Abstract
This paper unveils the Philanthropic perspective of Khanqahs and shrines of Sufi Saints entrenched in Islamic Ideology. These have always served as significant training centers and substantially contributed towards the religious, social and spiritual upbringing of humanity at large. Furthermore, these institutions have staged a significant role in relieving the sufferings and grappling with social and economic issues especially of the lower rung of society. The founders of these Khanqahs were great Islamic figures who set aside their entire span of life for Philanthropic ends to promote peace and sublime moral values and thus to rid the society of religious, political and economic ills corroding humanistic bounds. After the decease of these sacred figures, their shrines became great Socio-Religious institutions and hence took the form of Philanthropic organizations meant for the welfare of needy and poverty – stricken humanity. These institutions are striving to their utmost in various directions. They have set up schools, free lodges, established health centers, hospitals, orphan care homes and places where hungry and needy could feed them self for free etc. The present study explores the concept of Philanthropy underlying the injunctions of Islam. The research has been delimited to five major shrines in Pakistan for data collection. A detailed questionnaire was filled up by the target research population. It followed a mixed paradigm, qualitative as well as quantitative. The study will not only dilate on the positive aspects but also on the lacunas in the role model of Khanqahs and shrines as, institutions in Pakistan.

Abstract
Geothermal is a potential renewable energy source to be developed in Indonesia. Indonesias geothermal energy potential is recorded at 28,579 MW, but has only been utilized for electricity generation of around 1,948.5 MW. Investment in geothermal power plants is an investment that is capital intensive with high investment risk factors. This study aims to determine the financial feasibility of investing in geothermal power plants in the Gedongsongo geothermal field with 55 MWe of potential electrical energy. In addition, research is conducted to find out from the beginning of the project implementation to the end of the projects economic life and to determine the feasibility level of financial feasibility of investment in the project. The results of investment analysis use sensitivity analysis, indicating that price movements in project calculations have a large influence on changes in NPV. Sensitivity analysis is carried out on several parameters that affect the project value (in the form of NPV) with a Low Case of 70% parameter value and High Case of 130%. The inflation rate for operating costs such as O & M, Make Up Well Drilling and Overhaul is assumed to be 2% per year. Project financing is assumed to originate from personal capital of 30% and loans of 70% with interest rates (interest) of 4% per year. To get the value of the internal rate of return on personal capital or the Equity Internal Rate of Return in accordance with PLN standards of 14%, the electricity tariff for the Gedongsongo Geothermal power plant is USD 11.45 cent / kWh.

Abstract
After the 2010 eruption, the government declared that building settlement inside an area that directly affected by hot cloud should be avoided. Activities within Disaster Prone Area should be limited as the government declared. To accommodate the community, government through rehabilitation and reconstruction program provided house aid. It was a real settlement concept with a public facility. In a new place, a new strategy and way to keep living were needed. With their assets after the eruption, the community adapted to manage and utilize resources. This research aimed to assess perception change within the community on the character change of Mt. Merapi eruption and adaptation strategy to build community resiliency and their economic assets. This research utilized Participatory Rural Appraisal (PRA) in a participative way. Interview, focus group discussions were utilized as instruments, and supported by tendency and change, daily routine, mobility map, and plantation sketch. The result of this research used qualitative-descriptive analysis. Research showed that the character change of Mt. Merapi eruption enriched Batur residents- experience and knowledge. Therefore, they became more resilient in facing future eruption. Their resilience can be seen from their ability to manage their living assets. Adaptation within a new environment can be made through utilizing existed assets and managing it. Compared to the residents of Batur assets before the 2010 eruption, their assets tend to increase.

