In 2024, the global population is projected to reach eight and a half billion. The food industry bears a significant responsibility to provide a sufficient quantity of healthy food for this vast population. However, food production also has the potential to impact the environment. It generates waste and requires energy to produce. Furthermore, food can also have unintended consequences on human health.

Forest biomass plays an important role in biogeochemical cycles, especially in the carbon cycle. Of all forest carbon, around 50% is stored in forest vegetation. Biomass is a material that can be obtained either directly or indirectly and used as energy. This research aims to determine the biomass and carbon of trees in the forest area of Lampageu Ujong Pancu Village, Aceh Besar Regency using the direct survey method. There are three observation plots, each plot measuring 10 m × 10 m in the forest area of Lampageu Ujong Pancu Village, Aceh Besar Regency. The research results show that the biomass stored in the forest area of Lampageu Ujong Pancu Village, Aceh Besar Regency is 1,688, including the estimated biomass at station 1, 0.527, station 2, 0.785, station 3, 0.376. Meanwhile, the highest biomass and carbon stock estimates were at station 1 with species Silver nervosa total biomass 0.089 and total carbon 0.004. Station 2 with species Cleistantus myriantus total biomass 0.221 and total carbon 0.010. Station 3 with species Eurycoma longiefra total biomass 0.054 and total carbon 0.002. The total tree carbon in the forest area of Lampageu Ujong Pancu Village, Aceh Besar Regency is 0.077.

Lampageu Ujong Pancu Village Forest Area in Aceh Besar Regency is a habitat rich in biodiversity, including species from the Poaceae family which play an important role in the local ecosystem. The aim of the research is to identify and analyze the distribution of seven grass species, namely basket grass (Oplismerus hirtellus), white grass (Leersia virginica Wild), bebesan (Oplimenus burmanni), grass gerinting (Cynodon dactylon), bone grass (Eleusine indica) and kiyuyu grass (Panicum brevifolium L.). This research was carried out using a descriptive method with observational techniques, namely observing directly in the field to collect data. The research results showed that the seven types of grass were basket grass (Oplismerus hirtellus), white grass (Leersia virginica Wild), bebesan (Oplimenus burmanni), grass gerinting (Cynodon dactylon), bone grass (Eleusine indica), blady grass (Imperata cylindrica) and kiyuyu grass (Panicum brevifolium L.). has good adaptation to environmental conditions in the Lampageu Ujong Pancu Village Forest area. The descriptive observasional is effective in identifying and measuring the population and distribution of Poaceae vegetation in the region. This research provides a better understanding of the composition and ecology of Poaceae vegetation, which can be used for future forest conservation and management, as well as the environmental factors that influence it, which can become the basis for more sustainable conservation and environmental management efforts in the area .

Diversity can occur due to differences in color, size, shape, quantity, texture and appearance. Diversity is a description of the condition of the ecosystem in a place. Lampageu Village, which is in Ujong Pancu, Aceh Besar district, is home to various types of plants, both upper and lower plants, which have not been properly recorded. The aim of this research is to identify the diversity of seed plants in this place, as well as identify what types of seed plants only in Lampageu Village in Ujong Pancu, Aceh Besar district. The method used in this research is an exploratory survey and data collection techniques using exploratory techniques. Research data was analyzed using the diversity index formula with the Shannon Wiener formula. The results of research in the Lampague Ujung Pancu Village Forest Area found that there were 3 divisions of seed plants, namely, the Magnoliophyta division with a total of 36 species, the Tracheophyta division with a total of 16 species and the Spermatophyta division with a total of 2 species. The overall plant diversity index value is H'¬=3.89, this value is included in the high category

