Abstract

Bali has many rivers with river water discharge conditions is quite large and a lot of wasted at the mouth of the river in vain , because not all of the water used for agricultural needs and raw water . Current physical land in the mouth of the river has begun to change from agricultural land into building that support tourism in Bali This is in line with the development of tourism industry of small -scale tourism and large -scale tourism . In line with this condition, the problem is how the characteristics of the river mouth in Bali with the change in land use in the mouth of the river and how water resources management methods that go into the mouth of the river so that water resources be sustainably. Researchmethods that will be used is phenomenology . This is in accordance with the principle of preservation of objects that many studies related to water resources management system . The research process consists of two stages . Results obtained in the form of characteristics of the river , the river mouth morphology after land use change around the mouth of the river, based on secondary data ( reports of Bali Provincial Department of Public Works ) andresearch in the field ( primary data ) , this study uses the software as a tool of analysis . Karakteristik morphology Sowan estuaries ( Perancak and vicinity ) is influenced by the tide . The slope of the river estuary is very gentle with the deposition of sediments in the estuary level is relatively high .Research materials are mostly primary data are searched directly in the research area and equipped with relevant secondary data from the last 5 years of data. Sowan river basin area 205,818 km2 , with rainfall in the basin is about 1,900 mm per year . Kondition for environmental water quality in the river mouth area Sowan obtained Perancak beach water quality data obtained magnitude BOD levels 10.61 mg / land COD levels of 16.47 mg / l . Watershed wide Badung of 52,497 km2, land conditions in  the estuary area of Badung in Denpasar . Land use changes that often occur lately triggered sedimentation / siltation in the river cross-sectional area and also increase the discharge capacity of the body into the river so that it will increase the risk of flooding. Tukad Badung Denpasar flow splitting , 19,601 km river length,  with headwaters located 12 km to the north of Denpasar and empties into the Gulf of Benoa , an important source of raw water for the city of Denpasar and southern Badung regency.

Abstract

Dinding Penahan Tanah (DPT) yang berlokasi di Dusun Bantas, Desa Songan B, Kecamatan Kintamani, Kabupaten Bangli secara geografis terletak pada koordinat: 08o 13’ 03,5” Lintang Selatan dan 115o 24’ 57,9” Bujur Timur, mengalami keruntuhan pada 10 Februari 2017. Keruntuhan terjadi sehari setelah hujan ekstrim yang terjadi selama 4 hari mengguyur daerah sekitar Kecamatan Kintamani pada bulan Februari. Tingginya kerusakan yang terjadi perlu dilakukan analisa teknis untuk mengetahui penyebab terjadinya keruntuhan melalui observasi dan pengamatan di lapangan dan data-data terkait laporan dari dinas terkait. Tujuan dari analisa ini adalah agar DPT yang akan dibangun kembali menjadi lebih kokoh untuk menahan beban dan menghindari terulangnya kejadian serupa pada bangunan yang baru.Dari observasi dan fakta lapangan dan analisa numeris pada lereng longsor, keruntuhan DPT disebabkan oleh karena dimensi DPT yang terlalu ramping sehingga tidak mampu menahan tekanan tanah aktif saat jenuh air. Drainase DPT tidak berfungsi dengan baik sehingga tanah gampang jenuh saat hujan. Keruntuhan juga disebabkan oleh tergerusnya pondasi DPT akibat masuknya air pada retakan horisontal pada bahu jalan. Pondasi DPT tidak berada pada lapisan tanah yang stabil.Penanggulangan risiko bencana diawali dengan penilaian dan pemetaan risiko bencana. Pembelajaran terhadap masyarakat didaerah rawan bencana longsor dilakukan secara intensif agar mampu menilai secara visual ancaman terjadi. Upaya mitigasi lebih efektif lainnya dengan investasi pengurangan risiko bencana berupa penerapan system peringatan dini dengan teknologi tepat guna.