Abstract
Surface Related Multiple Elimination (SRME) technique is known to have ineffectiveness to attenuate shallow water multiples, primarily because the water-bottom reflection required by SRME for predicting the multiples is not recorded due to lack of near offset data. The conventional technique using predictive deconvolution in either x-t or tau-p domain is often used to suppress these multiples, however, it also attenuates primary events that have a periodicity close to that of water layer. These limitations cause unrealistic seismic images in final output. In this paper, we propose an enhanced technique by modelling the water-bottom reflection and then adding it to the recorded seismic data. The modified data can then be used to predict first order multiple. We present multi stages processing workflow for removing water-bottom multiples in shallow water situations. Firstly, we use a multi-channel prediction filter estimated from the multiples for attenuating short-period water-layer related multiples. Secondly, we apply F-K filter for isolating signals from noise in frequency-wavenumber (f-k) domain. Lastly, SRME technique for suppressing other long-period surface multiples generated by sub-surfaces underneath the water-bottom. Through real-data examples from Nias Waters, North Sumatra, we demonstrate that our workflow provides an optimal multiple attenuation solution in shallow water environment in comparison with conventional methods such as predictive deconvolution or SRME alone. Tests result show that the multi stages technique can produce better result than using predictive deconvolution or SRME alone. Furthermore, we also show SRME approach can give optimum seismic migration images after we combined these stages. We successfully applied these techniques in 2D seismic data of Nias Waters.

Abstract
The stability of tunneling in the underground mine is an important factor in the production of mines that must ensure productivity and safety. In Antam Underground Gold Mine, the production cycle starts by drilling the tunnel then charge the explosive material. After that, the tunnel is blasted before the ore mucking activity. The activity continues to reinforcing the tunnel and back again to the beginning of the cycle, drilling activity. The drilling is using Jumbo Drill which has 3-meter drilling rod. With span progress is about 2.7 from 3 meters or 90% of the drilling rod length, in a tunnel with dimension 5-meter-high and 5-meter-wide, the mining is producing 170 tons in 8 hours which can be considered the productivity 21.25 ton per hour each Jumbo Drill. Among many rock conditions affecting stability, the width and height of tunnel are an important design factor. In this paper, the aim is to optimizing blasting activity by considering the maximum unsupported span (MUS) using the Q system. The mining factor like the equipment size, geological condition and productivity cycle are combined and considered to get the optimum span value in a variety of rock mass at Antam Underground Gold Mine. The output of the research is the maximum unsupported span value has a variety figure from 1.8 to 8 meters depending on the rock mass characteristic. By observing the mining operation factor, the maximum span can be proposed in 4.2-meter length. Although the drilling time getting longer 20%, the production tonnage increase 40% which mean productivity also climb 20%. As a result, by utilize MUS and considering the mining factor, the productivity can be enhanced and safety guaranteed.

Abstract
The hydrogeological system of Menoreh Hills, Purworejo Regency area is generally built by fissure aquifers consisting of volcanic pyroclastic breccia, lava, intrusion, and laharic breccia intensively jointed. On the other hand, there are also semi karstic and intergranular aquifer systems compiled by carbonate clastic sedimentary rocks of the Sentolo Formation. Hydrogeologically, the presence of groundwater is inserted in rock crevices (fissure aquifers), and occupying either cavities or inter-granular pores (semi karstic - intergranular aquifer). In general, the value of groundwater pressure is relatively high, proven from the fact that the hydraulic head in volcanic fissure aquifer ranges 150 m – 400 m, while in carbonate aquifer is about 110 m – 150 m above sea level. Groundwater pressure is one of the triggerring factors for landslides. Influenced by hilly topography with moderate to steep slope inclination of 4o – 35o (13% - 70%), thick soil (2m - 5m), high rainfall (>2000mm/year), and saturated soil (water content = 13% – 39%), the Menoreh Hills represents a high potential for landslides. The potential grades can be grouped into low, medium, and high categories. Based on hydrogeological studies, there is a correlation between the hydrogeological system represented by the types of aquifer with the potential of landslides. Volcanic fissure aquifer type indicates higher landslide potential than the carbonate intergranular aquifer type.

