Abstract

Saat ini handphone menjadi salah satu kebutuhan primer, handphone merupakan perangkat elektronik yang mampu memancarkan radiasi gelombang microwave. Radiasi yang dipancarakan oleh telepon seluler pada dasarnya kecil, akan tetapi interaksi pengguna dengan waktu yang lama berpotensi menimbulkan gangguan kesehatan bahkan kerusakan pada jaringan atau sel dari tubuh makhluk hidup. Penelitian ini bertujuan untuk mengetahui pengaruh radiasi dan lama paparan gelombang elektromagnetik handphone terhadap kandungan protein daging sapi. Sampel daging sapi diradiasi dengan menggunakan radiasi dari gelombang elektomagnetik handphone dengan variasi lama paparan tanpa radiasi atau 0, 15, 30, 45 dan 60 menit. Perhitungan kandungan protein daging sapi diukur menggunakan spectrometer UV-Vis. Hasil penelitian menunjukan bahwa dengan yang paling berpengaruh terhadap penurunan kadar protein adalah di menit ke 60. Intensitas radiasi yang dihasilkan oleh handphone berpengaruh terhadap terjadinya penurunan kandungan protein daging sapi dimana terjadi penurunan persentase kandungan protein daging sapi yang diradiasi dari keadaan normal seiring bertambahnya lama paparan.

Abstract

Pemanfaatan teknologi nuklir dapat meningkatkan kesejahteraan manusia seperti membantu penyembuhan berbagai jenis penyakit, namun radiasi yang digunakan juga memiliki dampak yang berbahaya apabila terkena paparan terus – menerus. Jenis hewan yang sering digunakan untuk penelitian yaitu Mencit (Mus musculus) dan Tikus (Rattus Norvegicus) karena kemiripan genetiknya dengan manusia, kemudahan pemeliharaan, reproduksi cepat, dan ketersediaan strain genetik yang luas. Dosis radiasi yang relatif rendah dapat menginduksi kerusakan genetik, serta memengaruhi struktur histologi organ. Organ yang paling rentan terhadap kerusakan akibat radiasi pada hewan adalah organ reproduksi, hepar dan ginjal. Paparan radiasi sinar – X dapat menurunkan motilitas sperma dan mempengaruhi struktur histologi testis, sehingga mempengaruhi fertilitas. Radiasi pengion seperti sinar gamma juga dapat menyebabkan kemandulan dan mempengaruhi kesuburan gonad pada hewan. Dari beberapa penelitian yang telah dilakukan pada review  ini, sebagian besar menggunakan ekstrak tanaman untuk mengkaji efek dari pemberian ekstrak tersebut kepada hewan coba yang terkena paparan radiasi.

Abstract

Mastery of science and technology is important in building competitiveness in order to produce value-added products and provide competitive advantages. Mastery of science and technology can be improved through various sciences, one of which is natural science (IPA). Natural science is a collection of knowledge and processes carried out by scientists in conducting investigations to obtain explanations about natural phenomena that occur in everyday life. One step in having the strategy in question is mastering the techniques for presenting material or what is usually called teaching methods. The use of practical teaching aids helps make it easier for teachers to explain a concept to students. Nathania Palangka Raya Middle School is located in the center of Palangka Raya city, Central Kalimantan Province. Based on the survey results, science learning carried out by teachers still uses conventional methods and without the help of learning media. Apart from that, teachers still dominate the science learning process. One way to improve the abilities of teachers and students in the field of science requires training and use of science teaching aids. The result of this training is that students are enthusiastic about participating in activities organized by the service team. In addition, students' understanding of the material taught using science teaching aids is better than without using science teaching aids and also increasing teacher abilities, will contribute to the improvement students' understanding of science concepts

Abstract

Sungai Kahayan, sebagai salah satu sungai utama di Kalimantan Tengah, memiliki peran krusial dalam kehidupan masyarakat setempat. Namun, aktivitas manusia di sekitar sungai ini, seperti pembuangan limbah rumah tangga dan industri, mengakibatkan potensi pencemaran yang signifikan. Penelitian ini menggali variasi spasial dan temporal dari 11 parameter kualitas air Sungai Kahayan selama periode 2021–2023. Hasil analisis menggunakan teknik statistika multivariat,  Analisis Klaster Hierarki (HCA) dan Analisis Komponen Utama (PCA), mengidentifikasi hubungan kompleks antar parameter. Hasil PCA menunjukkan bahwa parameter kualitas air dapat direduksi menjadi dua komponen utama (PC1 dan PC2), menjelaskan sekitar 84,24% variabilitas data. PC1 merepresentasikan tingkat polusi organik dan anorganik, sementara PC2 mencerminkan aspek-aspek kimia dan keseimbangan kimia dalam air. Analisis spasial menggunakan HCA mengelompokkan lokasi pengambilan sampel ke dalam dua klaster utama, menunjukkan perbedaan signifikan dalam kualitas air. Analisis temporal menggunakan MANOVA mengungkapkan perbedaan yang signifikan setiap tahun, terutama pada parameter pH, DO, BOD, NH3-N, TDS, TSS, dan Fe. Kemampuan self-purification Sungai Kahayan dievaluasi melalui analisis tren dengan melibatkan parameter DO, BOD, dan COD. Meskipun terjadi pemurnian diri, sungai belum mencapai zona air bersih pada titik terakhir pengambilan sampel. Penelitian ini memberikan pemahaman mendalam tentang variasi spasial dan temporal kualitas air Sungai Kahayan, serta implikasinya terhadap proses self-purification. Hasilnya dapat menjadi dasar untuk pengelolaan sumber daya air yang berkelanjutan dan peningkatan pemahaman terhadap kondisi ekosistem sungai.

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%.
