Mining of split rock or ultramafic igneous rock, located in the Awangbangkal area, Karangintan District, Banjar Regency, South Kalimantan Province, causes steep slopes. The formation of the Meratus Mountains is an oceanic bedrock that is exposed to the earth's surface and is mined by local residents using simple tools or semi-mechanical equipment carried out by the company. Positive impacts arise but negative impacts will also build up over time. Day by day more dangerous slopes were formed. The local government became worried because it was dangerous. This writing is compiled based on the results of direct measurements in the field using the Theodolith unit. The measurement results are processed using Autocad Landesktop 2009 software. The analysis is by classifying the slope of the formed slopes according to the data that is already in digitized form. The result is a dangerous area on the east side, because it has a slope of 25% -45% (steep). Although from a geological point of view this area is stable because it is formed by igneous rocks, from the local government side this is a concern for the people who do work in the area.

The development of cases infected with the COVID-19 virus in Indonesia continues to increase. COVID-19 is a member of the corona virus family that has spread throughout the world. The COVID-19 Main protease is considered a suitable target for drug design against SARS infection because it plays a role in the processing of polyproteins required for the reproduction of the coronavirus. Eucalyptus are claimed to be able to ward off the COVID-19 virus. Therefore it is necessary to evaluate the content of eucalyptus compounds against Main proteases by docking studies. Based on the results of research conducted using the active site on the Main protease, it is known that eucalyptus (-)-globulol, epiglobulol, and ledol compounds have free energies of -7.23 kcal/mol, -7.91 kcal/mol, and -7.39 kcal/mol, respectively. Remdesivir as a therapeutic drug for COVID-19 has a free energy of -7.67 kcal/mol. These three compounds bind to the amino acid Glu166 as remdisivir with the best binding affinity on the active site of the Main protease. So these three compounds have the potential to inhibit the COVID-19 virus.

Subur Makmur Village is an area where the availability of clean water is difficult, especially during the dry season. One of the sources of water that can be used by the villagers is groundwater. However, to obtain groundwater, it is necessary to drill wells and investigate the aquifer layer first. This study aims to obtain an overview of the subsurface layers based on the resistivity properties of the rock, so that the aquifer layer can be identified and can determine the exact location of the drill point in the prospective aquifer position that may be encountered. The geoelectric method is the most efficient method for detecting aquifer layers. It uses two types of configurations, namely, the Wenner and Wenner-Schlumberger configurations where the number of geoelectric paths is one path. The length of the track used is 540 meters, the number of electrodes is 28 with the spacing between the electrodes is 20 meters. The resistivity cross section for both configurations, obtained resistivity values of 11 - 140 Ohm meters. Composed of 2 (two) rock units, namely graywacke sandstone rock units. Consists of graywacke sandstones with claystone inserts. Density value ≥ 40 Ohm meter. Hydraulic properties, small porosity, small permeability, the potential for groundwater in this unit is small. The position of this unit is at a depth of 40 m. In the cross section, the resistivity is yellow - red. The second rock unit comprising this trajectory is the alteration claystone unit consisting of claystone containing bolders of sandstone / igneous rock. Resistivity value ≤ 40 Ohm meter. The position of this unit is on the Surface to a depth of 40 m. Hydraulic properties, large porosity with very small permeability, the potential for groundwater is very small. In the cross section of this unit resistivity are colored dark blue, blue and green. From the resistivity cross section, it can be determined the position of the borehole which is effectively located in the length range of the trajectory between 360 - 420 meters.

High population growth and low consumption of carbohydrate sources in Riau Province encourage rice production to be increased. One effort to increase rice production in Bumi Lancang Kuning is to increase productivity through improved planting systems. The research was conducted in the rainy season of 2016 on irrigated and tidal paddy field using Inpari 13 variety, aiming to determine the best planting system in increasing Riau Province rice productivity. Irrigated rice field is located in Dayang Suri Village, Bunga Raya Subdistrict, and tidal land is located in Selat Guntung Village, Sabak Auh Subdistrict, Siak Regency, Riau Province. The three planting systems tested were (1) tiles, (2) Jarwo 4: 1, and (3) Jarwo 2: 1 and two agroecosystems ie (a) tidal land and (b) irrigated land. The treatment was arranged in a randomized block design (RBD) with five replications. Fertilization N, P2O5, and K2O for irrigated land (67.5-60-45) and tides (90-120-60). The parameters observed were plant height and number of tillers 30 and 60 days after planting (DAP), number of grain per panicle, weight of 1,000 grains, and rice productivity (t/ha). The results showed that plant height and number of tillers of 30 DAP were not affected by treatment, while the plant height, number of tillers at 60 DAP, the number of grains per panicle, and the weight of 1,000 grains were affected only by agro-ecosystem. Rice productivity is strongly influenced by agro-ecosystem and planting system. The productivity of rice in tidal land is lower than irrigated land. Compared with tile planting systems, the increased productivity of the Jarwo 2: 1 planting system is higher than the Jarwo 4: 1 planting system. Increased productivity due to improved planting systems in tidal areas is higher than irrigated land.
