Agricultural productivity in Buru Island, Maluku is threatened by tailings which are generated from formerly gold mine in Botak Mountain in Wamsait Village. Gold that extracted by using mercury was carried out in mining area as well agricultural field. High content of mercury in tailings and agricultural field pose a serious problem of food production and quality; and further endangers human health. The purpose of this research was to determine the contaminant level of mercury in tailing, soil and its accumulation in edible part of some food crops. Soil, tailing and plant samples for Hg testing were taken by purposive method based on mining activities in Waelata, Waeapo and Namlea sub district. Six soil samples had been analyzed for their chemical properties. Total mercury levels in tailings and plants were measured by Atomic Adsorption Spectrophotometer. This study showed that agricultural field where tailings were deposited contained Hg above the threshold but agricultural area which is far from hot spot did not. Most edible parts of food crops accumulated mercury more than Indonesian threshold for mercury content in food. This evidence explained that tailings deposited on the surface of agricultural field had an impact on soil quality and crop quality. Tailing accumulated on soil will decreased soil quality since naturally soil fertility in agricultural field in Buru is low.

Bioherbicide is important approach for sustainable farming practices. One of plant that has potentially as bioherbicide, which is environmentally safe, is mango. Mango leaf extract is useful as bioherbicide because it produces allelochemical compounds, which could inhibit the weed growth. This research was designed to study the effect of several mangoes species leaves extract to control dominant weed (amaranth). Split plot design was implemented using mango species (S) as the main plot; S1 (Mangifera odorata Griff.), S2 (Mangifera foetida Lour) and S3 (Mangifera indica L.). While the sub plots were concentrations of mango’s leaf extract (K), that included 0, 500, 1000, 1500, and 2000 ppm. Results of the research showed that all parameters of weed growth (amaranth) were inhibited along with the increase of concentration of the mango’s leaf extract. The results also showed the significant inhibition of amaranth’s dry weight. Among three species of mangoes, M. indica L. showed the best inhibition mechanism to the amaranth weed, which significantly suppressed the weed growth on just 1000 ppm concentration.

Geochemistry of ultramafic rocks in the Latowu Area of North Kolaka Regency, Southeast Sulawesi has been investigated with the aim at deciphering of mineral characteristics, chemical composition and their potential use as carbon dioxide storage. Mineralogy was characterized by both scanning electron microscopy (SEM) and X-ray diffractometry (XRD); whereas bulk rock and mineral chemistry were analyzed by means of X-ray fluorescence spectrometry (XRF) and Electron probe microanalyzer (EPMA) respectively. Results of analyses show that lizardite is predominant serpentine mineral present, followed by chrysotile and trace amount of magnetite. Remnants of olivine and pyroxene were detected in some samples but they have been pseudomorphicly replaced by serpentine. Serpentinization of Latowu ultramafic rocks has led to decrease in grain size and density. Lizardite is characterized by fine grained particles with higher in iron. The higher Mg and Fe of the rocks indicate a suitability as feed materials for carbon dioxide sequestration. Mineral and chemical properties of ultramafic rocks have significant role in evaluating the feasibility of mineral carbonation.

Coastal area activity on human exploitation greatly affected aquatic ecosystems. Land changes disturbed the level of soil stability, soil will be easily eroded by the flow of water, the surface tide ran off to the sea. North waters of the island of Bengkalis is a place boiling down to several rivers, including the river Jangkang and river Liung. The rivers have affected the concentration of total suspended solid (TSS) in the strait waters of North Bengkalis Island. This research demonstrated water sampling by using sampling point determined by purposive sampling method mixing the layer of water depth ratio. The results based on satellite imagery data showed that TSS was quite high in the West season period until the transition period I (West to East) with a large concentration value of 200 mg / L. For the lowest TSS concentration occurred in the East season i.e., between 0 - 200 mg/L. TSS concentrations that dominated in the East season ranged from 51 to 75 mg/L This value was higher than the TSS concentration of field data analysis, i.e., between 23 - 39 mg/L. Changes of coastal coastline of North Bengkalis during the last 20 years continue to change the size of the land area, with a land area of 131 ha lost.

