Abstract

Natural predators of mosquito larvae are known and used as biological control of the mosquito larvae of Aedes aegypti, one of them is a copepod, Mesocyclops aspericornis. The effectiveness of the biological control of Aedes aegypti larvae requires an efficient method to rear Mesocyclops aspericornis copepodite. This research aimed to determine the feasibility of various organic manures, i.e., cow dung (RKS), goat manure (RKK), and marmot manure (RKM) as aquaculture media of M. aspericornis copepodite. This experiment was conducted in the laboratory using a post-test only control group design. The group design consisted of 5 concentrations of 0%, 25%, 50%, 75%, and 100%, each with three replicates for each organic manure media. The statistical analyses showed each organic manure medium was not significantly affecting (p = 0.521) the copepod aquaculture. However, the concentration of the manure has a significant correlation with the number of copepodites raised (p = 0.001). Games-Howell test suggested the most effective manure concentration to rear M. aspericornis copepodite was 25%.

Abstract

Aedes aegypti is a mosquito species primarily known as the vector for dengue fever. The Hatching and development larval of Aedes agypti are crtical factors in mosquito control strategies and reducing dengue fever transmission. This study aims to investigate the effects of different water media on the hatching rate and development of Aedes aegypti from egg to adult stage. Three type of water from well water, treated tap water (PDAM) and staw soaked water were used in the experiment. The selection of water sources was based on their distinct physical and chemical properties, representing common environmental condition where Aedes aegypti may breed. Straw soak water was incorporated to simulate organic rich aquatic environments, often characterized by the presence of decomposing plant material. Such conditions are known provide a nutrient rich medium that facilitates mosquito egg hatching and larval development. Eggs were placed in each water type, and observations were carried out at hatching rate and larval development. The result revealed that the straw soaked water had the highest hatching rate 100% and the development time 6 days from egg to adult, well water show a hatching rate 67% with a longer development period of 7 days and no hatching and larval developmet in tap water (PDAM). This study shows that various types of water media affect the hatching success and developmental rates of Aedes aegypti. However, these effects are limited to the specific water types used in the experiment and should not be assumed to apply to all water quality conditions. Future research is recommended to explore other water quality parameters and their potential impact on the mosquito life cycle

Abstract

Empty Oil Palm Fruit Bunches (EFB) or empty bunches are organic waste produced from the processing of fresh oil palm fruit bunches into crude palm oil (CPO). EFB can be a growing medium for macroscopic fungi. This study aims to determine macroscopic fungi in EFB in the oil palm plantation of Tawiora Village, Rio Pakava District, Donggala Regency, Central Sulawesi Province. The study was conducted using exploration and identification methods based on the morphological characteristics of macroscopic fungi. Based on the study, there is one genus of macroscopic fungi in the oil palm plantation of Tawiora Village, namely: Volvariella. Volvariella has an umbrella-like shape, its hood is round egg-shaped which is then convex, the hood is brown to grayish brown, the stem is light brown, the cup is light brown with a membrane-like texture that forms a thick bowl, and the spore trail is pink.

Abstract

Lombok is one of the island in the Lesser Sunda Islands. This island has high biodiversity, one of which is orchids. Orchids are a group of epiphytic plants that are in great demand because of the beauty of their flowers. This research aims to determine the diversity of orchid species in Sengkol Village, Pujut District, Central Lombok Regency. The research was carried out using an exploration method followed by species identification based on morphological characteristics. Based on research, it was found that two species of orchids were used as ornamental plants in Sengkol Village, namely: Phalaenopsis pulcherrima (Lindl.) J.J.Sm. and Vanda coerulea Griff. ex Lindl.

Abstract

The Environmental pollution caused by industrial waste including oil spills have become a global issue that requires effective and environmentally friendly solutions. Bioremediation used by bacteria immobilized has been develop as a promising method for pollutant degradation, because it can increase the stability and activity of microorganism under various condition in the environment. This study is a systematic review to evaluate various immobilized technique including adsorption, entrapment, adsorption-embedding, cross linking and the techniques effectiveness in hydrocarbon, crude oil, and heavy metals remediation. This review collates a vast amount of existing literature on the myriad contaminants treated using immobilized bacteria. Based on the reviewed article, the immobilization techniques such as adsorption, adsorption-embedding, entrapment and cross-linking were frequently reported to enhance degradation performance, particularly in crude oil bioremediation. The techniques consistently demonstrated high effectiveness in pollutant degradation across different environmental conditions. The environmental factors, including pH, pollutant concentration and surfactant availability have an important role in the success of bioremediation. Although, this technology enhances bacterial resilience and biodegradation efficiency, the challenges such as the hight cost of immobilization materials and limitations in extreme environment application remain a problem. The optimization techniques and immobilized materials has the potential to provide a sustainable solution for pollutant bioremediation in the environment
