Abstract

Women’s breast cancer incidence rate in Indonesia ranks number one with 12 per 100,000 cases, with luminal A as the dominant subtype. Currently, chemotherapeutic agents have limitations that lead to inefficiencies in therapy, therefore it is necessary to develop more effective and efficient chemopreventive agents. Plant secondary metabolites can provide pharmacological effects that can be used as chemoprevention agents. Secondary metabolites of D. serrata may have pharmacological effects as antioxidants and cytotoxic. This study aims to determine the antioxidant properties and cytotoxic activity of D. serrata ethanolic extract on the MCF-7 breast cancer cell line. The leaves of D. serrata were macerated, while the bark and root samples were refluxed with 96% ethanol as solvent. All extracts were evaporated with a rotary evaporator. Qualitative evaluation of the phytochemical content of leaf ethanolic extract, bark ethanolic extract, and root ethanolic extract was done using the standard tube test method. The antioxidant assay was carried out using the DPPH. The cytotoxic activity was determined in vitro using an MTT assay against the MCF-7 cell line with a series of concentrations from 12.5–400 μg/mL. Doxorubicin was the positive control treated at a 3.125–100 μg/mL concentration. The antioxidant activity showed that leaf extract had the highest antioxidant activity, followed by root and bark extract, with IC50 values of 95.66, 270.5, and 335.96 ppm, respectively. Leaf ethanolic extract and root ethanolic extract’s cytotoxic ability is considered moderate cytotoxic with IC50 values of 493.17 and 229.82 μg/mL, respectively. Amongst the ethanolic extract from the leaf, bark, and root of D. serrata, the leaf ethanolic extract has the best anti-oxidant activity and the bark ethanolic extract was the most cytotoxic one against MCF-7 cells.Keywords: Antioxidant, Cytotoxic, Dillenia serrata, MCF-7.

Abstract

Phylanthus species, including P. niruri and P. urinaria have pharmacological potential due to their rich phytochemical composition. People usually used this plant for medicinal treatments. This study aimed to compare the phytochemical and antioxidant and antibacterial activities of two Phyllanthus species. The whole of plants was extracted using maceration method with ethanol as solvent. Phytochemical content analyzed using spectrophotometer.  The reagent used for each compounds that were Folin-ciocalteu for phenolics, AlCl3 for flavonoid, dimethyl sulfoxide for chlorophyll and carotenoid. Bioactivity analysis using 1,1-diphenyl-2-picrylhydrazyl method for antioxidant activity and Kirby-Bauer method for antibacterial activity. The highest flavonoid content (12.22 mg QE/gram extract) and total chlorophyll (43.2 µg/ml extract) in P. niruri while phenolic content (80.8 mg GAE/gram extract) in P. urinaria. The carotene of both Phyllanthus were similar (11.9 µg/ml extract. The IC50 values of P. urinaria (6.16 ± 0.42 μg/ml) and P. niruri (17.72 ± 0.80 μg/ml), which indicated very strong antioxidant activity. P. urinaria leaf extract had stronger inhibition against Escherichia coli than Staphylococcus aureus (>20 mm) and P. niruri leaf extract could inhibit E. coli and S. aureus bacteria at all concentrations (11-20 mm). This study found that phenolic compounds strongly influenced the antioxidant and antibacterial abilities of Phyllanthus, while chlorophyll and carotenoids had only a slight influence. These findings open up opportunities to utilize P. niruri and P. urinaria as antioxidant and antibacterial agents.

Abstract

Cabe jawa (Piper retrofractum Vahl.) merupakan tanaman herbal yang mengandung alkaloid utama piperin. Prospek cabe jawa sebagai bahan obat belum didukung oleh ketersediaan bahan baku yang cukup, karena rendahnya produktivitas tanaman. Salah satu alternatif untuk mengatasi permasalahan tersebut adalah dengan menerapkan kultur kalus. Kalus dapat memproduksi metabolit sekunder relatif cepat dan berkelanjutan. Efektivitas produksi metabolit sekunder seperti piperin pada kalus dapat dilakukan dengan meningkatkan konsentrasi sukrosa dalam medium kultur. Penelitian ini dilakukan untuk mengetahui pengaruh konsentrasi sukrosa pada morfologi kalus, pertumbuhan kalus, dan produksi piperin pada kalus cabe jawa. Medium Murashige and Skoog (MS), dan zat pengatur tumbuh naphtalene asetic acid (NAA) dan benzyl aminopurin (BAP) 1:2 digunakan untuk menginduksi kalus dari daun cabe jawa. Kalus yang terbentuk berwarna hijau muda dan kompak. Kalus disubkultur selama 35 hari pada medium MS dengan konsentrasi sukrosa 30 g/L, 40 g/L, 50 g/L, dan 60 g/L. Setelah inkubasi warna kalus berubah dengan tekstur tetap kompak. Berat segar dan berat kering dari kalus menurun dengan bertambahnya konsentrasi sukrosa. Piperin pada kalus diekstraksi dengan etanol 96% dan diukur kadarnya dengan Kromatografi Lapis Tipis (KLT)-Densitometri. Peningkatan konsentrasi sukrosa pada medium kulur tidak berpengaruh pada kadar piperin dari kalus cabe jawa.

