Abstract

Paper ini membahas cara lain mengukur induktansi sendiri menggunakan tahanan referensi, voltmeter, amperemeter dan perhitungan dengan hukum cosinus suatu sudut antara dua buah vektor tegangan yang diukur. Cara yang biasa digunakan menggunakan alat ukur khusus: induktansi meter. Dengan cara ini kita dapat memanfaatkan alat yang biasa ada di laboratorium dasar rangkaian listrik, sehingga tidak memerlukan alat ukur khusus yang cukup mahal. Keakuratan hasil hanya dipengaruhi oleh frekuensi sumber. Dalam hal ini frekuensi sumber dianggap tidak berubah.

Abstract

Usaha diversifikasi katalis berbasis besi untuk proses pencairan batubara telah dilakukan, salah satunya adalah red mud yang telah diaktivasi. Red mud adalah produk samping dari proses Bayer pembuatan alumina dari bijih bauksit. Katalis tersebut diperoleh melalui aktivasi red mud dengan asam (HCl atau H3PO4), masing masing dengan variasi pH yaitu 5, 8 dan 11. Red mud aktif ditunjukkan dengan menurunnya kandungan natrium. Kinerja katalis yang dihasilkan diuji melalui proses sulfidasi, yang ditunjukkan dengan terbentuknya senyawa aktif pirotit, dan proses pencairan batubara dengan menghitung  persen konversi batubara cair yang dapat dihasilkan. Hasil penelitian menunjukkan bahwa kandungan natrium dalam red mud dapat diturunkan sebesar 88,25% dan 88,74% dari 4,34% menjadi 0,51% dan 0,49% setelah mengalami perlakukan dengan asam HCl 35% pada pH 8. Sedangkan bila menggunakan asam H3PO4 35%, kandungan natrium dalam red mud tidak mengalami penurunan yang berarti. Hasil uji sulfidasi terhadap red mud tanpa aktivasi diperoleh ukuran kristal pirotit sangat kecil, hal ini disebutkan karena belum sempurnanya pembentukan kristal pirotit. Sedangkan dari red mud yang diaktivasi dengan HCl pada pH 8 dan H3PO4 pada pH 11 berturut-turut menghasilkan ukuran kristal pirotit sebesar 35 nm dan 30 nm; syarat ukuran kristal pirotit yang baik untuk katalis pencairan batubara adalah<40 nm. Persen konversi produk batubara cair dengan menggunakan katalis red mud tanpa aktivasi dan red mud aktivasi HCl pada pH 8 berturut-turut menghasilkan 72,34% dan 84,76% batubara cair. Hasil ini belum optimal dibandingkan terhadap jenis katalis yang telah dikenal seperti limonit. Sehingga masih diperlukan pengoptimalan proses aktivasi red mud. Kata Kunci : red mud, aktivasi, katalis, konversi

Abstract

Motor Induksi tiga fasa merupakan salah satu jenis motor yang paling banyak digunakan pada industri. Motor ini biasanya yang menjadi perhatian khusus adalah pengendalian kecepatan. Pengendali yang digunakan biasanya hanya pengendali Proportional Integral Derivative (PID). Namun terkadang pada proses kontrol, pengendali lain seperti Proportional Integral (PI) dan Proportional Derivative (PD) juga sering digunakan. Penelitian ini akan membandingkan pengendali-pengendali tersebut dalam proses pengendalian kecepatan pada motor induksi tiga fasa saat berbeban dan tanpa beban. Untuk memudahkan proses pengendaliannya, digunakan Supervisory Control and Data Acquisition (SCADA) yang memiliki kemampuan dalam mengakuisisi data dan monitoring. Dalam pengujiannya didapatkan bahwa pada pengendali terbaik yakni PID dimana error steady state kecil, settling time cepat dan tetap stabil meskipun terdapat perubahan beban.  Pengendali PID ini memiliki parameter KP  = 2,  Ti = 1, Td =3. Sedangkan data yang ditampilkan oleh sistem SCADA dapat dikatakan baik dan valid, dimana persentase penyimpangan untuk data kecepatan sebesar 0,1%.

Abstract

Raudhatul Ulum Meranti Islamic Boarding School is a da'wah institution that was established to educate the generation of Muslims in Indonesia, especially in West Kalimantan. Raudhatul Ulum Meranti Islamic Boarding School was founded in 1896 in a village called Meranti Village, Sungai Ambawang District, Kubu Raya Regency. The curriculum applied by the pesantren initially only adhered to the classical system (teaching the yellow book) and developed into a curriculum sourced from the Ministry of Religion (KEMENAG). The aim of developing the area of Raudhatul Ulum Meranti Islamic Boarding School is to make facilities suitable for the modern education system. The design location is on Jalan Muhajirin, Kampung Meranti, Puguk Village, Sungai Ambawang District, Kubu Raya Regency. The stage method in this design starts from the Idea Stage, Data Collection, Analysis, Synthesis, Pre-Design and Design Development. The concept of Natural Pro Rate is applied so the areas that are still green do not have to build by destroying nature in the area, but rather organize and maintain the natural conditions in order to remain green. The results of the development design at Raudhatul Ulum Meranti Islamic Boarding School can make the mosque building as the heart of the area. Worship and educational facilities are made with Islamic nuances by combining ornaments in the building and creating a separate area between the male and female students.

Abstract

Salah satu cara paling umum untuk mengontrol kecepatan adalah dengan menggunakan sensor enkoder Data yang dihasilkan akan ditampilkan di komputer atau laptop Anda. Saya tahu pengamatan mereka. Semakin banyak motor memiliki biaya perawatan yang lebih rendah selain efisiensi, torsi, kecepatan dan variabilitas. motor DC ini memiliki proses pergantian yang lebih cepat dan biaya perawatan yang lebih rendah, yang menyebabkan sikat menjadi percikan api dan cepat menjadi rusak. Rotor terbuat dari kumparan dan diinduksi oleh medan magnet berputar stator, yang menyebabkan arus listrik di rotor. Kecepatan putaran rotor jauh lebih lambat daripada kecepatan putaran medan magnet stator. Akibatnya motor induksi cenderung kurang efisien dibandingkan motor DC kecepatan tinggi, bisa fluktuatif, dan biaya perawatannya lebih rendah, sehingga digunakan motor DC brushless atau biasa dikenal dengan motor BLDC.
