Abstract

China and ASEAN have long history on their relationship. One of ASEAN countries, Indonesia, along with China are two big countries in Asia with similar national interests and objectives in partnership, which are peace and prosperity of G20, APEC, 10+1, and 10+3, in which Indonesia is an active participant. One of the cooperation between China and ASEAN is through education. Indonesia may promote student exchange as well as proposing the idea of students exchange in various forums such as ASEAN-China free-trade, culture, tourism, education and many others. However, the data shown that the proportion of ASEAN students in China do not reflect the proportion of population of each ASEAN countries.  Indonesia, the largest country by population, only sends the second biggest number of students to China behind Thailand, which puts the most students in China Education.  This paper discusses the ups and downs of Indonesia-China relationship in education. SWOT analysis is used to see Indonesia-China relationship in the perspective of ASEAN. It can be concluded that cooperation among countries is inevitable measure facing the more challenging world. However the rough past has created mistrust and prejudice on both sides. But the need to collaborate has shown to be beneficial in promoting education cooperation.

Abstract

Rock size distribution is plays an important role in mining unserpentinized peridotite of Sorowako laterite nickel deposite. The increasing of Rock size will reduce mine recovery and make mining operation become more expensive. To outlining the Rock size distribution, a model generated from RQD have been used to classified rock size distribution into 4 unit is WT 1, WT 2, WT 3, and Infracture. The purpose of this study is provide an integrated and detailed information about the actual size of boulder in West Block and distribution of rock boulder. Research areas are in the concession area of West Block of PT. Vale is Hill X, Hill Y, and Hill Z. The research methods used by based on the method of RQD and data processing base on the drill point. Megascopic observations of rock types in the study area is igneus rock peridotite with composition of mineral dominantly by piroksin, olivine, serpentin and opaq. From the results of the data analysis and identifier of each element laterite zona through surface geological mapping Laterite zone of research area can be divided top soil, limonite zone, saprolite zone and bedrock.Keywords: West block of PT.

Abstract

This study were conducted in survey method. Four stations were established with three replication of each sampling station. It revealed that oil content in water ranged from (0.4391 – 0.7973) ppm. The highest epiphytic diatom density on the seagrass leaves oppeared in station 4 which accounted 366 ind/cm2, while the lowest 132 ind/cm2 found in station 2. During the study, epiphytic diatom species most commonly found are Isthmia sp, Navicula sp, Skeletonema sp, Ulothrix sp, dan Synedra sp. Statistical analysis showed the oil content and epiphytic diatom density correlation were weak with coefficient of (0.05)Key words : Rupat Utara Water, Oil Content, Epiphytic Diatom

Abstract

DOI:10.17014/ijog.3.2.139-147The development in modern-high technology application is growing rapidly, resulting in the constant supply of critical metal and rare earth elements (REE). Currently, resources of these elements are restricted and new source of these elements need to be discovered accordingly. Scandium (Sc) as one of critical metals is an important metal for electrolyte of solid oxide fuel cells and other advance technology. In addition, REE are the important elements in the use of permanent magnets and rechargeable batteries. This manuscript reports an overview on the possibility of scandium and rare earth element occurrences in Sulawesi. Sc is concentrated in limonite layers in Soroako ultramafic rocks as a result of Fe3+ site substitution of mafic minerals (pyroxene, amphibole, etc.) during a laterization process. REE are enriched in association with clay minerals in B horizon from heavily weathered granitic rocks in Palu and Masamba, suggesting the possibility of ion-adsorption style mineralization. The lateritic soil of the ultramafic rocks and the weathered crusts of the granitic rocks in Sulawesi could be the potential sources of scandium and rare earth elements, respectively.

Abstract

Exhumation and tectonomagmatic processes of the granitoid from Sulawesi were discussed using petrochemistry (e.g. petrographic and major element compositions) and geothermobarometry data (mineral chemistry data). Detailed petrographic observations were conducted to determine the mineral composition, texture, and structure of the granitoid rocks, whereas the whole rock composition were determined using XRF method, and the mineral chemistry was analyzed using Electron Microprobe Analyzer (EPMA). The granitoids are classified as calc-alkaline, metaluminous I-type. Pressures of 0.91 to 1.2 kbar and emplacement depths of 3.2 to 4.3 km at temperatures of 677 - 729°C were estimated for Mamasa Pluton. Whereas Masamba Pluton was emplaced at pressures of 2.3 to 2.8 kbar, temperatures of 756 - 774°C, and emplacement depths of 8.2 to 10 km. Moreover, Lalos-Toli and Sony Plutons were emplaced at temperatures of 731 to 736°C and 601 to 609°C, respectively. The pressures varying from 3.1 to 3.3 kbar and 3.2 to 3.4 kbar, equate to an emplacement depth of 11.3 and 11.6 km, respectively. Gorontalo Pluton emplaced at temperatures of 662 - 668°C with the pressure range from 2.6 to 2.7 kbar, is equivalent to 9.3 km deep. Varied oxidation state (ranging from -14 to 19) is inferred from the mineral assemblages, showing a strong association with highly oxidized I-type series granitic rocks. The exhumation rate estimation shows that Mamasa and Masamba Plutons were exhumed respectively at a rate of 0.37 and 1.6 mm/year, whereas Lalos-Toli and Sony Plutons at 1.4 and 2.7 mm/year, respectively. Gorontalo Pluton located in the Northern Sulawesi Province was exhumed at 0.42 mm/year. The rapid exhumation rate of Sony Pluton is attributed to the active vertical movement of Palu-Koro Fault Zone which has been active since Pliocene. It shows that faulting may play an important role in differential exhumation of intrusive bodies in the orogenic belt.
