Abstract

Penduduk di wilayah kabupaten Morowali yang tinggal di pesisir pantai, memiliki pencaharian sebagai nelayan. Hasil pantauan awal bahwa sebagaian besar rumah yang ditinggali tidak layak huni. Oleh karenanya tujuan penelitian adalah untuk mengetahui: (1) jumlah rumah nelayan yang harus direhabilitasi; (2) besarnya biaya rehabilitasi rumah nelayan tidak layak huni. Penelitian menggunakan pendekatan kuantitatif, data didapatkan dengan pengamatan langsung dilapangan yaitu melihat kondisi rumah nelayan. Populasi Rumah Nelayan yang ada di kabupaten Morowali, sampel diambil di Bungku Timur dan Selatan, pada 4 desa. Analisis data dilakukan dengan mengumpulkan hasil survey, serta menghitung biaya rehabilitasi masing2 rumah nelayan. Hasil penelitian, yaitu jumlah rumah Nelayan di Bungku Selatan yang harus direhabilitasi sebanyak 50 % dari total jumlah rumah, sedangkan di wilayah Bungku Timur sebanyak 23% dari total jumlah rumah ; (2) besarnya biaya real cost rehabilitasi rumah dengan rusak berat sebesar Rp 1.685.800/m2 untuk wilayah Bungku Selatan dan Rp. 1.513.925/m2 untuk wilayah Bungku Timur. Sedangkan wilayah Bungku Timur biaya real cost untuk rusak sedang Rp. 744.000/m2 dan rusak ringan Rp. 555.000/m2 . Disarankan bagi pihakpihak yang terlibat dalam perencanaan rumah Nelayan dapat mengambil manfaat sebagai dasar dalam menentukan jumlah biaya bantuan dalam program rumah layak huni.

Abstract

The airport is one of the important infrastructures in the air transportation field that functions to provide aircraft flight services so that there is a need for compatibility between the fleet and its infrastructure, in this case improving the infrastructure of Syukuranan Aminuddin Amir (SAA) Airport. The aim of this study is to analyze the factors that influence the improvement of the infrastructure of SAA Airport. The location of the study was conducted at the SAA Airport, Banggai Regency, Central Sulawesi Province. Data collection was carried out by distributing questionnaires to 120 respondent passengers on airplanes who use the SAA airport. Data analysis using factor analysis methods. The analysis result shows there are 11 factors that affect infrastructure improvement of SAA Airport is socio-economic, airport service quality, operator service quality, flight traffic demand, air transport service demand, air transportation mode selection, airport departure facility (waiting room) and airplane ticket purchase decisions, parking area and waiting room, flight schedule and potential regional commodity yields, service and process baggage handling, and transportation accessibility to the airport.

Abstract

Risk and uncertainty are factors that construction project managers have been increasingly had to deal with. Project completion time is one of the areas where the expected time is often underestimated or shorter than the actual completion time. Monte Carlo simulation is a widely used simulation technique in modeling a process that is difficult to predict due to its random variables. This study provides a practical way to use Monte Carlo simulation to simulate a project using functions available in a spreadsheet application. A project with five activities was simulated 2000 times using minimum, maximum, and expected duration. The mean, mode, and median simulation results were then plugged into their respective precedence diagram networks to compare them. The precedence diagram computations found that mean, mode, and median project completion times were longer than the initially expected completion time. The mean, mode, and median were 50, 53, and 48 days, respectively, which were 8, 11, and 6 days longer, respectively, than the 42 days initially expected. The study showed that the Monte Carlo simulation could assist the project manager in planning a project schedule that deals with risk and uncertainty more realistically.

Abstract

The aim of this research is to identify the main causes and effects of CCO in the construction of the Palu State Islamic University (IAIN) campus II building project for the Faculty of Tarbiyah and Teacher Training and the Faculty of Sharia and Islamic Economics Lecture Building. Tasks included conducting a field survey via a questionnaire and interviews with main parties; project owner, contractors and consultants who are directly related to the project. It was determined that the top three causes of CCO from project owner, contractor and consultant. The contractor has do CCO at the beginning of the project of 70% respondent, while consultant has changed contract order at mid-project implementation of 50% respondents and 70% at the end project implementation from the contractor. The results that are quite important from this study are the discovery of volume estimation errors and changes in work methods. Errors in estimating volumes are caused by the planning consultant's inaccuracy in planning so that there is a significant difference in volume from the initial contract with conditions in the field so that some work items experience an increase or decrease in volume

Abstract

The implementation of Occupational Health and Safety in construction work needs to be considered so that accidents do not occur. Likewise, the survey project for roads, slopes and bridges during the new normal period of the Covid-19 pandemic needs to be reviewed, because there are deficiencies caused by various factors. Therefore, research was carried out to find out the factors that influence the implementation of Occupational Health and Safety during a pandemic and minimize the risk of accidents. This is a quantitative descriptive study, with a population of 94 respondents. Primary data is done by filling out a questionnaire and using photographs, while secondary data is the required project data. Data analysis uses descriptive statistics and Relative Rank Index. The results of the study of the five main factors that influence the implementation of OHS for road, slope and bridge survey projects are: (1) Human factors: work arrangements and the obligation to use PPE as well as strict supervision necessary to protect workers from the risk of accidents RRI value = 0.934; (2) Environmental factors: available first aid facilities RRI value = 0.930; (3) Equipment factor: working equipment used is always in good condition RRI value = 0.915; (4) Environmental factors: there is a room for resting and a kitchen along with drinking water for workers RRI value = 0.911; (5) Equipment factor: use of appropriate according to the type of work RRI value = 0.896. The results of photographic analysis in the field concluded that the implementation of Construction Health and Safety during the New Normal Period of the Central Sulawesi Covid-19 Pandemic was well implemented. But there are still some workers who still neglect personal safety when doing work by not using personal protective equipment on the grounds that they are not used to it.
