Abstract

Pupuk pelet organik dari arang sekam padi,EM4 dan kotoran kambing,ayam serta jerami padi diSei Mencirim Medan Krio Kabupaten Deli Serdang, penggolahan pupuk pelet organik arang sekam padi 10 kg,kotoran kambing 25 Kg,kotoran ayam 25 kg serta jerami padi 40 kg,seluruh bahan dihaluskan menjadi tepung,selanjutnya ditambahkan EM4 diFermentasi selama 3 hari ,N dianalisa dengan metode Keldall dan P dengan menggunakan AAS sedangkan Dengan spektrofotometri Hasil pupuk pelet organik tanpa fermentasi diperoleh N : 1,18 %, P : 0,04 , % K:< 0, 003 mg/kg. Parameter pupuk organik fermentasi selama 3 hari N:2,39 %,P:0,03 %,K: <0,003 mg/kg. Selanjutnya jerami yang terbuang dapat dimanfaatkan sebagai pupuk pelet organik begitu pula kotoran kambing,ayam serta arang sekam padi,semua campuran dianggap limbah semua dapat bermanfaat.Parameter pupuk pelet organik yang diperoleh sesuai dengan SNI 19-7030-2004 setara dengan pupuk organik yang ada dipasaran.

Abstract

The utilization of carboxymethyl cellulose (CMC) from groundnut (Arachis hypogaea L) cellulose as stabilizer for cow milk yogurt has been done in three steps. The first step was α-cellulose isolation from groundnut skin powder which was analysed with FTIR. The result was compared to FTIR analysis of commercial cellulose to verify the compound obtained is cellulose. The second step involves alkalization process using isopropanol and NaOH, carboxymethylation process with sodium chloroacetate (NaMCA), neutralization using CH3COOH 90% and ethanol, purification with aquadest and followed by centrifugation and addition of acetone to produce carboxymethyl cellulose. The CMC produced gave positive result in the qualitative anlysis, the FTIR spectrum was similar to commercial CMC and the degree of substitution obtained was 0.71. The last step is yogurt making process. In this stage, the CMC concentration added was varied from 0 – 0.5%. Then, the yogurt produced went through quality analysis such as syneresis, pH, viscosity, protein, fat content and organoleptic tests. The best result was obtained at the addition of 0.5% CMC concentration with 7.69% and 2.11% protein and fat content, pH 4.6, viscosity was 1676.01 x 102 cP, low syneresis with 90.66% stability and 22 days of storage life. Organoleptic result shows that yogurt with 0.3% CMC addition gave the best result with distinctive aroma and sourness, and rather thick texture. The panelists preferred such yogurt to others. The quality analysis for yogurt with CMC stabilizer still meets SNI standard. [Use 10 pt Times New Roman for the abstract body with single spacing and 10 pt spacing for the next heading.

Abstract

Vitamin E consists of two parts, namely tocopherol and tocotrienol which are found as minor components in candlenut oil. The process of increasing vitamin E concentrate in candlenut oil aims to obtain higher vitamin E levels from candlenut oil through a major and minor component separation with adsorption and desorption methods with three types of calcium silicate hydrate adsorbent namely calcium silicate with 90% absolute ethanol (Ca-S 90), calcium silicate with 75% absolute ethanol (Ca-S 75) and calcium silicate synthesized from CaO (Ca-S). The three adsorbents were synthesized by hydrothermal method at 170ºC for 24 hours accompanied by stirring and characterized by XRD, SEM-EDX, and BET. Furthermore, the adsorbent was applied to enrich vitamin E concentrate in candlenut oil through the adsorption process using a glass column with a mass ratio between candlenut oil and adsorbent that was 1:1, then the vitamin E desorption process was carried out by adding n-hexane solvent. Vitamin E levels obtained after the adsorption and desorption process were for Ca-S 75 adsorbent was 764.41 ppm (1. 82 times enriched), for Ca-S 90 adsorbent was 1011.29 ppm (2. 40 times enriched) and for Ca-S adsorbent was 1029, 38 ppm (2.4 5 times enriched) from the initial vitamin E level in candle nut oil was 420.66 ppm. Ca-S adsorbent showed the best vitamin E enrichment.
