Abstract

Applications Remote Sensing and Geographic Information System for Mapping of Superior Commodities in Badung District. Superior commodity is one of the conditions in the development of agricultural areas included in (Regulation of the Minister of Agriculture No. 56 of 2016). As for the development of food crops agriculture is based on land suitability classes found in technical guidelines (Ministry of Agriculture, 2017). The two regulations require that each Province develop a master plan for developing agricultural commodities, which is based on superior commodities and land suitability classes. Quantitative and qualitative methods include: (1) identification and interpretation of land use using satellite imagery, (2) field surveys, (3) re-interpretation of satellite images, (4) Location Quotient (LQ) analysis for competitive superior commodities and Shift Share Analysis (SSA) for comparative advantage, (5) Mapping of superior commodities and land suitability of food crops. The use of paddy fields in Badung Regency is 9069.11 ha, moor (898,797 ha), and mixed gardens (3898,615 ha). Competitive superior commodities (LQ) for: (1) paddy rice, located in Abiansemal, Mengwi, North Kuta and Kuta Districts, (2) corn, peanuts, sweet potatoes and cassava in Petang District, (3) soybeans and green beans in Mengwi District. Comparative superior commodities (SSA) of paddy rice are found in the Districts of Petang and Mengwi. While sweet potatoes in Abiansemal District and cassava in Petang District. Potential agroecosystem suitability classes for food crops and secondary crops in the study area are generally classified as very suitable (S1) except in the Petang District which is quite suitable (S2-t, rc1) with a low temperature limiting factor and a rough texture. Increasing the suitability class of paddy and palawija requires fertilizing and adding organic materials to increase production.

Abstract

Sustainable agriculture aims to maintain high productivity while maintaining soil quality. The purpose of this study is to determine the sustainability performance of organic vegetable farming systems with soil quality indicators as a soil quality assessment tool. Soil physical, chemical, and biological properties in Chinese cabbage in Baturiti Subdistrict, Tabanan Regency, Bali, Indonesia, were evaluated as indicators for predicting organic cabbage production and yield. Soil samples were obtained from organic farming systems that have been going on for 1, 3, and 5 years after certification, compared with conventional farming systems. The results showed that the soil quality of the organic farming system after 5 years (OF5) was significantly higher than the conventional farming system. Physically, soil moisture at the field capacity in OF5 was significantly higher than that in the other systems. Chemically, the organic C and cation exchange capacity in organic systems were significantly higher than in conventional systems. The same results were shown by soil respiration, which means that there was high soil microbial activity. Based on the cumulative soil quality rating, it is concluded that the OF5 system met the sustainability criteria, with no high input required.

Abstract

Mapping of Climate Suitability and Variability for Corn Based on Geographic Information System (GIS). Each plant requires different growing conditions according to a certain climate. Climatic conditions can vary, such as El Nino and La Nina, which causes changes in the climate suitability of corn. Evaluation of climate suitability is important because climate factors are dynamic and difficult to control. This study aims to map the climate suitability of corn and map the climate suitability of corn when climate variability occurs in Bali Province. The analytical method used is matching and mapping using GIS. The results of this research showed that the climate suitability of normal period for corn in Bali Province is quite suitable (S2) and mostly (89.33%) is marginal (S3). Based on the limiting factors, it is divided into S2tc, S2wa, S2watc, S3wa and S3watc with the majority (498,568.26 ha) being S3wa. In general, climate variability causes changes in the area suitable for planting corn in Bali Province. El Nino had an impact on increasing the S2 area in the 2015 strong El Nino so that the S2watc area became 214,324.27 ha and the overall S2 area became 44.53%. The strong La Nina in 2010 reduced the overall S2 area to 0.49%, especially S2watc remaining only 2,756.75 ha.

Abstract

Mapping of Schmidt-Ferguson Climate Classification and Agroclimate Suitability of Red Chili Plant (Capsicum annuum) in Bali Province. Climate tends to be dynamic and changes continuously, as well as climate elements that continue to change in an area. Along with climate change and increasing rain gauge posts, the possibility of changes in climate types based on the Schmidt-Ferguson classification is inevitable. Thus, it is necessary to map the Schmidt-Ferguson climate classification in Bali Province based on data from 1991-2020 to provide an overview of the latest Schmidt-Ferguson climate classification in Bali Province. One of its uses is for the suitability criteria for agroclimatic zones for red chili (Capsicum annuum) plants. This study uses rainfall data from 1991-2020 from BMKG. This distribution data will be used to determine the Schmidt-Ferguson climate type. These results are related to the land suitability requirements for red chili (Capsicum annuum) land crops. GIS mapping will assist in zoning the Schmidt-Ferguson climate type classification area in Bali Province. The results of this study provide an overview of the latest Schmidt-Ferguson climate classification and agroclimatic suitability for red chili (Capsicum annuum) in Bali. There are significant changes when compared to the Schmidt-Ferguson climate classification for the previous period (1981-2010) with the same location and amount of data. Moreover, red chili (Capsicum annuum) plants are generally able to grow throughout the province of Bali, where the most suitable areas are in the northern coastal area.

Abstract

Corn is a strategic agricultural commodity in Central Java Province because this plant is the second main food crop commodity after rice. Evaluation of agro-climate suitability aims to assess suitable areas based on climatic conditions and efforts to overcome climate-limiting factors in order to achieve optimal productivity in corn cultivation. Satellite imagery can be used to overcome the lack of density of climate stations, which are the source of data for climate suitability evaluation. This study aims to validate GSMaP satellite rainfall data and Terra MODIS satellite air temperature data against BMKG observation data, create a distribution map of climatic conditions, and create a distribution map of agro-climate suitability classes based on GIS for maize in Central Java Province. This study uses rainfall and temperature data from 30 BMKG observation points and satellite imagery data for 20 years (2001–2020). The correlation values, RMSE, and MBE were calculated to validate satellite rainfall and air temperature data with observed rainfall and air temperature. Satellite data correction calculations are used to fill in the data at points without observation. The validation results show that the satellite data is valid and that there is a pattern of conformity with the observational data. Central Java province has an annual rainfall of 1,500 mm/year to 6,000 mm/year, an average annual temperature of 24.9oC to 28.1oC, and three to nine months of wet months. In some areas, the agro-climate suitability class for maize plants was in the moderately suitable category (S2wa, tc) with an area of 156,302 ha, marginally suitable (S3wa) with an area of 1,277,813 ha, and not suitable (Nwa) with an area of 2,008,673 ha.
