Abstract

ABSTRACT This study aims to determine the density level of seagrass (T. hemprichii), the type and density of gastropods associated with seagrass, and the density relationship of seagrass with gastropod density in the waters of Nirwana Beach, Padang City. Determination of sampling locations using survey methods by making observations directly to the object of research to see closely the activities at the research site. This research was conducted in March - April 2018. Gastropod samples obtained were then analyzed at the Marine Biology Laboratory. The results of measurements of water parameters in the water temperature range from 28-29o, salinity ranges from 30-31 ‰ and water pH ranges from 7-8. Sediment types namely sandy gravel with organic matter content ranging from 4.68-5.66. For seagrass densities each station 96.44-142.34 stands / m2 and for each zone ranged from 83.67 to 163.56 stands / m2. Gastropods found in 10 species. Gastropod density at each station ranges from 82-118.4 ind / m2. For each zone ranged from 68.7 to 82.08 ind / m2 with the highest density in the species Clypeomorus sp. Linear regression analysis states that the seagrass density relationship with gastropod density from the value r = 0.96 is classified as very strong. Keywords:Thalassia hemprichii, Gastropoda, Nirwana Beach Padang City

Abstract

The safety and sustainability of an energy source, along with biodegradability is a parameter whether an alternative energy considered successful or not. Currently, biodiesel is an environmentally friendly and has low manufacturing cost. Biodiesel cathegorized as fatty acid methyl esther (FAME) which is generated from fat or oil. In this research, palm fatty acid destillate (PFAD) is used as raw material to produce biodiesel. PFAD is converted into FAME through single stage estherification. This estherification reaction combine 25 gram of PFAD with 97 gram of methanol with mixing rate of 350 rpm at 60˚C for 1, 2, and 3 hours. 0,25 gram of metal-hydroxyapatite catalyst (Cu-HAp, Co-HAp, Ni-HAp, dan HAp) will assist in the process of converting PFAD into FAME. The focus of this study is the effect of time and type of metal-HAp on the conversion of PFAD into FAME. The highest yield of biodiesel is acquired at the usage of (3%) Cu-HAp catalyst for 3 hours. Physical test result has fulfilled SNI 04-7182-2006 which includes 0.84 g/ml density, 4.8 cSt viscosity, 120 ˚C flash point, 61.48% yield, acid number of 0.73 mg KOH/gr oil. Based on the GC-MS (Gas Chromatography-Mass Spectrometer) analysis, the main component of the PFAD-based biodiesel is 53.1% hexadecanoic methyl esther, 32.81% 9-octadecanoic methyl esther and 5,93% 9,12-octadecadinoic methyl esther.Keywords: Biodiesel, Estherification-transestherification, Methanol, Metal-HAp catalysts, PFAD

Abstract

ABSTRACTThe problems that occurred at SDN 18 Kampung Pansur were from 3 teachers who taught in grades 1,2 and 3, only about 35% were of good quality in applying thematic learning approaches, the rest were 65% who taught grades 1,2 and 3 including in qualifications the value is lacking in applying thematic learning approaches. For this reason, with school action research through academic supervision, there can be at least some solutions / efforts to improve the ability of teachers to implement thematic learning approaches at SDN 18 in Kampung Pansur. With research procedures (PTS), namely through planning, action, observation and reflection in cycle 1, there is a significant increase in the cycle 2 action. Based on the results of the implementation of the study shows that the implementation of the first cycle obtains a change in the increase in significant results in the second cycle. of the 3 teachers in grades 1,2, and 3 who previously qualified for less in applying the thematic learning approach, now 29% have qualified enough and 30% have good grades. This means that through this study there is an increase of around 30% overall .

