Abstract

One of the main factors causing flooding in an urban area is rainfall intensity. Perhaps this research has been widely discussed in other studies, but this research was conducted in an area with rainfall characteristics that are different from other areas, so this research is expected to provide further information for flood management and water structure design in related areas. The purpose of the research is to obtain and compare rain intensity methods in order to select a method that is suitable for rainfall characteristics in the sukarame area.  The short-term intensity calculation method uses the Mononobe method because this method only requires maximum daily rainfall data. The calculation of rain intensity approach uses Talbot and Sherman methods to find the appropriate rain intensity method. The results showed that high-intensity rain lasts for a short duration. From the comparison results, different rain intensity analysis results were obtained, this may be due to the use of different settings from each method. It is concluded that the Mononobe method with the Sherman equation is most suitable for rainfall characteristics. Key words : Rainfall Intensity, Mononobe, Talbot, Sherman, IDF Curve.

Abstract

This study analyzes the revetment structure located at Muli Beach, South Lampung, through wave analysis occurring at the beach. The stability of the coastal protection structure, revetment, at Muli Beach is of utmost importance due to safety and security concerns for beach users. If the revetment is unstable, it can cause damage to the structure and potentially pose hazards to the users. The aim of this research is to assess the stability of the revetment structure against high waves occurring at the beach. The analysis method employed in this study utilizes wave forecasting with a return period of 10 years. The analysis also encompasses the examination of the components constituting the revetment structure at Muli Beach. The research findings indicate that the composition of the revetment structure is unstable against high waves. The wave forecasting analysis at Muli Beach resulted in a significant wave height, Hs = 1,02 m and a wave height at breaking point Hb = 1,82 m. Regarding the structure's components, there are several shattered stones > 2, indicating inconsistency with the existing literature. In the analysis of the revetment toe protection, a stability coefficient value of Ns^3 = 290 was obtained, which can be considered safe. Based on these analysis results, it is recommended to implement necessary measures to prevent the collapse of the revetment structure during high wave events. Keywords: revetment, waves, stability, beach.

Abstract

Land use is used to determine the effect of community activities on the land use of an area. Currently, the search for land use information can be reviewed periodically with remote sensing technology. The aim of the research is to map land use and provide information to the public regarding the condition of land use in the Way Pubian Sub-watershed area. The method used in processing land mapping data is supervised classification based on the training samples that have been collected. The supervised classification method is available in ArcGIS software. The method of analysis refers to descriptive analysis, by describing the land use maps obtained. The results of the map show that land use in the Way Pubian Sub-watershed consists of ponds of 1.57 Ha with a percentage of land of 0.01%, forest land of 6719.14 Ha of a percentage of 57.83%, open land area of 122.58 Ha of percentage 1.06%, settlements 823.2 Ha a percentage of 7.08%, Plantations 2783.11 Ha a percentage of 23.95% and paddy fields 1169.34 Ha with a land percentage of 10.06%. Compared to Landsat imagery, map making is more effective if using high-resolution imagery, then Google Earth imagery is used as data processing material. The conclusion obtained by processing data with ArcGIS software helps in mapping land use, obtaining the area and percentage of land use. The percentage results show that the largest land use is forest land and the smallest land area is pond land.Keywords: map, land use, watershed, GIS, imagery

Abstract

Mangrove ecotourism is difficult to establish. This is caused by the lack of awareness of the community and village officials in managing these tourist attractions. Activities to develop the Petengoran mangrove ecotourism area to improve the welfare of coastal communities through the preparation of guidelines for the development of mangrove ecotourism for stakeholders from Gebang Village. So this study aims to determine the type, density value, frequency, dominance and important index value (INP) of the Petetengoran mangrove by collecting data using the line transect method by counting the number of species (trees, poles, saplings, seedlings). From the research results with 3 observation plots, four species were found, namely: Avicennia Marina, Ceriops Sp, Rhizophora Apiculata, Rhizophora Stylosa. The type of mangrove that has the highest important value index (INP) for the tree level is that of Rhizophora Apiculata (INP: 165.85) and the lowest is Ceriops Sp (INP: 7.14), for the sapling/sapling level the mangrove species has an important value index the highest and lowest was Rhizopora stylosa (INP : 15, 69). As for the seedling level, the species that had the highest and lowest importance value index were Rhizophora Apiculata and Rhizopora stylosa (INP : 165.85) and the lowest (INP: 15.69). It was concluded from the results that have been carried out that the Petengoran mangrove forest area can be said to be suitable for development as an ecotourism destination with the results of the analysis of the density of the mangrove vegetation showing that the dominant plant species is Rhizophora Apiculata, so that the condition of the mangrove forest in Petengoran, Padang Cermin District, is included in the condition category. good with moderate criteria, not too dense.

