Abstract

Electroplating by using direct current (DC) electrical energy can be obtained with a rectifier or battery. The using of electric chrome plating forms hard surfaces, high aesthetic value, corrosion resistant, wear resistant, and much in demand by the public. In West Sumatra, most of home industry products of metal creation (steel, copper, brass) are not plated yet with chrome, so that, they become less attractive. Adding the electric chrome plating to the metal products is then expected to increase the value of those products. It is essential to electroplating copper (Cu) and nickel (Ni) first before chrome (Cr). It is to improve the adesivitas and brighten the metal. The system solution used are copper sulfate (CuSO4) i = 6.68 A/dm2, t = 2 min; nickel sulfate (NiSO4) i = 3.5 A/dm2, t= 2 min; and chrome acid (CrO3) i= 5.1 A/dm2, t= 20 min. Energy source is a 12 volt battery 60 amperes. The result showed that: a) Throwing Power solution tends to decrease after the first and second plating; b) the average of layer thickness Cu: 8.54 µm, Ni: 6.65 µm, and Cr: 3.23 µm; c) good adesivitas in which there’s no cracks even in 90oand 180obending.

Abstract

Provinsi Sumatera Barat memiliki luas wilayah cukup besar yaitu sekitar 42.297,30 Km2 (4.297.300 ha), termasuk 375 buah pulau besar dan kecil. Mata pencaharian sebagian besar warga di Provinsi ini adalah sebagai pertani, buruh perkebunan dan nelayan. Diantara hasil dari sektor pertanian/ perkebunan dan perikanan adalah padi, kakao /coklat, kelapa, pisang, kopi, teh, kayu, rotan, karet, dan lain-lain) sementara itu hasil dari sektor perikanan adalah ikan, udang dan lain-lain. Para petani di daerah-daerah terpencil atau pedesaan di Sumatera Barat masih mengeringkan hasil-hasil pertaniannya dengan menggunakan metoda pengeringan tradisional yaitu penjemuran secara langsung di bawah sinaran matahari, karena tidak dapat menggunakan alat pengering nonkovensional yaitu alat pengering yang bersumberkan energi listrik dari PT PLN (Persero), sebab daerah mereka belum dijangkau aliran listrik. Pengeringan tradisional memerlukan waktu yang lama serta menghasilkan kualitas rendah. Tujuan penelitian adalah menciptakan dan menguji alat pengering hasil-hasil pertanian (biji kakao/coklat) yang bersumberkan energi surya, serta membandingkannya dengan metoda tradisional. Efisiensi termal alat pengering maksimum, minimum dan rata-rata, masing-masing diperoleh adalah : 59%, 19%, dan 34%, sedangkan intensitas matahari maksimum, minimum dan rata-rata yang diterima alat pengering, masing-masing adalah: 937 Watt/m2, 395 Watt/m2, dan 687 Watt/m2. Pada alat pengering, dengan kapasitas 48 kg biji kakao dan kadar air awal 66% untuk mencapai kadar air akhir 6% dibutuhkan waktu empat hari (18 Jam). Sedangkan menggunakan metoda tradisional, untuk waktu yang sama (18 jam) kadar air akhir hanya dapat dicapai 20%. Dari hasil pengujian dapat disimpulkan: Efisiensi termal alat pengering berbanding terbalik dengan intensitas matahari dan berbanding lurus dengan laju penguapan air bahan. Alat pengering ini lebih efisien dibandingkan dengan menggunakan metoda tradisional karena waktu pengeringan singkat.

Abstract

Pengukuran FRF (Fungsi Respon Frekuensi) memiliki peranan yang sangat penting dalam dinamika struktur. Pengukuran ini biasanya diselenggarakan untuk memperoleh kurva FRF dari sebuah sistem yang diinvestigasi. Dari kurva FRF dapat ditentukan harga frekuensi resonansi dan rasio redaman sistem. Pada pengukuran ini, sistem umumnya dieksitasi dengan palu impak atau shaker. Pengukuran FRF dengan eksitasi shaker sering dilakukan dengan metode eksitasi linear swept-sine. Makalah ini mepaparkan suatu analisa terhadap ketelitian kurva FRF yang diperoleh dari penerapan metode ini pada sebuah Sistem 2-DK (Dua Derajat Kebebasan). Ketelitian kurva FRF ditentukan dengan mengacu kepada persentase kesalahan harga magnitudo FRF dan frekuensi resonansi Sistem 2-DK yang diperoleh terhadap harga teoritiknya. Dari analisa yang dilakukan dapat disimpulkan bahwa ketelitian kurva FRF Sistem 2-DK bergantung kepada durasi eksitasi linear swept-sine yang diterapkan. Apabila eksitasi linear swept-sine diterapkan ke Sistem 2-DK dengan durasi yang lebih lama, maka persentase kesalahan magnitudo FRF dan frekuensi resonansi Sistem 2-DK yang diperoleh lebih kecil dan mendekati harga teoritiknya.
