Abstract

Suatu kajian bahan tabung katoda detektor Geiger-Muller tipe jendela samping (side window) telah dilakukan dengan tujuan menentukan faktor koreksi pencacahan terhadap serapan radiasi gamma, sehingga dapat ditetapkan jenis dan tebal bahan katoda detektor tersebut. Metoda yang digunakan adalah menetapkan koefisien serapan linier bahan tabung katoda terhadap radiasi gamma (y) yang berasal dari Co-60, CS-137, dan Na-22, dan kemudian menghitung faktor koreksi pencacahannya. Bahan yang dipilih antara lain tembaga, kaca, aluminium, dan stainless-steel (SS), dengan ketebalan masing-masing antara 1 - 4 mm, kecuati aluminium dengan ketebalan antara 0,03 - O,3 mm. Hasil yang diperoleh menunjukkan bahwa untuk berkas radiasi y dari Co-60, bahan tembaga, kaca, dan SS, tebal 1 mm, masing- masing mempunyai faktor koreksi pencacahan sekitar 7,92, 4,93, 1,44, dan untuk berkas radiasi y dari Cs-137 masing-masing bahan mempunyai faktor koreksi sekitar 7,33, 8,30, dan 14,82. Sedangkan untuk berkas radiasi dari Na-22, masing-masing bahan mempunyai faktor koreksi sekitar 1,53, 1,11, dqn 1,32. Bahan aluminium dengan tebal O,75 mm mempunyai faktor koreksi untuk radiasi y yang berasal dari Co-60, Cs-137, dan Na-22, masing-masing sebesar 1,07, 1,29, dan 1,20. Dari hasil perhitungan tebal optimal bahan katoda dari tembaga, aluminium, dan SS sebesar O,5 mm dan untuk bahan gelas sebesar 0, 025 mm. A material study for cathode tube of side window Geiger-Muller detector was carried out. Aim of the study is determine the counting correction factor to the absorption gamma radiation, so the type and thickness of materials tube can be settled. The method of this study is calculate the linear absorption coefficient of cathode tube materials to gamma radiation, in that transmitted by Co-60, Cs-137, and Na-22 isotopes, and then determine of the calculation correction factor. The materials choice are copper, glass, SS, aluminum, by O,03-0,3mm thickness. Results of this experiment show that copper, glass, SS, materials by 1 mm thick, have correction factor 7,92, 4,93, 1,44, respectively, in that Co-60 isotope is used in this experiment. The same material correction factors are 7,33, 8,30, 14,82, where Cs-137 isotope is as gamma source. If the Na-22 isotope is used as gamma source, so their correction factors are 1,53, 1,11, 1,32. For the aluminum O,75mm thick, has correction factor 1,07, 1,29, 1,20, in that Co-60, Cs- 137, Na-22 is used in this experiment. Conclusion of this experiment are: the optimum thickness of cathode material of copper, aluminum, SS, is O,5mm, whereas the glass cathode has O,025mm thick.

Abstract

Seiring perkembangan zaman yang semakin maju, berbagai kemajuan telah berhasil dicapai oleh manusia.  Hal tersebut meliputi segala aspek kehidupan, termasuk di dalam dunia konstruksi.  Berbagai kemajuan dalam dunia konstruksi telah melahirkan banyak hal-hal baru yang melingkupi aspek metoda konstruksi, manajemen, dan berbagai aspek lainnya.  Salah satu yang penting adalah kemajuan dalam penggunaan bahan bangunan.  Bahan bangunan baru yang banyak digunakan oleh masyarakat pada saat sekarang ini adalah baja ringan yang mulai menggantikan kayu dalam hal penggunaannya sebagai materi konstruksi rangka atap. Pekerjaan rangka atap baja ringan sampai sekarang masih menjadi monopoli agen-agen penyalur tanpa masyarakat mengetahui bagaimana desain rangka atap baja ringan yang benar. Dengan mengetahui konsep desain yang benar baik itu baja ringan maupun kayu, diharapkan dapat memberikan pertimbangan ekonomis bagi konsumen dalam menentukan pemilihan materi rangka atap