Rote Island is one of the islands in southern of Indonesia. This region experiences very high geological and geodynamic processes. This is evidenced by the abundance of seabed rising, and there is a dead sea lake area that has a higher salinity than the sea. Biodiversity on Rote Island has endemic and unique flora and fauna. This study aims to create an integrated system of inland waters resources on Rote Island with a multidisciplinary approach. Inland water resources on Rote Island number more than 80 lakes and ponds. An inland water resource on Rote Island is a saltwater environment. The extraction of geobiophysical information on inland water resources is needed by studying various aspects of multidisciplinary. The aspects studied are limnology, water quality, conservation of forest resources, geology, geodynamics, water resources, geodesy and geomatics engineering. All geobiophysical information needs to be integrated into an integration system. This is useful for efficiency and effectiveness in the utilization of data and information. This integration system (geovisualization) is in the form of WebGIS and storytelling maps. This integration system is dynamic so it can update its latest spatial information. This integration system can be used to promote Rote island tourism. This integration system can be accessed via the website geopark4rote.com. This integration system can be applied in other regions so reached one map policy and a system for inland water resources will be realized in Indonesia.

This research was conducted with the aim of studying land use change and evaluating the impact of land conversion on land capability in Tirtomoyo District of Wonogiri Regency. This research employed a descriptive, explorative method by utilizing SIG Arc Map 10.1 and Google Earth Pro software. The analysis of land use change, especially agricultural land, was conducted through visual interpretation of Google Earth Pro satellite imaging in 2004 and 2016. A ground check was done by land survey. Soil sample analysis was done to determine land capability class. Based on research results, it was found that eight locations experienced land use change. Location 1 had changed from secondary forest to moor, location 2 from moor into farm, location 3 from bushes into paddy field, location 4 from paddy field into farm, location 5 from paddy field into farm, location 6 from moor into paddy field, location 7 bushes into moor, and the location 8 from paddy field into farm. Land use changes showed different results of changes in soil physical properties based on soil characteristics at each type of land use. Changes in land use generally had less impact on land use class change. Locations 1, 6, and 7 did not experience changes in land capability class, but there were changes in the sub-classes of land capability. Locations 2 and 8 did not experience changes in class or sub-classes of land capability but sites 3, 4, and 5 indicated changes in land capability class by inhibiting factors namely permeability class in a paddy field.

A study that was aimed to elucidate the effect of adding pineapple liquid waste and cow dung compost in increasing the availability of soil N, P, K, contents of N, P, K in pineapple leaves and growth of pineapple plant in an Ultisol was conducted in Central Lampung. The study consisted of two steps, i.e. incubation of pineapple liquid waste with cow dung compost in the soil, and planting pineapple by adding pineapple liquid waste and cow dung compost. Treatments tested in experiment 1 (laboratory incubation experiment) were combinations of pineapple liquid waste (L) and cow dung compost (K). Changes of soil chemical characteristics were observed at 15, 30, 45, and 60 days. Three best treatments of experiment 1 were selected for the experiment 2 (plant growth experiment in a glasshouse). Two control treatments were included in experiment 2. N, P, and K contents in pineapple leaves as well as and pineapple root length were observed at 30 and 60 days. Results of the first experiment showed that addition of pineapple liquid waste and cow dung compost significantly increased soil pH, availability of soil N, P, and K compared to controls at 15, 30, 45, and 60 days. Addition of 20 t cow dung compost/ha and 20,000 L pineapple liquid waste/ha (K3L3 treatment) resulted in higher values of soil pH, total N, available P, and available K than the control. Results of the second experiment showed that the addition of pineapple liquid waste and cow dung compost gave no significant effect on the growth of pineapple plant, but the addition of 20 t cow dung compost/ha and 10,000 L pineapple liquid waste/ha (K3L2 treatment) gave optimum growth compared to other treatments at 60 days. The K3L2 treatment also had higher pineapple leaf nutrient content, compared to control.