Abstract
The main workable coal measures are concentrated at two horizons within the Miocene Muara Enim Formations (MEF). The main Coal Bed Methane (CBM) targets are the MEF coals, which are known to have good coal thickness and favorable depth for CBM production. Typically, coals are recognized to thin toward the east as they pinch out against the Sunda landmass. Important elements of the CBM play are coal presence and coal lateral distribution. The objective of this study is to identify thin coal reservoir distribution by using well and seismic data integration. Reprocessing seismic data prior to acoustic impedance (AI) inversion produces better results. In situations where wells are located far from seismic lines, calibration with logs is problematic and inversion produces less than maximum results. Multi-attribute approach can optimize the results. Integration of the filtering, AI inversion, and then multi-attribute & neural network methods produce the best output to identify coal seams, their distribution and continuity. The thickest coal identified well data (10 wells) of 6 m in depth 768 m with a total of 5 layers of coal (seam A, B, C, D, and E) in R5 well. Based on seismic modeling, the seams was only seams A with a total volume respectively 518 million m3.

Abstract
Tuk sibedug is a spring located in Seyegan sub-district, Sleman Regency. This spring is never dry even in the long dry season. Myth says that the spring is purified because it was discovered by Sunan Kalijaga during the Islamic dispatch in Java. This study aims to determine the subsurface conditions around Tuk Sibedug and determine the configuration of groundwater systems in these areas. The study was conducted by measuring the geoelectric method of Dipole-dipole configuration. Measurements were made on 3 tracks around the spring with a target depth of about 90 m. The tool used is Syscal Jr Switch-48. The software used is Global Mapper13, Surfer10, Res2dinv3, and Arcgis 10.3. The result interpreted as clay stone, sandstone, and breccia. The clay has the smallest resistivity value ie (3.80 - 9,18) Ohm-meter, sandstone (9,18 - 34,40) Ohm-meter, and breccia (34,40 - 83,10) Ohm-meter. Ground water is stored in sandstone. The type of aquifer is a confined aquifer so it has it own natural pressure to push the water to the surface.

Abstract
Karawang Regency in Regional Regulation (Perda) No.2 of 2013 concerning Regional Spatial Planning (RTRW) 2011-2031 in Article 54 mandates the development of industrial strategic areas in Telukjambe (Kec. Telukjambe Barat, Timur and Ciampel). Karawang in January 2014 experienced flooding at several points resulting from the overflow of the Cibeet River and the Citarum River. Distribution of this flood occurred in the district Telukjambe West, East, Ciampel, Karawang West and East. Underground river systems and cave networks in the Jatiluhur Formation have the potential to reduce the discharge load from existing surface rivers. Cave systems and underground rivers in the Kuta Tandingan Hills can reduce surface runoff by up to 80%. The porosity of the Kuta Tandingan Hills can reduce surface flow by 21%. The peak load of the Citalahab River occurs at the beginning of the river where the channel is narrow, but the additional load from the surface flow is so large.

Kaltim Prima Coal 2Mining Statistician, Technical Section, Hatari Dept, PT. Kaltim Prima Coal Perkembangan dan persaingan industri pertambangan dunia semakin ketat, sehingga perusahaan pertambangan dituntut lebih kompetitif dan menerapkan praktek operasional tambang yang efektif, efisien, dan produktif tanpa mengesampingkan aspek safety. Unit Liebherr R9800B adalah salah satu alat gali muat terbesar di dunia dioperasikan oleh PT. Kaltim Prima Coal. PT. Kaltim Prima Coal mengoperasikan 3 unit Liebherr R9800B, 2 unit di Bintang Department (S601 dan S602) dan 1 unit (S603) di Hatari Department. Pengoperasian Liebherr R9800B mempunyai tuntutan dan ekspektasi produksi yang tinggi, sehingga peningkatan overburden yang dipindahkan selaras dengan batubara yang terbuka. Beberapa improvement dilakukan untuk meningkatkan produksi R9800B, mulai dari metode sistem pemuatan, kombinasi truck yang digunakan, metode penggalian, memaksimalkan waktu operasi digger (pembuatan access refueling, access pergantian operator), dll. Area operasional Hatari Department berada di sisi utara area PKP2B PT. Kaltim Prima Coal. Karakteristik area utara memiliki nilai UCS batuan rendah 1.71-2.37 Mpa dan kerapatan interburden batubara lebih rapat dibanding area selatan. Hal ini menjadi tantangan tersendiri jika mengoperasikan Liebherr R9800B dengan berat 800 ton dikombinasikan dengan truck Euclid EH5000 500 ton. Berdasarkan plan 2019, usage R9800B ditargetkan sebesar 60.02%, dengan productivity 3,069 bcm/hour, dan produksi 37,932.49 bcm/day. S603 berpindah dari area operasional Bintang Department ke area operasional Hatari Department pada pertengahan tahun 2017. Saat beroperasi di area Bintang department, S603 mencatatkan rata-rata produksi 54,012.49 bcm/day dengan pencapaian produksi maksimal sebesar 29,120.83 bcm/shift dalam periode 2 (dua) tahun. Kemudian saat berpindah area kerja Hatari Department, tercatat rata-rata produksi sebesar 62,229.15 bcm/day dengan produksi maksimal 33,108.32 bcm/shift dalam kurun waktu yang sama. Dengan karakteristik area operasional yang berbeda jauh dibandingkan area Bintang, S603 mampu berproduksi lebih baik saat beroperasi di area Hatari. Tetapi hasil produksi antar crew section operation Hatari Department di tahun 2018 menunjukkan variance yang terlalu tinggi, produksi didominasi oleh satu crew. Crew Alpha memimpin perolehan produksi R9800B, crew Bravo mampu bersaing, sedangkan crew Charlie tertinggal jauh. Berdasarkan review performance tahun 2018, maka operation dan technical section berkerja sama melakukan analisis terhadap performance R9800B mulai awal tahun 2019.

