Fishing can be done in various ways, including by utilizing lights as fishing tools. The lights used for fishing tools are varied, ranging from torch lights, pressure paraffin lamp, fluorescent lamps (TL, PL, SL, CFL), mercury, and various types of led. However, light transition between one colors to another often scares the fish, driving them out of catchable area shocked by the color change. One solution to address this problem is by smoothly switching the color of the lamp using Pulse Width Modulation (PWM) system on the microcontroller. The color used are the lamp with basic colors of red, green and blue. With power capacity of 50Watt/12Volt, this lamp is classified as High Power Led (HPL) lamp. The light can be free- adjusted, where each lamp can be turned on by its own light or can also be turned on in combination. It can slowly be switch on from an off position to maximum and also can be dimmed from maximum to off. Thus the intensity of the light can be controlled. The HPL and control sections were created separately. Tools and materials used are consist of push-button, microcontroller, optocoupler, mosfet and Red, Green and Blue HPL, Radio-meter (ILT5000 Research Radiometer), Voltmeter, and Amperemeter. The method used was experimental in both laboratory and field. The result of research is in the form of RGB HPL lamp which can be adjusted through control system, such as adjusment for each lamp, or light combination with smooth color transition. Thus, when this technology is applied as fishing tool in liftnet fishing, the targeted fish would still remain on catchable area.

Wall is the wider component of high-rise building to exposed the sunshine than roof. The building wall in tropical countries receives the solar heat all day and it makes temperature rise of its room and becomes less comfortable. Therefore, a wall with good thermal insulation is needed for buildings in tropical countries. Lightweight foamed concrete (LFC) can be used as a wall brick substitution as well as thermal insulator. The experimental research about LFC was investigated using FA and foam content to the thermal conductivity of LFC. The investigations were performed through the measurement of thermal conductivity, material density, and observation to the morphology of LFC surface. The LFC samples were varied in volume fraction of foam and FA in mortar. The result shows that the increase in volume fraction of foam in all variations of FA content decreases its thermal conductivity. In contrast, the increase of FA content in LFC results in an increase in thermal conductivity until 45 wt% of FA content, then it decreases as the addition of FA. Thus, the optimum thermal conductivity of the LFC was obtained by FA of 45 wt%. The relationship between thermal conductivity and LFC density shows that any increase in LFC density resulted in an increase in thermal conductivity. Otherwise, any decrease in LFC density resulted in a decrease in thermal conductivity.

Estimated relative permittivity performed on soil is essential for forecasting the performance of Ground Penetrating Radar (GPR) in an in-depth manner. This study investigated and verified the empirical relationship model between relative permittivity and volumetric water content in soil to predict the relative permittivity of contaminated laterite soil. In this study, a 24-hour measurement involving 800 MHz shielded antenna GPR was carried out in a concrete simulation field tank filled with Terap Red soil (1.5 m x 2.6 m x 1.5 m) at UiTM Perlis, Malaysia. Embedded moisture content probe was simultaneously measured to monitor the response of volumetric water content in contaminated soil in order to formulate an empirical relationship between relative permittivity and moisture content. The GPR data were pre-processed and filtered with Reflexw 7.5, while regression analysis was performed to evaluate the empirical relationship model. The model outcomes were retrieved from a number of cross-validation schemes, including correlation analysis (R2), root mean square error (RMSE), and calibrated Agilent Technologies Automated Vector Analyser (VNA). A third-order polynomial for analysis of variance (ANOVA) best fitted the model with positively strong correlation (R2=0.989, N=24, P < 0.01) and RMSE 0.003< RMSEpredicted < 0.19. Verification of the proposed model using calibrated VNA displayed exceptional agreement between 0.06% comparisons.

作者： E Purnawanti N I Oktavitri D R M Isnadina N Fitriani Environmental Engineering Study Program Department of Biology Faculty of Science and Technology Universitas Airlangga Indonesia

This study aims to discover the obstacles and provide recommendations on the technical and institutional aspects of the chosen communal WWTP. The methods used in this study were field survey and questionnaire. the data were analyzed using quantitative, qualitative, and SWOT analysis. There are 11 out of 13 communal WWTPs that do not work optimally. The technical obstacle encountered in the operation of the chosen communal WWTPs is the huge building capacity that does not meet the criteria of HRT design. The recommendations for the technical problem include lowering the water level and reducing the number of baffles in communal WWTP. The obstacle faced in the operation of chosen communal WWTPs in terms of institutional and community participation aspects is that the maintenance is only known by few people. The recommendation for the aspects of institutional and community participation is for KPP to arrange a socialization on the maintenance of communal WWTP based on its maintenance module.

Universitas Sebelas Maret (UNS) is the biggest university in Surakarta Central Java Indonesia, which was established on March 11th, 1976 through Presidential Decree No. 10 of 1976. Commitmen of UNS toward Green Campus began in 2012 by Rector Decree 7nd of August 2012. Land size of UNS, whis is only 60 ha becomes constraints in development of Green Campus Initiatives. In 2030 agenda of Sustainable Development Goals gives attention to huge increased of urbanization thus cities and human settlements face the problems of high density, economies of agglomeration link economy, energy, environment, science, technology and social and economic output [2]. The Problem of Water and Sanitation becomes big issues of Sustainable Development Goals (SDGs), which is stated in the Goal 6 out of 17 Goals. Goal 6 not only addresses Clean water sanitation and health but also quality and sustainability of water resources all over the world. Universitas Sebelas Maret is one of Campus in Indonesia, which has awareness toward water and sanitation, especially related to the problem of waste. Liquid waste has become problems for a long time in UNS, when domestic liquid waste has come from residential areas surrounding campus passed through the lake in campus before finally flowing to Bengawan Solo River. This causes euthropication and sedimentation of the lake of UNS, which had impact on extremelly decreased the function of the pond estetically and functionally. By partnership with the Ministry of Public Works anad Spatial Planning in 2017, UNS has built Integrated Waste Water Treatment, which treats domestic liquid waste from residential area surrounding campus and internal campus becomes recycled clean water. In spite of that, UNS also treats organic waste of fall leafs through composting units and manages chemical hazardous waste according to the Indonesian regulation issued by Ministry of Environment. Several efforts of UNS related to Waste Management have contribution to achieving SDGs e

We report a density-functional coupled with vibrational calculation on justifying the isomerization pathway of cyclopropene to propyne. The idea is to present the pathway in energy level diagram which the transition state is ensured by tracking a particular mode that supports the cyclic bond breaking and triple bond formation to occur. This mode decreases along the pathway and disappears at the transition state. To verify the designed pathway, the activation energy of the isomerization is used to find the rate constant with respect to experimental data at 500 K and 700 K by using transition state theory (TST). At those temperatures, TST predicts the rate constant at the same order of magnitude with the experimental result. It shows that the trend between calculation and experimental data is qualitatively in a good agreement, which implies that the designed pathway is justified. Furthermore, this study can be used as a guide if one needs to construct an isomerization pathway.
