Rancang Bangun Prototipe Kapal Elektrik Dengan Sistem Kendali Jarak Jauh
Get PDF Sejalan dengan penguatan untuk pengawasan wilayah yang sangat luas serta terdiri atas pulau – pulau, diperlukan media transportasi perairan dengan dilengkapi sistem peralatan yang mampu mengatasi segala bentuk ancaman maupun gangguan yang dapat terjadi setiap saat. Untuk memenuhi upaya tersebut maka dilakukan penelitian dan pengembangan prototipe kapal listrik yang tahan di segala medan. Dalam pembuatan prototipe kapal listrik ini menggunakan sistem penggerak elektrik. Sistem penggeraknya menggunakan Motor DC Brushless dengan sumber tenaga dari baterai. Energi listrik ini dapat menjadi alternatif pengganti energi fosil. Sistem kendali pada prototipe kapal listrik ini menggunakan sistem kendali jarak jauh. Proses pengukuran kecepatan kapal dilakukan dengan menggunakan bantuan sensor Accelerometer dan GPS pada smartphone. Kedua sensor ini di akses dengan menggunakan aplikasi NMEA Tools. Prototipe kapal listrik berhasil dikendalikan dari jarak jauh dengan uji garis lurus sejauh 50 meter pengukuran mencapai kecepatan rata-rata 23,16 Knot, uji gerak zigzag lintasan berukuran panjang 16.910 meter penguuran kecepatan rata-rata 3.1 Knots, dan uji gerak melingkar dengan radius putar adalah 2.638 meter dengan rata rata kecepatan kapal 4.25 Knots
KARAKTERISTIK BRIKET LIMBAH KULIT PISANG PEREKAT TEPUNG TAPIOKA
Get PDFKulit pisang merupakan limbah rumah tangga yang sangat banyak di hasilkan, selain limbah rumah tangga limbah kulit pisang mudah ditemui di kedai gorengan yang ada di kota Balikpapan. Limbah kulit pisang dapat digolongkan sebagai limbah biomassa, sehingga dapat dimanfaatkan untuk dibuat menjadi bahan baku briket. Limbah kulit pisang yang digunakan yaitu jenis kulit pisang kepok. Proses pembuatan briket dimulai dengan pembuatan bioarang limbah kulit pisang, limbah kulit pisang melalui proses pembakaran menggunakan tungku hingga berubah menjadi bioarang. Limbah kulit pisang yang telah berubah menjadi arang kemudian dihaluskan menjadi serbuk dengan melakukan penyaringan menggunakan mesh 50 dan mesh 80. Setelah dilakukan penghalusan bioarang kemudian dilakukan pencampuran dengan menggunakan perekat tepung tapioka. Variasi dari perekat tepung tapioka yaitu 5% dan 15%. Briket yang telah jadi akan dilakukan pengujian di laboraturium untuk mengetahui kadar kalori, kadar abu, dan kadar air. Hasil penelitian briket terbaik yaitu dengan mesh 50 dan prosentase perekat 15%, yaitu dengan kadar nilai kalori sebesar 5216,48 kal/g, kadar abu sebesar8,42%, kadar air sebesar 7,9%. Dapat disimpulkan briket dengan bahan baku limbah kulit pisang dapat dijadikan sebagai energi terbarukan dengan terus melakukan perbaikan dari komposisi bahan baku briket.Kata kunci: Briket, limbah kulit pisang, nilai kalor, kadar abu, kadar air ABSTRACTBanana peels are a household waste that is produced a lot, apart from household waste, banana peel waste is easily found in fried food shops in the city of Balikpapan. Banana peel waste can be classified as biomass waste, so it can be used to make raw materials for briquettes. The banana peel waste used is the Kepok banana peel type. The process of making briquettes begins with making biochar from banana peel waste. The banana peel waste goes through a burning process using a furnace until it turns into charcoal. The banana peel waste that has been turned into charcoal is then ground into powder by filtering using mesh 50 and mesh 80. After grinding the biochar, it is then mixed using tapioca flour adhesive. Variations in tapioca flour adhesive are 5% and 15%. The finished briquettes will be tested in the laboratory to determine the calorie, ash, and water content. The best briquette research results were with a variety of mesh of 50 and an adhesive percentage of 15%, namely with a calorific value of 5216.48 cal/g, ash content of 8.42%, and water content of 7.9%. It can be concluded that briquettes made from banana peel waste as raw material can be used as renewable energy by continuing to improve the composition of the briquette raw material.Keywords: Briquettes, banana peel, calorie value, ash content, water conten
