Many researches on the low-cost solar simulators for PV module performance testing have been carried out. However, it was found that the previous designs require improvements to address the needs of PV module performance test equipment specifically for dust impact experiments. As the dust material attaching on the surface of PV module is removed easily during experiments, module position should be kept to face upwards. This study reported results of a solar simulator developed for testing characteristics of PV modules including those contaminated with dust. Test results showed that the solar simulator worked well. Voltage input and distance of halogen lamps can be adjusted to produce various light intensities received by the examined PV module. Relative difference of maximum power output (Pmax) of an examined PV module exposed to the Sun and the developed solar simulator was about 33%. The large difference was likely contributed to human errors and non-standard equipment applied during the study

The three dimension of Sustainable Tourism Development (STD), namely environmental, economic and social have been carried out with various approaches. Although these three dimensions influence each other and cannot stand on their own, and are assumed to be supportive to each other and compatible. However, most studies focus on the environmental and economic dimensions. The social dimension gains less attention and is difficult to attain and operationalise. To implement STD properly and balanced, it is necessary to explore the social dimension of STDs to obtain a clear agreement on the concept of social dimension in STD, especially from Indonesia's perspective. The purpose of this study is to explore the boundaries of social dimension of STD. This research is an exploratory study that aims to develop knowledge that is still new in nature and to provide direction for future research and also to fill gaps or shortcomings of the concept and definition of social aspects within the framework of STD using a systematic literature review. The result of the study is a concept of social dimension of Sustainable Tourism Development.

Lasiana Beach is a particular tourism site located in Lasiana Sub District, Kelapa Lima District, Kupang City. The lack of development and poor management renders the site to be unattractive to visitors.

This study aims develop new innovation of concrete mixing using household waste by substituted 15% glass crushed of the total weight of fine aggregate to polypropylene fibers concrete to get compressive strength. The result showed that BK and BS have a higher compressive strength than BN with the precentage increase of 13.82% and 18.53% at day 28. This study become a solution of waste problems by utilizing glass waste as an alternative to added concrete is very effectively

Traffic volume that exceeds the existing road capacity occurs on Jalan Piet A. Tallo during peak hours condition. Congestion often occurs in the mornings and evenings. In addition, there is a merging of the 4/2T road segment into 2/2TT which results in a buildup of traffic flow at that point so that some vehicles have to move outside the body of the road. This illustrates that the traffic flow and capacity of this road section are not proportional to the traffic volume at peak hours. Analysis of the capacity and performance of roads is based on the PKJI 2014. The results show that the performance of Jalan Piet A. Tallo Kupang in current conditions is heavily loaded because it exceeds the capacity of the road so that a queue of vehicles moves and stops alternately

Performance of a photovoltaic (PV) module is influenced by the amount of solar irradiation received by its cells. One of the trigger factors of PV performance degradation is shading due to passing clouds and high objects surrounding the PV area. This study aimed to examine the impact of shading on the performance degradation of polycrystalline (pc-Si) and mono-crytalline (mc-Si) modules – common PV technologies installed on solar home systems in Nusa Tenggara Timur (NTT) province, Indonesia. The shading patterns were simulated to cover the modules horizontally and vertically. Experimental results showed that short circuit current (Isc) and open circuit voltage (Voc) generated by the two solar module technologies decreased proportionally with the increasing of shading levels. Compared to the Voc, Isc was the more affected parameter caused by shading. Furthermore, it was found that mc-Si was the technology that accounted more degradation than pc-Si.

Bolok crossing port is one of the passenger ports that serves as a means of supporting sea transportation going to or coming from Kupang District.In this study the data collection technique used was a qualitative method by observing and interviewing directly to informants using Bolok Crossing port services and quantitative methods by taking primary data, namely questionnaires and secondary data collection obtained from the Department of Transportation (ASDP). This study used the Importance Performance Analysis (IPA) and Customer Satisfaction Index (CSI) methods. The results showed that there were factors influencing the assessment of service users towards the Bolok Crossing Port service for transport passenger service users and transport crew service users and the perception of service users (transport passengers) and the perception of the service crew transport/driver (vehicle transport) visitors to the Port of Crossing Bolok

An adsorption process is able to filter out solid objects in used oil such as dust, scrap metals and charcoal from burnings so that the color of used oil is not too dense even though it is still black. The pyrolysis process can improve the color of used oil so that it becomes clear yellow like new oil, even though it does not meet diesel engine fuel criteria. The mixture of used oil from the pyrolysis process with diesel fuel still meets the characteristics of diesel fuel because the results are close to the characteristics of diesel fuel. Research results show that the mixture of used oil in diesel engine fuel if used as fuel can save 10% of the fuel because the power and efficiency when compared with pure diesel fuel is almost the same, but the exhaust emissions are large if the percentage of used oil in fuel is increased
