Abstract

This study aims to determine the differences in variations of crude papain enzyme concentration and optimal fermentation time on the microbiological quality of skipjack tuna (Katsuwonus pelamis L.) fish sauce. This research is an experimental study with two variables: 2 different enzyme concentrations (5% and 10%) and 3 different periods (3, 7 and 11 days). The microbiological tests include the Escherichia coli contamination test, total microbial test, and total lactic acid bacteria test. Physical tests include water content tests, pH tests, and organoleptic tests. The results showed that the enzyme concentration and fermentation time affected the microbiological quality of skipjack tuna sauce. The sample with an enzyme concentration of 10% and a fermentation time of 11 days was the best sample of skipjack tuna fish sauce because no E. coli bacteria were found (negative), the total BAL test result was 8.2 x 103 cfu/mL, and the TPC result was 7.1 x 103 cfu/mL which meets SNI standards for Fish Sauce No. 01-4271-1996. This sample also had the best organoleptic test results: a non-fishy aroma, savory taste, and dark brown color. Based on the pH test, samples with enzyme concentrations of 5% and 10% and a fermentation time of 3 days have a pH value that meets the requirements, namely 5.88 (pH requirement 5-6). The results of the water content test showed that all samples did not meet the standards.

Abstract

21st-century learning demands mastery of critical thinking, creativity, communication, and collaboration skills. However, these skills are difficult to develop if the learning approach still focuses on lectures and memorization. Deep learning, which emphasizes meaningful understanding, reflection, and application in real life, is one potential strategy for bridging this gap. Unfortunately, most previous research has only examined deep learning in digital contexts, although many schools in Indonesia still have limited access to technology. The service aims to socialize the process of implementing deep learning that can be applied in classroom environments with limited access to technology, especially to describe student interactions that represent their skills in understanding, applying, and reflecting. With a socialization approach using two stages of activities, namely the process of implementing activities and evaluation, activities were carried out for grade 11 students at SMA Swadaya Karya Ciwidey, Bandung Regency. The results show that the application of deep learning-based learning encourages students to understand concepts more critically (such as distinguishing between laziness and procrastination), relate the material to authentic experiences, and develop reflective problem-solving strategies. College students also show improvements in engagement, self-awareness, and high-level thinking skills, even without the support of digital technology. This study underscores the importance of learning designs that focus on immersive learning experiences that are relevant to students' lives, even in the context of limited resources.
