Penggunaan NaCL dan Asam Sitrat untuk Memperpanjang Umur Simpan dan Mutu Cabai Rawit (Capsicum frutescens L.)
No full textChili cannot be stored for a long time in a fresh condition because it was a living structure that is still carrying out metabolic reactions. Chili after harvesting still maintains the physiological system as it was still attached to the plant. Metabolic reactions will trigger chili damage quickly. The efforts to prevent this should be made to maintain the quality and shelf life of chilies by minimizing metabolic processes, such as suppressing the rate of respiration through regulating the environmental conditions of storage and use of preservatives. The study aimed to determine the effect of concentration of NaCl and citric acid on the shelf life and quality of chili. The study was arranged using a Completely Randomized Design (CRD) with a combination of types and concentrations of preservatives. with the treatment of NaCl concentrations of 1%, 2%, 3%, and Citric Acid respectively 1%, 2%, 3%. The parameters observed were weight loss, shelf life, texture, total microbes, and vitamin C content. The results showed that the use of preservatives significantly affected the shelf life and quality of cayenne pepper. The preservative NaCl 3% given a better effect on cayenne pepper, in terms of the lowest weight loss of 22.8%, the maximum shelf life of 78 days, the number of microbes 12 cfu/g sample, and the texture is rather soft after storage
Pengaruh Sistem Pertanaman Terhadap Pertumbuhan, Produktivitas, dan Viabilitas Benih Pasca Simpan Beberapa Genotipe Sorgum
No full textThe sorghum-cassava intercropping system is a solution to the limited land for planting sorghum in Lampung Province, which is a cassava production area. The aim of this study was to determine the effect of the cropping system on the growth, production, and vigor of the six months' shelf life of the seeds of five sorghum genotypes. The research was conducted on agricultural land in Karang Endah Village, Jati Agung Subdistrict, South Lampung Regency (5.28° SL 105.27° EL) at 82.3 masl and at the Laboratory of Seed and Plant Breeding, Faculty of Agriculture, University of Lampung. The experiment was arranged factorial in a split-plot and repeated as 2 blocks. The main plot was a cropping system consisting of a monoculture cropping system (p1) and an intercropping system (p2). Subplots consist of five sorghum genotypes consisting of Pahat (g1), GHP-1 (g2), GHP-3 (g3), GHP-5 (g4), GH-33 (g5). The sorghum that is planted intercropping with cassava is between 2 rows of cassava plants with 15 cm spacing in rows. On every two rows of cassava, a row of sorghum is planted. The spacing of cassava is 80 cm x 60 cm. The results showed that the intercropping system affected the number of leaves but showed better results at 71.20 g stover dry weight for GHP-1 and 50.10 SPAD for GH-33 for leaf greenness. The difference in cropping systems affected the productivity of sorghum seeds on seed weight per panicle, namely 31.83 g for GHP-3 which showed the largest yield compared to other genotypes but had no effect on the number of seeds per panicle. The treatment of five sorghum genotypes affected the germination rate by 36.83% / day for GH-33 and total normal germination by 84.50% for GH-33. Strong normal sprouts were 89% found in GH-33 from monoculture crops

No full textQuality control is needed by the company to improve the quality of the products produced so that they are by the company's standards and by consumer desires. Maintaining the quality of the products made is also necessary to reduce the company's quality assurance costs. The research objective was to analyze the quality control of the products produced and identify the factors that damage the products produced by the Ayu Tangkas Women Farmers Group (WFG). The method used in this research is the Statistical Process Control (SPC) method with analysis using the p-control chart and the Fishbone Diagram. The population in the study were all products produced by WFG Ayu Tangkas in December 2019. The results showed that the quality of snacks made by WFG Ayu Tangkas, as many as 4280 pieces, were under control. This can be seen from the 28 points between the Lower Control Limit (LCL) and Upper Control Limit (UCL). There are only two points that are above the UCL control limit. The factor that causes deterioration in Ayu Tangkas WFG snacks' quality is that the ingredients are not measured with certainty using only the snack maker considerations. Besides, they do not use manufacturing machines, so that the sizes are often not the same because there is no definite SOP for the manufacturing process. There is no promotion so that snacks are made still at a constant volume and the use of firewood in the manufacture so that the heat generated is unstable, causing the snacks to burn and break frequently
Kualitas Fisik dan Kandungan Protein Kasar Silase Kulit Buah Kakao Berbeda Klon Sebagai Pakan Ternak
No full textThis study aims to determine the physical quality and crude protein content of cocoa pod husk silage (CBC) from different clones. The pods used came from six clones, namely Sulawesi1 (S1), Sulawesi2 (S2), Local 01 (L01), local 02 (L02), local Padantana (LP), and a mixture of all clones (S1+S2+L01+L02+LP), which is referred to as mixed silage. The study used a completely randomized design (CRD) with silage treatment of cocoa pod husks for each clone with 30% rice bran added. Meanwhile, the bran was not added to mixed silage. The data were analyzed using the analysis of variance test (ANOVA), and the Duncan test followed the difference between treatments. The results showed that the silage of all clone treatments had good physical quality with a distinctive sour fermentation aroma and a color that did not differ much from the original color of each clone's cocoa pods. There are differences in crude protein content of mixed cocoa pod husk silage and between clones. The highest crude protein content was found in mixed silage, namely 6.02%, and the lowest in local clones 02, namely 4.80%
