POTENTIAL OF METAL MINERAL RESOURCES IN MOUNT GOGOREA WAHLUA FORMATION BURU ISLAND

Geologically, Buru Island is composed of quite varied rocks, both in the form of sedimentary rock, igneous rock and metamorphic rock produced by subduction and magmatism and sedimentation activities. This is why Buru Island has quite a variety of potential metal and non-metallic mineral resources. The Wahlua Formation is the most widely distributed rock formation on Buru Island, but until now the petrographic, geochemical characteristics, and potential geological and mineral resources in this formation have not been studied in detail. The aims of this study were (1) to obtain data on the petrographic and geochemical characteristics of the rocks at Mount Gogorea, and (2) to determine the potential of metal minerals at the Gogorea location. The research was carried out at 4 observation points and 4 rock sampling points. Identification of petrographic and mineral characteristics was carried out megascopically and microscopically. Rock geochemical data were obtained using the AAS and ICP OES methods. The main rocks that make up the Geology of Mount Gogorea in the Wahlua formation are light-colored quartzite, granuloblastic texture, and non-foliated structure, various colored schist (reddish-brown-fawn and dark gray), lepidoblastic texture, foliated-schistose structure with mica as constituent minerals, phyllite greenish-gray, brownish to light in color, crystalloblastic texture with a smooth surface, and foliated-phyllitic structure, minerals making up mica, quartz, chlorite, and dark gneic rocks (greenish gray, dark gray, dark green), granoblastic texture and foliated-gneissic structure, with minerals in quartz, mica and hornblende rocks. The levels of precious metal Au were 16.7 ppm and 16.4 ppm, Hg was 2.49 ppm, As was 17 ppm while the highest base metal content was Mn at 925 ppm. Potential metal minerals at the Mount Gogorea location include precious metals (Au, Hg and As) and base metals such as manganese, zinc, barium, lead, copper and nickel. The presence of Au elements in rocks is associated with the levels of other elements, namely Ba, Co, Cr, Cu, Fe, La, Mn, Ni, Pb, Sr, and Zn.

The potential of legume cover crops and soil microbes for gold mine tailings revegetation

Mercury (Hg) is commonly utilized in artisanal gold mining on Buru Island; the Hg-contaminated tailing possibly contaminates the agricultural land nearby. In general, tailings contain very low organic carbon and plant nutrients but are high in mercury and have extreme soil acidity. The objective of this study was to observe the growth of various legume cover crops (LCC) and the change of Hg in tailing inoculated with <em>Azotobacter-Trichoderma</em>. The field trial was conducted on Buru Island of Maluku by using a split-plot design with three replications. The main plot was LCC species, composed of <em>Centrosema pubescens</em> (CP), <em>Mucuna </em>sp.<em> (</em>MC), and <em>Crotalaria </em>sp. (CR); the subplots were microbial inoculants composed of two formulations of <em>Azotobacter-Trochoderma</em> inoculants. The results showed that the <em>Mucuna </em>sp. and consortia <em>Azotobacter-Trichoderma</em> (2:1) had the highest survival rate in the tailings and Hg uptake by 8.83 mg kg<sup>-1</sup> per plant. Consortia <em>Azotobacter-Trichoderma</em> inoculant with the composition of 2:1 (v:v) was able to increase soil pH, total bacterial population, LCC biomass, and Hg uptake by LCC plants. The highest Hg removal effectivity was observed in the plot treated with <em>Crotalaria </em>sp. and in a plot with <em>Azotobacter-Trichoderma</em> (2:1), which was 34.0% and 33.6%, respectively.

PENINGKATAN KAPASITAS MASYARAKAT TRADISIONAL DALAM MENGGUNAKAN PERILAKU SATWALIAR SEBAGAI INDIKATOR PHENOMENA ALAM

Indigenous peoples who have lived in the Maluku Islands since their ancestors have applied various forms of local wisdom to the conservation of natural resources and the environment around them. As coastal communities who live on small islands separated by the sea, there are various limitations, especially communication and transportation which are determined by the season. The community seeks to know the dynamics of natural changes through various life experiences known as NANAKU. The layout of the island greatly determines the application of a local wisdom, so that what is done by the people in the Southeast Maluku Regency is different from on the islands of Seram or Buru Island. The wildlife on Seram Island and Buru Island are different from the endemic wildlife on the Aru Islands. The problems faced by small island communities are transportation, communication of science and technology. Wildlife as God's creation must be guarded and protected from extinction because it has important benefits for our lives. Wildlife can be used as an indicator (Nanaku) to find out natural phenomena around us. The role of foresters and ecotourists in motivating rural communities is needed so that environmental components, especially wildlife, can be put to good use.

Chemical characterization, total starch, amylose and resistance starch of local cocoyam in Maluku, Indonesia

Tubers are a potential source of carbohydrates due to their high starch composition with various benefits in the food and non-food industry. Meanwhile, cocoyam (Xanthosoma sagitofollium) is one of the tubers with high starch potential. Therefore, this study aimed to characterize the chemical properties, total starch, amylose, and resistant starch of local cocoyam from several locations in the Moluccas. These locations include Buru Island, Saparua Island and Saumlaki Island, the three locations are separated by the ocean. The starch was extracted using the wet method while the chemical analysis was carried out on the moisture, ash, fat, protein, phosphorus, and carbohydrate contents, as well as total starch, amylose, and resistant starch. Data were analyzed by means of variance (ANOVA) at = 0.05. The significant difference that occurred was continued with Duncan's test (α = 0.05). The results showed that the three starches were significantly different from one another, which implies that the growing location affected the chemical components, as well as the total starch, and amylose while the resistant starch was not significantly different. Based on the results, the growing locations affect the chemical contents but not the resistant starch.

Breach of Contract Settlement of Quasi Equity Agreement Between Investor With Indigenous People Soa Nacikit Migodo at Buru Island

Indigenous lands belonging to indigenous peoples are regulated by their respective customary laws. The land is seen as something very valuable and must be defended by the indigenous people. Customary land is land belonging to the customary law community unit.

Rice yield grown in different fertilizer combination and planting methods: Case study in Buru Island, Indonesia

Abstract Rice productivity in the tropics largely depends on fertilizers as soils are commonly low in nitrogen and phosphorus. Some farmers in this region cultivate rice using the hand-broadcast method, which has resulted in a low yield. Therefore, this on-farm experiment was conducted to compare the performance and yield of broadcasted and transplanted rice production systems under different fertilizer combinations. The experimental was set up in a split plot design with six combination treatments and seven replications. The main plots were planting methods comprised of transplanting and broadcasting. The subplots were a combination of NPK fertilizer, urea, and biofertilizer (BF) with and without compost, while the control treatment was NPK fertilizer and urea. The BF contained nitrogen fixer bacteria and phosphate solubilizer microbes. The results showed that fertilizer combination increased shoot height, root length, shoot and root dry weight (RDW), root-to-shoot ratio (R/S), tiller number, 1,000-grain weight, and yield but did not affect clump number. In addition, the planting method affected the parameters except for R/S and 1,000-grain weight. The yield of transplanted rice grown with NPK fertilizer and urea was 17.5% higher than that of the broadcasting method. Incorporation of chemical fertilizer combined with compost and BF resulted in a comparable yield; transplanted rice yield was only 2.18% more than broadcasted. This showed that diverse fertilizer application is needed to minimize the yield gap between broadcasted and transplanted rice.
