Abstract

Farming development in the agricultural sector in Kolaka District has challenges in markets, supply, and production. This study aimed to analyze seasonal cropland phenomena' scaling and distribution principles, focusing on vegetable and fruit crops. This type of research is descriptive and quantitative. The research location is in Kolaka District, Southeast Sulawesi Province, Indonesia. The data collection technique used data from Kolaka District in Figures 2020 and the Kolaka Regional Medium-Term Development document. The data analysis technique uses a scaling method presented in the form of an interval table. Then the data is viewed from the point of view of the principle of economic geography distribution. The results of this study, firstly, the potential harvest area spread in each sub-district is chili with ??158 hectares, then long beans, spinach, and kale. Second, seasonal fruit and vegetable production distribution in each sub-district is 2,048 quintals of chili, followed by eggplant, kale, long beans, and spinach. Meanwhile, data on scaling in harvested areas is very lacking, production potential is very less, and production levels are less. The recommendations for the potential development location of fruit and vegetable agriculture is Iwoimendaa Sub-district.

Abstract

Indonesian lettuce production is still lower than consumption.Lettuce production in Indonesia is still low because hydroponiccultivation needs more concern with the water and sunlight factors.This first study aimed to determine the contribution of water andsunlight to the growth of lettuce. The second study aimed to find outthe difference in lettuce production between the difference in waterand sunlight conditions. This research used the experimentalmethod. The research was conducted in a field laboratory andhydroponic village at the Faculty of Agriculture, Halu OleoUniversity. Data collection methods using field observations andmeasurements. The first objective data analysis techniquesdescribed water quality and sunlight measurements. The secondobjective data analysis used a description of the result of the lettucevariable costing. The results showed that water and sunlightcontributed to the production of lettuce. The water adds nutrients,and the sunlight does not direct to lettuce-affected plants, whichtend to have broad and healthy leaves. The good water and sunlightconditions contribute to pressing the cost of maintaining plants andraising the profit from lettuce production. These results areimportant to the attention of the water and sunlight conditions thatcan raise lettuce production in Indonesia

Abstract

The series of volcanic activities of Mount Raung triggered primary and secondary hazards in the area around the volcano. Kalibaru watershed is one of the areas prone to landslides due to secondary hazards of eruption activity in the direction of west and northwest part of this region. This study aims to optimize tourism by mapping landslide hazard using Spatial Multi-Criteria Evaluation (SMCE) around Mount Raung. This research used 46 points of landslide data through remote sensing, field observation. Ten landslide triggering factors, namely TPI (Topographic Position Index), TWI (Topographic Wetness Index), SPI (Stream Power Index), slope, distance to river, rainfall, geology, land use, distance to road, and soil type was used to map the landslide hazard. This study used ROC (Receiver Operating Characteristic) analysis to validate the landslide susceptibility mapping with an AUC (Area Under Curve) value of 0.93, which indicates that the mapping has a high accuracy value. The results showed that the landslide susceptibility is divided into three classes: high susceptible, moderate susceptible, and low susceptible. The high susceptible area covers 151.62 km2 (21%), the moderate susceptible area covers 407.99 km2 (56%), and the low susceptible area covers 166.79 km2 (23%). Based on the results of the mapping, tourism development in the area of Mount Raung is recommended in areas that are classified as medium and low landslide susceptibility.Keywords: Mount Raung, Landslides, SMCE, Tourism Development
