Abstract

Fish product quality is crucial, and any flaws in frozen fish, such as unpleasant odor, breakage, dents, tears, or texture damage, can negatively impact its overall quality. These defects can lead to reduced customer satisfaction and adversely affect the company's brand reputation. To enhance product quality, the company must establish an efficient quality assurance system and closely monitor the handling of raw materials. The main objective of this practical work is to identify potential risks of damage and develop strategies to prevent such incidents from occurring. The Fault Tree Analysis method is utilized to systematically identify and analyze the root causes of existing errors and find appropriate solutions to address the problem. The FTA results reveal 18 basic event factors that can cause damage to fish, including worker negligence during raw goods placement, inadequate use of plastic protection, lack of rubber carpets in baskets, failure to adjust freezing temperature properly, insufficient inspections, non-compliance with Standard Operating Procedures, improper fish arrangement, excessively hard freezing temperature, employee laziness and carelessness, absence of basket mats, prolonged freezing step, unset temperature checks, mishandling of raw goods due to a rush to finish quickly, and irregular temperature checking schedules. The study aims to understand the step-by-step process of handling flying catfish, identify the factors contributing to fish damage, and analyze the potential damage scenarios.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan media Geoboard terhadap pemahaman konsep bangun datar pada siswa kelas IV sekolah dasar semester genap tahun ajaran 2024/2025. Penelitian menggunakan metode quasi eksperimen dengan desain Nonequivalent Posttest-Only Control Group. Sampel penelitian terdiri atas 28 siswa kelas IV C sebagai kelompok eksperimen yang belajar menggunakan media Geoboard dan 25 siswa kelas IV A sebagai kelompok kontrol yang belajar menggunakan media PowerPoint, yang dipilih melalui teknik purposive sampling. Instrumen penelitian berupa tes esai berjumlah 8 soal untuk mengukur pemahaman konsep siswa. Hasil analisis menggunakan uji t menunjukkan adanya perbedaan signifikan antara kelompok eksperimen dan kontrol. Dengan demikian, penggunaan media Geoboard terbukti efektif dalam meningkatkan pemahaman konsep bangun datar siswa sekolah dasar.

Abstract

This research aims to determine the influence of government investment and expenditure and local revenue in the province of North Sumatra. The data used in this research uses the multiple linear regression analysis method using the E-views 10 program. The partial research results show that the investment variable has a negative and significant effect on local revenue, the government expenditure variable has a positive and significant effect on local revenue, research results Simultaneously, investment and government expenditure variables have a significant effect on local original income. The Determination Coefficient (R2) is 0.667388. This means that the magnitude of the influence of investment variables and government expenditure on the local income of North Sumatra Province is 0.6674 (66.74%) while that which is influenced by other variables outside this research model is 0.3326 (33.26%).

Abstract

This research is motivated by students' science process skills which are still in the low category. Based on the initial observations made there were students who still had difficulty in conducting experiments. This research aims to determine the increase in the ability to observe, identify and define variables through the comic-assisted inquiry learning model. This research was conducted on class XI MIPA 2 students at SMAN 2 Banda Aceh involving 32 students. The research design used in this study isone grup pretest-posttest design. Data collection techniques through tests (pretest andposttest) and student response. The pretest and posttest questions in this research were prepared referring to three indicators of science process skills, namely, observing, identifying and defining variables. After the data is collected, the data is analyzed using the gain test. The results of the research showed that there was an increase in students' science process skills in the aspect of observing by 0.54 in the medium category, identifying by 0.68 in the medium category and defining variables by 0.72 in the high category. Based on the results of this research, it can be concluded that the ability to observe, identify and define variables can be improved through comic-assisted inquiry learning

Abstract

Permasalahan utama yang dihadapi adalah rendahnya kapabilitas guru mengenai Education for Sustainable Development (ESD), keterbatasan perangkat ajar berbasis keberlanjutan, dan minimnya keterampilan praktis lingkungan pada guru sekolah dasar. Oleh karena itu, dilakukan kegiatan pengabdian yang bertujuan untuk meningkatkan kapabilitas guru sekolah dasar dalam merancang dan mengimplementasikan pembelajaran berbasis Sustainable Project yang berakar pada prinsip ESD. Implementasi Green School juga bertujuan untuk membangun budaya sekolah yang peduli lingkungan melalui aktivitas pengelolaan limbah, penghijauan, hemat energi, da pemanfaatan teknologi ramah lingkungan. Metode pengabdian dilakukan melalui kegiatan sosialisasi, pelatihan, penerapan teknologi, dan pendampingan penyusunan perangkat pembelajaran IPA berbasis ESD. Hasil evaluasi menunjukkan peningkatan signifikan pada empat indikator utama, yaitu pemahaman konsep ESD, perancangan perangkat ajar, keterampilan praktis lingkungan, serta kolaborasi guru dalam komunitas KKG, dengan rata-rata capaian akhir di atas 90%. Program ini terbukti efektif meningkatkan kompetensi konseptual, pedagogis, dan praktis guru, sekaligus mendorong inisiatif Green School yang berkelanjutan dan dapat direplikasi di sekolah dasar lainnya.
