Authors: Rahdriawan M , Arriani R R 
Published: April 2020

Abstract
Urban farming through aquaponics has begun in Semarang, since 2016. More than eighty people formed an aquaponics community. The community has conducted routine training on aquaponics to develop urban farming through this system. But the number of aquaponics was unstable. Therefore, the purpose of this research was to find out the motives and dynamics of the aquaponics community in supporting urban farming. The method of this research used a qualitative approach. 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 actors who think that they weren’t in line with expectation, factors emerge that weaken the community in aquaponic. However, those who have altruism and collectivism motives will tend to survive because they got personal satisfaction and a good impact on their environment. Therefore, when many actors leave this system, they keep trying to return to carry out aquaponic activities in support of urban farming in Semarang.

Published: April 2020

Abstract
Jajar River is geographically located between Demak and Grobogan Regency area. For most part, Jajar River which lies on lowland area is mainly utilized for agricultural purposes. The utilization of the land around the area of Jajar River might potentially cause several environmental problems such as river water contamination, causing degradation of river water quality. Generally, river has the capacity to purify itself by decomposing any pollutants blended in the water. This capacity is called self-purification. The aim of this study is to determine the level of self-purification capacity (time and distance of water purification) using Streeter-Phelps equation, by obtaining data about organic pollutant concentrations DO and BOD at a certain pollutant point in a river. By using Streeter-Phelps equation, it is expected to find oxygen reduction curve toward time and distance. Deoxygenation and reaeration constants are needed to draw the curve. Moreover, Streeter-Phelps equation can generate the oxygen reduction curve which shows self-purification distance. The results showed that there was no natural purification process in Jajar River. In other word, the water sample test in each segment showed the existence of waste input, which was indicated by unacceptable results of DO and BOD parameters. In this condition, the river ecosystem had not been able to purify the water from BOD input. It supposedly happened due to the inability of DO concentration to return to the ideal condition of anaerobic river from waste contamination in the extended segments.

Published: April 2020

Abstract
As one of the province that borders DKI Jakarta, West Java has been named the most populous province in Indonesia. This has an impact on land cover change in the region. For example, a lot of land that was once a vegetation land, is now converted into built up land. From previous studies, changes in land cover are caused by several factors, one of which is the existence of cities/regencies in the West Java region itself. However, is yet known for certain that changes in land cover are influenced by only the closest city/regency or all cities/regencies. Therefore, an analysis of the influence of cities/regencies existence towards land cover change in West Java is needed based on geospatial data. One calculation method to determine the influence of cities/regencies existence towards land cover changes is Binary Logistic Regression (BLR). BLR is used to analyse binary phenomenon. This study shows that to determine land cover change at a point in the province of West Java it is sufficient to be seen not only from the influence of the closest city/regency, but also necessary to be seen from the influence of all cities/regencies.

Abstract
Soap nut (especially Sapindus rarak De Candole, can also be S. mukorossi) or also known as rerek, lamuran or lerak is a plant that is known for traditional detergent. Batik is usually recommended to be washed soap nut because it is considered as the most suitable washing agent to maintain its quality (batik color). Soap nut seeds contain saponins, a toxic alkaloid, these saponins produce foam and function as a washing agent, and can also be used as a cleaner for various kitchen utensils, floors, and even bathe and clean pets. This research aims to compare the quality of CV Rena batik soap nut detergent with batik soap nut produced by other industries. In this experiment include color analysis, odor analysis, pH analysis, density analysis and viscosity analysis of tested batik soap nut detergent. The results of the five sensory organoleptic tests found that CV detergents were compared with three competitor manufacturers batik soap nut detergent (detergent A, detergent B and detergent C) has a homogeneous shape, distinctive color and distinctive odor. While for the pH test the CV Renault detergent results were pH = 3.2, detergent A pH = 3.8, detergent B pH = 5.9 and finally detergent C pH = 4.2. For the density test, the detergent density of CV Rena = 1.0386 gr/ml, detergent A = 1.0255 gr/ml, detergent B = 1.0554 gr/ml and detergent C = 1, 0068 gr/ml. And for the viscosity test, the result of CV Renas detergent = 1.61 cp, detergent A = 1.45 cp, detergent B = 5.86 cp and detergent C = 1.15 cp. The trial results obtained in organoleptic tests such as color, odor and shape are in accordance with the Liquid Detergent Quality Requirements SNI 06-4075-1996, while the pH and density are not in accordance with the existing quality standards. Suggestions for this research are to use more soap nut extracts so that the density produced will be thicker and in accordance with the existing SNI and use natural ingredients which have not too acidic properties to conform to the established SNI.

