Abstract

Flooding is a disaster that often occurs in the rainy season. The damage caused by this failure is not only material damage such as damage to houses, public facilities, and destruction of agricultural land, but also create disease outbreaks around the disaster site. One solution to reduce rainwater runoff needs to be made easy and practical recharge well model by utilizing local materials. The purpose of this research is the modeling of absorbing wells and drainage for prevention and control of flood hazard to achieve a healthy, safe, and comfortable. The research location is Lauwonu Village, Tilango District, Gorontalo Regency. Construction materials for modeling are local materials located around the site. The recharge wells are sized (2x1x1) m3 and (2x1,5x1) m3. If every household has a recharge well with a minimum volume of 2 m3, it will reduce rainfall runoff so that that flood disaster can be avoided.

Abstract

Parts of Gorontalo are hills and mountains close to community settlements, which are prone to landslides. To do a research on literature review that analyzes slope reinforcement models, which will be taken into consideration for slope improvement steps in Gorontalo. Slope reinforcement includes retaining walls, gravity walls, cantilever walls and crib walls. This research discusses slope reinforcement models and their stability behavior analysis. Secondary data is in the form of research journals on slope reinforcement models. Calculation data that will be used as experimental data for modeling other retrofitting walls are obtained from the results of research from one of the reviewed journals, namely multilevel gravity walls. The wall that will be analyzed is the retaining wall of a multilevel cantilever type of wall. Analysis of active soil pressure using the Rankine method and slope stability analysis using the slice method which is carried out with the help of 2D Slide software. Based on the results of the stability analysis of slope reinforcement with the selection of stratified cantilever wall reinforcement, the value of the safety factor against sliding (Fgs) is 1.63>1.5, the safety factor against overturning (Fgl) is 2.44>2.0, the safety factor against the collapse of carrying capacity (F) is 8.49>3.0, and the global safety factor value is 1.56>1.5. The value of the safety factor for shifting and rolling has decreased by 1% and 20% respectively compared to the gravitational wall. In the wall bearing capacity, there was an increase of 31%. Changes that occur in the safety factor in cantilevered walls are caused by changing factors in the dimensions of the walls which affect the strength of the structure in the soil holding force and the type of working principle of the walls. As for the global slope stability analyzed, there was a decrease in the safety factor by 5% after changing the type of reinforcement, but it showed that the slope was still stable, because the cantilevered wall type has a slender front wall dimension compared to the gravity wall which is more resistant to the risk of lateral slope movement.

Abstract

Konsumsi bahan plastik semakin hari semakin banyak sehingga akibat yang ditimbulkan semakin buruk. Karena barang berbahan plastik merupakan bahan polimer sintetis sehingga sulit terdegradasi di alam. Hasil observasi yang dilakukan mahasiswa kemudian dilanjutkan dengan rapat perencanaan program kerja yang akan ditawarkan untuk warga masyarakat dan karang taruna. Rapat tersebut menghasilkan keputusan bahwa program yang akan dilaksanakan salah satunya adalah pemanfaatn botol plastik bekas dan sampah plastik sebagai bahan konstruksi pembatas dusun dan tempat sampah. Pembuatan ecobrick memakan waktu yang cukup lama, oleh karena itu dapat dilakukan disela-sela waktu luang sehingga suatu saat bila sudah terkumpul dalam jumlah banyak bisa digunakan sekaligus. Apabila waktu yang tersedia cukup singkat isian botol dapat digantikan dengan pasir kering ataupun kerikil. Penggunaan botol dan sampah plastik sebagai batu bata ramah lingkungan tanpa disadari merupakan suatu langkah kecil yang lama kelamaan menimbulkan efek yang sangat besar bagi kelestarian lingkungan.

