Abstract

Asam urat merupakan salah satu radang sendi yang terjadi karena adanya penumpukan kristal asam urat di jari kaki, pergelangan kaki, lutut, dan paling sering di jempol kaki. Kadar asam urat antara pria dan wanita berbeda, dimana asam urat yang normal pada pria berkisar antara 2,5-7mg/dL dan pada wanita berkisar antara 1,5-6mg/dL. Asam urat yang tinggi dapat diobati dengan obat antiinflamasi non steroid seperti ibuprofen, dan sebagainya. Namun dapat juga dicegah dengan menerapkan pola makan sehat dan pola hidup yang sehat. Pengetahuan masyarakat RT 02 RW 06 Lembah Sari masih minim terhadap asam urat. Pengabdian bertujuan untuk mengedukasi dan mendeteksi dini asam urat. Pengabdian ini dilakukan di RT 02 RW 06 Lembah Sari dengan cara pengisian kuesioner pretest, penyampaian materi secara langsung, dilanjutkan dengan sesi tanya-jawab, dan pengisian kuesioner posttest. Hasil pretest dan posttest terkait pengetahuan asam urat didapatkan adanya peningkatan pengetahuan peserta menjadi baik sebesar 46,2%. Pada pemeriksaan dari 4 orang prempuan didapatkan 50% peserta memiliki kadar asam urat yang tinggi, 1 peserta (25%) rendah, dan 1 peserta (25%) normal.

Abstract

Duch Eggplant rich in phytochemicals, such as polyphenols, flavonoids, and carotenoids. Studies have demonstrated the powerful antioxidant activity of these compounds, which can shield body cells from free radical-induced oxidative damage.The aim of this study is to determine the IC50 value of the antioxidant activity present in the skin of the Holland turnip. This study also has implications for human health. Knowing the anti-oxidant skin activity in the inviter allows us to estimate the potential benefits of protecting the body from oxidative damage. 1.1-diphenyl-2-picrylhydrazil (DPPH) is the method employed. This method involves measuring the ability of the extract to neutralize the free radicals in DPPH. We will observe the color changes from purple to yellow and evaluate the free radical's capture capacity based on the degree of color change. The study's findings revealed an IC50 value of 41,019 ppm. The conclusion from the IC50 values obtained is that the methanol extract in the skin of the Dutch teranga has an antioxidant activity that is very strong to counter free radicals.

Abstract

Indonesia merupakan salah satu Negara yang memiliki sekitar 71 varietas kedelai. Kedelai diketahui memiliki kandungan protein yang hampir sama dengan susu sapi. Protein pada kedelai dapat mempernagruhi komunitas mikroba usus dan dapat juga digunakan sebagai prebiotik. Selain kedelai, kurma juga memiliki banyak manfaat bagi tubuh. Bahkan susu kedelai dan kurma dikombinasi diketahui memiliki manfaat bagi kesehatan. Masyarakat RT 02 RW 06 Lembah Sari masih minim terhadap kombinasi pengolahan susu kedelai kurma. Pengabdian bertujuan untuk melatih masyarakat dalam membuat susu kedelai kurma yang berstandar secara mandiri. Pengabdian ini dilakukan di RT 02 RW 06 Lembah Sari dengan cara melatih secara langsung pembuatan susu kedelai kurma yang disertai penyebaran leaflet tentang cara pembuatan susu kedelai kurma, dilanjutkan dengan sesi tanya-jawab, dan pengisian kuesioner terkait kepuasan masyarakat terhadap pelaksanaan pengabdian. Hasil pengabdian didapatkan bahwa masyarakat sangat antusias dengan pelatihan ini dan dibuktikan dengan data dari pengisian kuesioner yang didapatkan bahwa masyarakat sangat setuju dan setuju dengan diadakannya kegiatan pelatihan ini.

Abstract

This study investigates the Brine Shrimp Lethality Test (BSLT) activity of leaf and gall fractions of Syzygium guineensis, a plant known for its traditional medicinal properties. The objective is to evaluate the cytotoxic potential of these fractions using BSLT, which is a reliable method for assessing toxicity. Leaf and gall samples were extracted using n-hexane, ethyl acetate, and ethanol-water solvents. The cytotoxicity was quantified by determining the LC50 values for each fraction. The results indicated that the leaf fractions exhibited LC50 values of 29.45 ppm (n-hexane), 28.33 ppm (ethyl acetate), and 30.57 ppm (ethanol-water). For the gall fractions, the LC50 values were 27.80 ppm (n-hexane), 26.61 ppm (ethyl acetate), and 24.95 ppm (ethanol-water). All fractions demonstrated significant cytotoxic activity, categorizing them as highly toxic. This study highlights the potential of both leaf and gall fractions of Syzygium guineensis as sources of cytotoxic agents, warranting further investigation for therapeutic applications.

Abstract

This study evaluates the adsorption performance of NaOH-activated cassava peel biochar (Manihot esculenta Crantz) for the removal of Pb²⁺ ions from aqueous solutions, with particular focus on the effects of solution pH and contact time. Cassava peel biochar was produced via pyrolysis at 180–350 °C and chemically activated using 0.1 M NaOH. Surface functional groups and morphology were characterized using Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy–Energy Dispersive X-ray (SEM–EDX). Batch adsorption experiments were conducted by varying solution pH (3–8) and contact time (30–120 min), while Pb²⁺ concentrations before and after adsorption were analyzed using Atomic Absorption Spectroscopy (AAS). The results showed that solution pH significantly affected Pb²⁺ adsorption, with the highest adsorption capacity of 9.94 mg/g achieved at pH 5. Contact time also influenced adsorption performance, and the optimum condition was obtained at 90 min, yielding a maximum adsorption capacity of 9.94 mg/g. These findings indicate that NaOH-activated cassava peel biochar exhibits stable and effective Pb²⁺ adsorption under slightly acidic conditions and moderate contact time, highlighting its potential as a low-cost and environmentally friendly adsorbent for Pb²⁺ removal from contaminated wastewater.
