Published: November 2019

Kepala Burung PSC is located at onshore portion of Salawati Basin. The PSC area is divided into two area(s) namely Walio Area and Arar Area at the south and north, respectively. Numerous exploratory wells had been drilled at Walio Area which resulted several economical discoveries of oil reservoired within the reefal Kais Formation and the overlying mixed-silisiclastics carbonate of Lower Klasafet reservoirs namely U-Marker and Texturalia Intervals. The latest discoveries at this area was in 2010 by the drilling of North Walio-1 well which encountered oil reservoirs within Kais Formation. With consideration of exploration success ratio, proven petroleum system elements and thebroad distribution of Miocene Kais and Lower Klasafet; exploration in this area is still promising. Moreover, twothree-dimensional (3D) volume of seismic which acquired in 2004 and 2007 are beneficial in improving the geological understanding in this area. This study is providing seismic interpretation which weighted to seismic facies analysis within Kais-Lower Klasafet reservoirs and the depositional model of these two associated reservoirs. Seismic facies analysis within the studied reservoirs are focused to reflection characteristics such as; seismic reflection termination, continuity, amplitude, frequency and internal reflection configuration. The internal seismic reflection characteristics are compared between the successful and unsuccessful exploration drilling. Subsequently, a sketched depositional model at the times of Kais and Lower Klasafet deposition is constructed. Three seismic reservoir facies are recognised in this area; pinnacle reef-patch reef which associated to narrow topography high(s), reefal carbonate bank which associated to broad or extensive topography highs, and drowning package of carbonate-mixed-silisiclastics at the top of Kais reef(s). These types of carbonates are interpreted to be deposited within five stages of major sea level rise. The antecedent topography of the reefs is mapped to be used as reef fairways in Salawati Basin, which means will be tied to neighbouring northern Arar Area and the other adjacent areas.

Temporal change of Barujari Volcano magmatic process: Inferred from petrological study of erupted products since AD 1944
Authors: Abdul-Jabbar G , Rachmat H , Nakagawa M
Published: November 2019

Barujari volcano is an active volcano located in Lombok Island Indonesia. The volcano is a part of post caldera stage of Rinjani volcano. The volcano shows strombolian to vulcanian type eruption and produces mainly lava with basaltic-andesitic composition (54-56 wt% SiO2). The volcano actively erupts several times during past 70 years. However, temporal change of its petrological characteristic has not been discussed. This paper discusses petrological changes in Barujari volcano erupted material through time from AD 1944 to 2015. Total 31 samples erupted from AD 1944, 1966, 1994, 2004, 2009, and 2015 are observed and analyzed with XRF method. Our study shows that most of samples can be classified into basaltic trachy-andesite with 53-56 wt% SiO2. All samples show nearly linear trend in harker diagram and shows no systematic change through time. However, AD 1966 shows curved trend and more silicic composition compared to other samples. We suggest that magma mixing with repeated injection of more mafic magma play an important role in producing most of basaltic-andesitic Barujari lava as suggested by linear trend of harker diagram and appearance of heterogeneity in groundmass. AD 1966 samples also contain evidence of magma mixing but curved trend does not suggest simple mixing processes. Appearance of olivine-poor samples in SiO2 rich AD 1966 samples might suggest more close system differentiation process that mixed with common Barujari products.
Facies and Architectural Element Analysis of Braided Fluvial Succession: The Tertiary Sawah tambang Sandstone, Sawahlunto, Indonesia
Authors: Gusti U. K. , Susilo B.K.
Published: November 2019