Abstract
Gas lift has been successfully operated in many types of oil wells around the world. Many techniques have been derived to increase gas lift efficiency, not only from gas lift modeling but also technical designs of gas lift components have been tweaked to produce higher gas lift performance with less gas injected. Gas Lift Performance Curve currently holds as one of the most prominent evaluation method of gas lift performance. The method itself is derived as a subcomponent of Inflow Performance Relationship (IPR) curves that allows simple and robust GLP curve generation without having to perform procedural, iterative calculations. It is worth noting, however, that GLP curves cannot be held as a single culmination parameter in determining the efficiency of gas lift systems. This study introduces a new paradigm in modeling the performance of gas lifted wells by utilization of mechanistic fluid flow modeling. Mechanistic models, unlike conventional GLP curves, are generated from observations in full scale laboratory experiments, therefore complications in multiphase flow pattern, such as flow pattern transition can be fully acknowledged and incorporated into the calculations. Based on the previously stated hypothesis, this study offers a case study on marginal oil well where gas lift acts as the main extraction method. Observations done in the model has confirmed the functionality of Flow Pattern Map (FPM) derived from mechanistic modeling as a complementary check and balance tool for gas lift systems. It is also expected that the FPM will perform well in a multitude of gas lift case studies due to its versatility.

Abstract
Drilling fluid (mud) is an important factor in drilling. Geothermal reservoirs are often found in local and regional faults which result in large permeability so that it often results in lost circulation during the drilling process. To prevent this, the hydrostatic pressure of the drilling fluid must be as small as possible compared to the formation pressure by adding additives. Addition of natural ingredients as additives has advantages compared to chemicals which are affordable, easily available and abundant and environmentally friendly. The research method uses laboratory studies with basic ingredients of water and bentonite and the addition of natural ingredients additives. The independent variable of banana midribs is 5 grams and 10 grams at temperatures of 80 0F, 150 0F and 300 0F. The dependent variables are density, viscosity, plastic viscosity, gel strength, yield point, mud cake and filtration loss. The results showed that the best natural additives to resolve lost circulation.

Abstract
Mining industries face uncertainties over time, including in the gold mining. The uncertainty in the gold mining project is most likely due to the financial risk (i.e., prices). The gold price fluctuation in the industry may shape the industry characteristic, either risky or not. Moreover, the gold prices are hard to predict, decision makers are suggested to quantify the project risk in advance. In this paper, the risk is quantified by correlation analysis, Copula method. Copula is a powerful tool to describe not only linear, but also non-linear correlation between random variables. In addition, the Monte-Carlo simulation – a popular and standard approach to assess the risk – is incorporated in the Copula. This approach is straightforward, fast, and applicable for different project or country. A case study is performed to make the approach more clear.

