Abstract

Edible coating is a barrier, thin layer of consumable material to maintain moisture and slow down the respiration process of a product. In order to preserve the quality of red chili, this study aims to find the ideal taro starch concentration to use as an edible covering. Six treatments of taro starch concentration—0, 1, 2, 3, 4, and 5%—were used in experimental research utilizing a completely randomized design (CRD). Hedonic organoleptic testing produced the data. Analysis of variance (ANOVA) is then performed based on the level of panelist preference, and an LSD test is applied if there is a significant difference. The findings indicated that a 5% concentration of taro starch works best as an edible covering material to preserve the quality of red chili

Abstract

Intensive ponds often experience a decrease in water quality and cause ponds to bloom due to the fertility of the pond bottom due to the buildup of organic material originating from leftover feed, feces and the remains of dead shrimp. The aim of this research is to determine the relationship between water quality and phytoplankton abundance in intensive pond types with different densities in Bayeman Village, Probolinggo Regency. The research was carried out from January to March 2023. Samples were taken using the purposive sampling method in 6 different pond plots. Phytoplankton analysis was carried out at the Laboratory of the Sand Source Freshwater Fisheries Technical Implementation Unit and the Hydrobiology Laboratory of the Fish Resources Section of the Faculty of Fisheries and Marine Sciences. Measurement of in situ water quality parameters, namely temperature, pH, brightness, DO, TDS, light intensity, salinity and ex situ nitrate, phosphate and ammonia using spectrophotometric methods. The correlation test results of physico-chemical parameters related to phytoplankton abundance have a strong and heterogeneous relationship only with the orthophosphate parameter

Abstract

The purpose of this study was to investigate the effect of the scaffolding guidance provision on students' science process skills (SPS) in a project-based learning (PjBL) about acid and base concepts. A quasi-experimental research design was applied to collect data using a pre-validated SPS-observation. An experiment group of students of SMAN 3 in Jambi City had learnt the concepts using a scaffolding-assisted PjBL while a control group from the same school had learnt it using PjBL without scaffolding. Data was analyzed using t-test assisted by SPSS software. The results of analyses showed that the SPS of the experiment group was higher than their counterparts’ SPS. Statistical analyses showed an effect of the use of the scaffolding guidance on the students’ SPS with the p-value of .000 < .05. The experiment students had been observed achieved the indicators of the SPS during the learning process while their counterparts had not; and those may be due to the benefits of the provision of the scaffolding guidance that eased them to do their tasks. It can be concluded that the use of scaffolding guidance is able to overcome the problems faced by students in a project-based learning that thus improve their SPS

Abstract

This study aims to determine the decrease in glucose levels, MDA levels, and histopathological appearance of the pancreatic organs of Wistar white rats after administration of the ethanol-water fraction of longjack root. This study used a completely randomized design with four treatment groups and six replications. The treatment consisted of normal control, negative control (Na-CMC 0.5% 5 ml/200 g body weight), positive control (glibenclamide 0.09 mg/200 g body weight), and treatment of the ethanol-water fraction of longjack root with a dose of 500 mg/kg body weight. The results showed that the ethanol-water fraction of longjack root at a dose of 500 mg/kg body weight had antidiabetic activity comparable to that of glibenclamide at a dose of 0.09/200 g body weight, namely blood glucose levels and MDA levels in white rats of 123.55 mg/dl and 2.83 nmol/ml. The results of histopathological analysis of the pancreas of white rats showed that administration of the ethanol-water fraction of longjack root could repair damage to the islets of Langerhans due to the administration of streptozotocin-nicotinamide.
