The growth of motorcycles which continues to increase every year can lead to an increase in the number of accumulation of motorcycles on the approach to the intersection, so it is necessary to plan a Exclusive Stoping Spaces for Motorcycle (ESSM). The purpose of this study is to find out whether the street at the research location meets the requirements for ESSM planning by reviewing the number of motorbikes piled up during the red phase and planning the ESSM design. The method used in this study is an experimental method in accordance with the 2014 Indonesian Highway Capacity Guidelines (PKJI) and the Technical Planning Guidelines for Special Stopping Spaces in urban areas. The results of the study show that ESSM at signalized intersections in urban areas in Merauke City can be implemented in the next 15 years, namely in 2037. Of the four arms of signalized intersections, only 3 approaches can implement ESSM facilities, namely the Brawijaya Street approach, the TMP Street approach, and Parakomando Street approach. While the Angkasa Street approach cannot be applied to ESSM because it does not meet the requirements in the ESSM planning guidelines. The ESSM design on the Brawijaya Street approach uses a 2-lane box type ESSM with an area of 60 m2; on the TMP Street approach using a 2-lane box type ESSM with an area of 60 m2; on the Parakomando Street approach using a 2-lane box type ESSM with an area of 56 m2.

Scholarships are financial aid or funds awarded to individuals or groups to support education, research, or other academic development. There are many types of scholarships such as academic achievement scholarships, non-academic achievement scholarships, financial scholarships, and others. College scholarships are financial aid or funds provided to students to assist them in their pursuit of higher education. Scholarships in tertiary institutions can be full such as smart card scholarships or partial such as free tuition scholarships, and the aim is to encourage wider access to education and help students who are talented but face financial constraints in pursuing their education. At the University of KH. Bahaudin Mudhary Madura for scholarship applicants there are very many, there are hundreds or even nearly thousands of students who register, especially on the smart Indonesian card scholarship and this also requires very fast time and a good level of accuracy in decision making. Therefore, it requires a decision support system. In this study, the deep learning method was applied to a decision support system with a loss of 1.43%, an accuracy rate of 98.57% and a system runtime of 77ms/step.

North Maluku has been the site of microplastic study for some years. The goal of this paper is to revisit the earlier analysis. The intent is to be a quick guide for scholars studying microplastics in North Maluku. Additionally, this article's goal is to quantitatively analyse some of the findings from the research that has been done. The terms "Microplastics in the North Maluku Sea" were entered into the search engines Google Scholar and Science Direct to conduct journal and research searches. Previous studies on microplastics on Mare Island looked at sediments in the island's waters and the levels of microplastics in various kinds of sea cucumbers. A total of 272 microplastic fragments were discovered in sea cucumbers. At the same time, two stations were doing a study on deposits. Microplastics weighing between 17,000 and 37,000 particles/kg of dry sediment were discovered at the first station in Maregam. 13,839-30,666 particles/kg of silt were discovered in Marekofo. According to research conducted on the island of Ternate, skipjack tuna contains up to 948 microplastic particles that were collected from 16 market fish samples. According to studies on other fish species like Epinephelus Fuscogutattus, E. coioides, and E. Suillus, the digestive tract of fish contains 594 microplastic particles.

This study aims to determine the effect of variations in flow rate and the louvered strip inclination angle on heat transfer in a double-pipe heat exchanger and the impact of variations in flow rate and inclination angle of the louvered strip on the inner tube pressure drop in a double-pipe heat exchanger. Three pieces of louvered strips at 50 mm, 70 mm, 90 mm are inserted into the inner tube of the heat exchanger with a constant tilt angle of 25°. Cold and hot water are used at a constant value where the cold-water flow rate is 600 liters/hour and V = 900 liters/hour, while the hot water flow rate is 1200 liters/hour. The inlet and outlet temperatures of both hot and cold water are measured, and the heat transfer characteristics of the heat exchanger are calculated as a result of the pressure drop that occurs in the inner tube due to the difference in height on the U-tube manometer used.

The design of taperless blades using the SG6043 Airfoil with different blade quantities through BEM simulation method is expected to serve as a reference for determining the design that yields the best operational efficiency. Simulation results show that the highest Cp value for the Taperless blade design is achieved with a variation of 3 wind turbine blades, resulting in a Cp value of 0.45 in the BEM simulation. The highest Cp value for the Taperless blade design with 4 wind turbine blades is 0.48 in the BEM simulation. Meanwhile, the highest Cp value for the Taperless blade design with 5 wind turbine blades is 0.47 in the BEM simulation. For low TSR values within the range of 1-4, turbines with 5 blades perform the best among various blade quantity variations, resulting in the highest Cp value. On the other hand, for high TSR values within the range of 5-10, turbines with the fewest blades, specifically 3 blades, achieve the highest Cp value.

Algorithm and Data Structure is a basic course in Informatics Study Program, at Khairun University. This subject needs to be mastered because it becomes the foundation that can support the learning process in the future. However, from the results of a survey conducted, as many as 40% of students felt bored with the teaching methods used by Algorithm and Data Structure lecturers in class. In addition, there were also 73.33% of students that even though they paid attention to the material presented in class, they still found it difficult to understand the material. To overcome this problem, new learning media is needed in the classroom, such as games. This study aims to design educational games that teach algorithms and data structures using the Game Development Life Cycle (GDLC) method. The GDLC is a game development method that is widely used to create educational games. The GDLC method has several development stages, namely initiation, pre-production, production, testing, beta, and release. Alpha test results show that all functionality is appropriate. While the results of beta testing show the number 3.43 of the total respondents' answers to the questionnaire related to game evaluation so they are included in the very good criteria.
