Abstract

Subak system is one form of irrigation system that is able to accommodate the dynamics of the sociotechnical system of the local community. Irrigation water is managed with the principles of justice, openness, harmony and togetherness, through a flexible organization that is in accordance with the interests of the community. Irrigation systems are closely related to the distribution of irrigation water in subaks based on land area. One aspect that will be assessed in an irrigation system is the Irrigation Management Achievement Ratio (RPM). The purpose of this study is to determine the RPM classification in a subak by scoring in each RPM classification. Secondary data acquisition is done by survey method, direct observation and measurement. The collected data will then be analyzed using the Irrigation Management Achievement Ratio (RPM) method. Irrigation RPM for each subak is assessed using four ranges of values, namely Good if 0.75 1.60 The results of the analysis method of irrigation management achievement ratio in the distribution of water in the subak obtained by the upstream area RPM namely Pama Palian, Aya I and Aya II have a good RPM that is an average of 100%. The availability of water is so abundant due to the upstream subak, the first subak to take water in an irrigation area. And the most important thing is the optimal water supply management system. For the subak area the RPM is slightly different from the upstream area. The average RPM of the central irrigation area that has sufficient criteria is 15.5% while 84.5% is good. For the central irrigation area which has sufficient RPM criteria with a value of 15.5% caused by the distribution of water is not as optimal as the upstream irrigation area. For Subak downstream irrigation areas the overall average RPM is 100% good, this is because the distribution of downstream irrigation water distribution is optimal according to the area of the land.

Abstract

Cultivating land in agricultural activities requires optimal regulation of tractor requirements. The number of tractors that should be needed with the available land area is based on the availability of water in a subak with the aim of obtaining optimal tillage productivity, so a tractor with the availability of irrigation water is needed to irrigate the land to facilitate processing and streamline the land. The purpose of this study is to determine the number of tractors needed based on water availability by comparing the tractors available on subak. This study uses a quantitative analysis approach through a survey method by finding primary data, namely the measurement of discharge available for building and land measurements. The results showed that the tractors needed were based on the availability of water in the subaks of Tabanan Regency in theupstream, middle and downstream areas. For the nine subaks in the upstream area, the required rotary tractor with an average of 6 tractors can cultivate land reaching 87.3 ha or 1 tractor unit can work on an area of 14.6 ha with an average water consumption for 1 unit of tractor which is 27.16 lt/s. For the nine subaks in the central area of the tractor needed, with an average of 5 tractors, an area of 69 ha or 1 unit of tractor can work on an area of 13.8 ha with an average water consumption for 1 tractor unit, 26.84 lt/s. While the nine subaks in the downstream area of the tractor needed with an average of 10 tractors can cultivate land with an area of 114.5 ha or 1 unit of tractor can work on land with an area of 11.8 ha with an average water consumption for 1 tractor unit that is 12.1 lt/s.

Abstract

The high potential of damaged tomatoes during postharvest is one of the mostly faced problem in satisfying customer expectation. Postharvest handling is the final step that required to maintain good quality of tomatoes. The purpose of this study to identify customers need and satisfaction, analyze the cause of tomatoes quality deterioration and analyze the right strategies to control quality of tomatoes. The customers need and satisfaction converted using IPA (Importance Performance Analysis) method. The quality attributes as follow: fresh, clean, color, sweet and acid taste, moisture content, and no extraneous taste. The quality deterioration of tomatoes caused some of factors such as : (1) raw material:harvest method, postharvest handling, sorting method, packaging; (2) management system : food safety management application; (3) human resources : training and skills; (4) environment : natural disaster, climate and weather change; (5) equipment and method application : transportation and storage method. The formulation and strategies determination using Strengths Weakness Opportunities and Threats (SWOT) and Opportunities Quantitative Strategies Planning Matrix (QSPM) approaches. The final internal factor matrix is 3,193 which means on strong position and the final external factor matrix is 3,125 which means the opportunities are not fully optimized yet and the threats are not solved. The highest priorities that can be chosen as the alternative strategy are increasing investment assets while controlling cultivation development and optimized postharvest practices to produce the best quality oftomatoes using renewable technology up to 6,019.

Abstract

This research was conducted to determine the effect of nyisip in raw of legowo planting system toward microclimate and paddy’s productivity of Cigeulis variety. This research using completely randomized design, with six treatments and 3 replications, they are: K0 (the treatment which appropriated to farmers custom), K1 (the treatment of legowo 2:1 nyisip), K2 (the treatment of legowo 3:1 nyisip), K3 (the treatment of legowo 4:1 nyisip), K4 (the treatment of legowo 5:1 nyisip) and K5 (the treatment of legowo 6:1 nyisip). The result of this research shown that the treatment of K1 got the higest intensity of sun shine at 23.817 lux and got the highest temperature at 27,20°C. The treatment of K0 has the highest relativite humudity at 79,30%. The treatment of K5 is the highest productivity per area at 6,06 ton/ha.

Abstract

The objective of this study were to determine of wilting point pattern and field capacity in cultivation of sweet pepper (Capsicum annuum L.) in diffferents planting medium. The methodology that used in this study was quantitative method. Three different planting medium were set namely : P1 : rice husk charcoal media , P2: soil and compost mixed media with 2 : 1 ratio and P3: soil media. The water content of field capacity, temporary wilting point and available water for all treatments were observed start in week 2 to week 14 field capacity on rice husk charcoal, soil and compost mixed and soil media that row from 79.11% to 82,06%, 44.10% to 46.31%, and 36.20% to 37.41%. While the soil mousture of temporary wilting point of rice husk charcoal, soil and compost mixed and soil media is descreased from 42,99% to 25,84%, 13,95% to 8,95% and 14,39% to 10,23%. Available water of sweet paper plants on rice husk charcoal, soil and compost mixed and soil that is row increased from 5,20 cm to 9,65 cm, 5,72 cm to 6,33 cm and 3,43 cm to 4,86 cm.
