The study aims to determine the potential of earthquake that could lead to tsunamis in the Flores Sea. Furthermore, based on the potential of earthquake magnitude, can be known high run-up of tsunami in the southern coastal region of Bulukumba regency. The height run-up of tsunami can show the vulnerability of tsunami impact and eects spatially based on the eect of land function in the southern coastal area of Bulukumba Regency. To plan an eective mitigation scenario in the southern coastal area of Bulukumba Regency can be based on the vulnerability of tsunami impacts and eects. This study uses secondary data consisting of three data. The condition of land function and the density of community infrastructure is obtained basedon RTRW data of Bulukumba District and Satellite Bing Maps image data; historical data of earthquake events inthe Flores Sea from 1927 to 2016 from the USGS site, and BMKG; as well as topographic data. Field check activityon land function condition is done as a form of conformity of secondary data. The results showed that the potential of seismicity in the Flores Sea is high, with magnitude (M 7 SR) potentially causing tsunamis around it, not least Bulukumba Regency, South Sulawesi Province, Indonesia. The area of tsunami inundation in Bulukumba Regency is 13.617 km2. The coastal area of Ujungbulu sub-district is a dense residential area that has the highest risk to the tsunami with an estimated 3,331 km2 inundation. Land cover in Bontotiro sub-district dominated by vegetation with kerapatandengan interval distance of more than 3 m is seen able to reduce the tsunami with a height of 17 m and 25 m. Tsunami disaster mitigation scenario in Bulukumba regency is to make coastal area as conservation area of coastal forest (mangrove plant) that function as green belt of tsunamiwave holder.

The research aimed to discover the response of the growth of two spinach species on Nutrient Film Technique (NFT) hydroponic system and the concentration of the appropriate AB Mix solution on each species. The research was conducted in January to February 2016, at Green House, Faculty of Agriculture, Tadulako University by using Split Plot Design method. The main plot was red and green spinach, while the subplot was the concentration of AB Mix nutrient solution, namely 4 ml/L of water, 5 ml/L of water, 6 ml/L of water and 7 ml/L of water. The research findings reveal that AB Mix nutrient solution was generally very good to support the growth of spinach on NFT hydroponic. The green spinach had better response rather than the red one. There was no interaction between species and the concentration of nutrient solution. The good concentration of nutrient solution for green spinach is 6 ml/L. It was showed by the better growth of plant height on all age of plant, the more number of leaves, the canopy and the root (wet and dry) were heavier, while on the red spinach, 5 ml/L of concentration of nutrient solution resulted in the best growth, yet it was not significantly different from other concentration except on the parameter of plant height and the dry weight of plant canopy.

The field observation of this research was conducted from June 2005 – May 2007 in tropical rainforest at Lore Lindu National Park Central Sulawesi. The main objectives of this research were to study (i) the relationships between interception loss and rainfall properties and vegetation characters and to determine the dominant factors affected (ii) the effect of rainfall interception on energy flux and mass transfer and (iii) the dynamics of vertical energy flux under the forest and grass land. Rainfall interception was 36.34 % of gross rainfall in 200 events, Depth rainfall and LAI factors had strong effects on rainfall interception. The relationships could be expressed as Ic = 0.980+0.239P+0.035LAI (R2 = 0.78). The output of this equation was compared with Gash model and the observation value showed that deviation of the equation was 1 % and less than Gash model, so that equation gave as good result as Gash model gave. By considering the data requirements and calculation procedures it was concluded that this equation is applicable for interception prediction. Land use type had effects on radiative and energy balance. Net radiation (Rn) in the forest was 10.66 MJ/m2/day and higher than in the grass land where incident global radiation was similar. Vertical latent heat flux in the forest was 9.53 MJ/m2/day or 89.40% Rn in rainy day and 8.41 MJ/m2/day or 74.56 % Rn in dry day, on the other hand, in the grass land, sensible heat flux was higher than latent heat flux of all weather condition. Direct effect of rainfall interception on energy flux and mass transfer might be described that is needed latent heat 9.0 MJ/m2/rainy day to evaporate the rain intercepted of 3.69 mm/rainy day. Effect of rainfall interception had positive correlation with latent heat flux and the negative correlation with sensible heat flux.

ABSTRACT Schistosomiasis in Indonesia is caused by the trematode worm, Schistosoma japonicum, with the snail Oncomelania hupensis lindoensis as the intermediate host. The presence of these snails is an indicator of determining the habitat area for the intermediate host of schistosomiasis. The aim of the study was to map the distribution of snail habitat in the Lindu endemic area. An observational study with a cross-sectional design was conducted in August 2021. The study was conducted in two villages in the Lindu Highlands, Sigi Regency, Central Sulawesi Province. The number of snail habitats in the Lindu Plateau found 25 habitats, covering an area of 27,088 m2. Snail density and infection rate (IR) were found to be 27.06 snails/minute (IR 0.68%). Based on the research, it can be concluded that the distribution pattern of the snail habitat in Lindu was clustered in certain areas. Habitat in Anca Village was most widely found in neglected coffee plantation areas, and a small part in primary forest areas. Snail habitat in Tomado Village was mostly found in watersheds, parapa grass in swamp areas, and uncultivated rice fields. Environmental management that can be carried out by multi sectors are the creating of rice fields, the creation of fish ponds, and the diversion of community paths in the Lore Lindu National Park area that passes through the habitat of schistosomiasis intermediate snails. ABSTRAK Schistosomiasis di Indonesia disebabkan oleh cacing trematoda jenis Schistosoma japonicum dengan hospes perantara keong Oncomelania hupensis lindoensis. Keberadaan keong tersebut sebagai indikator penetapan daerah habitat hospes perantara schistosomiasis. Tujuan penelitian adalah untuk untuk memetakan distribusi habitat keong di wilayah endemis Lindu. Jenis penelitian adalah observasional dengan desain potong lintang yang dilakukan pada bulan Agustus tahun 2021. Penelitian dilakukan di Desa Anca dan Tomado Kecamatan Lindu Kabupaten Sigi, Provinsi Sulawesi Tengah. Jumlah habitat keong di Dataran Tinggi Lindu ditemukan 25 habitat, seluas 27.088 m2. Kepadatan keong dan tingkat infection rate (IR) ditemukan sebesar 27,06 keong/menit (IR 0,68%). Berdasarkan penelitian dapat disimpulkan bahwa pola persebaran habitat keong di Lindu adalah mengelompok/clustered pada daerah tertentu. Habitat di Desa Anca ditemukan paling banyak di daerah kebun kopi yang terabaikan, dan sebagian kecil di daerah hutan primer dengan kanopi tertutup. Habitat keong di Desa Tomado paling banyak ditemukan di daerah aliran air, parapa, rawa, dan sawah tidak diolah. Manajemen lingkungan yang dapat dilakukan oleh lintas sektor yaitu pencetakan sawah, pembuatan kolam ikan, dan pengalihan jalur masyarakat dalam Kawasan Taman Nasional Lore Lindu yang melewati habitat keong perantara schistosomiasis.
