Abstract

Until now, bauxite waste (bauxite tailings) has not been utilized in its entirety, causing an increase in the amount of waste in the bauxite producing areas. The percentage between the bauxite produced and the amount of waste produced is 50%: 50%. This research was conducted to see whether or not the use of liquid waste (tailings bauxite) is appropriate as a place for fine aggregate in the manufacture of concrete. This study used an experimental method with the replacement of the concrete mixture, namely sand with bauxite waste (bauxite tailings) with the proportion of bauxite waste (bauxite tailings) of 2.5%, 5%, and 7.5%. The tests carried out were compressive strength testing, split tensile strength testing, and modulus of elasticity. The results of the test for the highest compressive strength average age of 7 days were found in normal concrete with an average compressive strength of 21.58 MPa. The average compressive strength of 28 days was 7.5% bauxite waste concrete with an average compressive strength of 32.07 MPa. The tensile strength of 7 days was in bauxite waste concrete at 7.5% with a split tensile strength of 2.90 Mpa. The tensile strength of 28 days was in bauxite waste concrete 7.5% with a split tensile strength of 3.26 Mpa. The highest average modulus of elasticity is found in 7.5% bauxite waste concrete with a yield of 26607.03 Mpa, Keywords: Bauxite Waste (Tailing Bauxite), Compressive Strength, Modulus of Elasticity, Split Tensile Strength

Abstract

Senior High School (abbreviated SMA) is a secondary level of formal education in Indonesia after graduating from Junior High School (or its equivalent). High school is taken within 3 years, starting from grade 10 to grade 12. The school that will be studied by the author has several problems that occur, therefore the author is interested in conducting research on facilities and infrastructure in the school. Therefore, the author submitted a questionnaire in order to find out what problems occurred in the school. The purpose of this study is that students are able to analyze the facilities and infrastructure of the Pontianak Mujahidin High School, able to overcome the problems that occur in the environment. The methods used in solving this problem are qualitative methods and quantitative methods. The qualitative method is subjective in nature, the research interacts directly with the object being studied. Meanwhile, quantitative methods are objective, independent research is what is being studied. Facilities and infrastructure problems that occur include the parking area which is enlarged by 33% from the initial area and the elevation of the parking area. The second is the widening of the dimensions of the enlarged drainage channel in order to prevent flooding. Finally, by increasing the dimensions of the classroom lighting so that the classroom lighting is sufficient.

Abstract

SMKN 4 SPP Singkawang is one of the vocational schools that provides education with a focus on agriculture and agribusiness. The purpose of providing education at this school is to produce graduates who are skilled in agriculture. One of the important skills to have in agriculture is topographic surveying. For this reason, students at school are expected to have these skills. These skills can later be used to support various activities in agriculture, such as irrigation planning and determining plant types based on topographic conditions. Topographic surveys can be carried out effectively and efficiently using optical tools such as auto levels. Based on this, Community Service (PKM) activities in the form of auto level training were carried out by students at SMKN 4 SPP Singkawang. The purpose of this training is for students to be able to use auto levels in mapping land contours for agricultural and agribusiness purposes. The training began by providing an explanation of the optical tools that would be used for the survey. The next stage is for students to practice using the optical tools accompanied by the Community Service (PKM) team. The result of this training is that students are able to understand and practice measuring land contours using auto levels. Finally, this training is expected to improve the skills of students of SMKN 4 SPP Singkawang, which will later be able to support various activities in the fields of agriculture and agribusiness, such as irrigation planning, determining plant types, and so on.

Abstract

Rapid developments in the construction era are shown by using the latest technology to improve efficiency and effectiveness in project implementation. One of the technologies widely used by construction experts today is Building Information Modeling (BIM). Building Information Modeling (BIM) is a digital-based concept that integrates 3D modeling and stores important information in the design, construction, and maintenance processes. Given the high demand for workers who are competent in BIM, there is a necessity for coaching or training on BIM applications to ensure that the developed workforce can fulfill the job market requirements. The purpose of this Community Service was to train students of SMK N 8 Pontianak with a concentration of expertise in Building Information and Modeling Design so that these students can better understand the concept of BIM. This training used AutoCAD and SketchUp software as tools for basic levels from 2D to 3D. The training results indicated that 74.18% of students at SMKN 8 Pontianak comprehended the concept of BIM, which they were previously unaware of, compared to a 28.64% percentage prior to the training. In addition, the ability of SMKN 8 Pontianak students to apply AutoCAD and SketchUp software has increased, as evidenced by the results of the images before and after the training. These results are anticipated to empower SMKN 8 Pontianak students to utilize their skills proficiently in the job market.

Abstract

The number of intersections with adjacent intersections in Pontianak City raises its own problems, one of which is the signalized intersection on Jalan KH. Ahmad Dahlan Pontianak. The short - term strategy to overcome these problems is traffic management and engineering to improve traffic flow based on field condition evaluation . Data collection was carried out by means of direct surveys at both intersections. The data obtained is used to obtain the existing conditions which will be a reference in planning a new cycle time by taking into account the coordination theory. Meanwhile, in calculating to get the best performance at each intersection, it is done using the MKJI approach. The best performance at each intersection is then coordinated using the green time between intersections. The results of the analysis of the performance of the existing conditions show that the degree of saturation is DS = 0.86 for signalized intersection 4 and DS = 0.68 for signalized intersection 3 which are not too different from what MKJI requires, DS = 0.75 , but it is not comfortable and safe to go through. From the queue length (QL) at the four intersection of 288 meters > the distance between the intersections which is 200 meters apart, and also from the delay time (DQ) of 66.03 seconds > from the green cycle time of 25 seconds, After knowing the performance of the existing intersection, then create a new cycle time planning for both intersections. The new cycle time with the best performance will be used to coordinate the two intersections. Selection of the best cycle time by comparing the values ​​of the degree of saturation (DS), the length of the queue (QL), and the delay (Delay) from several alternatives that were carried out. From the results of the study, a new cycle time of 95 seconds was obtained. The offset time used is 36 seconds, and the bandwidth from East to West and from West to East is 16 seconds. With the new cycle time the performance values ​​of the two intersections get better because the average delay and queue length decrease, for intersection 4 (DS = 0.76; QL = 136 m; DQ = 67 seconds) and intersection 3 (DS = 0, 67; QL = 94.5 m ; DQ = 65.37 seconds),
