Abstract

Salah satu infrastruktur yang berperan penting dalam berkembangnya suatu daerah adalah infrastruktur jalan. Kondisi kerusakan dini pada jalan raya terutama disebabkan oleh muatan berlebihan kendaraan berat (overloaded), ketidaksesuaian standar mutu lapisan perkerasan jalan untuk lalu lintas berat, kekeliruan dalam pedoman penentuan tebal lapisan perkerasan jalan, serta kurang baiknya sistem drainase jalan. Rekayasa Lapangan merupakan bagian penting dari kegiatan proyek untuk menuju penanganan jalan secara optimal dari sisi mutu, biaya dan waktu. Kebijakan diperkenalkannya simplified design dalam perencanaan jalan membuat sebagian besar perencanaan teknis jalan nasional dilakukan dengan menggunakan prinsip simplified design. Tujuan dari penelitian ini adalah untuk menghitung tebal peningkatan lapis tambahan (overlay), dan mengetahui kebutuhan biaya rehabilitasi dengan menggunakan pendekatan simplified pada ruas jalan tegineneng – sp. tanjung karang. Hasil dari penelitian ini yang menggunakan pendekatan simplified didapat perencanaan tebal lapis tambah (overlay) pada STA 13+449 - 15+849 sebesar 18 cm, STA 25+188 – 26+488 sebesar 18 cm dan STA 31+650 – 32+450 sebesar 16 cm untuk ruas jalan tegineneng – sp. tanjung karang. Dari hasil data yang didapatkan yaitu tebal lapis tambah (overlay) biaya rehabilitasi dengan pendekatan simplified untuk ruas jalan tegineneng – sp. tanjung karang sebesar Rp 52.253.768.426,00,-. Kata kunci :     pendekatan simplified, tebal lapis tambah (overlay), rencana anggaran biaya, rehabilitasi.

Abstract

The Way Umpu Bridge is located in Blambangan Umpu District, Way Kanan Regency which ispart of the Trans-Central Sumatra road section. In the structural elements of the bridge damageoccurs in the structural elements on the bridge so that it can endanger road and bridge users.Therefore effective and efficient planning is needed for the design of the new bridge.Standards used as a reference in planning the Way Umpu Bridge are SNI 1725-2016, RSNI T-02-2005 and PUPR PERMEN NUMBER 28 / PRT / M / 2016. By using supporting software for thecalculation and design of AutoCAD 2017, Microsoft Excel 2013, Google Earth Pro and SAP 2000V 14.The results of this plan are (1) effective type of bridge top structure is a class A bridge framestructure with a span length of 60 m, (2) the type of effective lower structure used is a supportedT-type support and the foundation of the pre-cast concrete piles ( rotating) pile), and (3) totalconstruction costs provided by labor costs, supply of materials and equipment, heavy equipmentoperating and rental costs and taxes of Rp 16,644,725,377.

Abstract

Traffic accidents are serious problem in Bandar Lampung City, especially the Soekarno-Hatta Bandar Lampung By Pass Road, considering that this road is the primary arterial road that should not be disturbed by shuttle traffic, local traffic, and local activities. Roadside activities are one of the disruptions that can cause accidents and need to be analyzed. Blackspot are determined by the Equivalent Accident Number (EAN) method based on accident fatality rate each segment of the road. Roadside activities are grouped into pedestrians and crossers (PED), park and stop vehicles on the side of the road (PSV), slow moving vehicles (SMV), also enter and exit vehicles of activity centers (EEV). Analysis with linear regression is used to calculate the level of impact of roadside activities with accident rates. From 25 segments along Soekarno-Hatta Road, 16 segments are classified as blackspot and 6 segments are still classified as blackspot until 2017. EEV is the highest number that affects the decrease in the number of accidents, PSV for the 2nd number, SV for the 3rd number and PED for the smallest number. Besides the average vehicle speed is only 42,8 km/h due to the high volume of vehicles with an average of 2708 skr/h also the damaged of some segments and poor support facilities of the road.

Abstract

Abstrak Tujuan penelitian adalah melihat pengaruh penambahan bahan difa soil stabilizer terhadap daya dukung dan potensi pengembangan tanah lempung. Tanah lempung berasal dari Lampung Selatan, dibagi menjadi lima variasi penambahan bahan tambah: variasi 1 (tanah asli), variasi 2 (tanah asli ditambah 8% semen dan 0% difa), variasi 3 (tanah asli ditambah 4% semen dan 3% difa), variasi 4 (tanah asli ditambah 6% semen dan 3% difa) dan variasi 5 (tanah asli ditambah 8% semen dan 3% difa). Untuk pengujian CBR, setiap variasi diberikan empat perlakuan yaitu pemeraman empat hari, pemeraman tujuh hari, pemeraman 14 hari, dan pemeraman empat hari dilanjutkan perendaman empat hari. Sedangkan untuk pengujian potensi pengembangan, benda uji direndam selama empat hari sebelum dilakukan pengujian. Hasil penelitian menunjukkan penambahan difa soil stabilizer meningkatkan nilai CBR tanpa atau dengan rendaman untuk semua perlakuan dan menurunkan potensi pengembangan lempung. Dengan demikian dapat mengurangi ketebalan lapisan pondasi struktur perkerasan jalan. Kata kunci: difa soil stabilizer, sifat mekanik, stabilisasi, tanah lempung.  Abstract The objective of this study was to investigate the effect of difa soil stabilizer on the bearing capacity and swell potential of clay. The clay was divided into five variations: variation 1 (clay only), variation 2 (clay plus 8% cement and 0% difa), variation 3 (clay plus 4% cement and 3% difa), variation 4 (clay plus 6% cement and 3% difa) and variation 5 (clay plus 8% cement and 3% difa). For the CBR test, each variation was given four treatments, namely four-day curing, seven-day curing, 14-day curing, and four-day curing followed by four-day soaking. As for the swell potential test, the specimens were soaked for four days before testing. The results showed that the addition of difa soil stabilizer increased the CBR value without or with soaking for all treatments and decreased the clay swell potential, thereby reducing the thickness of the foundation layer of the pavement structure. Keywords: clay, difa soil stabilizer, mechanical characteristics, stabilization
