Abstract

Community empowerment program to make a village independent is very important. Village independence could be seen from various aspects, and one of which is the aspect of independence in the provision of clean water. Clean water supply activities in Balong Hamlet, Donoharjo Village, Ngaglik Sub- District, Sleman Regency are community empowerment activities in order to make Balong Hamlet independent on the aspect of the ability to provide clean water. This activity began with a survey and data collection of local residents’ water needs, followed by calculation of clean water requirements, design of clean water supply and distribution systems, implementation of piping installation, commissioning tests, economic analysis, and its contribution in making the village independent of clean water. This activity produces a piping system for clean water from the spring to the houses of Balong hamlets with a population of approximately 203 households. On average, each household needs 600 liters/day so it requires 121.8 m3 /day or 3654 m3 /month. The price of standard clean water for the Drinking Water Company (PAM) is Rp1,960.00/m3 , so the hamlet has saved Rp7,161,840.00/month or Rp85,942,080.00/year. Thus, this activity has made Balong Hamlet contribute significantly to the independence of Donoharjo Village.

Abstract

Portland Composite Cement or PCC is an eco-friendly material that has been registered as a green product. In order to support green construction, the use of PCC has begun to be developed, including rigid pavement for road construction in Indonesia. Things that need to be investigated from the use of PCC are the compressive strength and flexural strength behavior for certain rigid pavement concrete qualities and the initial setting time of cement. The use of PCC which is still in the development stage needs to be investigated by substituting it with Ordinary Portland Cement (OPC). In this study, there were 6 variations of substitution, namely 100% OPC, 20% OPC and 80% PCC, 40% OPC and 60% PCC, 60% OPC and 40% PCC, 20% OPC and 80% PCC, and 100% PCC. . The results of the test using the vicat, the higher the proportion of PCC, the lower the normal consistency, so that the less water content is required for the hydration reaction between cement and water to occur. Meanwhile, the higher the proportion of PCC, the higher the initial setting time, so that the cement setting time is slower. In testing the compressive strength of concrete, the higher the proportion of PCC at the age of 28 days, the compressive strength of the concrete tends to decrease. In testing the flexural strength of concrete, the higher the proportion of PCC at the age of 7 days, 14 days and 28 days, the flexural strength of the concrete tends to decrease. Based on the research results, concrete with a higher proportion of OPC has a higher compressive strength and flexural strength than concrete with a higher PPC mixture.
