Abstract

Cleanroom in the pharmaceutical industry is needed to eliminate a wide range of contamination, due to the room around the building materials, machinery equipment production, human and others generate millions of particles that can interfere with the quality of manufactured drugs. Cleanroom in the pharmaceutical industry is based on the ISO 14644-1 standard that is in a class of E (100.000), which can be interpreted very clean conditioned room to awake from particles and microbial contamination. The number of particles in the E (100.000) class at the size of 0,5 µm limited number of 3520000 particles/m3 were obtained from the results of the design of 446771,3769 particles/m3, for a particle size of 5 µm particle number 29000 particles/m3 is obtained by 47760,7813 partikel /m3. Raw material weighing room temperature in the desain room 21 ºC and 40% RH, and the outside temperature is 32,72 ºC and 72,77% RH. The results obtained design cooling load is 17329,077 Watt, with velocity distribution of air in the airway of 0,118 m/s in air requirement of 99,615 l/s, so that the requirements for class E (100.000) according to ISO 14644-1 to the mixed flow of air velocity.

Abstract

Pada kendaraan sepeda motor, connecting rod berfungsi untuk menghubungkan piston dengan crankshaft atau poros engkol, selanjutnya meneruskan tenaga yang dihasilkan oleh piston ke poros engkol. Pada saat ini banyak beredar connecting rod imitasi dimasyarakat, dimana pada connecting rod imitasi lebih cepat mengalami kerusakan dibandingkan connecting rod asli, itu dikarenakan adanya perbedaan mechanical properties yang tidak sesuai dengan standar nya. Tujuan dari penelitian ini dilakukan untuk mengetahui perbandingan nilai kekuatan tarik pada connecting rod asli dan imitasi. Dimana dilakukan beberapa metode pengujian untuk mengetahui perbedaan dari masing – masing sample diantaranya : uji komposisi kimia, uji metallografi, uji tarik. Dari hasil pengujian material connecting rod asli dan imitasi, hasil uji komposisi kimia diketahui kadar karbon (C) pada connecting rod asli sebesar 0.176% dan pada connecting rod imitasi sebesar 0.170%. Selain itu unsur chromium (Cr) pada connecting rod asli sebesar 1.15% dan pada connecting rod imitasi sebesar 0.933%. Dari hasil uji metallografi pada connecting rod asli dan imitasi didapati fasa didominan dengan ferit dan pearlit. Hasil uji tarik pada connecting rod asli memiliki nilai rata – rata sebesar 1084.5 N/ (Mpa) dan pada rata – rata nilai kekuatan tarik pada connecting rod imitasi  sebesar 916.96 N/ (Mpa).

Abstract

Hydroelectric Power Plants (PLTA) in Indonesia have been around since 1926, and are still operating today. The Indonesian government represented by PT. PLN (State Electricity Company) will continue to maintain, operate and maintain old hydropower plants. So far, the development and development of PLTMH in Indonesia still uses consultants / contractors and its manufacturing is from overseas, even components (spare parts) are also still dependent on the technology producers themselves, the majority of which are foreign countries. Imports cannot be avoided, this results in us being vulnerable to several things, fluctuations in foreign exchange rates, and dependence on foreign producers. But with the increasing understanding of national resilience, especially in terms of national industrial independence, several national companies began to carry out reconstruction and fabrication for hydroelectric power plants. This is encouraging the author to learn to know, understand, how to plan the main parts of the Kaplan Turbine which include: runner, shaft, spiral casing, stacker, draft tube. In this plan the author focuses on calculating the main dimensions of the Kaplan Turbine. From the results of the design and calculation, the appropriate type of turbine is Kaplan Turbine as an electric generator drive in Plumbungan PLTM with installed power of 1.2 MW, maximum head of 21.16 meters and water discharge requirement of 7.68 m3 / sec. Plumbungan PLTM installation consists of turbines, turbine supporting equipment, and turbine operation aids. The turbine installation component consists of: suction pipe (penstock), turbine house (spiral casing), runner, runner shaft, shaft support bearing and draft tube.
