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

Electromagnetic wave radiation has a very broad spectrum, ranging from extreme low to very high frequencies. Radiation measurements were carried out with the aim of determining exposure to electromagnetic radiation around Palangka Raya University. From the measurement results, it can be seen that the highest intensity of electromagnetic radiation is in the PPIIG building, namely 80 µT, this is due to the influence of the large voltage around the electricity pole. However, this value still meets the ICNIRP quality standards for magnetic field radiation for the general public. Prolonged exposure to electromagnetic radiation can affect the condition of the body. If you are exposed to radiation for too long, the first thing you will feel is nausea and dizziness. The aim of this research is to provide information for the academic community to better understand and minimize the impacts that occur due to radiation exposure in the campus environment and the basis for health policies for the academic community.

Abstract

Limbah minyak jelantah rumah tangga merupakan salah satu permasalahan lingkungan yang sering terjadi di kawasan permukiman, termasuk di Kelurahan Menteng. Sebagian besar masyarakat masih membuang minyak jelantah secara langsung tanpa pengolahan, sehingga berpotensi mencemari lingkungan sekaligus belum dimanfaatkan sebagai peluang ekonomi. Oleh karena itu, kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pengetahuan, keterampilan, dan kesejahteraan ekonomi ibu-ibu Dasawisma melalui pelatihan diversifikasi minyak jelantah menjadi produk ramah lingkungan yang bernilai guna. Mitra kegiatan adalah kelompok UMKM ibu-ibu Dasawisma di Kelurahan Menteng. Kegiatan dilaksanakan melalui lima tahapan utama, yaitu observasi dan identifikasi permasalahan, sosialisasi program kepada masyarakat, pelatihan teknis pengolahan minyak jelantah, pendampingan produksi, serta evaluasi akhir program. Pelatihan dilakukan menggunakan metode praktik langsung (hands-on training) dengan memanfaatkan alat sederhana yang mudah diterapkan oleh masyarakat. Produk yang dihasilkan antara lain sabun cair, lilin aromaterapi, dan produk rumah tangga ramah lingkungan lainnya. Hasil evaluasi menunjukkan bahwa 92% peserta memperoleh pengetahuan baru mengenai pengolahan minyak jelantah, 84% menyatakan siap melanjutkan produksi secara mandiri, dan 76% menilai kegiatan ini berpotensi meningkatkan pendapatan keluarga. Temuan tersebut menunjukkan bahwa pelatihan berbasis praktik efektif meningkatkan kesadaran lingkungan sekaligus membuka peluang usaha baru bagi UMKM rumah tangga. Dengan demikian, kegiatan ini tidak hanya berkontribusi pada pengurangan limbah rumah tangga, tetapi juga mendukung pencapaian Sustainable Development Goals (SDGs), khususnya tujuan 8 (decent work and economic growth) dan tujuan 12 (responsible consumption and production).
