Abstract
Marriage has a significant meaning for human life. It is one of the forms of developmental task fulfillment in early adulthood closely related to partner selection and also as an individual medium to meet individuals spiritual, social and sexual dimensions. Marriage broadly covers relationship which involves husband and wife as to establish a family and as a means of sharing emotional and physical closeness as well as various roles in the family. A married couple usually encounters problems in living married life. Dynamics in a married life are affected by various things which come either from the couple or from the couples family. The dynamics sometimes induce some problems in the marriage, which cause such various impacts on married life as anxiety and individual-s quality of life that may lead to a divorce. The objective of this research us to investigate how individuals go through divorce cases that they experience and their impact on their health. This research used the qualitative research method. Snowball ball sampling was used to determine its samples. They included five divorced persons. The result of the research shows that a process to go through an adversity due to a divorce is a prolonged process and bears an uncertain of success. The divorce impacts on individual-s life after divorce, both of his or her physical health and mental health. Mental and physical health disorders are commonly experienced by some individuals shortly after divorce. Yet, some cannot rise from adversity so that they still experience mental and physical disorders.

Abstract
Land Productivity can be affected by physical and human factors. Physical factors that can affect the land productivity are temperature, number of wet months, drainage, texture, pH, soil depth, slope and others. Landform defferences can cause a differences of physical factors betwen one and another land. The differences of physical factors caused a differences in paddy varieties, type of fertilizer and community paddy planting method. Paddy varieties, type of fertilizer and community paddy planting method are human factors that can affect land production. Ponjong, Semanu and Karangmojo district are districts in Gunungkidul Regency that have the largest paddy field area. Most area in that districts is included of Gunung Sewu karst area and the others area is non – karst area. This research want to know the spatial pattern comparison of Paddy field Productivity on Karst and Non – Karst Area. Temperature, number of wet months, drainage, texture, pH, soil depth, cation capacity, base saturation and slope, paddy field productivity was used as the variables in this research. In this reasearch matching method was used to get the paddy field suitability class, afterwards nearest neighbor analysis and spatial analysis was used to get the spatial pattern of paddy field productivity. The result show that average productivity on non – karst area is higher than karst area. In the karst area, most of high class is located in Karst Plateau landform. In conical karst landform, slope is the main inhibiting factor for land productivity. In Karst Plateau is pH and drainage, whilst in non – karst area inhibited by rooting.

Abstract
An earthquake is a natural disaster that is often found in Indonesia because its geological area is a meeting between three large tectonic plates. Earthquakes have a high level of danger due to unpredictable events. In the Sulawesi region, especially Makassar, in 2017 there was an earthquake measuring 3 SR-6 SR, with a shallow epicenter. Epicenter distance calculation is used to determine the value of peak ground acceleration (PGA) which can then affect the intensity value in the hypocenter. This study aims to analyze the level of earthquake hazard using the PGA value as the basis for the initial reference of earthquake disaster mitigation. Variables used include rock type (geology), slope and the value of peak ground acceleration (PGA). Data on rock types were obtained from the Makassar City BPBD and slope variables were processed from the SRTM DEM. Next, an overlay analysis was conducted to determine the level of earthquake hazard using a GIS application. The results showed that Makassar City had a majority of 94% of its area has a low level of earthquake hazard while 6% of the area that had an earthquake hazard level was quite high in the east of Makassar. The frequency of earthquakes that were felt to be influential by the community (scale III MMI) was only 2 times in the last 3 decades (1996 and 2018).

