Tanah merupakan dasar dari suatu struktur atau konstruksi, baik itu konstruksi bangunan maupun jalan raya. Sifat-sifat tanah yang buruk atau kurang menguntungkan bila digunakan untuk suatu bangunan atau konstruksi antara lain, plastisitas yang tinggi, kekuatan geser yang rendah, dan potensi kembang susut yang besar. Seperti tanah lempung Desa Mintin yang memiliki nilai CBR dan UCS yang rendah karena dominan butiran halus sehingga mudah dipengaruhi oleh air. Guna mengatasi permasalahan yang ada pada tanah lempung ini, akan dicoba stabilisasi dengan menggunakan semen dan ditambah matos sebagai bahan kimia dan diharapkan mampu memperbaiki dan memenuhi syarat teknis. Pada prosedur penelitian ini dibagi menjadi 3 tahap yaitu penelitian awal meliputi analisa saringan, dan indeks plastisitas, setelah diketahui bahwa tanah tersebut tanah berbutir halus maka dilakukan penelitian kedua yaitu menambahkan campuran pasir 50% terhadap berat isi kering tanah kemudian dilakukan pengujian plastisitas (PI) ≤ 10%. Setelah didapatkan nilai PI ≤ 10% maka dilakukan penelitian tahap akhir yaitu penambahan semen 10% dan campuran matos 0, 4, 8 dan12% terhadap berat isi kering tanah pasir kemudian diuji CBR dan UCS. Hasil penelitian menunjukan bahwa stabilisasi semen ditambah matos dapat memperbaiki sifat fisik dan mekanik tanah lempung, pada sifat fisik berat volume, kadar air, berat jenis, dan batas-batas Atterberg mengalami penurunan setelah dilakukan stabilisasi. Sementara, pada sifat mekanik tanah lempung menjadi semakin baik. Dari hasil campuran semen 10% dan campuran 0, 4, 8, dan 12% matos, campuran yang paling baik terdapat pada 4% penambahan matos untuk nilai CBR, sedang untuk nilai UCS campuran yang paling baik terdapat pada 8% penambahan matos.

Jalan Kinibalu Kota Palangka Raya memiliki tipe jalan tak terbagi yaitu: Jalan perkotaan dua-lajur dua-arah. Pengguna jalan sebagian besar adalah pelaku transportasi lokal dalam kota yang dominan menggunakan kendaraan pribadi, dan sebagian dilayani angkutan umum. Sebagian ada juga yang berjalan kaki di sekitar ruas jalan tersebut. Penelitian ini bertujuan menganalisa ruas jalan Kinibalu untuk mengatasi kinerja jalan tersebut. Data yang digunakan untuk keperluan analisis tersebut digolongkan menjadi dua yaitu data primer diperoleh dari survey geometrik persimpangan, survey arus lalu-lintas, dan survey hambatan samping dan data sekunder berupa peta lokasi dan data jumlah penduduk. Analisis data untuk ruas jalan kota menggunakan Manual Kapasitas Jalan Indonesia (MKJI, 1997). Berdasarkan hasil dari analisis terhadap ruas jalan Kinibalu Kota Palangka Raya dengan menggunakan MKJI 1997, dapat disimpulkan bahwa hambatan samping yang terjadi pada jalan Kinibalu Kota Palangka Raya termasuk kelas hambatan samping tinggi dengan jenis hambatan samping yang paling dominan yaitu kendaraan parkir atau berhenti dan pada siang hari terdapat PKL (pedagang kaki lima) di sekitar ruas jalan. Akan tetapi ruas jalan Kinibalu tersebut masih layak berfungsi dan terjadinya kemacetan hanya pada saat jam puncak puncak (peak hour) berlangsung saja. Untuk mengatasi hal tersebut, dapat di berikan tanda rambu dilarang parkir di sekitar jalan, serta pemeliharaan zebra cross yang masih ada.

