Abstract

Kemampuan mengembang dan menyusut tanah merupakan masalah bagi bangunan yang terletak di atas dansekitarnya. Deformasi yang diakibatkan tanah ini, seringkali tidak dapat disangga oleh kekakuan strukturbangunan. Dampaknya pada struktur adalah rusaknya struktur dinding, terangkatnya struktur plat, rusaknyastruktur jalan, jembatan, jaringan pipa, dan berbagai struktur bawah tanah lainnya. Beberapa ruas jalan diBoyolali mengalami kerusakan yang diduga akibat aktivitas tanah ekspansif. Penelitian ini bertujuanmengindentifikasi tanah ekspansif dan mengamati hubungan antara indeks plastisitas dan batas susut denganperilaku potensi mengembang tanah pada daerah tersebut.Perilaku potensi mengembang diamati dalam dua kategori yaitu : persentase mengembang dan tekananmengembang. Kedua perilaku tersebut diukur menggunakan Oedometer. Hasil pengujian menunjukkan bahwaindeks plastisitas mempunyai hubungan yang lebih kuat dibandingkan batas susut terhadap persentasemengembang dan tekanan mengembangnya. Semakin besar indeks plastisitas semakin besar persentasemengembang dan tekanan mengembang, sebaliknya semakin besar batas susut maka semakin kecil persentasemengembang dan tekanan mengembangnya.Kata kunci : batas susut, indeks plastisitas, Oedometer, persentase mengembang, tanah ekspansif, tekananmengembang.

Abstract

In the field of construction, particularly in geotechnical engineering, uncertainties in foundation design approaches are frequently encountered. Geotechnical uncertainties, especially in foundation design, pose complex challenges due to the heterogeneous nature of soil and data limitations. Dynamic load testing on pile foundations is an alternative method to static load testing in geotechnical engineering for evaluating pile capacity and behavior. The results of this analysis will be compared to the design capacity of pile foundations in the breasting dolphin structure. This study on a breasting dolphin structure utilizing Steel Pipe Pile (SPP) foundations with a diameter 610 mm. PDA tests were conducted on piles at points G6-23, G7-33, G7-38, and G8-46. The study begins with a literature review to comprehend methods and theories related to pile capacity analysis based on calendaring and PDA testing. Calendaring data were analyzed using empirical methods such as the Hiley Formula to estimate the dynamic bearing capacity of each pile. The pile capacity calculated using the Hiley Formula is generally higher than the results obtained from the Case Method and CAPWAP Analysis. The relationship between pile capacity based on the Hiley Formula (calendaring) and the Case Method (PDA test) yielded a linear regression equation of y = 1.0785x - 983.07 with R² = 0.2385, indicating a weak correlation. Meanwhile, the relationship between pile capacity from the Hiley Formula (calendaring) and CAPWAP Analysis (PDA test) resulted in a linear regression equation of y = -0.006x + 2909.8 with R² = 1×10?¹, indicating almost no linear correlation between the two.

Abstract. Road is one of the transportation infrastructure that plays an important role in supporting regional development, increasing the regional economy, facilitating the mobility of people, goods and services. For this reason, in order to support national economic activities, the Ministry of Public Works and Public Housing through the Directorate General of Highways carries out the planning and construction of several new roads on an ongoing basis. In addition, for existing roads, the Directorate General of Highways needs to carry out maintenance so that existing assets can continue to function. The threat of natural disasters and the instability of road bodies is a serious problem. This can cause damage to the road body and even the road body can be cut off suddenly, resulting in reduced road performance. One of the roads in Maybrat district, precisely in the Ayawasi – Sisu KM 273+500 section, experienced a road collapse that cut off access between districts, resulting in a stagnation of economic activity. Therefore, a landslide handling design is needed so that the road can be accessed again.The design process was carried out through several stages, including Preliminary Survey, Hydrological Survey, Geotechnical and Geological Survey, Topographic Survey, and Planning. In the planning process, the most effective and efficient design will be selected according to field conditions. Slope stability analysis using Slope/W software. Based on the results of the planning, the design of the Concrete Soil Retaining Wall with bored pile reinforcement is used as an alternative treatment because it can be done easily in the field and can overcome the problem of landslides in the area.Keywords: Safety factor; Concrete Retaining Wall; Bored Pile; Landslide; Slope-W

Abstract

Sungai Gandul merupakan anak Sungai Bengawan Solo yang mengalir di 3 kabupaten yaitu Kabupaten Boyolali, Kabupaten Klaten dan Kabupaten Sukoharjo. Banjir pernah terjadi pada aliran Sungai Gandul tepatnya di Desa Gombang, Boyolali. Intensitas hujan yang tinggi serta arus sungai yang deras menyebabkan gerusan pada dinding sungai hingga mencapai pondasi rumah warga. Jika dibiarkan gerusan tanah berpotensi semakin meluas di sepanjang pinggiran sungai. Maka perlu dilakukan perhitungan debit banjir rencana sebagai upaya pencegahan, penanggulangan banjir, maupun perencanaan infrastruktur air. Sebelum melakukan perhitungan, terlebih dahulu dilakukan survei dan wawancara untuk mengetahui kondisi aliran sungai Gandul. Kemudian dilakukan analisa untuk mengetahui luas DAS Gandul dengan software QGIS 3.10.6 dan debit banjir rencana dihitung dengan Metode HSS Snyder serta pemodelan debit banjir rencana dengan software HEC-HMS 4.12 kala ulang 25 tahun. Berdasarkan hasil survei dan wawancara dapat diketahui bahwa pada aliran Sungai Gandul banyak terdapat sampah organik dan anorganik serta terdapat sedimen. Luas DAS Gandul yang di analisis dengan software QGIS 3.10.6 adalah 140.02 km2 dan debit banjir rencana yang dihitung dengan metode HSS Snyder menggunakan software HEC-HMS kala ulang 25 tahun sebesar 138.8 m3/s.