Abstract

AbstractIn class B aggregate foundation layer mixtures, the utilization of red soil can be used as an alternative material for a class B aggregate foundation layer binder. Aggregate binder is used to increase the bearing capacity of Class B aggregate foundation course. Red soil has shortcomings in its plasticity index value, therefore red soil needs to be stabilized with lime with the addition of a ceritain percentage to meet the standard plasticity index value of class B aggregate foundation layer requirement. The purpose of this study was to determine the utilization of lime-stabilized red soil as a binder for class B aggregate foundation layers by comparing CBR values. The method used was to compare the CBR values of class B aggregate foundation layer 100% red soil with a mixture of lime-stabilized red soil with the addition of 15% lime.The results of the CBR research of class B aggregate foundation layers show the addition of 15% lime stabilized red soil with a CBR value of 82,9%. For class B aggregate foundation layer 100% red soil, the CBR value was 69,7%.Keywords: Class B aggregate foundation layer, stabilized red soil, CBR

Abstract

The Bandar Lampung area which is quite routinely hit by floods is in Tanjung Karang Pusat District, the Jl. Wolter Monginsidi to Jl. Kartini. The reason is the high rainfall, as well as the curved road conditions and the performance of the drainage channel that is not optimal enough to accommodate the water discharge before carrying it to the Way Awi river which is on the road. The option that can be taken to reduce the risk of flooding is by evaluating the drainage channels on the road, taking into account the capacity of the drainage channels so that they are able to accommodate the flood discharge through them. The design discharge is calculated using hydrological analysis, rational methods, and based on maximum rainfall data for the last 10 years. For channel discharge capacity is calculated using hydraulics analysis and Manning's formula. The results of the analysis of the existing discharge capacity in most of the drainage channel segments are still able to accommodate the planned discharge with a 5-year return period of rain, so there is no need to increase the dimensions, except for segment 4, because the existing drainage capacity (Qs) is 0.700 m3/s smaller than design discharge (Qr) 1,238 m3/s. These conditions require the need to increase the dimensions of the drainage channel in order to accommodate the discharge through it.  Key words : drainage, hydrological analysis, hydraulic analysis, flooding.

Abstract

AbstractThe high occurrence rate of damage to buildings and infrastructure due to earthquakes necessitates a review or analysis of earthquake-resistant structural planning. Considering the importance of hospital functions, it is necessary to conduct an evaluation of the performance of the building structure under seismic loads using the latest standards to determine the structural suitability of the building. The level of safety in high-rise buildings is considered crucial to be known, so in this study, a case study was conducted on Building 5 of RSPTN UNILA using the method of response spectrum dynamic analysis. The structural analysis was calculated using a commercial structural analysis program in a three-dimensional model to determine whether the structure is safe or not according to the inter-storey drift limits specified in SNI 1726:2019. The results of the analysis show that as the earthquake acceleration increases, the drift value in the building structure also increases. The drift values obtained for the evaluated building are 15.5850% in the X direction and 19.3563% in the Y direction compared to the allowable drift. The drift (Δ) occurring in the building structure satisfies the allowable story drift (Δa) requirements according to SNI 1726:2019.Key words : structural performance, earthquake, dynamic analysis, spectrum response.  AbstrakTingginya tingkat terjadinya kerusakan pada bangunan dan infrastruktur akibat terjadinya gempa membuat perlu adanya peninjauan atau analisis terhadap perencanaan struktur tahan gempa. Mengingat pentingnya fungsi rumah sakit maka perlu diadakannya evaluasi kinerja struktur gedung terhadap beban gempa dengan standar terbaru untuk menentukan kelayakan struktur gedung. Tingkat keamanan gedung bertingkat tinggi dinilai sangat penting untuk diketahui sehingga dalam penelitian kali ini dilakukan studi kasus pada Gedung 5 RSPTN UNILA dengan menggunakan metode penelitian analisis dinamik respon spektrum. Analisis struktur dihitung menggunakan program analisis struktur komersial dalam model tiga dimensi bertujuan mengetahui apakah struktur aman atau tidak sesuai batas simpang antar tingkat dalam SNI 1726:2019. Hasil dari analisis yang dilakukan diketahui bahwa semakin besar percepatan gempa, maka nilai drift atau simpangan akan semakin besar juga pada struktur gedung. Nilai drift atau simpangan ini dipengaruhi juga oleh ketidakberaturan vertikal, sistem struktur, geometri gedung, dan fungsi gedung. Simpangan yang terjadi pada struktur gedung memenuhi syarat simpangan antar tingkat izin sesuai dengan SNI 1726:2019.Kata kunci : kinerja struktur, gempa, analisis dinamik, respon spetrum