Abstract
Indonesia is boosting electricity supply, where coal fired power plants are most widely used. Burning coal activity will produce Fly Ash Bottom Ash (FABA) that categorized as Hazardous and Toxic Substances. The production of FABA are 6.598.493 tons (2019) and will increase along with the 35, 000MW program. The research purpose is to study the utilization of FABA from PLTU Labuan Angin as road pavement material that not only fulfill required specifications, but has better performance and environmentally safe. The experimental method was chosen by laboratory testing. Criteria for utilization of FABA as road pavement material, must be carried out with the use of material that capable to binding FABA so that it doesn’t disintegrate Test results showed that FA is type F with CaO levels <10% and LoI 4.27%. Characteristics testing also showed results such as specific gravity of FA 2.64 and BA 2.56, absorption 3.24%, sand equivalent 95.35%. Utilization for base layers with a composition of 75% BA, 25% FA, and 9% PCC produce γd 1.71%, Wopt 5.84%, and UCS 33.05kg/cm2. This utilization is the most effective, because it absorbs more volumes, binding cement, and compaction with heavy equipment can also prevent FABA from released so it is environmentally safe.

Published: April 2020

Abstract
Land is one of the important resources that can be used to supply the needs of human life. Uncontrolled land utilization will cause land cover change phenomenon. Land cover change phenomenon can be analyzed by using a model. To get an accurate result, the selection of models in the analysis of land cover change must be based on the characteristics of land cover change phenomenon itself. Land cover change is a binary phenomenon and strongly related to the local characteristics of a region. A model that can be used in the analysis of binary phenomena is Binary Logistic Regression (BLR) model. However, the application of BLR model has a disadvantage. BLR model is one of the global models which assumes that the analyzed phenomenon has homogeneous characteristics for the entire study area. This does not correspond to the characteristic of land cover change phenomenon. Therefore, we need another local model that is able to show local characteristic variations of land cover change. Geographically Weighted Regression (GWR) model is one of the local spatial regression techniques that can be used to analyze phenomena that have spatially heterogeneous characteristics. The application of GWR model for binary phenomena (dependent variable) such as land cover change is called Geographically Weighted – Binary Logistic Regression (GW-BLR) model. This research aims to analyze land cover change phenomenon in the Northern West Java development region using GW-BLR and compares the result to BLR model. The results of this research indicate that the analysis of land cover change in the Northern West Java development region using GW-BLR model has a higher level of accuracy compared to BLR model. The modeling results of land cover change using GW-BLR model has an overall accuracy value of 91.10% and using BLR model has an overall accuracy value of 84.09%. Therefore, it can be concluded that land cover change phenomenon in Northern West Java development region can be analyzed more accurately by considering its local spatial characteristics through using the GW-BLR model.

Authors: Camila T R , Saraswati R 
Published: April 2020

Abstract
Balikpapan City located in the east coast of Kalimantan Island. The city of Balikpapan is directly adjacent to the Makassar Strait. The problem faced by Balikpapan City is the function of the land, namely the reclamation of the construction of shopping centre which results in changing the shape of the coast so that it has the potential to experience abrasion. In the city of Balikpapan for the past 6 years there has been an abrasion of 40 meters which has resulted in a decrease in Regional Original Income (PAD). Research on the vulnerability of the east coast of Balikpapan City to changes in coastline in 2005 and 2018 was focused on the calculation of social vulnerability and changes in coastline analyzed using crosstab. This study divides the area based on the shape of the beach, namely fine sand beaches, coarse sand beaches, and thick beaches. Based on the results of the analysis there are three levels of vulnerability, namely low, medium, and high. Areas with a high level of vulnerability are found in the rough sand segment. The level of vulnerability is along the fine sand beach segment and the low level of vulnerability is along the shore coast segment.

Published: April 2020

Abstract
The residents of the floating village of Malahing, Bontang, East Kalimantan, earn their living as fish catching fishermen and seaweed farming. Residents even experience a clean water crisis, every month they require a budget IDR 300, 000 until IDR 400, 000 to buy clean water at Tanjung Laut by ketinting. The PKT programmed rain harvesting for Malahing residents to supply clean water. The method used was field observations and surveys as well as simple calculations using the program of Office Excel. The PKT carried out gutter procurement for every resident’s house, provided three plastic drums of 200 litres to collect rainwater, provided filters to filter rain water, train the residents to care for and repair the filters. As a result, the residents get clean water to meet their daily basic, grow vegetables for family needs and do greening in their yard and water them. They can also water communal latrines so that defecation is not carried out at sea. Malahing residents can save IDR. 356, 000 until IDR 456.000 per month, help save fossil fuels and reduce carbon dioxide emissions so they become healthier, prosperous and environmentally friendly.
