ESTIMASI NILAI PENURUNAN KESEHATAN AKIBAT POLUSI GAS NOX DI UDARA DKI JAKARTA
Get PDFThe aim of this research is to estimate the value of health degradation caused by nitrogen oxide (NOx) gas as one of the air pollutions in Jakarta Province. The economic growth in urban area may affect lifestyle which will increase the energy demand. Fossil fuel as the main energy emitting some gases to the ambient, one of them is NOx gas. In this research analysis of factors that influenced NOx ambient concentration is based on the socials, economics, and meteorological data from Indonesia Statistics Center (BPS) and Bureau of Meteorology and Geophysics (BMG). The prediction of the cost that has to be paid by the persons who are exposured by NOx gas and will get respiratory symptomps is done by developing the dynamic simulation model. The result of this research is by 2025 the Jakarta residences that will have respiratory symptomps caused by the NOx air pollution should pay about 1 trillion (1012) rupiahs. To reduce this pollutant it is recommended to develop public policies based on the economic and environmental concern
BENTUK NORMAL SMITH DAN MATRIKS BAIK KIRI/KANAN
Get PDFThe Smith normal form and left good matrix have been known in matrix theorem. Any matrix over the principal ideal ring has a Smith normal form. The Smith normal form of a matrix has many applications on various fields such as a solution of Diophantin linear equation and differential equation system. Furthermore, a matrix A with entries in a commutative ring R with unity is left good if for every vector x, the ideal áxAñ is the same as the ideal áAñ. This paper discusses the relation between the Smith normal form and left good matrix. The relation is as the following: matrix A with entries in principal ideal ring of size m by n, with
m < n, has Smith normal form [Im, O] if only if A is a left good matrix
PENGARUH FAKTOR INTERNAL MAHASISWA TERHADAP PARTISIPASI MAHASISWA DALAM TUTORIAL ONLINE
Get PDFThe optimal learning process conducted by students will reflect the result in their study evaluation. The final score of the subject is determined by two important components: Tutorial (60%) and final exam (40%). Student’s participation in online tutorial (tuton) contributes 10% and 50% for tutorial assignments. Because of the students’ participation in online tutorial (tuton) decreases, whereas it gives a significant contribution, there are a number of factors causing the limit number of students participation. This factor, temporary, is considered by the cause of the student’s internal problems. This research is aimed at analyzing the impact of student’s internal problems to his/her participation in tuton. This is a descriptive qualitative research using purposive informant. Data gained by having an in-depth interview, questionnaire, and observations. The data were analyzed by conducting data category process, data reduction, data display, data interpretation, and data analysis. The results show that student’s internal factor: the low ability in using learning technology and students activity, have a significant impact to his/her participation in tuto
PERBANDINGAN KEMAMPUAN MEMECAHKAN MASALAH STRUKTUR ALJABAR ANTARA MAHASISWA JARAK JAUH DAN MAHASISWA TATAP MUKA
Get PDFLearning to solve problems is the principal reason for studying mathematics. Teachers play important roles to enhance students’ ability to solve problems in mathematics. While teachers’ presence is common situation in face-to-face education system, it’s hardly the case in distance education system. The situation often post questions on the quality of distance education system, especially in the field of mathematics. The aim of this research was to compare students’ form distance education system and face-to-face system in term of the students’ achievement in problem solving. Data collected through questionnaires and written test are analyzed quantitatively to compare the algebra structure problem solving competences between the groups of students based on Polya's phase guide for solving problem. Analysis shows that the average scores of face-to-face students are slightly higher than distance education students. However, on one out of four competences -how to prove the subgroup- there is no differences in the two groups average score
ANALISIS KANDUNGAN ZAT GIZI SOUN GANYONG (Canna edulis) DAN DAYA TERIMA KONSUMEN
Get PDFFood resistance will be strengthened with diversity of food products. In order to augment raw materials for soun, a variety of white starch noodle, a research was conducted using starch of ganyong (Canna edulis). The purpose of the research was to survey the nutrient content and consumer acceptance of soun ganyong. Nutrient content was analyzed by proximate method and consumer acceptance was analyzed by organoleptic test. The result showed that carbohydrate content was 83.86% to 85.12% higher than the carbohydrate of white rice, main food supply of the population. Therefore, it can be suggested that soun ganyong be used as supplement for the carbohydrate food supply. The organoleptic test showed that consumers prefer (acceptability) the color, taste, and aroma of the white variety than the blue one, while the texture for both varieties was generally accepted