The Sawahtambang Sandstone Formation of Sawahlunto, Indonesia has hitherto never been studied in detail to ascertain its depositional processes and its palaeoenvironment. The Sawahtambang Sandstone has more than 394 m thickness which consists of conglomeratic sandstone, sandstone, and clay-silt intercalation within which six lithofacies types (St, Sp, Sh, Ss, Fl, and Fm) appear creating iterated fining upward sequence. Herewith, this paper aims to replenish the avantgarde sedimentological interpretation of the Sawahtambang Sandstone in the intermontane basin of Indonesia based on outcrops along the Trans-Sumatra Highway. The study is attained through facies identification based on stratigraphic measuring section or outcrop profile, studio analysis consists of log analysis and superposition reconstruction, and architectural element delineation according to facies association. Structures in clay-silt facies consist of lamination and fissile whereas in the sand grained include planar and trough cross-bedding, planar lamination and granule lag, which depicts a lower-flow-regime sand channel. The architectural elements that made from facies association are identified into five distinct elements (multi-storey channel, single storey channels, sand bedforms, laminated sand sheet, and floodplain fines), which present a fluvial environment. The relation of the architectural elements demonstrates that the Sawahtambang Sandstone uphold a record of the braided river system that flowed from southwest to northeast in the southwestern part of Ombilin Basin. The dominance of coarse-grained (channel and sandy bedform) element over clay-silt grained (laminated sand sheet and floodplain fines) element and the extensive appearance of thick amalgamated channel elements reinforce the interpretation of a low-sinuous braided fluvial system in which the stacking pattern shows the channel bodies accumulated both lateral via lateral accretion of point bar and via vertical amalgamated streams.

Authors: Yoga Kuncaraningrat Edi , Febrina Euginia Gloria , Haqiqie Fauzan Aditya
Published: November 2019

In the last few decades, the utilization of coal to generate electricity was rapidly increasing. Consequently, the production of coal combustion ash (CCA) as a by-product of coal utilization as primary energy sources was increased. The physical and geochemical characteristics of CCA were site-specific which determined by both inherent coal - source quality and combustion condition. This paper provides a state of knowledge review on the effects of CCA application as mitigation to control soil erosion and acid mine drainage (AMD) thus treating water pollution especially in coal mine and near future research needs.
Lithology Effect On Total Organic Content, Maturity Level And Depositional Environment Of Pemaluan Formation as a Shale Gas Bearing Formation, Kutai Basin, East Kalimantan
Authors: Novelyarisyanti N , Iskandar Y
Published: November 2019

Organic material content (TOC) and maturity level is very important in the analysis of shale gas. The organic material is more easily preserved in fine grain sediment such as in shale or clay, so that shale or clay is commonly used to determine TOC value and maturity levels. The organic material will become an oil and gas through the complex transformation and migrated from the source rock to sandstone reservoir, so that the organic material content in sandstone reservoir preferably will represent TOC in shale, however the shale or claystone is commonly used to determine TOC value. This study aims to understand lithology effect on organic material content, maturity level and the depositional environment of sandstone and shale (claystone) of Pemaluan Formation in the Kutai Basin, East Kalimantan. Rock-eval pyrolysis, vitrinite reflectance and GC-GCMS performed on 90 outcrops shale samples and as comparison were one sandstone sample from Rasamala-1 well. Shale samples showed an average TOC value of 1.68 wt% (kerogen type III) and confirmed as a gas bearing formation, while sandstone samples had TOC values of 0.31 wt% which is lower than the shales samples. The maturity level on the shale sample varies from immature to mature, while the sandstone sample is in the mature phase. The organic material from both samples are generated from higher plant material which is strong by terrestrial influence and deposited in transitional environment such as estuarin or fluvio-deltaic setting.

Application of Specific Capacity In Monitoring Groundwater Well : A Case Study of Kota Agung Groundwater Well
Authors: Aryawicaksona S , Muhammad A S
Published: November 2019

Maintaining the quality and quantity of the groundwater from the well is important aspect for the well sustainability. Well monitoring is mandatory for sustainable water management especially for the well with high iron and manganese that easily precipitate at well screen and rock surround well screen due to oxidation. Based on daily well flow rate and water level data, which recorded with electromagnetic flow rate and hydrostatic water level sensor, historically specific capacity data could be obtained. The study case in this paper take place at Kota Agung groundwater well on southern slope of Mount Tanggamus. The well has confined aquifer with lithology sandstone, fractured andesite lava and volcanic breccia as its aquifer and high iron and manganese concentration that enough to precipitate and clog the well screen and rock surround the well screen that impacted well efficiency. Based on historical specific data of the well, well efficiency that impacted by iron and manganese clogging can be predicted without knowing the visual condition of well screen. Decreasing of specific capacity has direct correlation with the well screen clogging and validated by the video logging. By using specific capacity data we don’t need to perform video logging borehole camera to know well condition. In addition to that, by monitoring specific capacity data, well efficiency can be predicted and well maintenance schedule can be defined to restore well to its initial condition.