Abstract

This study aims to determine the policy the law against the act of unregistered marriage by the penghulu based on positive law in Langsa City, Then the factors that influence unregistered marriage and the impact of unregistered marriage according to positive law. That policyThe law against the act of unregistered marriage by the penghulu based on the Criminal Code that occurred in Langsa City violated the lawArticles 151 and 143 Draft Law on Material Law for Religious Courts (RUU HMPA)In 2007, it was judged that the act of unregistered marriage by the head of the village violated the criminal law and state administrative law, but so far in Langsa City there has been no confirmation of the crime against the perpetrators of the act of unregistered marriage. The factors that influence unregistered marriages in Langsa City are: factors of lack of awareness of the law, Religion factor, factor economy and status of children born considered an illegitimate child, so that in the eyes of the law he does not have a civil relationship with his father but only has a civil relationship with his mother and his mother's family (Articles 42 and 43 of Law No. 1 of 1974 and Article 100 KHI). The impact of unregistered marriage according to positive law due to not complying with the law in Pidie Regency, namely: the position of the wife is not recorded in the state administration, the position of children born from unregistered marriages is considered a child out of wedlock (considered illegitimate) by the State and joint property (Gono-Gini) in marriage if there is a divorce, the wife is difficult to get rights to joint property them if the husband does not give. In addition, if there is an inheritance left by the husband, because the husband dies, the wife and children are also very difficult to get the rights to the inheritance.DI hope the community does not carry out serial marriages, especially for women so that they do not become disastrous in the future. It is hoped that the Government will confirm criminal acts for perpetrators who carry out unregistered marriages, so that people do not carry out behavior that is detrimental to other parties.

Abstract

This thesis aims to determine the effect on net profit margin of return on assets, total asset turnover of return on assets, as well as between the net profit margin and total asset turnover is common - equal to the return on assets. The hypothesis tested is: there is a positive influence and a significant net profit margin of return on assets. There is a positive influence and a significant total asset turnover of return on assets. There is a positive influence and significantly between the net profit margin and total assets turnover is common - equal to the return on assets. The method used in this research is descriptive method and verifikatif. Population in this research is PT. Astra International Tbk. And the sample of Financial Statements and Loss Balance Sheet - Profit .. Data were analyzed with descriptive statistics, for statistical hypothesis testing used a simple correlation, multiple and partial and multiple regression.The results showed that: First, there is a positive influence and a significant net profit margin of return on assets, with a correlation coefficient of ry1 = 0.694 α = 0.05 level. Second, there is a positive influence and a significant total asset turnover of return on assets, ry2 correlation coefficient = 0.754 at α = 0.05 level. Third, there is a positive influence and significantly between the net profit margin and total asset turnover is common - equal to the return on assets by the regression equation Y = - 0.046 + 0.504 X1 + 0.095 X2, Ry1.2 correlation coefficient = 0.951 at the level of α = 0, 05.The results of this study are expected to be useful for the improvement of the quality of financial reports of PT. Astra International Tbk to consider this conclusion. That the return on assets (Y) can be increased by increasing the net profit margin (X1) and Total Assets Turnover (X2).

Abstract

Misalkan G adalah graf terhubung dengan V (G) adalah himpunan titik G. Misalkan W ⊆ V (G), dimana W = {w1, w2, · · · , wk}. Untuk sebarang titik v ∈ V (G), representasi titik v tehadap W dapat ditulis sebagair(v|W) = (d(vi, w1), d(vi, w2), · · · , d(vi, wk)), i = 1, 2, · · · , n, 1 ≤ k ≤ n.Jika representasi setiap titik di V (G) terhadap W berbeda, maka himpunan W disebut sebagai resolving set. Resolving set dengan kardinalitas minimum disebut resolving set minimum atau basis, sementara kardinalitasnya dinamakan dimensi metrik, dinotasikan dim(G). Misalkan terdapat dua graf siklus Cn, n ≥ 3 dengan himpunan titik Cn pertama V (Cn1) = {x1, x2, · · · , xn} dan himpunan titik Cn kedua V (Cn2) = {y1, y2, · · · , yn}. Tulisan ini mengkaji kembali makalah [1], yang membahas tentang penentuan dimensi metrik dari graf barbel B2n, dengan B2n ' 2Cn + {xnyn}, dimana diperoleh bahwa dim(B2n) = 2.Kata Kunci: Dimensi Metrik, Resolving set, Graf Barbel