Abstract

Revetment is a strengthening structure on river slopes from erosion. Erosion of river slopes can widen the wet cross section of the river and increasing scouring can endanger the surrounding buildings. The construction of the Demangan Water Gate in Surakarta City (Phase I) is planned at the mouth of the Pepe river downstream. The construction work will result in changes in river morphology, therefore it is necessary to protect the river slopes so that landslides do not occur. Apart from being a river slope protector, the Revetment design can also be a recreation area and an inspection road. The construction to be used is a concrete sheet pile revetment with reinforcement of the piles behind it as an anchor. Between the concrete sheet pile and the concrete pile, it is connected by a beam-slab structure so that it becomes a portal system. River slope stability analysis using GeoStudio2018 R2 software. River slope conditions that may occur are applied in several modeling, including: River slope conditions without Revetment reinforcement, River slope conditions with Revetment reinforcement, Conditions when changes in river water level elevation occur and river slope conditions when erosion occurs. Based on the results of modeling analysis on the original slope when the river water level increase then recedes has the smallest safe number (SF = 1,822). This is because on the back side of the Revetment, the active soil pressure is in a saturated condition, while the front side of the Revetment loses hydrostatic pressure as a counterweight. The highest safety number is in slope modeling with Revetment strengthening when the river water level increase (SF = 3.114), because the hydrostatic pressure on the back and front of the Revetment is balanced. Revetment construction on river slopes increases the safety rate by 30.64% - 43.70%. With the strengthening of the river slopes, it is hoped that it can provide sufficient security from the main function of protecting the river slopes and obtaining additional functions as a recreation area.

Abstract

Sebagian besar penduduk Indonesia bergantung pada pertanian sebagai sumber pangan, ketersediaan air irigasi dari suatu bendung dapat mempengaruhi tingkat keberhasilan sektor pertanian serta menentukan tingkat ekonomi nasional. Bendung Baran mengairi daerah irigasi (D.I) dengan luas area 179 ha. Penelitian ini bertujuan untuk mengetahui sistem operasi Bendung Baran terhadap ketersediaan air dan kebutuhan air irigasi. Metode yang digunakan yaitu metode FJ.Mock untuk menghitung ketersediaan air, metode KP-01 untuk menghitung kebutuhan air irigasi, dan metode imbangan air untuk menghitung simulasi operasi. Data hujan yang digunakan adalah Stasiun Waduk Cengklik selama 10 tahun (2013-2022), data klimatologi, data teknis Bendung Baran, dan skema/layout jaringan irigasi. Hasil perhitungan ketersediaan air mampu melayani kebutuhan air irigasi dengan debit bulanan rerata sebesar 2,73 m3/detik, dimana debit terbesar dibulan Januari sebesar 5,495 m3/detik dan debit terendah dibulan Agustus sebesar 0,93 m3/detik. Hasil perhitungan kebutuhan air irigasi menunjukkan debit rerata bulanan sebesar 0,44 m3/detik, dimana debit terbesar diperoleh sebesar 0,60 m3/detik pada periode kedua bulan Juni dan debit terendah diperoleh sebesar 0,21 m3/detik yaitu pada periode pertama bulan Maret. Hasil perhitungan simulasi operasi Bendung Baran menunjukkan ketersedian air dan kebutuhan air irigasi pada masa tanam padi tidak memenuhi pada bulan Juli dan Agustus. Hal ini dikarenakan minimnya curah hujan, terdapat beberapa jaringan irigasi yang rusak, dan adanya penimbunan sampah, sehingga hasil perhitungan perubahan volume tampungan ditambah dengan volume tampungan awal Bendung Baran berada dibawah tampungan minimum Bendung Baran.

Abstract

Slope instability is caused by several lithological and structural factors, slope geometry, relative relief, ground water, as well as changes in use and land cover. Mountainous areas, development and expansion of infrastructure networks can inadvertently cause natural slope shifts, thereby negatively impacting the stability of the excavated slope. Analysis of the geotechnical properties of soil and rock is important for understanding and predicting the possibility of landslides at certain locations. Geotechnical analysis is needed to carry out slope stability analysis which is carried out using GEO5 software. Construction of T/L 150 KV GI Kambang – GI Tapan, Tower TW. 203 with a tower structure at the top of the slope. Based on these conditions, a comprehensive study is needed to analyze the stability of natural slopes due to tower loads. Soil Type, Parameters c' and ?' (Drained), Parameters Cu and ? (Undrained) and soil properties index are based on CPT test results. The Bishop, Spencer, Janbu and Morgenstern-Price methods on natural slopes, tower loads, Natural with Tower+Pile Loads, Natural Slopes with Tower+Pile Loads, Earthquake Loads produce a safe condition against failure in Short-Term (Construction) and Long-Term conditions. Term (Operational). Analysis of the Fellenius method on natural slopes and tower loads in Short-Term (Construction) and Long-Term (Operational) conditions shows unsafe conditions. The safety factors resulting from the Bishop, Spencer, Janbu and Morgenstern-Price methods do not show significant differences in values.
