Abstract

Sungkai (Peronema canescens Jack.) is a plant native to Indonesia that is traditionally used for dehumidifiers, treating malaria and increasing endurance. This study aims to isolate the compounds in the ethyl acetate extract of sungkai leaves and test the immunomodulatory activity of these compounds. Sungkai leaves were carried out stratified maceration using n-hexane, ethyl acetate and methanol solvents, then phytochemical screening of ethyl acetate extract of sungkai leaves, followed by an isolation process using the KVC method and isolates were obtained on F3. Phytochemical screening of F3 isolates contains steroid compounds. Immunomodulatory activity tests showed that in EEADS 50 mg/Kgbb, 150 mg/Kgbb, 450 mg/Kgbb, K+ and isolates there was an increase in the number of leukocytes and % macrophage activity compared to K-. The EEADS treatment of 50 mg/Kgbb, 150 mg/Kgbb and isolates of 0.7 mg/Kgbb did not differ markedly from K- but differed markedly from the EEADS treatment of 450 mg/Kgbb and K+. At a dose of 450 mg/Kgbb there was an increase in leukocytes and the highest % macrophage activity which was almost close to K+ (Imboost 0.7 mg/Kgbb). The UV-Vis spectrum of the F3 isolate shows a maximum absorption peak at 267 nm indicating the presence of a nonconjugation double bond. The FTIR spectrum shows isolates have groups O-H (3381.13cm-1), aliphatic C-H (2939.10cm-1), C=C (1631.44cm-1), C-H (1449.42-1362.82cm-1), and C-O (1022.32cm-1). Based on the literature comparison, the pattern of the UV-Vis spectrum and FTIR of F3 isolates has similarities with the UV-Vis and FTIR spectrum of steroid group compounds, namely β-Sitosterol.

Abstract

Pemanfaatan baja lunak dalam industri sebagai alat kontruksi dan transportasi karena baja memiliki banyak manfaat antara lain kokoh, mudah digunakan dan sederhana. Namun, baja rentan terkena korosi karena berinteraksi dengan kondisi lingkungan asam, alkali , dan lingkungan agresif lainnya. Ekstrak getah merkubung (Macaranga gigantea) dipilih sebagai inhibitor korosi karena mengandung senyawa metabolit sekunder, salah satunya yaitu tanin. Tujuan dari penelitian ini untuk manganalisis pengaruh konsentrasi ekstrak terhadap laju korosi, efisiensi dalam media air gambut. Metode pengujian yaitu metode kehilangan berat, dimana laju korosi tertinggi pada suhu 333 K dengan konsentrasi 0,5 g/L adalah 0,555 g/cm^2.jam. Sedangkan nilai efisiensi sebesar 67,196 % pada suhu 333 K dengan konsentrasi 2,5 g/L. Analisis yang digunakan pada penelitian ini yaitu Analisis Scanning Electron Microscopy/ Energy Dispersive X-Ray (SEM-EDX) dan Analisis Fouriere Transformi Infra Red (FTIR).

Abstract

Ecoprint is a technique for printing colors and shapes on fabric using natural materials. Ecoprint techniques have been introduced to junior high school students because they can capture the material and teacher's instructions independently, think critically and creatively. The purpose of the ecoprint introduction activity is to provide knowledge about ecoprint and students' skills in utilizing local potential through natural materials or plants around the school. The methods used are lectures, demonstrations, practice, and evaluation. The questionnaires and direct observations on ecoprint products were used as evaluations for this activity. Students have been able to print motifs and colors from leaves and flowers on a cloth to produce ecoprint products according to their respective creativity.

Abstract

Red Palm Oil (RPO) is the result of refining from Crude Palm Oil (CPO) which still maintains a high level of phytonutrients that are beneficial for health. The benefits of RPO can be used as a nutraceutical source, because RPO acts as a provitamin A and vitamin E. The addition of Lactic Acid Bacteria (LAB) in a product functions as a probiotic with metabolite activity that can inhibit pathogenic microorganism thereby increasing the durability of a product. The addition of LAB to RPO is expected to increase the nutraceutical value by adding probiotic properties to RPO products. Microencapsulation technology can protect the bioactive content of essential oils against unwanted chemical interactions with other components and provide increased stability during processing. This research is expected to be able to provide information about the potential raw material of fermented RPO as a nutraceutical source by showing the profile of RPO before and after the fermentation process, chemical and physical properties of the microencapsulant. The microencapsulation technique used is the extrusion method. Fermentation of the bioactive compound ingredients in RPO using L. casei has a significant effect. RPO after fermentation using L. casei (Red-PalmZym) produces major compounds in the form of 9-Octadecenoic acid, methyl ester, (E)- Fermentation of RPO with L. casei increases the components of chemical compounds contained therein. The stability of the RPO microencapsulated before fermentation provided an effective protection against oxidative damage to the oil and proved that the microencapsulation process can reduce the level of damage to the oil.

Abstract

Pilis, a traditional product containing various herbal ingredients, is currently less desir-able due to its impractical and unfashionable method of application. Pilis is used to treat dizziness, pain, eye fatigue, encephalitis in children, fever, and to aid recovery for mothers after childbirth. However, pilis also carries risks related to uncontrolled dosage and contamination, particularly from chemical or heavy metal pollutants, which may cause toxic reactions. To mitigate these risks, pilis should be used in recommended doses and produced under clean and safe conditions. This research aimed to provide the innovation of patches as an alternative treatment to increase attractiveness and control the active substances released and delivered for a long time. Transdermal patches are made from a combination of turmeric and black seed containing flavonoid active metabolite compounds, namely curcumin, carotenoids, quercetin, kaempferol, and apigenin. The combination has a synergistic effect that can increase total flavonoid levels and the therapeutic effect of pilis. The method used in this research was litera-ture review and data analysis. The results showed the effect of transdermal patch pilis from the combined extracts added to the formula in vitro and in vivo using animal tests. In conclusion, transdermal patch pilis has prospects as a topical treatment based on the combination of an active delivery system with a patch and metered dose system.

Abstract

Urinary tract infection (UTI) is one of the most common types of infection caused by the growth of microorganisms in the human urinary tract. Nitrite can be detected using spectroscopy, electrochemistry, chemiluminescence, chromatography, capillary electrophoresis, and flow injection analysis methods. However, this method takes quite a long time. So, this method is not suitable for rapid screening because it requires time for bacterial incubation and adequate sample preparation. So, there is a need for a fast-screening method that can diagnose UTIs through a nitrite colorimetric sensor. The colorimetric method is based on nanoparticles, which are relatively cheap and can provide visual and rapid detection. Nitrite is an indicator in diagnosing UTI. This research aims to determine the synthesis of Ag nanoparticles using avocado leaf bio-reductors (Persea americana Mill.) and chitosan as a stabilizer, which can be used as a colorimetric nitrite detector to minimize the use of dangerous and environmentally unfriendly inorganic materials. Characterization and analysis in this research used a UV-Vis spectrophotometer, FT-IR (Fourier Transform Infra-Red), and PSA (Particle Size Analyzer). The Ag nanoparticle synthesis process was carried out by varying the bioreductant volume, synthesis time, and chitosan concentration. It was found that the optimum synthesis time was 4 hours with an SPR value of 428 nm, an absorbance of 2.112 and a nanoparticle size. Apart from that, the optimum concentration of chitosan was obtained at a concentration of 2.5% with an SPR of 435 nm and an absorbance of 1.341 with a nanoparticle size. The results obtained from AgNPs/chitosan as a colorimetric nitrite detector showed a color change to purple with an LOD value of 0.1303 µM and an LOQ of 0.4345 µM.
