Abstract

Cocoa is a strategic plantation commodity that contributes significantly to export-import activities, increasing the country's foreign exchange. However, the distribution of cocoa seeds is faced with the problem of recalcitrant seeds, which can be overcome by using natural allelopathic substances. Natural allelopathic plant extracts contain toxic compounds such as alkaloids, phenolics, and terpenoids which are effective in inhibiting germination. The purpose of this study was to determine the effect of the type of extract and the concentration of natural allelopathic substances in inhibiting the process of seed germination and growth of cocoa seedlings. This study used a factorial Completely Randomized Design (CRD). The first factor was the type of extract, namely cogongrass roots and tomato leaves. The second factor was the concentration of natural allelopathic substances, namely control, 4%, 6%, and 8%. Data were analyzed using the ANOVA (Analysis of Variance) test. If there was a significant difference between treatments, further testing was carried out using Duncan's multiple range test at the 5% level. The results of the study showed (1) the interaction between the type of extract and the concentration of natural allelopathic substances had a significant effect on the observed variables of germination power, vigor index, lethal concentration (LC50), plant growth rate, and number of leaves, with the best treatment being the cogongrass root extract at a concentration of 4%. (2) The effect of the type of natural allelopathic extract had a significant effect on the parameters of vigor index, plant growth rate, number of leaves, and stem diameter. (3) The effect of the concentration of natural allelopathic substances had no significant effect on any of the observed variables.

Abstract

Indonesia has a wealth of biodiversity in the form of various types of fungi, one of which is the black ear fungus (Auricularia polytricha) which is known to contain chemical compounds with the potential to inhibit the growth of pathogenic fungi. This study aims to determine the effect of black ear fungus extract hair tonic on the growth of Malassezia furfur and the best concentration in inhibiting the growth of M. furfur. This type of research is a quantitative study with an experimental method with a Completely Randomized Design (CRD) consisting of 6 treatments, namely: P0: hair tonic brand X, P1: hair tonic without extract, P2: hair tonic extract black ear fungus with a concentration of 10%, P3: 30%, P4: 50%, and P5: 70% with 4 repetitions. The parameters observed were the diameter of the inhibition zone indicating antifungal activity with the best concentration, as well as the hair tonic evaluation test (organoleptic test, pH test, viscosity test, and irritation test). The data obtained were analyzed using ANOVA and continued with the DNMRT test with a confidence level of 95%. The results showed that black ear fungus extract hair tonic had an effect on the growth of M. furfur. The results of the DNMRT test showed that P0 was significantly different from other treatments. Treatment P1 was also significantly different from other treatments. Hair tonic extract concentrations of 10% (P2), 30% (P3), and 50% (P4) were not significantly different. Hair tonic with the highest concentration of 70% (P5) was significantly different from other treatments and had a very strong antifungal category. The conclusion of this study is that there is antifungal activity of black ear fungus extract hair tonic on the growth of M. furfur, and the best concentration of antifungal hair tonic is 70%.

Abstract

Konyal (Passiflora suberosa L.) is a wild and invasive plant belonging to the Passifloraceae. The existence of P. suberosa as an invasive species can threaten the existence of local plants. As a scientific conservation area, the Kebun Raya Bogor (KRB) is a habitat for Konyal. One effort that can be made to minimize the threat of invasive species is through mapping. The aim of this research was to map the distribution of konyal (P. suberosa) in the scientific conservation area of Kebun Raya Bogor and measure environmental factors in the habitat of konyal (P. suberosa). The research was carried out using an exploratory method throughout the Kebun Raya Bogor area in January 2024. Documentation of komyal (P. suberosa) and measurements of environmental factors in its growing habitat were carried out during exploring activities. In addition, distribution coordinate data was recorded and used for mapping using QGIS v3.36.2 program. The research results showed that the konyal  (P. suberosa) in the KRB was spread over six areas, including II A, II C, II D, II F, III I, and  XIII A. Environmental factors at the location where P. suberosa was found in the Kebur Raya Bogor area, such as air humidity (70 – 77%), temperature (26 – 33 ˚C), and light intensity (2250 – 16200 lux). Distribution of konyal (P. suberosa) in KRB area showed high density in vak II (II A, II C, II D, and II F). The location vak II has vegetation with sparse canopy and low shade, thereby increasing the sunlight intensity compared to other areas.

Abstract

The Arecaceae family holds significant ecological and economic value and is widely distributed in tropical regions, including Indonesia. This study aimed to inventory the Arecaceae species found in the Lembah Bukit Manjai Tropical Rainforest Biodiversity Park. A descriptive exploratory method was employed using field research and purposive sampling techniques. Data collection involved direct observation, morphological documentation, and species identification based on taxonomic references. The results identified five Arecaceae species: Arenga pinnata, Calamus manan, Caryota mitis, Calamus zollingeri, and Licuala spinosa. Species distribution was influenced by abiotic environmental factors such as light intensity, temperature, humidity, and soil pH. Calamus manan was the most dominant species, while Caryota mitis was the least encountered due to its low ecological tolerance. This study underscores the importance of biodiversity conservation and the use of inventory data as a foundation for sustainable tropical ecosystem management. Furthermore,  it contributes to the development of local taxonomic databases and documentation of potentially endemic species in South Kalimantan.

