The quality of universities, especially study programs in Indonesia is measured based on accreditation conducted by BAN PT. According to BAN PT the quality is measured based on 7 main standards, one of them is Student and Graduate. One of the problems that still be the subject of discussion related to student failure is about the students who graduated not on time. Students graduating not on time are students who can not complete their studies in accordance with the provisions of time given. The existence of a graduate student is not timely of course cause problems and potentially drop out that affect the quality of education and accreditation. A system that predicts students' graduation is required by evaluating their learning outcomes. The timeliness of graduating students can be done with data mining techniques to find graduation patterns of students who have graduated which then used as a basis to predict students' graduation in the next year. This study showed that Naïve Bayes was able to classify the correct data testing on average by 86.16% and 13.84% error. In addition, other information obtained from the data testing used that the students who entered from the PMDK Pass graduated on time as much as 40%, other paths graduated on time by 26.7%, and pass filter exam on time 13.3%.
Lumpue Beach Subsurface Profile Analysis of Parepare City. This study aims to analyze the subsurface profile of Lumpue beach which is directly contaminated with activities around the coast. In this study, the Wenner Schlumberger method was used in the Lumpue beach area, Perepare City, South Sulawesi Province. The tool used is a multichannel geoelectric with a maximum length of 480 m in each trajectory, in this study there are 3 trajectories in which the first trajectory is 480 m with depth as deep as 91.2 m and the resistivity results obtained range from 0.207 -> 97.8 Ωm which identified as alluvium containing clay soil, silt soil, sandstone and pyroclastic rock bolder that has been contaminated by sea water. At lane 2 intersects the middle lane 1 with a length of 240 m and identified depths of 91.2 m, the recorded resistivity results range between 5.52 -> 623 Ωm where the resistivity value identifies the alluvium material, which contains clay, silt soil , sandstone that has been contaminated with water and the presence of some pyroclastic rock inserts that are contaminated by water. Whereas lane 3 intersects lane 1 at the end with a lenght of 240m and a depth of 91.2 m, while the recorded resistivity results range from 0.354 - 11776 Ωm where from the recorded resistivity results the material contained in lane 3 is the inserted alluvium material. by pyroclastic rocks. The area covered by the track is an area with alluvium material which is an alluvial unit and most of it is contaminated by water, either by sea water or fresh groundwater and is inserted by pyroclastic rocks.
The purpose of the study is to assessments the coastal vulnerability index in the Parepare bay, the beach is Lojie area, District of Mallusetasi, Barru Regency, Lumpue and Lapakaka areas, District of Bacukiki, City of Parepare South Sulawesi Province with including some aspect that is morphodynamic, coastal characteristic, hydro-oceanography, and coastal vulnerability index. Geomorphology in the study area was grouped in the formation of the morphology of terrain, wavy, and hills. Stratigraphically is composed of Parepare Volcanic rocks (Tppv), and Alluvial Deposits (Qa), divided into 4 rock units namely alluvial units, trachyte unit, tufa unit, and volcanic breccias. unit. Based on that, coastal characteristic in research area divisible in 3, that is rock coastal, sandy coastal and mud/mangrove coastal. Hydro-oceanography condition in research area that is about current with velocity of current average is 0,191 m/s with direct current is N 97° E (southeast), wave with average of high wave velocity of current average is 0,191 m/s with direct current is N 97° E (southeast), wave with average of high wave is 56,40 cm, velocity of wave is 2,4 m/s and wave maximum energy as big as 10368 joule, tide subsides in research area with high tide 1.3 meters and low subside is 0,6 meters with sea-level high 1 meters. Coastal morphodynamics and vulnerabilities of the Parepare Bay on the northern part of Lumpue Coastal, which was dominated by sand-sized sedimentary material, found multiple bars due to low/weak energy wave activity, sloping beach morphology, and predominantly residential areas. It is thus categorized as a dissipative type beach with a low level of vulnerability (CVI = 6). As for the south of the study area, the Lapakaka Coastal and Lojie Coastal are dominated by gravel and coarse-sized sedimentary material, found coral reef fragments due to high energy wave activity and mangrove found in coastal areas. Then this beach can be classified in the type of reflective with a high level of vulnerability (CVI = 53.66 n 37.94).
Research on Losari beach sediment profiles and distribution aims to analyze subsurface conditions and composition of coastal sediment materials based on hydrodynamic processes consisting of currents, waves and tides, analysis of sediment textures and subsurface profiles. The research method used in the form of primary data collection consisting of hydrodynamic and coastal characteristics data, and sediment data collection using SES 2000 and grab sampler. Bathymetry measurements show depths ranging from 0.5 to 13 m. Current direction from west to east and southwest to north at speeds of 0.05 - 0.25 m / sec, wave direction from west to east with speeds between 1.50 - 6.50 m / sec and height of 0.30 - 1.00 m. The distribution of the type of sedimentary material consists of sand, silty sand, silty clay and clay. This research is expected to be useful in adding evidence and information regarding the profile and distribution of coastal sediments, both to the local government and the surrounding community, so that it can become a reference for local government and as a material for consideration in efforts to deal with coastal damage and serve as a basis for decision making and policies to preserve nature and develop tourism.
This study aims to analyze heavy metal elements in Lumpue Beach. Characterization of Lumpue Beach sediments in addition to the megaskopis and petrographic observation approach, determination of mineral chemical aspects using ICP-OES analysis was also done. This analysis done on 7 samples of very fine sand obtained from sieving and aimed to determine the level of heavy metal elements on the ppm scale. Based on ternary plotting diagrams, that the dominant Lumpue Beach is composed of sedimentary texture very fine sand - coarse sand. The ratio of Pb elements in the study area has an average level of 41.38 ppm and a trend line R2 = 0.25, Cd has an average level of 1.65 ppm and a trend line R2 = 0.12, Cu elements has an average level of 14.5 ppm and a trend line R2 = 0.02imes and Zn element has an average level of 62.125 ppm and a trend line R2 = 0.0022. They are indicated to exceed normal limits. Based on the use of Pearson method with two paired variables on metals Cu, Fe, Ni, Zn, Pb, Ti and Mn, it is known that Cu metal has a very weak correlation with Fe, Zn, Ni, Pb and Ti, while Fe metal has a strong correlation to Zn., Ti and Mn but have a weak correlation with Ni and Pb. Fe and Al metals are deposited with low values, this occurs in the concentrations of the two metals and follows the sediment fraction controlled by currents and tides.
Barites can form in the marine environment as autogenic minerals, which are dominated by barium, carbonate and sulfate elements. Barite mineral distribution on Marl are occurred on two location which are Ralla and Barru Area (1) Ralla, irregular shape (2) Barru, barite concression, slightly rounded. The study aims to determine sulfat geochemistry as chemical bond and the influence of barium depositional environment. Applied Petrography, SEM and XRD Analysis on Marl, Andesite, and Barite mineral. Tabular rosset texture with minor Calcite are indicated that source of Sulfat material comes from Neritic environment (Barru) and penetration of hydrothermal solution.
