Abstract

This research was conducted in PT Nusantara Tropical Farm ( PT NTF) at Jepara, Margosakti, Labuhan Ratu, East Lampung District.  The plants which were cultivated in PT NTF such as Cavendish banana, pineapple, crystal guava, and naga fruit. The irrigation being used to irrigated cavendish banana is drip irrigation method with Aries emitter type. Watering method of drip irrigation system that used for Cavendish banana is cross watering and block watering methods. The goals of this research were to determine the performance of drip irrigation line for Cavendish banana by using both kinds of watering method.  The performance indicator of irrigation system included the conveyance efficiency, the uniformity coefficient, the length time irrigation, and the amount of fuel consumption for diesel machine of a pump. The result of this research showed that the value of the conveyance efficiency of drip irrigation with cross watering method was 90,2% and 80,0% for block watering method. The uniformity coefficient on cross watering method was 87,55% and 97,10% for block watering method.  The amount of fuel consumption for 10,46 ha area with cross watering method was 29,49 l  and 40,52 l  for 10,2 ha area with block watering method.

Abstract

The level of fertility of paddy fields in Banjarrejo was decreasing, this is indicated by low rice productivity, fertilization response was leveling off, topsoil was shallow, and rice easy lodged. Fertility degradation of paddy fields occurs continuously. Factors that encourage the ongoing process of soil fertility degradation is a concept application of High External Input Agriculture (HEIA) on the cultivation of crops, especially rice. Rice straw can be used as an alternative to increase soil fertility and maintain the health of paddy field. Straw is the main product of rice cultivation in the form of organic fertilizer because its potential reaches 1.5 x grain yield. However, the potential that is available cheaply and easily and Lack of information and knowledge about straw causes many farmers not to utilize straw to the fullest. Straw is still regarded as an obstacle in tillage, where the nest mice, disease sources, and sources of dirt that must be cleaned. Farmers have not used it to be composted because many still do not have the skills to make it. State Polytechnic of Lampung has the role and responsibility to transfer technology that is beneficial to society especially in the case of making straw compost through the program of Community Service. Technical Training Composting of Rice Straw was conducted in Banjarrejo Village, Batanghari District, East Lampung Regency in April-September 2013. The use of straw compost in paddy fields can increase rice production while maintaining sustainable soil health.

Abstract

The primary channel of Argoguruh  located in Central Lampung regency. Argoguruh weir has two primary channels which is named  by Kanal One  and Kanal Two.  The decreasing performance and damage occurs with increasing age of the building. The purpose of study is to determine the performance of the primary channel Kanal One on Argoguruh weir irrigation network. Total length of the Cannal One on this study is about 9 km, which is measured from intake to distribution box on channel segmen KH2.  The method of research is conducted by direct observation in the field with determine the velocity, the dimensions of the existing primary channel and sedimentation volume. The secondary data like as the channel dimensions, discharge plans, schemes of irrigation networks, rainfall data, and climatology were collected to support for hydrologic analyst. The rainfall data and climatological data are used to calculate the water needed for irrigation , than the value of the water needed is used to calculate water discharge plan that will be used as a comparison to the existing discharge channel. The results of this study showed the water discharge in existing channel of 32.17 m3/s was able to drain the water in accordance with the discharge plan for 31.64m3/sec. The volume of sediment in the primary channel as 49344.55m3, the potential for sediment deposition during the year amounted to   471.62mm /yr, loss of water in the channel is about 0.12% and the efficiencies of primary channels is about  99.88%.Keywords: performance evaluation, primary channel, Argoguruh,

Abstract

The Bina Sarana Bakti Foundation (YBSB) implements an organic farming system, which is an agricultural management system with a terrace design with permanent beds that can ecologically (environmentally) improve land quality, provide stable and sustainable yields and income into the future. To provide water for plants so that organic farming can take place throughout the season, both in the rainy season and in the dry season, water reservoirs are built using existing water sources. Utilization of water in the cultivation of organic lettuce at the Bina Sarana Bakti Foundation is carried out with 2-level irrigation hose treatment, namely the interval of providing irrigation water for 3 days and 4 days. Data analysis used t test at 5% real level. The results showed that the theoretical amount of water for lettuce at the Bina Sarana Bakti Foundation was 714 l/bed/season which was almost the same as the actual water use of lettuce with an interval of 3 days of irrigation water including additional liquid fertilizer from rabbit urine. + water in open land in shade is 720 l/bed/season, however, it is much lower than the interval of providing irrigation water for 4 days in open land without shade, namely 4,980 l/bed/season. The production of lettuce in shade with an interval of 3 days of 30.4 kg/bed/season was much greater than the production of lettuce without shade with an interval of 4 days of irrigation water, which was only 24.7 kg/bed/season. The productivity of irrigation water for shaded lettuce with the provision of irrigation water at an interval of 3 days of irrigation is 42.22 kg/m³, much higher and more effective than lettuce without shade with an interval of 4 days of irrigation which is only 4.96 kg/m³. Keywords: irrigation time interval, lettuce plants, no shade, shade, and water productivity.

Abstract

The Bandar Lampung coastal area naturally has the potential of a tsunami hazard. Historically the coastal area of Bandar Lampung City had been hit by a tsunami with a height of 10-30 meters in 1883 when the eruption of Mount Krakatau occurred. The partial collapse of Mount Krakatau, which occurred at the end of 2018, also had a tidal wave impact as high as 1-2 meters in the Bandar Lampung coastal area. This study aims to produce Thematic Maps of Tsunami Hazard Zones in the Coastal Areas of Bandar Lampung City as a source of information for the community and stakeholders. The method used is spatial analysis with GIS through the overlay method. The result shown that eight sub district in Bandar Lampung City are prone to tsunami hazards with risk categories up to very high risk categories.

Abstract

Effort of expansion and increasing of planting intensity of upland rice in Lampung Province can be done by adding irrigation. The source of irrigation water can come from the shallow well using furrow irrigation technology. What is the furrow distance that results high water use efficiency and optimal water productivity for upland rice? This study aims: 1) to measure the amount of upland rice irrigation water usage at various furrow distances, 2) to measure plant growth and 3) determine the optimal distance of furrow irrigation. The experiment was arranged in a randomized block design with the furrow distances treatment at three levels: 60, 80, and 120 cm. Each treatment was repeated three times. The variables observed were soil moisture, the amount of irrigation water use and plant growth. Analysis of data using ANOVA at a significant difference test level of 5%. The results showed that the different furrow distance had no significant effect on the growth of upland rice. This can be caused by the soil moisture in the root zone was still in the range of readily available water, i.e. 26.9-39.4% before giving irrigation. The mean plant height at 70 days after planting in the treatment of furrow distances 60, 80 and 120 cm were 107.1, 104.1, and 106.9 cm respectively, but significantly different from the control (without irrigation) was only 86.4 cm. The number of upland rice tillers at 70 days after planting in the all treatments and control was not significantly different, i.e. in the range 20.5-25.3 stems per clump. The average irrigation water used up to 70 days after planting at the furrow distance 60, 80, and 120 cm were 733, 735, and 490 mm respectively.
