Eo-Oligocene Oil Shales of the Talawi, Lubuktaruk, and Kiliranjao Areas, West Sumatra: Are they potential source rocks? Iqbal, M.; Suwarna, Nana; Syafri, Ildrem; Winantris, Winantris

DOI:10.17014/ijog.v1i3.198To anticipate the increasing energy demand, additional data and information covering unconventional fossil fuels such as oil shale must be acquired to promote the usage of alternative energy sources to crude oil. The Talawi and Lubuktaruk regions situated within intra-montane Ombilin Basin, and the Kiliranjao assumed to be a small intra montane basin are occupied by Eo-Oligocene sediments of Sangkarewang and Kiliran Formations, respectively. Field activity, geochemical screening techniques, and organic petrographic analysis, supported by SEM mode, are methods used. Most of the oil shale sequence is typically of an organically rich-succession comprising predominantly well-bedded, laminated and fissile, brownish to dark grey organic-rich shale and mudstone rocks. The exinite macerals within oil shale comprise mainly Pediastrum-lamalginite with minor cutinite, resinite, liptodetrinite, sporinite, bituminite, and rare Botryococcus-telalginite. Therefore; the oil shale deposits can be described as âlamositesâ. Minor vitrinite maceral is also recognized. TOC analysis on selected shale samples corresponds to a fair up to excellent category of source rock characterization. The hydrogen index (HI) for all samples shows a range of values from 207 - 864, and pyrolysis yield (PY) ranges from 2.67 to 79.72 mg HC/g rock. The kerogen is suggested to be of mixed Type II and Type I autochthonous materials such as alginite, with minor allochthonous substances. Oil samples collected appear to be positioned within more oil prone rather than gas prone. Thermal maturity of the oil shales gained from Tmax value and production index (PI) tends to show immature to marginally/early mature stage. A consistency in the thermal maturity level results by using both Tmax and vitrinite reflectance value is recognized. On the basis ofÂ SEM analysis, the oil shale has undergone a late eodiagenetic process. Thereby, overall, vitrinite reflectance agreeing with Tmax rates, are also consistent with the PI (production index) values and SEM result. By evaluating all the results of geochemical and organic petrological analyses conducted on shale lithologies (shale and mudstone), it can be concluded that the oil shales in those areas have a favourable potential for generation of shale oil or gas to be included as alternative energy resources in the future.

Penduduk Kampung Pasir Angling sebgian besar Â sebagai peternak dan petani. Mereka membuat kandang Â sapi secara Â tradisional. Kualitas kandang belum memenuhi syarat kebersihan.Â Fases sapi belum dimanfaatkan secara optimal, mereka membuang fases ke sungai Cikapundung yang menjadi sumber pencemaran, dilain pihak air sungai Cikapundung adalah bahan baku air minum PDAM Kota Bandung. Peningkatan kandang tradisional menjadi kandang bersih dan ramah lingkungan adalah tujuan dari pengabdian kami. Telah dilakukan upgrade sebuahÂ kandang sapi dari kandang tradisional berlantai kayu, menjadi kandang bersih berlantai plsester dilengkapi dengan saluran pembuangan dan bak tampungan feses. Uprage kandang mampu meningkatkan kebersihan susu, mengurangi ketergantungan terhadap pupuk buatan dan mengubah kebiasaan membuang limbah ternak ke Sungai Cikapundung menjadi bahan produktif Â pupuk Kascing yang ramah lingkungan

