<![CDATA[Shoreline change is a natural process caused by the transported sediment generated by nearshore current to preserve the mass rates. Shoreline change can be a shoreline loss called abrasion as well as shoreline expansion due to sedimentation called accretion. Abrasion and accretion phenomenon can be regarded as a threat if they cause damage or potentially disrupts human activity. Identification of land use as well as geographical and physical condition of a region can be approached by satellite image analysis. This research uses Landsat Satellite imagery to observe shoreline changes based on the position of shoreline recorded through satellite images of 2004, 2010, and 2016. The image of one period overlapped with other period images is used to calculate the increment or decrease of shoreline occurring at a particular location. The results of this study will show the trend of increasing or decreasing the shoreline based on certain time and position]]>

<![CDATA[Shallot is superior vegetable commodity in which the demand has a tendency to increase. The growth of demand for commodity is in line with the growth of population in Indonesia. Shallot is included in 7 (seven) basic foodstuffs targeted by Ministry of Agriculture in Indonesia. The need of shallot is supplied by Central Java, East Java, West Java and West Nusa Tenggara. Shallot commodities in Indonesia heavily depend on the season, the government makes a regulation about shallot import for maintaining stability of price. To anticipate the occurrence of imports, the government is focused on inviting local governments to create a farming center of shallot. Lampung Province is one of the provinces that has suitable natural resources for shallot farming. The purpose of this research is to analyze the financial feasibility of shallot farming development based on NPV (Net Present Value), Net B/C (benefit/cost), IRR (Internal Rate Return), and payback period criteria. The financial feasibility analysis through the calculation of cost and benefit components obtained from shallot business and investment criteria to determine the level of feasibility in quantitative terms. The result showed that NPV is IDR. 16,747,507.38, Net B/C 1.45, IRR for 4 period is 66.03% and payback period is 3.58.]]>

<![CDATA[Bricks are regarded as important material in building constructions. Basically, brick is processed by mixing clay and water then burnt under high temperature for a certain duration. Previous study in Indonesia shows that mixing local clay with additional materials could improve its characteristic, especially in terms of water absorption potentiality. Lampung has home industries which run brick making business traditionally. Moreover, this year Indonesian government has been organizing regional elections which attract campaigners to produce more vinyl banners as advertising media. As the event has already passed, vinyl banners eventually become environmental issue since they are not yet well managed. The aim of this study is to investigate the possibility and effect of red bricks mixtures along with vinyl banner waste. Fired-clay bricks dimensions including length, width, and height are 19 cm, 9.5 cm, and 5 cm respectively. Measurement has done by employing water absorption tests. Waste-added bricks absorb more water than the conventional one, about 11% higher. However, rice-husk-ash-added bricks perform similar to the normal bricks, it has slow rate of water absorption. Absorption rate of waste-added bricks also fast and exceed the conventional and RHA-added bricks. Modified red bricks surfaces are uneven, they show cracks and rough edges.]]>

<![CDATA[Kota Baru, a new capital Lampung province location, planned and developed since 2012, will be a densely populated in near time. The province located in near Semangko fault, southern of Sumatra Island, is a vulnerable area to earthquake. Seismometer was deployed for 15 points in Kota Baru for recording mictrotremor. The signal was analyzed by HVSR method produced fundamental frequency f0, amplitude A0, and seismic vulnerability index Kg. The range of frequency value is about 0.56 Hz to 1.46 Hz. The range of amplitude value is about 2.3 to 6.17. There is linear relation between Kg and the damage caused by earthquake. The Kota Baru classification of seismic hazard map was generated by plotting the value of Kg. The area at the northeast of Kota Baru is more risky to be inhabited because it has higher value of Kg. The more safety area located in near T7 and T15 because it has lower value of Kg than theothers.]]>
