Abstract

Mount Ijen is a prominent region for peaberry Robusta coffee beans, which has entered international markets. Accurate real-time estimation of its chemical components is crucial for export activities. This study evaluated moisture content, lipid, and caffeine in Robusta peaberry coffee beans from Ijen using FT-NIRS (Fourier Transform – Near Infrared Spectroscopy). A total of 50 samples were scanned in triplicate, generating 150 spectral data points. The data were optimized for wavelength selection and pre-treated using Standard Normal Variate Transformation (SNV), Second Derivative (dg2), Multiplicative Scatter Correction (MSC), and normalization. Results showed that FT-NIRS proved effective for rapid and accurate estimation of these components. The best calibration model used Kubelka-Munk transformation with dg2 pre-treatment in the 1000-2500 nm wavelength range. Optimal Partial Least Squares (PLS) factors were PLS 4 for lipid content (R2 = 0.98, SEP = 0.013%, SEC = 0.012%, CV = 0.81, RPD = 2.03, consistency = 95.21%), PLS 5 for moisture content (R2 = 0.94, SEP = 0.014%, SEC = 0.014%, CV = 0.80, RPD = 4.88, consistency = 101.02%), and PLS 5 for caffeine content (R2 = 0.94, SEP = 0.014%, SEC = 0.014%, CV = 0.80, RPD = 4.88, consistency = 101.02%). Keywords: Absorbance, Caffeine, Lipid, Moisture Content, Pre-Treatment.

Abstract

Objective: The study aims to determine the profile of students' critical thinking skills using E-Instruments. In this study, the profile of students' critical thinking skills, as assessed with conventional tests and E-instruments, is also compared. Method: The analysis of critical thinking skills profiles was conducted using quantitative methods. The study was conducted at a high school in East Java, Indonesia, that had used the independent curriculum. The population of this study was sampled purposively, comprising 65 students. Results: The profile of students' critical thinking skills in physics material is still relatively low. Based on the Wilcoxon test, the findings indicate that there is no significant difference between the test results obtained from conventional tests and those from E-instruments. Novelty: The novelty of this research lies in the application of E-instruments as a substitute for conventional instruments in measuring students' critical thinking skills. Its manifestation is in the implementation of point 4 of the SDGs, which aims to improve the quality of education in the field of digital technology. On the other hand, the level of students' critical thinking skills is determined by the difficulty of the material and the skill indicators that are drilled. In the future, comprehensive learning devices and models can be developed as alternatives to enhance students' skills, particularly in the use of digital technology, including media, devices, and assessment instruments, thereby increasing students' enthusiasm for learning.

Abstract

Objective : This study aims to describe the effectiveness of developing HOTS-based science and natural science textbooks in digital format within the framework of the Independent Curriculum. The Independent Curriculum provides teachers with the flexibility to design a curriculum according to the specific conditions or needs of their schools. Method: This study used the ADDIE model as the instructional design research method. The science and natural science textbooks developed in this study follow the ADDIE model, which includes the analysis stage, design stage, development stage, implementation stage, and evaluation stage. Results: The results of the study include validation and trial outcomes. The validation results of the science and natural science textbooks show an average score of 3.9, categorized as very feasible. Individual and group trials yielded average scores of 85.6 and 87, respectively, indicating the textbooks are very feasible for use based on HOTS criteria. The actual implementation of the textbooks resulted in an average score of 86.1, also classified as very feasible. Novelty: novelty in this study is the development of science and natural science textbooks that are equipped with higher-order thinking (HOTS) questions and presented in digital format. This provides convenience for both teachers and students in accessing as a reference in learning.

Abstract

Ikan lele merupakan salah satu hasil budidaya air tawar yang sangat tinggi populasinya dalam jumlah produksi yang dihasilkan. Budidaya ikan lele di Banyuwangi khususnya di kecamatan Muncar banyak dikembangkan karena cara budidaya yang sangat mudah dan permintaan masyarakat sendiri akan ikan lele yang tinggi. Cara budidaya ikan lele yang sangat mudah dan tradisional sehingga masyarakat pembudidaya kurang memperhatikan kualitas ikan yang dihasilkan. Untuk memperbaiki kualitas ikan yang dihasilkan perlu dilakukan penelitian tentang cara budidaya yang baik, salah satunya dengan menggunakan sistem budidaya bioflok. Tujuan dari penelitian ini untuk mengetahui performa ikan, kualitas air, dan efisiensi pakan. Metode yang digunakan dalam penelitian ini menggunakan metode pengumpulan data Survival Rate yang kemudian dianalisis secara deskriptif. Hasil penelitian ini menunjukkan bahwa kualitas air sistem budidaya non bioflok kurang baik yang ditunjukkan dengan tingginya kadar amonia 6-8 mg/L, sedangkan kualitas air budidaya sistem bioflok cukup baik yang ditunjukkan dengan rendahnya kadar amonia 0,25-1 mg/L. Performa ikan yang dihasilkan sistem biofloklebih cepat, ditunjukkan dengan meningkatkan nilai efisiensi pakan dan dapat menekan nilai konversi pakan, sedangkan performa ikan non bioflok kurang cepat dengan efisiensi pakan yang rendah dan tidak dapat menekan nilai konversi pakan. Sehingga budidaya sistem bioflok dengan menggunakan Probiotik Fish Megafloc dapat menghasilkan kualitas air yang baik dan pemberian pakan yang lebih efisien.

Abstract

Penanganan ikan harus dilakukan secepat mungkin untuk menghindari kemunduran mutu ikan sehingga dibutuhkan bahan dan media pendinginan yang sangat cepat dalam menurunkan suhu ikan pada pusat thermal ikan. Tujuan dilakukannya kegiatan ini yaitu untuk mengetahui bagaimana proses pasca panen yang dilakukan oleh UD. Karunia dan UD. Berkat Food sebagai penerima bahan baku hasil perikanan dari UPT. PPP Muncar. Penanganan pascapanen ikan di UD. Karunia dimulai dari penerimaan bahan baku, pencucian, penyusunan, pembekuan, penyimpanan dan pendistribusian. Sedangkan penanganan ikan di UD. Berkat Food dimulai dari penerimaan bahan baku, pencucian, penyusunan, pembekuan, dan penyimpanan. Pada kedua perusahaan tersebut yang membedakan adalah suhu pembekuan yang digunakan yaitu UD. Karunia suhunya sekitar -18oC sampai -24oC yang bertujuan menghambat pertumbuhan mikrooganisme dan aktivitas enzim di dalam produk sehingga produk menjadi lebih awet dan tidak mudah rusak dan hasilnya sangat memuaskan dan dapat bertahan selama 1 tahun. Pada UD. Berkat food suhunya sekitar -34oC sampai -40oC yang bertujuan menghambat pertumbuhan mikroganisme yang berada didalam tubuh ikan dan dapat bertahan selama 8 bulan.
