Abstract

Modified Poschl Teller potential is a potential model used to describe behavior of inter moleculer forces. The spectrum energy and wave function of the particle affection in modified Poschl Teller potential are obtained by solving the Schrodinger equation, using hypergeometric equation and supersymmetric method. The energy spectrum and wave function are obtained from hypergeometric equation, which is constructed from Schrodinger equation through variable substitution. The energy spectrum and wave function are obtained using raising and lowering supersymmetric operator and applying shape invariance property. The solution of those equation of the energy spectrum and wave function obtained using these two methods are exact solution. Further, the wave function and density probability are visualized using computer simulation.

Abstract

The progress of information technology is rapidly increasing, making it easy for everyone to access information quickly, including the Puasana villagers in getting information from the village government. Information technology also makes it easy for village officials to collect data on all village potentials in a village information system (SID). The existence of this system can also provide an overview of the potential of the village for the wider community, so that it can open economic opportunities to improve people's lives. Puasana Village, is one of the villages that have a variety of natural resource potentials that needs to be published continuously. A qualified village apparatus in the field of information technology is needed so that this effort can be realized. Therefore, assistance is needed to Puasana village officials to be able to operate SID so that they can update their village information at any time. In addition, this SID can also facilitate the village administration process because it is no longer done manually. Well-organized and good information will make it easier for people to get the information they want. Based on the results of the mentoring shows that with the availability of SID the community can easily access village information through online and offline. Village officials also gained additional knowledge related to making SID and could update the village profile at any time

Abstract

Research and manufacture of optimum nuclear potential parameter optimization program for fusion reactions between heavy cores has been successfully made using Wong formula approach which is supported by Borland Delphi 7.0 visual programming language. The study was conducted specifically on the 16O+70,72,74,76Ge system by varying the value of the diversity parameter (a) and setting the depth parameter value (V0) and the radius (r0) parameter of six data. The three parameters must be set so as to produce the same VB value with the reference VB value. The resulting cross-sectional value of each input data has a different level of accuracy for the energy above VB. The results of cross-sectional calculations are then compared with the experimental results data. The Chi Square values of each cross-sectional data are interpolated with the input value a to produce a parabolic graph. The minimum peak of the graph represents an optimum value with the lowest Chi Square that can be used to determine the cross-sectional value of the fusion reaction closest to the experimental data. Keywords: nuclear fusion reaction, Wong formula, cross-reaction, heavy core, Chi Square, interpolation.

Abstract

We study the heavy-ion reaction at sub-barrier energies for 16O+144,154Smsystems using full order coupled-channels formalism. We especially investigate the effect of fusion and quasi- elastic barrier distributions on the surface diffuseness and the coupling radius parameters of the nuclear potential for these systems. We found that the structure of fusion and quasi-elastic barrier distributions is more sensitive to the surface diffuseness and coupling radius parameters for the reaction with spherical target, 16O+144Sm systemcompared to the reaction that involves the deformed target, i.e., 16O+154Sm system. In more detail, the results of coupled-channels calculations for the fusion and the quasi-elastic barrier distributions for deformed target are not sensitive to the choice of the coupling radius and surface diffuseness parameters. In mark contrast, the structure of the fusion and the quasi-elastic barrier distributions for spherical target are very sensitive to the coupling radius and surface diffuseness parameters. We found that the small surface diffuseness parameter smeared out the fusion barrier distributions and the larger coupling radius smoothed the high energy peak of the quasi-elastic barrier distributions. We also found that the larger coupling radius, , is required by the experimental quasi-elastic barrier distribution for the 16O+144Sm system whereas the experimental fusion barrier distribution compulsory the small value, i.e., .

Abstract

The numerical simulation for calculating the cross section of fusion reaction is done by using Wong formula. We especially calculated the cross section for the fusion reaction of light systems, i.e. 12C+12C, 16O+12C and 16O+16O reactions. We compared the obtained cross section with experimental data. In order to check the accuracy of the calculations, the chi-square analisys is then permormed. We found that the simulation results of the fusion cross section obtained using Wong Formula well explain the experimetal data of the fusion cross section for the 12C+12C, 16O+12C and 16O+16O reactions. This finding indicates that the Wong formula can be used for studing the fusion reaction of light systems.

Abstract

It is well known that the energy content of fuel is characterized by its calorific value which is usually measured by using a bomb calorimeter. In many analysis, the calorific value is usually related with the proximate analysis results. In this study, the calorific value predicting program based on the proximate analysis data using the fuzzy inference system with Mamdani method has been developed. In our analysis, the proximate analysis data of moisture and volatile matter contents are used as input and the calorific value as output. The results showed that the influence of the moisture content is more dominant in determining the calorific value of fuel than volatile matter content. The performance of the calorific value predicting program also shown that the prediction error is about 0.75% to 5.2%. The obtained calorific value is well reproduced the experimental data.

Abstract

Water is the most basic need for human life. The increasing need for water shall become a social problem if it is not followed by a deep understanding by the users of water in clean water sources. The plan for taking water from the springs in Samaenre Village, Wolo District, Regency of Kolaka, by industry to meet domestic needs for industrial support facilities has the potential to cause conflict with the surrounding community. Some of the community's concerns include limited access to springs and the reduced allocation of water for the needs of residents. An effort to avoid this potential conflict is to carry out community assistance activities through Community Consultation Meetings (CCM) to increase community understanding, especially regarding the location of collection, the amount of water to be taken, the allocation of water to be taken, and the process of water extraction. The result of this activity is to increase public understanding regarding the use of water by industry and reduce public concerns regarding the impact of the use of springs on the daily conditions of residents. This community assistance enables effective communication between residents, local government, and industry. It is hoped that this service activity can continue, considering that the community has a role in supervising water extraction activities by the industry as regulated by the water resources law.  ---  Air merupakan kebutuhan paling mendasar bagi kehidupan manusia. Kebutuhan air yang terus meningkat menjadi permasalahan sosial jika tidak diikuti pemahaman mendalam oleh para pengguna air di sumber air bersih. Rencana pengambilan air dari mata air Desa Samaenre, Kec. Wolo, Kab. Kolaka, oleh industri guna memenuhi kebutuhan domestik fasilitas penunjang industri berpotensi menimbulkan konflik dengan masyarakat sekitar. Beberapa kekhawatiran masyarakat antara lain terbatasnya akses ke sumber mata air dan juga berkurangnya alokasi air untuk keperluan warga sekitar. Usaha untuk menghindari potensi konflik tersebut adalah melakukan kegiatan pendampingan masyarakat melalui Pertemuan Konsultasi Masyarakat (PKM) dengan tujuan untuk meningkatkan pemahaman warga khususnya terkait lokasi pengambilan, jumlah air yang akan diambil, peruntukan air yang akan diambil dan proses pengambilan air. Hasil dari kegiatan ini adalah meningkatkan pemahaman masyarakat terkait pemanfaatan air oleh industri dan mengurangi kekhawatiran masyarakat terkait dampak dari pemanfaataan mata air terhadap kondisi keseharian warga. Pendampingan masyarakat ini memungkinan komunikasi yang efektif antara warga, pemerintah daerah dan industri. Diharapkan Kegiatan pengabdian ini dapat terus berlangsung, mengingat masyarakat memiliki peran dalam mengawasi kegiatan pengambilan air oleh industi sebagaimana yang diatur oleh undang-undang sumber daya air.
