Abstract

Seiring dengan berkembangnya pengolahan sampah, tempat pembuangan akhir (TPA) cenderung memicu berbagai dampak lingkungan. Untuk meminimalkan dampak sampah TPA terhadap pencemaran lingkungan sekitarnya, sampah tersebut ditutupi oleh bahan untuk mengisolasinya dari lingkungan. Oleh karena itu dibutuhkannya pemanfaatan dengan menggunakan lumpur water treatment guna menghambat dan mengurangi dampak lindi sehingga juga mendapatkan nilai koefisien permeabilitas penutup TPA Sementara. Metode pembuatan penutup TPA sementara menggunakan material lumpur IPAM Perumda Tirta Manuntung Km.8 Balikpapan yang diperkuat dengan MICP (Microbially Induced Calcite Precipitation) dan juga memanfaatkan bakteri bacillus subtilis untuk memperkecil nilai permeabilitas tanah sehingga lapisan penutup yang dihasilkan dapat memperkecil kemungkinan kerusakan lingkungan dan pencemaran air tanah oleh air lindi dari pembusukan sampah. Setelah dilakukan penelitian dapat disimpulkan bahwa Permeabilitas tanah tanpa campuran menunjukkan nilai permeabilitas sebesar 5,04×10-4 cm/s dimana permeabilitas limbah lumpur PDAM dapat memenuhi kriteria sebagai penutup TPA sementara, adapun batas spesifikasi permeabilitas antara 10-4 sampai 10-5 cm/dtk. Setelah dilakukan penambahan dengan metode MICP diperoleh permeabilitas terdapat pada sampel larutan bakteri 16 % dengan kultur 2 hari pada masa pemeraman 7 hari yaitu sebesar 4,19x10-4 cm/s dan permeabilitas terendah yang didapatkan adalah 1,49x10-4 cm/s dengan konsentrasi larutan bakteri 16 % kultur 3 hari pada masa pemeraman 28 hari.

Abstract

Manggarai Station is planned to be central of public transportation in Jakarta. Commuter line or known as KRL is one of the modes offered at the station and has served trips and become a favorite mode of Jabodetabek commuters. The planning requires a switchover transition, which impacts Manggarai Station in the form of changes in routes and infrastructure. This also has an impact on commuter travel behavior. This study aims to identify variables that relate and affect commuter travel behavior towards changes at Manggarai Station. Methods were conducted with chi-square and multinomial logit analysis on a sample of 400 commuters through questionnaire data. The results show that the factors associated with changes in passenger behavior are marital status, education, income, location of residence, number of cars and motorbike owned, origin station, alternative modes used, destination line, transit frequency, travel frequency, waiting time, overall travel time, KRL travel time, mode used and changes in other passenger behavior. In addition, factors that have a significant effect of 34.6% on changes in commuter travel behavior are the location of residence (Bogor City), origin station (Cilebut Station and Bojong Gede Station), the mode used (public transportation), KRL travel time (100-199 minutes) and awareness of changes in other passenger behavior. Meanwhile, the other 65.4% is influenced by independent variables outside the study.

Abstract

Indihiang Terminal, a Type A terminal located in Tasikmalaya Regency and was built in 2005 under the management of the Ministry of Transportation and Transportation. This terminal found a fundamental problem: namely the lack of passengers, this has been going on for a long time. Some passengers prefer to depart and get off at bus pools or public roads rather than at the terminal. Research objective to Evaluate terminal performance. Research method: using descriptive quantitative method with Importance Performance Analysis (IPA) and Simple Additive Weighting (SAW) methods. Research sample, The sample used in this study was 64 people. Research results Based on the IPA method, 14 facilities need to be prioritized because, above the iso rating line. Conclusion, Location, accessibility, and onward transportation to or from the Indihiang terminal in Tasikmalaya City are things that need to be improved again and the bus operational system in terms of boarding and dropping passengers needs to be rearranged so that buses pick up and drop off passengers at the terminal.

Abstract

The Solo-Semarang dual railway line project is considered to have a high risk of danger because it is located very close to level crossings and becomes a meeting between seven roads so that it can endanger residents and the environment as well as project workers who are in the project area. The purpose of this study is to conduct a risk assessment using the Fuzzy Failure Mode And Effect Analysis (FMEA) method of hazards or potential incidents in railroad bridge erection work. The Fuzzy FMEA method is used to identify work accident risks and determine risk mitigation priorities based on the highest Fuzzy RPN (Risk Priority Number) value. The results of the research conducted from March - April 2023 obtained 14 (fourteen) risks obtained from observations and Job Safety Analysis documents. Based on the processing results, the highest Fuzzy RPN value was obtained in the erection work of 500 (five hundred) for the risk of machine damage. This value is in the high category so that risk mitigation actions are needed to prevent and reduce the impact of risks.

Abstract

A highly productive workforce is essential for a construction project to be successful because worker productivity has a significant impact on the final outcome, especially in the construction industry. Wall plastering is an example of a profession that requires hard work. The aim of this research is to calculate the productivity coefficient for plastering work and compare it with the 2022 Indonesian National Standard Work Unit Price Analysis (AHSP SNI) in order to measure the efficiency of wall plastering at work sites. This research was carried out by collecting primary data regarding the efficiency of plastering work at the Basic Laboratory Building at Samudra University through field observations and interviews. Productivity factor analysis of wall plastering work shows an average of 47.61 m2 per day for foremen and head craftsmen, 13.88 m2 per day for craftsmen, and 22.72 m2 per day for assistant craftsmen. Apart from that, the foreman and head craftsman produce 66.66 m2 per day, the craftsman produces 6.66 m2 per day, and the assistant craftsman produces 3.33 m2 per day according to SNI AHSP. Thus, the difference in percentages obtained for the foreman and head craftsman respectively is 28.57%, for the craftsman 52.01%, and for the assistant craftsman 85.34%. Key words:Builder Productivity, Wall Plastering, Building Projects.