The Balikpapan - Samarinda toll road is one part of the trans Kalimantan toll road that arrived currently under construction. The construction of this toll road uses rigid pavement. Road construction This toll road by the East Kalimantan Provincial Public Works Department requires a minimum flexural strength of 45 kg / cm² for 28 days of concrete age. The purpose of this study is to study flexural strength concrete on the rigid pavement of the Balikpapan-Samarinda toll road based on the planning of concrete mixes at field. This study uses experimental methods in the laboratory. Credit samples are made based on concrete mix planning in the field and testing in the laboratory. The sample as many as 24 pieces for a cylinder size of 15 x 30, and 12 pieces for blocks measuring 15 x 15 x 60, which will remain at the age of 7, 14, 21 and 28 days. The results of the strong test on the cylinder is obtained at 382 kg / cm2, 27% bigger than planning, and flexural strength in the beam of 53.48 kg / cm2, 18% greater than requirements. So it can be concluded that the pavement work is rigid on the Balikpapan-Samarinda toll road Has been in accordance with the provisions stipulated by the East Kalimantan Provincial Public Works Department.

Clay soils generally have low CBR and UCS values. Has poor characteristics. In Central Kalimantan the prices of CBR and UCS are low. The soil of clay by its predominance is fine grain easily by air. Some efforts to improve the soil are carried out by stabilizing the soil. One of the clay stabilizing ingredients that can be used is salt. The use of salt as a soil stabilizing agent can provide better benefits compared to other ingredients such as chemicals, sand and semen. The aim of the study was to determine the values of CBR and UCS Soil in Central Kalimantan before and after stabilization using salt. The study was conducted at the Land Mechanics Laboratory of the University of Muhammadiyah Palangkaraya. Samples of clay soil will be given in 6 (six) Regencies in Central Kalimantan Province. Tests carried out on clay are CBR tests and tests before and after stabilization with salt. The salt mixture released is 5, 10,15,20,25% and 30% of the dry weight of the clay. Based on the results of the study indicate that the original land CBR value between 3.90% to 4.75%, can be referred to as land that has a poor / low carrying capacity. Then after stabilizing 5% to 15%, the CBR value increased to reach 5% to 9%. However, after being mixed with salt as much as 20% to 30%, the soil CBR value is adjusted significantly. From this it can be explained that the CBR value reaches the maximum value with a salt rate of 10% to 15% of the weight of the soil.

In 2015 the total area of oil palm plantations in Kalimantan reached 3.47 million Ha with a production of 8.12 million tons per year. Solid waste is in the form of fresh fruit bunches and palm shells. The result of combustion of oil palm shell waste in the form of boiler crust ash is a waste that has chemical elements SiO2, Al2O3, and CaO, with the content of these compounds can affect the strength of the concrete and can increase its strength. In this study, the quality of the concrete mix planned at 28 days is 23 MPa. Concrete testing included compressive strength tests carried out at 3 days, 7 days, 14 days, 28 days, 42 days and 56 days. Before making concrete samples, the mortar compressive strength is tested first by varying the boiler crust ash content by 0%, 15%, 25%, 35%, and 50% to obtain the optimum mixture. Based on the results of the analysis of compressive strength mortar obtained the optimum mixture of 15% for the manufacture of concrete that will be compared with normal concrete. The compressive strength of concrete with the optimum mixture at 28 days is 24.44 Mpa more than the compressive strength of the 23 Mpa plan. Concrete that has the highest compressive strength occurs at the age of 56 days is concrete with the normal mixture with a compressive strength of 34.44 Mpa higher than the compressive strength of concrete with an optimum mixture of 15% boiler crust ash which is 28.51 MPa.

In analyzing the comparison of the cost of acceleration with the acceleration time used by the method Time Cost Trade Off. The analysis is done by using / shortening (crashing) time of implementation by using an alternative to increase working hours (overtime) for 3 hours. With apply the TCTO analysis, the implementation of the construction of the Sei Hanyu Bridge project after its duration performed calculations using the crash duration method, it was found that the time needed to accelerate the construction of the Sei Hanyu Bridge in Kapuas Regency for 1038 calendar days(148 weeks), can be accelerated 44 days from the original planning 1082 calendar days (155 weeks). With the acceleration of the completion of the construction of the Sei Hanyu bridge in Kapuas Regency, an additional fee of Rp. 175,160,710.43 is required with an additional cost (cost slope) of Rp 3,980,925.24 per day for 44 days, so the optimal costs needed to accelerate the construction of the Sei Hanyu bridge in Kapuas Regency was Rp. 45,102,729,928.11 originally planned for Rp.44,927,569,217.68
