Authors: Kobarsih M , Pustika A B 
Published: February 2021

Abstract
Optimization and dissemination of the use of agricultural machinery to achieve food sovereignty in Yogyakarta are carried out through a direct assistance program through demonstration plots to farmer groups at three districts from 2017 to 2019. Planting and harvesting with machine were assessed in both technical and economic aspects. Regarding technical aspect, jarwo transplanter and combine harvester are suitable to be developed optimally in an irrigated rice fields that has a soil depth of less than 30 cm. Concerning economic aspect, jarwo transplanter saves labor and speeds up planting time, while combined harvester saves harvesting labor, post-harvest handling and accelerates harvesting process. Rice planting using jarwo transplanter requires 2 labors for planting rice in 7 hours covering a 1-hectare area. It is much more efficient than manual planting which requires 12 labors in 2 days for planting 1 hectares. Combine harvester reduced labor, as 2 people in 6 hours for harvesting 1 hectare of rice, compared to manual harvest which requires the 10 labors in 10 hours for 1 hectare. With labor and time efficiency, the agricultural machine was suggested to support synchronous cropping and harvesting of irrigated rice fields which in the end contributes to food sovereignty achievement.

Published: February 2021

Abstract
Drying is a process that is widely used in the food processing industry. There are several factors that influence during the drying process, one of which is the speed of air flow in the dryer unit. The air flow velocity inside drying unit can occur by forced airflow and natural airflow. Natural air flow is the flow of air created due to the difference in pressure caused by differences in temperature and air density, so there is no thrust by the blower. This study aims to estimate the natural airflow velocity in modeling system unit. This modeling system unit has a source of heat energy that can be used to adjust the room temperature level of the heat generator, and is equipped with a chimney that has an adjustable height and diameter. This research was conducted experimentally, through empirical mathematical model development using dimensional analysis. The variables measured include: heat generator room temperature (TS), system outside air temperature (TL), chimney diameter (d), chimney height (H), exhaust air flow velocity (V). The results of this study obtained mathematical model of airflow velocity. The mathematical model showed good agreement due to measurement results with average of errors was about 9%.

Published: February 2021

Abstract
Irrigated area has been decreasing since last decade in Indonesia. Surface irrigation scheduling performed predominantly due to water limitation and plant heterogeneity. Plant type and growth phase relate to the performance of water delivery. The research objective is to compare land use classification (LUC) from Landsat 8 and Unmanned Aerial Vehicle (UAV) with supervised algorithm. Supervised method (i.e. minimum distance algorithm) was applied. The result showed six LUC from UAV, i.e.: vegetative stage of dry crop (39%), ripening stage of dry crop (23%), vegetative stage of paddy (15%), tillage (15%), bare land (7%), and paddy nursery (6%). On the other hand, five LUC were performed by Landsat 8 image, i.e.: vegetative stage of dry crop (10%), ripening stage of dry crop (17%), vegetative stage of paddy (5%), tillage area (62%), bare land (6%). UAV’s image source performed more detail and accurate than satellite image. Thus, supervised method appropriate for UAV image for crop stage classification in small irrigation district.

Published: February 2021

Abstract
Majalengka is one of the corn-producing centers in West Java, but the average maize production is only 8.5 tons approximately, while the optimal corn production can reach 10-12.5 tons. This shows that the use of production inputs is still not optimal. This research was conducted using a structured questionnaire that given to 145 maize farmers to evaluate the knowledge, perceptions, and management practices of production inputs. Based on the research results, there were respondents who accept and reject the application of information on the application of production input. In addition, land area, number of seeds, use of urea fertilizer, and use of NPK had a significant effect on maize production in Majalengka. The results also showed that experience, input subsidies, and farmers’ knowledge had a positive and significant correlation with the use of inputs in maize farming. In addition, it is also seen that in the usage of inputs, farmers still referred to farming activities from generation to generation in their families and had not used standard maize farming needs yet. In addition, the use of production inputs was also strongly influenced by input prices and the availability of farmer capital.
