Abstract

The use of the Total Alkaline-Silica (TAS) method from Maitre (2002) has been a very important object for scientists involved in the world of volcanology for years. Much literature shows that the use of this method is generally acceptable and well used for naming volcanic rocks, although for certain volcanic rocks such as lamprophyres, for example, there are still limitations in the use of this method. The TAS method requires the results of rock chemical analysis in the form of total Alkaline content which is the sum of Sodium Oxide (Na2O) and Potassium Oxide (K2O) on one side and total Silica content (SiO2) on the other side, which means that without the availability of chemical analysis results for both components, the TAS method cannot be used or the method can still be used by modifying the components of the chemical analysis results with other components, in this case it will be tried to replace it with the magnitude of various data from logging. The purpose of this study depends on the availability of logging data in the area to be studied in various variations such as Nuclear, Electrical and Acoustic Logs with various crossplots from the available logs. The results of the various crossplots are then validated using core rock data that has been named using petrographic analysis based on the naming of volcanic rocks using the classification commonly used in the discipline of volcanology.

Abstract

Industri tahu adalah industri yang didominasi oleh usaha-usaha skala kecil dengan modal yang terbatas dan tersebar di seluruh wilayah Indonesia. Salah satunya adalah industri tahu Harapan Maju (HS) di Cimanggis, Depok, Jawa Barat. Industri ini masih menggunakan cara tradisional dengan membuang limbah ke sungai. Jika langsung dibuang ke sungai, limbah tahu dapat mencemari lingkungan. Oleh      karena itu sebelum limbah dibuang, sebaiknya dijernihkan terlebih dahulu untuk menjaga lingkungan. Salah satu metode penjernihan adalah dengan menggunakan bentonit dan karbon aktif ampas tebu. Bentonit memiliki kemampuan untuk menyerap zat organik yang baik dan mengikat padatan yang relatif kecil dalam air. Sedangkan karbon aktif ampas tebu berfungsi sebagai penjernih dan menyerap logam berat pada air limbah. Proses yang terjadi adalah proses adsorpsi atau proses pemisahan zat padat         dari fluida dengan jalan melewatkan fluida melalui medium penyaring atau septum sehingga zat padat akan tertinggal pada medium. Teknologi sederhana ini sangat efektif bila diaplikasikan dalam pengolahan air limbah industri tahu. Sebelum pengujian nilai BOD 714 mg/L, TDS 1129 mg/L, COD 1152 mg/L dan pH air limbah adalah 4. Pengujian dengan menggunakan kombinasi ampas tebu dan bentonit pada sampel 2c yaitu ampas tebu 1 gr dan bentonit 0.1 gr memberikan hasil yang terbaik, dimana     nilai BOD 142,8 mg/L, TDS 407 mg/L, COD 195,84 mg/L dan pH 6 yang memenuhi standar Permen LH no.51 tahun 1995.

Abstract

Kegiatan penyediaan air bersih merupakan salah satu kebutuhan pokok bagi masyarakat, mengingat air bersih adalah faktor penting dalam kehidupan dan kesehatan masyarakat. Semakin bertambahnya populasi penduduk ditunjang dengan aktifitas ekonomi yang semakin kompleks, juga berdampak pada strategi pelayanan kebutuhan akan air bersih dan pemaksimalan usaha untuk menghadirkan sarana air bersih. Masalah air bersih tidak hanya hadir di daerah-daerah terpencil yang belum tersentuh pembangunan, daerah perkotaan dengan jaringan infrastruktur PAM yang sudah memadai pun terkadang masih terkendala dengan aktifitas pencemaran air dan penggunaan air berlebihan yang tidak efektif dan efisien. Desa Sungai Dayo, Kecamatan Bahar Utara, Kabupaten Muaro Jambi, memiliki permasalahan air yang kotor dengan kandungan mangan dan besi yang tinggi. Selain tercemar limbah, hasil penelitian menunjukkan bahwa air tanah di daerah tersebut bersifat payau dan mengandung pengotor unsur mangan, besi, dan fluoride tinggi yang tidak baik untuk kesehatan, terutama kesehatan gigi. Berkaitan dengan hal tersebut kegiatan PkM ini menawarkan solusi alternatif yang bisa dipakai masyarakat dalam menyelesaikan permasalahan air bersih yaitu dengan menggunakan rekayasa material mineral lempung bentonit dalam pembuatan filtrasi air.

Abstract

The world of oil cannot be separated from drilling operations in extracting hydrocarbons from below the earth's surface. Drilling mud or drilling fluid is essential to the drilling process. Cibinong Oil and Gas Vocational School is a vocational school that has two study programs, namely, Oil and Gas Drilling Engineering and Oil and Gas Production Engineering. The laboratory assistants at the Oil and Gas Vocational School have limitations in explaining in detail about drilling fluids. Therefore, activity is necessary to increase insight and knowledge of drilling fluids, especially in supporting practical activities. The method used in this activity is the dissemination of knowledge about drilling mud accompanied by the practice of making a simple drilling mud mixture. Making drilling mud is carried out by comparing KCl polymer mud and polyamine as a shale inhibitor. This comparison is seen from the results of the physical properties of the mud produced, namely mud weight, funnel viscosity, plastic viscosity, yield point, 10-second gel strength, 10-minute gel strength, filtration rate, mud cake, and pH (acidity level). With this introductory activity, knowledge about drilling fluids for laboratory assistants and chemistry teachers as participants in PkM activities has increased. This increase in knowledge can benefit students who will continue their education at the undergraduate level in earth sciences at universities.

