Abstract

The need for adequate parking space is one of the main challenges for the Muhammadiyah University Magelang Campus along with the increasing number of student and staff vehicles. The current parking facilities are not able to accommodate the volume of vehicles, especially on days with high campus activity. This condition demands an effective parking management solution to optimize the use of available land and meet future parking needs. This research aims to analyze the management of parking space requirements on the Muhammadiyah University Magelang Campus as an alternative in handling parking facilities. This study uses systematic research methods, starting from reviewing previous research, problem identification, surveys, data collection from written references, to data processing and drawing conclusions. The analysis results show that the need for vehicle parking spaces on campus is greatest on Wednesdays, with a total requirement of 1,293 SRP, while the currently available parking capacity is only 839 SRP. This indicates that the existing parking capacity is not sufficient for the needs of vehicles parked on campus. Projections for the next five years show the need for parking spaces of 1,600 SRP in 2025, 1,468 SRP in 2026, 1,462 SRP in 2027, 1,383 SRP in 2028, and 1,348 SRP in 2029. Based on these data, it can be concluded that this will happen parking shortage on campus in the next five years. As a solution, this research recommends increasing parking capacity through the construction of new parking lots by increasing the number of parking floors on campus. In particular, it is planned to build a multi-storey parking building for motorbikes and additional parking spaces for cars with a more effective and efficient 60° angle parking pattern.

Abstract

Proyek konstruksi bangunan gedung sering kali mengalami masalah yang terjadi pada proses pelaksanaan terutama menyangkut perselisihan antara rencana dengan realisasi, masalah tersebut menimbulkan terjadinya perubahan pada pekerjaan yang biasa disebut Contract Change Order (CCO). Perubahan kontrak pada proyek bangunan gedung sering terjadi karena kesalahan estimasi volume dan penambahan atau pengurangan item pekerjaan yang disebabkan oleh perencanaan yang kurang baik. Penelitian ini dilakukan untuk mengetahui besar pengaruhnya terhadap kinerja biaya, mutu dan waktu. Penelitian ini menggunakan data dari responden dari kontraktor dengan cara memberikan kuesioner untuk penilaian besar pengaruh CCO dengan menggunakan metode analisa rank dan korelasi. Hasil dari penelitian memberikan kesimpulan bahwa yang paling berpengaruh adalah terhadap kinerja mutu, lalu yang kedua terhadap kinerja biaya dan yang ketiga terhadap kinerja waktu. Hasil analisa korelasi memberikan hasil semakin bertambahnya nilai CCO maka akan semakin memperburuk kinerja mutu, semakin bertambahnya nilai CCO maka kinerja biaya juga akan buruk atau biaya mengalami peningkatan, tetapi hasil dari korelasi pengaruh terhadap waktu hasilnya kecil atau tidak signifikan karena waktu dapat dinegosiasikan kepada pemilik proyek untuk menyelesaikan pekerjaan dengan waktu yang relatif cukup.

Abstract

Road drainage channels as complementary road structures in Magelang City in the form of U-shaped concrete channels made using the Factory Precast method and the In Situ method.This study analyzes the work of U-shaped concrete channels using the Factory Precast method and carried out in situ by calculating the Unit Price Analysis of the Work. Price Analysis is calculated based on the Circular Letter of Director General of Construction Development No:68 / SE / Dk / 2024 concerning Procedures for Compiling Cost Estimates for Construction Work in the Public Works and Public Housing Sector.The Unit Price Analysis of Work also refers to the Circular Letter of the Director General of Highways, Ministry of Public Works and Public Housing, Number 16.1/SE/Db/2020 concerning the General Specifications of Highways 2018 for Road and Bridge Construction Works (Revision 2), which stipulates that payment for U-shaped channel work must be paid according to the contract price per unit of measurement for the payment item, where the price and payment must be full compensation.The study also calculated the level of risk for problems that could arise during the implementation of precast U-shaped concrete channel work from manufacturers and in situ.Research data was taken through a survey of material prices and workers' wages, as well as filling out questionnaires by taking samples of respondents from Supervising Consultants and Field Supervisors.The research results show that the price per meter of length of U-shaped concrete channel work with full compensation payment using the In Situ method is cheaper than the Factory Precast method. In the In Situ method, the unit price per meter of length for U-shaped concrete channel work Size 40/60 is Rp. 1,129,889.83 and for size 50/70 is Rp. 1,325,344.70. Meanwhile, in the Precast Factory method, the unit price per meter length for size 40/60 is Rp. 1,443,028.48 and the unit price per meter length for size 50/70 is Rp. 1,617,195.15Based on the research results, although In situ is cheaper than Pre Cast, it has a higher level of risk for potential problems that can arise, namely the quality of the concrete is not in accordance with the specifications, the dimensions of the channels are not in accordance, the work time is long, the finishing of the work is not neat, and the concrete reinforcement steel is not in accordance with the specifications so that stricter supervision is needed so that the results of the construction work are good.

