Abstract

This study aimed to determine the effectiveness of performance irrigation at tertiary level in technical unit irrigation Metro city of Sekampung Batanghari irrigation areas.  The study was conducted at tertiary level irrigation in sekampung Batanghari irrigation areas on KBH 5 Ki 2 (upstream), KBH 6 Ki (middle), and KBH 7A Ki (downstream). The instrument that used in this research were current meter, stopwatch, Sekampung Batanghari irrigation areas map, and secondary of data.  The study was conducted using secondary data collection methods and measurement directly on the field.  The result showed that (1) the performance of irrigation in UPT Metro city irrigation were less effective that  showed from the value of the irrigation complexity is quite simple, (2) the efficiency of water delivery at tertiary level irrigation in metro city that classified as unoptimal, there is 81,23 % and still under the preliminary draft, (3) the overall irrigation performance in the tertiary level of UPT Metro city still low. Keywords: effectiveness of performance, irrigation, Metro city, Sekampung Batanghari

Abstract

Food security improvement program is directed to be able to fulfil the food needs of people in the country from national food production.  One of the national foodstuffs that is strived to be provided throughout the year is rice.  The purpose of this study to obtain flooding height and type of fertilizer that can provide maximum M70D rice production and improve soil fertility.  This study uses a completely randomized design (CRD) arranged in factorial 2x4 with three replications.  The first factor is the application of water level consisting of 4 levels including (2 cm, 3 cm, 4 cm, and 5 cm).  The second factor is the application of fertilizers consisting of ghally organic and Urea, TSP, and KCL fertilizers.  The results showed that in general the treatment of 4cm flooding height and Urea, TSP, KCL fertilizer gave the best results on plant height, number of tillers, number of productive tillers, and number of rice grains.  Meanwhile the treatment of ghally organic fertilizer can increase nutrients in the soil and rice plants.  Ghally organic fertilizer has more role to improve soil structure and more efficient on water consumption of M70D rice plants.  M70D rice plants cannot be applied by ghally organic fertilization using the spread method, because ghally organic fertilizers based on aerobic and anaerobic microba which can not work optimally in flooded conditions. Keyword: Fertilizer, Flooding Height, Nutrient, Paddy.
