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. Keywords: fire vulnerability, forest fire, Tahura Nipa-Nipa, Kendari

ABSTRACT The current implementation of land suitability classification of Cocoa is based on the national standard of growing plant. Therefore the implementation of the land use at the specific location was not acceptable. It is important to evaluate the land suitability of the cocoa growing areas. This study was conducted at Kolaka Regency Southeast Sulawesi Province. This research was performed using a survey method based on the observation unit. Which is consist of 93 observation units. The climate, soil and environment observations were following the Soil and Agroclimate Research Centre ( PPTA, 1993); Department of Agriculture (DEPTAN, 1993 dan 2003) and the Indonesian Coffee and Cocoa Research Centre (PPKKI, 2008). The analysis of land suitability is base on the threshold factor using the mínimum. The results showed that the land suitability of the cocoa growing areas according to PPTA dan DEPTAN (1993) were classification full into 76.34% marginal suitable (S3), 12.90% currently not suitable (N1) and 10,75% was permanently not suitable (N2). On the other had based on the DEPTAN (2003) the cocoa growing areas were 83.87% S3 and 16.13% not suitable (N). While according to the PPKKI (2008) the S3 was 63.44% and the N was 36.56%.

This study aims to determine the land suitability class and efforts to manage the limiting factors that exist on land in Lasalimu District, Buton Regency. The method used is an independent survey by taking soil samples in each land unit (LU) for analysis in the laboratory. The results showed that the longan plant was quite suitable (S2) to be developed at LU 25 and 27 with a land area of 65.69 ha (0.95%), marginally suitable (S3) at LU 1-3, 5, 8-14, and LU 23 with a land area is 1,828.10 ha (26.50%), and is not suitable (N) at LU 4, 6, 7, 15- 22, 24, and LU 26 with a land area of 5,004.71 (72.55%). Potentially if efforts are made to manage the limiting factors for the development of longan plants, the suitability class becomes quite suitable (S2) at LU 3, 5, 8-14, 23, 25 and LU 27 with a land area of 1,207.54 (17.49%), marginally suitable (S3) on LU 1, 2, 4, 15, 17, 19- 22, 24 and LU 26 with a land area of 4,787.76 (69.29%) and not suitable (N) on LU 6, 7, 16, and LU 18. Management actions that need to be taken for limiting factors of nutrient availability are fertilization, nutrient retention by liming and adding organic matter, erosion hazard with conservation efforts such as planting according to contours, making terraces and planting cover crops, while for limiting factors such as air temperature, soil depth, slope, surface rocks and rock outcrops cannot be repaired because the limiting factor is permanent

Morphological characteristics of the soil contribute to the development of agricultural commodities. This study aims to identify the morphological characteristics of soil in cashew land use in Banga Village, Mawasangka District, Central Buton Regency. This research was conducted by survey method and field analysis on cashew land use. morphological observations were made on five soil profiles of cashew land use. The results of the study showed that the characteristics of soil morphology in the cashew center in Mawasangka District generally have a few percentage of rock outcrops and surface rocks (120 cm); reddish brown and dark brown soil color; clay and clay loam texture; medium and fine granular structure with a weak degree of development; soil consistency in dry conditions is soft, moist conditions are very loose, and wet conditions with slightly sticky adhesion and plasticity are plastic. Such soil characteristic conditions affect the stem circumference and height of cashew plants. Based on the results of the study, it is suggested that there needs to be a direction for cashew commodity management in the form of pruning, thinning, or replacing new plants accompanied by fertilization based on the morphological characteristics of the soil formed to obtain optimal productivity

People's cocoa plantations in Padangguni District are generally located in a steep slope topographic condition with this condition the potential for erosion is very high which can affect land productivity in the community cocoa plantation area. The purpose of this research is to predict the actual erosion rate, determine the erosion hazard index classes, and recommend soil conservation alternatives on different slopes in smallholder cocoa plantations in Padangguni Sub-District, Konawe District. This research was conducted from October to December 2022 in Padangguni Sub-District, Konawe District. The survey method was used in this research, and the prediction of erosion rates was conducted using the USLE method on 3 land units: land unit 1 located in smallholder cocoa plantations with a slope of 6% covering an area of 14.6 ha, land unit 2 with a slope of 24% covering an area of 17.2 ha, and land unit 3 with a slope of 22% covering an area of 60.5 ha. The research results showed that the highest actual erosion occurred in land unit 3 at 1,307.74 tons/ha/year, while the lowest erosion occurred in land unit 1 at 1.12 tons/ha/year. The tolerated erosion rates were 31.61 tons/ha/year for land unit 1, 25.70 tons/ha/year for land unit 2, and 26.95 tons/ha/year for land unit 3. The highest erosion hazard index was found in land unit 3 at 48.52 tons/ha/year with a very high criteria, while the lowest erosion hazard index was found in land unit 1 at 0.04 tons/ha/year with a low criteria. The recommended soil conservation techniques to ensure the sustainability of smallholder cocoa plantations include applying vegetative conservation techniques using plant residues as mulch and mechanical methods through the construction of traditional terraces or roraks. Both scenarios of soil conservation action methods can reduce the actual erosion rate, making them appropriate choices for reducing erosion rates on cocoa plantation lands

Nickel is an important main resource mineral in Southeast Sulawesi, which has deposited around 97.4 billion tons, and undoubtedly, nickel exports emerged in national and regional economic growth. Mining activities were carried out through topsoil and subsoil stripping, resulting in damage to the soil ecosystem and making it difficult for soil to recover. A study was performed to evaluate the changes in soil chemical properties and the growth of patchouli (Pogestemon cablin Benth) on nickel-mined soil treated with rice husk charcoal (RHC). A randomized block design was applied in this study, including six treatments of RHC with three replications. The treatments were without RHC (control), 1.5%, 3.0%, 4.5%, 6%, and 7.5% of soil weight. Data were analyzed descriptively for soil chemical properties; meanwhile, ANOVA was applied for plant growth. The results revealed that RHC increased soil pH, organic C, CEC, and available P, and conversely, the application of 4.5% of RHC decreased soil Ni and Fe content by 65.43% and 40.47%, respectively. The application of RHC up to 6% increased significantly the plant height and number of leaves as well as the dry weight of patchouli. The present study concluded that the use of carbon-rich soil conditioners such as rice husk charcoal is an imperative measure to restore the nickel-mined soil.

One of the priority watersheds in Southeast Sulawesi is the Poleang watershed. It is necessary to assess management performance to remain sustainable in its implementation. This research aims to determine the performance of poleang watershed management based on indicators of land conditions and determine recommendations for the direction of sustainable land management policies. The survey methods used in the research and analysis include land criticality, land cover and erosion in calculating carrying capacity. This research resulted in the fact that the land support in the Polean g watershed had a high class with a score of 1.25 based on the critical land sub-criteria. Sub-land cover criteria have an excellent category with a score of 0.5, and the erosion index sub-criterion has a very high category with a score of 1.5. Overall, the carrying capacity of the Poleang watershed is in the moderate category, so it is necessary to maintain land or increase the area of vegetation cover of the Poleang watershed through the application of vegetation conservation methods, technical conservation methods and mechanical conservation methods.
