Abstract

Flooding in Mutiara Witayu Recidence caused a big problem for the local communities. This situation led the government taking an action to relocate and plan a construction of retention pond as a settlement of the flood in the region. The purpose of this study was to get a sufficient retention pond capacity to accommodate the flood discharge at the sites. During it’s planning, hydrological analysis was conducted with rainfall data from the Office of Hydrology station for 20 years. Log Person III probability distribution and 5 year retense were used for the analysis. EPA SWMM program was used to analyze the flow of runoff existing in this study. The flooding problem was due to the runoff water which could not flow out into the outfall caused by the operation of the sluice. So it was necessary to accommodate the construction of retention pond during the discharge of the runoff of rainwater. The retention pond with a capacity of 23,000 m3 with a maximum depth of 1 m and ponded area of 23,000 m2, was planned in the study site. Based on the running program, it was found that the addition of a retention pond with that capacity could effectively accommodate the flood discharge at the sites. The cost required to build retention pond was Rp. 7,810,000,700.00 (Seven Billion Eight Hundred and Ten Million Seven Hundred Rupiahs).Keywords : Mutiara Witayu Recident, Flood, EPA SWMM, Retention Pond, Engineering Estimate

Abstract

Hydroxyapatite is a bioceramics that is widely used as bone and dental grafting material, catalysts and adsorbents. Hydroxyapatite is a calcium phosphate compound that can be synthesized from natural ingredients with calcium content such as coral reefs. Coral reefs have a CaCO3 content of 94.6%. This study aims to synthesize hydroxyapatite through the formation of Precipitated Calcium Carbonate (PCC) from coral reefs. The research procedure begins with the coral calcination process to form CaO which is then used as PCC by carbonation method. PCC as a source of calcium was synthesized into hydroxyapatite using sol gel process with variations in Ca / P ratio (1.67; 1.77) and aging time (20; 24; 28; 32; 36 hours). Synthesized hydroxyapatite was analyzed by Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray (EDX) and Brunaur, Emmett and Teller (BET). FTIR analysis results showed that in each sample there were PO43- and OH groups which indicated calcium phosphate compounds had formed. XRD analysis results showed the formation of hydroxyapatite compounds from an angle of 2θ which corresponds to the data (ICDD 01-073-6113). Hydroxyapatite synthesized in the ratio of Ca / P 1.77 and aging time of 20 hours gave the best results with hexagonal crystal structure, crystal size of 10.08 nm, surface area of 90.413 m2 / g and mole ratio of Ca / P 1.71.Keywords : aging, carbonation, PCC, sol-gel method.

Abstract

Development Region V consists of Marpoyan Damai District, TampanDistrict, and Payung Sekaki District, with an area of 140,96 km2 and a population of 510,107 people. In 2016, the waste generated from this development area settlement was 1,049,179 l/day. The development region V with high data on population and waste generation per day is the biggest contributor to waste and if the management of the waste is not optimal that will cause the existence of illegal dumping increased.The purpose of this study is to map and analyze geophysical, anthropogenic and community characteristics. This research was conducted with a direct survey methodto the study area with GPS Garmin 60CSx type, then mapped using GIS software, ArcMap 10.1. In the V development region, 33 locations of illegal dumping werefound. There were no illegal dumping found at a distance of ≤ 15 m from the river. In the distance parameters of arterial and local roads, the existence of illegal dumpingis generally located at a distance of <5 m or at the shoulder of road, that can caused by the accessibility or of the community to dispose of garbage to that location easily.For the land type, mostly the community will be waste disposal on the main road. On the road type parameters Illegal dumping, commonly were found on arterial roadsbecause the service center for transporting garbage is generally on arterial roads. The insufficient number of legal dumping causes the number of illegal dumping increased. The number of illegal dumping increases with the high population density.The level of education and knowledge will influence attitudes and behavior of waste management, because low levels of education and lack of knowledge will improve unhealthy attitudes and behavior. The number of illegal dumping increased with theincrease in the number of respondents with the type of work of traders.Keyword: Geographic Information System(GIS), Illegal Dumping, ArcMap, Mapping of Illegal Dumping
