Abstract
Abstract. Higher education is one of the most critical stages of education in a country. Most experts in various fields become proficient through higher education. Therefore, providers of tertiary education or tertiary institutions must continuously improve the quality of their education. One way to improve its quality is by mapping university excellence. This mapping was held to see the advantages of each provider in Indonesia. As an education center, as well as a research center, one that can be used as a basis for mapping is scientific publications. In this study, the advantages to be seen refer to the RPJPN 2005-2025 and RPJMN 2015-2019 and mapping based on the journal in SCOPUS 2014-2018, which is focused on Health and Medicine. The results of mapping with three tertiary institutions with the most publication journals, namely UI, UGM, and UNAIR, the majority of which published journals in the field of health and diagnostic technology and other tertiary education, were still in the lowest vulnerable range of 97,9%. This mapping was carried out by the Ministry of Research, Technology and Higher Education (KEMENRISTEKDIKTI) of the Republic of Indonesia with a research assignment research scheme for strategic policy studies with a focus on Health and Medicine. Higher education will be encouraged to continuously improve the quality of their education.

Abstract
Pandeglang Regency has the potential tsunami disaster because it is located close to the megathrust segment of the Sunda Strait. The tsunami disaster caused negative impacts such as death, property loss, and damage that could be reduced by carrying out disaster risk reduction programs through strengthening community resilience. Resilience is related to the ability of the community to recover from shocks or pressure to the original state, a resilient community is able to return to the previous state relatively quickly. It is important to know the tsunami disaster resilience index in Pandeglang Regency to obtain recommendations or concepts for tsunami disaster mitigation that are appropriate in creating community resilience to tsunami disasters in Pandeglang Regency. The purpose of this study was to measure community resilience to the tsunami disaster in Carita, Pandeglang Regency using The Integrated Concept of Community Resilience (ICCR). This method has been modified and adapted to the conditions of Pandeglang Regency. Measurement indicators are developed based on internal and external factors that affect community resilience such as social, cultural and economic capital, risk governance, and spatial planning. The methodology used in this research is primary and secondary data collection methods. The analyses were based on data from household questionnaires, focus group discussions and in-depth interviews then translated into indicators that are analyzed statistically.

Abstract
Indonesia, as a developing country, has a long-term national vision to become a stable industrial country which will achieve in 2035. This commitment showed by an increase in industrial sector contribution to Indonesias GDP, which is targeted to reach 30% in 2035 compared to 20.97% contribution to GDP in 2015. The global competition and current trends also become challenges for Indonesian industry sector where nowadays, international markets more prefer eco-labeled products than the conventional one. The green industry concept, which prioritizes the efficient use of resources sustainably to improve environmental performance, could be the answer to tackle both problems. Green industry development can be done through the concept of industrial symbiosis by implementing a waste exchange strategy. This strategy is applied by reusing waste as raw material for other industries. This study examines industrial symbiosis potential practices in Indonesia using waste exchange strategies in various industrial sectors through a mental model approach. The mental model structure in this study was built by exploring possible synergies between industries through by-product similarity. This preliminary study may serve as additional industrial planning guidance for the Indonesian government and other related stakeholders in the green industry development.

Abstract
To fulfill the Paris climate agreement the Indonesian government aims to increase the share of renewable energy. Among others it aims to install 6.4 GWp of photovoltaics (PV) until 2025. However the 2018 installed capacity of total PV is only 52.6 MWp. A new regulation for solar rooftops came into effect in January 2019 to give more security for investments in solar projects. But for a majority of consumers, the implementation of the regulation and an economical operation of a PV system brings many hurdles. A 10 kWp PV on-grid system at UKRIM University is monitored to gain information about energy data, Return of Investment (RoI) and levelized costs of energy (LCOE). Based on the monitoring results, three different consumer types (social institutions, household and offices) are analyzed in respect to profitability. For the PV installation at UKRIM an RoI of 15 years is calculated. The LCOE is calculated as 0.051 USD/kWh and thus higher than the feed-in price of only 0.042 USD/kWh. The current 10 kWp PV system can offset 70% of the electricity demand of the building it is connected to. Nevertheless the most economical size would be only 7 kWp, showing that the most ecological (zero net energy) and the most economical system (fastest RoI) can differ greatly. The slow RoI makes a PV on-grid system economically not interesting for social tariffs. Though households and office buildings can achieve a faster RoI, mainly because of higher electricity prices. The current regulation is economically not attractive enough for buildings with a social electricity tariff. Optimizations of PV systems in interaction with the connected load and the load profile can lead to a faster RoI and lower LCOE, making a PV-rooftop system more attractive.

