The purpose of this research is the readiness of the science education study program to implement the MBKM curriculum, which is explained through the characteristics of cooperation, lecturer competence, student perception and participation, and analysis of stakeholder needs. The research method uses case study qualitative analysis, and the subjects are teachers, students, and stakeholders in the science education study program. One of the results obtained is the characteristics of the cooperation carried out by the achievement of the graduates. The competencies possessed by lecturers as facilitators in the implementation of MBKM. There is a biased understanding of students' perceptions and involvement in the implementation of MBKM. The stakeholders involved in the preparation of this curriculum have conformity with the needs of the curriculum structure. Furthermore, these results can be used as the basis for the readiness of the Science Study Program in implementing MBKM.
The crab shell waste contains many chitins. When it processed in several chemical processes, it can produce chitosan, which has many benefits and economic value. Chitosan is a linear polysaccharide that consists of N-acetyl glucosamine and D-glucosamine monomers. This study aims to determine the optimum condition of temperature and time of the deacetylation process from the chitin crab shell (Portunus pelagicus) to be chitosan. There are three stages of making chitosan; deproteination, demineralization, and deacetylation. In the deproteination process, crab shell powder was added with a 3.5% NaOH at 65 oC while being stirred for 2 hours. In the demineralization process, crab shell powder was added by 1 N HCl solution for 30 minutes at room temperature. The deacetylation process was done by heating the chitin with NaOH 50% solution with a ratio of 1:10 (w/v) at 90o C for 2 hours. In every step of making chitosan when the stirring has been completed, then it's neutralized using aqua dest and dried in the oven for 24 hours. Chitosan that produced has the highest degree of deacetylation is 79.68%.
During a pandemic like this, they were growing new regulations for conducting online learning, causing further problems in decreasing student learning outcomes in changing learning systems. This study aims to determine the factors that influence student learning interest in online learning with the Discord application, how the use of the Discord application is used in science learning and the effect of the Discord application on student learning outcomes in science learning. This research is a quantitative quasi-experimental study with a pretest-posttest control group design. The number of samples was 64 students from classes 7A and 7B, SMP Negeri 1 Depok, Depok District, Cirebon Regency. Data were obtained through pretest, posttest, questionnaire, interview, and documentation study. The results showed that the attractiveness of the Discord application as an online learning medium could influence students' interest in learning. The connectivity between teachers and students was more effective and efficient in online learning using the Discord application. The opportunity for students to play an active role during the learning process is incredible. The encouragement of motivation through the attitude of the teacher in learning. The influence of online learning media in the form of the Discord application on student learning outcomes in science subjects.
Masyarakat desa mertasinga umumnya bekerja sebagai pengumpul daging rajungan, yang kemudian hasilnya dijual ke pabrik-pabrik, jika masyarakat mempunyai keahlian mengolah daging rajungan tersebut menjadi aneka makanan tentunya akan memberikan nilai ekonomis yang lebih tinggi, jika dibandingkan hanya mengumpulkan daging saja. Tujuan pengabdian masyarakat adalah memberdayakan masyarakat untuk mengolah daging rajungan menjadi nuget rajungan, agar dapat menghasilkan nilai jual yang lebih tinggi jika dibandingkan hanya menjual daging rajungan saja sehingga dapat meningkatkan pendapatan warga. Tehnik sampling yang digunakan adalah simple random sampling. Dengan menggunakan tehnik pengumpulan data dilakukan melalui pengamatan, wawancara dan dokumentasi. Data dianalisis dengan menggunakan tehnik analisa data deskriptif kualitatif. Hasil pengabdian ini adalah keterampilan peserta dalam membuat nugget rajungan yang sehat dan bergizi tinggi tanpa zat adiptif sintetis didapatkan nilai rata-rata peserta sebesar 82,075 %. Kesimpulan dari pengabdian ini adalah pengolahan daging rajungan agar mempunyai nilai jual yang lebih tinggi dapat diolah menjadi nugget, dengan menjaga kualitas rasa dan gizi agar enak dan aman dikonsumsi maka digunakanlah zat adiptif dari bahan alami.
Banyaknya rumus fisika yang harus dikuasai membuat siswa bosan belajar fisika dan materi yang diajarkan. Metode Mnemonik dianggap sebagai metode yang cocok untuk digunakan di sekolah. Tujuan penelitian adalah untuk mengetahui apakah ada perbedaan kemampuan menghafal rumus fisika setelah diajar menggunakan metode mnemonik dan praktek. Penelitian ini dilaksanakan di SMP IT AR-RAHMAN Majalengka pada kelas VIII T.P. 2020/2021 yang melibatkan subjek sebanyak 34 siswa terbagi ke dalam dua kelas, yaitu kelas eksperimen belajar dengan pembelajaran mnemonik dan kelas kontrol belajar dengan pembelajaran praktek. Metode penelitian yang digunakan yaitu Quasi Experiment dan desain penelitian two group randomized subject pretest dan posttest. Adapun teknik pengumpulan data berupa tes kemampuan menghafal rumus-rumus fisika dan kuesioner. Analisis data yang digunakan yaitu uji N-gain, Uji Wilcoxon, dan uji t dua pihak.Hasil penelitian menunjukan terdapat perbedaan kemampuan menghafal rumus fisika pada materi tekanan zat antara siswa yang mendapatkan pembelajaran mnemonik dengan siswa yang mendapatkan pembelajaran praktek.
