Edible coating pati singkong (Manihot utilissima Pohl) terhadap mutu nenas terolah minimal selama penyimpanan
Get PDFPineapple is desirable to be consumed fresh, but it taking too long in stripping the pineapple's outer skin. Therefore, currently, the technology of processing horticultural products is minimally applied. Minimum fruit processing can speed up product shelf life. One way to overcome this is coating. Hydrocolloid edible coating is one type of coating with starch as the base material found in several types of tubers, one of which is cassava tuber. This study used a completely randomized design method consisting of one control sample and 3 treatments, cassava starch concentrations were repeated three times, namely A1: 3% cassava starch, A2: 4% cassava starch, A3: 5% cassava starch with 8 days observation. The variables observed were vitamin C, weight loss and color. The results showed that the highest vitamin C content was in the treatment of 5% cassava starch at 3.20 mg/100 g and the lowest was the control treatment of 3.15 mg/100 g. The smallest weight loss was A3 treatment of 73.75% and the biggest was control treatment 79.67%. The average value of the highest color was found in A3 treatment, which was around 66.92º showed yellow-red.Pineapple is desirable to be consumed fresh, but it taking too long in stripping the pineapple's outer skin.

Studi pemanfaatan pupuk abu boiler pada pertumbuhan bibit tanaman kakao (Theobroma cacao L.)
Get PDFBoiler ash is a solid waste from biomass combustion from palm oil mills. The boiler ash can be used as fertilizer because it has a high content in the samples of N, P, K and Mg and is safe for the environment. This study aims to determine the effect of boiler ash fertilizer on the growth of cocoa seedlings and get the optimal fertilizer dose when applied. This research was conducted in Jayapura – Papua for 3 months (September – November). This study used a completely randomized design that was repeated as many as 6 replications. The treatments given include: A0 (control), A1 (300 g.polybag–1), A2 (350 g.polybag–1), A3 (400 g.polybag–1) and A4 (450 g.polybag–1). Parameters measured were plant height, leaf number, leaf width, leaf length and plant wet weight. Based on statistical tests, the results showed that the use of boiler ash fertilizer on the growth of cocoa seedlings which was seen from all parameters had no significant effect. However, A4 treatment using 450 g of boiler ash fertilizer per polybag gives significant results for all parameters measured.Boiler ash is a solid waste from biomass combustion from palm oil mills.

The purpose of this study was to optimize the extraction, purification of albumin from snakehead fish to obtain higher levels of albumin. For that need to be investigated to obtain the isoelectric point of albumin extract with the greatest yield. Treatment research is the use of solvents is 0.9% NaCL and dilute HCL and extraction is by heating and without heating. The parameters tested were the determination of the isoelectric point, moisture content, albumin, and yield. The results obtained showed that the isoelectric point of albumin is at pH 4.6 with 62.9% albumin, 7.8% moisture content and yield of 11.6%.The high content of albumin in snakehead fish and proof of efficacy in clinical trials against several diseases, as well as the expensive commercial albumin preparations, making a snakehead fish alternative as a cheap source of albumin.

Effect of integrated plant nutrient management system in quality of mandarin orange (Citrus reticulata Blanco)
Get PDFNepal is a major producer among top twenty producing country of mandarin orange in the world. The productivity of the mandarin orange is very low as compared to other developed countries. Nutrient management is the serious problem in most of the orchard along the country. The experiment was conducted in Baglung district of Gandaki Province, Nepal in 2017 to study the effect of Integrated Plant Nutrient Management System (IPNMs) in quality parameters of mandarin orange. Seven group of treatment were assigned for experiment. All treatments were replicated three times in randomized complete block design. The fruits of T4 (Integrated nutrient) have greater fruit diameter: 5.26 cm, weight: 83.32 g total soluble solid: 14.53 brix % and lower titratable acidity: 0.846%. Fruits of T7 have more peel percentage (26.07%). These all findings indicate, integrated plant nutrient management system governs the quality of fresh mandarin orange.Nepal is a major producer among top twenty producing country of mandarin orange in the world.

Organogenesis tanaman kacang hijau (Vigna radiata L.) pada beberapa konsentrasi zat pengatur tumbuh sitokinin dan giberelin secara in vitro
Get PDFThis study aims to determine the organogenesis of mung bean plants (Vigna radiata L.) in several concentrations of cytokine and gibberellin growth regulators In Vitro. The method used was a Completely Randomized Design (CRD) with 6 treatments, 4 replications so that there were 24 experimental units. The concentration level used was P0 = no treatment, P1 = 2.5 ppm BAP + 2 ppm GA, P2 = 3.5 ppm BAP + 3 ppm GA, P3 = 4.5 ppm BAP + 4 ppm GA, P4 = 5.5 ppm BAP + 5 ppm GA, P5 = 6.5 ppm BAP + 6 ppm GA. The results showed that the growth regulator BAP and GA that given to each treatment had no significant effect on all parameters, this was due to the lack of elements of nitrogen to stimulate plant growth. The most effective treatment was found in P4 with a concentration 5.5 ppm BAP + 5 ppm GA which had the average value of germination age of 2 days after planting, then the average value of plantlets height was 10.07 cm, the average number of roots and number of leaves were as much as 2 strands, while the number of plantlet weight was 0.35.Penelitian ini bertujuan untuk mengetahui organogenesis tanaman kacang hijau (Vigna radiata L.) pada beberapa konsentrasi zat pengatur tumbuh sitokinin dan giberelin secara In Vitro. Metode yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan 6 perlakuan 4 ulangan sehingga terdapat 24 unit percobaan. Taraf konsentrasi yang digunakan P0= kontrol (tanpa perlakuan), perlakuan P1=2,5 ppm BAP+2 ppm GA, P2=3,5 ppm BAP+3 ppm GA, P3=4,5 ppm BAP+4 ppm GA, P4=5,5 ppm BAP+5 ppm GA, P5=6,5 ppm BAP+6 ppm GA, pengamatan dilakukan dengan mengamati umur berkecambah (HST), tinggi tanaman (cm), jumlah akar (helai), jumlah daun (helai), bobot planlet (g). Hasil penelitian menunjukan bahwa pemberian zat pengatur tumbuh BAP dan GA yang diberikan pada masing-masing perlakuan tidak berpengaruh nyata terhadap semua parameter, hal ini disebabkan karena kurangnya unsur nitrogen untuk memacu pertumbuhan tanaman. Perlakuan yang paling efektif terdapat pada P4 dengan konsentrasi 5,5 ppm BAP+5 ppm GA, dengan nilai rata-rata umur perkecambahan 2 hari setelah tanam, kemudian nilai rata-rata tinggi planlet yaitu 10,07 cm, rata-rata jumlah akar dan jumlah daun yaitu sebanyak 2 helai sedangkan jumlah bobot planlet yaitu 0,35