Abstract

Penelitian ini dilatarbelakangi oleh pembangunan Pasar Sentral Kota Gorontalo yang dibangun pada tahun 2000 dan telah dilakukan renovasi pada tahun 2020. Untuk merespon hal tersebut dilakukan penelitian analisis kapasitas dukung fondasi berdasarkan in situ test. Untuk keperluan tersebut perlu dilakukan pengujian kapasitas dukung tanah pada daerah lokasi pembangunan Pasar Sentral Kota Gorontalo tersebut. Kapasitas dukung tanah dan penurunan pada fondasi sangat berkaitan erat dengan beban struktur yang di atasnya. Pada lokasi penelitian ini dilakukan pengujian kapasitas dukung pada tanah berupa pengujian sondir dan pengujian N-SPT. Berdasarkan dari hasil uji N-SPT dilakukan analisis kapasitas dukung pada fondasi serta penurunan yang terjadi dan kemudian dianalisis dengan metode elemen hingga (Plaxis 2D). Hasil penelitian menunjukkan kapasitas dukung tanah pada titik BH.1 termasuk dalam kategori tanah dengan kapasitas dukung tanah lunak, sedangkan untuk kapasitas dukung tanah pada titik BH.2 termasuk dalam kategori kapasitas dukung tanah padat. Setiap lokasi memiliki nilai kapasitas dukung dan penurunan yang berbeda dikarenakan dari kedua lokasi BH memiliki tanah yang berbeda. Titik BH.2 memiliki nilai penurunan paling kecil yaitu sebesar 2,66 mm karena nilai kapasitas dukung tanahnya sangat besar. Semakin kecil kapasitas dukung pada tanah maka akan semakin besar penurunan yang akan terjadi pada bangunan. Semakin besar tekanan yang dipikul fondasi maka peluang untuk bangunan mengalami penurunan sangatlah besar.

Abstract

The issuance of SNI 1726:2019 regarding the response of the earthquake spectrum in Indonesia has not accommodated districts and sub-districts. The distribution of values on the zoning map for Indonesia is only divided by province, including Gorontalo. Gorontalo province is included in the high-risk zone because its soil motion parameter Ss is maroon with a value of 1.2–1.5g, while the ground motion S1 parameter is light brown with a constant acceleration spectrum of 60% g, Thus, it is necessary to divide the micro-scale map of the earthquake response spectrum zonation. This research aimed to analyze the value of the earthquake spectrum created with a zoning micro map in Gorontalo Utara District. This research is expected to be an initial reference in planning for the earthquake-resilient building, particularly in Gorontalo Utara District. The object of research is located in Gorontalo Utara District. This research only used secondary data obtained from several agencies, namely, BPJN Gorontalo and drilling service companies in Gorontalo Province. The secondary data used is the result of SPT (Standard Penetration Test) driling. Preparation of spectrum responses and zonation micro map referred to the guidelines of SNI 1726:2019 and the QGIS learning module. The data analyzed are based on the N-SPT data, which previously had been processed. The data obtained were processed to obtain the value that became the goal of this research by correcting the N-SPT (Standard Penetration Test) data, making the earthquake response spectrum plan, and making the response spectrum using QGIS 3.16. Gorontalo Utara District is classified as a soft-to-moderate site with an value of 9-37. The short period bedrock acceleration value SS is 1.49-2.33g. When viewed by color, Gorontalo Utara District is including in maroon to purple. The value of 1 second bedrock acceleration period S1 is 0.6-0.78. When viewed by color, it is including whitish orange to pink. The peak ground acceleration value PGA is 1.49-2.33g which, by color, is included in yellowish orange to red. The value of bedrock acceleration for a period of 1 second and the highest peak ground acceleration value occurred in Ilangata Village with SS values ​​of 2.12-2.33g, S1 0.74-0.78g and PGA values ​​0.79-0.85g. Meanwhile, the lowest value occurred in Deme 2 Village with an SS value of 1.49g, S1 0.6g and a PGA value of 0.6g. It shows that the higher the acceleration value, the greater the earthquake that occurs, and vice versa. Based on the results of this study, the acceleration value affects the estimation of the earthquake that occurs, or the acceleration is directly proportional to the force.