Abstract

The development of earthquake-resistant building designs led to developing an analysis method for earthquake loads, one of the performance-based methods. This method uses structural displacement as an approach. The purpose of this analysis method was to guarantee the structure's performance so that it will be able to withstand forces due to earthquake loads. In this paper, an analysis of a building structure's design was more reliable with applicable regulations in Indonesia and determined building performance based on FEMA 356. The study was carried out using the direct displacement method and the pushover analysis method, with the displacement targets and structure performance levels being compared with each other. Based on these results, it can conclude that the use of the direct displacement method and pushover analysis can produce almost the same displacement target values and structure performance levels. Comparison using pushover analysis design performance targets can be fulfilled so that the Direct Displacement Based Design Method can be used in structures. The total displacement value of the x-x (δT) direction is 0.300 m, and the y-y course is 0.115 m.

Abstract

The absence of an assessment of the level of damage and the condition of the Bali Mandara Hospital building makes the maintenance management plan contained in the umbrella contract only based on the damage that occurred in the previous year. Therefore, it is very difficult to determine which building infrastructure components require maintenance and repair first. This study examines the priority scale of infrastructure maintenance at Bali Mandara Hospital using the Analytical Hierarchy Process (AHP). In this study, researchers used a quantitative-descriptive approach. The assessment of the building condition index value is then determined by the priority scale of each component using the Analytical Hierarchy Process (AHP) method with the help of the Expert Choice Version 11 application and the SWOT Method. The results showed that the index value for the infrastructure condition of the Bali Mandara Hospital building was 89.492 with very good condition criteria and was in zone I, while the highest priority scale was faucets, namely 1,000, and the lowest priority was action on a scale of 0.050, where this priority scale can be used in planning. Standard Operating Procedure (SOP) and efficient maintenance management. So based on the results of this study, with SWOT analysis, maintenance management can develop a more effective and efficient maintenance plan and Standard Operating Procedure (SOP) by the building condition index and existing priority scale.

Abstract

The trigger factor for landslides is due to high rainfall intensity and long duration and the drainage system on the slopes is not good, causing the soil to become saturated. The Singaraja–Mengwitani City road section every rainy season always occurs landslides due to the geometry of the road adjacent to the slope because it is in a hilly area, as well as a drainage system that does not function during the rainy season. Based on the results of the previous soil investigation, the road section is a type of silty clay due to weathering of the ancient Buyan-Beratan volcanic rocks. The research was conducted through a field investigation with 2 drill points in a depth of 30 m, and slope stability analysis with the help of Geoslope software obtained. The value of the existing slope safety factor was 0.939, while at the time of moderate rain for 6 hours it was obtained SF<0.332, this condition indicates that the slope will fail so that it needs to be strengthened. The reinforcement is carried out with steel sheet piles is 4.49 m with a total length of sheet piles used is 6.49 ~ 7 m, based on the results of the analysis after being given reinforcement of steel sheet piles the safety factor value is 1.674, while when it rains it is moderate for 6 hours at 1,210, the slope is declared stable/safe because SF>1.0.

Abstract

To achieve the level of infrastructure performance as a middle-income country by 2025, as well as to catch up with the backwardness of infrastructure, specifically for toll road projects, the government targets that by 2021 Indonesia will have 5200 km of toll roads. Hence, there is a significant increase of 3000 km. The government, especially in the development of toll road infrastructure, gives a more significant portion to the purely private sector, BUMN, and Public Private Partnership - Government Business Entity Cooperation. Risk analysis is carried out by structuring risk using the RBS (Risk Breakdown Structure) method and multiplying the impact value and frequency to get the risk level value for each risk factor. The results of the analysis obtained from RBS are further analyzed based on the practical experience of project implementers to determine their actions in overcoming risks, then analyzed and discussed again using a table comparing the amount of risk, comparison of the level of importance of risk (importance level) and the level of risk based on the payment system. The results obtained from this study are the types of risk and the level of risk at each stage of the project.
