Abstract

Measles is a serious problem in many developing countries included Indonesia. This research aims to find out how the general description of Measles, the death rate and the complications to sufferers. This research used Retrospective and takes the data from medical record of Pediatrics in General Hospital of Dr. R.D. Kandou Manado on January, 2000 until December, 2003. The research result is Measles happened in each 2 until 4 year and attacked most to 5-9 years old children. In addition, there are no gender differences. Failure to immunization was caused by primer and secondary. The death is found in measles sufferer who are not immunized and malnutrition. Bronchopneumonia is the most complication to the sufferers and the most treatment is symptomatic.

Abstract

Terminal bukan hanya sekedar dibangun sebagai peralihan dari suatu sistim transportasi ke sistim transportasi yang lain, tetapi harus memikirkan kenyamanan yang antara lain fasilitas utama dan fasilitas penunjang yang memadai. Tujuan dari penelitian ini adalah menganalisa ketersediaan sarana dan prasarana yang terminal Bus Pare-Pare sesuai dengan areal yang tersedia. Hasil Penelitian : 1). Untuk luas areal perparkiran dalam terminal sesuai dengan perhitungan pada jam puncak adalah 185, 64 m, dengan pembagian untuk areal kedatangan luas 92,82 m2 dan untuk areal keberangkatan luas 92,82 m2. 2). Untuk luas areal ruang tunggu penumpang adalah 703,71 m2 berkapasitas 1117 orang .3) Dari fasilitas penunjang dalam terminal masih sudah memadai, namun ada yang kurang terpakai. Kesimpulan Fasilitas utama dan penunjang dalam terminal masih sudah memadai, namun ada yang kurang terpakai akibat sedikitnya penumpang yang naik dan turun didalam terminal.

Abstract

Clean Water service in Tapa District still be very low, because of clean water processing system still use the system of Tardy Sand Filter processing (SPL) where its processing building still very simple and have old, network of distribution pipe a lot leak so that requirement of water resident will be clean cannot be fullfiled better. For that needed by a complete processing development planning so that clean amount of water required in Tapa District can be fullfiled. Planning clean water processing development use the projection analysis sum up the resident with the method aritmatika. This method assumed by a accretion sum up the constant resident so that can plan the domestic clean amount of water required, non domestic, clock culminate, head loss and capacities produce the water up to year 2015. Research result indicate that the clean amount of water required reach 70 litre/second, so that existing processing system this time that is SPL represent the processing which still modestly in its processing building meaning not yet complete, so that have improper again utilized because unable to again provide the water besih of]according to resident requirement. For that need the clean water processing planning by using Processing Installation Complete with system branch network of distribution pipe to fulfill resident requirement up to year 2015 by kontinu, with quality and amount.

Abstract

This research involved X1 Grade students of SMA Muhammadiyah Batudaa with total number of students were 21 students. It consist of 9 male students and 12 female students of 2008/2009 academic years. Technique in collecting the data was observation. This research was a classroom action research and it was done during one semester as two cycles. The observation result of teacher activity in first cycle got excellent criteria as 72, 72 and good criteria as 27,27. While in second cycle, it was improved as 36 % reached excellent criteria and 64 % reached good criteria. Besides that, observation result of students in first cycle is students who got an excellent criteria was 57,13 % and good criteria was 42,85% while in second cycle it was improved, that is students who got an excellent criteria was 29% and good criteria was 71%. Students achievement in first cycle were 13 students or 61,905 got score more, than 6,9 and 8 students or 38,09% got score less than 6,9. while the students achievement in second cycle was improved. It was 18 students or 85,71% got score more than 6,9 and 3 student got score less than 6,9 with classical absorption was 71,42%.Based on that result above, the applications of question student have strategy in atom structure lesson can improve student achievement. There fore, the hypothesis in this research can be accepted.

