PET (Polyethylene Terephthalate) plastic bottle waste is a material that takes a long time to decompose and will accumulate in the world for a long time. Therefore we need the utilization of the plastic waste. One way to reuse PET plastic bottle waste is to use it as an additive to the concrete mixture. The purpose of this study is to determine how much increase in the compressive strength of concrete to the addition of shredded PET plastic waste at 28 days of concrete. The variations in the addition of 0%, 0,2%, 0,4%, 0,6%, 0,8%, and 1% to the volume of concrete cylinders with 3 samples of concrete variations each. The results showed that the concrete with the addition of PET fibers by 0.2% experienced an increase in the compressive strength value of 1.31% from the compressive strength of normal concrete which was originally 22.251 MPa to 22.650 MPa. While the variation in the percentage of PET 0.4%, 0.6%, 0.8% and 1% decreased the compressive strength of the concrete. In PET fiber concrete 0.6% and 1.0%, although there is a decrease in the average compressive strength of the concrete, the value obtained exceeds the compressive strength value of the concrete plan, which is 20 MPa.
Palangka Raya is a city where almost a part of the area is peatland with peat water with an acidity level of around 4.0 - 5.0 which can make concrete become porous and cause damage. This study is to determine the effect of peat water, Kahayan river water, and PDAM water on the compressive strength of concrete. In this study, the immersion of concrete samples was carried out for 28 days and 60 days. The measurement results are known that the pH of peat water is 4.0 while the pH of Kahayan river water and PDAM water is 5.0.From the results note that in the 28 days immersion, peat water concrete has increased in compressive strength while concrete in Kahayan river water and PDAM water has decreased in compressive strength. However, during the 60 days immersion the peat water concrete decreased in compressive strength to 20,638 MPa (17.31%). Whereas the Kahayan river water and PDAM water in the 60 days immersion experienced an increase in compressive strength values of 31,687 MPa (26.96%) and 27,696 MPa (10.98%). From these results, it can be concluded that the Kahayan river water with pH = 5.0 does not make the concrete lose its strength and can survive in an acidic environment.
The city of Palangka Raya has these peatlands spread across several regions including populated areas. This needs special attention in the world of concrete construction because the peatland has peat water with a high level of organic matter, low acidity (pH) which results in acidic water. The acidity of peat water will cause problems in concrete construction because it will affect the physical and mechanical properties of concrete which will make the concrete corrosive. This research method is by making 27 K-250 concrete samples, each of which three examples will be immersed in peat water, Kahayan river water, and tap water for one month, two months and three months. The results showed that the concrete soaked in peat water had the most significant decline compared to the concrete soaked in Kahayan river water and tap water, which was 8.798% of the planned concrete compressive strength of 250 kg / cm2 while the concrete with river water immersion decreased by 5.882% and tap water immersion 2.966% from the planned concrete compressive strength of 250 kg / cm2.
During this time to get the value of California Bearing Ratio (CBR) planners will conduct field tests and/or laboratory tests. This takes time and is relatively large. For this reason, it is needed a practical matter or formulation about the relationship between soil parameters so that planners do not need to test the overall soil parameters. This study aims to obtain a graph or correlation of the Plasticity Index (PI) with California Bearing Ratio (CBR) for clay soils in the Palangka Raya region. Clay soil samples were taken at 3 (three) locations in the City of Palangka Raya. Based on the results of tests on several samples obtained the largest CBR value in soil samples from Tangkiling village which reached a value of 6.56%. While the lowest CBR value obtained from the village of Kereng Bengkirai is 3.14%. For the PI value, the biggest value obtained in Bukit Rawi village is the largest, namely 20.54% and the smallest PI value obtained in Tangkiling village is 9.01%. In general, it can be concluded that the CBR value of clay is inversely proportional to the value of PI. Wherein it is known that the greater the CBR value, the smaller the PI value and vice versa. The overall correlation results of the PI value (plasticity index) to the CBR (California Bearing Ratio) obtain the correlation results using the linear graph CBR = -0.28383 PI + 8,9843. While the correlation value based on analytical calculations obtained CBR = -0,3006X + 9,0190. This test shows that the correlation value has a very high relationship when viewed from the benchmark correlation results (R = 0.80-1.00). The results of the correlation value using linear regression graphs worth R = 0.8489 and using analytical correlation methods worth R = 0.9283. So the final result of this study is to look for a relationship between PI values and CBR values. Then for the value of R is taken the smallest value that is R = 0.8489.

