Authors: Damaiyani Janis , Prabowo Heri 
Published: November 2019

Abstract
Rosewood (Dalbergia latifolia Roxb) is a vulnerable species with quality and commercial timbers. Hence, a conservation is necessary to prevent rosewood from extinction in the near future. Information on insect pollinators is fundamental for initiating the rosewood conservation in wildlife. Insect pollinators are highly beneficial to bring fertilization. This research aims to identify the insect pollinators on rosewood plants. The research was implemented in Purwodadi Botanic Garden used Completely Randomized Design (CRD) with three replication. This research conducted when the flowers bloomed in September 2018 starting from 07.00 – 11.00 am. The insect abundance was calculated via a scoring method. The observation showed 5 types of the visiting insect pollinators in the rosewood collection of the Purwodadi Botanic Garden. Such five types of insects include Xylocarpa confusa, X. fenestrate, X. iridipennis, Apis cerrana, and Polistes metricus In term of the level of abundance, there are two species of pollinators found, namely X. confusa and A. cerana. Among the two, X. confusa is the most dominating species of pollinators on rosewood of around 25 bees. In accordance with the results of the research, it is necessary to develop a conservation strategy of X. confusa for rosewood in wildlife. One method of conserving the pollinator is by establishing a habitat to support the pollinators’ lives. The existence of X. confusa and A. cerana can preserve rosewood plants and save them from extinction.

Abstract
The western part of Java is adjacent to the intersection of major tectonic plates between Eurasia and Indo-Australia. This region is often stricken by natural disasters due to its tectonic and geological setting, such as earthquakes, tsunamis, volcanic eruptions, floods, and landslides. West Java Province with more than 40 million inhabitants is the most populous region in Indonesia, where Sukabumi Regency in the southwestern part of this province is known for the frequent location of earthquake. In the southwestern part of Sukabumi Regency, the Ciletuh-Pelabuhan Ratu Geopark has been recognized as one of the newest UNESCO Global Geopark. This study concerns about assignment of Geopark area, which will increase the visit of tourists despite its vulnerable condition to earthquake event. Schools as part of education sector in the study area are functioned as central location for people-based education as well as shelter when disaster happens. This paper is aimed to reveal the perception of earthquake hazard and knowledge among school community as disaster stakeholders. This study is carried out on schools near the vulnerable areas to earthquake events. Several schools had been visited and examined the curriculum, disaster preparedness for earthquake, and mitigation activities. The earthquake brochures and GIS-based vulnerability maps were distributed to students and school’s library. Discussion about the maps with the teachers and students are conducted to examine the understanding of contents as well as to obtain their perception about earthquake. Results showed that earthquake vulnerability map increased the knowledge and gained positive perception on how to respond during earthquake event because initially most of participants were unaware what to do when earthquake happen. This result suggests that dissemination and improvement on perception to respond the earthquake are deeply needed. The school community as disaster stakeholder can play an important role on community-based disaster risk mitigation.

Abstract
Prospective area of Solok geothermal lies in step over transtensional between two segments, Suliti and Siulak, Sumatra faults. Geological structure in this prospect area shows structural pattern controlled by “oblique divergent strike-slip fault system” (releasing bend) as a proceed of embraced movement from Sumatra fault and establishes “dilation zone” between those two segments, forming negative flower structure in direction of NW-SE and N-S. The pattern of geological structure is predicted to control the availability of solok geothermal system which in this case related to presence of surface manifestation. The pattern of geological structure is predicted to control the availability of solok geothermal system which in this case related to presence of surface manifestation. Surface manifestation indicates good permeability zone that can be used as flow path of geothermal fluid from reservoir.

Abstract
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

Abstract
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

Abstract
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

Abstract
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

Abstract
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

Abstract
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.