Abstract
Increasing and expanding the function of land use due to human activities can lead to potential pollution of groundwater. As a method that has been tested and has a precise scoring system, this study tries to use and compare the SINTACS and DRASTIC Methods to conduct groundwater vulnerability assessments (GVA). This study aims to create and compare the models of intrinsic and specific GVA from the SINTACS and DRASTIC methods and find out the most reliable model to be applied to the Karangkobar Groundwater Basin. Intrinsic GVA is carried out with the SINTACS and DRASTIC methods using seven parameters that are almost the same but differ in detail of classification, weight, and rating. The specific GVA is carried out with the Nitrate Vulnerability Index (Modified-DRASTIC) and SINTACS Specific Vulnerability Index (Modified-SINTACS) which uses additional parameters in the form of Anthropogenic Impact (AI) and Potential Risk Associated with Land Use (LU). These additional parameters are representations of land conditions that are affected by nitrate pollutants (NO3-). All models were validated using the nitrate concentration within 34 observation points to determine the level of models suitability with nitrate groundwater pollution conditions in the study area. The four GVA models show almost the same results. In general, areas with a High-Very High vulnerability are found in agricultural areas composed of pyroclastic sediment aquifers, while Low-Intermediate vulnerability levels are found in protected forest areas composed of alluvium deposits and pyroclastic deposits aquifer. Statistical analysis shows that the GVA models which have the strongest correlation (r = 0,8) with nitrate is the Nitrate Vulnerability Index model, so this model is considered the most appropriate to be applied in the study area.

Abstract
In this study a prototype of a Hybrid Power Plant (PLTH) will be built that integrates the Pico-hydro Power Plant (PLTPH) and the Solar Power Plant (PLTS). The prototype of the PLTH to be built has a capacity of 500-1000 watts. From the making of the prototype-1 it was discovered that the PLTPH produced a maximum power of 86 W (from a capacity of 100 W) and the PLTS produced a maximum power of 30 W during bright weather and 23 W when the weather was dim (from a capacity of 100 W). The results of testing on prototype-2, it is known that PLTPH with a capacity of 600 W produces maximum power of 257.48 W and PLTS with 3 x 200 Wp (watt-peak) solar panels producing maximum power of 176.4 watts. After some adjustments, the electrical energy from these two sources is then stored in the battery. Electrical energy from PLTS is stored on the battery after going through the MPPT Solar Charge Controller; while the electrical energy from the PLTPH is stored on the battery after the electricity voltage is lowered and rectified with the rectifier. From the results of observations and measurements during testing, these two sources of electrical energy can charge the battery normally. Electrical energy from batteries that are direct current electricity is then converted into electrical energy alternating current of the power frequency to be supplied to the load, especially the electric load of alternating current.

Abstract
ASBTRACT This research is based on the reality that the focus of sustainable development has not been too large involving village community participation. Programs carried out in villages are generally determined from above. Independence is not formed and the village is increasingly dependent on the program from above. This research wants to see and understand the ability of the village to develop itself into an independent village by utilizing all the potential that exists, knowing and understanding the process of meaningful community environment that is able to move the economic, environmental, and social dimensions for self-independence. Using qualitative methods with a case study approach, this research shows that the development of village independence is very dependent on the visionary figure of the village head, the ability to see and capture opportunities and build networks. Village independence always considers economic, environmental and social aspects. These three elements are interwoven through environmentally friendly communication patterns.

Abstract
Cattle production in Banten Province is usually done alongside paddy cultivation. To gain optimum results, paddy cattle integrated systems was implemented in Sabana Mandiri Farmers Group in Rajeg Sub-district, Tangerang District of Banten Province. Since the cattle production is still carried out traditionally, the implementation of paddy cattle integrated systems needs strong institutions. The objectives of the present study were to describe methods to build strong institutions in paddy cattle integrated systems and analyze the impact for the farmers. Institutional strengthening was carried out through various methods including facilities and infrastructure assistance, improvement of cattle production systems, farmer training, and the establishment of farmer institutions. Facilities and infrastructure were provided in the form of cattle, communal cages, digester and feed warehouse. The improvement of cattle production was carried out from the shifting of an individual and a traditional cattle production into a communal and an intensive cattle production. Training was conducted to enhance farmers skill and knowledge about cattle production systems, such as feeding, cattle rearing, and by-products management. The intensive cattle production was able to increase cattle weight by an average of 143 g/ head/day or equal to 25% weight gain compared to the traditional cattle production.

