Abstract
Hepatocellular carcinoma is cancer, which is a significant problem in several countries in the world, one of which is Indonesia. The presence of hepatocellular carcinoma is often accompanied by the occurrence of the metabolic syndrome and infection of the HBV virus. Lipoprotein lipase (LPL) is an enzyme that is thought to be a key factor of metabolic syndrome occurrence and also HBV infection. This computational study aims to see the interaction between ANGPTL8 and HBV virus particles against LPL as a target. Our study shows that HBV and ANGPTL8 have different binding regions in the LPL enzyme so that they can bind simultaneously. Computationally HBV has stronger energy bonds than ANGPTL8. To sum up, this study can be the hallmark of another research to find out the role of LPL to the occurrence of Hepatocellular carcinoma by the binding of ANGPTL8 and HBV.

Abstract
Liver fibrogenesis can turn out into liver cirrhosis and being a fatal failure. Infection of HBV and metabolic syndrome is the major causes of liver fibrogenesis. ANGPTL8 is the hormones that interact with many factors related to HBV infection and metabolic syndrome. The purpose of this study was to crosscheck computational based interaction of ANGPTL8 and TGFβ1 on TGFβR1 as the pathological signal that related to liver fibrogenesis. Our study shows that ANGPTL8 bind better onto TGFβ1R than TGFβ1 so that ANGPTL8 may implicate with fibrogenesis through simultaneous binding into TGFβ1R with TGFβ1. This study work as an initial study that can be used as the basis of the next study to determine the role of ANGPTL8 in the occurrence of liver fibrogenesis due to metabolic syndrome and HBV infection.

Abstract
In this study, water pollution contamination can be eliminated by the AOPs (Advanced Oxidation Processes) method, the photodegradation method that uses photocatalyst techniques made from semiconductor materials such as ZnO which have the advantage of not being easily degraded when light absorption, non-toxic, and environmentally friendly. However, this material is not magnetic so it is difficult for this material to be separated from the solution after being used even though ZnO has the potential to be applied repeatedly. To determine the effect of ZnO concentration on the crystal structure and the magnetization properties of Fe3O4@ZnO Core-Shell Nanoparticles, the fabrication of Fe3O4@ZnO Core-Shell nanoparticles with variations of ZnO concentration had been successfully synthesized by using precipitation method. To investigate the structural, morphological, magnetization properties, and optic properties of Fe3O4@ZnO Core-Shell Nanoparticles, the samples had been characterized by using XRD, TEM, VSM and UV-Vis Spectrophotometers respectively. The results showed that ZnO concentration did not affect the crystal structure. Furthermore, TEM image showed that the core-shell structure was well carried out. The addition of ZnO concentration can affect particle size and can reduce the magnetization properties of Fe3O4 nanoparticles, and can increase the degradation rate of methylene orange dyes.

Abstract
In the last decades, doxorubicin has been widely used for cancer treatment combined with magnetic nanoparticles. Therefore, the development of utilization of magnetic nanoparticles as drug carrier for cancer treatment becomes essential to be done. In this work, we report the preparation of Fe3O4/PEG nanoparticles combined with curcumin as drug delivery agent for doxorubicin. The samples were characterized by means of XRD, FTIR, XRF, and UV-Vis spectrometer. The data analysis of the characterization showed that the spinel crystal structure was detected for both Fe3¬O4/PEG and Fe3-O4/PEG/curcumin. However, the presence of curcumin leaded to decrease its crystallinity and didn-t change significantly the particle size. The functional groups of Fe3¬O4/PEG sample were evaluated at the wavenumber 587.285 cm-1 for Fe-O. The wavenumber of 1108 cm-1 and 2883 cm-1 were originated from C-O-C and C-H. Meanwhile, for the Fe3¬O4/PEG/curcumin sample, despite the functional groups of Fe-O, C-O-C, and C-H, the functional group of -OCH3¬ at the wavelength of 1153.4 cm-1 was detected originated from curcumin. Moreover, based on the drug loading and drug release characterizations for doxorubicin, the Fe3¬O4/PEG and Fe3¬O4/PEG/curcumin exhibited good performance as drug delivery carrier.