Abstract
Urban farming through aquaponics has begun in Kelurahan Kandri, Semarang since 2016. More than eighty people, both public and private, formed an aquaponics community. This community has conducted routine training on aquaponics to develop urban farming through this system elsewhere in Semarang. In fact, it did not increase significantly, the number of aquaponics was unstable, sometimes increasing or decreasing. Therefore, the purpose of this research was to find out the motives and dynamics of the aquaponics community as aquaponic actors in supporting urban farming. The method of this research used a qualitative approach with purposive sampling. The results of studies with the analysis of the theory of motives and group dynamics show that this community was in the class of altruism and collectivism motivation so that it has a chance of sustainability even though at certain moments it decreases. As for the dynamics of some aquaponic actors who think that they weren-t in line with expectation, factors emerge that weaken the community in aquaponic. However, those who have psychological and social motives will tend to survive because they got personal satisfaction and a good impact on their environment. Therefore, when many aquaponics actors leave this system, they keep trying to return to carry out aquaponic activities in support of sustainability of urban farming in Semarang.

Abstract
The wastewater treatment process has various kinds of problems that can disturb and hinder the treatment process. Problems that usually occur are wastewater contains strong and irritating odor. Based on the production of different amounts can change the characteristics of effluents. The amount of organic variation decreases the effectiveness of biological processing and others. So based on this a good solution is needed and can expedite the treatment of wastewater. Bioactivator is an excellent material that can be used. Bioactivator consists of naturally occurring microorganisms attached to organic compost. It quickly stimulates the bacteria in situ so that the waste quickly decomposes. In the process, it prevents the generation of smells. Bioactivator is entirely natural and it does not contain any hazardous or poisonous chemicals or enzymes. Bioactivator also prevents the generation of odors, increases the metabolic of bacteria. It is most effective on organically overload treatment plants it increases treatment plant capacity. Bio activators can come from soils where soils contain lots of microorganisms. The amount of microbes found in the soil depends on the type of soil. Soil consists of micro and macrofauna and flora which provide a large carbon source and a large number of microorganisms. So in this paper by utilizing microorganisms in the soil as a bio activator for wastewater treatment.

Abstract
Brackish water has a salt content between 500 to 17000 mg/l. If people consumption of brackish water, it impacts health problems and making plants wither or die. Groundwater become brackish is caused by sea water intrusion. Therefore desalination technology is needed to process brackish water into fresh water. Natural material is predicted to be an alternative for desalination process. Natural zeolite are more used because they have abundant excess availability, lower operational costs, and have a high adsorption. More research is needed to determine the right activation method for zeolite so that the effectiveness of decreasing salinity can increase. In the initial study using natural zeolites with chemically activated, the reduction efficiency (ɳ) reached ~ 99.54%. From the results of these natural treatment, zeolite have the ability to reduce of salinity. This article is a review of several previous studies.

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
This study explores the conditions of families in the suburbs of Bandung in caring for their children while they work in factories. This study uses a qualitative approach to get the natural state of society. This study also uses family integration theory because the theory can direct researchers to industrial societies that can have a significant impact on family conditions and suburban communities. This study found that to carry out their economic functions, mothers in the family worked to the factory. For this reason, their children are entrusted to their neighbors and schools that indirectly reduced their intimate with their families. Families in the suburbs do many conditions like this so that it conflicts with traditional patterns of childcare. For the sake of child development, some people suggest holding childcare institutions rather than just being entrusted individually to other families.

Abstract
Jatibarang Reservoir is located on the Kreo River. This reservoir functions are as a flood controll, water supply and hydroelectric power. The total capacity is around 20.4 million m3. The spillway is designed at elevation +148.9 with a width of 15 m, capacity Q50 = 240 m3 / s, and an emergency spillway at + 151.80 m, width of 60 m with a capacity of 1350 m3 / s. This paper aims to evaluate the performance of reservoirs in their function as flood control, due to land use changes in upstream of the reservoir catchment area. The method which was used is the HEC HMS. Land use map data is used of 2016 and spatial planning map of Central Java province for 2011-2031. The results were obtained the hydrological parameters increase in CN and imperviousness, decrease in initial storage and initial abstraction wich resulting in increased of flood discharge. The impact of this, an emergency spillway that was designed for discharges greater than Q50, must function at discharge that smaller than Q50. Initial design, Q50 water level elevation below +151.8, but with the change in hydrological parameters, water level elevation of Q50 increase up to + 152.2

Abstract
Cold storage for storage at low temperatures so that the performance of bacteria and microorganisms that destroy food can be reduced. Maintaining the quality of fresh fish in storage above freezing temperatures requires special treatment so that quality degradation can be delayed and the storage can be extended. The use of ozone as a disinfectant can provide a solution to the problem of decreasing the quality of fresh fish. The combination of an ozone generating plasma machine with cold storage gives a great advantage in storing fish in fresh conditions. Storage of fresh fish at a temperature of 2-8 ° C can reach a shelf life of 15 days and extend the economic life of the fresh fish. The use of ozone generating plasma technology in cold storage can provide space for increased energy efficiency and economic value with the intensity of energy consumption three times less than without the use of plasma technology, meaning that it can provide a three-fold benefit in terms of energy costs per kilogram of fresh fish per day. Increasing the shelf life and decreasing the intensity of energy consumption is very important in the food distribution chain, especially for fresh fish that are very vulnerable to damage.

