Abstract

Banana tape is one of the innovations in processing bananas into new processed products that can be enjoyed by the community, which is almost the same as making tape in general. The purpose of this study was to determine the right variation of ragi concentration on the physical and chemical characteristics of kepok banana tape. This type of research is experimental with the Completely Randomized Design (RAL) method with variations in ragi concentration, namely 0.5 grams, 1 gram, 1.5 grams, 2 grams and 2.5 grams with a fermetation time of 3 days. The parameters of this study include physical analysis (taste, flavor, color and texture) and chemical analysis (glucose, alcohol and pH). The results showed that ragi concentration of 0.5 gram produced the best organoleptic test of taste 3.75, aroma 3.4, color 3.6 and texture 3.45. Chemical tests showed that a ragi concentration of 1.5 grams produced the best results in glucose levels of 7.9%, alcohol 1.24% and pH 4.41. This study has the potential to be used as a contextual chemistry learning medium, particularly in understanding fermentation processes, pH changes, and biochemical transformations in everyday food products.

Abstract

Steaming is a very important factor in the processing of food ingredients, especially kepok bananas before being fermented into tape. This study was to determine the effect of steaming time on the quality of kepok banana tape seen from the chemical characteristics including pH value determined using a pH meter, sugar content with the phenol sulfate method, alcohol content with the acid-base titration method, and organoleptic testing by 15 panelists. The bananas used were half-ripe kepok bananas from Dolo District, Sigi Regency, with variations in steaming time of 25, 30 and 35 minutes. The results showed that kepok banana tape with a steaming time of 25 minutes had a pH of 4.88; sugar content 12.62%; alcohol content 1.47%; color preference 3.4; aroma 2.8; texture 3.6 and taste 2.8. Tape with a steaming time of 30 minutes had a pH of 4.85; sugar content 16.37%; alcohol content 1.52%; color preference 3.5; aroma 2.6; texture 3.2; and taste 3.1. And tape with a steaming time of 35 minutes has a pH of 4.85; sugar content 10.57%; alcohol content 1.61%; color preference 3.4; aroma 3; texture 3.4; and taste 3.4. Based on the results of chemical and organoleptic characteristic tests, the best quality of banana kepok tape is tape with a steaming time of 35 minutes. This study provides educational relevance by illustrating the application of chemistry concepts such as acid-base reactions, fermentation, and analytical techniques in real-world food processing, making it a potential contextual learning material in science education.

Abstract

Lesson Study is an approach to improving the quality of learning carried out by teachers collaboratively, with the main steps of designing learning to achieve goals, implementing learning, observing the implementation of the learning, and reflecting to discuss the learning studied and improve it and plan the next lesson. The main focus of implementing lesson study is student activities in class, with the assumption that student activities are related to teacher activities while teaching in class. In implementing PPL Education at UNTAD, the implementation of Lesson Study is integrated with the implementation of clinical supervision. The aim is to improve the quality of student learning outcomes and learning products. However, what is still experienced by the world of education today is that more than 50% of teachers do not understand and pay less attention to achieving and improving pedagogical and professional competence, including in schools in Palu City. To teach teachers to implement LS, it is not enough if teachers are introduced to what and how to implement it, but they also need to be introduced to why, what the long-term and short-term goals of implementation are. Teachers also need to be introduced to what the requirements are, what the difficulties and obstacles are in implementation, and that the main requirement for implementation is a commitment to benefit the nation's children. One of the critical characteristics of intelligent humans is that they not only know something but also how to respond and act on it.AbstrakLesson Study merupakan suatu pendekatan peningkatan kualitas pembelajaran yang dilaksanakan oleh guru secara kolaboratif, dengan langkah-langkah pokok merancang pembelajaran untuk mencapai tujuan, melaksanakan pembelajaran, mengamati pelaksanaan pembelajaran tersebut, serta melakukan refleksi untuk mendisukusikan pembelajaran yang dikaji tersebut dan menyempurkannya dan merencanakan pembelajaran berikutnya. Fokus utama pelaksanaan Lesson Study adalah aktivitas siswa di kelas, dengan asumsi bahwa aktivitas siswa tersebut terkait dengan aktivitas guru selama mengajar di kelas. Dalam penyelenggaraan PPL Kependidikan di UNTAD, penerapan Lesson Study diintegrasikan dengan penerapan supervisi klinis. Tujuannya untuk meningkatkan kualitas hasil belajar dan produk belajar siswa. Namun yang masih dialami oleh dunia pendidikan sampai saat ini adalah lebih besar 50% guru yang kurang memahami dan kurang memperhatikan pencapaian dan peningkatan kompetensi pedagogik dan professional, termasuk di sekolah-sekolah yang ada di Kota Palu. Untuk membelajarkan guru melaksanakan LS tidak cukup bila guru dikenalkan pada apa dan bagaimana melaksanakannya, tetapi juga perlu dikenalkan mengapa, apa tujuan jangka panjang dan jangka pendek pelaksanaan. Guru juga perlu dikenalkan pada apa persyaratannya, apa kesulitan dan hambatan pelaksanannya, dan bahwa persyaratan utama pelaksanannya adalah adanya komitmen untuk memaslahatkan anak bangsa. Salah satu ciri kritis manusia cerdas yakni tidak hanya mengetahui sesuatu tetapi juga bagaimana menanggapi dan menindaklanjutinya.
