The need for housing continues to increase as the number of inhabitants increases. Housing development as one of the efforts to meet the needs of the community for residential houses. The Andalusian Griya Giri housing estate in Gresik Regency was built with a type. However, with the vast area in Gresik Regency and the fierce competition of housing developers who offer housing in a higher segment and at prices that do not differ much, it can be concluded that this housing is a waste of costs in development. Therefore, a way is needed to overcome this problem, namely by applying Value Engineering. This study aims to analyze the optimization of the calculation of the cost budget plan without reducing the quality and function of the building with the Value Engineering method. The analysis technique in Value Engineering of this study uses a comparative method with cost analysis. This method compares the profit price of the landcape design before it is redesigned with the design that has been redesigned, namely changing the house plan, appearance and number of house compositions / site plans so that maximum profit is obtained. This analysis uses the stages of the Value Engineering plan, namely the information stage, stage, creative, analysis stage, recommendation stage and presentation stage. Based on the results of the Value Engineering analysis at the Griya Giri Andalusian Housing Project in Gresik district, the most profitable design alternative was to use Design C with the change of type 38/72 housing units to 36 units. The profit price after redesigning from the original design, the production price of the type 38 house is Rp. 122.2 40. 00,000 becomes Rp. 9 0.728.514. The amount of profit increased generated after the redesign of the original design and the change in the number of house compositions / site plans was carried out amounting to Rp 7,864.960. 000 becomes Rp. 9,981,773,496.

Abstract

Pada tahun 2019, pemerintah pusat membuat DED Revitalisasi Terminal Tipe A Arjosari Malang. Adapun Rencana Anggaran Biaya (RAB) yang dibutuhkan untuk revitalisasi secara keseluruhan adalah Rp. 80 Milyar. Kemudian berdasarkan hasil rapat pembahasan pagu kebutuhan TA 2024 pada tanggal 30 Januari 2023 bertempat di Jakarta, RAB untuk revitalisasi Terminal Tipe A Arjosari Malang terlalu besar dan perlu diefisiensikan lagi. Salah satu item pekerjaan yang masih bisa diefisiensikan biayanya adalah item pekerjaan arsitektur. Ada beberapa faktor yang menyebabkan biaya pekerjaan arsitektur menjadi besar, antara lain bahan dan teknologi. Penggunaan bahan yang mahal dapat meningkatkan biaya proyek arsitektur. Berkaitan dengan hal tersebut di atas, maka digunakan rekayasa nilai atau value engineering dengan tujuan untuk mengefisiensikan biaya serta mencari alternatif alternatif atau ide-ide yang bertujuan untuk menghasilkan biaya yang lebih baik atau lebih rendah dari harga yang telah direncanakan sebelumnya. Hasil value engineering pada pekerjaan arsitektur menghasilkan penghematan sebesar sebesar Rp.1.718.085.568 atau 8% dari biaya awal proyek pekerjaan arsitektur.

Abstract

Flooding in front of the Sidoarjo Class 1A Religious Court Office road happens frequently during the rainy season. It disrupts traffic and damages the roads. Flooding is caused by the condition of the drainage channels, which are not performing efficiently due to sediment barriers such as garbage, and some channels appear to be damaged. The existing channels can no longer accommodate the water discharge caused by the rain, thus water overflows from the drainage channels, flooding the main road. These conditions show the importance of handling drainage problems. One of the ways that can be taken is to evaluate the capacity of existing drainage channels.In this study, the evaluation of drainage channel capacity was carried out using the Hydrological and Hydraulics Analysis method. The purpose of this study was to determine the amount of drainage channel storage capacity required to resolve flooding. The results of this study showed that the design rainfall obtained based on the Log Pearson Type III method was 116.583 mm/day with a 5-year return period. The design flood discharge in channel T1 was 0.717 m3/second, while the capacity of the existing tertiary channel T1 = 0.009 m3/second, so the discharge that overflows from the existing channel T1 was 0.708 m3/second. The capacity of the secondary channel S1 was 2.604 m3 /second, whereas the capacity of the primary channel P1 was 43.043 m3 /second. The capacity of the T1 channel was known to be unable to accommodate the design flood discharge. Therefore, alternative treatments were required to ensure that the T1 channel could accommodate the designed flood discharge.

Abstract

The implementation of the Situbondo – Ketapang – Banyuwangi Road and Bridge Preservation Project experienced changes in the area being worked on, requiring additional design. Issues arose when the overlay asphalt mix work was halted to await test results for Aspal Modiv PG – 70 from the Pusjatan Bandung Road Materials Laboratory, causing a delay in the 40th week by -0.813%. Delays primarily occurred in the AC - WC and AC - BC asphalt work, affecting project performance. A cost and time analysis was necessary to address this issue. The Earned Value Method (EVM) was used to determine the project's duration and cost until initial handover. The study results indicated that the project cost performance with a CPI > 1 was good, but an SPI of 0.983 < 1 indicated delays. The estimated final project cost is Rp 112,439,121,070.91, with an estimated completion time of 453 days, 3 days longer than the planned schedule.

Abstract

Construction project management prioritizes the achievement of three main objectives: cost, quality, and time. This study evaluates a road widening project in Mojokerto Regency with a target completion time of 150 days. To prevent delays and cost overruns, researchers used the Earned Value method to identify early warnings regarding project performance. This method integrates time and cost values through measurements of Cost Variance (CV), Schedule Variance (SV), Cost Performance Index (CPI), Schedule Performance Index (SPI), Estimated at Completion (EAC), and Estimated Schedule at Completion (EAC). The research findings show that additional costs required (ETC) reached Rp 3,276,704,110.14, with additional time (ETS) up to week 12 being 87 days. The change in project costs (EAC) reached Rp 3,961,767,811.01 from the contract cost, while the project completion time (EAS) was 171 days. The analysis indicates that the construction service provider has implemented an efficient implementation method with consistent supervision, ensuring the smooth progress of the project.