Dengue fever (DHF) is caused by the dengue virus transmitted through the mosquito vector Aedes aegypti, which is commonly found in tropical areas, including Indonesia. The use of chemical larvicides to eradicate mosquito larvae has resulted in resistant populations, which are toxic to humans and the environment. Arabica coffee leaves (Coffea arabica) contain chemical compounds of alkaloids, saponins, flavonoids, terpenoids, polyphenols that have an important role in killing Aedes aegypti larvae. This study used a completely randomized design (CRD) with each concentration tested in stages, namely 12.5%, 25%, and 50%, with the maceration method using 96% ethanol solvent. This study aims to determine the biolarvicidal potential of ethanol extract of Arabica coffee leaf plants with granule preparations against Aedes aegypti larvae in LT 50 and LT 95 in probit regression analysis and linear regression using the SPSS application. In this study there were three treatment groups, each group had 3 repetitions with concentrations of 12.5%, 25% and 50% respectively. Each repetition is observed in minutes for 24 hours. The results obtained at a concentration of 25% had the highest larval death rate with a percentage of 50.6%, a concentration of 50% with a percentage of 29.3%, then at a concentration of 12.5% with a percentage of 9%.

EFFICACY TEST OF ETANOL EXTRACT OF TALLBOOD LEAVES (Nicotiana tabacum L.) AS A BIOLARVASIDA AGAINST AEDES AEGYPTI LARVAE.

DHF is an infectious disease caused by the entry of the dengue virus into the body through the bite of the Aedes aegypti mosquito that appears throughout the year. Climate change causes changes in rainfall, temperature, humidity and air direction that affect health, especially in the development of disease vectors such as the aedes mosquito. Tobacco leaves are useful as larvicides because they contain alkanoids, saponins, polyphenols, flavonoids, steroids, and quinones. The higher the concentration of tobacco leaf extract, the higher the larvicidal effect because nicotine or alkaloids function as a poison that can affect the digestive system and nervous system of larvae while other compounds can function to damage the respiratory and gastrointestinal systems. This study aims to identify the potential of ethanol extract of tobacco leaves as a biolarvicide against dengue fever. This study used a completely randomized design (CRD) with each concentration tested in stages, namely 12.5%, 25%, and 50% to obtain LC50.95 and LT50.95 Probit regression and linear regression were analyzed using the SPSS application. In this study there were three treatment groups, each group had 3 repetitions with concentrations of 12.5%, 25%, and 50% respectively. Each replicate was observed in minutes for 24 hours. The results obtained at a concentration of 50% the highest larval mortality rate with a percentage of 30.7%, 25% concentration with a percentage of 10.7%, then at a concentration of 12.5% with a percentage of 0%.

THE BIOLARVICIDAL EFFECTIVENESS OF AVOCADO SEED ETHANOL EXTRACT IN GRANULE FORM ON HIGHEST MORTALITY PERCENTAGE WITH LETHAL TIME

Hadzqia Auliani, Aurora Salsabila, Nursafitri, Isfanda — Thu, 13 Jun 2024 00:00:00 +0000

Dengue Hemorrhagic Fever (DHF) cases have increased along with climate change. This can be a threat to society, the death rate has reached 1.237 out of 143.266 cases of dengue fever in 2022. Control of larvae is important to prevent their growth into vectors. The use of chemical larvicides has been studied and shows resistance in larvae. This problem encourages us to eradicate Aedes aegypti larvae by identifying potential compounds in avocado (Persea americana Mill.) seed as one of most potential commodities in Aceh. This study is an experimental study that aims to determine the biolarvicide potential of ethanol extract in granule form against Ae. Aegypti larvae with multigrade 12.5%, 25% and 50% concentrations of extract. This study used a Completely Randomized Design that analyzed by linear regression and probit LT 50 and LT 95. The results showed the highest percentage of mortality at a concentration of 25% which resulted in 50,6% larval mortality. The estimated lethal time value at 25% concentration is LT₅₀= 311.112801 and LT₉₅= 500.379746 which means it takes ±12 hours to kill 50% of 75 larvae and ±20 hours to kill 95% of larvae.
