Abstract

Irrigation efficiency is defined as ratio between the total of water supplied is reduced water losses with the total supplied. Irrigation water losses that occurs during water supplying mainly caused by seepage in wet canal section, evaporation (generally insignificant) and operational losses dependent on irrigation water management system. The purposes of this research is to analyze the magnitude of the efficiency of Irrigation network in Malaka. This research is done on the primary, secondary and tertiary canal. The efficiency of Malaka irrigation network is analyzed by the method of water discharge in – water discharge out. The data used in this analysis is the primary data such as flow rate data by current meter for primary and secondary canal and flow rate data by a float for tertiary canal. In addition to the primary data also used secondary data from the nearest Climatological Stasiun. The results of analysis, water losses caused by evaporation is very insignificant, so water losses is caused by physical canal factors with smallest water loss occurred at BBKi.1outflow-BBKi.2inflow canal is 3,541% and most of loss that occured at BNM.6outflow-BNM.7inflow canal is 0.066 m3/sec. The average efficiency of the whole network of irrigation at Malaka Kiri 84.371% with primary canal efficiency is 90.343%, and secondary canal efficiency is 82.878%.

This research aimed at measuring level of performance in the form of service capacity at Veteran St., as it was affected by the existence of Lipo Plaza. The affect of the business center on service capacity of some sections of roads would be expressed in the comparisons of traffic volume, traffic capacity and degree of saturation (DS) before its existence, to the same after it had existed. Result of analysis in this research showed that there was a change in traffic volume, either increasing or decreasing. Increase of traffic volume occurred at segment of Veteran St., Patung Kirab area, Nostalgia Park area, Ina Bo’I, W.R. Monginsidi St., and Perintis Kemerdekaan St., each in value of 81.5 pmu/h, 35.97 pmu/h, 17.41 pmu/h, 8.83 pmu/h and 38.94 pmu/h respectively; whereas decrease of the same occurred at road segment to the back of Ruko Oebobo, in the value of 1.37 pmu/h. Service level of Veteran St. was proved to be still adequate despite the dercrease of DS at Veteran St., Patung Kirab area, Nostalgia Park area, Ina Boi, W.R. Monginsidi St, and Perintis Kemerdekaan St., each in the value of 4.05%, 2.07%, 0.75% 0.34% and 2.86 respectively. There was still location with decreasing DS that is the segment of road to the back of Ruko Oebobo, namely 0.13%. Observation also showed that there exists potency for traffic jam, therefore measures for prevention was recommended, such as installing warning traffic-light at intersection of Veteran St., Nostalia Park and Ruko Oebobo, and temporary road separator at Veteran St. These could as well prevent traffic crash at conflict points.