The use of hormones as one of the therapies is increasingly prevalent at this time, there are many uses obtained by hormone therapy such as preventing miscarriage in pregnant women or as a contraceptive. It was reported that the contraceptive hormone was the most used method by women compared to other contraceptive methods. Diethylstilbestrol (DES) is one of the synthetic estrogen hormones that is useful as hormone replacement therapy. However, the use of DES can also trigger abnormal cell growth that will develop into cervical cancer. This study was conducted to analyze the effect of DES on the p53 gene expression and caspase-3 levels. P53 is a cancer suppressor gene and caspase 3 is a gene that plays a vital role in the process of apoptosis. The method of this study was a post-test design in vivo experiment in animal model which was induced with doses of DES 1500 μgram / BB at 3 days of age after birth, then observed at 35 days. The results showed that there was a significant decrease in p53 gene expression and caspase-3 between DES-induced animals models compared with DES-uninduced with p-value = <0.05. Thus, it was concluded that DES has given to 3-day-old models animals and evaluate at the 35-days-old effect on decreasing p53 gene expression and caspase-3 levels.

In the face of increasingly competitive competition in the hospital industry, RSU managers are required to be able to develop strategies, policies or new breakthroughs related to improving the quality of their services, through improving the characteristics of hospital services, which focus on patient needs, so that the risk of errors or discrepancies between service characteristics that are enhanced by what the patient wants can be avoided or minimized. From the results of research conducted there are 21 variables of patient needs from a health service at the Government General Hospital (RSU). Whereas the patient’s research on the service quality of the Government Hospital is 1 variable that has fulfilled the needs of patients, namely that they are satisfied with the quality of hospital services. Variable is the state and completeness of modern medical facilities. Whereas for other variables there are gaps so that they cannot meet patient expectations until the highest quality limit is very satisfied, it is necessary to have a direction of improvement. To obtain the suitability, the technique used to improve the characteristics of the service is the application of the QFD method. The QFD method in this study is in the form of a quality service matrix at the Government General Hospital. From the HOQ matrix, the service quality of the Government Hospital is obtained from the input of the Government Hospital/management that there are priority variables needed to improve their quality, which is generally the patient’s needs related to the recovery of patients, including the knowledge and abilities of doctors, medicines the treatment given in the healing of patients, the service of examination, treatment and care that is fast and precise, guarantee of security and trust in the services provided and the completeness of the readiness and cleanliness of the equipment used. So there are 33 service quality characteristics prioritized for further improvement, with the main priority being patient recovery.

Published: November 2019

One of the functions of the supply chain system is to provide the right products and services, at the right place, at the right time, and at the desired conditions by still providing optimal contribution to the company. Supply Chain Management is the management of various activities in order to obtain raw materials, followed by transformation activities so that they become products in the process, then become finished products and forwarded to delivery to consumers through the distribution system. The purpose of this study is to improve the welfare of fishermen as fish producers in order to be given equal opportunities in competing to get consumers directly, as well as to provide convenience to consumers who buy fish in accessing information on the location of fish marketing institutions and the selling price of fish. The fish marketing system that has been going on so far have to pass several stages. With such marketing system, consumers do not buy directly from producers. This can be caused by a lack of consumer information on the location and location of fish producers in their environment. By purchasing directly from producers, it can also increase the economy of fishermen as fish producers. Based on this reason, this research creates a model to cut the supply chain of fish sales distribution. The method used is the Supply Chain Operation Reference (SCOR) model and rule based and action Research. The result of this study is the use of the Supply Chain Management model in the One Stop Fish Marketing Information System, which is expected that fishermen will have their own target markets that can directly buy fish from fishermen as the main producers of fish.

The management of beef cattle in Indonesia is still managed individually by farmers. This condition causes low awareness of farmers to manage livestock waste because it is considered not to be of economic value. Managing livestock for production and handling waste is more efficient when using a communal enclosure system. Hence the purpose of this study is to analyse community understanding of sustainable communal cattleshed management. This study generally uses a quantitative approach. The research method used is a mixture (mix method) of quantitative and qualitative methods. The research data were analysed by descriptive statistical analysis procedures and using SPSS 19.0 software. The relationship of community behaviour with an understanding of sustainable communal cattle-shed was tested using the Kendall’s Tau correlation. Based on the results of the analysis of the relationship and the influence and conditions in the field, all variables observed had a significant relationship, had a significant and direct effect on community understanding of communal cattleshed management.

