Abstract

Pembangkit Listrik Tenaga Uap (PLTU) Kelurahan Rum Kota Tidore Kepulauan merupakan salah satunya dalam rangka mengolah limbah yang dihasilkan dari proses pembakaran batubara. Limbah yang berupa abu itu dimanfaatkan sebagai bahan campuran dalam pembuatan paving block. Dengan pemanfaatan limbah tersebut, diharapkan akan mampu meningkatkan nilai ekonomis bagi masyarakat. Abu sisa pembakaran batubara yang disebut bottom ash (BA) tersebut bisa dimanfaatkan menjadi zat tambahan dalam pembuatan paving block. Masalah yang di angkat terdiri dari dua poin dan tujuan dari penelitian ialah untuk mengetahui pengaruh penambahan Bottom Ash dan pengaruh perendaman perendaman penambahan bottom ash sebagai bahan tambah, metode yang digunakan adalah metode kuantitatif yang dimana menggunakan tiga jenis variabel yaitu variabel kontrol, terikat dan bebas. Hasil dari penelitian yang menggunakan mutu K-150 dari lima variasi 0%, 5%, 10% 20%, dan 30% dengan waktu perendaman 28 hari tidak masuk spesifikasi. Dapat disimpulkan bahwa hal tersebut tidak dinyatakan gagal akan tetapi dapat di kategorikan ke dalam mutu klas-C.

Abstract

Brick is a building material component used for walls and is made simply from a mixture of Portland cement, sand and water with or without additives. In addition, the manufacture of brick also uses fly ash to improve the quality of the brick. This research was conducted at the Civil Engineering Laboratory of the University of Muhammadiyah North Maluku, the research period was 3 months from November 2024 - January 2025. The data obtained in the field and from the results of the literature are primary and secondary data as follows: 1. Primary data: Field observation data, Interview data, Sampling, Documentation data. Secondary data is data obtained indirectly at the research location which can be through raw data or references obtained from journals or supporting documents related to the research in question. The addition of 10% fly ash has a compressive strength value at the age of 21 days of concrete of 0.35 Mpa and 28 days of 0.36 Mpa. The addition of 15% fly ash has a compressive strength value at the age of 21 days of concrete of 0.29 Mpa and 28 days of 0.28 Mpa. The addition of 20% fly ash has a compressive strength value at the age of 21 days of concrete of 0.27 Mpa and 28 days of 0.21 Mpa. The results of the research conducted showed that the addition of fly ash had no effect on the manufacture of concrete blocks, because the more fly ash used, the smaller the resulting compressive strength so that it did not meet the compressive strength of concrete with K-175 quality. The addition of fly ash with a percentage of 10%, 15% and 20% did not affect the compressive strength of K-175 concrete because the average compressive strength produced at a percentage of 10%, 15% and 20% did not meet the planned compressive strength of 14.50 Mpa.

Abstract

The results of time and cost optimization in this studyusing the alternative of adding working hours resulted in a total completion time of 182days, which is 14 (7.14%) days faster than the normal time of 196 days, with a total project cost ofRp. 1,767,600,000.00, resulting in a cost efficiency of Rp. 232,559,067.27(12.62%). Meanwhile, using the alternative of adding manpower resulted in a totalcompletion time of 179 days, which is 17 (8.67%) days faster than the normal time witha total project cost of IDR 1,767,600,000.00, achieving a cost efficiency ofRp.7,870,582.09 (0.44%). Therefore, time and cost efficiency with the addition ofworking hours is more economical. The implications of this research provide recommendations for project managersin making decisions to accelerate work so that it is efficient in terms of time and cost.

Abstract

This study analyzes the Budget Plan (RAB) calculations for farm road construction in Gurabati Village by comparing flexible pavement and rigid pavement. The methods used include work volume calculations and unit price analysis (AHSP) using Microsoft Excel. The results indicate that the construction cost of flexible pavement is Rp 1,340,350,000, while that of rigid pavement is Rp 1,891,450,000. Based on the analysis of construction costs and long-term maintenance, flexible pavement is more economical to implement. This research can serve as a reference for efficient and tailored farm road construction planning.
