Abstract

Land work (land clearing) in the Bunda Asri housing development project was carried out to meet the contours of the land so as to reach the planned contours, according to housing project data the volume of excavation work (cut) was 374,758.15 m³ and heap (fill) was 323,320.39 m³. The volume of excavation (cut) and embankment (fill) is divided into five sections of the earthwork area with a duration of work completion of 90 calendar days. Time constraints are the reason for project or work activities to be right on plan. Scheduling in this study uses the precedence diagram method (PDM) and is assisted by Microsoft Project software. A network that has definite dependencies and can be used in projects with overlapping activities between one another's work is called PDM. The results of the research analysis used the PDM method for the construction of Bunda Asri housing, namely 81 calendar days. which is faster than the estimate of the housing developer which lasted 90 calendar days. This happened because the grouping of work with a work breakdown structure and predecessors reduced the duration time and did not precede each other among other works.

Abstract

Online transportation has become an integral part of urban mobility, providing an efficient and convenient alternative for people. This study aims to analyze user preferences between the two main online transportation platforms, namely Gojek and Grab, in the city of Pasuruan. The TOPSIS (Technique For Order of Preference by Similarity to ideal Solution) method is used to identify user preferences in the context of the city. This research was conducted through a survey of a sample of online transportation users in the city of Pasuruan. The data collected includes factors such as price, convenience, performance and security offered by Gojek and Grab. The data is then processed and normalized to obtain the relative weight of each factor based on user preferences in the city of Pasuruan. Next, positive and negative ideal matrices are formed to compare user preferences for platforms. The results of the analysis using the TOPSIS method show a user preference for Gojek of 0,56, while Grab obtains a preference value of 0,43 in the city of Pasuruan. These findings provide insight into the most influential factors in user decision making in choosing between the two platforms in the city of Pasuruan.

Abstract

Erosion is a serious problem in riverbank areas. This is because erosion is the starting point for subsequent natural disasters such as landslides. Based on this understanding, empowerment is needed by installing an Early Warning System, mapping of vulnerable areas and evacuation routes, as well as outreach aimed at increasing the understanding and awareness of residents for mitigation. The early warning system socialization program is carried out with Focus Group Discussions so that it can run interactively. Thus, it is hoped that there will be an increase in public understanding and awareness of natural disasters, as well as an increase in the quality of community empowerment by students in the implementation of applied science.

Abstract

This study explores the use of natural dyes as an environmentally friendly alternative to synthetic dyes for coloring batik fabric. Specifically, the researchers focus on developing natural dyes from a combination of avocado leaves and soursop leaves. The study aims to determine the impact of extraction time and the ratio of avocado and soursop leaves on the color fastness of batik cloth. Experimental methods were employed, with two extraction times (120 and 240 minutes) and three ratios of raw materials (25%:25%, 15%:35%, and 35%:15%) tested. The results of the color fastness test, which assessed washing and rubbing, demonstrated that the mixture of avocado and soursop leaves exhibited good fastness and resistance to rubbing. These findings suggest that the extracted mixture could be used effectively as a natural dye for batik fabric. Overall, this study contributes to the development of eco-friendly alternatives for the dyeing process in batik production.

Abstract

The majority of road construction in Indonesia uses flexible pavement, namely Asphalt Concrete (AC). Therefore, to meet the need for asphalt, Asbuton was carried out. This research aims to determine the effect of Asbuton content, mixing temperature, and compaction temperature on the workability index value. Therefore, research was carried out regarding the workability of the AC-WC mixture with Asbuton B 50/30 The preparation of test objects was carried out using the dry mixing method. The Asbuton content used was 10% and 15% and the mixing temperature was varied, namely 160⁰ C, 170⁰ C, 180⁰ C 190⁰ C, and 200⁰ C and the compaction temperature was 110⁰ C, 120⁰ C, 130⁰ C, 140⁰ C, and 150⁰ C at the level optimum asphalt. Then, the data obtained is processed using a statistical approach. The research results showed that the AC-WC mixture with 10% Asbuton content and varying mixing and compaction temperatures had a workability index value from 2.9890 to 5.7737. Meanwhile, the AC-WC mixture with 15% Asbuton content and varying mixing and compaction temperatures has a workability index value ranging from 3.3252 to 6.9845. This shows that variations in Asbuton content, mixing temperature and compaction temperature influence the workability index value of the AC-WC mixture.

Abstract

Quality control is one of the obstacles experienced by PT. Wahana Kasih Mulia on CV. KKN. Quality control is an important thing that must be done by companies to minimize defective products. To be able to analyze product defects, researchers use the six sigma model, by formulating the Define, Measure, Analyze, Improve, Control (DMAIC) stages. The purpose of this study was to determine the level of quality control using the DMAIC method with the Six Sigma model applied to manufacturing companies. The results showed that from the measurement of the number of Omiland brand baby mattress products in the January-October 2021 period, it was found that defective products came from three main causes of disability. The distribution data of the number of product quality characteristics and company performance are at the sigma level of 3.50 with a DPMO value of 27,082.275. This shows that the company has not been able to meet process quality standards. Based on this research, the recommendations for improvement given are that the company needs to provide periodic training to employees, perform maintenance on machines, apply a clearer and more detailed Standard Operating Procedure (SOP), conduct tighter supervision of newly arrived raw materials and the company needs to place quality control at every stage of the production process.

Abstract

With the increasing era of globalization today, competition in the industrial sector is becoming increasingly fierce and competitive. With the development of modern technology for the better but on the other hand raises problems for the environment. Every business actor who wants to win the competition must pay full attention to the quality of the products or services produced, at a low cost, the right time and quantity, and safe conditions. This study aims to analyze and reduce waste of packaging waste at PT XYZ, a manufacturing company engaged in the manufacture of medicines and vaccines. In the last 7 months, there were 1,906 pcs of defective packaging out of a total of 204,940 pcs used. The defects were caused by mold, misprinted information, faded colors, and lack of glue on the packaging. The methods used in this research are Pareto diagram and fishbone diagram. Pareto diagrams are used to identify dominant product defects, while fishbone diagrams are used to identify the causes of defects. It is expected that the results of this research can help PT XYZ reduce packaging waste and improve the quality of their products. By reducing packaging waste, PT XYZ can also contribute to reducing negative impacts on the environment.
