Chemical profiling, bioactive compounds, antioxidant, and anti-inflammatory activities of Indonesian propolis extract produced by .

Propolis produced by stingless bees contains various chemical compounds that contribute to its bioactivity. The availability of certain plants at the growth site and the propolis's geographic origin have a significant impact on its chemical composition. The objective of this study was to examine the chemical profile, yield, total flavonoid and phenolic content, and antioxidant and anti-inflammatory effects of propolis extract from 10 distinct locations in Indonesia.

The effects of meliponicultural use of on other bee pollinators and pollination efficacy of lemon.

The augmentation of pollination success in lemon ( Eureka) flowers remains contingent on the involvement of bee pollinators. With wild bee pollinator populations declining in agroecosystems, meliponiculture has emerged as a potential option in Indonesia. This study aimed to investigate the effects of meliponicultural use of on diversity, foraging behavior, and monthly population of bee pollinators, as well as lemon pollination efficacy with and without meliponiculture treatment during two periods.

Development of sperm cryopreservation protocol for patin buah, Pangasius nasutus.

The development of sperm cryopreservation for Pangasius nasutus is necessary in order to serve the growing demand of this species through artificial fertilization and the preservation of valuable strains of male broodstocks. In the present study, the basic protocol of sperm cryopreservation for P. nasutus was established by identifying the optimal conditions for optimum cryoprotectant, toxicity of cryoprotectants, extenders, freezing condition and dilution ratio.

Effects of pH and temperature on striped catfish Pangasianodon hypophthalmus juvenile: Data on growth performance and survival rate.

The growth performance and survival rates of juvenile striped catfish, , reared at various levels of pH and temperature were described in this article. Two rearing trials were conducted separately for pH and temperature where both trials lasted for 35 days. One hundred and twenty juveniles (1.

Determination of productivity, yield and bioactivity of propolis extract produced by spp. Cultivated in Modular hives.

This study investigated the effects of microclimate conditions on the activity of , , and cultivated in Modular Hives for producing crude propolis. The hives were equipped with sensors that recorded microclimate data within the hive as well as the total activity of bees entering and leaving the hives. This study also investigated the effects of cultivating , , and with resin towards the productivity of crude propolis and the effects of different extraction methods on the yield, total phenolic content, total flavonoid content, and antibacterial activity of propolis extract produced by the spp.

Enhancing Reproductive Performance of Freshwater Finfish Species through Dietary Lipids.

Dietary lipid manipulation in the feed of commercially cultured finfish is used not only to improve production and culture but also to enhance their reproductive performances. The inclusion of lipid in broodstock diet positively affects growth, immunological responses, gonadogenesis, and larval survival. In this review, existing literature on the importance of freshwater finfish species to aquaculture and the inclusion of dietary lipid compounds in freshwater fish feed to accelerate the reproduction rate is being summarized and discussed.

Sexual dimorphism of Malaysian Mahseer, broodstock reared in captivity: Morphometric measurements dataset.

Despite having high economical value and declining wild population, the aquaculture of the Malaysian mahseer () is still way behind. Crucial information such as on its sexual dimorphism is scarce thus making its broodstock management in captivity challenging. The first step in studying fish sexual dimorphism is by observing and identifying the morphological differences between each sex.

Production of propolis and honey from cultivated in Modular Hives.

Propolis and honey produced by stingless bees are regarded as high economic value products due to their bioactive components, which are significantly influenced by conditions at the cultivation location. This study investigated the effect of cultivation location on the amount and quality of propolis and honey produced by cultivated in Modular  Hives. Fifteen bee colonies were cultivated for at least three months in coffee plantations at two different locations, namely Cibodas and Cileunyi Wetan, Indonesia.

Fermentation of coffee pulp using indigenous lactic acid bacteria with simultaneous aeration to produce cascara with a high antioxidant activity.

Coffee pulp which is a by-product of coffee production contains considerable amounts of phenolic compounds that can be valorised to produce cascara as an antioxidant beverage. The fermentation and drying conditions of the coffee pulp have a great influence on the bioactive compounds in the cascara. This study aimed to investigate the effect of natural fermentation with simultaneous aeration on the phenolic content and antioxidant activity of cascara.

Production of protein hydrolysate containing antioxidant activity from .

Protein hydrolysate is a complex mixture of peptide and amino acids that can be produced from various biomass sources including insects, such as black soldier fly larvae () due to its relatively high protein content. This study aimed to investigate the potential of protein hydrolysate from black soldier fly larvae as a bioactive hydrolysate through enzymatic hydrolysis using bromelain. Black soldier fly larvae contain 25.

Process Intensification of Enzymatic Fatty Acid Butyl Ester Synthesis Using a Continuous Centrifugal Contactor Separator.

Fatty acid butyl esters were synthesized from sunflower oil with 1-butanol using a homogeneous lipase in a biphasic organic (triglyceride, 1-butanol, hexane)- water (with enzyme) system in a continuous setup consisting of a cascade of a stirred tank reactor and a continuous centrifugal contactor separator (CCCS), the latter being used for integrated reaction and liquid-liquid separation. A fatty acid butyl ester yield up to 93% was obtained in the cascade when operated in a once-through mode. The cascade was run for 8 h without operational issues.