Abstract
Introduction: Diabetes is caused one them by inflammatory regulation disorders. Metformin has been reported that inhibits the physiological function of normal cells. Asiatic acid, a bioactive compound from centella asiatica has the potential to be developed as a therapeutic agent for diabetes, but little is known about its toxic effects on macrophage cells and fibroblast cells. Objective:The aims of study is evaluate the toxic effects of asiatic acid and metformin on the viability of RAW264.7 macrophage cells and NIH3T3 fibroblast cells. Method: Asiatic acid and metformin with seven concentrations were given to RAW264.7 macropage cell lines and NIH3T3 fibroblast cell lines. Viability percentage is calculated using the 3- (4,5-dimethyltiazol-2-il) -2,5-diphenyltrazolium bromide method and the absorbance is measured at 595nm. Results: Results have shown that asiatic acid with concentrations> 12.5 μg / mL decreases the viability of RAW264.7 and NIH3T3 cells drastically. RAW264.7 and NIH3T3 cells that had been given metformin concentrations of 11.6 μg / mL to 370 μg / mL still showed a large percentage of cell viability. Conclusion: Asiatic acid has shown that the cytotoxic effect is greater than metformin, so it is necessary to pay attention to the concentration of the treatment.

Abstract
The alternative sweetener used to beverage and food with a calorie controlled, to control weight loss program or to prevent tooth decay. The alternative processes that are currently being developed are producing of xylitol from xylan of the cellulose biomass. The goal of this study is to determine the most influential process variable and optimum operating condition of xylitol production through enzymatic hydrolysis reaction of corn cob waste. The parameters are the time (30-120 minutes substrate ratio:starter (1:5-1:15 w/w). The result showed a high number of cell on a substrate concentration of 10% led to increase in xylose consumption while the xylitol production is not too large because the substrate is used for yeast cell growth so that production of xylitol to be reduced and the efficiency is low. The high efficiency (25%) occurred in 20% of substrate concentration because the xylose consumption is used for growth and xylitol production. While the concentration of 30% decline in the consumption of xylose by yeast compared with others and the efficiency is not too high. This is because the high concentration of xylose which led to substances inhibitor in the media and the production of xylitol become low.

Abstract
A refrigeration system that uses Ammonia Anhydrous in the liquid phase and the gas phase. The refrigeration system has the potential for gas leakage which poses a risk to worker safety as well as environmental pollution to water bodies and air pollution. This risk might have an impact on employees in the factory area and could extend to the surrounding community. This study is intended to be able to analyze the risk of pollution accurately before installing the refrigeration installation. In this study the analysis method that will be used is the statistical method and the use of mathematical models supported by Aloha software. The distribution of pollutants from ammonia gas leakage is influenced by several factors, including the capacity of the refrigeration system, meteorological conditions, and land use. The use of Aloha software in the prediction of zones affected by the spread of toxic substances in the atmosphere can calculate and predict the area affected by leakage events. With modeling done, will get map of concentration and impacted area. The direction and magnitude of the impact of pollution will be known immediately and the potential losses that may arise will be minimized.

Abstract
The coastal area of Buleleng was chosen as a research location because it has a high diversity of coastal resources that very useful to local people to helps increase their income. However, there are various geomorphic processes that occur in Buleleng, which result in coastal dynamics in that area. This condition may trigger damage to the coastal environment, such as coastal erosion due to tidal waves. Wave activity and wave characteristics in the coastal area of Buleleng becomes an interesting phenomenon to be studied related to coastal dynamics in that area. Moreover, several high-wave events in Buleleng in recent years have caused damage and losses in the fisheries and tourism sector. This study aims to measure the dimensions of the waves in the coastal area of Buleleng and to identify wave characteristics in the coastal area of Buleleng. We used an integration between field observation, empirical approaches, and secondary data from Meteorological, Climatological, and Geophysical Agency to achieve the aims. The acquisition of wave data through a field observation is made by observing the situation at sea level and also on land based on the Beaufort Scale. The observation results are then integrated with the results of empirical measurements, i.e., measurement of wind direction and speed, wave period, and the beach slope in the coastal area of Buleleng. The expected results are the information on wave characteristics that can be used to formulate disaster mitigation efforts based on high-wave events in the coastal area of Buleleng, North Bali.
