The changes of forest uses into agricultural land is a serious problem in Lawo watershed, South Sulawesi. Agricultural practices without implementing soil conservation and adequate agro-technology has caused high level of soil erosion and low land productivity. Management in Lawo watershed must be done with integrated soil and water conservation in order to increase agricultural production. This effort can be done with land capability evaluation. The purpose of this study is to evaluate the land capability of Lawo watershed using land capability category for data analysis. The results showed that Lawo watershed is dominated by land capability of class III with erosion (middle) as the dominant limiting factor which covers about 17,476.42 ha (49.68%). In addition, the class of land capability is followed by class IV with the slope (moderately steep) as the limiting factor and erodibility of soil (middle) covering about 10,059.8 ha (28.6%), land capability of class VI with slope (Steep) as the limiting factor with 7,638.32 ha (21.72%) coverage area. Land with class III can be recommended for dryland farming with adequate application of agro-technology, and water and soil conservation. While class IV and VI are not recommended for agricultural activities but for private forest or plantation forest.

Drought and water logging stress are the most critical environmental factors that affect tree seedling survival and growth in the field. In this study, 12 populations of white jabon (Neolamarckia cadamba (Roxb.) Bosser) were evaluated to determine the genetic variability among populations and correlation among morphophysiological seedling characters under drought and water logging stresses. Two research units were carried out by the randomized complete design with 2 x 12 factorial arrangements, i.e. (1) drought stress (2 treatments) and population (12 populations), and (2) water logging stress (2 treatments) and population (12 populations). Results showed that the responses of seedling traits were varied among populations under drought and waterlogging stresses. White Jabon seedling has higher adaptation to water logging stress than to drought stress. Kampar and Gowa populations have better adaptation to water logging stress. In drought stress, Gowa population had better adaptation followed by Nusa Kambangan population. Seedling height, total biomass and proline content characters based on value of broad sense heritability and correlation among characters, could be considered as important indicators for improvement programs for drought tolerance, while in the water logging stress, height, total biomass, root length and leaf area could be considered as important indicators for improvement program of white Jabon for tolerance on waterlogged sites.

Flora biodiversity is a strategic resource due its various potential uses for human benefit. Population growth is sometimes considered to be a contributory factor in the degradation of the biological resources, conversely, the population plays an important role in its conservation. This research aimed to understand the flora biodiversity management, structure and composition of plants in home-garden system. The research was conducted in Central Sumba Regency. Methods used were interview and observation. Data were analysed descriptively and qualitatively. The result showed that the flora biodiversity management in home garden based on poly-culture approach, a holistic beneficially as a socio-cultural-religious attribute, economic-income and ecology-conservation. The structure and composition of plant in the home-garden they include the variation of the important value index. The expansion of the residential areas positively impact the flora biodiversity conservation in home-garden system.

The characteristics of limestone post-mining soil are low physical, chemical and biological soil fertility, which have adverse effect on plant growth. Arbuscular mycorrhizal fungi (AMF) and compost application is expected to enhance plant growth. AMF association expand nutrients absorption area. Compost application provides nutrients and increases soil porosity, which significantly supports plant growth and AMF development. Therefore, the effectiveness of AMF or compost could be improved if both are applied simultaneously. The study was conducted to determine the effectiveness of the AMF and compost to teak seedling growth on limestone postmining soil. A completely randomized design was applied with factorial pattern. There are 2 factors of treatment i.e AMF inoculation (K=without AMF, A=Acaulospora sp., G=Gigaspora sp., and M=Mix of Acaulospora sp. and Gigaspora sp.) and Compost percentage (K0=without compost, K5=5% compost, K10=10% compost, and K15=15% compost). The results showed AMF and compost application improved growth compared to the quality of teak seedling. Inoculation of Gigaspora sp. with 5% compost gave the best responses for stem diameter and seedling quality index. The best leaves accretion was denoted by the seedlings that were inoculated by Mix AMF with 5% compost. Inoculation of Acaulospora sp. with 15% compost had better growth response for biomass. Root-top ratio and AMF colonization were shown in seedling that was inoculated by Gigaspora sp. with 15% of compost. Gigaspora sp. with 5% compost, therefore, is the best combination for increasing seedling quality.

This experiment aimed to identify the provenance and family responses to drought stress of Alstoniaangustiloba Miq. progeny trial. This experiment was arranged in randomized complete block design. The research used 2 factors, i.e. provenance (Banten, Muara Enim, Musi Rawas and West Sumatera) and family (43 families). In this experiment, family factor was nested in the provenance. The results showed that the addition of the lowestmortality occurred in Banten provenance (9.22%) and highest in Muara Enim provenance (19.44%). A total of 36families had additional mortality in the range of 4.17 to 33.33%. Height and stem diameter increment of all provenances decreased due to drought stress, which ranged respectively from 0.02 to 0.27 m/year and 0.02 to 0.05 cm/year. Ranking of height increment did not change before and after the occurrence of drought stress, i.e.with the following order provenance of Muara Enim, Banten, Musi Rawas and Solok. In the family level, ranking of height and stem diameter increment before and after drought stress were vary slightly.

Bogani Nani Wartabone National Park (TNBNW) is an important habitat for anoas, which represents genetic diversity of anoa species in the northern area of Sulawesi. Wild animals depend on their habitats for many things, including food. Food availability influences the growth and reproduction of any species. Food information is also important for area management as an input in habitat development activities, which are parts of in-situ conservation. The aim of this study was to investigate the types, abundance and diversity of anoa food plants in TNBNW. The study was conducted in three locations, namely Imandi Mountain, Gambuta Mountain and Sinombayuga Mountain ranging between 0 and 1600 mdpl elevations. Data were collected using line plot sampling method and food type observation was performed with plots size of 0.04 ha. Total observation plots in three research locations were 202, of which 90 plots were in Imandi Mountain and Gambuta Mountain, and 22 plots were in Sinombayuga Mountain. Data were analyzed descriptively and presented in tables. Food abundance was determined by total food plants found in every location. Natural plants food diversity used several indices, which were Margalef Richness, Shannon-Wiener Diversity Index and Evenness Index. The results showed that 35 species of food plants were identified. As many as 28 species of them including herbaceous plants, and seven species of woody plants. Some plant species have higher abundance, namely rofu (Elatostema sp.), rattan (Calamus sp.), and various types of fern.
