Abstract

Effect of Harvest Time on the Save of Long Bean Seeds (Vigna sinensis L.). Supervised Long bean plants have indeterminate growth type, ie vegetative growth is still active even though it has entered the generative growth phase. The indeterminate growth type causes the pods to form cook not at the same time. When harvesting long bean pods for quality seed production, it needs to be studied. The seeds before planting must undergo a process of storing both short and long term storage, so the seeds saving power that produced from the time of harvesting different pods also needs to be studied. This study used a completely randomized design (CRD) with three treatments when harvesting pods for seeds, namely physiological pre-cooking, harvesting at physiological ripe, and harvest after physiological cooking. The treatment was repeated nine times. The results showed that the treatment of harvest time had an effect on the shelf life of the beans. Harvest time when physiologically cooked has the longest shelf life compared to harvest time after or before physiological cooking. Seed quality when harvested physiologically during storage obtained the highest compared with the quality of seed yields before and after physiological cooking.

Abstract

The Application of Geographic Information System (GIS) for Study of Groundwater Fluctuations and Characteristics of Aquifers at West Denpasar District Communities that have not been served by PDAM as much as 47.62%, use ground water to fulfill their clean water needs. The purpose of this study was to determine the distribution of dug wells, distribution of groundwater surface, fluctuations, flow direction and characteristics of aquifers in West Denpasar Subdistrict. This research was carried out by descriptive quantitative method. Analysis was carried out from survey data by using ArcGIS software. The results showed that the highest number of dug wells was found in Pemecutan Klod Village (31,25%). Groundwater surface depth in the dry season was 84.38% classified into 0-5 m class and in the rainy season 90.63% also classified as 0-5 m class too. Almost all of the southern West Denpasar Subdistrict has 0-5 m fluctuations. Groundwater in the West Denpasar Subdistrict is predicted to flow to the South, Southeast and Southwest. There are two types of aquifers in West Denpasar Subdistrict that is shallow aquifers and deep aquifers. Shallow aquifers are at 2-20 m depth with a maximum thickness of 18 m and are composed of passive and breccia material. Deep aquifers are found at 12-24 m depths with a minimum thickness of 12 m and are composed of passive and tufa material. It is estimated that both types of aquifers are good aquifers.