Abstract
Evacuation strategy is one of important stages in disaster management, particularly in the case of the 2010 erupsion of Mount Merapi, Yogyakarta, Indonesia. Rather than just evacuating people, the case shows that Indonesias government had to manage peoples livestock wisely without taking risks of increasing victims of human. Several incidents of natural disaster have improved Indonesias experiences in dealing with disaster management. Various approaches ---behavioural and structural ones--- have been applied in various natural disasters. However, those approaches cannot easily be imposed in the evacuation strategy at the Mount Merapi. This paper analyses the use of socio-cultural approach in handling evacuation problems at the 2010 erupsion of the Mount Merapi. This third approach is of importance for dealing with unique local condition of people lived arround Mount Merapi. Socio-cultural approach aims at helping disasters stakeholders successfully managed problems of evacuation. Although people were managed to be evacuated to secured areas, they frequently returned to their home in disaster areas. Learning from their daily life and local culture helps successful evacuation in the Mount Merapi by bringing people and their livestock out of disaster areas. This approach helps disaster stakeholders to learn about local wisdom of people who lived in sorrounding areas of Mount Merapi. Another lesson is that this evacuation strategy enabled disaster-affected people kept looking after and securing their livestock, while they lived in secured areas. Therefore, developing socio-cultural approach in the evacuation strategy of the Mount Merapi also helps complement ---rather than substitute--- other useful approaches which were formerly applied in other disaster areas for disaster management.

Abstract
The population growth rate and economic growth that increase every year results in increased energy needs that are used to support human activities in daily life. Energy consumption in Indonesia comes from petroleum, coal, natural gas, renewable energy (EBT), and hydropower. Petroleum has the largest portion of energy consumption in Indonesia where upstream oil and gas activities, namely exploration and exploitation carried out to meet energy needs, have not been able to meet domestic energy needs. On the other hand, the decline in the economic level of the upstream oil and gas industry due to changes in world crude oil prices has resulted in reduced investment in this industry. By looking at the condition of non-renewable petroleum natural resources, the tendency for oil and gas needs to continue to increase, while the availability and oil and gas reserves are always decreasing, this has an impact on the upstream oil and gas industry in Indonesia. Looking at it from the standpoint of Sustainability Theory, where meeting current needs without sacrificing the needs of future generations can be applied to the upstream oil and gas industry. Using the Artificial Neural Network method to create a model that can see the behavior of the carrying capacity of oil and gas exploration and exploitation activities in Indonesia which consists of petroleum reserves, the rate of petroleum production, and investments that can be used as a policy-making instrument to support sustainable development goals in the upstream oil and gas industry in Indonesia.

Abstract
The presence of personnel in units, especially in carrying out basic tasks, is in the military. Absence without permission, or called desertion, is considered illegal, which is one of the crimes regulated by law. Esprit de corps is the unit spirit which functions as a member of the unit. Esprit de corps was built since the recruitment process. Leadership plays an important role in maintaining esprit de coprs unit strength. The units adherence to its members is expected to be able to suppress the intention of deserting unit members. This quantitative study aims to empirically determine what factors directly influence member desertion intentions. By using the Structural Equation Modeling (SEM) estimation technique on 300 respondents who are Navy soldiers, the results show that esprit de corps is the most significant variable to reduce desertion intentions. Indicators of more unit values provide the most powerful influence in explaining esprit de corps. Leadership is also like that but not as strong as esprit de corps. Whats interesting is the influence of leadership is very strong against esprit de corps. Attention to members through direct communication is a very strong indicator of leadership in increasing unit esprit de corps.
