Abstract

Temperature and humidity control in rice nurseries is carried out to maintain the quality of rice seeds and avoid planting failure. Control is carried out using a prototype automatic device equipped with a water pump for watering and a mist maker plus a fan for humidifying. Based on observations, the prototype tool operates according to the given program. The water pump will turn on when the time shows 07:00 a.m. and 02:00 p.m. Meanwhile, the mist maker plus fan will turn on according to the regulated temperature and humidity conditions and can be applied to several regions in Indonesia. However, at the research site it will turn on when the temperature is > 27 °C and the humidity is < 70% and will turn off when the temperature reaches 27 °C and the humidity is 86%. The optimal air temperature for rice growth ranges from 19–27 °C with humidity in the RH range of 70–86%. Observations were carried out in two treatments, namely conditions with control and conditions without control. The results of seedling with control are better than without control. This can be seen from the growth of rice seedlings with control having a higher value than rice seedlings without control.

Abstract

Drying is an essential stage in post-harvest rice handling to reduce the moisture content to a safe storage level (≤14%). This study aimed to evaluate the field performance of a bed dryer automixing type rice dryer fueled by corncob biomass. The experiment was conducted at the Organic Rice Mill Tani Jaya II, Rowosari Village, Jember Regency, with three actual drying capacities of 1 ton, 1.2 ton, and 1.7 ton of paddy. The observed parameters included temperature distribution, moisture reduction, drying rate, and energy efficiency. The results showed that the highest temperature occurred in the lower layer of the paddy bed (35.5 ‐ 41 °C), while the final moisture content in all treatments was below 14%. The drying rate fluctuated due to the mixing process and variations in hot air temperature, with the highest efficiency obtained at a capacity of 1.7 ton (58.32%). These findings indicate that the bed dryer automixing type rice dryer performs effectively under field conditions with varying load capacities and is suitable to be applied as a biomass based drying solution that can accelerate the drying process and operate effectively during the rainy season.

Abstract

The Rainfall erosivity has a relatively high effect on soil erosion, in addition to being very difficult to predict and control. The Universal Soil Loss Equation (USLE) and The Revised Universal Soil Loss Equation (RUSLE) model are commonly used to predict erosion yield in Indonesia. However, these models have several erosivity formulations that give different results. In this sense, identifying the sensitivity of different erosivity formulations in both models above is important. The aim of this study is to analyze soil erosion yield prediction influenced by the difference in erosivity equation on the same rainfall data used in the models while other parameters used are the same. The monthly rainfall and annual rainfall data were tested using the erosivity formulas. The (1) Bols and (2) Utomo equations were tested using monthly rainfall data, while the (3) Bols and (4) Hurni equations were tested using annual rainfall data. The results show that the prediction of soil erosion yields estimates using monthly rainfall data in both models have no significant differences. On the other hand, soil erosion estimates using annual rainfall data in the models have significant differences, whereas the USLE model estimation results in 63% erosion yield on low classification (0-15 ton ha-1 year-1). Meanwhile, the RUSLE model estimates only 59% erosion yield on low classifications. Another result is that the USLE model estimates lower erosion yield than the RUSLE model when the models use annual rainfall data, which may give significantly different recommendations for soil conservation in Indonesia, especially in reducing erosion yield at the Watershed level.