Abstract

The low consentration analysis of Lead, Cadmium, and Copper have been conducted by Differential Pulse Anodic Stripping Voltametry (DPASV) method using Hanging Mercury Dropiping Electrode (HMDE). DPASV method comprises two important steps. The firs step is deposition of a metal at the electrode sufase by electrolysis carry out by controlled potential. The second step is the metal stripping which have been precipitated at the electrode into the solution. The current, that is generated by stripping, is recorded by differential pulse mode. The optimum condition of instrumental parameters are deposition potential -700 mV, deposition lime 90 seconds, stripping rate 2000 rpm, 5 size of mercury drop and supporting electrolyte nitric acid at pH 1,5 which in produced by dilution of 50 L of 65% nitric acid suprapure until 10 mL solution. The precision (coefficient of variation) of analytical method was 9,24% Cd, 9,80% Pb, and 9,68% Cu. The accuracy of analytical method was 2,5% Cd, +1,76% Pb, and +7,30% Cu. The detection limit of analytical method was 29,9760 ng/L Cd, 42,4283 ng/L Pb, and 275,3222 ng/L Cu. The computation of concentration was based on twice addition standar technique.

Abstract

The research is experiment research that aimed to prove the different of students achievement that was taught by using SETS approach and by conventional significantly at MAN Limbotos students. The population were students of XA class, XB class and XC class of MAN Limboto in 2008/2009 academics years that consisted of 86 students. The sample was students of XA class and XC class that consisted of 50 students. The sample was taken by using Cluster Random Sampling technique. The instruments in collecting the data was essay test that validity and reliability had tested before. Method of data analyses were normality test, homogenity test and hypothesis test. At hypothesis test, it got tcount = 2.322, while ttable = 1,711. The result showed that students achievement that was taught by using SETS approach is better than students achievement that was taught by using conventional in Oxidation and Reduction Reaction lesson.

Abstract

Fosfat terdapat dalam air alam atau air limbah sebagai senyawa ortofosfat, polifosfat dan fosfat organik. Setiap senyawa tersebut terdapat dalam bentuk terlarut, tersuspensi atau terikat di dalam sel organisme dalam air. Dalam air limbah senyawa fosfat dapat berasal dari limbah penduduk, industri dan pertanian. Fosfat merupakan salah satu senyawa yang dibutuhkan oleh bakteri maupun tanaman, bila kadar fosfat sangat rendah (dibawah 0,01 ppm), maka pertumbuhan tanaman akan terganggu, bila kadar fosfat serta nutrient lainnya tinggi, maka pertumbuhan tanaman dan ganggang sulit dikendalikan, adapun nilai ambang batas (NAB) yang diizinkan adalah 0,2 ppm (PP. No 82 tahun 2001). Pengendalian dan pengawasan fosfat menjadi sangat penting, mengingat pentingnya fosfat bagi tanaman. Penentuan fosfat biasanya dilakukan dengan metode spektrofotometri dengan menggunakan asam aksorbat, SnCl2, atau dengan vanadomolibdat. (Greenberg, 1992). Namun metode tersebut memerlukan tahapan analisis yang kompleks, bahan pereaksi yang banyak dan mahal serta tidak dapat digunakan untuk analisa lapangan (in situ). Kendala ini dapat diatasi dengan metode potensiometri menggunakan elektroda selektif ion (ESI) karena tahapan analisisnya sederhana, cepat dan relatif murah serta dapat digunakan untuk analisa lapangan (Covington, 2006). Dalam penelitian ini dilakukan optimasi penambahan larutan dopan KH2PO4: 5, 10 dan 15 mL dengan tujuan untuk mendapatkan faktor Nernst 50-60 mV/dek. Karakteristik sifat dasar ESI yang dipelajari meliputi: faktor Nernst, rentang konsentrasi pengukuran, batas deteksi, waktu respon, usia pemakaian. Elektroda tipe kawat terlapis yang dihasilkan memiliki karakteristik faktor Nernst sebesar 59,05 mV/dekade, kisaran konsentrasi pengukurannya 10-3-10-1 dan batas deteksi 73.92 ppm
