Processing Of Uranium Waste Using Alumina Silica Phosphate

Uranium waste generated from the utilization of nuclear technology on radioisotope production, nuclear fuel production, calibration of fuel post-irradiation, and the purification of uranium from yellow cake. Uranium is a long-lived radionuclides and hazardous if it was entered in human body, thus requiring appropriate treatment with high safety. The processing conducted by separated the uranium which was contained on waste with ions exchange process. Uranium has been separated, later then immobilized with the polymer. The study of simulation uranium waste processing using an Alumina Silica Phosphate (ASP) has been conducted. Simulation uranium waste with the concentration of 0,05 g/l was contacted to ASP with contact timer and pH as a parameters. The Alumina Silica Phosphate which saturated with uranium, later then immobilized with epoxy resin polymer by total of waste contents as a parameter. The immobilization was conducted by mixing ASP which saturated with uranium and epoxy resin. The study showed that the best composition of ASP was obtained at the ratio of 1:1, contact time of 15 minute, and pH of 7 with absorption of uranium about 93,5%. The characteristic of polymer and the immobilization waste showed that optimum of waste content is 20% of weight with the density of 1,0538 g/cm3; compressive strength of 19,96 kN/cm2 and there was not detected the leaching of uranium which out from the polymer-waste. Therefore, ASP can be used on processing of uranium waste and could be suggested to be applied on Radioactive Waste Management Installation

Tradisi Rambu Soloh dan Rambu Tukak di Kendenan Kecamatan Baraka Kabupaten Enrekang (Suatu Tinjauan Kebudayaan Islam)

Hal yang menjadi pokok permasalah pada penulisan skripsi ini ialah kepercayaan masyarakan Kendenan terhadap aluk tojolo, dan aluk ini terbagi dua yaitu rambu soloh dan rambu tukak. Dalam hal ini masyarakat beranggapan jika tradisi ini tidak dilaksanakan, maka akan terjadi musibah yang dikenal masyarakat Kendenan kamboroan (kena teguran). Untuk memudahkan pemecahan masalah, maka penulis mengemukakan masalah pokok yakni unsur-unsur budaya Isla, yang terkandung di dalam tradisi ini dan juga fungsinya bagi masyarakat Kendenan. Dalam upaya pengumpulan data, maka dipergunakan beberapa metode yaitu penelitian lapangan yang meliputi interview dan obeservasi. Hasil penelitian menunjukkan bahwa tradisi ini masih eksis hingga kini

(4) Kecukupan Anggaran dan Komitmen Organisasi bersama-sama memoderasi pengaruh Budgetary Goal Characteristics terhadap Kinerja Manajerial. Metode analisis data menggunakan uji prasyarat analisis, regresi linear sederhana dan moderating regression analysis (MRA). Hasil penelitian ini menunjukkan: (1) Budgetary Goal Characteristics berpengaruh positif terhadap Kinerja Manajerial, ditunjukkan oleh nilai koefisien sebesar 0,481, signifikansi 0,000, dan nilai thitung 5,018. (2) Kecukupan Anggaran memperkuat pengaruh positif Budgetary Goal Characteristics terhadap Kinerja Manajerial. Interaksi dengan variabel pemoderasi menghasilkan nilai koefisien 0,361, signifikansi 0,000, dan nilai thitung 5,177. (3) Komitmen Organisasi tidak memperkuat pengaruh positif Budgetary Goal Characteristics terhadap Kinerja Manajerial. Interaksi variabel pemoderasi mempunyai nilai koefisien 0,063, signifikansi 0,587, dan nilai thitung 0,546. (4) Kecukupan Anggaran dan Komitmen Organisasi bersama-sama memperkuat pengaruh positif Budgetary Goal Characteristics terhadap Kinerja Manajerial. Interaksi dengan variabel pemoderasi menghasilkan nilai koefisien 0,273, signifikansi 0,035, dan nilai thitung 2,151 serta F hitung 12,278

DEVELOPING SUPPLEMENTARY ENGLISH SPEAKING MATERIALS FOR NURSING VOCATIONAL SCHOOL

The objectives of this study are: (1) to develop appropriate supplementary English speaking materials for students in learning speaking skill in Tenth Grade in SMK Negeri 1 Bulango Selatan. (2) To see the students’ perception toward this supplementary English speaking materials in nursing vocational. The type of this study is Research and Development (R&D) by Borg and Gall (1983). The subjects of the research were X grade student. This study involved 30 grade ten students of nursing vocational. The instruments of the study were observation, interview, questionnaires and document analysis. The results of the needs analysis questionnaire were analyzed by using percentage. To validate the appropriateness of the book, the developed materials book was reviewed and evaluated by the expert. The result of needs analysis showed that in the part of students’ responded background it was found that the students have a lack experience about learning speaking English especially in nursing vocational. In the target needs and learning needs showed that the students needed materials for speaking which were attractive and interesting and based on nursing vocational. The product of this study was supplementary English speaking materials for nursing vocational. This product consisted of three units. Each unit had 10 activities and five stages related to curriculum 2013. Those five stages were observing, questioning, gathering information, associating, and communicating. The result of the book evaluation from the expert showed that the developed supplementary English speaking materials for nursing vocational school were categorized as strongly agreed. Moreover, the result of students’ perception about this product showed that the students mostly agree that the book suitable to be applied in the teaching and learning process especially in speaking. Thus, it can be concluded that supplementary English speaking materials for nursing vocational had been appropriated for X grade students in nursing vocational school.  Article visualizations

Implementasi Kontrol PID Pada Mesin Pengembang Roti

Besides the ingredient composition, another important thing in the process of making dough is proofing, ie. dough rising process prior to roasting process. Proofing process requires a stable temperature to ensure that the dough is well rising. The purpose of this research is to make a proofing machine that uses DHT11 as a temperature sensor. Proportional-Integral-Derivative (PID) controller is implemented to guarantee that the machine remains at the temperature of 350Celcius, in which the fermentation process would success. PID control has been implemented in fluorescent lamp which been set its dim light to generate heat until it reach a predetermined set point value. The temperature was monitored using LCD and set to remain stable with the help of fan. The proofing process will last for 15 minutes which ended by the sound of the buzzer. The testing result shows that the value of , , will reach set point value within 120 seconds
