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.

Betung in the Pasawaran area. Geological setting of this area showed that the dominant lithology of Mt. Betung is pyroclastic, andesite, and breccia rocks. These volcanic deposits have the potential to move the materials down-slope by the force of gravity, steep slope, and high water-content. We have investigated some area with the potential of a landslide along OAIL construction area, which may be the cause of the landslip as well. We applied electrical resistivity tomography to analyse the electrical properties of the subsurface soil and determine the vulnerable area of the landslide. The result indicated that the area is divided into high resistivity at the top of the soil and low resistivity below. These high resistivity numbers are caused by pyroclastic flow while the lower one is caused by fracture-filled, mostly with water and clay.","PeriodicalId":383398,"journal":{"name":"Journal of Science and Application Technology","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122036467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

In another aspect of a tropical country, Indonesia has a reasonably high rainfall in the rainy season. The problem of this research is that the rainwater that has not been utilized and managed to maximize so that only becomes runoff. The community can utilize rainwater for the daily need. This paper presents methods and prototypes of rainwater harvesting and collection at the research locus. Methods of rainwater collection can be done with a rainwater harvesting system in the form of gutter mounted on the roof of the building as a tool to direct the flow of rainwater on the roof to the shelter. Rainfall compared to the roof area, will produce the volume of stored rainwater reservoir as a parameter. The novelty proposed in this study is the value and variable of water parameters in the case study of research implementation This case study was carried out in one of the buildings at Lampung State Polytechnic. The building has 96.72 m2 of roof area with daily average rainfall equal to 8.6 mm/day (January to May 2018 period). Hence rainwater potency which can be accommodated per day by society is equal to 0.582 m3/month with assumption only 70% water rain that collected because of water loss. In the rainy season, the volume of actual rainwater that can be collected as much as 0,831 m3/month by ignoring water loss due to evaporation. The quality of rainwater analyzed based on several parameters is pH 4.4, temperature 27,5 oC, turbidity 2.02 NTU, total dissolved solids 20.48 ppm, iron <0.110 ppm, calcium 3.36 mg/l, magnesium 0.233 mg/l, lead <0,021 ppm, hardness 3.69 mg/l, and total coliform 6,1 CFU/100 ml.
