Nowadays, The roads have increased the number of streetlights for the roads vehicles/pedestrians, which raises investment and energy. Observations made to obtain most of the road lights are always active at night, even when there are no vehicles or pedestrians on the road. The problems that occur are the waste of energy sources that are used in streetlights. This research designs the concept of intelligent traffic flow based (LED) for energy optimization, maximum efficiency. This concept uses intelligent light architecture using the LoRaWAN Mesh network. The application of this concept offers system reliability, reduces costs, and makes user satisfaction. The results of this study are demonstrated by experimenting with comparing conventional LED lights. The proposed system, resulting in 33% to 62% energy savings depending on when the usage process in streetlights. Smart lighting LEDs with LoRaWAN provide a remote-control mechanism that can be dynamically adjusted based on environmental conditions, distance, and automatic motion.

Aceh Province over the last 20 years has experienced different events that can be divided into 3 (three) phases. 1st Phase is the phase of the conflict (2000-2004), 2nd Phase is the post-earthquake and tsunami rehabilitation and reconstruction phase of Aceh (2005-2009), and 3rd Phase is the post-rehabilitation and reconstruction phase (2010-present). Events that occurred during the last 20 years are certainly likely to provide risks to community activities in the province of Aceh. One of the activities affected by the event is the construction project work. The implementation of construction works affected by events in Aceh Province over the last 20 years is highly vulnerable to risks that impact on achieving project objectives such as cost and time. This study analyzes the impact of the contractor and operational managerial risk factors on the cost and timing of construction. Data were obtained from questionnaires distributed to 15 large qualification companies in Aceh Province. Testing data is done by using the validity test and reliability test. Data that has been valid and reliable then analyzed by using Severity Index (SI). The variables of a managerial risk factor with SI to the highest cost in 1st Phase are F5 (incompetent Engineer), 2nd Phase is F3 (lack of contractor experience), and 3rd Phase is F5 (incompetent Engineer). From the operational risk factor, the highest cost SI in each phase is the G3 variable (electrical disorder). The managerial risk factors with the highest time SI in 1st Phase are F6 (lack of top management support), 2nd Phase is F5 (incompetent engineer), and in 3rd Phase is F3 (lack of contractor experience ). From the operational risk factor, the highest time SI at each phase is G3 (electrical disorder). © Published under licence by IOP Publishing Ltd.

A single ambient noise measurement has been found to be useful in investigating the near-surface geology in particularly for estimating site fundamental frequency. This single microtremor method is very attractive and has been successfully applied in many projects as the method is non-destructive, low cost, feasible for urban environments, fast, and deep penetration. Furthermore, this single microtremor method has been successfully applied in many projects. This paper presents the application of the single microtremor method to estimate the site fundamental frequency at a site in the historical city of Byblos, Lebanon. Pre-processing of industrial origin detection was carried out. Several durations of the measurements were investigated to obtain the most stable results. The site fundamental frequency was validated using one-dimensional site response analysis. The results are presented in this paper. © Published under licence by IOP Publishing Ltd.

The impacts of climate change in the last decade are tropical storms, rising sea levels, and forest fires. These impacts damage human health, natural resources, and gender equality. This study aimed to identify the effects of climate change in the community, cultural development, and gender roles in addressing climate change in Central Kalimantan. This study used a cross-sectional design with questionnaires. Data collection was carried out using interview and observation techniques with a purposive sampling method. Interviews were conducted with 30 respondents in each district. The results of the study showed that the community has long felt climate change in Central Kalimantan. Still, they do not yet understand that changes in rainfall and temperature patterns reduce environmental conditions and forests' function to support daily life. The openness of access to natural resources for women gives the responsibility of maintaining families during climate change, for example, utilizing plants to be used as weaving material in managing wet and dry forest ecosystems that increase deforestation rates. In the future, stakeholders, including regional government, will issue policies that protect women's rights and interests to ensure that women get the same access and benefits related to information and decision-making, especially in natural resources management. © The Authors, published by EDP Sciences, 2020.

Higher education is an education unit that organizes higher education. College students are called students, while college educators are called lecturers. Higher education as a place of learning and self-development Students provide facilities to improve student achievement in the form of student achievement scholarships. This scholarship program is expected to stimulate students' interest in learning to be better. In determining scholarship recipients, the student division selects prospective scholarship recipients based on existing criteria. In the selection process, the student division has difficulty choosing the data of prospective recipients. Because each type of scholarship criteria and has different criteria weights. Calculation of the value of weighting criteria requires precision. Based on the problems that occur, the author designed a decision support system to determine the recipients of achievement scholarships using the SAW method. This system can help student affairs to carry out criteria for recipients of achievement scholarships based on administrative data of prospective scholarship recipients in determining criteria for weighting value calculations. With this system, it can minimize errors to determine prospective scholarship recipients who excel. After testing the use of support systems for deciding scholarship decisions using the SAW method, it can be concluded that a decision support system can assist the student's part in carrying out their duties. © 2019 IEEE.