Abstract

In the last few years, exploration activities have experienced obstacles and have not attracted much attention from researchers in Indonesia. One of the basins in Indonesia that is still interesting is Salawati Basin in West Papua, Indonesia. Several studies related to petroleum systems have been carried out in this basin, especially those that control the migration of hydrocarbon in Salawati Basin. This research was conducted on three wells located in the western of Salawati Basin to evaluate the characteristics and the maturity of the source rock, especially the Sirga Formation. This formation is penetrated by wells MM-02, MM-03, and MM-04, by using the K-Means Clustering method to validate several parameter variations of the maturity level. K-means cluster performs data from various parameters of maturity level with predefined three numbers of cluster. The thermal evolution of source rocks can alter organic matter physical and chemical properties, converting it into hydrocarbon compounds. The selected maturity parameters have good sensitivity to the determination of thermal maturity including phenanthrene (P), in addition to the MPI (methylphenanthrene index) parameter which was obtained from mass chromatograms m/z 178 and m/z 192 based on the peak area of P and methylphenanthrene (MP). Based on the appearance of the crossplot, both Radke and Kvalheim Formulas show that the maturity in studied area is divided into three main zones: peak maturity zone, early maturity zone, and outliers. This study also found that increasing thermal maturity is correlativewith the increasing depth.

Abstract

This research aimed to determine the influence of side-slip velocity on subsurface displacement during seismic data acquisition. Anisotropy constants were used to determine the depth migration process before stack, which showed inadequate results after data validation. Therefore, the forward modeling of a medium, which comprised anisotropy constants of normal and offset raytracing was conducted to address this problem. The configuration of source to receiver were orthogonal and slant. The results showed that the migration process failed to resolve the geological structures of the position shifting. The configuration of source to receiver were orthogonal and slant. The results show the better continuity of slant and the influence of complex geological structures controls the position shifting, which could not be resolved by the migration process. It could be seen from the random distribution of the normal shift of group velocity and phase velocity, as well as the CDP – CRP shift. It produced wave azimuth rotation in a discontinuity plane, such as fault and anticline ridge. This azimuth rotation was strongly suspected to cause inaccurate anisotropy constants implementation in pre-stack depth migration process

Abstract

Uncertainty is often present in the relationship between physical property variables and the complexity increases, when mechanical properties are included. The problems becomes more interesting in cases, where fluid dynamics act as the primary contributing factor. Pore pressure changes is the main actor of every uncertainty of physical properties. Therefore, this study aimed to examine the influence of fluid dynamics on physical uncertainties of hydrocarbon reservoir. To achieve this objective, well data from production and enhanced oil recovery (EOR) operations between 1994 to 2007 were entangled. Specifically, 3D seismic data was incorporated to distribute physical and mechanical properties after well periodization. In this study, the impact of pore pressure changes on minimum horizontal stress from 1994-2017 was also examined. The results showed that changes in porosity were not significant, but variations in bulk modulus and Poisson's ratio remained observable. Furthermore, tensors field were not dominated by vertical stress, instead of horizontal stresses. Changes in pore pressure apparently had a significant impact on minimum horizontal stress. The increase of  minimum horizontal stress reached approximately one third of pore pressure change. Consequently, the stress regime transitioned from the strike-slip fault in 1994 to thrust fault in 2017, emphasizing a significant increase in the influence of horizontal stress. While water injection and oil production did not lead to significant changes in physical properties, the effects were evident in the variations of Poisson's ratio.

Abstract

This study aimed to investigate the effect of gold mining on soil properties. Soil samples were taken from the post-gold mining land, the property of PT Panca Logam Nusantara and PT Alam Buana Indonesia, and a nearby natural forest in Bombana, Southeast Sulawesi Province. The next step focused on specifying soil pH, total nitrogen (TN) and carbon (TC) concentration, C/N ratio, available phosphorus (P) concentration, cation exchange capacity (CEC), and exchangeable K, Na, Mg, Ca, Fe, Mn, Cd and Pb concentration, texture and spore amount, AMF resource and AMF colonization. The result shows that the pH in post-gold mining soil was higher than that in natural forest soil. Meanwhile, TN, TC, available P, and CEC of post-gold mining soil got lower compared with these of natural forest soil. The texture in the post-mining soil was clay loam, while that in natural forest soil was clay. Total of 10 AMF species belonging to five genera and three families were found in a post-gold mining area. Soil pH, CEC, soil texture, Mn, and total Fe had a negative relation with AMF colonization and spore count, while organic C, total N, C/N ratio, P2O5 and silt had a positive relation. Sand was proven to have a strong and positive correlation with the amount of AMF species. Adding organic matter and fertilization as well as applying mycorrhizal biofertilizers, were urgently required to support the effort in restoring post-gold mining soil.
