Abstract

The use of botanical insecticides presents a promising alternative for controlling Liriomyza sp. pests, which often damage horticultural crops. This study examines the effectiveness of various botanical insecticide materials, such as extracts from neem leaves, tobacco, and other plants containing bioactive compounds like alkaloids and terpenoids. Literature reviews indicate that botanical insecticides work through mechanisms such as feeding inhibition, growth disruption, and increased pest mortality, demonstrating effectiveness comparable to synthetic insecticides. Factors such as concentration, application methods, and environmental conditions influence the efficacy of botanical insecticides. In addition to being environmentally friendly, botanical insecticides offer advantages such as rapid biodegradability and safety for non-target organisms. However, challenges such as low compound stability and the need for more frequent applications remain significant limitations. This study highlights the importance of farmer training to enhance the adoption of this eco-friendly technology in sustainable agricultural practices.

Abstract

The demand for fruits in Indonesia continues to increase along with the increase in public consumption. Melon is one of the fruits that requires intensive handling in its cultivation because it is vulnerable to environmental changes and diseases. This study aims to determine the effectiveness of adding KCL and KNO3 fertilizers on the growth and yield of two melon varieties. This study used a non-factor randomized complete block design (RCBD). There were four treatments consisting of a combination of fertilizers and melon varieties, namely P1 (KCL and new madesta varieties), P2 (KNO3 and new madesta varieties), P3 (KNO3 and glamour varieties), P4 (KCL, KNO3 and new madesta varieties), with 6 replications so that there were 24 experimental units. The results showed that P3 treatment gave the best results in stem diameter, number of leaves, early flowering age, fruit weight and fruit diameter. P2 treatment gave the highest average yield on the parameters of fruit flesh thickness and total soluble solids (PTT). P3 treatment has the potential for further research, P3 treatment can fulfill the expected criteria with the highest fruit weight of most treatments. The provision of alternative K sources did not give a real response to melon plants, thus it would be more efficient to use K sources that are more economical in the melon cultivation system carried out.

Abstract

Population growth and high consumption patterns have led to increased waste production. This encourages people to look for effective and economically valuable solutions. One potential action that can be taken is to convert organic waste into practical utilization as food for maggot (H. illucens). Maggot (H. illucens) is one of the decomposer organisms that has a fairly high nutritional content. The objective of this study was to evaluate the impact of various feed ingredients, including vegetable waste, rice husk and bran, on the growth rate of larvae (H. illucens). The study was conducted from October to November 2024 in Meurandeh, Langsa Lama, using experimental methodology with a Rancangan Acak Lengkap (RAL) with 6 treatments and 4 repetitions for 21 days. P1: 100% bran, P2: 100% vegetable waste, P3: 100% rice, P4: combination (50% bran + 50% vegetable waste), P5: combination (50% bran + 50% rice), P6: combination (50% bran + 25% vegetable waste + 25% rice. The results showed that treatment A produced the highest absolute biomass of maggots (H. illucens), with an average of 204.25 grams, while treatment B recorded the lowest absolute biomass of maggots (H. illucens), with an average of 157.25 grams. And the highest organic waste composition for maggot length growth (H. illucens) The average length recorded in treatment E was 3.88 cm, while treatment F showed the shortest average length. The Anova results show that different feeding has no significant effect (P>1.112) total weight of biomass maggot (H. illucens), this shows that one of the elements that influence maggot growth is the quality of feed that is rich in protein and normal water content so that it can allow maggot to receive nutrients optimally.

Abstract

Phytic acid is a form of phosphorus storage that can interfere with the absorption of starch and protein as an energy source from cereal grain flour. This review aims to explore the benefits of microbial fermentation processing in producing phytase enzymes to degrade phytic acid and improve the nutritional quality of grain-based fish feed. Through a comprehensive literature study approach, reviewing the mechanism of phytase production, characteristics of potential microbes, and fermentation process optimization strategies that can affect the effectiveness of enzymes in reducing phytic acid content. The results of the study showed that the microbes Bacillus subtilis, Aspergillus niger, and Lactobacillus plantarum have the potential to produce phytase. Optimization of environmental conditions in fermentation and phytase application is influenced by media composition, environmental parameters, microbial strains and fish species, becoming the key to the success of effective enzyme application. Optimal fermentation conditions range from pH 4.5-6.5 and temperature 45-55℃. Addition of phytase with a dose of 0.75-2 g/kg feed can increase growth. Phytase can increase digestibility and is effectively needed (range 500-1500 mg/kg) in farmed fish.

Abstract

The skin serves as the body's outer protection against infection and plays an important role in water and electrolyte balance. The skin is often injured which increases the risk of infection if the wound does not close immediately. This study explored the potential of concentrated extract of Sargassum plagyophyllum in healing incision wounds in mice. Mice were given a 1 cm incision wound and then given CaCl2 S. plagyophyllum extract as the treatment group, povidine iodine as the positive control group, while the negative control group was not given anything. Macroscopic results showed that the wounds in the treatment group healed on day 17, while the negative and positive groups healed on days 15 and 16. Microscopic images showed that the inflammatory phase of wound healing was seen on day five in all groups which showed a normal phase of wound healing. These results indicate that the CaCl2 extract of S. plagyophyllum has the same potency as the positive group, but it is very important to consider the right formulation so that the effectiveness can be increased and faster in wound healing in future studies.
