EVALUASI DEBIT DAN TEKANAN MELALUI SIMULASI KEBUTUHAN AIR PADA JARINGAN PIPA DISTRIBUSI AIR BERSIH KOTA KANDANGAN PROPINSI KALIMANTAN SELATAN
No full textAbstract: Evaluation of Flow and Pressure Using Water Requirement Simulation on Water Distribution system in Kandangan, South Kalimantan. Certain locations in service region of clean water network pipe in Kandangan city South Kalimantan profince still experience some problems. Problems are generally due to the availability of flow and pressure at distribution system. Pattern of pressure on pipe network is one of the service indicators, which are needed especially at the peak time. Study is conducted to evaluate the problems related to the condition of distribution pipe and reservoir volume to the water requirement of existing and projection situation. Projection of water requirement is made related to the pattern of location and amount of water required according to the growth of town and its people. The approach of flow requirement is conducted through two method, estimation from mean demand and from simulation on distribution network pipe. Result of simulations indicate that at existing condition, some location is still experiencing pressure degradation at the peak time. This condition can be reduced by the improvement of network system as shown from the result of future years simulation. Reservoir with the capacity of 600 m3 can serve fluctuation of daily water requirement, but in order to support improvement plan of network system, additional boosters and reservoirs are still needed in some location. Improvement of distribution system network and proper determination of reservoir volume and location will greatly assist the improvement of flow and pressure pattern at pipe network

PENGENALAN POLA SIDIK JARI RIDGE ENDING DAN BIFURCATION POINT DENGAN EKSTRAKSI MINUSI METODE CROSSING NUMBER
No full textAbstract: Biometric is a development of basic method of identification using human natural characteristics as its basic. One of the biometric system that is often used is fingerprint. Fingerprint matching system can be obtained by extraction of minutiae information. Information from minutiae extraction generated ridge ending and bifurcation. The technique coffered in this paper is based on the extraction of minutiae from fingerprint image using crossing number (CN) method to get ridge ending and bifurcation point by scanning each of ridges point. False identification of minutiae structure may be introduced into the fingerprint image due to hole and spur structure. It is necessary to test the validity of each minutiae point to eliminate false minutiae. Experiments are firstly conducted to assess how well the crossing number method is able to extract the minutiae point. The minutiae validation algorithm is then evaluated to see how effective the algorithm is in detecting the false minutiae. From experiments result using crossing number method, it can be deduced that all ridge points corresponding to ridge ending and bifurcation point have been detected successfully. However, there are a few cases where the extracted minutiae do not correspond to true minutiae points due to hole and spur structure. Applying minutiae validation algorithm is able to cancel out the false ridge endings created by the spur structure and bifurcations created by the hole structures

No full textAbstract: A natural phenomenon like change temperature, smoke concentration, air pressure, wind velocity, heavy of object, acid contents (pH), and others can, in fact, be perceived by through a Personal Computer (PC). However, both still have to be attached by an appliance linking it; that is, an appliance altering analogous signal to digital so-called Analogue to Digital Converter (ADC). Design to develop this research covers the design and layout ADC 0808 to assist the students in doing activity of interface practicum based on the control and censor. From the network, there are two controlling systems using minimum Microprocessor system 8088 and the PC. The data intakes from ADC were examined through the monitor using PASCAL language. The results of the research were gathered with an appliance ADC 0808 with the data bandwidth 8 bits using the Microprocessor 8088 mode of minimum system with the voltage ref 5.12 Volt
KENDALI KECEPATAN MOTOR INDUKSI TIGA FASA DENGAN KONTROLER PID
No full textAbstract: Speed control for three-phase induction motor with PID controller. The weakness of an induction motor is its disability to maintain the speed constantly during load changes; it will reduce the speed of induction motor. It needs a controller which enables an induction motor to maintain its speed in various set points and changing loads by determining system performance. The system is tested by referring settling point, rise time, delay time, time constant, and error state. The PID controller with 8,032 micro-controller can produce a good performance in following state: in starting phase, changing load torques, and achieving set point in t = 1.68 s, TR = 2.30 s, TS = 3.80 s, TD = 1.56 s, 1.29% error steady state (% Ess), and 1.50 Newton of load. In quick response (in mil-second), the induction motor becomes more stable, while in plant response there is no overshoot because the motor has been tied by a power brake that acts as a load