ORGANISASI PEMERINTAH DAERAH: MEWUJUDKAN TATA PAMONG YANG BAIK (GOOD GOVERNANCE)
Get PDFThe application of Government Regulation Number 22 /1999 on local government has an important effect on the development of local government. Local government has more autonomy and larger opportunities to develop their region. However, the application of local autonomy will be meaningless if local government does not improve their performance. As an organization, local government has a bureaucracy culture. Generally, bureaucracy culture has not support the aim of the local government. Bureaucracy still has a problem that should be solved right away, among others are: personal performance, payment system, and ethics. Public service is another aspect which should be improved. Local autonomy regulation will be effective if local government can improve the public administrator function
KANDUNGAN ANTIOKSIDAN BEBERAPA LALAPAN
Get PDFThe product of fat oxidation on food has a significant effect towards human’s health, especially those who often consume it. It has been known for long time that vegetables, fruits, and fish have an ability to stifle Free Radical through the activities of antioxidant belonged to them. Among some kinds of antioxidant, natural antioxidant is the one which does not have any side-effects. This research is aimed to know the ability of antioxidant consisted in kemangi leaves, kemangi, rende, poh-pohan, and lettuce to stifle Free Radical. Based on the result of spectrophotometer test towards those dishes of raw vegetables (lalapan), kemang leaves have the most antioxidant with 0,488 absorption, followed by rende leaves with 0,394 absorption, kemangi leaves with 0,326 absorption, poh-pohan leaves with 0,176 absorption, and lettuce with 0,1635 absorption. Based on the spectrum analysis, it can be seen that lettuce leaves have more effective antioxidant to stifle Free Radical
PELUANG PEKERJA WANITA DALAM MEMILIH LAPANGAN PEKERJAAN PERTANIAN DAN NON PERTANIAN DI KOTA BATAM
Get PDFBatam strategically located at the international shipping route; therefore it attracts investors and labor market. About 52% of citizens of Batam is female. The purpose of this research are to identify characteristics of female labor force; to recognize social and demographic factors that influence female labor in selecting job in the city of Batam; and to recognize the probability and tendency of female labor in selecting job by social and demographic aspects. The 2000 population census indicates that social and demographic characteristics influence the way female labor selecting jobs. There is a tendency that younger female labor is more interested working in non-agricultural sector. Female labors with high school education and higher education have larger probability to get jobs in non-agricultural sector as compare to female labor with lower education
EFEKTIFITAS KORAN MASUK NAGARI (KMN) PADANG PARIAMAN HARIAN UMUM HALUAN DI KECAMATAN PARIAMAN SELATAN
Get PDFThis article defined some informations about the total ammount of Koran Masuk Nagari (KMN) Padang Pariaman where this news is very famous for local people. It also has many functions such as to measure a main message on the news, to measure the level of content messages in distribution, and identify some problems, which will be happened on distribution.The research were implemented in Kecamatan South Pariaman and used 57 house hold samples. Hence, I used qualitaitive method which has category in descriptive analysis. The most favourite information is about religion (21,44%), and the capability of understanding content of messages has got the lowest point (2). Because of KMN had not some special cars and staffs to distribute the news, therefore the distribution from publisher to people always be late and this is a classic problem for KMN to expand. The conclusion from this research showed that KMN Padang Pariaman was effective to improve the local people interest to read it. And the fact KMN is always be waited by people in Padang Pariaman
METODE ELEMEN HINGGA UNTUK PENYELESAIAN PERSAMAAN SCHRÖDINGER ATOM HIDROGENIK
Get PDFThe research computed the energy levels and radial wave functions of the Hydrogen Atom. The method used for computation was FEM (finite element method). Using the variational method approach, FEM was applied to the action integral of Schrödinger equation. This lead to the eigenvalue equation in the form of global matrix equation. The results of computation were depended on boundary of the action integral of Schrödinger equation and number of elements. For boundary 0 - 100a0 and 100 elements, they were the realistic and best choice of computation to the closed analytic results. The computation of first five energy levels resulted E1 = -0.99917211 R∞, E2 = -0.24984445 R∞, E3 = -0.11105532 R∞, E4 = -0.06247405 R∞ and E5 = -0.03998598 R∞ where 1 R∞ = 13.6 eV. They had relative error under 0.1% to the analytic results.
