Shrimp is a raw material source of animal protein which is rich in amino acids. The types of amino acids commonly found in shrimp are glutamic acid, aspartic acid, arginine, lysine, leucine and alanine. The amino acid content in shrimp is different for each treatment given to the shrimp. The aim of this research is the characteristics of smoked white shrimp protein functional groups using several cooking methods and protein damage in smoked white shrimp products using several cooking methods based on protein functional groups. Testing for smoked white vaname shrimp quality standards refers to SNI 2728-2018. Chemical testing parameters were carried out using Fourier-Transform Infrared Spectrometer (FTIR), Protein and Amino Acid Profile testing. The parametric data results were analysed using One-Way ANOVA. The results showed that the protein value of smoked vaname shrimp with different cooking methods was significantly different (p<0.05). The results of the FTIR test for smoked vaname shrimp gave rise to spectrum peaks in the wave range 3300cm-1 -3600cm-1 which indicated the presence of amide compounds (NH2). This is also supported by the distribution of spectrum peaks in the fingerprints zone at wavelengths of 500cm-1 -1500cm-1. The absence of a spectrum peak in the spectrum range 1600cm-1 -1690cm-1 indicates that secondary proteins have not been formed as markers of protein damage.The highest protein value was found in the control smoked white vaname shrimp at 38.84% and the smallest protein value was found at the oven method at 27.80%.The amino acid profile test shows higher values of glutamic acid, aspartic acid, arginine, glycine, alanine, leucine and lysine. The organoleptic values of all cooking methods were found to have varying results from the parameters of appearance, smell and texture in each cooking method treatment showing results that were not significantly different.

“…Fitri et al, (2019) stated that the nervous system is biology topic that contains cognitive material that is quite complicated, so it requires innovation in its delivery. In addition, Kurniawati & Jailani (2020) stated that metabolism topic is a concept that uses many terms in Latin which makes it difficult for students to understand it.…”

<p>Students are demanded by school assignments, and many of them feel under pressure when learning biology. This situation is a trigger for academic stress which has an impact on student achievement. This study aims to identify and compare the factors that influence academic stress on students studying biology at the senior high school level. The research method used was an ex post facto survey using a sample of 54 students with an age range between 16-18 years. Data were obtained through a questionnaire with 9 scales of answer choices and interviews. The results showed that the level of preference for biology subjects for both public and private high school students was quite good, but most students experienced academic stress with a fairly high category in terms of motivation, self-confidence, the education system, teachers, and school conditions. This research implies that teachers are expected to create learning strategies by paying attention to the psychological conditions of students so that student learning outcomes can be maximized.</p>

“…Hal ini menyebabkan rendahnya hasil belajar pada mahasiswa. Hasil penelitian Kurniawati & Jailani (2020) menyatakan bahwa rendahnya hasil belajar pada mata kuliah Biokimia disebabkan oleh kesulitan mahasiswa dalam menyelesaikan permasalahan dalam Biokimia seperti struktur kimia dan hafalan materi sehingga minat belajar mahasiswa kurang. Materi dalam mata kuliah Biokimia di perguruan tinggi berisi tentang konsep yang memuat mengenai pengantar Biokimia, biomelekuler, metabolisme, enzim, replikasi, dan ekspresi gen.…”

Biokimia adalah ilmu yang mengkaji mengenai substansi dan komposisi pada makhluk hidup. Mata kuliah Biokimia termasuk mata kuliah yang sulit untuk dipelajari oleh mahasiswa. Kesulitan belajar pada materi biokimia menyebabkan hasil belajar mahasiswa Tadris Kimia cenderung rendah. Tujuan penelitian ini adalah menganalisis kesulitan belajar mahasiswa tadris kimia di UIN SATU Tulungagung pada mata kuliah Biokimia. Metode penelitian menggunakan deskriptif analisis. Teknik analisis data dilakukan dengan tinjauan literatur. Metode pengumpulan data pada penelitian ini dilakukan dengan observasi, penyebaran angket, dokumentasi, wawancara dosen, serta wawancara mahasiswa. Instrumen penelitian ini terdiri dari lembar wawancara dosen dan mahasiswa, lembar observasi, dan juga lembar angket. Subjek penelitian adalah mahasiswa Tadris Kimia UIN SATU Tulungagung yang telah menempuh mata kuliah Biokimia sebanyak 70 mahasiswa. Teknik pengambilan sampel menggunakan purposive sampling. Hasil penelitian dan membahasan menunjukkan bahwa kesulitan belajar pada mahasiswa dipengaruhi oleh beberapa faktor diantaranya kapasitas dosen dalam mengajar, kemampuan mahasiswa dalam menyerap materi pembelajaran, kualitas lingkungan pembelajaran, dan media pembelajaran. Upaya yang dapat dilakukan dalam rangka mengatasi kesulitan belajar pada mahasiswa tadris kimia materi Biokimia adalah dengan melalui pengembangan bahan ajar yang lebih menarik, penggunakan model pembelajaran interaktif, pembuatan video pembelajaran, modul, buku petunjuk praktikum, diskusi interaktif antara dosen dengan mahasiswa, dan kegiatan laboratorium.
