Abstract

The excess of water availability is caused by excessive water discharge during the rainy season, and it doesn’t distribute evenly between upstream and downstream, where upstream water availability tends to be oversupply and downstream is deficient. With such conditions, research is needed on excess irrigation water during the rainy season in order to perform an optimal water management in Ho Watershed. Research was conducted to determine the percentage of excess irrigation water available in each subak and determine irrigation water management techniques to be proportionate to each subak section. The acquisition of primary data is done by interview, observation, and measurement methods, while secondary data is obtained from (BMKG) Region III Denpasar. The data obtained was further analyzed with CROPWAT 8.0 to find the percentage of excess irrigation water that occurs during the rainy season and to determine the distribution portion of irrigation water. The results showed the percentage of excess irrigation water in the Ho watershed during the rainy season averaged 207,31%, middle 417,78%, downstream 239,05%. Water distribution management techniques in the upstream, middle, downstream during the rainy season so that the excess is proportional by changing the initial discharge in accordance with the approximation discharge.

Abstract

Before Subak farmers were familiar with tractors, land preparation was carried out using hoes or single-handed plows pulled by cattle. Land preparation with a tractor equipped with a complementary or rotary plow cannot be avoided in cases of overlap of processing results so that the processed soil results become inefficient. The overlapping results of the processing can be seen from the differences in the results of the processed soil. Based on these conditions, it is necessary to study the efficiency of tillage in Subak using single-axle tractors and rotary tractors in the first stage of tillage. Tractor work efficiency is measured based on a comparison between theoretical work and real work. Theoretical work is measured based on the width of the complement of the tiller, both short and rotary plows, and the average speed of the tractor's advance when cultivating the land. Real work is measured based on real work results in the field, namely the area ofland that has been successfully processed within a certain time span. Real work data was also confirmed based on the results of discussions with several tractor operators. From the results of the data analysis, it was obtained that the work efficiency of the short tractor was 77.3% and that of the rotary tractor was 55.2%.

Abstract

Land processing activities in Subak can reduce the develo pment of weeds, loosen the soil, and condition the biophysical properties of the soil. Subak in Bali is generally processed using hand tractors (either equipped with singkal plows or rotary plows). I f using a singkal plow, the stages of tillage include mak al (turning the soil), nyacahin (reducing the size of the chunks of soil), and then ngasahan (leveling). This research aims to determine the efficiency of land processing in the second stage of land processing in Subak using singkal tractors and rotary tra ctors. This research uses the observation method and measures the real (field) working capacity of the tractor used during land processing. Some of the assumptions used in this research are that the technical condition of the tractors used, the tractor acc essories used, and the operator's skills are assumed to be the same. The results showed that the performance efficiency of the rotary tractor in the nyacahin process (second stage of tillage) in Suba k was 41% and the performance efficiency of the singkal t ractor was 17.8%.

Abstract

Mangosteen is a tropical fruit with a high potential to be an export commodity, but the problem is that it quickly declines in quality due to its postharvest physiological process. The purpose of this study was to determine the effectiveness of ethanol vapor treatment and chitosan coating in slowing down quality deterioration and extending the shelf life of mangosteen fruit. Analysis used a factorial completely randomized design with two treatment factors. The first factor was giving ethanol vapor from the evaporation of ethanol solution with concentrations of 0%, 5%, and 10%; and the second factor was chitosan coating withconcentrations of 0%, 1.25%, and 1.5%. The parameters were weight loss, the intensity of damage, color difference, fruit hardness, total acid value, total dissolved solids, and organoleptic tests on the color of the flesh, the flesh taste, and the flesh aroma. Observations were for 25 days of storage at room temperature (28- 31ºC). The results showed that the single application of ethanol vapor had a significant effect on weight loss, while the single chitosan coating had a significant effect on the total acid and total dissolved solids. The ethanol vapor and chitosan coating interaction had a significant effect on weight loss, the intensity of damage, color difference, fruit hardness, and organoleptic the flesh color, flesh taste, and the aroma of the flesh. Treatment E2C1 was the best combination because able to maintain the quality and shelf life of mangosteen fruit up to 10 days. It had the lowest value of changes in the observed parameters such as weight loss, the intensity of damage, color difference, fruit hardness, and the highest organoleptic values for color, taste, and aroma of fruit flesh. The E2C1 treatment was able to maintain the visual appearance of the fruit until the 10th day based on fruit color, texture, and damage such as fruit rot.
