Abstract

In project development planning is a measure of the success of a project, which can determine the allocation of funds, time and quality to be obtained. This planning is combined with the use of special planning software, namely Microsoft Project 2021, which with this software can help make rescheduling easy and can track developments in the field. The data was analyzed using the Precedent Diagram Method (PDM) using the Microsoft Project 2021 application and the resulting plan is a network of all project work scopes. The results of the scheduling analysis of the Air Santri Urban Slum Quality Improvement Project, Banjar Regency, using the Microsoft Project 2021 application is that the project was carried out for 335 days obtained based on the scope of work with the largest duration of this project, namely 12 months 25 days starting on May 21 2021 ending on June 15, 2022. The total duration for each scope of work is Public Open Space (RTP) for 331 days, Retaining Walls (DPT) for 335 days, Roads for 139 days, Pier for 96 days, Waste Management Area (TPS) 170 days duration, SPAL DT 57 days duration and Clean water installation 201 days duration. Keywords: Microsoft Project 2021, Precedence Diagram Method (PDM), scheduling.

Abstract

This population growth has an impact on the economy and the community's need for housing. This is an opportunity for developers to open residential areas. Developers need to pay attention to the purchasing power of the people so that housing is built optimally and developers can generate maximum profits. Research was conducted to find the optimal combination of the number of houses for each type. These limitations include limits on production costs, limits on land area, limits on construction time, and limits on people's purchasing power for each type of house. This study uses the QM for Windows program to process the data analysis. The primary data used was obtained from 50 questionnaires distributed and the secondary data was obtained based on the developer's information. The optimization results obtained are 45 units of subsidized type 36 houses, 51 units of non-subsidized type 36 houses, 39 units of type 45 houses, and 15 units of Type 50 houses. The developer generates a maximum profit of IDR 8,534,000,000.00 with a total of 150 houses built. Sensitivity analysis was also carried out on the purchasing power of the people. The result is that people's purchasing power has a major influence on the combination of the number of houses of each type that are built and the benefits that the developer gets.

Abstract

To increase rice production in Tanah Laut Regency, one of the programs implemented by the Tanah Laut Regency Government is the development of swamp irrigation areas in Sabuhur Village. Sabuhur Village has a large swamp area, which has great potential to be developed as agricultural land. However, the success of this development is highly dependent on the suitability of the soil for use as agricultural land. Therefore, testing the physical and chemical characteristics of the soil is a crucial first step to identify the potential and constraints that may occur. The method used is field sampling and laboratory testing. Based on the test results, it can be seen that the characteristics of the physical and chemical properties of the soil at the research location. In terms of soil physical properties at the location, it can be known that soil permeability ranges from 1.86-3.64 cm/h (silty clay), bulk density ranges from 1.01-1.46 g/cm3 (most have exceeded critical values for agriculture), particle density ranges from 1.9-2.86 g/cm3 (mineral soil conditions), porosity ranges from 38.83%-63.31% (silty clay), and aggregate stability ranges from 14%-62.8%. As for the chemical properties of the soil, the total Fe content ranges between 112.19-507.47 ppm, pyrite content between 0.004-0.053% (small pyrite content), CEC ranges between 16.15-30.81 me/100gr (moderate to high soil clay content), and moisture content ranges between 4.88%-29.03. Therefore, the sampling location is not a swamp area because it is mostly mineral soil with a small moisture content. The observation location is a permanently submerged wetland environment.
