Abstract

Tanah yaitu material yang terdiri dari butiran mineral, organic, dan endapan yang relative lepas. Klasifikasi tanah sistem unified (USCS) dilakukan untuk menentukan pengelompokkan jenis tanah tanah berdasarkan distribusi ukuran butirannya.Jenis tanah baik itu sifat fisis dan mekanis merupakan faktor penting yang harus dipertimbangan dalam perencanaan konstruksi agar tidak terjadi kegagalan konstruksi. Tujuan penelitian ini adalah untuk mengklasifikasikan jenis tanah yang terdapat di Kecamatan Mandau Kabupaten Bengkalis. Metode yang digunakan adalah metode klasifikasi USCS. Peneltian ini menggunakan dari 4 titik yang terdapat di Kecamatan Mandau Kabupaten Bengkalis. Analisa yang dilakukan adalah dengan mengambil sampel tanah di lapangan, kemudian dilakukan pengujian sifat fisis di laboratorium. %. Untuk klasifikasi yang diperoleh yaitu tergolong tanah lempung dan tanah lanau. Klasifikasi tanah dipengaruhi oleh nilai Indeks Plastisitas (PI), dari hasil penelitian ini nilai Indeks Plastisitas terbesar yaitu sampel tanah titik sebesar 26.54 dengan klasifikasi tanah MH lanau tak organik. Kesimpulannya klasifikasi tanah berdasrkan metode USCS pada sampel tanah yang diuji yaitu tergolong klasifikasi tanah lanau dan lempung. Klasifikasi ini diperoleh berdasarkan nilai lolos saringan No.200 dan nilai LL serta PI.

Abstract

Riverside areas have unique and varied characters that are not the same as others in terms of social, economic, cultural, and environmental aspects. The unique and specific character of the Pulau Semut Tourism object located in the Limbungan Village Pengambangan Area can be developed according to its potential. The location is on the side of the river which is still natural because it has a mangrove forest that is still beautiful. The local wisdom of this tourist attraction is that it is managed by the local community, with tourist destinations that are still natural, and there are several local products from fish processing that are worth developing as a local potential-based tourism concept. Partners still need to be assisted in terms of preparing local potential-based tourism concepts. The methods used are the discussion method, activity planning method, and implementation method. The result is that the concept displayed on the map is the local potential, namely the balimau spot and the culinary meatballs of rasau fish. In conclusion, the preparation of the Ant Island tourism concept emphasizes the local potential of Ant Island tourism.

Abstract

Land has a very important role in the world of construction such as buildings, bridges, and also road construction. Soil acts as the foundation of construction where the soil must be able to withstand the construction load that stands on it. On Jalan Badak, Tenayan Raya District, Pekanbaru City, Riau Province will be built housing and rigid roads. The problem is, in other locations that are not far from the construction site, there is also a subsidence (change in volume) in the construction of rigid roads due to the traffic load on it. This study aims to analyze the value of shear strength in clay soil stabilization using layers of plastic sacks and coconut coir ash waste. The research method is an experimental study in the laboratory based on SNI 3420:2016 using clay soil taken from Jalan Badak Ujung, Pekanbaru City, Riau. Soil stabilization material with a mixed variation percentage of 15% of the dry weight of the soil. There are 3 variations used, variation 1 is the top plastic sack layer and the ask 15% mixture, variation 2 is the bottom plastic sack layer and the ask 15% mixture, variation 3 is the top and bottom plastic sack layer and the ask 15% mixture. The test specimen is fermented for 7 days, then the sample is tested using a direct shear tool . The results showed a significant increase in the variation 3 test specimen, where the shear strength of the soil increased by 122.06% and the cohesion value increased by 54.35%.
