Dengue Hemorrhagic Fever (DHF) is transmitted by Aedes aegypti, one of controlling vectors which is larvicides. Synthetic larvicides cause several problems so that alternative natural larvicides are used. One of which is the krokot (Portulaca oleracea, L.), the content such as flavonoids, tannins, alkaloids, and saponins can be used as larvicides. This study aims to determine the larvicides activity of krokot extract on mortality of Aedes aegypti. The study was conducted using experimental quantitative research. The study was conducted by pouring the ethanol extract on 25 larvae and repeated 3 times, for 24 hours. The result of larvae mortality test at concentrations of 4%, 5% and 6%, namely 39%, 57% dan 72%. LC50 value from krokot extract on the larvae mortality, that is equal to 9.294%. Based on the study, it can be concluded that the krokot ethanol extract is able to kill 50% of the Aedes aegypti larvae population. Keywords: krokot, ethanol extract, Aedes aegypti, mortality

Senggani leaves are a plant that can be found in Indonesia, including hilly locations. The people of Marendal, Patumbak subdistrict, believe that senggani leaves may heal minor skin wounds. The goal of this study was to identify the class of secondary metabolite chemical compounds and their antibacterial efficacy against the microorganisms Propionibacterium acnes and Staphylococcus epidermidis at 5, 10, and 20% concentrations. The ethanol extract of senggani leaves contains secondary metabolite compounds with antibacterial activity. According to the antibacterial test results, a 20% ethanol extract of senggani leaves is effective against Propionibacterium with a diameter of 10.7 mm, a 10% in the medium category with a diameter of 9.27 mm, and a 5% in the medium category with a diameter of 8.8 mm. Meanwhile, the diameter of Staphylococcus epidermidis at a 20% was 8.77 mm in the medium category, 8.37 mm at 10%, and 8.6 mm at a 5% concentration.

Hyperuricemia a condition where a person has high levels of uric acid in the blood. Red betel (Piper crocatum RUIZ & PAV) is a plant empirically used to reduce uric acid levels. This study aimed to determine the effective dose of red betel plant in reducing urinary uric acid levels in male Wistar rats with hyperuricemia. Hyperuricemia condition was obtained by giving chicken liver juice 25 mL/kg orally and potassium oxonate 250 mg/kg intraperitoneally. Red betel extract (RBE) is made by maceration using 50% ethanol. Male Wistar rats were divided into five groups: negative control (CMC-Na 0.5%), Positive control (Probenecid 4, 5 mg/kg), and extract at doses 11.5, 23 and 46 mg/kg. The results showed that the RBE increased uric acid secretion through urine (uricosuric) compared to controls. The optimal dose for the uricosuric effect of the extract is 46 mg/kg, although this effect is lower than probenecid. Keywords: Red betel, uric acid, potassium oxonate, uricosuric

Tea is one of the most commonly consumed beverages around the world. The chemical compounds contained in tea have a good effect on health because they contain polyphenolic compounds, catechins. This study examined the catechin compound content of black tea and green tea from Karanganyar (A) and Malang (B). This research aims to determine the differences in catechin levels in black and green tea types in Malang, East Java, and Karanganyar, Central Java plantations. The research method used was experimental. Identification of catechin content was done using UV-Vis Spectrophotometry method. Tea is extracted by brewing, 4 grams of green tea is brewed using distilled water for 6 minutes, while 5.6 grams of black tea is brewed using distilled water for 10 minutes with the comparison used is pure catechin solution. The results obtained for green tea Karanganyar (A) had a catechin content of 3.61±0.083%, green tea Malang (B) had a level of 2.97±0.037%, black tea Karanganyar (A) had a level of 3.14±0.065%, and black tea Malang (B) had a level of 1.60±0.009%. It is concluded that the catechin content of green tea is higher than black tea, and of the two samples, the high catechin content comes from Karanganyar (A). Keywords: catechins, green tea, black tea, malang, karanganyar

Exploration the antibacterial activity of S.trifasciata Prain. is still limited, therefore this study aims to assess the antibacterial activity of extracts and ethyl acetate fractions of Sansevieria trifasciata Prain. The S.trifasciata leaves was macerated with ethanol 96%, then fractionated using the trituration method with ethyl acetate. The treatment group was divided into positive control group (PC) using ciprofloxacin, negative control (NC) using DMSO, extract, ethyl acetate fraction 5% (ET5%), 10% (ET10%), 20% (ET20%), 40% (ET40 %). Data were analyzed statistically by ANOVA and chemometrically with PCA. The inhibition zone for S.aureus bacteria in each sample is 26.69; 1.40; 23.32;2.82; 6.23; 11.11; 20.15 mm, respectively, E.coli is 26.65;0.63;22.65;3.61;7.11;11.44;21.15 mm respectively, P. aeruginosa is 27.40; 0.00; 23.23; 2.74;7.03;11.69;21.36 mm respectively. Percent inhibition of extract, ET5%, ET10%, ET20%, ET40% on S. aureus bacteria is 82.16; 5.31; 18.12; 36.39; 70.38% respectively, E.coli is 82.67; 11.13; 24.31; 40.56; 76.99% respectively, P. aeruginosa 84.85; 10.01; 25.65; 42.68; 77.98% respectively. Extract and ethyl acetate fraction have significant potential as antibacterial (p<0.05). The results of PCA chemometric analysis showed that the extract and ET40% had similar inhibition zone area to the positive control ciprofloxacin. The extract and the ethyl acetate fraction 40% are promising for development as antibacterials. Keywords: Sansevieria trifasciata Prain., chemometric, bacterial

Acne, Atopic Dermatitis, Psoriasis and Rosacea are examples of chronic inflammatory skin conditions. One characteristic of many skin disorders is the dysregulation of innate immunity in the skin. Acne, Atopic Dermatitis, Psoriasis, and Rosacea all have problems with the expression, function, or processing of the key innate immune effector molecule in the skin, cathelicidin LL-37. Cathelicidin induction can be altered to treat Acne and Atopic Dermatitis, which lessens the efficiency of the antimicrobial barrier. However, cathelicidin is overexpressed in Psoriasis and Rosacea. The most recent research on cathelicidin LL-37’s involvement in the etiology of inflammatory skin disorders will be included in this review. Since cathelicidin LL-37 may one day be employed as a therapeutic target, many cutting-edge therapy methods for the disease will be discussed.

Breast cancer is a prevalent disease that impacts public health worldwide, including Indonesia. There are various chemotherapy regimens that are currently available. One widely utilized chemotherapy regimen for breast cancer is the FEC regimen, which combines 5-fluorouracil, epirubicin, and cyclophosphamide. This study provides a study of patient profiles and survival rates among breast cancer patients undergoing FEC chemotherapy at H. Adam Malik Hospital. The study utilized a descriptive-retrospective approach with data collected from the medical records of patients who underwent FEC therapy at RSUP H. Adam Malik during January-December 2019. A total of 157 patients were administered anthracycline-based treatment, with 54 patients receiving FEC (34.39%). The majority of individuals under the FEC regimen were primarily luminal B (51.75%) and IBC (33.33%). The survival rate for individuals using the FEC chemotherapy regimen was found to be 37.98 months. Additionally, patients with risk factors associated with invasive breast cancer (IBC) exhibited a 1.20-fold increased risk of mortality compared to individuals with other forms of breast cancer. The first-line FEC chemotherapy regimen continues to be a feasible therapeutic option for subtypes of breast cancer, and there is no discernible variation in survival rate observed across these characteristics.
