A natural product that contains compounds that act as anticancer can be detected by conducting a preliminary test, namely the toxicity test. One of the methods in the Toxicity test is the BSLT test method as an initial step in the search for new anticancer compounds. The toxicity value of this method has been shown to correlate with cytotoxicity. anticancer compound. and can show a correlation to a specific anticancer. Bay plants contain saponins, triterpenoids, flavonoids, polyphenols, alkaloids, tannins, and essential oils consisting of sesquiterpenes, lactones, and phenols, which can be used as an alternative to prevent dyslipidemia, antioxidants, anti-inflammatories, antidiabetics, antidiarrheals and antihypertensives. Vile shard plant. contains various kinds of secondary metabolites and chemical substances such as potassium, sodium, silicic acid, calcium, saponins, alkaloids, polyphenols and flavonoids which act as antioxidants and can inhibit the growth and development of cancer cells. The purpose of this study was to compare the toxic effects of the ethanol extract of bay leaves and keji shard leaves on Artemia Salina Leach larvae. The type of research used was quantitative. The novelty of this research is to get the thick extract using sonification so that the time is more efficient compared to just doing maceration which takes longer. The results showed that the extracts of bay leaves and keji shard leaves are very toxic so they have the potential to be anticancer, as evidenced by the LC50 values of the bay leaf and koji shard leaf extracts which were 32.35 ppm and 194 ppm. From the LC50 value, bay leaves have higher toxicity than bitter shard leaves. The results obtained in this study can be used as an illustration for further research for the export of natural plant materials that have the potential as anticancer drugs.

This research was carried out adsorption of methylene blue dye using shrimp shell (SS) biosorbent. Methylene blue dye is commonly used in the textile and paper industries. Previously, research had been carried out on the adsorption of anionic dyes by shrimp shells, then in this study a batch adsorption was carried out to absorb methylene blue cationic dyes.It is carried out in batches with several parameters to obtain the optimum conditions. Several studies were carried out such as isotherm studies, kinetics and thermodynamics to analyze how the adsorption process occurs. The adsorption process followed the Langmuir isotherm model for the two biosorbents which showed the formation of monolayers, the kinetic model followed the second-order pseudo. The thermodynamic study of shrimp shells showed that the adsorption process was non-spontaneous, endothermic, and increased randomness. FTIR analysis shows that there are electrostatic interactions, cation exchange, and hydrogen bonding. SEM-EDX analysis shows that the pore filling of the biosorbent surface by methylene blue molecules occurs.

Penggunaan obat-obatan analgetik opioid, AINS dan atau kortikosteroid untuk meredakan nyeri maupun inflamasi memiliki resiko efek samping yang cukup besar, sehingga mendorong penggunaan obat tradisional di masyarakat. Salah satu tanaman yang digunakan di provinsi NTT adalah tanaman faloak (Sterculia quadrifida R.Br). Selama ini masyarakat hanya menggunakan kulit batang faloak sebagai obat tradisional yang tentu saja bersifat destruktif terhadap tanaman tersebut, padahal daun tanaman faloak memiliki kandungan senyawa yang mirip dengan kandungan kulit batangnya. Penelitian ini bertujuan untuk membuktikan secara ilmiah khasiat daun faloak sebagai analgetik dan anti-inflamasi. Ekstraksi dilakukan dengan metode maserasi menggunakan etanol. Ekstrak daun faloak dosis 100, 200 dan 400 mg/kg bb diuji aktivitas analgetik peripheral dengan metode siegmund, dan analgetik sentralnya dengan metode tail immersion. Ekstrak juga diuji aktivitas anti-inflamasinya menggunakan metode induksi karagenan pada telapak kaki mencit. Hasil penelitian menunjukan bahwa ekstrak daun faloak dosis 400 mg/kg bb memberikan aktivitas farmakologi terbesar baik sebagai analgetik maupun anti-inflamasi yang dibandingkan terhadap kelompok control negatif (p<0.05). Khusus untuk metode siegmund dan induksi karagenan, aktivitas ekstrak dosis 400 mg/kg bb menyerupai control positif (p>0.05). Semua kelompok dosis ekstrak daun faloak memiliki aktivitas analgetic dan anti-inflamasi sehingga diharapkan dapat dijadikan alternative dalam pengobatan.

Penelitian ini bertujuan untuk mensintesis Ceria berpori yang telah menarik banyak minat dalam aplikasinya di bidang katalisis karena memiliki siklus redoks yang unik (Ce3+/Ce4+), luas permukaan yang besar, ukuran pori teratur, dan difusi yang selektif dalam pori-pori. Struktur berpori Ceria dapat disintesis melalui proses protecting etching dengan kombinasi CTAB dan PVA sebagai protecting agent. Dibandingkan dengan penelitian sebelumnya yang terbatas dan hanya dilakukan pada logam silika, metode ini memiliki beberapa keunggulanya itu kompatibilitas untuk oksida logam yang berbeda khususnya logam transisi, reaksi satu pot tanpa prosedur multi-langkah, sintesis cepat (10 menit) dalam proses etching hingga membentuk produk berpori. Hasil analisis morfologi permukaan dengan SEM menunjukkan bahwa Ceria hasil sintesis dengan menggunakan CTAB sebagai templating agent memiliki permukaan yang berpori dan bentuk yang mengarah seperti batang (rod) serta memiliki ukuran partikel yang lebih kecil dibandingkan Ceria hasil sintesis tanpa CTAB sebagai templating agent. Hal tersebut membuktikan bahwa kombinasi CTAB sebagai templating agent dan PVA sebagai protecting agent selama proses etching dapat mengopatimalkan pembentukan struktur berpori pada Ceria sehingga dapat berpotensi iuntuk aplikasi katalitiknya.
