Abstract

Irrigation water is very influential cultivative in subak. The condition of pollution in irrigation water needs to be measured in order to know the water quality for subak. This research determine to the quality of water irrigation for subak’s in Bali. This research was conducted on April 8th until May 8th 2019 at 9 subak in 3 (three) regency in Bali. The water sample was taken at Subak Air Sumbul, Subak Yeh Anakan and Subak Air Satang in Jembrana regency, Subak Guama, Subak Selan Bawak and Subak Jatiluwih in Tabanan regency, Subak Tegal Kauh Selat, Subak Tohpati and Subak Bugbug in Karangasem regency. This study used survey method and labolatory analyzed. The result of research showed that water irrigation quality obtained compared with the water quality standard based on Bali Governor Regulation Number 16 of 2016 concerning water standard quality. The water sample is done at two points on each subak, that is the inlet and outlet channels. Parameters of water quality is BOD, COD, EC (Electrical Conductivity), pH, Nitrite (NO2), Phosphate (PO4) and TDS (Total Dissolved Solids). The highest test result are shown by the parameters: BOD parameter the value is 8,078 mg/L at Subak Selat inlet channel, COD parameter showthe value is 21,735 mg/L at Subak Selat inlet channel. EC parameter show the value is 308 µmhos/cm at Subak Guama and Subak Selan Bawak inlet channel. pH parameter show the value is 8,40 at Subak Bugbug inlet channel. Nitrite parameter show the value is 2,606 mg/L at Subak Guama outlet channel. Phosphate parameter show the value is 0,214 mg/L at Subak Guama inlet channel. TDS parameter show the value is 238 mg/L in outlet and innet channel of Subak Guama. Overall the result still in accordance with group IV water quality standar for water irrigation.

Abstract

Occupational safety and health program was a system of program created for both worker and entrepreneur as an effort to prevent occupational accident and illnesses caused by working relationship within the working environment. The research aims to determine the influence of occupational safety and health on employee performance and to know how much the impact of occupational safety and health on employee performance. This method of research used questionnaires as a data collection tool distributed to .80employees at PT. Bali Maya Permai Food Canning Industry. The results of the multiple linear regression test showed the magnitude of the influence of occupational safety and occupational health variables on employee performance amounted to 68,43%. It showed that occupational safety and health had a positive effect on employee performance.

Abstract

Terraced agricultural field with an area of less than 0.1 ha per plot is difficult to reach by large size and large capacity agricultural machines. A carry type rice harvester is an agricultural machine that can be used on small and terraced field. The aim of this research is to design a cutting and guiding unit of paddy harvesting machine that easy to use on small and terraced paddy field. The parameters observed are effective field capacity (EFC), effectiveness of cuttingunit, effectiveness of guiding unit, fuel consumption and harvesting losses. The cutting and guiding unit is running well, which is shown by the percentage effectiveness of cutting unit is 99% and effectiveness of guiding unit is 100%. The performance test results show the EFC harvesting of this machine is 0.05 ha / hour, fuel consumption of 1.2 l / hour, harvesting is 2.1%. This carry harvester can be used in terraced rice fields that cannot be reached by other bigharvesting machines.

Abstract

The purpose of this study was to obtain the composition of the ingredients and coordinate the optimal activator on compost quality in accordance with the Indonesian National Standard (SNI) 19-7030-2004. The raw materials used in composting are bamboo shoots and cow dung waste. The activator used was from a 2-week fermentation process from a banana hump that was added to rice washing water and brown sugar. The composting process in this study used a bamboo basket with a height of 100cm and a diameter of 60cm. The method used is factorial Completely Randomized Design with two factors. The first factor is the composition of cow dung and tabah bamboo shoot waste which consists of 5 levels, namely: 100%: 0%, 75%: 25%, 50%: 50%, 25%: 75%, and 0%: 100%. The second factor is the concentration of activator consisting of 3 levels, namely 250 ml, 500 ml and 750 ml. Each time repeated 2 times. In the process of composting temperature and pH every day for 31 days. Water, C-Organic (%), Nitrogen (%) is observed at the beginning and end of the composting process. The combination of treatment of cow dung and bamboo shoots and the concentration of activators had a very significant effect on the compost and pH yield values. The best treatment composition is A3.B3 with a comparison of the composition of cow manure and bamboo shoot midrib (50%: 50%) concentration of 750 ml activator, producing compost with the best quality, namely with pH 6.93, moisture content 35.95%, C-organic 23.9%, N-total 1.46%, C / N ratio of 16.42%. The compost produced is blackish brown in color, has a crumb texture compared to other treatments.

Abstract

The purpose of this study was to determine the effect of degreening with various concentrations of ethephones on the quality of citrus fruits during storage. This study used a completely randomized design (CRD) with two treatment factors. The first factor was four levels of ethephon concentration is 400, 500, 600, and 700 ppm. The second factor was storage temperature consisted of 2 levels (28 ± 2 ℃ and 18 ± 2 ℃). Variant analysis showed that the interaction of various concentrations of ethephon in the degreening and temperature storage process affected significant is (p <0.05) on decreasing fruit weight, total soluble solids, colour different, vitamin C and total acid. The results showed that the combination of low temperature storage treatment with a concentration of 700 ppm ethephon was the best treatment to form orange color on orange peel and maintain the shelf life of citrus fruits.
