Abstract

In Bukaka area, Bone Regency, South Sulawesi, Indonesia, a small scale industry of red-bricks with clay as the raw material is exist, which have been operated by the local people in generations for decades. From field observation, a problem was identified related to the quality of the bricks produced, which mostly not fulfilled the quality standards. The purpuse of this community service activiy is to conduct a series of laboratory tests to define and formulate recommendations in order to improve the quality of the raw material and the bricks. Methods of laboratory works performed in this activity include mineralogical analysis (XRD) and chemical analysis (XRF) for clay samples, as well as dimension test, baking test, colour, saline content, absorbtion, compressive strength and sound test for the bricks. The results showed that the clay material composed of feldspar, quartz, kaolinite, and calcite; with high content of iron (Fe2O3 up to 8.85%), thus it is recommended to conduct a decreasing grade of the iron content using magnetic separator method. Dimension of the bricks produced by the local workers were generally far above the quality standard; thus it is recommended to conduct an increasing size of the bricks, particulary in their thickness and width. For the bricks baking, it is recommended to perform an increasing temperature and duration of the baking in order to gain a better quality. Absorbtion of the bricks were also averagely low, 0.5-0.6 gr/dm2/minute, thus it needs to be treated carefully at the time of the raw material mixing. Uncompressed strength test of the bricks resulted average value of 24.47 kg/cm2, which indicated a Class-25 type of the bricks, and having a good quality of sound.

Abstract

The implementation of Occupational Safety and Health (OHS) construction materials mining has not been implemented properly, including at PT Harfia Graha Perkasa. The problem faced is the lack of understanding of the importance of OHS and the potential hazards in the mining work environment both in mining, transportation and processing activities. On the other hand, there is a regulation that every mining activity must have an OHS program and standard, so the main purpose of this community service activity is to provide knowledge and understanding of OHS to mining workers. The method used is an OHS promotion program in the form of information dissemination, identification of potential hazards, and risk control efforts. The level of understanding of workers is measured through pre-test and post-test questionnaires given to 12 respondents. Prior to the initiation of the OHS program, only a total of 30% of all OSH questions were known by the workers, but after the program was carried out it was seen that there was a significant increase in the understanding of mining workers to 90%. The information dissemination program showed very good results where 100% of the information on OHS and 90% of the information on risk control efforts was known by the mine workers. This shows that service activities programs can help initiate the implementation and implementation of OHS in partner companies.

Abstract

The partner of this community service activity is Islamic Boarding Schoo of Tahfidzul Qur'an of Miftahul Jannah Putri in Pamanjengan, Moncongloe, Maros Regency. This boarding school guides 10 students from underprivileged families. The partner's main problem is the difficulty in meeting water needs for daily needs because there is no clean water service available through the network of Regional Drinking Water Companies and limited groundwater production from existing bore wells. Therefore, the boarding school manager and students tries to get ground water by developing the addition of groundwater wells as seen from the results of the pre-test. This boarding school has an area of ​​800 m2 making it possible to develop a better groundwater borehole. However, there are concerns about its success because several well drillings that have been carried out in its vicinity have not succeeded in obtaining water of the quality and quantity as expected. Therefore, this groundwater well development activity is carried out in stages based on a groundwater science approach which includes the stages of surface mapping, geoelectrical measurement, groundwater drilling, well construction and pumping. Drilling was carried out to a depth of 60 meters. The drilled well was pumped at a flow rate of 0.40 liters/second (1,440 liters/hour) and reached steady state at a water table drop of 1.60 meters. Thus, this community service activity was declared successful in accordance with the output target with the availability of groundwater production wells of good quality and sufficient quantity to meet the needs of the boarding school. The post-test results show that the existence of the well gives confidence that water needs will be met with additional groundwater drilled wells from this activity.