Abstract
Land use, lithology, time, rainfall and human activities cause changes in river water quality physically, chemically, and biologically. Waste pollution from non-point sources is difficult to control where it is spread with a large enough accumulated discharge. Some watersheds in Indonesia have specific non-point source pollution sources such as batik waste originating from MSMEs. The research case study is in the Premulung river segment of the Solo City. This study explains the effect of various pollutants on water quality such as batik waste and domestic waste. Premulung River water samples were taken at 13 points from non point source and 10 point source. The prediction model uses Qual2kw software. The results showed that batik waste discharges from MSMEs affected water quality on COD parameters and colors temporarily and quickly changed along the river channel. The river that contains batik waste has a characteristic dark water with high suspended material. The presence of batik waste discharges accelerates the river sinking process.

Abstract – The increasing demand for energy from year to year is not balanced with the availability of energy resources. So that the utilization of existing energy must be carried out economically and efficiently according to Goverment Regulation No. 70 of 2009 and no exception in the academic environment. College as a place to gain knowledge, in their daily lives there are teaching and learning activities that require adequate lighting. Observations are made to see if the existing lighting system by the recommendation of the SNI or not and how the savings opportunities that can be done. This study uses a quantitative method by taking samples from 6 rooms which measured their illuminance and compared with the standards of SNI 03-6197-2000. Based on measurements and observations results, the opportunities for savings can be made by adjusting the number of light, set the time lights on, and how long the light is used. If these steps are implemented then we will get savings of up to IDR 569.203.200,- per year for 6 rooms from energy consumption on lighting systems.

Abstract
Hydrogeological survey activities have been carried out with the aim to identify potential water pollution in the Girimulyo area, West Progo. The research method was conducted with a field hydrogeological survey to get hydrogeological data and water quality in the form of pH and TDS. Water quality status evaluation is done by determining the pollution index based on water quality standards. The results showed that the water in the study area was generally colorless, tasteless and odorless and clear (not turbid). The pH value of water measured in the field is 7 - 8.1, while the TDS is 15 - 305 ppm. The results of the water chemistry laboratory test show that groundwater quality is quite good with a pH of 7 - 8.1 and TDS 112-240 ppm. Groundwater violence is in the middle to medium class - hard, as is river water. Chemical types develop as groundwater Ca - bicarbonate and Ca, Mg - bicarbonate. The index of water pollution studied is in the mildly polluted category (Pollution Index of 1,81 – 4,81), with the greatest level of pollution found in river water in Niten.

Abstract
Water loss is a serious problem in the world of drinking water management. In addition to disrupting services that result in economic losses, pipe leaks can cause health problems if contamination occurs. In this paper, the author will conduct a potential risk analysis of the causes of water loss to address technical problems in the management of transmission and distribution pipelines in the Regional Water Supply System of Bregas in Central Java, Indonesia. The author tries to present a simple method for assessing the potential risk of water loss from the physical aspects of the network and the environment with passive control. Passive control is a reaction to leaks that are usually reported by customers or recorded by company staff. In this study it was concluded that the pipe condition had the highest potential risk compared to other factors. And transmission pipelines from Kaligiri and Gombong springs are considered to have the highest risk of water loss. Although incomplete, this research can be a valuable reference source for practitioners and researchers dealing with water loss management in distribution systems and providing a road map for future research.

Abstract
The competition in sports is getting tougher, and the drives to achieve better result has led the athletes to indiscriminately use dietary supplements, including herbal ones. Fruits relatively can acts as a support in health and exercise thanks to its rich content of macro- and micronutrients, fiber, minerals, vitamin and a number of bioactive phytochemical components. The aim of this study is to review and gather information on tropical fruits which is capable to improve athletes performance and its prospect to be developed into nanosupplement. This review examined online literatures via PubMed, Sciendirect, and Google Scholar. Based on the literatures, the exercise performance can be improved by various compounds found in tropical fruits such as banana, cherry, grape, pomegranate, and watermelon. Overall, tropical fruits can aid sports performance by improving physical strength, increasing the recovery in injury, attenuate muscle soreness, and reducing fatigue. It is suggested that there is possibility to apply nanotechnology to formulate fruits based sport supplement in the form of nanoparticles.

