Abstract

The decline in corn production is influenced by several factors, one of which is the suitability of land characteristics. This research analyses land characteristics' suitability and GDD for West Sumatra Province corn crops. The suitability of land characteristics is studied by combining the suitability of land characteristics with the GDD value in the area. The suitability of land characteristics is determined by matching plant growth requirements and land characteristics. The parameters used to determine the suitability of land characteristics are land use, slope, soil pH, soil texture and rainfall. GDD suitability by matching the accumulated daily temperature data during one growing season to the optimal GDD value for corn plant growth. This research created 12 planting time scenarios, and the analysis was carried out based on Regency/city administrative areas in the West Sumatra region. The analysis results obtained a suitable land area based on land characteristics and GDD values, namely an area of 1,206,079.48 ha with a planting season of December-March. Areas in West Sumatra Province with great potential for corn crop development are Lima Puluh Kota Regency, Pasaman Regency, Sijunjung Regency, South Solok Regency, and Tanah Datar Regency.

Abstract

Nutrient is one of the conditions controlled in a plant factory. Nutrient control must be based on the plant growth phase, but previous research has shown shortcomings in this area. This study aims to develop a nutrient control system in a plant factory based on the plant growth phase, specifically using Romaine lettuce. The research method used is the experimental method, with research stages including system design (controller modification, programming, and TDS sensor calibration testing) and system performance testing. The TDS sensor calibration test results showed an R² of 0.9999, indicating that the TDS sensor readings are very close to those of the TDS meter. The system performance test results showed that the developed system works well in controlling nutrient levels based on the growth phase of Romaine lettuce. The planting process lasted 30 days, from October 13, 2023, to November 11, 2023, with a total of 2,697 data points recorded by Antares. Nutrient requirements were adjusted per the growth phase of Romaine lettuce, with set points in the first to fourth weeks being 500 PPM, 600 PPM, 700 PPM, and 800 PPM, respectively. The average nutrient levels recorded in the first week were 518 PPM, 623 PPM in the second week, 721 PPM in the third week, and 820 PPM in the fourth week. The TDS sensor accuracy test results showed an R² of 0.9998, indicating that the TDS sensor performed well in controlling nutrient levels during the system testing, with an average TDS sensor reading error of only 1.17%. During the planting process, the total amount of nutrients added for each of nutrients A and B was 210.10 ml, with the total operating time of the control components being 314.34 seconds for each peristaltic pump of nutrients A and B.

Abstract

Each region has its own cropping pattern due to its particular characteristics. Crop production may be increased by adjusting the timing of planting. Remote sensing technologies can be used to monitor regions where planting occurs simultaneously. The purpose of this study is to assess the degree of uniformity at the beginning of the paddy cultivation season in West Sumatra. In each growing season, there are two early cultivation seasons in the West Sumatra province. 19% of the region started cultivation in the first period of the first cultivation season (CS1), and 81% in the second period. 4.2% of the region started cultivation in the first period of the second cultivation season (CS2), while 95.8% started planting in the second period. 35% of the region started planting in the first period of the third cultivation season (CS3), while 65% started planting in the second period. The level of uniformity at the beginning of the second cultivation season was higher than at the beginning of the first cultivation season

Abstract

One of the indicators of maintaining the quality of rice plants is monitoring and managing nitrogen requirements. Nitrogen (N) absorption in rice plants can be detected by remote sensing technology using Sentinel 2-A satellite imagery data using the NDRE (Normalized Difference Red Edge) method. This research aims to determine a mathematical model to predict nitrogen absorption in rice plants. This study uses the NDRE (Normalized Difference Red Edge) index value. The image used is Sentinel 2 imagery, namely channels 4 and 8 to see the Normalized Difference Vegetation Index (NDVI) value. Besides, the Normalized Difference Red-Edge Index (NDRE) is channels 5 and 8. The results of spatial and tabular data processing are analyzed per pixel and time trend to obtain patterns during one phase of the planting period. Based on the analysis of the NDVI and NDRE values of rice plants in Nagari Singkarak, the NDVI index pattern is in line with the NDRE index. At the beginning of planting (age ± 1 month) and the ripening period (age > ± 90 days) the NRDE value of rice plants is dominated by the low category NDRE value (red color). While when the rice is ± 60 days old, it is dominated by the high category NDRE value (green color). The estimation model for nitrogen uptake of rice plants in Nagari Singkarak based on NDRE data is y = 141.37 X + 0.0412, with a correlation coefficient (r) value of 0.97, which indicates a high correlation between NDRE values and nitrogen uptake.

Abstract

Nagari Lawang is located in Agam Regency, West Sumatra, which is a nagari situated in the highlands with a slightly steep to very steep slope with the most types of land use in moors/fields. This can directly encourage erosion. This study aims to analyze the optimal land use pattern for reducing the rate of erosion in Nagari Lawang. The method used to calculate the erosion rate is the Universal Soil Loss Equation (USLE) and to obtain the optimal land use in reducing the erosion rate is a simulation with three scenarios. The results of the study showed that 47.29% of the Nagari Lawang land area was at an erosion rate above the tolerance erosion with the category of light to very heavy. Based on land use simulations, planning scenario III by allocating the use of shrubland into mixed gardens with planting according to contour lines and the use of shrub land into mixed forests is the best scenario because it can reduce erosion by 39.05% of the total erosion of Nagari Lawang. The reduction of erosion on the diverted land (moors/fields and shrubs) reached 45.83% of the existing condition, which was 2105.928 tons/ha/year. The best scenario land use can be used as a reference by policy makers and the community in determining appropriate land management actions in Nagari Lawang. Keywords: Erosion, Simulation, Land Use, USLE.
