Abstract

Indonesia encounters many significant challenges in organic waste management, with 37.87% of the total 38.7 million tonnes of national waste (in 2024) unmanaged. Organic waste, such as fruit peels, which are often dumped into landfill, contributes to greenhouse gas emissions and environmental pollution. Ecoenzyme, a fermentation product of organic waste (1:3:10 ratio of sugar, substrate, water), is emerging as an innovative solution for waste conversion into value-added products. Besides reducing waste volume, ecoenzymes produce ozone (O₃) that suppresses the greenhouse effect, antimicrobial acetic acid, and natural cleaning compounds. Fruit peels such as orange, banana, papaya, watermelon and pineapple are potential substrates due to their cellulose and pectin content, but the characteristics of ecoenzyme depend on the interaction of chemical (pH, Total Acid Titration/TTA) and biological (Lactic Acid Bacteria/BAL, yeast) parameters. Previous studies focused on ecoenzymes based on one type of fruit peel, while the potential of combinations of various fruit peels has not been explored holistically. This study aims to analyse the characteristics of fruit peel combination ecoenzymes through evaluation of chemical (pH, TTA) and microbiological (LAB population, yeast) parameters. The results are expected to provide scientific guidance for the production of high-quality ecoenzymes while supporting sustainable organic waste reduction strategies.

Abstract

The primary natural sources of ascorbic acid or vitamin C are fruits and vegetables, withtomatoes being one of the most readily available and accessible examples. The biosynthesisof ascorbic acid through the L-galactose pathway plays a key role in regulating vitamin C production in tomatoes. microRNAs (miRNAs) are among the various regulators that interact with mRNA involved in this process. Investigating how miRNA regulates mRNA could provide crucial information for developing genetic engineering techniques to boost vitamin C production. The main purpose of this research is to identify potential miRNA regulators ofGME using in silico approach. The research findings demonstrated that ascorbic acid biosynthesis in tomato involves 19 gene IDs. It also discovered that GME interacts with multiple miRNAs in tomatoes, specifically sly-miR-159b, sly-miR-159a, sly-miR-167, sly-miR-319c, sly-miR-319b and sly-miR-319a. Among these miRNAs, sly-miR-159a displays higher expression, which allows it to exert a suppressive effect on GME activity (negative regulator), leading to a decrease in vitamin C production. Decreasing the expression of this miRNA provides a potential molecular approach for enhancing the nutritional quality of tomato cultivars in response to the rising demand for functional foods.

Abstract

Coffee is one of the strategic plantation commodities that has high economic value and an important role in the national economy. Among the various types of coffee cultivated in Indonesia, Coffea liberica has great development potential, especially in areas such as Jambi Province. However, conventional propagation of Liberica coffee plants through seeds orcuttings still faces obstacles, such as low success rates and slow growth rates. Therefore, tissue culture techniques are an alternative solution to produce Liberika coffee seedlings in bulk, quickly, and uniformly. This study aims to optimize the effect of growth regulator (ZPT) concentration interaction of auxin (2,4-D) and cytokinin (BAP) on liberica coffee callusformation in vitro. Experiments were conducted at the Plant Biotechnology Laboratory, Jambi University, using a factorial completely randomized design (CRD) with two factors. The first factor is the concentration of 2,4-D which consists of two levels, namely 1 ppm (d1) and 2 ppm (d2). The second factor is the concentration of BAP which consists of five levels, namely 1 ppm (b1), 2 ppm (b2), 3 ppm (b3), 4 ppm (b4), and 5 ppm (b5). Parameters observed included color, structure, size, and callus weight after 12 weeks of culture. The results showed that the interaction between 2,4-D and BAP significantly affected all observation parameters. Callus with the highest size (2.66 cm) and weight (2.90 g) were obtained in the combination of 1 ppm 2,4-D + 4 ppm BAP and 2 ppm 2,4-D + 1 ppm BAP respectively. The callus was yellowishwhite to green and had a crumbly or compact structure, depending on the ZPT combination. In conclusion, a balanced combination of ZPT concentrations greatly determines the success of Liberika coffee callus proliferation, and the results of this study provide an essential basis for the development of efficient coffee tissue culture.

