Abstract

Due to the increasing demand for gelatin alternatives, iota carrageenan, a polymer derived from seaweed, is being explored as a potential base material for soft capsule production. However, the rheological properties of iota carrageenan alone are insufficient for commercial manufacturing, necessitating the addition of fillers such as modified starches. This study evaluates the performance of iota carrageenan-based soft capsule shells using modified cassava, potato, and sago starches as fillers. Various mechanical and rheological properties were assessed, including elongation, stickiness, tensile strength, and viscosity. The results demonstrated that modified cassava starch provided the best overall balance of mechanical properties, exhibiting superior moldability (47.56 mm elongation), flexibility, and moderate stickiness (567.45 gf). Scanning Electron Microscopy (SEM) analysis revealed that cassava starch capsules had a more uniform outer surface with smoother internal morphology than other starches. These findings suggest that modified cassava starch is a promising candidate for large-scale production of high-quality soft capsules.

Abstract

This study aims to explain the types and purposes of directive speech acts contained in Ustadz Hannan Attaki's lecture entitled "If I'm Harmed, What Should I Do?" This study adopted a descriptive qualitative method with a focus on pragmatics. The data source came from lecture recordings posted on the YouTube platform, while the data analyzed were utterances containing directive speech acts. Data collection was carried out by listening, recording, and taking notes, then the data were analyzed using an interactive analysis model that includes data reduction, data presentation, and drawing conclusions. The results of this study indicate that Ustadz Hannan Attaki's lecture contains various types of directive speech acts, such as prohibitions, advice, and commands. The functions of these directive speech acts include preventing or prohibiting certain actions, providing advice and guidance to listeners, and directing listeners to take actions that are considered positive and useful. These findings indicate that directive speech acts have a significant role in conveying persuasive da'wah messages and increasing listeners' moral awareness.

Abstract

The study analyzes the process of first language acquisition in early childhood from a psycholinguistic perspective with a focus on neurological cognitive foundations and language disorders in Indonesian language education, identifying key neural mechanisms, inhibiting factors, and recommendations for pedagogical interventions. A qualitative approach with an interpretive paradigm is used through literature studies from psycholinguistics, child neurology, and Indonesian language education journals, analyzed following the Miles and Huberman model which includes thematic data reduction, matrix and diagram presentation, and triangulation for conclusions. Major neurological mechanisms include Broca's activation for speech production, Wernicke's for semantic comprehension, as well as high synaptic plasticity that processes Indonesian phonemes from babbling to complex sentences at the age of 0-6 years, supported by Chomsky's Universal Grammar theory and connectionist models. Disorders such as speech delay, expressive-receptive language, articulatory phonological, pragmatic autism, and stuttering disrupt the cortico-striatal and prefrontal cortex pathways, leading to limitations in vocabulary, syntax, and social interaction. Integration into the Indonesian education curriculum through sensory stimulation modules, NLP exercises, motor games, singing rhythms, and neuroimaging-based teacher training restores neural connections, accelerates lexicon milestones, and forms an inclusive ecosystem with continuous evaluation via observation and biofeedback.
