Published: November 2019

Abstract
Rainfall-runoff transformation is carried out when the series of discharge data is limited or unavailable. One of the components of rainfall-runoff transformation is unit hydrograph, which can be derived synthetically. The selection of the representative synthetic unit hydrograph is fundamental related to the results of the further calculation. This study compared three types of synthetic unit hydrograph, that were Gama I, Nakayasu and SCS. The study was conducted in Juana Watershed, which is located in Central Java Province and composed of 52 sub-watersheds. The calculation was carried out in the control point of Sentul Weir by using HEC-HMS version 4.2.1, in the case of January 2014 flood events. The results showed that the peak discharge from Gama I, Nakayasu, and SCS synthetic unit hydrograph were 80.78 m3/s, 85.32 m3/s, and 78.89 m3/s respectively. Those results then compared with the flood mark in Sentul Weir, which was estimated 76.53 m3/s. Therefore, the SCS method was determined as the representative synthetic unit hydrograph in Juana Watershed, refers to the minimum error value of 3.08%. Then the analysis of design flood hydrograph for the 52 sub-watersheds in Juana Watershed can be approached by using the SCS synthetic unit hydrograph method.

Abstract
In the last decades before entering 21fts century, many countries of the world have been facing critical issues of less in food production, lack energy availability and weak water recourses management as well. Beside of these issues another phenomenon dealing with climate change also is coming up and treating peoples in some respects. In the developing country such as Indonesia environmental load in term of increasing population rate occur tremendously. More peoples mean more resources have to be provided. However, some recourse is scares and others are not available every time. Better water resources management even this aspect was considered as critical one, but it was could be used as a tool to solve the problems properly. Increasing water users in the river basin would also create competition among of them. Recently about 80 % of water use in the world goes to irrigation purposes and most of them are managed inefficient and less effective way. Changing of government policy and change of ecology may made irrigation water management getting worst. Irrigation management could not implement by using conventional method. A new approach to make irrigation management running better must be setting up. The Ministry of public works and Housing to represent Government of Republic of Indonesia launched irrigation modernization of Indonesia program in year of 2011. This paper aims to present concept and implementation progress of the Program.

Published: November 2019

Abstract
The supply chain of shallot commodities in Bantul Regency involves several business actors including farmers, middlemen, collectors, wholesalers, retailers, and small traders. In the process of each supply chain, risks will always be encountered. The risks in each tier of shallot supply chain certainly need to be identified and analyzed. The categories of each of these risks will determine the appropriate supply chain risk management steps based on the risk categories obtained. This study was conducted to analyze the risk of shallot supply chains in the three largest shallot producing sub-districts. The Rapid Agricultural Supply Chain Risk Assessment (RapAgRisk) method is used to carry out risk analysis, and the sampling method used was purposive sampling and snowball sampling. The results show that the farmer is the tier with most risks faced compared to the others. Excessive stock is the risk that requires adequate priority to manage, and it is faced by all levels of the shallot supply chain. Meanwhile, farmers are the weakest supply chain actors in bargaining power, and the small traders are the most vulnerable actors in the face of risks associated with quality damage and slow sales rate.

Abstract
This paper studies important factors that influence the physical workload of rice harvesters. Rice harvesting in Java, Indonesia, mostly uses manual and semi-mechanical methods that require significant physical energy. These harvesting methods have potential Ergonomic Risk Factors (ERFs) that are skeletal, muscle, and peripheral nerve disorders called Musculoskeletal Disorders (MSDs). Surveys and observations of 7 workers of manual and 9 workers of semi-mechanical rice harvesting practices were done in Bantul Regency, Yogyakarta Province. The dependent variable of Cardio-vascular Load (CVL) was formulated in multiple linear regression equations by some independent variables, that were age, smoking habits, heart rate, and ambient temperature. The results showed that age and ambient temperature variables correlate strongly with CVL manual worker. CVL semi-mechanical worker was strongly correlated with age and heart rate. By F test, manual worker workload, 94.5% was significantly influenced by variables of age, smoking habits, heart rate and ambient temperature. CVL semi-mechanical workers were only 91.1%. To avoid high CVL, the age factor of workers is a major consideration. MSDs occur in the upper and lower back for manual workers, while semi-mechanical workers occur on the lower back and both hands. From the assessment of work posture in 4 elements of harvesting, transporting element was the activity with the worst posture. Ergonomic interventions are needed to reduce ergonomic risks in transportation.

Abstract
Many tropical agricultural products belong to climacteric group which need more attention to be able to extend or maintain their shelf life during storage. One of the most important phenomenon of climacteric produce is about the respiration rate of that produce. The following research was intended to investigate the rate of respiration of tropical climacteric products under various treatments including low temperature and the type of products. This research had developed respirometer device made from glass and thick plastic jar equipped with some needed sensing devices such as air temperature and humidity, product temperature sensing devices, and a tap for O2 and CO2 measurement. The respiration rate of banana, guava, and mango was succeded measured by using a closed system method. It was found that storage temperature, fruit type, and interaction between them were significantly affect the respiration rate. The changes in gas composition inside the respirometer were found to vary for each fruit studied. This could be referred to an internal composition for every fruit was different. The fastest rate of O2 consumption and CO2 evolution belong to banana and mango, respectively. The effect of temperature on respiration rate could be modeled using Arrhenius equation with a satisfactory results.

Published: November 2019

Abstract
Non-climacteric agricultural products are the commodity that cannot mature after being harvested so it is necessary to determine the right harvesting time to obtain the best quality. Generally, farmer will determinate the maturity of those commodity using a sound response from fruit tapping in addition to seeing the visual appearance. However, this is subjective so it is necessary to develop a more reliable and practical method. In this study a knocker maturity detection tool had been build and was used to evaluate three types of non-climacteric commodity, namely seedless watermelon aged 51, 54, 57, 60 DAP, eggplants aged 42, 44, 46, 48 DAP and cucumbers aged 27, 28, 29, 30 DAP. The knocking sound was recorded using Audacity 2.3.1 and then analyzed the frequency and magnitude parameters using Matlab R2014b. The results obtained were related to the physicochemical parameters of the samples. The results showed that the constructed knocker was able to distinguish the level of fruit maturity. In addition, it was also known that the right time for harvesting watermelon was 89 Hz or 50 dB, eggplant 157 Hz or 54 dB, and cucumber was 218 Hz or 52 dB.

Abstract
Popularity of cocoa-based drink has been growing since long time ago in tropical countries. Iced cocoa drink is highly consumed due to the fact that the ambient temperature in the tropical region is relatively high. This condition stimulates cocoa drink industries to continuously improve the quality of their products. This work investigated the performance of small-scale steam jet agglomerator used to produce instanised cocoa powder. This small-scale machine is designed to increase the solubility of cocoa powder, thus cocoa powder will be easily solubilised in cold water. In this study, a small-scale steam jet agglomerator was manufactured. Afterwards, the impact of three drying times, namely 60°C, 80°C, 100°C and three levels of agglomeration process cycle, namely 1,2,3 cycles as well as their interaction on the solubility and colour of the products was investigated. The results showed that the solubility increased as the number of agglomeration process cycle increased. With regard to the colour, the brightness level decreased as the drying temperature and number of agglomeration process cycle increased.
