Abstrak:Tulisan ini mengungkap persoalan yang terjadi di kalangan mahasiswa, seiring derasnya arus globalisasi yang menerpa aktifitas mahasiswa yang semakin lama semakin mengkhawatirkan, sehingga mengarah pada budaya konsumerisme. Budaya ini menjadi ideologi dan menjadi tuntutan gaya hidup mahasiswa yang semakin tidak terkontrol. Sekalipun mereka menyadari bahwa perilaku konsumtif merupakan sikap negatif, yang kurang bisa diterima dalam hubungan sosial maupun agama, terlebih dalam Islam. Karenanya, penelitian ini berupaya untuk menjelaskan: (1) Bagaimana perilaku budaya konsumerisme dan teori kebocoran di kalangan mahasiswa? (2) Bagaimana solusi ekonomi Islam melihat kondisi menjamurnya budaya konsumerisme tersebut? Penelitian ini dilakukan dengan asumsi bahwa sejumlah mahasiswa berperilaku konsumsif yang mengarah kepada budaya konsumerisme. Hasil penelitian ini memperlihatkan bahwa perilaku budaya konsumerisme, yang kemudian peneliti sebut dengan kebocoran mahasiswa, sudah sangat mengkhawatirkan. Dalam hal ini, ekonomi Islam menawarkan konsep-konsep konsumsi, seperti tidak melakukan isrâf.Kata Kunci: Budaya konsumerisme, teori kebocoran, ekonomi Islam, mahasiswa Abstract:This paper reveals problems that occur among university students, as the swift currents of globalization that hit the activities of university students that increasingly worrying and leading to a culture of consumerism. This culture becomes an ideology and a lifestyle demands of increasingly uncontrollable students. Even if they realize that consumptive behavior is a negative attitude that is less acceptable in social relationships and religion, especially in Islam. Therefore, this study seeks to explain: (1) How does the behavior of the consumerism culture and the leakage theory among university students? (2) How does the solution of Islamic economy sees the condition of the mushrooming of the consumerism culture? This research was conducted on the assumption that the number of university students behave consumptive that lead to the culture of consumerism. This study shows that the behavior of the consumerism culture, then I call the leakage of university students, is very worrying. In this case, the Islamic economy offers the concepts of consumption, as not doing isrâf.
This study aims to describe the creative thinking process of students in solving math problems in terms of differences in gender. This study qualitatively examines the creative thinking process of sixth semester students of mathematics education at the Faculty of Science and Technology, UIN Walisongo. The data collection techniques used in this study were questionnaires, tests, interviews and completed with documentation. The data analysis techniques in this research are data reduction. The data analysis technique in this research is data reduction and data validity by using time triangulation, namely by looking for the suitability of interview data which originates from the problem of two similar questions. The results showed that gender differences did not significantly affect students’ creative thinking abilities. Male subjects need stimulation of questions from researchers to compile information correctly and precisely. Male and female subjects monitored the problem-solving process well, but both had not yet carried out an evaluation process.
AbstrakAir merupakan kebutuhan yang sangat vital bagi kehidupan manusia. Permasalahan yang timbul yaitu sering dijumpai bahwa kualitas air tanah maupun air sungai yang digunakan masyarakat kurang memenuhi syarat sebagai air minum yang sehat bahkan di beberapa tempat bahkan tidak layak untuk diminum. Untuk menanggulangi masalah tersebut, salah satu alternatif yaitu mengolah air tanah atau air sumur sehingga didapatkan air dengan kualitas yang memenuhi syarat kesehatan dengan merancang sebuah alat filtrasi air. Pada penelitian ini dirancang sebuah alat filtrasi air skala rumah tangga dengan metode pengontrolan pada aliran air pada proses filtrasi. Metode kontrol yang digunakan yaitu fuzzy_PID. Kontrol fuzzy_PID digunakan untuk mengatur debit aliran air yang masuk kedalam filter dengan mengatur kecepatan pompa air yang dipengaruhi oleh kejernihan air hasil filtrasi. Fuzzy logic digunakan untuk menghasilkan parameter Kp, Ki, Kd pada kontrol PID dengan input berupa error dan perubahan error. Sensor yang digunakan pada penelitian ini ialah sensor kejernihan 1, sensor kejernihan 2 dan sensor flowmeter. Sensor kejernihan 1 digunakan untuk mendeteksi nilai kejernihan air input dan sensor kejernihan 2 digunakan untuk kejernihan air output. Kemudian sebagai pusat kendalinya yaitu arduino uno. Pada penelitian yang dilakukan diketahui bahwa kecepatan aliran air dapat mempengaruhi nilai kekejernihan air yang dihasilkan pada proses filtrasi. Ketika kejernihan air output dibawah setpoint, maka kecepatan aliran air akan diperlambat sampai kejernihan air output sama dengan setpoint. Pada percobaan setpoint 94 %, Kecepatan debit aliran air berubah dari 872 (Liter/jam) menjadi 752 (Liter/jam) pada saat terjadi perubahan kejernihan air output filtrasi dari 94 % menjadi 93%.Kata kunci: Arduino Uno, Fuzzy_PID, Kejernihan, Sensor Flowmeter. AbstractWater is a vital requirement for human life. The problems that arise are often found that the quality of ground water and river water used by people less qualified as healthy drinking water even in some places even unfit for drinking. To overcome the problem, one alternative is treating groundwater or well water to obtain a water quality that meets the health requirements to design a water filtration apparatus. In this study designed a tool household water filtration with a method of controlling the flow of water at the filtration process. The control method used is fuzzy_PID. Fuzzy_PID control is used to regulate the flow of water into the filter by adjusting the speed of the water pump is influenced by the clarity of the water filtration results. Fuzzy logic is used to generate parameters Kp, Ki, Kd on PID control input of the error and error change. The sensor used in this study is the clarity of the sensor 1, sensor 2 and sensor flowmeter clarity. Clarity Sensor 1 is used to detect the value of the input water clarity and lucidity sensor 2 is used for water clarity output. Then as the control center that is arduino uno. In the study conducted in mind that the speed of water flow may affe...
