Pendeteksi Dini Terjadinya Pencurian Pulsa Pada Pesawat Telepon Pelanggan

ABSTRAK Pencurian pulsa telepon merupakan hal yang sedang marak akhir-akhir ini. Definisi pencurian pulsa adalah segala macam usaha untuk dapat menggunakan fasilitas telekomunikasi yang disebut telepon tanpa harus mengeluarkan biaya pulsa yang sudah ditentukan atau secara tidak sah. Jenis-jenis pencurian pulsa telepori sangat beragam, namun yang jelas pencurian pulsa telepon tersebut sangat merugikan berbagai fihak yaitu pelanggan telepon dan kantor sentra telepon. Pembuatan alat deteksi pencurian pulsa telepon ini dikhususkan pada kasus pencurian pulsa telepon yang paling sederhana yaitu pencurian dengan pemaralelan jalur telepon kabel milik pelanggan (kabel jalur telepon yang menuju ke pelanggan). Apabila telah terpasang nomor satuan sambungan telepon dan kabel jalur telepon yang menuju suatu tempat baik itu di rumah, kantor atau dimana saja, maka asalkan ada pesawat telepon, setiap orang dapat menggunakan jalur telepon tersebut. Tentu saja penggunaan pulsa telepon itu akan dicatat oleh kantor sentra telepon, tanpa memperdulikan siapa yang menggunakan telepon tersebut. Apabila terjadi pencurian pulsa telepon pada jalur ini, maka akan terjadi pembengkakan tagihan rekening pulsa yang akan sangat merugikan pelanggan yang jalur teleponnya diparalel oleh seseorang secara tidak sah tersebut. Pada jalur telepon terdapat tegangan arus searah (DC) sebesar 50 volt pada saat gagang pesawat telepon diletakkan (on hook), dan bila diangkat arus akan mengalir melalui pesawat telepon dan tegangan jalur akan turun menjadi 6 â 8 volt. Fenomena ini dapat dimanfaatkan untuk membuat sebuah alat pendeteksi terjadinya pencurian pulsa telepon dengan cara pemaralelan jalur telepon, dan selanjutnya alat deteksi akan memberitahukan dan mencegah pencurian pulsa telepon tersebut. Prinsip kerja alat deteksi ini adalah mendeteksi terjadinya penurunan tegangan pada jalur telepon yaitu dan 50 volt menjadi 6 â 8 volt, dimana hal ini menunjukkan terjadi pengangkatan gagang pesawat telepon dan pesawat telepon yang tersambung pada jalur tersebut (ada 2 kemungkinan, yaitu pesawat telepon pelanggan yang sah atau milik pencuri pulsa). Alat ini juga dilengkapi dengan deteksi hubung singkat dan hubung buka. Alat deteksi ini bekerja secara otomatis sehingga tidak menggangu kinerja pesawat telepon pelanggan dan kantor sentra telepon. Dan segi inovatif hal ini merupakan terobosan baru untuk mempersingkat proses pengaduan pelanggan ke kantor sentra telepon. Sedangkan segi produktifnya pembuatan alat deteksi ini mudah, relatif murah dan komponennya mudah didapatkan di pasaran, dapat diproduksi baik dalam skala industri rumah tangga maupun industri besar dan mempunyai prospek penjualan yang baik sehingga dapat mendatangkan keuntungan

ChatGPT for Teachers and Students in Science Learning: A Systematic Literature Review

In Indonesia Science education has not reached a portion that is in accordance with the needs of science education. Science learning should not only focus on knowledge but must also be balanced with application in everyday life. With this application, students will know that what they learn in science is applied and useful for life. That way, students will continue to try to experiment because of their high curiosity so that students are able to produce scientific products. Science problems are not only experienced by students, but teachers who teach science at school also have science problems they face. For this reason, Chat GPT (Generative Pre-Trainer Transformer) is used as one of the Open AI (Artificial Intelligence) innovations, a research company engaged in the development of artificial intelligence. The purpose of this research is to explain GPT Chat for Teachers and Students in Science Learning. A review is conducted on the state-of-the-art methods using the preferred reporting items for reviews and meta-analyses (PRISMA) guidelines. The results of this research show that Chat GPT has main functions, Chat GPT also has many uses for teachers and students, and science learning has five domains of science education, which must be supported by appropriate technological sophistication

Surabaya tourism management in colonial period (1906-1945)

VTV was a national tourism organization formed in 1908 to promote and organize tourism activities in the Dutch East Indies, with Batavia as its headquarter. The results of the analysis explained that Surabaya was not only a tourist destination but also a tourist sender. Main tourist objects were often visited by tourists with various backgrounds such as researchers, students, officials, and government employees. The dynamics of Surabaya's tourism were heavily influenced by major events such as the Great Depression in 1930 and World War II.VTV era una organización nacional de turismo formada en 1908 para promover y organizar actividades turísticas en las Indias Orientales Holandesas, con Batavia como sede.

Utilization of APTES-functionalized coconut waste-based cellulose microfiber/zeolitic-imidazolate framework-8 composite for curcumin delivery

With more than 7 million tons of coconut husk generated annually, this study proposes to fabricate the composite of coconut waste-based cellulose microfibers and zeolitic imidazolate framework-8 functionalized with (3-aminopropyl)-triethoxysilane (APTES-CMF/ZIF-8), which is used for curcumin uptake/release. The surface area and pore volume of APTES-CMF/ZIF-8 are found, respectively, at 247.6 m2/g and 0.21 m3/g. The morphology study also shows that the waste-based CMF possesses a uniform width at 5 e10 mm, and a length of up to several tens of microns, while the impregnated ZIF-8 has a rhombic dodecahedron shape with a particle diameter of 300e400 nm. The behavior of the curcumin uptake using APTES-CMF/ZIF-8 is elucidated via kinetics, isotherm, and thermodynamic studies. The maximum curcumin adsorption reaches 626.4 mg/g at the following condition: APTES-CMF/ZIF-8 loading (mc) ¼ 0.1% (w/w), uptake duration (t) ¼ 1440 min, temperature (T) ¼ 30 �C, and initial curcumin concentration of 1000 mg/L. This uptake follows the pseudo-second-order law and monolayer mechanism, with the fast migration of curcumin from the bulk solution to the surface of APTES-CMF/ZIF-8 as the rate-governing step. The curcumin and APTES-CMF/ZIF-8 interaction is driven by the electron exchange between both molecules. The release study of curcumin from Cur@APTES-CMF/ZIF-8 complies with the slow-first-order model. Moreover, the cumulative release is monitored at 74.2% at pH 5.5 and 47.9% at pH 7.4, signifying the pH-responsiveness of APTES-CMF/ZIF-8
