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.

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.

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.
