Abstract

Climate change is a change that occurs in the pattern of climate elements that are different from previous conditions. Climate change that occurs can lead to negative impacts on agriculture, namely the delay in starting planting time due to changeable weather not in accordance with forecasts until the problem of crop failure. East Lampung Regency is a regency that has the second largest agricultural land area in Lampung Province. Climate classification is the identification that is carried out to look for differences and determine the climate that occurs in a region. Climate identification can be done by monitoring changes in weather elements in a period of at least 10 years and at most 30 years. Oldeman's climate classification is to make climate types based on the number of wet months and dry months. The wet month category is the month that has rainfall >200mm and the dry month is with rainfall <100 mm. The purpose of this study was to determine the type of climate in East Lampung Regency based on oldeman climate classification, determine the right planting pattern for rice crops based on Oldeman climate classification, and determine the suitability of production and suitability of land for rice cultivation based on Oldeman climate classification. The method used in this study is the analysis of secondary data, namely rainfall for 10 years which is then interpolated with Geographic Information System applications. Based on the analysis results of East Lampung Regency has 6 types of climate, namely C1, C2, C3, D2, D3, and E3 with planting patterns applied in accordance with the oldeman climate classification. Suitability of land based on the type of climate obtained the results of 2 kinds of land types are very appropriate and marginal appropriate. While the suitability of rice production with climate classification East Lampung Regency has 13 districts that are appropriate and 4 districts are not appropriate. Sub-districts that are not suitable can be sought to have increased production results.

Abstract

Indonesia is one of the countries where the majority of the population are farmers, and rice is the main commodity. While rice drying is an important factor, the current climate and weather changes are an obstacle for farmers in the drying process. Rice with high moisture content is not safe for storage as it is susceptible to mold attack and deterioration. The purpose of this research was to study the effect of the level of inclination of the plastic position on the decrease in rice moisture content and the level of loss. The results of observations of the weather index for 4 days show that the intensity of the sun reaching the earth varies every hour. The parameters measured rice weights of 250 grams, 500 grams, and 750 grams showed that at a slope of 30 ° had the lowest moisture content and the highest rate of rice loss was in rice weights of 250 grams with a slope of 0 ° at 62% while the lowest rate of rice loss was in rice weights of 750 grams with a slope of 0 ° at 19%.   Keywords: Rice, Drying, Moisture Content Rice Weight, Slope.

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

Cherry tomatoes (Lycopersicum esculentum M.) are a type of tomato that many people like because they taste sweet and are rich in vitamins. However, conventionally cherry tomatoes have not been widely cultivated in Indonesia because besides of susceptible to disease, cultivation techniques in open fields are not well understood by many farmers either. This research aims to determine the appropriate size of the nutrient jar and hydroponic system. The experiment used a completely randomized design (CRD) which was arranged factorially with three replications. The first factor is the size of the nutrition jar which consists of 3 levels, namely 500 mL (P1), 1500 mL (P2), and 2500 mL (P3). The second factor was the type of hydroponic system consisting of Wick System (HW), Dry System (HD), and Floating System (HF). The results showed that the nutrient jar size had a positive effect on evapotranspiration, number of leaves, root length, number of flowers, fruit weight, and water content of the fruit.  The hydroponic system significantly affected the number of flowers, root length, fruit weight, and in general the Wick System (HW) had better performance compared to the Dry system (HD) and the Floating system (HF).  The interaction of the two treatment factors was not significant.  The data showed that the 1500mL Wick System (P2HW) was the most optimum treatment, based on the parameters of evapotranspiration/consumption of nutrient (2.6-3 liters), number of leaves 17 leaves), root length (23.4-25.1 cm), and fruit weight (14.1-15.22 grams) as well. Keyword : Cherry tomatoes (Lycopersicum esculentum M.), hydroponic, nutrient jar size. wick system

Abstract

Climate classification in Indonesia is needed to simplify climates, which vary greatly in number. The classification system that is often used in Indonesia is the Schmidt-Ferguson and Oldeman classification. The location of this research is Central Lampung Regency. In determining the climate type of Central Lampung Regency, there are 2 levels of the Schmidt-Ferguson climate suitability category for rice. The Sangat Sesuai (SS) category was 68,087.22 ha from 45.29% of the total ricefield area and for the Sesuai (S) category it was 82,235.04 ha from 54.71% of the total ricefield area. In Oldeman's climate suitability for rice, there are 2 levels of categories. The area for the Sangat Sesuai (SS) is 146,097.48 ha from 97.17% of the total ricefield area and for the Sesuai (S) category it is 4,252.54 ha from 2.83% of the total ricefield area. Rice suitability analysis was carried out to obtain a rice agro-climatic zone based on a ricefield use map and 5 regional limiting factors, namely: 1) Oldeman climate classification, 2) Schmidt-Ferguson climate classification, 3) Temperature, 4) Humidity, and 5) Slope. These 5 factors will be overlaid using Quantum GIS. The result of this analysis is that Central Lampung Regency is dominated by the Sesuai (S) category which is good for agricultural activities, especially rice plants. In the Central Lampung Regency, there are 3 categories of suitability for rice plants. In the Sangat Sesuai (SS) category of 63,780.33 ha of 42.43% of the total area of ricefields, for the Sesuai (S) category of 86,157.08 ha of 57,31% of the total area of ricefield, and in the Tidak Sesuai (TS) category of 389.00 ha of 0.26% of the total area of ricefield. Keywords: Climate, Oldeman, Rice, Schmidt-Ferguson, Scoring, Suitability

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