Yasmin Mother and Child Hospital in Palangkaraya City is one of the Class C Hospitals in Central Kalimantan. Yasmin Hospital has become one of the most visited hospitals every day. During visiting hours there was an increase in the need for parking spaces at Yasmin RSIA, so that vehicles that would not use the parking area were not accommodated. This study aims to evaluate the capacity of the parking lot at the RSIA Yasmin Palangka Raya City and provide suggestions for improvement to the Yasmin RSIA. Primary data were obtained from direct observations which included measurements of the number of parking lots, parking area, time count and circulation of the number of vehicles. Furthermore, the data were analyzed to obtain parking characteristics which include parking volume, parking accumulation, parking duration, parking change, parking capacity, and parking index. Based on the results of the analysis, the maximum accumulated vehicle parking occurs on Monday, the motorcycle parking index exceeds 100%, meaning that parking needs exceed normal parking capacity. The proposed improvement is to use the basement as a parking lot to increase the capacity of parking spaces and to arrange parking patterns and parking circulation

Peat is a type of soil that is formed from the accumulation of half-decaying plant debris, therefore, the content of organic matter is high. (Wikipedia, 2016). The fires of peatlands in Central Kalimantan in 2015 were very severe when compared to previous years. Almost all forests or land experience fires. Land fires do not only occur in forest areas but also within the city of Palangka Raya itself. This is not only triggered by the deliberate burning of land, but also due to natural factors (trees that dry out), strong winds, and also human negligence itself (such as removing cigarette butts in dry forest areas). As a result of extensive forest fires, resulting in smog and causing air pollution which inhibits air and land flight paths, making the prices of basic commodities in Palangka Raya move up. For this reason, it is necessary to hold awareness campaigns on fire prevention on peatlands to the community. In this socialization, information is given to the community about the causes of land fires, how to prevent and overcome them. Based on the results of the socialization, the community better understood the causes of land fires, prevention methods and how to overcome them, so that it was expected to prevent or unravel the occurrence of land fires in the coming years.
Banyaknya persimpangan dikota Palangka Raya dengan jarak antar simpang yang pendek terkadang menimbulkan permasalahan tersendiri, dimana kendaraan terkadang harus selalu berhenti pada tiap simpang karena selalu mendapat sinyal merah. Penelitian ini bertujuan menganalisa simpang di jalan Garuda-Rajawali dan jalan Tingang-Rajawali, dengan mengkoordinasikan kedua simpang untuk mengurangi antrian dan tundaan. Perencanaan waktu siklus yang didasarkan pada kondisi terjenuh saaat eksisting. Perencanaan dilakukan dengan memperhatikan teori koordinasi persimpangan dan rumus dalam MKJI 1997. Diharapkan waktu siklus baru dapat memberi kinerja simpang lebih efektif. Merencanakan koordinasi antar kedua simpang dari waktu siklus baru yang telah didapat dengan menggambil waktu siklusterpanjang dari kedua simpang. Dari hasil penelitian diperoleh waktus siklus Simpang I = 98 detik dengan masing-masing pendekat, pendekat (Utara=11 detik, Timur= 21detik, Selatan=12 detik, dan Barat = 29 detik). Sedangkan pada simpang II = 113 detik dengan masing-masing pendekat, pendekat (Utara=12 detik,Timur=31 detik, Selatan = 12 detik, dan Barat = 34 detik). Dari hasil perbandingan waktu siklus setelah analisis, diketahui waktu siklus Simpang II (c = 113 detik) lebih besar dari Simpang I (c = 98 detik) dengan selisih waktu 15 detik. Maka kedua simpang dapat dikoordinasikan dengan mengambil waktu siklus terpanjang dari kedua simpang tersebut, yaitu c = 113 detik. Waktu tempuh dari simpang I ke simpang II membutuhkan waktu sekitar 61,42 detik, dengan t=0 pada waktu hijau pertama fase ke 2 pada simpang I dan t=61,42 detik merupakan waktu hijau pertama fase ke 2 pada simpang II.
Jalan Temanggung Tilung is a 2/2 UD type road (two undirected two-way lanes) with a road width of 5.5 meters, which is a connecting road between two major roads, namely the RTA road. Milono and the path of G. Obos. Over time, the volume of traffic through these roads increases every year, plus roadside activities that also increase cause congestion at several points of the way. To overcome this problem, the local government carried out road widening to increase the capacity and level of road services. The study was conducted to determine the amount of traffic volume, performance, service level of the Temanggung Tilung road section at peak traffic hours before and after road widening. Data retrieval is done by the direct survey to the field to obtain primary data in the form of geometric road data, two-way traffic volume data, and side obstacle data. Performance analysis refers to the 1997 Indonesian Road Capacity Manual (MKJI) for urban roads. From the results of data processing, before increasing the road (Type 2/2 UD), the traffic volume that passes through the path is 842 pcs/hour and after road widening (Type 4/2 UD) the traffic volume for two directions is 973 pcs/hour, with route A equaling 528 pcs/hour and direction B equaling 445 pcs/hour. Based on the analysis of road performance before road enhancement, the capacity = 2551 pcs/hour, saturation degree = 0.331, and the service level of the two-way road are level B. Based on the analysis of the performance of the way after increasing the way, the direction capacity A = 2686 pcs/hour and direction B = 2674 pcs /hour, saturation degree for direction A = 0.196 and direction B = 0.166, service level for road direction A and direction B increase to level A