Abstract

Biodiversity Park of Bukit Manjai Valley, South Kalimantan. The research employed a cruising method through direct observation and morphological documentation. Seven Araceae species were identified: Alocasia princeps, Alocasia sarawakensis, Amorphophallus borneensis, Amorphophallus paeoniifolius, Amorphophallus muelleri, Amydrium medium, and Schismatoglottis ahmadii. Each species showed distinct morphological traits and ecological adaptations to the tropical rainforest environment. Measurements of abiotic factors like temperature, humidity, light intensity, soil pH, and wind speed indicated suitable habitat conditions for Araceae. Scientifically, the study contributes valuable data to the enrichment of local taxonomic databases, serving as a reference for botanical classification and species verification in South Kalimantan. Moreover, the documentation strengthens baseline information needed for the conservation planning of endemic and potentially threatened Araceae species in the region. The results also have applied value for the development of local-content-based learning media in higher education, particularly in the Phanerogamae course.

Abstract

South Kalimantan is known for its rich biodiversity, particularly within the Tropical Rainforest Biodiversity Park of Lembah Bukit Manjai, which serves as a habitat for various tropical forest plant species. Among these is the genus Amorphophallus, notable for its ecological, economic, and conservation value. These plants typically grow in shaded and humid forest floors. This study aimed to identify and describe Amorphophallus species present in the study area. A descriptive-exploratory method was applied using purposive sampling. The study recorded three species: Amorphophallus muelleri, A. paeoniifolius, and A. borneensis. These species were found thriving under low to moderate light intensity, high soil moisture, and neutral pH. Key morphological traits such as habit, leaves, stems, and roots were documented for each species. The findings indicate that the ecological conditions of the study area strongly support the growth of Amorphophallus spp., and that these plants hold potential as local biodiversity-based learning resources.

Abstract

Rice is the most important agricultural commodity in Indonesia. As a staple food, rice contains carbohydrates, protein, and other nutrients essential for the human body. The level of rice consumption in Indonesia is relatively high, which must be balanced by increased production. One way to improve yields is through the use of high-quality seeds. However, rice seeds available on the market are often past their shelf life (aged), resulting in decreased seed viability and negatively affecting plant growth. Therefore, efforts are needed to improve the quality of aged seeds. This study aimed to examine the effect of exposure to a magnetic field with an intensity of 0.2 mT on the vegetative growth of aged rice seeds of the Inpari 32 HDB variety. The research was conducted at the Botany Laboratory of the University of Lampung and in Lumbirejo Village, Pesawaran Regency, from July to September 2024. The study used a Completely Randomized Design (CRD) with four magnetic field exposure treatments: 3 minutes 54 seconds, 7 minutes 48 seconds, 11 minutes 42 seconds, and a control group with no exposure, observations were conducted for 8 weeks or 56 days after planting and were made every two weeks. The parameters observed included leaf area, number of leaves, rice tiller height, number of tillers, fresh weight and dry weight of the shoot, and wet weight and dry weight of the root. The research results showed that exposure to a 0.2 mT magnetic field only caused an effect during the early growth phase (2 weeks after planting) in several parameters such as leaf number, plant height, and number of tillers. However, this effect did not continue in the subsequent vegetative phase. Other parameters like leaf area and biomass did not show significant differences between treatments. Thus, the magnetic field at this intensity does not provide a stable influence on the vegetative growth of rice.

Abstract

Pine forests (potential. However, their utilization by communities around forest areas is still limited, Pinus merkusii) are a forest resource with great economic, ecological, and social especially in terms of getah tapping and the use of the area as a tourist attraction. This study aims to analyze community efforts in utilizing P. merkusii in the Selo Ondo tourist area, Ngrayudan Village, Jogorogo District, Ngawi Regency, and to identify other potential uses that have not been optimized. This study employs a qualitative descriptive research method through direct observation and interviews with communities surrounding the tourist area. Data analysis is conducted using data reduction, data presentation, and data verification techniques. The results show that the utilization of pine trees by the community is still not optimal and has not led to the diversification of value-added products. Utilization is still focused on pine sap and environmental services in the form of nature tourism. Meanwhile, other parts of the pine tree, such as needles, flowers, and organic waste, have great potential to be developed as bioenergy products, handicrafts, and educational ecotourism support. Lack of knowledge, skills, and guidance are the main factors hindering the optimization of pine utilization.
