Abstract

Drainage functions to drain water so that there is no puddle on the road surface which can disrupt community activities and damage to road construction. On Jalan Harapan, the Rumbai Pesisir sub-district already has a drainage channel on the right with a height of 1.3 m and a width of 1.3 m and a left channel with a height of 1.3 m and a width of 1.1 m. However, there are still frequent puddles of water on the road surface. The condition of the drainage channel on the hope road is hollow, causing waterlogging in the area. The purpose of this research is to do a re-planning to improve the condition of the existing drainage channel so that it can drain water. The method used is the Gumbel distribution method to calculate the frequency of rainfall, SNI 03-3424-1994 to calculate the intensity of rainfall and the manning method to calculate the flow velocity. From the planning results, the dimensions are 1.75 m high and 1.5 m wide with an upstream elevation of 99,013 and a downstream elevation of 98.8108 for the right channel and the left channel with a height of 1.45 m and a width of 1.2 m with an upstream elevation of 98.429 and an elevation of 98.429. downstream 98,227 for the left channel. In conclusion, the dimensions of the right channel are 1.75 m high and 1.5 m wide, the left channel is 1.45 m high and 1.2 m wide.

Abstract

Konstruksi bangunan membutuhkan kondisi tanah yang memiliki daya dukung yang baik sehingga mampu memikul beban di atasnya. Tanah lempung dengan plastisitas tinggi yaitu tanah yang banyak mengandung butiran lempung. Sifat dari tanah lempung yang perlu diperhatikan yaitu sifat pemampatan, permeabilitas, dan kuat geser. Untuk menaikkan daya dukung tanah lempung tersebut dengan melakukan pemadatan, sehingga didapat kepadatan yang maksimum. Tanah asli dicampurkan dengan abu tandan sawit dan semen akan menaikkan nilai berat isi kering maksimum tanah lempung. Tujuan penelitian ini adalah untuk mengetahui pemadatan tanah yang dicampur dengan varaiasi persentase abu tandan sawit dan semen masing-masing 5%, 7,5%, dan 10 %. Penambahan abu tandan sawit dan semen dapat menunrunkan nilai kadar air tanah dan meningkatkan nilai berat isi kering tanah sehingga tanah menjadi lebih padat. Nilai berat isi kering terbesar di campuran 10 % abu tandan sawit dan semen yaitu 1,42 gr/cm³, dimana berat isi kering tanah asli nilainya 1,32 gr/cm³. Kesimpulannya terjadi peningkatan nilai dari berat isi kering tanah dan menurunnya nilai kadar air tanah dengan penambahan abu tandan sawit dan semen.

Abstract

The nature of the subgrade plays an important role in road construction. The subgrade can be compacted embankment. The physical and mechanical properties of embankment soil are values ​​or parameters to see the quality requirements. The purpose of this study was to determine the characteristics of the embankment soil as a subgrade. The method used is laboratory testing to obtain the physical and mechanical properties of the embankment soil. Soil samples were taken from Tenayan Raya, Kulim, Pekanbaru City. The results showed that the physical properties of the soil were classified as ML, PI 6.62%, and the mechanical properties of the soil with a CBR value of 17.8%. Conclusion The physical properties of the embankment soil should not contain organic matter and high plasticity. Mechanical properties of embankment soil for CBR value > 10% based on Bina Marga 2018 Revision 2 specifications for selected embankments.

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.