Abstract
Thekelan Hamlet is one of the tourist hamlets in Kopeng District, Semarang Regency, Indonesia, which is near the Gunung Merbabu National Park area. Furthermore, the potential of biomass from the livestock and agricultural sectors in this village has not been well utilized. The purpose of this study is to determine the amount of energy use in the Thekelan hamlet, and analyze the potential use of renewable energy (biogas) to substitute conventional electricity. The method used in this research is descriptive qualitative combined with IPCC default methods based on a questionnaire from 40 respondents taken randomly. The result of the research shows that the use of energy sources from fuel wood is 9,830 kg and LPG is 215.5. The number of cattle in the hamlet of Thekelan is 70 heads and 34 goats. The largest GHG emissions are generated from the use of fuel in animal husbandry activities with a value of 0.206 Gg CO2e / year while the lowest GHG emissions from LFG utilization activities are 0.008 Gg CO2e / year. The total emissions of all activities are 0.599 Gg CO2e / year. The use of biogas as an alternative energy is known to be able to reduce GHG emissions by 34.3% because the substitution of fuel wood and LPG is transferred to the use of biogas. This research is expected to be a stimulant and basic data for the realization of low carbon energy conscious villages.

Abstract
The use of plastic products nowadays almost comply all needs because of plastic products have advantages such as being more economical, flexible and lightweight. Yet, Environment and Sustainability become important issues for company and society. Companies must reproduce and recycle all plastic products related with that issues. CV Jordan Plastics in producing M500 bottles often produces reject products exceeding the target set by the company. This research was conducted to determine the current process capability in producing the M500 bottle, where the process capability index can be calculated from the results of control chart whose data is considered to be statistically controlled. Multivariate control chart can be used to control the quality of the process at CV Jordan Plastics, because the quality characteristics of the products are more than one and the controls must be carried out together. Correlated variables that are used in making multivariate control chart are different of thicknesses, leaks, and dents. The results of the T2 Hotelling control charts show that the process has not been controlled, because there are 4 observations that are out of control. From the Mason, Young and Tracy (MYT) decomposition results, it is obtained that the variables that cause observations to become uncontrolled are different of thicknesses and dents. After revised the control chart, it is known that the current multivariate process capability index is 0.79, which means the process is not capable yet and needs to be improved. The proposed improvement are given to solve the problem of different thicknesses is to position the die right in the middle so that the thickness on all sides is same and for dented conditions can be reduced by setting the temperature and blowing pressure according to the standard.

Abstract
Delays have been identified as one of major risks in oil and gas projects. A sound risk analysis is, therefore, one of a key factors for the success of the projects. The aim of this research was to measure the impact of delay risks on the completion time of an oil and gas project in Indonesia as a case study. Data of relevant delay risks were initially collected from literature reviews and observations on project documents, and finalized through interviews with key respondents of the project. A monte-carlo based simulation software was used to simulate 28 delay risks identified, and applied on the 34 project activities. This research found the probability of less than 1% for on-time project completion according to the baseline schedule (366 days). It was also projected that the project duration could be extended by 10.6% (405 days) and 14.2% (418 days) with 50% and 80% probabilities, respectively. The sensitivity analysis indicated that the most influential activity on project delays was the tubular delivery, and the risk delay with the greatest impact to project delays was the delay of long-lead item delivery. These research showed the mechanism of incorporating delay risks into relevant project activities, and the findings allow better understanding of stakeholders to develop appropriate risk mitigation strategies.

Abstract
The growth of infrastructure development is currently increasing rapidly due to the increasing population. One of them is residential development. The construction carried out will produce construction waste. The existence of construction waste needs to be monitored to support good waste management. The purpose of this study was to determine the construction waste index in each district / city in Central Java based on the number of households. The method that used in this research is to divide the number of households in each district / city by the number of households throughout Central Java. After that, the construction waste index value will be made into a monitoring map of the basic model of construction waste monitoring. The results show that the district / city with the highest construction waste index value is Brebes Regency which is 0,053 and the district / city with the lowest construction waste index value is Magelang City which is 0,004. So it can be concluded that Brebes Regency is the highest producer of construction waste in Central Java and Magelang City is the lowest producer of construction waste in Central Java.

Abstract
The large population of regencies or cities in Central Java causes high consumption of plastics and after use will eventually be discarded. Plastic waste needs to be monitored to see differences in the level of plastic waste produced by each region and the preparation of further waste management plans. The aim of this study was to examine the plastic waste index in Central Java as a monitoring activity using population data. The method used in this study is to divide the total population in each district or city by the total population in Central Java. The plastic waste index value is calculated from year 1990, 2000, 2010, and 2018 to see its progress and will be made into a basic model or space monitoring model map using GIS. The result is that the highest plastic waste is Brebes Regency for the last 28 years with an average index of 0.053 and the lowest is Magelang City with an average index of 0.004. Information about the level of plastic waste in the area can be represented in maps through population data and becomes basic information that can be used for further research.