Abstract

Air pollution is an unresolved environmental problem to date. Traffic density will have a direct impact on the increase of various types of exhaust emissions, one of which is sulfur dioxide (SO2). Efforts that can be made to prevent further air pollution is to monitor air quality with biomonitoring utilizing lichen as a bioindicator. This study aims to identify the type of lichen species used as bioindicators in Angsana (Pterocarpus indicus Willd.) tree stands, to analyze the correlation of traffic density with sulfur dioxide (SO2) levels in lichen thallus, to analyze the correlation of traffic density with chlorophyll levels in lichen thallus, and to analyze the correlation of sulfur dioxide (SO2) levels with chlorophyll levels in lichen thallus in Medan Industrial Area II. This research is descriptive quantitative with road sampling method on Angsana tree stands in the research location. The results showed that Lichen Lepraria incana and Drinaria picta were obtained as bioindicators in both research locations. The correlation of traffic density with sulfur dioxide levels in lichen thallus showed a very strong positive correlation between traffic density and SO₂ levels with a Pearson correlation value of 0.985 and a significance value (p-value) of 0.015. Since the p-value < 0.05, this relationship is statistically significant. The correlation of traffic density with chlorophyll levels in lichen thallus showed a strong negative correlation and was also statistically significant (p-value < 0.05) with a Pearson Correlation value of -0.958 with a significance value of 0.042. Correlation of sulfur dioxide (SO2) levels with chlorophyll levels in lichen thallus showed a strong negative correlation, but not statistically significant because the p-value> 0.05 with a Pearson Correlation value of -0.943 with a p-value of 0.057.

Abstract

Industrial areas are centers of economic activity that contribute significantly to air pollution, particularly Nitrogen Dioxide (NO₂). This research aimed to explore the relationship between traffic density, NO₂ levels, and chlorophyll content in lichen thalli on Angsana trees (Pterocarpus indicus) in Medan Industrial Area 2. This quantitative descriptive study was conducted over three months, with lichen samples collected using purposive sampling method at two locations with different traffic densities. Data collection included measurements of traffic density, environmental parameters, lichen identification, NO₂ level analysis, and chlorophyll content measurement. The results showed a very strong positive correlation between traffic density and NO₂ levels in lichen thalli, and a strong negative correlation between traffic density and total chlorophyll content. A significant negative correlation was also found between NO₂ levels and total chlorophyll content in lichen thalli. Six lichen species from five families with two different thallus types were identified on Angsana trees, showing variations in coverage area and physiological responses to pollution levels. This study concludes that lichens are effective bioindicators for detecting NO₂ pollution in industrial areas with varying traffic densities.

Abstract

Cacao (Theobroma cacao L.) is a widely cultivated plantation commodity. However, its production has declined, with one of the contributing factors being old plants, so rejuvenation must be carried out using high-quality plant seedlings. Good-quality seedlings are obtained through the addition of nutrients during the nursery phase using organic and inorganic fertilizers. This study aims to determine the interaction between Asystasia compost and NPK on seedling growth and to obtain the best dosage of Asystasia compost and NPK on the growth of cacao (Theobroma cacao L.) seedlings. This research was conducted using a Completely Randomized Design (CRD) with a factorial pattern consisting of two factors. The first factor was the dose of NPK fertilizer (P), which consisted of three levels: p0 = 0 g/seedling, p1 = 7 g/seedling, and p2 = 14 g/seedling. The second factor was the dose of Asystasia compost (A), which also consisted of three levels: a0 = 83 g/seedling, a1 = 166 g/seedling, and a2 = 249 g/seedling. There were nine treatment combinations, each repeated three times. In this experiment, cacao seedlings were planted in polybags. The data obtained were analyzed using analysis of variance (ANOVA) to determine the effects, followed by the DNMRT test. The observed variables were seedling height, stem diameter, number of leaves, total leaf area, shoot dry weight, and root dry weight. The results showed that there was an interaction between the application of Asystasia compost and NPK on the variables of seedling height, total leaf area, and shoot dry weight. The application of 166 g/seedling of Asystasia compost and 7 g/seedling of NPK showed the best growth of cacao seedlings in polybags.

Abstract

The population structure of plants is a critical area of study in ecology, essential for understanding the dynamics of plant assemblages. Sandoricum koetjape (Burm.f.) Merr, commonly known as kecapi, is a plant species found along the banks of the Barito River in Sungai Gampa Village. This study aims to describe the population structure of kecapi (Sandoricum koetjape (Burm.f.) Merr)   in this riparian area. The research employed the cruise method within an area spanning 3 km in length and 50 meters in width from the riverbank, with population data based on the classification by Odum (1993). The results showed that the population structure consists of 98.68 individuals/km² (pre-reproductive), 171.05 individuals/km² (reproductive), and 26.31 individuals/km² (post-reproductive), forming an urn-shaped pyramid indicative of a disturbed population, however, the kecapi population is considered stable and not in a critical condition, as more than 25 mature individuals were found per square kilometer.
