Perencanaan pondasi perlu diperhatikan dalam perencanaan bangunan agar tercapai suatu kestabilan dan keamanan. Dalam perencanaan pondasi dipengaruhi oleh banyak faktor, diantaranya kondisi tanah. Dengan kondisi tanah yang berbeda dalam hal ini kedalaman yang berbeda dan dengan adanya muka air tanah yang dangkal mempengaruhi perencanaan pondasi. Seperti halnya tanah di daerah Suwung yang berdaya dukung rendah dengan muka air tanah yang cukup dangkal, sehingga perlu diketahui tipe pondasi dangkal yang dapat memenuhi syarat untuk kondisi tanah di Suwung. Untuk mengetahui karakteristik tanah dilakukan dengan pengujian di laboratorium yaitu pegujian sifat fisik dan mekanik. Pengujian sifat fisik tanah yaitu pengujian kadar air (Wc), berat jenis (Gs), batas-batas Aterberg dan berat volume tanah (γ). Pegujian mekanik dengan tes triaksial UU. Berdasarkan tes triaksial UU yang dilakukan di laboratorium diperoleh daya dukung tanah (qu), nilai kohesi (c), dengan sudut geser (Ø) untuk tanah yang terletak di atas muka air tanah yaitu tanah pada kedalaman 1 meter dan tanah yang terletak di bawah muka air tanah yaitu tanah pada kedalaman 2 dan 4 meter. Dari nilai daya dukung tanah yang dihitung dengan rumus Terzaghi, diperoleh besarnya nilai daya dukung tanah terendah pada kedalaman 1 meter sebesar 54,09 kN/m2, nilai daya dukung terendah pada kedalaman 2 meter sebesar 57,37 kN/m2 dan pada kedalaman 4 meter diperoleh daya dukung terendah 66,51 kN/m2. Hasil perhitungan menunjukkan bahwa perencanaan pondasi telapak biasa dengan beban aksial kolom yang cukup besar P = 2253,122 kN tidak memenuhi syarat, karena akan menutupi lebih dari sebagian areal bangunan, sehingga dalam hal ini sebaiknya dipergunakan jenis pondasi dangkal yang lain yaitu pondasi pelat. Pondasi pelat yang direncanakan adalah pondasi pelat dengan balok. Pondasi pelat direncanakan pada kedalaman 1 meter karena daya dukung tanah telah memenuhi syarat. Setelah melakukan perhitungan maka diperoleh bahwa pondasi pelat dengan balok dengan tebal pelat 25 cm dan balok pondasi 45 cm × 90 cm, dapat memenuhi persyaratan sesuai daya dukung tanah yang diijinkan. Kata kunci: pondasi dangkal, lempung lunak, muka air tanah dangkal.

ABSTRACT Electricity supply is very important to improve people's lives. In Indonesia electricity is mostly generated by PLN as the state company that provide electricity for the entire people of Indonesia. PLN’s load is very high to provide electricity and to reduce the load of PLN, the potential of the electricity source should be utilized. One of the locations that have been built and used for micro-hydro power plant is the irrigation canal in the Tangeb village, Mengwi, Badung, Bali. Since it was built in 2014, micro-hydro power plant is expected to be used to provide electricity to the Pura Dalem within 100 meters from the power plant site, but can not function as expected because some parts of the structure were damaged, particularly on the foundation. In order for micro-hydro power plants can be used there should be analysis of the feasibility of existing structures. The research process begins with a review of the research sites, further soil sampling and ground testing in the field. The soil samples were tested in the laboratory. The test results of soil samples in the laboratory and field testing is used to calculate the carrying capacity of the land. The results of the soil bearing capacity were used to design the foundation. Analysis of the framework turbine is also conducted to determine whether the order turbines can still be used. Measurement of flow velocity is also performed to calculate the flow rate so that the electrical potential can be known. The results of the analysis of the feasibility of power plant micro-hydro in the Tangeb village obtained subgrade on the location of the turbine has a high bearing capacity that obtained the lowest allowable bearing capacity (qall) = 36.763 t/m2 based on test results in the laboratory, and the position of the hard soil in 1 meter depth. For steel frame buffer turbines, based on the results of the analysis with 9.7 ETABS program obtained that turbines are qualified or steel frame secure enough to support the movement of the turbine. The foundation of the turbine needs to be fixed with shallow foundation with a size of 0.95 m x 0.95 m, with a thickness 0.3 m and foundation depth of 1 meter. Reinforcement of foundation used for tension reinforcement φ 12 with a distance of 9 cm between the reinforcement and shrinkage reinforcement φ 12 with a distance of 18 cm. Potential electricity or power can be produced based on the calculation of the speed of the water, the water discharge resulting in low water level conditions is (W) = 3.3 kW.

