Abstract

Celery plants (Apium Graveolens L) and bay leaves (Syzygium polyanthum) have been used as alternative medicine to treat Hyperuricemia. This study aimed to determine the effectiveness of administration of extracts from celery plants and bay leafs to decrease uric acid levels in blood. This research used a post-test control group only design. A total of 24 male mice (randomly divided into 4 groups; P0, P1, P2 and P3). P0 was the control group (induced with caffeine at a dose of 0.5 mg/kgBW). P1 was induced with caffeine 0.5 mg/kgBW+celery extract 35 mg/kgBW, P2 was induced by caffeine 0.5 mg/kgBW+bay leaf extract 35 mg/kgBW and P3 was induced by caffeine + a combination of celery plant extract and bay leaves 35mg/kgBW. Uric acid levels were measured using an easy touch GCU meter device. The results showed that average of uric acid level for P0, P1, P2 and P4 were 7.1mg/dl; 4.9 mg/dl; 4 mg/dl; and 5.2 mg/dl, respectively. The most significant antihyperuricemia activity was demonstrated by administering 35 mg/kgBW of bay leaf extract. The One Way ANOVA analysis described that the administration of extract ethanol generated significant effects (p-value <0.05). Based on post hoc LSD analysis, it was found that the administration of ethanol extract from bay leaves showed significant differences compared to combination (celery + bay leaves) in lowering uric acid levels. Therefore, it was concluded extract from celery and bay leaves can be used to lower the level of uric acid

Abstract

Pencemaran air tanah oleh logam berat seperti besi (Fe) merupakan permasalahan lingkungan yang signifikan karena dapat membahayakan kesehatan manusia. Penelitian ini bertujuan untuk menentukan jenis dan konsentrasi optimal aktivator kimia pada karbon aktif berbasis biji matoa (Pometia pinnata) dalam proses adsorpsi ion Fe(III) dari larutan. Karbonisasi biji matoa dilakukan pada suhu 400 °C, kemudian diaktivasi secara kimia menggunakan H₂SO₄, HCl, dan NaOH, serta diuji efektivitas adsorpsinya menggunakan Atomic Absorption Spectroscopy (AAS). Hasil menunjukkan bahwa aktivator H₂SO₄ memberikan performa terbaik dengan konsentrasi optimum sebesar 0,75 M, menurunkan konsentrasi Fe dari 9,498 mg/L menjadi 0,161 mg/L dalam waktu 30 menit, dengan efisiensi mencapai 98,9%. Efektivitas maksimum juga tercapai pada dosis karbon sebesar 0,5 gram, yang menandai kondisi jenuh adsorpsi. Dibandingkan dengan adsorben berbasis biomassa lain seperti kulit pisang dan tongkol jagung, karbon aktif biji matoa menunjukkan kinerja yang lebih unggul, terutama dari segi waktu kontak dan efisiensi penurunan logam. Novelty dari penelitian ini terletak pada eksplorasi pemanfaatan biji matoa yang belum banyak dikaji sebelumnya sebagai bahan baku karbon aktif yang efektif dan ramah lingkungan untuk aplikasi pengolahan air tercemar logam berat dalam skala industri.

Abstract

Peat water is surface water that is generally found in peatland areas and is mostly found in lowlands. Peat water has a low pH (3-5), is brownish-red in color, and contains many organic and inorganic substances. The more intense color of peat water indicates a higher content of chemical compounds. High levels of Fe metal in peat water can disrupt the peat swamp ecosystem itself, such as disrupting the activity of decomposer microorganisms, disrupting plant growth, and causing toxicity to humans and other living things if they consume it. This makes it not meet the requirements of household water and sanitation that is suitable for consumption. This study aims to determine the effect of the use of CuO/Zeolite catalysts on the degradation of peat water by ozonolysis method on Fe levels. After the degradation process at optimum conditions, the Fe level became 0.19 mg/L and was already at the safe limit of the quality standard used. Based on these data, the decrease in Fe metal concentration as well as BOD, COD, Nitrate, Nitrite, and TSS values in peat water by ozonolysis is more effective with the addition of CuO/Zeolite catalysts at optimum conditions.

Abstract

The soil microbiome is a complex community of microorganisms that plays an important role in the life cycle of plants, including the seed germination phase. The soil microbial community contributes to plant health and is a highly diverse complex. The soil microbial community influences plant growth in various ways, such as enhancing nutrient uptake, increasing root exudate secretion, and improving plant defense against pathogens.  Additionally, the interaction between plants and the soil microbiome is also very important. This primarily occurs in the rhizosphere, the small portion of soil where plant roots influence the microbiome through the secretion of exudates containing sugars, vitamins, organic acids, hormones, amino acids, and fatty acids. This article aims to examine the soil microbiome that plays a role in influencing seed germination as a supporting factor for sustainable agriculture. This type of research uses a literature review method. Information collection was conducted through literature studies by analyzing data from various sources over the past 10 years. The research findings indicate that microbiomes such as Azotobacter sp., Lactobacillus sp., Trichoderma sp., Bacillus subtilis, Gliocladium sp., and Beauveria bassiana can have an impact on plant germination. From the literature review conducted, it can be concluded that germination is a crucial initial stage in the life cycle of seed-bearing plants.

Abstract

The rising levels of heavy metal pollution in water bodies present major environmental and public health issues. Conventional methods for remediation often come with high costs and produce secondary waste, which can pose additional environmental risks. As an alternative, chitosan—a natural, biopolymer derived from chitin—has gained attention as a promising biosorbent for heavy metal removal. Its advantages include biocompatibility, biodegradability, and a strong ability to bind metal ions effectively. This review explores chitosan’s capacity to adsorb various heavy metals and examines its practical applications in biosorption technology. Key factors that impact its adsorption efficiency, such as solution pH, metal concentration, and contact time, are discussed. Additionally, structural modifications to enhance chitosan’s performance, including cross-linking and nanoparticle incorporation, are analyzed to highlight improvements in adsorption efficiency. By assessing these elements, this review aims to offer a comprehensive perspective on the role of chitosan in environmental management, particularly for treating heavy metal contamination in wastewater. The findings underscore chitosan's potential as a sustainable solution in pollution control, emphasizing its advantages over traditional methods and its capacity to contribute to cleaner water resources.
