Abstract

Research has been carried out which aims to determine the quality of drinking water in refill drinking water in Lala Village, Namlea District, Buru Regency. This type of research is quantitative descriptive with a laboratory experimental approach which aims to obtain an overview of the content of Escherichia coli and calcium carbonate (CaCO3) bacteria in refill drinking water. Based on the results of the study, it was found that for the biological quality of drinking water samples at the refill drinking water depot in Lala Village there were two polluted refill drinking water depots and were detected to have an average total Escherichia coli in sample I was 5/100 ml and sample II 5/100 ml. As for the chemical quality, it shows that all drinking water samples consist of 4 samples, the hardness as CaCO3 is still within the normal limit, namely 200.927 to 285.007 mg / l. So it can be concluded that all refill drinking water depots in Lala Village are safe for CaCO3 hardness, while for the biological quality of depot I and depot II are not suitable for consumption.

Abstract

Road intersections are places where traffic conflicts occur. The volume of traffic that the road network can accommodate is determined by the intersection capacity of the road network. This study aims to determine the magnitude of the intersection capacity, degree of saturation, delay and queuing opportunities at the RH-Mart Namlea City intersection, whether the solution or alternative solution to the traffic jam problem at the RH-Mart Namlea City intersection. This research was conducted at the unmarked intersection in the city of Namlea, especially the RH-Mart intersection. The intersection performance analysis includes capacity (C), degree of saturation (DS), delay (D); and the probability of queuing QP% 'was calculated using the MKJI 1997 method. The results showed that the intersection capacity (C) = 632.30 pcu / hour, the degree of saturation, for all directions at the intersection arm and for all survey days Ds <0.75, namely on working days obtained Ds = 0.071 and 0.083, for short days Ds = 0.087 and 0.068, and on holidays Ds = 0.068 and 0.070. it means that there is no need for improvement of the intersection geometry, control of total intersection currents, and control of the flow with signs to maintain the desired degree of saturation (DS ≤ 0.75). Because the Ds value obtained is very small there are no delays and queuing opportunities that occur. Keywords: Unmarked Intersections, Intersection Capacity, Degree of Saturation. Namlea

Abstract

Namlea Village is one of the villages in Maluku Province, Buru Regency, currently developing in terms of economy and population growth. Land-use changes have an impact on soil infiltration, with the amount of surface runoff which has the potential for flooding at several points to become a problem in Namlea Village, significant surface runoff on the clove flower road causes the drainage channel on the road to be unable accommodate the discharge of water that enters the drain. This research was conducted by referring to primary data and secondary data. Primary data, data obtained by conducting field surveys (research places/locations), while secondary data, data obtained directly from related agencies as supporting data in the final project writing. This. The planning analysis results with rainfall data taken from the BMKG (Meteorology, Climatology and Geophysics Agency). By paying attention to the hydrological design criteria table for the urban drainage planning system, appendix 8 and the data on water users in table 4.12 and population density projection data for 2015 taken from the statistical agency. Then the results of our planning analysis take a maximum plan age of 2 years with a maximum rainfall = 410,907 mm, with a planned discharge due to rainwater runoff Qp = 1,167 m3 / s and release due to household waste Qlimbah = 0.0025 m3 / s, then the total discharge Qtotal = 1.1695 m3 / s, with the results of the above analysis, the existing channel capacity is unable to accommodate water discharge due to rainfall or burst due to household waste because the current channel discharge is only able to accommodate a release of Q = 0.44 m3 / s with a volume capacity of V = 209,375 m3, while the volume capacity of the channel on Jalan Bunga Cengkeh is following the current population density and must be able to accommodate a discharge of Qtotal = 1.1695 m3 / s. With an average annual volume capacity of V = 25612.05 m3. The existing channel dimensions must be rehabilitated according to the planning analysis results that the author had planned with a trapezoidal channel cross-section. Keywords: Evaluation of drainage channels, channel capacity, due to rainwater discharge

Abstract

 This paper presents a fact about the Class Average of Two Generations ( 2011 and 2012 generations).  It consists of five classes, includes Extension, A, B, C, and D. But the writer would like to analyze one class only, namely D class. Because the average class data stated, there is a drastic increasing point. To achieve the credibility of this research, the researcher uses average class data from another generation. So, the writer does the comparison process between 2011 and 2012 generations. Finally, through this paper, we can prove that some factors influenced the class average of two generations from D classes on nursing students at the Moluccas Christian University of Indonesia. Shortly, we can conclude that the D class of the 2012 generation has a higher class average point than the 2011 generation.
