Abstract

Air adalah sumber daya alam yang dibutuhkan untuk kelangsungan metabolisme manusia dan semua makhluk hidup. Keberadaan polutan dalam air, seperti zat warna dari industri tekstil telah menjadi masalah serius yang mengancam lingkungan dan kesehatan manusia. Pentingnya menjaga keberlanjutan sumber daya alam, terutama air, telah memicu penelitian dalam mengatasi pencemaran air oleh polutan seperti zat warna dari industri tekstil. Dalam konteks ini, teknologi enzim terinkorporasi dalam membran muncul sebagai solusi inovatif. Membran enzim menggabungkan efisiensi teknologi membran dalam pemisahan molekul mikro dengan kemampuan enzim mengoksidasi senyawa organik kompleks, termasuk zat warna. Lakase, sebuah enzim multitembaga yang umumnya ditemukan pada tumbuhan, serangga, dan jamur, telah digunakan untuk mengurai zat warna sulit dihilangkan. Penggunaan membran terinkorporasi dengan enzim lakase telah membawa terobosan signifikan dalam sistem filtrasi air. Lakase tidak hanya efisien dalam memisahkan zat warna, tetapi juga ramah lingkungan karena menggunakan reaksi biokimia alami tanpa bahan kimia tambahan yang merusak ekosistem air.

Abstract

Methylene blue in the environment can disrupt the ecosystem because it does not decompose easily. Therefore, this research aims to oxidize methylene blue using an electrochemical oxidation method. The electrochemical oxidation of methylene blue was successfully carried out using carbon electrodes from battery waste. The influence of pH value and electrolysis time was successfully investigated using a UV-Vis spectrophotometer, and the decreased absorbance (DA(%)) was also analyzed. Based on the results, the optimum pH for electrochemical oxidation with a carbon electrode is at pH 1. It was possible to reduce the absorbance at this pH with a decreased absorbance of 56%. There was a decrease in absorption in the UV and visible regions. The optimum time for methylene blue electrochemical oxidation was 15 minutes, with a decreased absorbance percentage at 100%. The electrochemical oxidation method is simple and easy to use. This finding can be an excellent and effective wastewater treatment method.
Peningkatan Kemandirian Kesehatan Masyarakat melalui Produksi Herbal Berbasis Tanaman TOGA Kearifan Lokal oleh Ibu-Ibu PKK Desa Bahu Palawa Pasaribu, Marvin Horale; Manurung, Tety Wahyuningsih; Surbakti, Ranintha Br.; Ariefin, Mokhamat; Oktaviani, Revalina; Syaputra, Noor Angga

Abstract

Background: Pemanfaatan Tanaman Obat Keluarga (TOGA) sebagai bahan baku jamu tradisional berpotensi meningkatkan derajat kesehatan sekaligus membuka peluang ekonomi bagi masyarakat desa. Namun, keterbatasan pengetahuan dan keterampilan ibu-ibu PKK di Desa Bahu Palawa dalam mengolah TOGA menyebabkan pemanfaatannya belum optimal. Kegiatan pengabdian masyarakat ini bertujuan meningkatkan kemampuan peserta dalam memproduksi jamu serbuk jahe dan berbagai variasi wedang seduh berbasis kearifan lokal. Metode: Program dilaksanakan melalui tahapan sosialisasi, pelatihan, praktik demonstrasi, serta evaluasi pengetahuan dengan pre-test dan post-test, dilengkapi dengan uji organoleptik produk. Peserta dilatih mulai dari persiapan bahan, teknik pengeringan menggunakan oven dryer, formulasi komposisi bahan, hingga pengemasan produk akhir. Hasil: Evaluasi menunjukkan peningkatan signifikan pemahaman peserta, dengan nilai rata-rata pre-test 32,3% meningkat menjadi 91,0% pada post-test. Uji organoleptik juga memperlihatkan penerimaan yang tinggi, di mana 80–90% responden menyatakan suka hingga sangat suka terhadap warna, rasa, dan aroma produk jamu yang dihasilkan. Produk utama berupa jamu serbuk jahe, wedang hangat menyegarkan, wedang rempah pahit manis, dan wedang siru biru dinilai memiliki manfaat kesehatan yang relevan, seperti menjaga daya tahan tubuh, membantu pencernaan, dan mendukung kesehatan jantung. Kesimpulan: Kegiatan ini berhasil meningkatkan pengetahuan dan keterampilan ibu-ibu PKK dalam mengolah TOGA menjadi produk herbal bernilai tambah. Selain berkontribusi pada kemandirian kesehatan keluarga, program ini juga membuka peluang usaha desa berbasis kearifan lokal yang berkelanjutan.

Abstract

The demand for efficient and stable lithium-ion batteries has driven research on advanced polymer electrolyte membranes (PEM) with improved ionic conductivity. This study investigated imidazole and its derivatives as additives in PEM to enhance battery performance. Using Density Functional Theory (DFT) with the def2-TZVP basis set, key quantum parameters such as HOMO-LUMO energies, energy gap (?Egap), electronegativity (?), softness (?), electron transfer fraction (?N), and net electrophilicity (??) were analyzed. Results showed that imidazole derivatives with electron-withdrawing groups, like acrylate and tosyl, had lower ELUMO and smaller ?Egap, improving lithium ion (Li?) interactions and mobility within the polymer matrix. Additionally, compounds with high ? and ?, such as BTIM and BZIM, enhanced ion stabilization and transport, leading to better electrolyte performance. Thus, modifying imidazole structures through specific substitutions is a promising approach to optimize PEM, supporting the development of more efficient and stable lithium-ion batteries.

Abstract

The increasing demand for natural UV-protective agents has led to the exploration of plant-based bioactive compounds. Yellow root (Arcangelisia flava) extract is traditionally used in medicine and contains flavonoids, alkaloids, and terpenoids with potential photoprotective properties. This study aimed to characterize the chemical composition of A. flava extract and evaluate its UV-absorbing properties using UV-Vis and FTIR spectroscopy. The extract was obtained through maceration with ethanol, followed by spectroscopic analysis. The UV-Vis spectrum (200–400 nm) revealed multiple absorption peaks, particularly at 270 nm, 292 nm, 306 nm, 340 nm, 354 nm, 360 nm, and 396 nm, indicating the presence of UV-absorbing compounds. FTIR analysis confirmed the presence of hydroxyl (-OH), carbonyl (C=O), and aromatic (C=C) functional groups, which are characteristic of flavonoids and other bioactive compounds. These findings suggest that A. flava extract has potential as a natural UV-protective agent. Further studies on compound isolation, fractionation, and photostability assessments are required to optimize its purity and effectiveness in sunscreen formulations.
