Implikasi Terbitnya Regulasi Tentang Pertimahan Terhadap Dinamika Pertambangan Timah Inkonvensional Di Pulau Bangka
Implication of the publication of the regulation of dynamics of tin mining on Bangka Island, it is most clearly visible are the rise of tin mining unconventional. The Central Government controls over commodities lead is so strong that they use their hands to do military protection. The local community is prohibited to mine, sell, even save them even one kilogram of matter. This condition is a precondition for the emergence of dissharmonsation in the management of lead in this area. Last issue about the rules of tin mining this regulation until now has never been resolved. So in a forum, all conflicts that erupted about tin mining will stop when the tin islands of Bangka Belitung Province have been exhausted
The Effect of Electric Flow on Decorative Krom Electroplating with Copper Base Metal Toward Corrosion Rate
In this study a decorative chrome electroplating process has been carried out with a copper base metal, metal electroplating is often used as a means to provide a thin layer on the surface of other metals or substrates using metal which has advantages in terms of property and corrosion resistance. In decorative chrome electroplating nickel and chrome are used as coatings, nickel and chrome are used as coatings because of their protective and decorative properties, protective means they can prevent corrosion and decorative because they look shiny so they look attractive. Copper metal is chosen because of its huge application in the community. This study aims to measure the corrosion rate in copper metal after a decorative chrome electroplating process based on electric current used during the electroplating process. This research is important because during the electroplating process a decorative chrome electoplating technique will be obtained in the form of modules, and the module will be used to train students to increase their skills. This research was conducted in the IKIP Mataram chemical laboratory with a time of one year. The process carried out in this study sequentially is to prepare an electrolyte solution used for electroplating, preparing the copper base metal to be free of oxide or rust, nickel coating and finally coating with chrome. From the coating process carried out then the results will be analyzed the corrosion rate by immersion in NaCl solution at a concentration of 36.05 grams / L for 336 hours, based on variations in electric current used during the electroplating process of 0.5; 1; 1.5; 2; and 2.5 Ampere, the corrosion rate results were 0.029; 0.013; 0.017; 0.022; and 0.012 mm / yr; while the copper metal which is not coated with a corrosion rate is 0.308 mm / yr. Thus it can be concluded that copper metal coated with nickel chrome will effectively resist the lowest rate of corrosion in the current given 2.5 Ampere
Pengaruh Pembelajaran Savi Berbasis Media Simulasi Interaktif terhadap Keterampilan Berpikir Kritis Mahasiswa pada Materi Elektrokimia
Characteristics of electrochemical material that contains abstract concepts. Hence often have difficulty in teaching it. An effective approach as a solution is the SAVI-based interactive learning approach of interactive simulation. Learning SAVI-based interactive media has an animation program that is able to represent abstract concepts in electrochemical materials through visualization and not illustration of the concept in narrative. The purpose of this research is to know the influence of SAVI learning approach to students\u27 critical thinking skill in electrochemical material. The type of research used is quasi-experimental research. The research design used is posttest only control group design. The sample was divided into two groups: experiment and control group. The research instrument uses critical thinking skill test through rubric. The results show that the SAVI approach has a positive effect on critical thinking skills compared to conventional methods. We conclude that the SAVI learning approach has been able to improve students\u27 critical thinking skills
Pengembangan Media Cd Interaktif untuk Meningkatkan Motivasi Belajar Siswa Kelas VII di SMPN 27 Surabaya
Penelitian ini berawal dari fenomena pendidikan, terutama di kalangan siswa sekolah menengah pertama yang saat ini masih kurang dalam motivasi belajar. Motivasi sangat penting dalam belajar untuk mencapai prestasi belajar. Kurangnya motivasi belajar pada siswa akan mengakibatkan kurang perhatian terhadap pelajaran, berbicara ketika pelajaran berlangsung dan kurang aktif bertanya. Dengan demikian akan mengakibatkan siswa tidak maju dalam proses belajar dan sulit untuk mencapai tujuan belajar dengan baik. Hal tersebut membuat pentingnya pemahaman mengenai motivasi belajar untuk siswa SMP khususnya kelas VII.
Tujuan penelitian ini adalah menghasilkan produk berupa CD Interaktif sebagai media untuk memberi pemahaman tentang meningkatkan motivasi belajar yang memenuhi kriteria akseptabilitas mencakup aspek kegunaan, kelayakan, ketepatan, dan kepatutan. Model pengembangan yang dalam penelitian ini diadaptasi dari prosedur pengembangan Borg & Gall ( 1983 ) dalam ( Setyosari, 2012 ) bahwa model ini menggariskan langkah-langkah seperti penelitian dan pengumpulan informasi awal, perencanaa,pengembangan format produk awal, uji coba awal, revisi produk, uji coba calon pengguna, rvisi produk.
Dari hasil uji coba dengan ahli materi diperoleh rerata presentase sebesar 83,43 %, hasil ahli media diperoleh 95,04 %, dan hasil uji coba dengan calon pengguna diperoleh rerata 95,33 %. Selanjutnya rata – rata dari semua presentase hasil validasi adalah 91,26. Setelah mendapatkan data tersebut dihasilkan pula kualitatif berupa saran atau masukan untuk perbaikan produk. Berdasarkan hasil penilaian tersebut, media CD Interaktif untuk meningkatkan motivasi belajar siswa telah memenuhi kriteria akseptabilitas dengan predikat sangat baik dan dapat digunakan oleh konselor dalam memberikan layanan informasi di sekolah.

Hegemoni Pemerintah terhadap Pedagang Pasar
Hegemoni merupakan dominasi atas satu kelas terhadap kelas lain disebabkan secara ideologis dan politis. Hegemoni dilakukan melalui mekanisme konsensus bukan dengan penindasan terhadap kelas sosial lain. Terdapat Hegemoni pemerintah terhadap pedagang pasar di Pasar Kite Sungailiat. Kekuasaan intelektual yang digunakan oleh pemerintah mampu mempengaruhi kesadaran pedagang untuk mengikuti kebijakan pemerintah. Pedagang yang merasa dirugikan dengan kebijakan tidak mampu untuk melakukan perlawanan. Perlawanan pedagang dapat diatasi pemerintah dengan membentuk konsensus antara pemerintah dan pedagang. Konsensus dilakukan untuk mempengaruhi pemikiran pedagang agar mengikuti aturan yang dibuat pemerintah
