Abstract

Brotowali stems (Tinaspora crispa. L) contains compounds that can be used as vegetable pesticides. The purpose of this study was to determine the phytochemical content present in brotowali stems, and effective concentrations of brotowali on mortality of O. rhinoceros larvae. This study used a Factorial Complete Ran domized Design with 6 treatments and 3 repeats, using concentrations of 0%, 10%, 10%, 20%, 30%, 40%, and 50%. The first factor is brotowali stem extract and the second factor is the method of application. The parameters observed were yield, phytochemical compounds, mortality, time of death 50% (LT50), and Lethal concentration (LC50). The results showed that brotowali stem extract contains phytochemical compounds, namely alkaloids, flavonoids, tannins, saponins, steroids, and terpenoids.  The yield produced from the rotary evaporator is 12.6%. Giving brotowali stem extract had a very real effect on the mortality of O. rhinoceros. BNJ further tests showed that 50% treatment had a very real effect with mortality of 66.67% in the feed application method, on the 11th day with a concentration of 50% and 40% feed method, then for an effective concentration to kill O. rhinoceros larvae, 50% was a concentration of 37.23% in the feed application method while in the spray application method, it could kill O. rhinoceros larvae 50% with a concentration of 63.86%.

Abstract

Uncaria gambir Roxb (URG) is one of the plants from West Kalimantan predicted to contain antioxidant and anti-breast cancer. This study aims to test the antioxidant and anti-breast cancer potential. UGR leaves were extracted by infusion method using water for 15 minutes with 4 repetitions at a temperature 70oC. A thick extract of 96.2351 grams (29.979%) was obtained from a sample weight of 321 grams of dried UGR leaves. In vitro antioxidant assay of the extract was investigated using 2,2-diphenylpicrylhydrazyl (DPPH) with positive control using quercetin and ascorbic acid, and the Ferric Reducing Antioxidant Power (FRAP) method. In silico screening showed that the biological agents in UGR had the potential as TP53 expression enhancer, antioxidant, anticarcinogenic, chemopreventive, and free radical scavenger. The antioxidant bioassay results showed IC50 values of 81.21 μg/mL, 73.39 μg/mL, and 9.17 μg/mL in DPPH for extract samples with positive control quercetin, sample extracts with positive control Vitamin C and Vitamin C with positive control quercetin, respectively. Meanwhile, the antioxidant activity of extract samples with the FRAP method showed value of 66,05 μg/mL. Anticancer bioassay result showed that UGR leaves extract with water solvent had the stron potentgial to inhibit 4T1 cells with IC50  87.72 μg/mL.

Abstract

The main ingredient of ice cream is cream. Regularly, ice cream is made from animal fat of milk, but can be made from vegetable fats as well. Coconut milk as a source of vegetable fat (cream) can be an alternative substance for making ice cream and is suitable for people with lactose intolerance. Making coconut ice cream requires a gelling agent dissolved in ice cream mixture (ICM). Corn starch that was modified physically (RS type 3) can be used in making of coconut ice cream which functions as a gelling agent. The research purpose was understanding of how to make coconut cream which can produce an overrun quality and organoleptic (hedonic) test. The study was conducted in a laboratory scale with a completely randomized design (CRD) with 4 variations in the proportion of the addition of this resistant starch and 3 replications which were tested for analysis of variant (ANOVA) and further tests with the Duncan and Kruskal Wallis multiple distance test. The results showed that the addition of resistant starch had an effect on the overrun significantly with the highest value of 23.53% at the 5% level of the proportion of ingredient. The hedonic test for the coconut ice creams at the proportion of ingredient was 5% as the highest score observed by the panelists whose the score was not significantly different from the proportions of the ingredients 3% and 6%.

Abstract

Abstrak Kegiatan PKM ini dilaksanakan di Desa Jeruju Besar Kecamatan Kakap Kabupaten Kubu Raya Kalimantan Barat. Pada daerah ini terdapat banyak tanaman kelapa yang berpotensi untuk dikembangkan sebagai usaha pengolahan kelapa tepung ampas kelapa dari limbah yang belum termanfaatkan dengan baik. Tujuan kegiatan PKM ini adalah memanfaatkan limbah ampas kelapa parut yang merupakan hasil samping pembuatan santan menjadi tepung kemudian diolah menjadi berbagai produk pangan sehingga dapat memberikan nilai tambah bagi peningkatan kesejahteraan petani kelapa & masyarakat di sekitarnya. Tekstur tepung ampas kelapa memiliki serat yang sangat tinggi. Tepung ampas kelapa yang dihasilkan dapat digunakan sebagai bahan substitusi untuk pembuatan berbagai macam makanan terutama untuk kue kering maupun basah. Metoda pendekatan yang digunakan dalam kegiatan PKM ini adalah metode informasi teknologi, metode transfer teknologi, dan evaluasi. Proses pemberdayaan masyarakat menggunakan metode informasi teknologi dengan cara tanya jawab, diskusi, dan penyuluhan, sedangkan metode transfer teknologi dengan cara pembimbingan, pelatihan, dan demplot. Evaluasi hasil kegiatan melalui kuisioner yang diberikan kepada peserta kemudian dilakukan analisis. Analisis yang digunakan secara deskriptif terhadap kegiatan yang telah dilaksanakan, kemudian analisis kuantitatif melalui kuisioner. Partisipasi dan kemampuan peserta dalam pengolahan tepung ampas kelapa parut dan membuat produk olahannya sangat tinggi. Seluruh peserta (100%) menyatakan mendapatkan pengetahuan yang bermanfaat tentang pengolahan dan pemanfaatan ampas kelapa parut ini, kemudian menyatakan minatnya yang besar untuk mengusahakan pengolahan ampas kelapa parut menjadi tepung dan berbagai produk pangan yang bergizi, sehat dan enak dari tepung tersebut. Kata kunci: kelapa parut, kue basah, kue kering, limbah padat, tepung ampas kelapa