Abstract
Mud Volcano is a phenomenon that is often discussed by people. The case of the emergence of mud volcano in Sidoarjo, East Java, or it is better recognized as "LUSI" has attracted the attention to the lots of researchers and the general community. The effects of the destruction of infrastructure and damage to the environment around the emergence of the Mud Volcano are issues that need special attention. The potential for mud volcano has been recorded in lots of locations in Java, both active and interpreted based on rock deposits. One of the areas indicated to be an ancient mud volcano is the Cengklik Lake area of, Boyolali Regency, Central Java, which is the area of this research. The research was conducted using the geomagnetic method. The measurement was conducted around CengklikLake to the east following rock outcrops which are identified as mud volcano deposits. The interpretation is conducted based on the results of data processing that has been corrected daily variation and IGRF. Several filters have been applied to obtain the desired information. The results have shown a low magnetic anomaly value which spread from Cengklik Lake, AdiSumarmo Airport on the west side and spread eastward continuously until around the outcrop which was identified as ancient volcanic deposits. This pattern of low magnetic anomaly values is interpreted as a result of mud volcano deposits in the area.

Abstract
There has not been any certain recognition for the configuration of Kendeng Basin up to recent times. The thick quartered volcanic deposits at the top layer were one of the problems in imaging the configuration of this basin. Geological data interpret that the basement of Kendeng Basin has transitional properties between accretion and continental types. The pattern of a structure due to the collision between microcontinent Australia and Sundaland in this Basin are still questionable. The understanding of the structure pattern is essential due to it will control the formation of the Kendeng Basin. To adds the difficulty, the basement in this basin was not exposed to the surface. Geomagnetic methods were applied to analyze the configuration of the Kendeng Basin. The measurement of Geomagnetic has carried out in the Kendeng Basin in the West and Central Kendeng with the north-south relative line. The distance between measurement points is approximately 5 Km. The pattern of Kendeng Basin can be interpreted with data processing by apply regional-residual magnetic anomalies to obtain deeper anomalies. The structural analysis was carried out on regional Anomaly data by applying several derivative formulas to produce a pattern map of the Kendeng Basin. The results of this study indicate that the basement of the Kendeng basin is a block-faulting with the East-West relative direction. West-East trending structure is the main structure. We interpret the structure to have NE-SW oriented Meratus pattern which formed due to early-Eocene Collision.

Abstract
Edge finite element (vector finite element) which is solved using sparse direct solver (PARDISO) has been used in this paper to model 2-D magnetotelluric field data (Papandayan field data). The site sounding of the field data which is used on this modeling are 10 site soundings. The focus of this paper is on the using 2-D magnetoteluric modeling scheme which is developed to model field data. First, the generating mesh to the field data and choosing the appropriate model are reviewed. Normalize coordinate to get the zero point before the meshing step is important so that the sensitivity matrices did not contain big amount of number which computationally can cause error in calculating matrices. Prior information needed to define the appropriate model. Second, the accuracy of the modeling result (apparent resistivity and phase) is compared to field data. In the end, it has shown that the modeling result has a good agreement with the field data which shows that there are divided by three areas with different resistivity. In the shallow depth (<1500 m) are dominated with low resistivity (around 5 Ωm). Next, the resistivity increases within the depth in 1500m until 3200m which are 150 Ωm until 300 Ωm. Then, finally the resistivity decreased in the deep depth (>3200 m) which around 3 Ωm.

Abstract
Comprehension of hydrothermal flow in geothermal systems is very important in designing geothermal power plant development. As an alternative to qualitative approaches of inferring hydrothermal flow based on geochemistry analyses, a quantitative modeling scheme is discussed in this study. The modeling scheme was carried out by utilizing the Brinkman-s equation as a form of modified Darcy-s law. The equation compensates the effects of buoyancy force exerted on a fluid owing to temperature change known as the Boussinesq buoyancy term. The heat equilibrium equation for a convection-conduction condition was simultaneously incorporated to reconstruct the fluid flow in the associated geothermal system coupled with the temperature distribution in the subsurface. The geometrical constrains of the subsurface geothermal system can be provided from the resistivity structure obtained from the inversion of magnetotelluric (MT) data. Other physical parameters required by the modeling were determined from the results of geological and geochemical studies at the particular geothermal area. The modeling scheme was able to infer numerically the pattern hydrothermal flow pattern as well as its velocity magnitude. The modeling scheme was applied to real geothermal systems in Central Java and East Nusatenggara, Indonesia to test its applicability.