Bulus II, Candibinangun, Pakem District, Sleman Regency, Special Region of Yogyakarta 55582. After collecting all the necessary data, it was organized and analyzed using various calculations according to standard formulas. These calculations included NPV (Net Present Value), IRR (Internal Rate of Return), BCR (Benefit Cost Ratio), PP (Payback Period), ROI (Return on Investment), and ROE (Return on Equity) to determine the project's feasibility. The analysis results yielded an NPV (Net Present Value) of 207.88 billion Rupiah. The IRR (Internal Rate of Return) was 30.11%, which is higher than the MARR (Minimum Attractive Rate of Return) of 15%. The BCR (Benefit Cost Ratio) was 1.2584, indicating that the ratio of income to expenditure is greater than 1, making it viable. The Payback Period was calculated to be 1.017 years, or approximately 12.2 months, or 366 days, meaning investors can expect to recover their money in that timeframe. The Return on Investment was 15.32%, and the Return on Equity was 39.65%. From these calculations, we can conclude that the Upala Villa Kedaton Jogja Eco Wisata housing project is a viable investment. This conclusion is based on the positive NPV of 207.88 billion Rupiah, an IRR of 30.11% which is higher than the initial MARR of 15%, a Benefit Cost Ratio of more than 1 at 1.2584, a Return on Investment of 15.32%, and a Return on Equity of 39.65%.

Abstract

In construction procurement in Indonesia there are still deviations in the tender process. The deviation is caused by an opportunity during the construction bidding process. The service providers are mutually looking for opportunities to seek personal or group benefits or from the working group that makes these deviations. This causes state losses due to deviations in the construction bidding process. This research was conducted by collecting data from institutions that have the authority to decide whether or not deviations occur in the auction process. The institution authorized to decide whether or not a deviation occurs is the Commission for the Supervision of Business Competition of the Republic of Indonesia (KPPU RI). This study uses a questionnaire to find out how much the causes and impacts on state losses are caused by deviations in the auction process and uses the Probability and Impact Matrix method to determine the level of implication values of the causes and impacts of deviations in each case using a case base analysis approach. The results obtained based on the decision are as many as 12 types of deviation based on the case decision. The impact of deviations that occur in construction procurement is material and immaterial losses. The causes of deviation in construction procurement are caused by four factors, namely the factor of wanting to obtain personal or group benefits, opportunities, pressure and business climate. The most contributing factor to the occurrence of deviation is the combined conspiracy and vertical conspiracy resulting in a value of 11.38%.

Abstract

Magelang City faces the challenge of limited land availability, with a total area of only 18.58 km2 and a high population density. Consequently, telecommunications infrastructure development requires a precise strategy. This study aims to analyze the business model and investment feasibility of Pole and Greenfield type telecommunication towers in Magelang City. Using a descriptive quantitative approach, this research processes secondary data from PT Dayamitra Telekomunikasi Indonesia by applying feasibility analysis based on Life Cycle Costing (LCC), Net Present Value (NPV), Internal Rate of Return (IRR), Break-Even Point (BEP), Payback Period (PP), and Benefit-Cost Ratio (BCR). The results indicate significant differences in cost structures; Pole towers proved to be more efficient, requiring an initial capital outlay of only 28.8% of the total capital required for Greenfield towers. Greenfield towers generated an NPV of Rp13.07 billion with an IRR of 20%, while Pole towers generated an NPV of Rp2.46 billion with a higher IRR of 23%. Pole towers have proven to offer a faster return on investment and better operational cost efficiency, making them the most strategic option to support network densification and the implementation of 5G technology in urban areas with spatial constraints like Magelang City.

Abstract

Idealnya pasokan dan permintaan dari suatu barang atau jasa harus memenuhi prinsip keseimbangan, termasuk pengadaan rumah layak huni untuk masyarakat luas. Pengadaan rumah layak huni untuk masyarakat umum di Indonesia dilakukan oleh Pemerintah, pengembang, program Corporate Social Responsibility dan masyarakat.      Saat ini, di tengah masyarakat terjadi kekurangan (backlog) rumah layak huni yang sangat besar, oleh karena itu supply yang ada diharapkan dapat mengurangi atau membereskan backlog tersebut. Tujuan dari tulisan ini adalah melakukan perhitungan kebutuhan dan pengadaan dalam time series sehingga tercapai keseimbangan supply-demand dari rumah layak huni. Metode yang digunakan dalam perhitungan ini adalah: a. menyusun konsep dan variabel perhitungan kebutuhan rumah layak huni dan perhitungan pengadaan rumah layak huni berdasarkan potensi produksi yang realistis, b. mencari data yang relevan yang tersedia secara online dan  valid dari publisher yang terpercaya  untuk perhitungan-perhitungan tersebut, dan c. melakukan eksperimen sehingga terjadi keseimbangan supply-demand pada waktu yang realistis berdasarkan besarnya nilai backlog dan kapasitas bangun yang ada. Hasil yang didapat dari penelitian ini adalah bahwa keseimbangan antara supply dan demand akan terjadi pada akhir tahun 2048 jika terjadi supply sekitar 2,7 juta unit rumah layak huni per tahun dimulai tahun 2023.

Abstract

This study aims to analyze the importance of applying professional ethics in civil engineering for decision-making related to safety, health, and environmental risks (K3L). This is crucial because, like other professions, civil engineering is a complex and intricate field that requires not only engineers with good technical skills but also sound decision-making abilities. The decision-making process significantly impacts the execution of infrastructure projects. Professional ethics serve as a guideline for engineers in making decisions that consider K3L. The issue is that decision-making is not solely based on technical skills but also on other soft skills such as emotional control. This study found that emotional intelligence (EQ) can influence the decision-making process of engineers. The higher an engineer's emotional intelligence, the better their decision-making regarding K3L risks. This is also related to engineers adhering to the professional code of ethics. Furthermore, good decision-making processes are expected to promote sustainable infrastructure development.
