POLA ALIRAN DAN PENURUNAN TEKANAN PADA ALIRAN DUA FASE GAS-CAIR MELEWATI PENGECILAN PIPA SECARA MENDADAK
No full textAbstract: The Flow Patterns and Pressure Drop on Two-Phase Gas-Liquid Through Sudden Contraction. The aim of this research is to describe the flow patterns and pressure drop on two-phase gas-liquid through sudden contraction. It limits the contraction coefficient (S) into three variants: S = 0,8; S = 0,6 and S = 0,4. For describing the distribution and pressure drop, it uses two-dimension line graphics. The result shows that (1) the flow pattern in horizontal contraction tends to shape separated flow, meanwhile in vertical contraction it tends to shape homogenous inflated flow; (2) the pressure on pipe surfaces before contraction surface is bigger than those of ducting axis; (3) the pressure on pipe surfaces after contraction surface is smaller than those of ducting axis; (4) the pressure drop turn into bigger on bigger mass flux and mixture quality; (5) the pressure drop in homogenous flow is bigger than those of separated flow; and (6) the difference average between calculated and theoretical pressure drop is less than 20%

PROTEKSI MOTOR INDUKSI TIGA FASA TERHADAP EMPAT JENIS GANGGUAN
No full textAbstract: The protection of three-phase induction motor against four types of disturbance. Generally, the installation of three-phase motor only uses protection system of fuse and MCB. However, the usage of fuse and MCB is still limited; due to the availability of another system that cover much more disturbances. This research sets out to develop the protection of three-phase induction motor by using computerization and electro-mechanics. It used experimental method with the stages as follows (1) designing protection circuit, (2) testing the circuit, (3) analyzing the result, and (4) redesigning the circuit if necessary. The outcome of this research is the protection tools of induction motor installation, which is able to operate over various types of disturbance

PERANCANGAN CONTROLLER LOGIKA FUZZY SEBAGAI PENGENDALI RANGKAIAN SWITCHING FILTER AKTIF UNTUK MENGELIMINASI HARMONISA PADA TRANSFORMATOR DISTRIBUSI
No full textAbstract: This research designs controller of logic of fuzzy to control network of switching of at active filter so that can inseminate tension of compensation by precision. This matter can be happened because controller of have logic to of fuzzy work pursuant to signal error and delta of error of among pure signal and signal which distortion by trouble harmonic. Plant to be designed consisted of by a transformer of distribution with two bobbin of primary and one secondary bobbin se. Signal output of transformer which the distortion will be compared to by signal identify to get signal error. This signal error will be used as input for controller. Controller of logic of fuzzy used to arrange wide of pulse to be inseminated by pursuant to signal error. Result analysis of simulation is conducted in the situation steady-state transformer, that is start t = 0.06s. This research conclusion is the following: (1) filter active designed by inseminating compensation tension of through transformer can degrade Total Harmonic Distortion (THD) until 24.995% for trouble harmonic of third and for-5, and 15.495% for trouble harmonic of second and fourth; and (2) existence controller logic fuzzy earn more improve repair waveform, so that can degrade THD until 4.471% for trouble harmonic of third and for-5, and 6.638% for trouble harmonic of second and fourth compared to by output transformer of before controlled

STABILITAS CHECK DAM DI ARBORETUM DESA SUMBER BRANTAS
No full textAbstract: The stability of check-dam in arboretum of Sumber Brantas village. Sumber Brantas water sources area is arboretum territory which has to be maintained as conservation either for technical or vegetation (plants cover) by sustainable development. Arboretum territory is made as asylum in irrigation system district of Brantas River. This research discusses technical conservation activity to build the check dam in conserving the area. Check dam is built dimensionally by using HEC-RAS Program to get safe and stable dimension for rolling, shifting and piping of Sf > 1.5, and based on hydrologic analysis to get maximum flood discharge of 48.01 m3second-1. Hydraulic analysis is used to get water level profile and pressure for the dam body. Stability of the structure will be controlled by construction load (weight of check dam) and its fully sediment storage condition. The result of this research shows that the safe and stable dimension for check dam are as follows: 28 meter of width; 3 meter of main height; 1.5 meter of sub-height; 10 meter of stilling basin length (Main Dam–Sub Dam)
