Abstract

Ecosystems in Central Kalimantan are generally dominated by peat swamps, including Kereng Bangkirai Village, Sebangau District. Ecotourism is responsible for improving community welfare but still prioritizing the environmental preservation of natural areas found in tourist locations. Education on waste management in the community is still lacking, reflected in the lack of sorting when disposing of household waste to the landfill and residents' habit of burning environmental waste in the form of leaves or dry grass. The Riswandi Farm farmer group uses the results of cutting grass in the Kereng Bangkirai area to be used as compost. However, the limitations of the grass-cutting tools used are an obstacle in producing compost. So it is necessary to apply shredding machine technology to overcome the problem of the amount of organic compost production and produce derivative fertilizer products in other forms.

Abstract

Research on biological materials using dielectric materials has been widely conducted, but currently there are not many studies using electrolyte materials/solutions. The purpose of this study is to determine the relationship between solution concentration and solution impedance value, as well as the relationship between frequency and solution impedance value. This study uses the electrochemical impedance spectroscopy (EIS) technique in Citric Acid (C6H8O7) solution. The results of the study obtained indicate that the impedance value is a complex number with a real part (Z') and an imaginary part (Z''). The impedance value (Z') can be distinguished well in the frequency range of 100 Hz - 1 kHz with a concentration variation of 17.10-5 M -85.10-5 M. At low frequencies, the effect of concentration on the impedance value (Z') cannot be distinguished well, but at high frequencies, the effect of solution concentration on the impedance value can be distinguished well. In the frequency range >100 kHz, the impedance value cannot be distinguished well because the device becomes less sensitive to changes in frequency. This study shows that electrochemical impedance spectroscopy can be used to study the effects of concentration and frequency on the properties of double layers in citric acid solutions.

Abstract

Waste is one of the national problems that will have a direct impact on the environment and social in the community. In Indonesia itself, the open-dumping system is still the system applied in most landfills in Indonesia. The system is relatively simple and easy, but it is not free from many shortcomings, namely the emergence of leachate flows, especially in provinces/regions that have a dense population. The shortcomings of the system give urgency to the research conducted, namely analyzing and evaluating the distribution of leachate water in the Palangka Raya City Landfill using the self-potential method, especially with a fixed-based configuration. The purpose of this research is to analyze the potential difference value and its relationship to leachate flow, make a map of leachate distribution and flow and analyze the social environmental impact around the Palangka Raya City Landfill. The results showed that the anomalous distribution was blue to purple with a range of values around -4mV to -12 mV, a low potential difference value that can be interpreted as an accumulation of fluid flow or leachate below. Based on the results of data processing in the field, this shows that the distribution of anomalies with low values is on the side that leans closer to the garbage and away from residential areas. The water flow flows from the southwest to the northeast. The accumulation of fluid flow is also trapped in an area that is lower than its surroundings

Abstract

Kelakai (Stenochlaena palustris (Burm F.) Bedd) is a type of fern that grows in peat swamp areas or commonly called wetlands. Kelakai leaves contain secondary metabolites, namely flavonoids, which are effective as antioxidants and counteract free radicals. The purpose of this study was to determine whether the extract of kelakai leaves (Stenochlaena palustris (Burm.F.) Bedd) has sunscreen protection activity.UV radiation or known as ultraviolet consists of 2 types, namely: UV-A and UV-B, the letter A in UV-A means "Aging" with a wavelength of 320-400 nm can penetrate the dermis which causes pigmentation, and the letter B in UV-B means "Burning" with a wavelength of 290-320 nm and can penetrate the outermost layer of the skin (epidermis) whose effects can be seen directly in the form of erythema. The SPF value indicates how many times a person's skin protection is doubled so that it is safe under the sun without experiencing erythema, the higher the SPF value of a sunscreen, the better its protection activity. Based on the SPF value data obtained, it shows that the ethanol extract of kelakai leaves can function as an active ingredient in sunscreen because it is proven to have quite high activity and SPF value from minimal protection to ultra protection.

Abstract

Household waste tends to end up in landfills as waste and can damage the environment, but with good management, it can be processed into materials with economic value. Waste materials such as vegetable waste or fruit peels can be processed into a multipurpose eco-enzyme liquid. Eco-enzyme is an organic compound in the form of a complex solution produced from the fermentation process of waste materials in the form of fruit and vegetable peels. How to make it is very easy and can be done by anyone. Because of its content, eco enzyme has many ways to help the natural cycle such as cleaning polluted water. This eco-enzyme can be used as an ingredient in making liquid antiseptic soap. This liquid antiseptic soap is the right solution to reduce water pollution in the environment. This community service activity was carried out to provide insight to mothers on increasing the utility value of organic waste through the application of eco-enzyme as a raw material for making antiseptic soap. Based on the results of organoleptic tests, the antiseptic soap produced has an aroma, color, moisture, viscosity, smoothness, and amount of foam that is liked by the community. This is proven by the organoleptic test, where the average percentage of very like and like was 100%.
