Abstract

Leukemia, characterized by abnormal leukocyte proliferation, ranks ninth in Indonesia as the most common cancer. While treatments such as chemotherapy and radiation effectively target cancer cells, they also risk damaging healthy blood cells. This has spurred interest in exploring low-toxicity herbal compounds as potential therapies, with mangosteen peel emerging as a widely researched option. Nanotechnology, which has the potential to enhance the bioavailability of herbal compounds, is also a focus of extensive research. This study objective was to assess the impact of Mangosteen Peel Nanocrystal (MPN) on HL-60 leukemia cells by analyzing various parameters, including cytotoxicity, reactive oxygen species (ROS) levels, senescence, and gene expression changes. MPN was prepared with high-speed milling and characterized using particle size analyzers, microscopy, and stability assessments. HL-60 cells were cultured and subjected to MPN treatment. Cytotoxicity was evaluated using WST-8 assays, ROS levels were assessed using flow cytometry, and senescence analyses using Senescence-Associated b-Galactosidase Staining. AKT and FLT-1 gene expression were determined via qRT-PCR. MPN has been successfully characterized as a nanoparticle based on size, stability, and morphology. MPN has an impact on leukemia cells by increasing cytotoxicity, decreasing ROS levels, inducing senescence, and modulating AKT and FLT-1 gene expressions. The findings suggest potential implications for MPN in targeting leukemia cells. The study sheds light on the promising effects of MPN in leukemia cell models, indicating its potential applications in targeting cancer cells, inducing senescence, decreasing ROS levels, and modulating gene expressions related to cell survival and proliferation.

Abstract

Background: Bagendit Lake is a tourist lake located in Garut (West Java) and has experienced a decline in water quality. This research was conducted in settlements around Bagendit Lake with the aim of studying human activities and the level of concern for the existence of Bagendit Lake. Method: Mix method (Quantitative and Qualitative) was used in this study to collect data about the activities, knowledge education and environmental ethics of the community. The data collection technique was carried out by purposive sampling involving 40 respondents aged between 18-60 years. Data were obtained by conducting field observations, interviews, questionnaires and document recording. Findings: The results showed that the community received environmental knowledge education from schools (54%) and parents (46%). Surprisingly, as many as 93% of respondents stated that they played an active role in preserving the Bagendit Lake. However, various   activities (such as tourism, fisheries, agriculture and settlements) have resulted in environmental damage to Bagendit Lake. It can be concluded that the level of knowledge and public awareness about the impact of activities on the environment has not been maximized. It is necessary to support the local government's role in implementing environmental improvement and conservation.

Abstract

Situ Bagendit merupakan danau yang dimanfaatkan sebagai objek wisata alam sekaligus kawasan lindung. Revitalisasi kawasan wisata ini berpotensi memengaruhi komunitas tumbuhan air yang berperan penting dalam menjaga stabilitas ekosistem dan berfungsi sebagai indikator pencemaran air. Penelitian ini bertujuan untuk mengevaluasi kualitas air dan indeks pencemaran menggunakan indikator tumbuhan air pasca-revitalisasi. Data dikumpulkan melalui metode purposive sampling pada lima stasiun yang mewakili berbagai tingkat aktivitas manusia. Parameter yang dikaji meliputi data biologi (komposisi tumbuhan air), serta parameter fisika dan kimia perairan. Analisis keanekaragaman tumbuhan dilakukan menggunakan Indeks Dominansi (C), Indeks Keanekaragaman Shannon-Wiener (H’), dan Indeks Kemerataan (E). Ditemukan 10 jenis tumbuhan air, dengan empat spesies dominan yang berfungsi sebagai bioindikator pencemaran, yaitu Eichhornia crassipes (Eceng Gondok), Salvinia molesta (Kiambang), Nelumbo nucifera (Teratai), dan Ceratophyllum demersum (Hornwort). Nilai rata-rata keanekaragaman tumbuhan berada pada kategori sedang (H’ = 1,11), dengan tingkat kemerataan komunitas juga sedang (E = 0,481). Berdasarkan parameter nitrogen total, kecerahan, kadar klorofil-a, serta jenis tumbuhan air yang ditemukan, status trofik Danau Situ Bagendit dikategorikan sebagai eutrofik hingga hipertrofik. Hasil ini menunjukkan bahwa revitalisasi kawasan dapat berdampak terhadap kondisi ekologis perairan yang perlu dimonitor secara berkelanjutan.