Published: November 2019

We have carried out the experiments on coagulation and precipitation of silica from the separate of Verkhne-Mutnovsky geothermal electric power plant (Mutnovskoe hydrothermal field). Silica precipitation from the water solution was conducted in two ways: by adding slaked lime CaO and by electrocoagulation treatment on aluminium electrodes. Silica precipitation with addition of slaked lime was carried out under laboratory conditions at the temperature of 20 and 96 °C. Colloid and monomeric silica concentrations, solution pH, flakes sizes and physical-chemical properties of material precipitated with different quantities of added lime were determined. We also carried out series of experiments on solution treatment of mixed type: addition lime with freshly precipitated flakes, and addition lime with sea water. In the experiments on electric coagulation, current intensity and distance between electrodes were changed. Dependence of silica concentration on treatment duration was studied. Quantities of electric energy and anode aluminium consumed for reducing of silica concentration to a certain level were obtained. The results of our experiments can be used for developing of technological scheme of silica precipitation and utilization optimal for Verkhne-Mutnovsky geothermal electric power plant.

Published: November 2019

An experimental study to determine optimum operating conditions for mercury recovery from gold mining wastewater has been conducted. Electrochemical characterization of gold mining wastewater was carried out by using steady-state polarization experiment in a batch system. The polarization curves obtained were then utilized to determine the optimum operating conditions. The polarization experiments were conducted by an electrochemical cell with two electrodes of copper (Cu), carbon (C), or stainless steel (SS) and an electrolyte solution of the wastewater. Variations of electrodes used were pairs of copper (Cu), carbon (C) and stainless steel (SS) which were arranged randomly. To obtain the polarization curves, the electrical potentials between 0 V and 3 V were applied and its corresponding currents were recorded at an interval potential of 0.1 V. The highest current density was achieved on electrode pairs of stainless steel-carbon (SS-C) and carbon-carbon (C-C). This is an early indication that the most optimum electrode pairs for mercury recovery possibly are SS-C and C-C. EDX analysis confirmed the presence of mercury in the deposited materials, this leads to a conclusion that mercury can be deposited on to carbon electrode from the wastewater using electrochemical method which then eventually it can be recovered.

Published: November 2019

The directivity pulse motion in near-field earthquake affects the responses of structures. The response includes the roof drifts and interstory drifts, which is so-called the ductility demand. Although many studies have done in this topic, the effect of various post-yield stiffness ratio and ductility capacity ratio to the global ductility demands of reinforced concrete (RC) frames under near-field ground motion is not specifically investigated yet. The trend of global ductility demands of RC frames under near-field earthquake is the objective of this study. The frames are modeled with various fundamental period, behavior factor, plastic rotation capacity, post-yield stiffness ratio, and ductility capacity ratio. The study reveals that the effect of ductility capacity ratio on the global ductility demands is apparent as as the plastic rotation capacity changes. The global ductility demand is also found influenced by global post-yield stiffness ratio and behavior factor.

Responding to the effects of the earthquake and tsunami in 2004, Badan Rehabilitasi dan Rekonstruksi Nanggroe Aceh Darussalam-Nias (BRR NAD-Nias) was assigned as the coordinating and executing agency for improving the region in Aceh province and Nias islands in Indonesia. The allocation for the projects directly implemented by the BRR was approximately USD 2.6 billion. Based on local regulation, these assets must be turned over to the Aceh government. Although most assets were already occupied, neither an appropriate handover nor external project evaluation was conducted. This preliminary study surveyed opinions from building users regarding building quality, the need for building evaluation, and the general opinion for occupying assets with no appropriate handover process in a post-disaster context. The samples included a school, health center, and a sub-district level government office in Banda Aceh city. This study used descriptive methods and a quantitative approach. Results showed the majority of respondents doubted the quality and condition of the assets and agreed with the importance of conducting asset evaluation. However, they are uncertain whether occupying assets before an appropriate handover was appropriate because the post-disaster situation required assets to be functional as soon as possible.
