Abstract

This study was conducted to describe students’ perceptions about the genetic course, laboratory experiment, laboratory facilities, and also students’expectations about the development of the virtual laboratory as an alternative experiment in Genetics Courses. A descriptive quantitative method was used in this study. The participants involved were 49 students enrolling in a genetics course at a public university in Banten, Indonesia. Data were collected through a set of questionnaires. To analyze the data,we employed a descriptive quantitative approach in the form of a percentage. The results showed that the genetic course was considered difficult by the students. The reason is that the material is abstract, and the source of learning is difficult to understand. The most commonly used learning media in the lecture is Power Point.Learning strategies are oftenused,i.e.,the discussions and laboratory work in the laboratory. Students need interesting, communicative, and interactive learning media. The student response is enthusiastic about virtual laboratory development. The expected virtual laboratory criteria are can be used offline, looks interesting, easy to operate, and containsaudio-visual.

Abstract

Evolutionary  course materials in the Biology Department, State University of Padang inadequate to guide students to think critically, giving rise to various problems. One of the problems that arise are student learning outcomes at the course of evolution tend to be low, because the students are not familiar with the assessment instruments developed higher-order thinking skills. Problem thinking skills of students that is low, overcome by applying authentic asessment in the textbook used. Qualitative test goal is to produce an authentic assessment of molecular evolution in the textbook is good, and can improve higher-order thinking skills of students. Qualitative test is one of the stages of research development, adapted from the model of the development of 4D-models Thiagarajan, ie develop stages. Qualitative test conducted on students of the Department of Biology State University of Malang, because the student has more accustomed to using assessment that guide higher-order thinking skills, so the results will be better. Qualitative assessment test showed that there were several assessment instruments that need to be revised, in accordance with the values obtained by the students on the posttest. Based on these results, it can be said that the authentic assessment in the textbook of molecular evolution has reached the category of good and fit for use in the teaching of Evolution in Higher Education.Kata kunci: uji kualitatif, asesmen autentik, buku ajar evolusi molekuler

Abstract

Perubahan pola konsumsi masyarakat yang sadar akan pentingnya gizi dan kesehatan, menyebabkan konsumsi ayam ras pedaging cenderung meningkat. Ayam ras pedaging yang paling banyak dikonsumsi adalah jenis Ayam Broiler. Salah satu kandungan tertinggi pada daging ayam broiler selain lemak adalah protein. Daging ayam mudah mengalami penurunan kualitas selama penyimpanan. Penelitian ini bertujuan untuk mengetahui pengaruh waktu inkubasi terhadap konsentrasi protein jaringan otot ayam broiler serta mengetahui profil protein jaringan otot ayam broiler pada waktu inkubasi yang berbeda. Berdasarkan hasil uji Anava, waktu inkubasi berpengaruh terhadap konsentrasi protein jaringan otot ayam broiler. Hasil uji Post-Hoc Duncan menunjukkan jaringan otot Ayam Broiler yang disimpan mulai 1 jam, 3 jam, 5 jam, 7 jam, 9 jam dan 11 jam konsentrasi proteinnya menurun dan berbeda nyata dibandingkan dengan inkubasi 0 jam. Visualisasi protein memperlihatkan adanya perbedaan ketebalan pita protein setelah jaringan otot ayam disimpan selama 1 jam hingga 11 jam, adanya pita protein dengan BM 53 kDa yang hilang setelah jaringan otot ayam disimpan selama 11 jam serta adanya pita protein dengan BM 60 kDa yang muncul setelah jaringan otot disimpan selama 7 jam.
PENGEMBANGAN MODUL BERBASIS PENELITIAN ANALISIS AKTIVITAS FOSFORILASI PROTEIN MEMBRAN SPERMATOZOA KAMBING UNTUK MATAKULIAH TEKNIK ANALISIS BIOLOGI MOLEKULER Zukmadini, Alif Yanuar; Lestari, Umie; Sari, Murni Sapta

Abstract

Penelitian ini bertujuan untuk 1) menghasilkan modul berbasis penelitian analisis aktivitas fosforilasi protein membran spermatozoa kambing; 2) untuk mengetahui aktivitas fosforilasi protein membran spermatozoa kambing PE dan Boer. Penelitian ini merupakan penelitian pengembangan yang menggunakan model pengembangan Borg & Gall (1983) yang dibatasi sampai lima tahap yaitu, research and information collecting, planning, develop preliminary form of product, preliminary field testing, dan main product revision. Analisis aktivitas fosforilasi protein membran spermatozoa dilakukan dengan beberapa prosedur laboratorium yaitu, isolasi protein, elektroforesis, elektroelusi protein 43 kDa, dan uji aktivitas fosforilasi. Metode penelitian ini adalah deskriptif kuantitatif yang menggunakan instrumen berupa lembar validasi. Hasil validasi menunjukkan bahwa persentase kevalidan modul dari ahli materi sebesar 95,40%, dari ahli bahan ajar sebesar 99,49% dan dari uji coba kelompok kecil sebesar 86,35%. Keseluruhan persentase yang diperoleh termasuk ke dalam kategori valid. Hasil penelitian mengenai aktivitas fosforilasi protein 43 kDa menunjukkan bahwa jumlah ATP yang difosforilasi pada protein membran spermatozoa kambing PE sebesar 179 ppm, sedangkan pada kambing Boer sebesar 159,5 ppm. Unit aktivitas fosforilasi protein 43 kDa pada kambing PE sebesar 69,29 x 10-2 µmol/mL.menit, sedangkan pada kambing Boer sebesar 61,61 x 10-2µmol/mL.menit.Keywords       : Modul berbasis penelitian, aktivitas fosforilasi, teknik analisis biologi molekuler
