Abstract

Dewasa ini, perkembangan teknologi terus mengalami kemajuan, hal ini terlihat semakin banyaknya peralatan elektronika yang digunakan dalam keperluan sehari - hari, salah satunya dalam ranah ilmu konversi energi listrik, yaitu DC line filter pada catu daya. Filter catu daya merupakan alat perubahan tegangan listrik yang dapat merubah listrik AC menjadi listrik DC yang dilengkapai dengan filter sehingga menghasilkan tegangan DC yang lebih baik. Telah banyak penelitan – penelitan yang dilakukan dalam rangka mendapatkan tegangan DC yang baik dengan memperkecil faktor riak yang dihasilkan. Namun teknik baru dilakukan dengan membuat alat yang dapat membandingkan berbagai jenis filter catu daya yang ada antara lain catu daya tanpa filter, catu daya dengan filter C dan catu daya dengan filter RC.

Abstract

Perencanaan strategis mencakup tujuan jangka panjang dan seringkali melibatkaninvestasi yang sangat besar. Oleh karena itu, suatu perencanaan yang baik diper-lukan agar tujuan rantai pasok tercapai untuk memenuhi kebutuhan pelanggandan juga untuk meraih keuntungan bagi seluruh rantai pasok. Secara alami, keti-dakpastian adalah hal yang tidak dapat dihindarkan terutama sekarang ini ketikalingkungan bisnis semakin kompetitif dan penuh perubahan. Untuk menghadapiketidakpastian ini, pelaku bisnis dan perencana rantai pasok harus memiliki suatualat atau strategi agar rencana strategis perusahaan menjadi handal. Satu rencanadisebut tangguh (robust) apabila mampu menghadapi ketidakpastian, yaitu tetapberperformansi stabil meskipun beberapa parameter perencanaan berubah-ubah.Penelitian ini membahas integrasi transportasi dan produksi dalam rantai pasokdi level strategis sehingga rencana yang dihasilkan menjadi tangguh menghadapibeberapa perubahan pada parameter perencanaan. Suatu formulasi dan modeloptimasi diusulkan untuk menangani permasalahan yang timbul akibat ketidak-pastian permintaan dan ketidakpastian jalur transportasi.i

Abstract

In general, an organization’s life cycle consists of 4 phases. Those phases are birth, growth, mature, and decline. In order to optimize an organization’s income, it should retain its growth and mature phases as long as possible. There have been quite a number of growing SME in West Java, however merely a fraction of them who is able to survive the growth phase. In order to survive, one of the main issues is to keep the workers motivated to achieve a good performance.There have been several theories explaining motivation, including the one offered by Herzberg. According to Herzberg, there are two groups of factors that contribute to motivation. They are motivator and hygiene factors. A person’s dissatisfaction may be eliminated by providing the hygiene factors, while a person’s satisfaction may be enhanced by providing the motivator factors. In this research, those factors are grouped further into 6 categories based on Kano model. Based on the categorization, it is clear which factors affect a person’s job satisfaction. In the context of SME, they would be able to prioritize the factors that they need to motivate the workers, keep the workers satisfied, and furthermore survive the growth phase.

Abstract

Linear Programming Model consists of one objective function and at least one constraint. The parameters in the objective function are called objective function coefficients. Objective function coefficients represent the contribution of one unit of its corresponding decision variable to the objective function value. The exist objective function as well as its constraints in the linear programming model are characterized as crisp. Such assumptions are often considered as unrealistic. This research models and solves the Linear Programming Model in the case where objective function coefficients are in the form of triangular fuzzy number and the constraints are fuzzy as well. Abstract in Bahasa Indonesia : Model Pemrograman Linear (MPL) memiliki sebuah fungsi objektif dan satu atau lebih kendala. Pada fungsi objektif terdapat parameter yang disebut koefisien fungsi objektif (objective function coefficients). Koefisien fungsi objektif menggambarkan kontribusi satu satuan variabel keputusan terhadap nilai fungsi objektif. Koefisien fungsi objektif yang selama ini dikenal dalam pembahasan MPL bersifat tegas (crisp)., demikian pula dengan kendala. Tulisan ini membahas suatu pendekatan terhadap perumusan dan penyelesaian MPL dalam hal koefisien fungsi objektifnya berbentuk bilangan kabur segitiga (triangular fuzzy number) dan kendalanyapun bersifat kabur. Kata kunci: model pemrograman linear, parameter pemrograman linear, bilangan kabur, koefisien fungsi objektif, bilangan kabur segitiga, kendala kabur.

Abstract

Competition in the higher education, especially private higher education (PTS) in the digital era, is becoming increasingly tough. In order to achieve the number of prospective new students, various methods are used so that the target for admitting the number of new students can be achieved in each new academic year. Providing a scholarship program is one way to attract the prospective new students. The awarding of a scholarship program must consider various possibilities such as the seriousness or commitment of the prospective new student. Refusal to grant scholarship programs can occur and become an obstacle for achieving the target. The prediction model through machine learning using some variables such as high school’s name, high school “category”, province or area of high school located, focus of specialization in high school, high school’s grade, type of parents income, and selected major of study in higher education. All of those variables will provides the probability values that will become an indicator that can be used to prioritize requests for scholarship program applications by taking into account the factors of acceptance or rejection from prospective students. Currently there is no measurement with accuracy of acceptance or rejection from prospective students. The purpose of this research is to build and compare machine learning models such as Logistic Regression, Artificial Neural Networks, Support Vector Machines, Decision Trees, Naïve Bayes, and K Nearest Neighbors so that a machine learning model is obtained that has the best predictions for awarding scholarship programs. The result of this research is that the Logistic Regression model has the highest model average accuracy value (62,05%) from training data compared to others. The highest accuracy of Logistic Regression model (62,29%) achieved based on the testing data. The highest AUC value (0,818) generated by Logistic Regression model which means the model is able to do the classification categorized “Good Classification” compare to other models.
