Abstract

ABSTRACT The Kulonprogo Mountains are mostly Tertiary volcano products that form a high morphology located on the western side of Yogyakarta. Each volcano generally forms volcanic facies and is followed by hypogeneous follow-up processes such as the hydrothermal alteration process that forms ore minerals. This research is a preliminary study to see the relationship between volcanic stratigraphy with the existence of hydrothermal processes and the type of mineralization in the southern Kulon Progo Mountains. The method that used is a qualitative analysis that combines morphology data and data from some previous study so that a comprehensive conclusion can be drawn. The results showed the presence of mineralization with epithermal type and indicate the existence of porphyry systems that associate with volcanic rocks that characterize the central to proximal facies. In the study area there is an indication of the relationship between volcanic stratigraphy and the presence of mineralization types. Mineral deposits that are located far from the indication of the eruption center tend to be of low sulfidation type while approaching the eruption center, the type of mineralization leads to high sulfidation. Mineralization systems in the Hargoejo, Gunung Agung and Kalirejo areas are interpreted to follow the Ijo Crown system while the Sangon Region mineralization system follows the Kukusan Hummock system. Not always high sulfidation epithermal deposits and porphyry are found in the central facies of volcanoes and low sulfidation epithermal deposits are far from central facies because in areas far from the center there can be intrusions that form a hydrothermal system so as to produce high sulfidation epithermal deposits.Research is still interpretive so it requires detailed field data, more complete laboratory data, the addition of parameters and other methods in further research. Keywords: volcanostratigraphy, volcanic facies, mineralization type, Kulon Progo

Abstract

Pencemaran perairan oleh logam berat tidak terlepas dari aktivitas manusia itu sendiri (Antropogenik) dimana manusia selalu memiliki kebutuhan akan suatu produk, dimana pengolahan suatu produk dapat menghasilkan logam berat. Merkuri (Hg), arsenik (As), timbal/timah hitam (Pb), kadmium (Cd), tembaga (Cu), nikel (Ni), dan khromium (Cr) merupakan logam yang berbahaya bagi lingkungan hidup. Logam berat yang semula masuk kedalam perairan dan menjadi kation-kation lambat laut akan mengendap menajdi sedimen, umumnya logam berat yang mengendap bersama dengan sedimen dasar perairan akan terdeposisi di berbagai fraksi ukuran butir sedimen, namun secara spefisik jejak logam berat akan didominasi pada ukuran butir sedimen halus (<63 um). Konsentrasi logam berat akan selalu berkorelasi dengan ukuran butir sedimen terutama pada ukuran partikel halus sehingga memiliki korelasi yang sangat kuat serta ukuran partikel sedimen dapat menyumbang terkait peningkatan konsentrasi logam > 80%. Faktor yang mempengaruhi jejak logam berat pada berbagai ukuran butir sedimen ialah ukuran butir sedimen itu sendiri, pH air, mineral penyusun sedimen, bahan organik, serta luas permukaan butiran sedimen. Kata kunci: Logam berat (Heavymetal), Ukuran, Korelasi, Sumbangan, Faktor.

Abstract

Bijih Emas yang terdapat di Dusun Sangon II, Kalirejo, Kokap, Kulonprogo telah ditambang dan diolah dengan menggunakan metode amalgamasi dari Tahun 1990 sampai dengan Tahun 2017 oleh para penambang tradisional/ Penambangan Emas Skala Kecil (PESK). Bijih Emas tersebut merupakan hasil mineralisasi mengendapnya unsur logam Emas di dalam urat-urat Kuarsa yang terkontrol oleh struktur yang berkembang di daerah tersebut berupa rekahan-rekahan/kekar. Penelitian ini dilakukan untuk mengetahui adanya kandungan Merkuri dalam bijih Emas dengan mengambil sampel bijih Emas yang ditambang. Sampel bijih Emas diuji dengan menggunakan Mercury Analyzer Lab 254 di Laboratorium Penelitian Dan Pengujian Terpadu (LPPT), Universitas Gadjah Mada. Hasil penelitian menunjukkan bahwa terdapat kandungan Merkuri secara alami pada bijih Emas. Kandungan Merkuri pada bijih dapat terjadi pada mineralisasi endapan hidrotermal pada tahapan epitermal, yang terjadi di dekat permukaan bumi, sehingga dapat disimpulkan bahwa bijih Emas yang terdapat di daerah penelitian merupakan hasil dari proses pengendapan logam pada larutan hidrotermal pada tahapan epitermal. Kandungan Merkuri yang terdapat pada bijih Emas secara alami dapat mempengaruhi keterdapatan logam berat Merkuri di lingkungan hidup daerah penelitian.

Abstract

Government efforts in order to cope with the increase in the extent of critical land, is the occurrence of changes in environmental baseline caused by natural and human behavior. The process of repairing degraded land in Indonesia is one of the efforts to reforest and cope with natural disasters, such as landslides. One of the activities that results in the criticality of an area is open mining which is not followed by immediate efforts to optimize reclamation. To rehabilitate degraded land used as industrial excavation land, it is necessary to choose the types of soil fertilizers that are able to grow in the open and contain nutrients and contain chemicals that are toxic to plants. After that careful efforts were made in implementing soil improvement. The form of repairs carried out by mixing limestone and chemicals.

Abstract

The government in the context of adding information on the wealth of natural resources in this connection is iron ore and nickel ore in Indonesia, as well as economic forecasts and analysis which are not periodically owned by the stakeholders. Data validation of iron sand and nickel resources has not been documented accurately because there is no coordination and synchronization of companies and associations - very diverse, different from other agencies or institutions. From the analysis it is known that the initial value of bauxite resources in 2017 amounted to 1.72 billion tons exploited by 1.15 million tons, the discovery of new exploration results amounted to 2.33 billion tons, to be the final balance of 4.45 billion tons with the price of bauxite resources of US $ 289.83 billion. New exploration results were 1.94 billion tons and the final balance was 5.65 billion tons, with a nickel ore price of US $ 29, the economic value of nickel resources was US $ 164.08 billion. The results of the analysis are expected to provide benefits as a database in the management of bauxite and nickel ore resources.

Abstract

In 2016 container flows at the Port of Tenau Kupang reached the target of 100,000 TEUs. The total loading and unloading of containers at the Port of Tenau Kupang was 115,705 TEUs, whereas in the previous year it was only 99,064 TEUs. The achievement of the container target is due to the passion of business people using containers as a tool for shipping goods on board, due to their high load capacity. The high flow of containers and the limited area of ​​container field facilities need to be balanced with good service management that can expedite the process of entry and entry of containers in the container terminal environment, so as not to cause high utilization of the stacking yard (Yard Occupancy Ratio / YOR). Therefore, this research focuses on evaluating the performance of YOR Port of Tenau Kupang and providing solutions to the evaluation results so that container loading and unloading activities run smoothly. The width of the container stacking field needs in Port of Tenau Kupang in 2017 is 25,271 m2, with a capacity of 23,745 m2 stacking field, so the YOR is 106.43%. This means that the YOR performance of the Port of Tenau Kupang is quite bad, because its achievement is above 10% of the performance standards set by the Director General of Sea Transportation by 60%. To improve YOR performance, the best scenario is to reduce dwelling time to 3 days. Keywords: Yard Occupancy Ratio/ YOR, dwelling time, containers, stacking yard
