Abstract

Porang is a type of tuber that is widely cultivated because of its high economic value. Porang tubers have good prospects to be developed as main and functional food ingredients. Processed porang tubers include porang chips, imitation rice, porang noodles, jelly and other preparations. One of the important processing of porang is the process of making porang tuber chips. Porang tuber chips can be made using a chopper machine. This study aims to test the performance of the porang tuber chopper machine. The research includes the theoretical test of the chopper machine and the actual test of the porang tuber chopper machine. The efficiency and effectiveness of the chopper also determinted. With the existence of an effective and efficient chopper machine, it can help farmers to chop porang tubers into porang tuber chips. Porang tuber chips have a higher economic value than porang tubers; with the chopper machine is expected to increase the income of porang farmers. The actual working capacity of the machine is 115kg/hour, the theoretical working capacity of the machine is 226 kg/hour and 78% for the large part and 74% for the small part, the thickness of the slices produced ranges from 3-8 mm; reached 85%.

Abstract

The purpose of this research was to find out the influence of deficit irrigation at flowering phase toward yield and water productivity of soybean plants.  This research held on October 2018 to January 2019 in  Integrated Laboratory of Agricultural Faculty, Lampung University.  This research used Completely Randomized Design (RAL) with five treatments and four replications.  The treatments are 0-100% of available soil water content (ID1), 0-80% of available soil water content (ID2), 0-60% of available soil water content (ID3), 0-40% of available soil water content (ID4), 0-20% of available soil water content (ID5).  The result of the yield showed that deficit irrigation at flowering phase had significant effect to all growth variable, growt, and water productivity.  The highest production was achieved by the treatment of ID1 amount 24,3 gram.  Optimum water productivity was achieved by the treatment of ID2 amount 0,47 g/l.

Abstract

Tomatoes are coated with natural wax from the time they are planted on the tree, but the natural wax coating fades or even disappears due to post-harvest treatment. The coating application serves to replace the wax layer using tapioca with the addition of green grass jelly leaf extract. This study aims to determine the effect of the combination of green grass jelly leaf extract coating with 3 concentrations and 2 temperatures of storage conditions on 4 physical parameters of tomatoes, namely the level of hardness, weight loss, moisture content, and red color index of tomatoes and to determine the best treatment from the combination of treatments applied during storage. This study used a factorial Completely Randomized Design (CRD) with 2 factors. The first factor is storage temperature which consists of 2 temperature levels, namely room temperature (S1) and cold temperature (S2). The second factor is the concentration of green grass jelly leaf extract which consists of 3 levels of extract concentration, namely 10%, 30%, and 50%. If the results of the analysis of variance at the 5% level have a significant effect, a Duncan further test is carried out to see if there is an interaction between treatments. Based on the analysis, the treatment of variations in the concentration of green grass jelly leaf extract and storage temperature affected 3 physical parameters of tomatoes, namely the level of hardness, water content, and red color of tomatoes. However, it did not affect the weight loss parameters during 13 days of storage. S2K2 treatment was able to maintain the level of hardness, moisture content, and red color of tomatoes on day 13 with the standard of weight loss 10%. Based on further observations, the S2K2 treatment was able to maintain the shelf life of tomatoes up to 27 days of storage. Keywords: Coating, Concentration of Grass Jelly Leaf Extract Green, Storage Temperature, Tomato.

Abstract

Based on the survey result of vegetable crop production in Indonesia, the national carrot harvest area is 13,398 hectares spread over 16 provinces.  Meanwhile, the average carrot production in Lampung Province can reach 16,02 tons/year with a harvested area of 369 hectares (BPS, 2018).  Damage to horticultura commodities can occur if the post-harvest handling is not done well.  Many problems were found related to the decay of agricultural products due to the development of microorganisms which caused gread losses for farmers. Sterilization with UV lamps is an attempt to kill and eliminate pathogens or spoilage microbes that cause food spoilage. This sterilization aims to determine the effect of UV-C rays on the quality of carrot during storage. This research was conducted using a completely randomized design (CRD) with 2 factors, namely the irradiation distance factor (20 cm, 40 cm, and 60 cm) and the irradiation time (1-, 20, and 30 minutes). The data obtained were analyzed by ANOVA test. In the 60 cm irradiation distance treatment with an irradiation time of 30 minutes is the recommended storage distance because it can suppress root growth with an average value of 16,67 %, physical damage 14,58%, and gives the panelists the best assessment of the freshness level parameter with an average value of 3,24 (scale 5), texture with an average value of 3,25 (scale 5), and skin appearance with an average value of 3,15 (scale 5). Keywords: Carrots, Microbes, Influence, UV-C Rays, Radiation