Abstract

Dengue Hemorrhagic Fever (DHF) remains a major public health problem in Indonesia, particularly in urban and peri-urban areas where Aedes aegypti thrives. Tomohon City has experienced a significant increase in DHF cases and, in early 2024, ranked among the top five regions with the highest Incidence Rates (IR) in Indonesia. This study aimed to assess the distribution and density of A. aegypti larvae through ovitrap-based surveillance and to evaluate residents' basic knowledge of DHF and its vectors in Kolongan Satu Village, Tomohon City. A cross-sectional study was conducted using larval surveillance and a structured questionnaire. A total of 200 ovitraps were placed both indoors and outdoors in and around 100 houses across five surveillance stations. Egg collection was carried out in two stages. Collected eggs were identified morphologically as A. aegypti. Vector density was analyzed using the Ovitrap Index (OI) and Ovitrap Density Index (ODI). Residents’ knowledge regarding DHF transmission, vector characteristics, and preventive measures was assessed descriptively. The results showed that the OI values during stage 1 were 25.5% indoors and 39% outdoors, while during stage 2, the values were 24% indoors and 35% outdoors, indicating a medium level of vector presence. The ODI increased markedly from 3.21% in stage 1 to 9.72% in stage 2, reflecting a high density of A. aegypti. Most respondents demonstrated good knowledge of DHF, its vectors, and preventive strategies, although some difficulties in understanding scientific terminology were identified and addressed through education. These findings indicate persistent A. aegypti breeding in Kolongan Satu Village and highlight the need for strengthened vector control measures and continuous community-based education to prevent future DHF outbreaks.

Abstract

Soil salinity is a significant constraint on crop productivity, particularly in marginal lands, and sustainable biological approaches are needed to mitigate its impact. Plant growth-promoting rhizobacteria (PGPR) with halotolerance represent promising candidates for enhancing plant resilience under saline stress. This study aimed to isolate halotolerant PGPR from saline-impacted soils in Pekalongan, Indonesia, and evaluate their potential to improve plant growth under salinity stress. Five bacterial isolates (WN-01 to WN-05) were successfully obtained. The isolates displayed multiple PGPR traits, including nitrogen fixation, phosphate solubilization, indole-3-acetic acid (IAA) synthesis, siderophore release, cellulase activity, 1-aminocyclopropane-1-carboxylate (ACC) deaminase activity, exopolysaccharide production, and tolerance to salinity up to 9% NaCl. Molecular identification confirmed the isolates as Bacillus subtilis (WN-01), Priestia megaterium (WN-02), Pseudomonas segetis (WN-03), Bacillus pumilus (WN-04), and Bacillus cereus (WN-05). Compatibility analysis indicated their potential to be formulated as a consortium bioinoculant. In vivo pot experiments using sweet maize (Zea mays saccharata var. Bonanza F1) under saline conditions (4 dS m-1) showed that consortium application, especially at 10⁸ CFU ml-1, significantly enhanced plant height, leaf surface area, and chlorophyll content. Moreover, the total microbial population in soil increased proportionally with inoculum density, with the highest values recorded in the 10⁸ CFU ml-1 treatment. These findings demonstrate that local halotolerant PGPR have strong potential as bioinoculants to support crop growth and soil health in saline-impacted marginal lands.

Abstract

Indonesia’s shallot production still falls short of domestic demand, necessitating imports. Expanding cultivation into marginal coastal areas such as Yogyakarta is promising but constrained by soil salinity. Silicon can help by enhancing plant resistance to such abiotic stress. This study evaluated the physiological and biochemical responses of shallot plants (Allium cepa L. Aggregatum group) to the application of calcium silicate (CaSiO3) under saline conditions. The experiment employed a completely randomized design with 2 factors: CaSiO3 (0, 2, and 4 mM) and salinity (0, 2, 4, and 8 dS m⁻¹), each with 5 replications. Physiological parameters, antioxidant activity, and yield traits were analyzed using analysis of variance (ANOVA) followed by Duncan multiple range test (DMRT) at p ≤ 0.05. CaSiO3 significantly alleviated salt stress by enhancing superoxide dismutase (SOD) activity and membrane stability, improving photosynthetic efficiency, promoting growth, and yield components. Under high salinity, 4 mM CaSiO3 reduced proline and H₂O₂ accumulation compared with untreated plants. These findings indicate that applying 4 mM CaSiO3 can enhance shallot productivity and resilience in saline coastal soils, supporting sustainable shallot self-sufficiency in Indonesia.
