treatment was 8% higher than control. The treatment of canola oil supplementation increased (P<0.05) the proportion of stearic acid (C18:0) compared to other treatments. Thus, it can be concluded that supplementation of 4% of microencapsulated canola oil, besides produced the best of ADG and feed efficiency, was also able to maintain unsaturated fatty acids from the rumen biohydrogenation process without detrimental effects on nutrient intake and digestibility in lambs.    Keywords: canola oil, digestibility, intake, microencapsulation, performance

ABSTRACT: The objective of this study was to explore the substitution of ractopamine by coconut or safflower oil in finishing pig diets. The study included 24 crossbred barrows weighing 78.00 ± 8.76 kg distributed in a randomized block design with four treatments and six replicates composed of: basal ration (BR), BR + 10 ppm ractopamine, BR + four 1 g capsules of safflower oil, and BR + four 1 g capsules of coconut oil. Performance evaluation showed that safflower oil, ractopamine, and coconut oil supplementation had a significant effect (P < 0.05) on weight gain and feed conversion. Carcass-related variables were also affected by the treatments (P < 0.05), with fat thickness 3 (FT3) reduced by the use of safflower oil, ractopamine, and coconut oil. Rib eye area was positively affected (P < 0.05) by diet, with ractopamine, coconut oil, and safflower oil supplementation treatments showing higher values than control diet treatment. The diets also affected fatty acid profiles (P < 0.05), with decreased myristic acid content in animals supplemented with ractopamine and safflower oil and increased deposition of palmitoleic and oleic acids in animals supplemented with coconut oil and safflower oil, respectively. Results suggested that both safflower oil and coconut oil can be used as substitutes for ractopamine.
