Abstract

Determination of Harvest Time for Quality Seed Production of Long Bean Plants (Vigna sinensis L.). Seed maturity generally occurs at the same time as fruit maturity. When the fruit reaches its physiological level, it is the best time to get seeds with high quantity and best quality. Early harvest before physiological maturity many seeds have not been completely filled so that they will produce low quality seeds because many seeds are wrinkled. Meanwhile, when harvested after physiological maturity, the seeds experience weather conditions so that many seeds experience physical and physiological quality deterioration. The research aimed to get the right harvest time in the production of quality seeds of long bean plants. This study used a randomized block design with 6 treatments at harvest pods after blooming and 4 replications. The six treatments were harvest age 14, 17, 20, 23, 26, and 29 days after the flowers bloom. The results showed that the right time to harvest pods for the production of long bean seeds was 26 days after blooming, the color of the pods has changed from green to yellow, the seeds have the highest dry weight (7,56 g), the best germination capacity (100%), and maximum vigor (88,78%).

Abstract

Analysis Priority Factor of Water Catchment Area in Denpasar City Bali Province Denpasar City as the capital city and one of the tourism centers in Bali Province is experiencing an increasing need for residential land use, because Denpasar City has a fairly large population. This causes a reduction in the water catchment area, so that most of the water becomes runoff. Determination of water catchment areas in all areas using the same factors, namely, soil type, rainfall, slope, and land use. However, each factor will be influenced by environmental conditions which cause each factor to have a different priority value. Therefore, it is necessary to study the priority factors of water catchment areas in Denpasar City. This research was conducted from September to December 2021. The purpose of this study was to determine the determinants of water catchment areas in Denpasar City and the priority value of each factor. This study utilizes spatial technology, namely Geographic Information Systems (GIS) which uses the Spatial Multi Criteria Evaluation (SMCE) to determine the weight and priority value of the determinants of water catchment areas. This research produces an output in the form of a map of each of the determinants of water catchment areas. The results showed that the soil type factor became the first priority, the rainfall factor became the second priority, the land use factor became the third priority, and the slope factor became the last priority.

Abstract

Analysis Priority Factors of Flood Prone Areas in Denpasar City Bali Province Floods are caused by the low infiltration capacity of the soil and the overflow of surface water (runoff) due to the long duration of rain and the high intensity of rainfall so that it cannot accommodate the accumulation of rainwater. Denpasar City is one of the cities in Bali Province where floods often cause losses in terms of material and physical environment. The determinants of flood susceptibility use the same factors, namely rainfall, soil type, land use, slope, and elevation but are influenced by environmental conditions so that the priority value of each factor is different. Therefore, there is a need for a research of the priority factors of flood-prone areas in Denpasar City. The purpose of the research was to determine the determinants of flood vulnerability and priority factors for flood prone areas in Denpasar City using Spatial Multi Criteria Evaluation. This research was carried out in Denpasar City from August to December 2021. The method used was Spatial Multi Criteria Evaluation for weighting and determining priority values ??for determining flood susceptibility through Geographic Information System applications. This research produces an output in the form of a map of each of the determinants of flood vulnerability in Denpasar City. The results showed that the rainfall factor was the first priority, the land use factor was the second priority, the soil type factor was the third priority, the slope factor was the fourth priority, and the altitude factor was the last priority.
