As been coming ages, modern technology integrates into every life aspect including in field survey. Nowadays, one of the modern technology namely Global Positioning System (GPS). The GPS system was first developed by the US Department of Defense used for both military and civilian purposes. This system is designed to provide threedimensional position, speed, and information about world which is not affected by time and weather. Presently, GPS has been widely used by people all over the world who is need information about position, speed or time. To determine the coordinates of points on earth, the receiver requires at least 4 satellites to capture the signal correctly with the coordinates obtained referring to the global datum such World Geodetic System 1984 (WGS'84). GPS is divided into 3 types: Type of navigation or handheld, generally used in battle field or navigation purposes. Some vehicles have been equipped with GPS for navigation aids by adding a map to guide the rider thus rider know which pathway should be chosen to arrived at the destination. GPS mapping is a GPS tool used to calculate an area or create an important route in transit. Type Mapping has an accuracy level between 1-3 meters and mapping types require a base station serving to receive satellite signals and transmit them to a GPS receiver. Geodetic type is the most meticulous and most sophisticated type than navigation or mapping because it has a level of accuracy below 1 meter. The price of geodetic type is most expensive.

In the last few years Palangka Raya City was hit by many points of forest and land fires (Karhutla) that have sprung up intentionally or not sporadically which resulted in smoke and an unpleasant atmosphere which would trigger material losses and of course the health of the surrounding community that inhaled the smoke left over from forest fires and the land. This condition also results in health, economic, social and environmental losses which will certainly hamper the pace of development and the ongoing development of the City of Palangka Raya. The main objective of this research is the use of drones to detect and community preparedness for forest and land fire disasters in areas that have potential for forest and land fires.

The enactment of Law No. 22 of 1999 on Regional Autonomy, which every district / municipality is required to utilize the full potential of the region in order to achieve development targets are not only limited in an effort to increase revenue (PAD), but also efforts to more tangible, namely to improve the welfare of society and one of them is the wealth of art and culture of Central Kalimantan developed as a basis for the tourism development. Central Kalimantan Province has the potential, sources of inspiration and sufficient raw materials in the art works but having problems in the development of them, artists do not have a representative place to introduce and sell the artwork. To introduce an art a facility is needed, that has the function to organize the work of art as well as marketing products and Central Kalimantan province, especially the town of Palangkaraya in dire need of such planning. Art gallery is the right solution for the planning because the gallery can be defined as a room or building that is managed by a permanent institution, serves to collect, preserve, exhibit and sale of works of art.

Peat swamp forests serve as an abundant water catchment area in rainy season and then releases it gradually in dry season. The main function of peat swamp forests are as the hydrology regulator in an ecosystem, and the function will be disrupted when the peat swamp forests have excessive drainage condition. Recently, the peat swamp forests of Central Kalimantan are badly damaged by prolonged exploration without any responsibility to preserve it. One of the damage causes of the peat swamp forests in Central Kalimantan are many canals made when illegal loggers get their harvested wood out to the estuary of nearest watershed. Therefore, it forms canals that drain water with no control. The effect is peat swamp forests will be very dry and trigger devastating fire that cannot be extinguished in a short time. One of the efforts to deal with the problem is by recovering the hydrology condition of peat swamp forests ecosystem through duct insulation using simple dam locally called â€œtabatâ€. The making of tabat is easily designed in order that the implementation is not very hard, and the material selection such as forest wood dominate the construction because the wood will be cracked gradually without disturbing the ecosystem process and restoration principle in peat swamp forests. The modeling result by a computer software of hydraulics shows the increase of water level in canals at 15 to 30 cm and the width of inundation in tabat when the designed flood of two-year return period was modeled to 280.67 km2 and for the period of five years was 306.04 km2 from the target of hydrology restoration of 250 km2.

The capital city of Central Kalimantan, namely Palangka Raya City, almost every year there are always forest and land fires that harm many people both economically, socially and environmentally which will certainly hinder the development of this city, Palangka Raya has a fire-prone area of 33,824 ha. Monitoring forest and land fires with manual field visits which can be very time consuming. To shorten the time and expand the ability to monitor forest and land fires, the use of Unmanned Aerial Vehicles (UAV) or drone images is one solution to map fire-prone areas in all fields. The aerial photography produced by the UAV is processed using the photogrammetric method to produce a responsible aerial photo map covering an area of 41.92 with 17 benchmark points to block fires in the UPR campus forest from spreading.

The making of tabat is easily designed in order that the implementation is not very hard, and the material selection such as forest wood dominate the construction because the wood will be cracked gradually without disturbing the ecosystem process and restoration principle in peat swamp forests. This study was one of the efforts to rescue peat swamp forests by hydrology restoration using a modeling concept with a computer software of hydraulics. The modeling concept used steady flow water surface profile to find out the capacity of cross section to designed flood. After the simulation, tabat modeling was then made to the height of canal. The modeling process resulted in the width of inundation in tabat. The height of water level and the number of tabat were required to optimally inundate the research area. The modeling result by a computer software of hydraulics shows the increase of water level in canals at 15 to 30 cm and the width of inundation in tabat when the designed flood of two-year return period was modeled to 280.67 km2 and for the period of five years was 306.04 km2 from the target of hydrology restoration of 250 km2. The modeling of inundation width in tabat of peat swamp forests will be suggestion for the government of Central Kalimantan Province and the stakeholders in building a big scale tabat.

This study aims to obtain the percentage of coarse aggregate combined between crushed stone and uncrushed stone which produces the optimum compressive strength and elastic modulus of concrete. To achieve this goal, an experimental study was carried out in the laboratory using a cylindrical specimen with a diameter of 150 mm, a height of 300 mm with six variations of the mixture. Concrete mix planning is based on SNI 03-2834-2000 concerning Procedures for Making Normal Concrete Mixture Plans. The test results show that the greatest compressive strength and elastic modulus is produced by a concrete mixture in which all coarse aggregates use crushed stone with a compressive strength value of 10.12 MPa and an elastic modulus of 16413.57 MPa. For concrete mixtures that use a combination of the coarse aggregate of crushed stone and unbroken stone, the largest compressive strength and elastic modulus are produced from a mixture of 80% crushed stone and 20% uncrushed stone.