The research area is located in the Muara Teweh, North Barito, Central Kalimantan. The cocking coal deposits are well known as they were produced from this area.  Upper part of Tanjung Formation is target coal production. The study objectives are to analyze paleoenvironment and to determine the relative age of coal deposits based on palynological data. Preparing palinological analysis used standard procedure by hydrofluoric acid method.Palynomorphs data  grouped into six types of ecology, and the sequence is as follows ; fresh water and lowland (41,75 %), brackish water  swamp (30,10%), Peat and freshwater swamp (17,96%), marine element (7,77 %), back mangrove (1,46%) and upland element (0,97). Palmae pollen is very dominant, especially from freshwater and peat swamp that grow around coastal area i.e. Dicolcopollis, Proxapertites cursus, Proxapertites operculatus, Longapertites and Palmaepollenites kutchensis. Although marine  fossil found, but the frequency  less than one percent,  that was the  evidence of influence sea water to swamp area. The palynomorphs indicate the coal sedimented at upper delta plain.  Fossil index of relative age consist of    Proxapertites cursus, Proxapertites operculatus, Magnastriatites howardi Verrucatosporites usmensis, Retistephanocolpites , and Ixonantes type which refer to Late Eocene.

The Gunung Geulis block, Cikepuh Wildlife Nature is one of the natural areas which is considered as the habitat for various wildlife. The area are currently degraded due to the fire. Reconstruction of the vegetation in Gunung Geulis block was conducted as an effort to understand the history of vegetation, so that in the future it can rehabilitate the burnt forest area through reforestation activities in accordance with the initial conditions of the habitat (before burning). This study used a transect method for soil sampling and acetolisys method to know the diversity of the sedimented sub-fossil pollen. Based on the results in the five sampling's points, the 90 types of both sub-fossil pollen and spores of plants (i.e., 34 types of sub-fossil pollens (arboreal pollen), 40 types of sub-fossil pollen (non-arboreal pollen), and 16 species of sub-fossil spores) were observed at five sampling points in Gunung Geulis block. This indicates that the annual fire intensity in the Gunung Geulis block were relatively high. Indeed, the correspoding block is undergoing a secondary succession. The vegetation changes that occur can be illustrated by the diversity of the observed sub-fossil pollen and spores in soil.Keyword : Pollen, Spores, Vegetation Reconstruction, Gunung Geulis, Cikepuh.

Pollen and Foraminifera Approaches to Identify Sediment Sources In The River Mouth Mahakam East Kalimantan Winantris, Winantris; Jurnaliah, Lia

The central role of Mahakam River in the construction of Mahakam Delta is to supply sediment from terrestrial to the river mouth. The river upstream comes from Mount Camaru and the downstream part terminate at Makasar Strait. The surrounding area of the river is overgrown by wet tropical flora that produces pollen. The existence pollen in river sediments as an indicator that sediment came from terrestrial, and foraminifera as an indicator that sediment came from marine. The ratio changes of pollen to foraminifera show that there were differences of sediment source supply. The study was conducted at the river mouth. A shallow core, 200 cm depth, composed of sand and mud and sandy mud, from it taken vertically 11 samples to be analyzed pollen and foraminifera. Sample preparation was using standard methods acetolysis. Meanwhile, sample preparation of foraminifera using Hydrogen Peroxide method. Pollen found at all samples, but foraminifera only found in 8 samples. The data indicating that sedimentation process in the mouth of a river not only gets sediment supplies from terrestrial but also from marine. The quantity of pollen and foraminifera varies vertically. The frequency of pollen much higher than foraminifera that indicates of source sediments dominance came from terrestrial which carried by Mahakam river current. Sonneratia caseolaris pollen continuously found in all samples. Stictogongylus vandiemensis is species foraminifera the most common that followed by Ramulina confossa, both of them come from the sea particularly from the shallow sea.

Abstract- Two fossil wood were discovered from Sindangsari Village, Sajira District, Lebak Regency, Banten Province, Indonesia. They were preserved within tuffaceous rocks of the Genteng Formation in Early Pliocene age in littoral to terrestrial environment deposition. To identify mineral composition of the silicified wood, XRD analyser method was applied. Result of XRD analyses shows that both of fossil wood are Dryobalanoxylon sp. consist of quartz mineral with d value is 3.358 Å and 3.350 Å Keywords : Dryobalanoxylon, Early Pliocene, Genteng Formation, Quartz
