Abstract

Pluchea Indica L. or beluntas plant is a medicinal plant that contains several bioactive components including tannins, alkaloids, flavonoids, saponins and essential oils. The flavonoids in beluntas leaves can act as antioxidant, anticancer and antidiabetic compounds. This research aims to determine the effect of fermentation time and maceration time and to obtain the best conditions for the flavonoid levels of beluntas leaf extract. One way to obtain high amounts of beluntas leaf flavonoids is by maceration extraction with fermentation of Rhizopus sp. This research was carried out by fermenting beluntas leaf powder using Rhizopus sp at a temperature of 30°C and aerobic conditions with a time of (48; 72; 96; 120; 144) hours. After fermentation, the beluntas leaf powder will be analyzed using UV-Vis spectrophotometry. Next, the beluntas leaf powder will be extracted using the maceration method using 90% methanol solvent with a maceration time (24; 36; 48; 60; 72) hours, then filtered to separate the filtrate and sediment. The filtrate was distilled to obtain beluntas leaf extract, then the beluntas leaf extract was analyzed for flavonoid levels using the UV-Vis Spectrophotometry method. The results showed that fermentation time and maceration extraction time had an effect on the flavonoid content of beluntas leaf extract. The best flavonoid content was obtained at 1.0398% at a fermentation time of 96 hours and a maceration time of 48 hours.

Abstract

Many industries in Indonesia have switched to using coal fuel. The use of coal at PT PLTU Paiton has reached 250 tons per hour and produces 4% of waste by-products of combustion contained from bottom ash by 25% and fly ash by 75%. Fly ash waste will harm the environment and health. Fly ash contains many components, including SiO2 52%, Al2O3 31.86%, Fe2O2 4.89%, CaO 2.68%, and MgO 4.66%. This research aims to synthesize and characterize zeolite X from PT Paiton fly ash using a low-temperature synthesis method. Zeolite X synthesis in this study has 3 steps: The pretreatment process, silica synthesis process, and zeolite synthesis process. The results of silica synthesis obtained SiO2 55.54%. The resulting zeolite product has a typical peak at 2Ï´ 28.72. Zeolite x has a wavelength of 430, 570, 695,7, and 965,7, which respectively indicates Si-O-Si and Si-O-Al bonds, double ring bonds, T-O ring symmetric strain (internal), and asymmetric (internal). The results of zeolite X crystal synthesis in this study could not be formed in the variable of adding time of 3-5 hours with a variation of moles of Al2O3 0,5-1,5 moles.

Abstract

This research aims to identify the obstacles and challenges faced by class I and IV students in following the Independent Learning Curriculum at SDN 064976 Tembung, as well as finding effective strategies to improve their abilities. The research results show challenges related to limited teacher understanding, limited resources, and students' difficulty adapting. Recommended strategies include increasing teacher understanding, developing resources, and intensive mentoring for students. This research provides insight into the implementation of the Independent Curriculum in elementary schools and can be used as a basis for optimizing its implementation..

Abstract

Minyak atsiri merupakan zat berbau khas yang tekandung didalam tanaman. Minyak ini disebut juga sebagai minyak esensial dikarenakan pada suhu kamar mudah menguap. Salah satu minyak esensial yang paling berharga adalah minyak mawar. Bunga mawar sangat melimpah terdapat di Desa Kalipucang, Kecamatan Tutur, Kabupaten Pasuruan. Ketersediaan tersebut dapat dimanfaatkan untuk menambah nilai jual tanaman tersebut. Pembuatan minyak atsiri bunga mawar menggunakan rangkaian alat penyulingan yang sederhana (water distillation) meliputi panci presto, pipa besi dan bak kondensor. Penyulingan ini menggunakan sistem dimana bahan yang akan diambil minyak atsirinya berhubungan langsung dengan air mendidih. Sebanyak 1 kg bunga mawar dapat menghasilkan ekstrak sebanyak 150 ml. Pada kegiatan pengabdian ini, mahasiswa diberikan kesempetan untuk mendapatkan pengalaman belajar secara langsung dari lapangan dan unutk memberikan kontribusi dalam program pengembangan. Bentuk pengabdian kepada masyarakat sendiri adalah dengan dilakukannya pembuatan minyak atsiri dari bunga mawar di Desa Kalipucang, Kecamatan Tutur, Kabupaten Pasuruan. Produk ini juga dapat meningkatkan ekonomi masyarakat Desa Kalipucang.

Abstract

Furniture production made from mahogany wood produces sawdust that contains biomass such as cellulose, hemicellulose, and lignin. The lignin content in mahogany wood can be used as raw material for making sodium lignosulfonate surfactants. Delignification of lignin is carried out alkaline and continued with lignin isolation by acid precipitation. Pure lignin isolate is further used as a raw material for making sodium lignosulfonate surfactants using the sulfonation process. The sulfonation process is carried out by mixing lignin isolate and sodium bisulfite solution using excess NaHSO3 variation and sulfonation time. Both variables are run by adding sodium hydroxide as a catalyst and the pH condition was maintained at pH 4. The sodium lignosulfonate surfactant solution formed was then characterized using FT-IR spectrophotometer and UV-Vis spectrophotometer. The best condition was obtained at a sulfonation time of 150 minutes and NaHSO3 exceeded 75%, namely with a surfactant concentration of   4100,784 mg/L.
