Alkyldiethanolamides (fatty acid diethanolamides) synthesis from Terminalia catappa L. kernel oil was optimized using lypozyme as a catalyst. The result showed that the optimal reaction conditions were 2 hours reaction time, with a ratio of oil mass (g) to diethanolamine (mmol) of 1:5, a ratio of oil mass to enzyme (g) of 1: 0.075, and a temperature of 40°C. The percentage of alkyldiethanolamides at optimum condition was 56-60%. The synthesis results were also analyzed by FTIR. FTIR spectra revealed specific absorption at several wave numbers (3434 cm, 1655 cm, 1280 cm), indicating that amide and alcohol bonds (C=O, C-N, and O-H) were formed. GC-MS was employed to identify the types of fatty acid diethanolamides that were successfully synthesized. The fatty acid diethanolamides formed were palmitoyldiethanolamide (R = 32.96 min) and oleyldiethanolamide (R = 35.57 min). The total nitrogen content of alkyldietanolamides was 0.26%, or 0.19 mmol of the amide group in 1 g of sample.

Omega-3 fatty acid is the essential fatty acid and important for human health. Omega-3 fatty acid is also really neededby pregnant and lactating mothers and also children to prevent the malnutrition. Omega-3 fatty acid is also reallyneeded by pregnant and lactating mothers, and children to prevent the malnutrition. The omega-3 fatty acid is commonlyfound in some fish like salmon, tuna, hering, and mackarel. However, those fish are expensive, so alternativesources relatively cheaper fish. One of fish that is low in price and high in production in Nusa Tenggara Barat is Sunglir(Elagatis bipinnulata ). The purpose of this research was to determine free fatty acids content, type of omega-3 fattyacids, and their compositions in head fish oil. Head of sunglir fish was used as a sample because the head was usuallynot consumed. Sunglir fish was obtained from the Ampenan beach (NTB) with a size of 20–30 cm. The extraction methodused in this study was soxhletation with n-hexane solvent and analyzed with Gas Chromatografi (GC), acid ethyl estersfrom the esterification enzymatic of fish oil. Result revealed that the fish oil contained 84% free fatty acid and 0.85%linolenic acid (ALA), 2.80% eicosatrienoic acid (ETA), 0.73% eicosapentaenoic acid (EPA) and 2.41% docosahexaenoicacid (DHA). Saponification and iodine number of head fish oil is 248.24 mg KOH/g oil and 227.16 g Iod/100 g oil.

This study aimed to separate fatty acid ethanolamides (FAE) through an enzymatic reaction of ethanolamine and the Terminalia catappa (Local name: Ketapang) seed oil by using reverse-phase high-performance liquid chromatography (RP-HPLC). A 4.6 mm × 150 mm, 5 μm SunFire C18 column was used. Separation optimization was performed by analyzing different variables, which includes mobile phase composition (acetonitrile/water), flow rate and sample concentration. The separation results showed that the retention time for all components was 4.5; 2.4; 12.9; and 6.3 min for fatty acid ethanolamides: oleoylethanolamide, linoleoylethanolamide, stearyl diethanolamide and palmitoylethanolamide, respectively. Inter-peak resolution of >1.5 indicated that each component was accurately separated.

Salah satu keterampilan yang berpotensi menggerakkan tenaga kerja ibu rumah tangga adalah pembuatan sabun padat. Sabun padat merupakan salah satu produk home industry yang dapat menjadi modal bagi ibu-ibu PKK untuk menumbuhkan kreatifitas mereka dan menumbuhkan jiwa wirausaha bagi mereka. Hal ini menjadi salah satu upaya yang telah dilaksanakan melalui Kegiatan Pengabdian Kepada Masyarakat yang bertema peningkatan keterampilan kelompok ibu-ibu pkk jempong melalui pelatihan pembuatan sabun padat dari minyak non pangan (non edible oil). Kegiatan ini berjalan dengan lancar serta menyenangkan bagi para ibu-ibu. Semua peserta dengan bersemangat ikut terlibat aktif dalam setiap tahapan kegiatan. Produksi sabun padat sudah banyak dipasaran, namun masih menggunakan bahan minyak pangan dan bahan baku sintetik yang tidak aman dan berbahaya. Pada kegiatan pengabdian ini telah dilakukan pelatihan pembuatan sabun berbasis minyak non pangan yang aman dan ramah lingkungan. Pelaksanaan Kegiatan Pengabdian Masyarakat ini bertujuan untuk memberikan pengetahuan dan keterampilan dalam pembuatan sabun padat kepada ibu-ibu PKK. Kegiatan ini dilaksanakan dalam beberapa tahap yaitu: pendataan peserta, penyampaian materi dan pendampingan praktek pembuatan sabun oleh Tim Pengabdian.
