Forest fires are one of the environmental problems that recur almost every year in Indonesia. This problem if not handled properly will certainly cause various negative impacts such as the emergence of haze that can interfere with public health and reduced forest cover, in forest areas. Taman Hutan Raya Nipa-Nipa (Tahura) as one of the Natural Preservation areas of Southeast Sulawesi Province is also inseparable from the problem of forest fires. The aims of the study were to analyze the level of forest fire vulnerability in the Tahura Nipa-Nipa area, especially in Watu-Watu Village, West Kendari Subdistrict, and the variables that most affect the level of forest fire vulnerability. Data analysis based on the weighting of each element is then carried out the determination of the vulnerability class using equations: forest fire vulnerability = {30 % x (land cover)} + {(20 % x height of place)} + {(20 % x Rainfall)} + {(10 % x distance from road)} + {(10 % x distance from river)} + {(10 % x distance from settlement)}. Mapping the class of forest fire vulnerability areas using geoprocessing with input data on land cover, place height, rainfall, and distance from roads, rivers, and settlements. Then an analysis is carried out and will be selected data according to the score of the level of forest fire vulnerability, namely very low/not a vulnerability with a score of 5, low with a score of 4, medium with a score of 3, high with a score of 2, very high /very vulnerability with a score of 1. The results showed that the level of forest fire vulnerability in Tahura Nipa-Nipa has 3 levels, namely the level of high forest fire vulnerability with an area of 68.51 ha, the level of moderate forest fire vulnerability with an area of 62.29 ha, and the level of low fire vulnerability with an area of 143.35 ha. The variables that most affect the level of forest fire vulnerability at the research site are land cover and community accessibility distance in the form of distance from the road and distance from the settlement.

The purpose of this research is to investigate the productivity of land by N,P,K fertilizer and time of planting peanuts in intercropping systems with maize. This research was conducted applying experimental garden at Agriculture Faculty of Halu Oleo University, Kendari. The research was conducted in the dry season, from August to November 2015. The research was arranged meant by split plot design with two replications. The main plot is NPK fertilizer dose (S) consisted of three levels namely 56-36-25 kg ha-1 (S1), 90-54-25 kg ha-1 (S2) , 124-72-50 kg ha-1 (S3). The subplots was planting time of peanuts with maize intercropping (W) consisted of three levels, namely planting time of peanuts 10 days before planting (DBP) maize (W1), planting peanuts with maize simultaneously (W0), and planting peanuts 10 days after planting (DAP) maize (W2). There are nine treatment combinations of two factors mentioned. Each combination treatment was repeated three times, coupled with each of the three experimental plots for monoculture cropping systems of peanuts and maize. The total number of units was 45 units experimental. Data experiments were analyzed by using analysis of variance followed by Duncan's Multiple Range Test. The results showed that the treatment time 10 DBP planting peanuts with maize to increase productivity, reduce competition index and efficient of the use fertilizer. Provision of fertilizer NPK 124-72-50 kg ha-1 dose can increase growth and yield of maize and peanuts

This research aims to determine the effect of subsurface irrigation water level and biochar application on the growth and yield of lowland rice. The research was conducted at Experimental Garden I, Faculty of Agriculture University Halu Oleo. The study consisted of two factors of treatments laid out in an RBCD-based factorial experimental design. The first factor consisted of four levels of subsurface irrigation (S) (i.e., 0, 4, 8, and 12 cm below the soil surface). The other factor also consisted of four levels of rice husk biochar (B) (i.e., 0, 10, 20, and 30 metric tons ha–1). Each treatment combination was given three replications. The collected data were analyzed with ANOVA and the differences among treatments were tested with DMRT at P=0.05. The study showed that both factors had no interaction effect on all parameters. The subsurface irrigation treatments, however, showed significant effects on plant height (56, 70, 84 DAS), leaf area (56, 70 DAS), flag leaf area, dry weight of root and shoot, panicle length, number of grains per panicle, grain weight after harvest per hill, dry weight of 1,000 rice grains, and yield. On the other hand, the biochar treatment only showed significant effects on leaf area at 70 DAS, flag leaf area, number of grains per panicle, grain weight after harvest per hill, and dry weight of 1,000 rice grains.
