Abstract

In vitro culture technique is an effective method for plant propagation to overcome the limitations of conventional cultivation. This method is used to improve accumulation of plant secondary metabolites. The purpose of this study is to review the development of micropropagation and improving secondary metabolites in Stevia rebaudiana and Curcuma plants through the application of precursors and elicitors. The systematic literature review is used to analyse scientific articles or publications from 2000 to 2025 obtained from various online databases using relevant keywords. The results showed that Stevia was more studied when compared to Curcuma due to its high economic value, with significant impact on the study of improving accumulation of stevioside and rebaudioside production through several elicitor and precursors. In Curcuma, beside in vitro culture for mass propagation, the response to in vitro treatment of elicitor dan precursors were varied, but some precursors such as phenylalanine were shown to improve curcuminoid accumulation. In conclusion, tissue culture techniques and the use of elicitor and precursor for improving secondary metabolites accumulation have the potential impact to support mass propagation, production and sustainable optimization of plant bioactive compounds.

Abstract

This study aims to examine the structure of sea urchin (Echinoidea) communities in the tidal zone of Kuta Mandalika Bay. The research was conducted in August 2024 at three different stations: River Estuary (Station 1), KEK Tourism Area (Station 2), and Mangrove Ecosystem (Station 3). Data collection was carried out using purposive sampling with line transects and plots to identify species, abundance, and environmental parameters (substrate and salinity). The results identified four sea urchin species: Diadema setosum, Tripneustes gratilla, and Enchinometra mathei. Station 2 exhibited the highest diversity and abundance (H' = 2,31; 68.70% abundance), characterized by a rocky sand substrate and salinity of 30 ppt. In contrast, no sea urchins were found at Station 1, which had a muddy sand substrate and lower salinity (28 ppt). Station 3 showed moderate diversity (H' = 1.77) with 50% abundance. Environmental factors such as substrate type, salinity, and the presence of mangrove vegetation significantly influenced the distribution of sea urchins. This study highlights the critical role of habitat characteristics in shaping sea urchin community structure in the tidal zone.

Abstract

Monoclonal antibodies (mAbs) have become a key component in modern biotechnology and healthcare, playing essential roles in the treatment of diseases such as cancer, viral and bacterial infections, asthma, and in diagnostic applications. However, conventional mAb production using mammalian cell systems is costly, time-consuming, and presents scalability limitations. To address these challenges, current technological advances have led to the development of alternative platforms using plant-based expression systems. This review aims to explore the potential and progress in producing monoclonal antibodies through the Nicotiana benthamiana plant-based expression system, which offers several advantages including rapid production, cost efficiency, greater production capacity, and reduced risk of contamination. The method employed in this review is a literature study conducted through database searches (Google Scholar, PubMed, Science Direct, and others) focusing on peer-reviewed articles from 2015 to 2024. The articles were selected and then analyzed thematically was performed to extract relevant data. The results indicate that Nicotiana benthamiana can efficiently produce functional mAbs with glycosylation profiles comparable to mammalian systems. In addition, plant antibodies have also been successfully applied in various therapeutic and diagnostic studies. Further research is needed to ensure the safety and effectiveness of Nicotiana benthamiana plant-based mAb, as well as efforts to develop production scale for wider medical applications.

Abstract

The rapid urban growth in Banjarbaru City has significantly impacted the quality and quantity of green open spaces. Fragmentation of green spaces poses a major challenge in maintaining the city's ecological balance, particularly amidst high urbanization rates. This study aims to analyze the distribution and fragmentation level of green spaces across five sub-districts in Banjarbaru City using drone technology and spatial approaches. Data were collected through high-resolution aerial mapping and spatially analyzed to identify fragmentation patterns and compare them with the 2024-2043 Spatial Planning (RTRW) of Banjarbaru City. The results show that the highest fragmentation occurs in the Landasan Ulin and South Banjarbaru sub-districts, characterized by small patches and low core vegetation areas. Meanwhile, North Banjarbaru, Cempaka, and Liang Anggang sub-districts still retain extensive and connected green spaces. A comparison with the RTRW reveals a deviation between the planned and actual conditions, particularly in areas designated to be preserved as green open spaces.

Abstract

The ongoing land-use conversion in Banjarbaru City has significantly reduced agricultural areas, potentially threatening local food availability and the achievement of food security. This study aims to identify the distribution of idle land and assess its potential utilization as an alternative for agricultural development in urban areas. The methodology integrates drone imagery for mapping uncultivated land, agricultural and biophysical statistical data, and community perception surveys to evaluate readiness and constraints in managing idle land. The results show that idle lands are spread across all districts, with the highest concentration in South Banjarbaru and Landasan Ulin. These areas exhibit high potential for the development of horticultural crops and lowland rice cultivation, although technical interventions such as soil rehabilitation and improved water access are required. In conclusion, optimizing the utilization of idle land in Banjarbaru City can serve as an effective strategy to enhance local food production and strengthen area-based food security.

Abstract

Research on the heavy metal lead (Pb) is important to protect consumers from dangerous heavy metal contamination. The main objective of this research is to determine the levels of Lead (Pb) metal in the body of Tilapia Fish (Oreochromis mossambicus) obtained in Taliwang Lake. The results of this study are useful so that consumers of Tilapia fish can avoid fish that are contaminated with Pb heavy metals. Data collection for this research was carried out in Taliwang Lake. It was determined that there were 2 stations in this research, namely in the eastern and western parts of the lake. Fish were caught by using gill nets. Four fish were taken at each research station as samples. The next stage, the Tilapia fish samples were wrapped in plastic samples, which were then placed in sample boxes. The destruction of tilapia fish muscle samples was carried out in the Mataram University Analytical Laboratory and the Pb content analysis was carried out at the DLHK Environmental Laboratory West Nusa Tenggara. The Pb metal content was analyzed by using an AAS (Atomic Absorption Spectrophotometer) tool. Measurement of this heavy metal was carried out by adding concentrated HNO3 and HClO4 then heated at a temperature of 60 - 70ºC with a time span of 2-3 hours until the solution became clear. The solution sample was then measured with an AAS tool using an air-acetylene flame. The conclusion of this research was that the content of heavy metal Lead (Pb) in the tissue of Tilapia Fish (Oreochromis mossambicus) taken from Lake Taliwang waters was 0.0005 mg/kg (ppm).

Abstract

Black rice contains antioxidants that neutralize free radicals, helping prevent wrinkles and skin damage. Fragrant lemongrass produces essential oils with citronellal, geraniol, and citronellol, which have antibacterial effects. This study aims to develop and evaluate a face mask combining black rice extract and citronella essential oil to nourish, cleanse, and tighten the skin. Masks were formulated with black rice concentrations of 30%, 40%, and 50%. Evaluations included phytochemical screening, antioxidant activity (DPPH assay), organoleptic properties, pH, homogeneity, dispersibility, and physical stability. Black rice extract showed antioxidant content of 0.037 mg/L, while the mask formulations exhibited strong antioxidant activity at 2.231 mg/L. The FII mask met Indonesian National Standard (SNI) criteria for physical stability. Clinical tests from week 2 to 6 on volunteers revealed that the FIII mask improved skin firmness, reduced acne and black spots, and increased moisture. This research demonstrates that combining black rice antioxidants with citronella essential oil produces an effective natural face mask that enhances skin health.