Abstract

This study aims to optimize the production of cellulase enzyme by the cellulolytic fungus Aspergillus niger using rice husk powder (Oryza sativa Linn.) as substrate. Cellulase enzymes have important roles in various industrial applications, including the bioconversion of lignocellulosic waste into high-value products such as bioethanol, pulp, paper, and animal feed. The utilization of rice husk as a substrate offers economic and environmental advantages due to its abundant availability, low cost, and ability to reduce the volume of agricultural waste. The research method used a quantitative experimental approach to evaluate the effect of fermentation parameters, such as pH, temperature, and incubation time, on enzyme production. A. niger isolates were developed on carboxymethylcellulose (CMC) media to ascertain their cellulolytic capacity, with measurements of biomass, pH, temperature, and enzyme activity. The results showed that the biomass of A. niger increased from hour 0 to hour 96 at pH 4.5 to 5.5, and temperature 29.5°C to 30.5°C. The optimum condition for enzyme production was found at pH 4.5 and temperature 30.5°C, with the highest enzyme activity reaching 0.736 U/mL. These findings suggest that optimization of cellulase enzyme production from rice husk not only improves enzyme production efficiency, but also contributes to more sustainable waste management.

Abstract

Corncob is an agricultural waste rich in cellulose, making it a promising alternative substrate for cellulase enzyme production, which is widely used in various industrial applications such as bioenergy, food, and textile industries. Aspergillus niger is a well-known cellulolytic fungus capable of efficiently producing cellulase enzymes. This study aimed to optimize cellulase production by A. niger using corncob powder (Zea mays) as a substrate through submerged fermentation (SmF), with variations in temperature (29.5°C and 30.5°C) and pH (4.5 and 5.5). The cellulolytic activity of A. niger was tested on CMC agar medium. Cellulase activity was analyzed based on the concentration of reducing sugars using the DNS method. The highest enzymatic activity was recorded at 1.125 IU/mL with a biomass yield of 0.754 mg/mL at 30.5°C and pH 4.5. These findings suggest that optimizing environmental conditions and utilizing corncob waste as a carbon source can enhance cellulase production by A. niger, offering a sustainable and cost-effective approach for enzyme-based industries.

Abstract

Ecoenzymes are fermentation products from organic waste in the form of vegetables or fruit. Many people produce organic waste in households every day, including residents in Cilingga village, Purwakarta Regency. The aim of this community service activity (PkM) is to provide education in waste/waste management as additional information. Apart from that, it also provides knowledge and awareness of community groups in making ecoenzymes as a multi-functional product, which can overcome the problem of waste or organic waste, especially in households. The service method used is Participation Action Research (PAR) through certain stages. This PkM activity is carried out in several stages, namely discussion, socialization of activities and providing education through lectures and discussions, direct practice and filling out questionnaires. The results of this training in making ecoenzymes can help the community in maintaining environmental cleanliness, managing organic waste, both agricultural and livestock waste, as well as household waste. With this training, villagers can utilize their own organic waste into ecoenzymes. Apart from reducing organic waste entering the environment, this training can also create additional sources of income and increase awareness of the importance of maintaining environmental sustainability.

Abstract

Physalis angulata and Moringa oleifera have long been the key ingredients of traditional medicine. This study aimed to obtain the metabolite profiles of the ethanolic leaf extracts of P. angulata (ELP) and M. oleifera (ELM), evaluate their antioxidant activity, and assess their toxicity against normal and cancer cells. The leaves were sourced from Balittro, West Java. The extraction used 70% ethanol and continued for 3 days. The metabolites were identified using Gas Chromatography-Mass Spectrometry (GC-MS), antioxidant activity was ascertained via the DPPH assay, and cytotoxicity was evaluated employing the PrestoBlue assay. GC-MS identified 23 compounds in ELP and 15 in ELM. The DPPH assay showed that ELM, ELP, or their combination exhibited marked antioxidant activity, with inhibition ranging from 50% to 90%. The toxicity assay against MCF-7 cancer cells demonstrated that ELP at 1,500 µg/mL and ELM at 1,200 µg/mL induced cytotoxicity. The ELP + ELM formulation exhibited stronger cytotoxic effects than the positive control. In contrast, ELM or ELP did not induce toxicity in normal CV-1 cells and, stimulated viability com-pared to the control. Thus, the phytochemical contents of ELM and ELP exhibited enhanced antioxidant activity, in-duced toxicity in cancer cells, and were safe for normal cells.