Abstract

The broken skin on fruit was the main problem on quality of duku. The availability of calcium on soil presumable having an effect on broken skin on fruit of duku. A field experiment to evaluated the effect of calcium in controlling the broken skin on fruit of duku was carried out in Kumpeh Ulu, Muaro Jambi, Jambi from Januari 2009 through to Februari 2010. The experiment was conducted on suboptimal land with soil acidity is 4.97 (pH H2O). Randomized Completely Block Design was used with 3 replications. The treatments consisted of 4 calcium carbonat doses i.e. 0 ton/ha, 1.0 ton/ha, 1.5 ton/ha and 2.0 ton/ha. The result showed that calsium carbonat doses decresing percentage of broken skin on fruit of duku and increasing concentration of hemicelluloce on fruit skin and fresh weight of fruit, calcium carbonat dose 2 ton/ha gave the lowest percentage of broken skin and the highest hemicelluloce concentration on fruit of duku. The highest of fresh weight of fruit at calcium carbonat dose 1 ton/ha.

Abstract

The aim of this experiment was to gain the accurate concentration of cycocel growth for controlling of yellow latex mangoesteen in different age level on field water stress.  This experiment was conducted in Koto Patah village, Keliling Danau, Kerinci, Jambi and was done from June until November 2011 at the altitude of 800 - 900 meter above sea level. Factorial experiment was arranged in a randomized block design. The first factor was cycocel concentrations: 0; 1.500; 3.000; 4.500; dan 6.000 mg L-1.  The second factor was levels of age plants: <30; 30-50; and >50 years.  The data were analyzed by using analysis of variance and continued with BNT test at ?=5%.  The results of experiment showed that: (1) the impact of cycocel on number and weight of perfect fruits depended on the age of manggoesteen; (2) manggoesteens which were less than 30 years old and treated with 4.500 mgL-1 cycocel could increase number and weight of perfect fruits; (3) manggoesteens which were older, 30-50 years old and above 50 years old needed less cycocel namely 1.500 mgL-1 for increasing number and weight of perfect fruis.

Abstract

Background: Based on the prevalence of anemia in Indonesia is still quite high, at 26.50% are young women, women of childbearing age (WUS) 26.90%, 40.10% of pregnant women and children under five at 47.00%. The results of the annual report Sigerongan Health Center of West Lombok in 2010 in the village of Dasan Geria anemia reached 17.17% and the increase in 2012 is 26.19%. Anemia in pregnant women will lead to high maternal mortality rate (MMR). Anemia in pregnant women can occur because one of the factors that Fe consumption patterns during pregnancy.Objective: To identify the relationship fe consumption patterns with the incidence of anemia in pregnant women in the village of Dasan Geria Lingsar District of West Lombok.  Methods: This study was an observational analytic cross sectional study in terms of time, the samples were used as many as 56 pregnant women. To determine the consumption pattern of Fe with the incidence of anemia in pregnant women conducted bivariate analysis using Chi Square test with a confidence level of 5% (α 0.05).  Results: Of the 56 samples based on the occurrence of gestational age the majority (82.14%) aged 2035 years, most of the work rate (64.29%) do not work, the level of education the majority (41.07%) Junior High School (SMP). Based on the results of statistical tests is known that there is no association between the consumption patterns of fe with anemia in pregnant women (p = 0.244: p> 0.05).  Conclusion: There is no relationship between consumption patterns fe with anemia in pregnant women.

Abstract

Bananas provide many health benefits because they have enough vitamin A for daily body vitamins. Benefits of bananas are not only found in the fruit alone. Banana stem is rarely used because it is considered not to have more benefits and is only considered as waste. However, banana stem can be transformed into various forms of beautiful crafts and high economic value. Banana banana is dried first before being processed into various handicrafts. The process of drying banana is very dependent on the weather conditions and the heat of the sun. Conventional banana drying process takes approximately 70 hours with a solar temperature of about 40oC. The solution to this problem is, design and manufacture a microcontroller based banana bum dryer using PI control to regulate the temperature and utilize the heater as an alternative heat source. This PI control uses Chien Regulator I and Chien Servo I tuning methods. In this Final Project, temperature and banana moisture content is measured. The control will adjust the exhaust fan when the temperature read by LM35 is displayed on LCD 4x20 for temperature monitoring. To adjust the AC-AC voltage controller voltage on the heater, depending on the angle of ignition of the TCA785 IC. DAC of Microcontroller ATMega16 will convert the digital data released microcontroller into analog voltage. The Kp and Ki values used are Kp = 5 and Ki 0.625 using Chien Regulator I method and Kp = 4,126 and Ki 0.414 using Chien Servo I method The drying process takes 16 hours with water content of 4.76% at ± 65oC using Chien Servo I method because the temperature response is more stable.
