Abstract

Lemea, a traditional fermented food of the Rejang people in Bengkulu, is made from young bamboo and fish. The fish commonly used in the making Lemea is Mozambique tilapia or Mujair (Oreochromis mossambicus). The fermentation process typically lasts between 3 to 7 days. This study aimed to assess the sensory characteristics, including taste, color, texture, and aroma, of Lemea, based on the preferences of panelists. The variations examined were fermentation duration, and the amount of Mujair fish added. The research followed a completely randomized design, incorporating three fermentation durations (24, 96, and 144 hours) and three fish quantities (250 grams, 500 grams, and 750 grams). Sensory evaluations were conducted on the fermented samples, encompassing taste, aroma, texture, and color. The data revealed that the most favored taste and texture of Lemea were achieved with 500 grams of fish and a fermentation duration of 144 hours (J2W3). Likewise, the preferred aroma and color were observed in the sample with 750 grams of fish and 24 hours of fermentation (J3W1). The data analysis indicated that the sample with 500 grams of fish and a fermentation duration of 144 hours (J2W3) exhibited the most favorable sensory characteristics (taste, aroma, texture, and color). Thus, the quantity of fish added and the duration of fermentation influenced the sensory attributes of Lemea.

Abstract

Green lettuce (Lactuca sativa L.) is a vegetable crop that is in great demand by the public, but its production is relatively low so that it cannot meet the high market demand. One of the efforts to increase the production of green lettuce plants is by applying organic fertilizer. The purpose of this study was to determine the content of C, N, P, K elements, the effect of compost application for growth and optimal dosage. The research method used a complete randomized design (CRD) four treatments namely Control, A (dose of 60 g), B (dose of 120 g) and C (dose of 180 g) with 5 replications. Data from the study were analyzed using the Anova test, significant data continued with the DMRT 5% further test. Testing the effect with simple liner regression analysis. The results showed that compost gave a blackish brown color after 35 days and had no odor and obtained nutrient values of C (41,77%), N (6,92%), P (0,09%) and K (0,12%). The treatment of compost variations produced plant height of 26,80 cm, number of leaves of 10,60 leaf, plant wet weight of 22,40 gram, root weight of 0,57 gram, root length of 12,94 cm leaf area of 130,06 cm² with significant results, while chlorophyll A (0,19 mg/L) and total (0,616 mg/L) levels had insignificant results. The conclusion of the research is that the compost of banana stalks and cow blood meal contains C by 41,77%, Total N by 6,92%, Total P by 0,09% and Total K by 0,12%. Banana pith compost and cow blood flour had a significant effect on all parameters of green lettuce plant growth except leaf chlorophyll content at the most optimal dose was treatment A (dose of 60 g).

Abstract

Spodoptera frugiperda is a polyphagous insect that has a main host of corn plants and attacks corn plants in the vegetative to generative phase. Besides corn, S. frugiperda has been reported to have other alternative host plants. The purpose of this study was to analyze the type of S. frugiperda attack most often found on alternative host plants and analyze the types of plants other than corn that are most often used as alternative hosts by S. frugiperda in Bantul Regency. This research was conducted in Bantul Regency in January-April 2023. Samples were taken from two villages from each sub-district in Bantul Regency. The research was conducted using survey method to determine the village as the research location and purposive method for sampling the alternative host plants. Samples taken were plants around corn fields with symptoms of S. frugiperda attack in the form of perforated leaves or traces of feces from feeding activities or S. frugiperda egg packages. The results of this study showed that 29 plant species from 13 families were attacked by S. frugiperda in Bantul Regency. The most common type of S. frugiperda attack was bite marks (60%). The most commonly attacked plant species came from the Poaceae family, namely elephant grass (Pennisetum purpureum). The conclusion of this study is that S. frugiperda has attacked plants other than corn in 17 sub-districts in Bantul Regency.

Abstract

Telenomus remus is parasitoid on many Lepidpoteran. Morphological analysis on T. remus is important to understand their behavior and assest the quality of parasitoid comes from the mass rearing process. However, the information of T. remus body setae cuticle characteristics were limited. This study aimed to explore the body setae on the mesonotum of of T. remus by using electron microscopy analysis and characterize their cuticle characterisics to infer the putative function of the body setae. The results showed structures that support the body setae on the mesonotum as mechanoreceptor. The structure included the long and dangling seta peg, a socket, and a gap between a socket and the base of the seta peg. The putative function related to the biology and behavior of T. remus were discussed.

Abstract

This research explores the rapid environmental impact of the batik industry, particularly concerning batik waste pollution, especially from the heavy metal copper (Cu). Untreated batik waste can have adverse effects on the environment. The study highlights the potential of the water fern plant (Salvinia molesta) as a heavy metal phytoremediator, specifically for Cu, by activating phytochelatin synthase. The research aims to determine the most effective waste concentration for Cu absorption by water ferns, measure the reduction in Cu levels after phytoremediation treatment, evaluate post-phytoremediation water quality, and observe PCS gene expression in the roots and leaves of water ferns. A static method is employed with variations in waste concentrations. Data analysis utilizes one-way ANOVA for Cu level reduction and changes in water quality. The results indicate that the most effective wastewater concentration for absorbing heavy metal copper (Cu) using water fern (Salvinia molesta) is 2%. The highest reduction in heavy metal copper (Cu) concentration after phytoremediation treatment with water fern (Salvinia molesta) is 41.48%. Water quality post-phytoremediation treatment using water fern (Salvinia molesta) at all concentrations exhibits improvement with an increase in dissolved oxygen (DO) levels. The expression of the phytochelatin synthase (PCS) gene in the leaves and roots of water fern (Salvinia molesta) confirms the role of the PCS gene in binding heavy metal copper (Cu) to the plant's vacuole.
