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

Praktikum mikroskopis pada pelajaran biologi di sekolah sering kali menghadapi kendala terkait dengan ketersediaan preparat yang berkualitas. Untuk itu, pelatihan pembuatan preparat permanen jaringan tumbuhan bertujuan untuk meningkatkan keterampilan guru dalam membuat preparat mikroskopis menggunakan teknik parafin. Kegiatan ini diselenggarakan di Gedung Pusat Pengembangan IPTEK dan Inovasi Gambut (PPIIG), Universitas Palangka Raya, dengan diikuti oleh sembilan orang guru biologi dari sekolah mitra sasaran. Pelatihan dimulai dengan pemaparan materi mengenai mikroteknik tumbuhan, yang mencakup langkah-langkah pembuatan preparat, mulai dari fiksasi, dehidrasi, penyayatan, pewarnaan, hingga pemasangan preparat. Para peserta juga diberikan kesempatan untuk praktik langsung pembuatan preparat segar dan awetan, serta teknik pewarnaan dan mounting menggunakan mikrotom dan safranin. Kuesioner pra dan pasca pelatihan digunakan untuk mengevaluasi pemahaman dan keterampilan peserta, yang menunjukkan peningkatan signifikan setelah kegiatan. Sebelum pelatihan, tidak ada peserta yang memahami atau memiliki keterampilan dalam pembuatan preparat permanen jaringan tumbuhan. Namun, setelah pelatihan, seluruh peserta berhasil menguasai teknik tersebut. Evaluasi ini menunjukkan bahwa pelatihan ini efektif dalam meningkatkan kompetensi praktis guru, yang diharapkan dapat meningkatkan kualitas praktikum biologi di sekolah. Ke depan, pelatihan ini memiliki potensi untuk dikembangkan lebih lanjut dengan topik-topik tambahan seperti perawatan mikroskop dan teknik kultur jaringan.

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%.

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

Landslides occur as a result of a geological process caused by the displacement of rock or soil masses. In general, landslides are caused by shifting soil and excessive water content due to high rainfall. One of the processes that occur in rivers is sedimentation With the entry of sediment into the river flow, it will result in increased river surface flow and deposition which causes siltation of the river. This siltation will greatly affect the capacity of the river when the rainy season arrives, because it can cause floods. For this reason, assistance and training are needed to increase community knowledge about the use of Internet of Things (IoT) based monitoring system tools around the Kahayan river basin. IoT is a technology that allows smart objects, things, and machines to be connected via the internet so that data can be received in real time. The people of Pahandut Village were enthusiastic in participating in the socialization activities provided and felt the benefits of increasing knowledge starting from an understanding of the Internet of Things and the use of monitoring system tools for land shifts. Based on the evaluation results, it is known that participants have increased knowledge and insight into the Internet of things and its application in this case the soil shift monitoring system tool which will later be installed in residential areas around the watershed.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh radiasi gelombang elektromagnetik handphone redmi 9A terhadap kandungan protein daging sapi dan pengaruh lama paparan dan jarak radiasi dari telepon seluler redmi 9A terhadap daging sapi. Sampel daging sapi diradiasi dengan menggunakan radiasi dari gelombang elektomagnetik handphone redmi 9A dengan variasi lama paparan tanpa radiasi atau 0, 60 dan 90 menit dan variasi jarak sumber radiasi terhadap objek 2 dan 7 cm. Perhitungan kandungan protein daging sapi diukur menggunakan metode khedjal. Hasil penelitian menunjukan bahwa pada jarak 2 cm dengan lama paparan 60 menit nilai protein yang diperoleh 16,259, 90 menit nilai kadar proteinnya sebesar 17,78 dan pada jarak 7 cm ketika diberikan paparan radiasi selama 60 menit kandungan sebesar 22,79 dari 17,415. Intensitas radiasi yang dihasilkan oleh handphone redmi 9A berpengaruh terjadinya penurunan dan peningkatan kandungan protein daging sapi. Variasi lama paparan dan jarak tidak bepengaruh pada lama paparan 90 menit dengan jarak 2 cm hal ini dikarenakan radiasi yang didapatkan dari objek semakin banyak tetapi kandungan protein yang dihasilkan meningkat, sedangkan pada lama paparan ke 90 dengan jarak 7 cm berpengaruh yang mana semakin jauh objek radiasi radiasi yang didapatkan semakin semakin sedikit dan kandungan protein menurun.
