The Differences Effect between Pond Types and Maggot Allotments on The Protein and Fat of Tilapia Meat
Get PDFTilapia was one of the freshwater fish commodities that were widely consumed, so the demand for tilapia increased and impacted the high price of tilapia feed. Therefore, maggots can be used as additional fish feed, and recently there have been many variations of pond types in tilapia farming. This study aimed to determine the interaction between pond types and maggot allotments for protein and fat in tilapia meat. This study used two types of pools: tarpaulin and drum. The subjects used in this study were tilapia, with as many as 30 fish per pond. The dependent variables in this study were the protein and fat of tilapia meat. This study used the factorial method with a completely randomized design (RAL) with four treatments; each of the four tests consisted of A1B1 (Tarpaulin pool and maggots), A1B2 (Tarpaulin pool without maggots), A2B1 (Drum pool and maggots), and A2B2 (Drum pool without maggots). Data analysis was done using ANOVA with a significance level of 5% if there is an effect continued Duncan test. The results of this study showed no noticeable effect on meat protein (0.253>0.05) and meat fat (0.067>0.05) tilapia

Why Eucalyptus Citriodora Potential as Biopesticide ?
Get PDFVarious efforts have been made to eliminate or at least reduce the negative impact of chemical pesticides that are currently widely used. One of these efforts is to use other effective control alternatives, such as bio-pesticides/botanical pesticides. Eucalyptus citriodora essential oil was previously better known in traditional medicine. However, many studies have shown that this essential oil has much potential to be used as a biopesticide. This article reviews the biopesticide potential of E. citriodora essential oil, including its herbicidal, bactericidal, fungicidal, nematicidal, insect-repellent, and insecticidal activities. E. citriodora oil contains citronellal, citronellol, 1,8-cineole, isopulegol, ?-pinene, and citronellyl acetate. Citronellal and citronellol are one of the main toxins in E. citriodora essential oil. However, this review shows that the oil has a broad spectrum of biological activity, making it a simple and environmentally friendly pesticide
