Abstract

Liberika coffee is one of the most popular types of coffee because of its distinctive taste, besides having advantages, Liberika coffee also has many disadvantages, namely the value of caffeine and high organic acids contained in liberika coffee, so that if excessive coffee consumption can have a negative impact on health. One alternative for coffee to be enjoyed by all people is to produce low-acid coffee with a fermentation method using yeast. However, if the duration of fermentation and the concentration of yeast are not appropriate will result in the formation of aliphatic acids which can result in fermentation defects and the taste of coffee decreases. The purpose of this study was to m endapatkan k onsentrasi yeast and fermentation time is rightto produce low-acid coffee powder from liberika coffee after going through the fermentation process. This study uses Factorial RAK pattern with two factors namely Yeast Concentration (1.5%; 2.5%; 3.5%) and Fermentation Duration (4 hours, 8 hours, 12 hours) each treatment was repeated 3 times. The data obtained was analyzed by ANOVA. Then a further test using BNT 5% is carried out and if the results are significantly different, it will be continued using 1% BNT. The results showed that the best yeast concentration and fermentation time were found in the treatment with 1.5% yeast concentration and 8 hours fermentation time which produced a total acid of 0.58% and water content of 5.49%. levels of caffeine, k adar ash, and kealkalian ash, with successive values 1, 1 %, 1.8% , and 61 1N NaOH. Kopi liberika adalah salah satu jenis kopi yang banyak digemari dikarenakan citarasanya yang khas, Selain memiliki kelebihan, kopi liberika juga memiliki banyak kekurangan yaitu nilai kafein dan asam organik yang tinggi terkandung dalam kopi liberika, sehingga apabila mengkonsumsi kopi dalam jumlah yang berlebih dapat berdampak negatif untuk kesehatan. Salah satu alternatif agar kopi dapat dinikmati oleh semua kalangan adalah dengan memproduksi kopi rendah asam dengan metode fermentasi menggunakan ragi. Namun jika lama fermentasi dan konsentrasi ragi tidak tepat akan mengakibatkan terbentuknya asam alifatik yang dapat mengakibatkan cacat fermentasi dan cita rasa kopi semakin menurun. Tujuan dari penelitian ini adalah untuk mendapatkan konsentrasi ragi dan lama fermentasi yang tepat untuk menghasilkan bubuk kopi rendah asam dari kopi liberika setelah melalui proses fermentasi. Penelitian ini menggunakan RAK pola Faktorial dengan dua faktor yaitu Konsentrasi Ragi (1,5%; 2,5%; 3,5%) dan Lama Fermentasi (4 jam, 8 jam, 12 jam) setiap perlakuan diulang sebanyak 3 kali. Data yang didapat dianalisa dengan ANOVA. Kemudian dilakukan uji lanjut mengggunakan BNT 5% dan bila hasilnya berbeda nyata akan dilanjut menggunakan BNT 1%. Hasil penelitian menunjukkan bahwa konsentrasi ragi dan lama fermentasi terbaik terdapat pada perlakuan dengan dengan konsentrasi ragi 1,5% dan lama fermentasi 8 jam yang menghasilkan total asam sebesar 0,58% dan kadar air sebesar 5,49%. kadar kafein, kadar abu, dan kealkalian abu, dengan nilai berturut-turut 1,1 %, 1,8%, dan 61 1N NaOH.

Abstract

Motivation to learn is needed in the learning process at school so that learning objectives can be achieved as expected. Learning motivation This research was conducted on the basis of findings of problems that arise in the school environment, especially in the education of elementary school children, namely related to students' learning motivation. This has been proven at school, where some children show a lack of enthusiasm and even do not want to participate in the learning process, for example children do not pay attention to the teacher's explanations and are busy telling stories with their friends. This problem demands the need for a learning media that provides Achievement Star rewards. The method used is a comparative descriptive method with a qualitative approach and a quantitative approach which aims to compare the motivation of students' learning levels without using achievement stars. This research involved 29 children. Data was collected through classroom observations during learning and documentation. Based on analysis of previous research data, it was found that before there was concrete media with awarding achievement stars, children were less enthusiastic about participating in learning activities. The research results show that using concrete media by giving Achievement Stars can motivate children's learning. For example, children are enthusiastic about learning, active when asking questions or asking questions during learning activities, carrying out assignments given by the teacher until they are finished. By giving this achievement star, educators are helped so that they can increase children's learning motivation. The research results showed that there was an increase from pre-cycle, to cycle 1, then cycles II, and III. It can be seen from the percentage of students' learning motivation in the pre-cycle, 28% was categorized as very poor, in cycle I it was 51.72% categorized as poor, in cycle II it reached 69%, it was categorized as sufficient and in cycle III it reached 93.10%, it was categorized as very good. Thus, it can be stated that the application of learning using concrete media and achievement stars can increase students' learning motivation in class II Elementary School Civics learning