Abstract
The eruption of Sidoarjo hot mudflow (LUSI) has occurred more than 13 (thirteen) years and there are no signs of stopping. Lusi eruption is still active and characterized by geyser activity along with the release of solid and liquid material (Vanderkluysen et al., 2014). Lusi eruption still has the potential to continue to occur in the future, affecting a larger area. Over time, the initial paradigm of LUSI as a mud volcano turned into a volcano phenomenon. Not only mud and hot steam, this eruption also triggers the release of methane gas around the site of the burst. The results of studies that have been carried out have not been able to reveal explicitly the potential occurrence of volcanism at this time (neovulcanism) which emerged in the Kendeng zone in the East Java Basin. Therefore the birth of LUSI as a geyser and some hot water that appears in the kendeng zones becomes a window as well as a new perspective and challenge about the connection of tectonism and volcanism in a sedimentary basin system. Analysis of the geochemical properties of fluid coming out at LUSI and some geochemical hotspring characters that appear in the Kendeng zone in East Java basin can show fingerprints originating from the process of magmatism or not.

Abstract
Background: The incidence of nurse turnover both throughout the world and in Indonesia is quite high. Turnover rates in the world range from 15 to 44%, while in Indonesia the turnover rate ranges from 13 to 35%. Research says one of the causes that can also trigger turnover is a high workload. At X Hospital, the ward nurses workload is quite high, but the turnover rate is low. This makes the researcher want to examine the hospitals efforts in nurse retention, through the nurses working experience. Method: The method chosen in this study was qualitative research with a phenomenological approach. The study was conducted at the X Hospital in February-May 2019. Data collection was carried out by conducting in-depth interviews and unstructured observation. The collected data is then analyzed using the Interpretative Phenomenological Analysis (IPA) method. Results: In the interaction between themes found the core theme is that nurses choose to stay in hospital. The core theme is formed from three themes, namely, nurses prioritize patient interests rather than personal interests, nurses feel united with the hospital and nurses feel working is worship. The three themes were felt by nurses even though the workload was high, not optimal in working and experiencing stressful work situations.

Abstract
Competition in the world of hospital business is increasingly strict requiring hospitals to keep their customers coming and comfortable when going to their hospital. Hospitals must be able to understand customer behavior to find out what they want. Therefore, it is necessary to learn about the customers desires through their experience when getting service. One of the hospitals around Malang has decreased the number of outpatient visits from year to year. Hospitals that focus on geriatric services are hospitals that have not partnered with BPJS. Seeing this phenomenon, this study aims to reveal the meaning of patient experience when getting outpatient services at this hospital. This study took data by conducting in-depth interviews with 5 patients who visited the hospital. The method used is a qualitative research design with a phenomenological interpretation approach. Data was then analyzed using Interpretive Phenomenology Analysis (IPA). From the results of the analysis, it was found that the pleasant experience obtained by patients while getting services at the hospital can encourage patients decisions in choosing a hospital. Hospitality and speed of service provided by all hospital staff make patients happy and want to visit again. This shows the need for an experiential marketing in hospitals to be able to retain loyal customers and attract new customers.

Abstract
ABSTRACT BACKGROUND Over the past 40 years there have been significant changes in the disease pattern around the world. Non-communicable diseases (NCDs) have replaced the earlier global threats to health such as undernourishment, malaria, HIV and TB. The major NCDs responsible for these deaths included cardiovascular diseases (17.9 million deaths); cancers (9 million deaths); chronic respiratory diseases (3.8 million deaths); and diabetes (1.6 million deaths). In Indonesia, 35% Cardiovascular diseases, 12% Cancers, 6% Chronic respiratory diseases, 6% Diabetes, 15% Other NCDs, 21% Communicable, maternal, perinatal and nutritional conditions, 6% Injuries. The global probability of dying from one of the four main NCDs in 2016 was 18%, with a slightly higher risk for males (22%) than for females (15%). The significance of gender equity and gender inequities for women-s health has been recognized internationally. Women are affected by NCDs in different ways to men. Not only are women-s experiences of NCDs influenced by the social conditions of women-s lives which are different to those of men, NCDs often manifest differently in women than they do in men. Moreover, women experience a higher burden from chronic disease and live more years of life with a disability from chronic disease then do men. In this study, we analyze the most common cause NCDs related to woman in outpatients internal medicine clinic patients at I Lagaligo Hospital, East Luwu, South Sulawesi. METHOD This study was held in February – June 2019. We collected all the new patients in outpatient internal medicine clinic. This study was a cross sectional study with descriptive analysis. RESULT In five months, we found 319 subjects with newly diagnosed as NCDs. 179 were women (56,1%). From these two groups, we found CVD as the highest NCDs (93 cases in women and 40 cases in men). If we focused on the women group, based on age, in 15-29 and 30-49 years old, thyroid disease as the highest NCDs. In 50-59, 60-69, and more than 70 years old, CVD as the highest. CONCLUSION The most common newly diagnose with NCDs in woman is differed based on age stage, in the younger age group, dominated with thyroid disease, meanwhile in the older group, CVD as the most of NCD.
