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

Abstract

Indonesia is a region that is at risk of earthquakes. The impact of an earthquake is bad for the building structure, not only causing damage to the building, but also can cause the building to collapse. Therefore, to reduce the adverse effects obtained from earthquakes, it is necessary to design and evaluate the strength of building structures with resistance to earthquake loads. The method used in this study is dynamic response spectrum analysis to obtain the magnitude of the earthquake load. Evaluation of the strength of the building structure is carried out using structural analysis software to make it easier to do the analysis. This study aims to determine the ratio of the required strength in conditions without earthquake loads and conditions due to earthquake loads to the designed strength of the structure. Based on the results of this study, it can be concluded that the required strength obtained in conditions without an earthquake load reaches 8.33% to 90.62% of the designed strength, whereas in conditions due to strong earthquake loads the required strength obtained reaches 12.57% to 153.31% of the designed strength.Keywords: earthquakes, structural strength, dynamic analysis, response spectrum.

Abstract

Pembangunan infrastruktur di wilayah pesisir memerlukan penggunaan bahan konstruksi yang dapat bertahan dalam kondisi terpapar air laut. Namun, air laut memiliki pengaruh yang cukup besar pada kekuatan beton. Penelitian ini bertujuan untuk mengevaluasi dampak air laut dan lingkungan pesisir terhadap kekuatan beton serta tingkat karbonasinya. Sampel beton berbentuk kubus dengan dimensi 15x15x15 cm disubjekkan pada perawatan dengan air tawar dan air laut selama periode 7, 14, 28, dan 56 hari. Hasil penelitian menunjukkan bahwa beton yang diperlakukan dengan air laut memiliki kekuatan tekan yang lebih rendah dibandingkan dengan beton yang diperlakukan dengan air tawar, dengan nilai kekuatan tekan berturut-turut adalah 273,53 kg/cm2 , 302,23 kg/cm2 , 331,21 kg/cm2 , dan 316,01 kg/cm2 . Selain itu, beton yang terpapar lingkungan pesisir juga mengalami penurunan nilai kekuatan tekan pada usia 28 dan 56 hari untuk setiap sampel. Nilai kekuatan tekan pada sampel BAZ adalah 426,63 kg/cm2 ; pada sampel BTZ adalah 384,09 kg/cm2 pada usia 28 hari dan 361,05 kg/cm2 pada usia 56 hari; sementara pada sampel BSZ adalah 351,6 kg/cm2 pada usia 28 hari dan 342,2 kg/cm2 pada usia 56 hari. Hasil uji karbonasi pada usia 28 dan 56 hari menunjukkan bahwa sampel BUR dan BAZ tidak mengalami karbonasi dengan kedalaman 0 mm, sementara sampel BTZ mengalami karbonasi dengan kedalaman 4,4 mm pada usia 28 hari dan 6,4 mm pada usia 56 hari. Sampel BSZ memiliki tingkat karbonasi yang lebih dalam, yaitu 7,4 mm pada usia 28 hari dan 11 mm pada usia 56 hari. Hasil ini mengindikasikan bahwa semakin dalam tingkat karbonasi, semakin menurun kekuatan beton.
