Abstract

Pendidikan adalah usaha yang dilakukan secara sadar dan terencana untuk mewujudkan suasana belajar dan proses pembelajaran sehingga peserta didik secara aktif dapat mengembangkan potensi dirinya yang diperlukan bagi dirinya masyarakat, bangsa dan negara. UPN ”Veteran” Jatim atau UPN V JT atau Universitas Pembangunan Nasional “Veteran” Jawa Timur, berlokasi di Surabaya merupakan salah satu perguruan tinggi negeri di Indonesia yang berdiri sejak 5 juli 1959. Pada Universitas Pembangunan Nasional “Veteran” Jawa Timur akan menambah program studi yaitu kedokteran. Metode penelitian yang digunakan adalah simulasi sistem dinamis, sebagai metode untuk membentuk suatu model simulasi computer, untuk membantu mempelajari kompleksitas dinamis, mengerti sumber resistensi kebijakan, dan mendesain kebijakan yang lebih efektif. Dari hasil simulasi kebijakan menggunakan software vensim yakni jumlah dokter cenderung meningkat. Jika tidak ada kebijakan penambahan program studi kedokteran, jumlah dokter pada tahun 2024 adalah 4351.96 ribu. Sedangkan jika terdapat kebijakan pembangunan program studi kedokteran, maka jumlah dokter pada tahun 2024 adalah 4419.86 ribu. Dan jumlah kebutuhan dokter cenderung menurun. Jika tidak ada kebijakan penambahan program studi kedokteran, jumlah kebutuhan dokter pada tahun 2024 adalah 410.917 ribu. Sedangkan jika terdapat kebijakan pembangunan program studi kedokteran, maka jumlah kebutuhan dokter pada tahun 2024 adalah 409.74 ribu. Kata Kunci: Jumlah kebutuhan dokter,Software Vensim,Sistem dinamis, desain kebijakan.

Abstract

Clay is silicate frame-based mineral praticle with a diameter of less than 4 micrometers, clay contains fine fused silica and aluminium. The development of clay as an alternative adsorbent is very possible because the clay has a large surface area, high porosity, and high abundance in nature and also relatively inexpensive compared to other adsorbents. The purpose of this study was to determine the ratio of SiO₂/Al₂O₃ content in activated clay. Clay was activated by using hydrochloric acid (HCl) with variable time and concentration of Hydrochloric Acid. Variable concentrations of hydrochloric acid used were 1N, 2N, 3N, 4N, 5N 1000 ml and time variables were 1 hour, 1.5 hours, 2 hours, 2.5 hours, and 3 hours. The best ratio results were shown at 5 N hydrochloric acid (HCl) concentration with 3 hours activation time of 12,26%.

Abstract

Particle board consists of sheets of material made from wood chips or materials containing lignocellulose such as flakes and strands to be joined by using a binder and by providing various aids such as heat and press. The purpose of this research was to study the physical value (moisture content, thickness development, and density) and mechanical properties (elasticity and tensile strength) and its conformity to SNI. Particle board making in this study was a mixture of wood powder with plastic Low Density Polyethylene (LDPE) with a composition according to variable pressure pressed with 25 kg/cm2 with long pressing at the required temperature for an hour and added with 30 minutes of packing. The variables used were temperature and material composition. The making of particle board from cassava powder and plastic LDPE based on air content test, thickness development, and straight tensile strength were appropriate to SNI. The best results obtained in this study was the composition comparison of plastic LDPE: wood powder (80; 20) with a temperature of 160℃ with a moisture content of 1,2027%, thickness development of 9.217 %, density of 0,831 g/cm3, MOE of 21304,600 kgf/cm2, and perpendicular tensile strength of 31,094 kgf/cm2. This particle board passed all tests and have the average value and better characteristics compared to others.
