Abstract

Central Sulawesi is one of the main producers of Quarry C, which is processed into crushed stone in crushed stone factories (stone crushers). The number of crushed stone factories operating in the area between Palu-Donggala City is around forty units. The production of crushed stone factories apart from 1-2" and 2-3" crushed stone also contains smaller sized stone ash. This rock ash has a much smaller economic value so it is often not utilized and becomes waste at factory sites. Stone ash with the characteristics of a small specific gravity, even lighter than natural sand, has considerable potential to be used as a building material. It just needs research and testing before being used. Because it has a fine gradation and a small specific gravity, its potential can be used to make lightweight bricks, wall rosters and paving blocks. Apart from that, it is still possible to use it as a filler in asphalt concrete mixtures and aggregates for lightweight concrete. The initial tests required in the laboratory are: sieve analysis and compressive strength tests of bricks, paving blocks and rosters. The test results showed that there was an increase in compressive strength values for both bricks, paving blocks and roofs. The compressive strength value of brick with the addition of stone ash complies with SNI requirements and is included in category A, Paving Block is included in category A for road use, as well as roster there is a significant increase in the compressive strength value.

Abstract

Risk is the cause of unexpected conditions that can cause loss, damage, or loss. This is due to the risks contained in construction projects that can affect the productivity and quality of the project. The Central Sulawesi Province 2 School Infrastructure Disaster Management Project, located in Sigi Regency, Central Sulawesi Province, is a project that handles the construction of school infrastructure. This project is also not free from risks that can cause the project not to run as planned and suffer losses. Based on the description above, the researcher is interested in conducting a risk analysis that occurs in the Central Sulawesi Province School Infrastructure Disaster Management Project 2. The methods used in this study are data collection by distributing questionnaires, conducting data analysis, descriptive statistics, reliability tests, risk analysis, risk response and risk control. This research was carried out for 6 months, starting from preparation, implementation, data collection, and monitoring and evaluation. The outputs to be achieved in this study are scientific articles published in research journals and reports on the results of activities.