ABSTRACT The rapid development of tourism in Bali demands the availability of tourism facilities such as hotels, villas, inns and restaurants that can improve services to tourists. Due to the difficulty of finding land to build hotels and villas as well as to get a natural atmosphere, many villas and hotels are built on steep slopes and even on the edge of a cliff. One of the many villas and hotels planned to be built on steep slopes is a villa in Dukuh, Tegalalang, Gianyar, Bali. Before the tourism facilities are built it is necessary to analyze the safety of the slope and the soil bearing capacity in the location of the villa so it can be planned the depth and the size of the foundation that meet the safety requirements. Slope safety analysis has been done using SLOPE/W 2007 program and with manual calculation using Bishop method. For this analysis is required some data ie SPT data, CPT data, soil shear angle (ϕ), soil cohesion value (c), soil density (γ) and load on the building. The results of the analysis show that the location has a slope of 25 ° - 33 ° so that it is quite steep. The slope safety value (SF) obtained with the SLOPE / W is 1.00 in the location A-A and 1,431 in the B-B location, whereas the Bishop method is 0.91 in the location A-A and 1.10 in the location B-B, and it is quite vulnerable to the landslide. Analysis of foundation bearing capacity is planned with single bored pile with length of pile is 10 meters and using pile diameter 20 cm, 25 cm, 30 cm, 35 cm, 40 cm and 50 cm, is obtained the lowest allowable pile capacity based on data CPT and the highest allowable pile capacity based on laboratory data. Based on the structural analysis is obtained the maximum axial load (Pmax) on the foundation is 68456.67 kg and the pile diameter is 30 cm. The minimum axial load (Pmin) is 18085.26 kg and the pile diameter is 20 cm. Keywords: steep slope, Tegalalang, slope safety, bored pile

ABSTRACT Indonesian government has built many dams in some areas and dams that have been built mostly earth dam. Earth dam becomes an option to be built because it was easier to obtain material to build the dam. Building process can be faster. Benel Dam in Melaya sub-district, Jembrana district, Bali province which had been evaluated was an earth dam that had been built in 2010. In order to provide benefits in the long time, the control of the seepage in the dam was needed so that safety can always be monitored. Measurements that were performed to determine the safety of the dam was measurement of the seepage discharge that occurs in the foundation. Therefore it is important to calculate the seepage discharge during the rainy season because in rainy season the water level in the upstream reaches the maximum position so it will cause maximum seepage in the foundation of the dam. The analysis was performed with SEEP/W and flow-net, with no cut off condition and with cut off. The result of the analysis that has been done, the seepage discharge in the dam’s foundation without cut-off for rainy season condition calculated with SEEP/W equal to 3.162 × 10-6 m3/sec and with cut-off obtained 2.077 × 10-6 m3/sec. While seepage discharge in the foundation of the dam without cut-off for rainy season conditions calculated with flow-net obtained 3.15 × 10-6 m3/sec and with a cut-off obtained 1.85 × 10-6m3/sec discharge. The results of this calculation show that the installation of cut off can reduce the amount of seepage. The seepage that occurs in the foundation of the dam was smaller than the allowed seepage that was 4.9206 m3/sec, so that the seepage discharge through the dam's foundation was safe for the dam. Key words: earth dam, flow-net, seepage discharge

Rapid exploitation of land in Bali, especially in the Kuta area due to the development of tourism, makes it difficult to obtain land and the price is expensive, so that the available land should be maximally used. The impact of maximum land use is the influence on the structure of the building to be built. The building structure component which affected is the foundation. Due to the very tight density of the building, it is necessary to consider the shallow foundation design that was widely used in the Kuta area to avoid structural failure, so that the designed buildings could stand safely. If the foundation receives an eccentric load, it will be very dangerous for the building if it does not fit between the load received and the size of the foundation being made. This would be disastrous in case of a construction failure due to a design error, so it was desirable to do research on the design of the shallow foundation with an eccentric load on the buildings located in the Kuta tourist area to obtain an adequate shallow foundation design based on the soil data and structural load will be built. To analyze the bearing capacity of the soil and the design of the foundation, it is necessary to provide data from land investigation in the field. Land investigation in the field was conducted with CPT. Based on CPT results obtained hard layer soil at a depth of 2 - 2.2 m. The shallow foundation was planned at a depth of 1.6 meters and the foot size of 1.5 m x 1.5 m with minimum allowable bearing capacity (qa) was 20,99 t/m2. The result of analysis of 2-storey building structure resulted axial load (P) was 25750.88 kg, moment about the X axis (Mx) was 2529.70 kg m and moment about the Y axis (My) was 2929.65 kg m. The dimensions of the footing are 1.5 m x 1.5 m and the thickness (t) was 580 mm. Minimum pressure on foundation (q min) was 6.238 t/m2 and the maximum pressure on foundation (q max) was 17.583 t/m2. For bending reinforcement was used 19 mm diameter reinforcing steel with a distance of 150 mm.

Rapid population growth leads to the expansion of residential areas, increasing the demand for land. Unpreparedness in anticipating the speed and dynamics of urban growth can result in the emergence of slum settlements. This study focuses on the settlements in Pengambengan Village, Jembrana Regency, Bali, which are predominantly inhabited by fishermen and are considered to be slums. If the growth of these slum settlements is not controlled, the environmental quality will continue to decline as these settlements expand. Therefore, it is crucial to understand the characteristics of these settlements. To understand the characteristics of these slum settlements, it is crucial to examine their features. Through this research, an analysis will be conducted to determine the characteristics of the slum settlement in Pengambengan. This study employed a mixed-method approach, combining data collection through observation and interviews, as well as data collection from various sources to complement existing survey results. The collected data was then analyzed and assessed based on the Regulation of the Minister of Public Works and Public Housing of the Republic of Indonesia Number 14/PRT/M/2018. The results of the analysis, which align with the 7 slum conditions including building structures, roads, water supply, drainage system, wastewater management, waste management, and fire protection, yielded a total score of 18. This indicates that the residential in Pengambengan is at a mild level of slum conditions. Despite being relatively low in slum severity, two important aspects should be noted-the provision of qualified drinking water and awareness of fire hazards, as these could have severe consequences for the residents of Pengambengan.
