Abstract

One of the prospects for a wealth of geological resources that can be utilized for the benefit of mankind is manganese metal mineral resources. In Anabanua Village, especially at the research location, there is an indication of manganese mineralization that the type of rock carrying the mineralization is not yet known. The purpose of this study was to determine the chemical elements of metallic minerals, mineralogy, and types of mineralization-carrying rocks, as many as three samples in the form of chunks, which were analyzed using megascopic analysis methods identifying the texture and structure of carrier rocks, XRD (X-Ray Diffraction) analysis minerals, and XRF (X-Ray Fluorescence). The characteristics of manganese mineralization carrier rocks consist of metallic elements Mn (0.046%-20.455%), Fe (1.555%-3.673%), and nonmetallic elements SiO2 (11.403%-48.165%), K2O (0.398%-4.177%). Mineralogy of manganese mineralization carrier rocks are roeblingite (Pb2Ca6Mn2+(Si3O9)2(SO4)2(OH)2·4H2O), rhodonite (CaMn3Mn[Si5O15]), diopside (CaMgSi2O6), calcite (CaCO3), kieserite (Al, Ga)2(GeO4)(OH)2), zeolite (Mn2O.Al2O3.xSiO .yH2O), and palygorskite ((Mg, Al)2 Si4O 10(OH)·4H2O). Manganese mineralization host rocks are determined by referring to the SiO2 (%weight) and K2O(%weight) diagrams to produce basalt igneous rock types.

Abstract

Bauksit terbentuk dari batuan yang mempunyai kadar aluminium (Al) nisbi tinggi, kadar besi (Fe) rendah dan tidak atau sedikit mengandung kuarsa (SiO2). Bentuknya menyerupai tanah liat/cellular dan kadang-kadang berstruktur pisolitik. Secara makroskopis bauksit berbentuk amorf, kekerasan bauksit berkisar antara 1-3 Skala Mohs dan berat jenis berkisar antara 2,5-2,6. Bauksit merupakan bahan heterogen yang mempunyai mineral dengan susunan terutama dari oksida aluminium, yaitu berupa mineral gibbsite (Al2O3.3H2O), mineral boehmit (Al2O.3H2O), mineral diaspor (Al2O3.3H2O). Secara umum bauksit layak tambang mengandung Al2O3 sebanyak 45-65%, SiO2 1-12%, Fe2O3 2-25%, TiO2 >3%, dan H2O 14-36%. Persentase unsur bauksit akan menentukan langkah selanjutnya seperti perhitungan cadangan dan perancangan metode penambangan. Kandungan bauksit pada daerah penelitian adalah aluminium (Al2O3), besi (Fe2O3), silika (SiO2) dan titanium (TiO2).

Abstract

Pengolahan blending limbah biomassa cangkang sawit dan tempurung kelapa dalam secara pirolisis menghasilkan produk asap cair sebagai produk utama dan chart, arang sebagai produk samping. Dimana asap cair imi yang memiliki kandungan utama yaitu senyawa fenol, karbonil dan asam. tujuan untuk Mengetahui presentase rendemen asap cair yang dihasilkan setiap gram limbah biomassa cangkang sawit dan tempurung kelapa dalam, karakteristik senyawa yang terdapat dalam asap cair pada limbah biomassa cangkang sawit dan tempurung kelapa dalam, Mengetahui efektifitas asap cair sebagai intektisida organik. Preparasi sampel cangkang sawit dan tempurung kelapa dalam kemudian diblending dengan variable dan rasio terstentu. Selanjutnya metode pirolisis dengan variable suhu pirolisis. Asap cair dan chart kemudian asap cair diuji kimia dan fisik selanjutnya diaplikasikan untuk pembasmian serangga. Asap cair dari sampel blending limbah biomassa cangkang sawit dan tempurung kelapa dalam bahwa persen rendemen pada asap cair dengan 1000 gram sampel hasilnya terus meningkat secara signifikan di mana semakin banyak komposisi tempurung kelapa maka semakin besar persen rendemennya. Asap cair ini digolongkan asap cair grade C, yang berwarna coklat pekat dan berbau asap cukup keras. Karakteristik produk asap cair (viskositas, pH, massa jenis dan kadar asam asetat) yang dihasilkan dari blending limbah biomassa cangkang sawit dan tempurung kelapa dalam dengan rasio massa 0 : 100, 25:75, 50:50, 75:25, dan 100:0 dimana sampel tersebut telah memenuhi standar mutu asap cair spesifikasi jepang. Produk pada sampel cangkang sawit dan tempurung kelapa dalam memiliki efektifitas asap cair sebagai intektisida organik sangat baik dapat mematikan serangga/hama dengan waktu yang singkat.

Abstract

Factors influencing the content of asphalt is the process of formation, moisture content and the type of reservoir rocks, then to do the research on the characteristics of asphalt based on reservoirnya rocks. The purpose of this research is to know the physical nature of Asphalt Buton Rock based on reservoirnya. The method used is the sokhlet method. The data used is data of rocks reservoir site I and II, the physical properties of the data of the asphalt. Of research results obtained at the location I have rocks limestone reservoir with poor porosity features have higher levels of bitumen (23-47%), the asphalt is more dense and hard, CaCO3 content was higher (86,66%) whereas in a location that has a reservoir rock II sandstones with physical characteristics of good porosity have lower levels of bitumen (20-40%), the asphalt is relatively more malleable, a higher SiO2 content (17,06). From the results it can be concluded that the physical nature of asphalt location I have poor porosity and physical properties II location has good porosity, on the location of research levels obtained 20-47%.
