Abstract

Dyslipidemia is a condition characterized by abnormal lipid levels in the blood, including total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), and triglycerides. This condition can lead to complications such as cardiovascular diseases and stroke. The purpose of this study is to explore the potential of herbal plants from the Sasak tribe, as recorded in Lontar Usada, for managing dyslipidemia. Lontar Usada documents various medicinal plants that are traditionally used by the Sasak people, making it essential to investigate their active compounds and how they influence lipid profiles. This research employs a qualitative approach, focusing on a literature review and analysis of the plants mentioned in Lontar Usada, followed by a biochemical evaluation of their active compounds and mechanisms in regulating lipid metabolism. The findings reveal that several plants listed in Lontar Usada contain bioactive compounds with potential lipid-lowering effects, supporting their traditional use in managing dyslipidemia. In conclusion, the study confirms that the plants from Lontar Usada could offer a natural alternative for dyslipidemia management, aligning with the high cultural acceptance and availability of these plants within the Sasak community.

Abstract

One of the factors that support plants to grow and develop optimally is the availability of sufficient and balanced nutrients and minerals. Providing nutrients that are unbalanced or not in accordance with plant needs will cause symptoms of nutrient deficiencies or nutrient deficiencies. The aims of this research are (1) To determine the symptoms of the morphological appearance of corn plants in the nutrient deficiency treatment, (2) To determine the most dominant morphological appearance of the corn plants in the nutrient deficiency treatment. The type of research used was an experiment using a randomized block design with three replications. The treatment given is the provision of nutrient solutions: complete, -Ca, -S, -Mg, -K, -N, -P, Fe, - Micronutrients and water. The planting media used are cocopeat, roasted husks and a simple hydroponic method (nutrient solution as a planting medium). The parameters observed were plant height, number of leaves, leaf length and leaf width. The results of early indication of nutrient deficiency can be clearly observed in the color of the plant leaves. Leaf chlorosis is a symptom of nutrient deficiency in plants characterized by leaves that are initially green then changes color to yellow or pale. Changes in leaf color are caused by damage or malfunction of chlorophyll.

Abstract

This study aims to identify the diversity of plant species used in traditional ceremonies of the Alas tribe in Babul Rahmah District, Southeast Aceh Regency, Aceh, Indonesia. The Alas tribe’s cultural practices are deeply intertwined with the use of plants in rituals such as pesijuk, tepung tawar, majun, and kendukhi khak-khak. Using a descriptive qualitative method, data were collected through field observations and semi-structured interviews with 155 informants, aged 16 to 70, selected through purposive sampling. The informants included elders, religious leaders, and community members knowledgeable about local traditions. The results identified 35 plant species from 21 families used in traditional ceremonies, with Cocos nucifera (coconut) and Areca catechu (betel nut) from the Arecaceae family being the most prominent. These plants hold symbolic significance, representing purification, life, and honor in ritual contexts. Additionally, species from the Zingiberaceae family, such as Zingiber officinale (ginger) and Curcuma longa (turmeric), are frequently used in majun ceremonies for spiritual purification and protection. The study also highlighted a decline in ethnobotanical knowledge among younger generations, with only 40% of informants aged 16–30 demonstrating extensive knowledge of the plants used in ceremonies, compared to 85% among those aged 50 and above. This decline is largely due to modernization and the lack of integration of traditional knowledge into formal education. The research underscores the importance of preserving ethnobotanical knowledge through collaboration between traditional institutions and educational bodies, emphasizing the role of tradition-based education in mitigating the loss of cultural heritage.

Abstract

Microalgae Spirulina sp. is a blue-green autotrophic organism that has a cylindrical cell structure that forms twisted filament colonies resembling spirals, and is usually used as a natural feed in aquaculture. Development has been carried out for the production of Spirulina sp. which includes culture techniques in various production scales, but the culture of Spirulina sp. cannot rely solely on the natural environment. The study aims to evaluate the effect of lighting duration on the density and growth of Spirulina sp. The lighting duration tested was 24 hours and 12 hours using the LED light, which was replicated 8 times. The density, doubling time, growth, and spirulina biomass were analyzed statistically using the T-test. The study showed that lighting duration affected (p<0,05) spirulina's density, growth, and biomass at the 48th hour of the culture period. Spirulina reached the peak of the growth at the 48th hour. The 24th-hour lighting showed a higher density of 53,615 sin per ml than the 12-hour lighting of 38.175 sin/ml. The spirulina growth of 24-hour lighting of 0,012 sin per day was higher than 12-hour lighting of 0,004 sin per day. In biomass, the 24-hour lighting resulted in 0,249+0,02 g higher than 12-hour lighting 0,143+0,07 g. However, there is no difference (p>0,05) in doubling time between 24 and 12 hours of lighting. The study suggests using 24-hour instead of 12-hour lighting to improve performance and growth.

Abstract

Bulung boni and bulung anggur are species of Caulerpa seaweeds commonly found along the coastline of Serangan Island, Bali. Although these species have been widely utilized in various ways, formal species identification of these two macroalgae in Bali had not been conducted prior to this study. This research aims to characterize the morphological structures of bulung boni and bulung anggur through detailed morphological examination. Identification keys and previous studies were used to assist in the morphological identification process. The findings revealed that bulung boni shares morphological characteristics with Caulerpa cylindracea, while bulung anggur is morphologically comparable to Caulerpa macrophysa. These results provide valuable insights into the species composition of seaweeds in the region and contribute to a better understanding of local biodiversity.

Abstract

In the mangrove ecosystem there are many gastropods which are one of the biological resources. As a habitat, Gastropods have high diversity and occupy the mangrove ecosystem. Organic detritus gets food supply through mangrove forests and makes an important contribution as the main source of food for biota living in the surrounding waters. The purpose of the study was to determine the diversity and abundance of gastropods, determine the concentration of total organic matter (BOT), analyze the relationship between the abundance of gastropods and total organic matter (BOT) in the sediment in the mangrove habitat and determine the condition of water quality at the research location of the coastal mangrove habitat of Gambesi Village. This study uses qualitative and quantitative methods. Sampling of gastropods was carried out using a block area measuring 20 x 20 m², which was carried out at low tide. The data analysis methods used were gastropod abundance, diversity index, organic matter content, simple linear regression. The results of the analysis of the highest gastropod abundance were at station 2 for the Terebralia sulcata species of 48 individuals and the lowest were at station 1 for the Nerita polita species of 3 individuals. The diversity index of station 1 is H’= 1.80 and station 2 is H’= 1.83, included in the medium diversity category. Station 1 sediment organic matter content is 34.20% in the high category and station 2 is 49.50% in the very high category. According to the simple regression test value, the correlation coefficient value ranges from around 0.8 <r ≤ 1.0 which proves that the abundance of gastropods has a large correlation with the organic matter content in the sediment.
