Analisis Dinamika Faktor Lingkungan Selama Proses Pengkristalan Garam di Greenhouse Salt Tunnel (Studi kasus di Pantai Utara dan Pantai Selatan, Jawat Timur, Indonesia)
No full textSalt is an essential commodity for both domestic use and industrial applications, with East Java Province in Indonesia playing a crucial role in national salt production. Traditional salt production methods, primarily based on natural evaporation, face challenges due to seasonal factors, particularly during the rainy season. This study investigates the environmental conditions affecting the salt crystallization process in the Greenhouse Salt Tunnel (GST) technology. Field experiments were conducted at two sites, Tuban Regency on the North Coast and Malang Regency on the South Coast, where key parameters such as air temperature, water temperature, humidity, wind speed, and evaporation rates were monitored three times daily. The findings showed that water temperatures within the GST ranged from 31 to 38°C on the North Coast and 26 to 38°C on the South Coast. Wind speeds varied between 1.5–2.4 m/s on the North Coast and 0.4–1.0 m/s on the South Coast, while humidity levels ranged from 54 to 80%. The GST system achieved a salt production rate of 6.4 kg/m² with NaCl content exceeding 94%, a significant improvement over traditional methods, which yield less than 70% NaCl. These results demonstrate that GST technology enhances both the quality and quantity of salt production, though design modifications are needed to address the dynamic coastal environment.Garam merupakan komoditas strategis yang sangat penting baik dalam konsumsi sehari-hari maupun dalam industri. Provinsi Jawa Timur, Indonesia, merupakan pemain kunci dalam lanskap produksi garam nasional. Selain Pulau Madura, lokasi produksi garam di Jawa Timur terletak di sepanjang Pantai Selatan dan Utara. Wilayah pesisir ini menunjukkan ciri-ciri geografis yang khas – Pesisir Utara dicirikan oleh tanah berpasir atau tanah liat berpasir yang padat, yang umumnya dipilih untuk produksi garam, sedangkan Pesisir Selatan memiliki pantai berpasir yang luas. Selain itu, air laut, yang merupakan bahan baku utama produksi garam, memiliki kualitas yang relatif murni. Proses produksi garam di Indonesia sebagian besar mengandalkan metode evaporasi yang terhenti pada musim hujan. Oleh karena itu, memperkenalkan pendekatan inovatif untuk mengoptimalkan laju penguapan, seperti Terowongan Garam Rumah Kaca (GST), menjadi hal yang sangat penting. Penerapan teknologi ini bergantung pada parameter lingkungan dalam GST. Penelitian ini bertujuan untuk mengkaji dinamika lingkungan selama proses kristalisasi garam dalam kerangka GST. Dilakukan di dua kabupaten yang mewakili, Kabupaten Tuban di Pesisir Utara dan Kabupaten Malang di Pesisir Selatan, penelitian ini mengungkap kondisi lingkungan yang sebanding dalam GST selama uji lapangan. Dinamika suhu udara, suhu air, dan kelembaban udara di Pesisir Selatan dan Utara Jawa Timur menunjukkan disparitas yang minimal. Namun, perbedaan mencolok muncul dalam kecepatan angin di antara wilayah pesisir ini. Penelitian ini menyimpulkan bahwa dinamika kecepatan angin di Pesisir Selatan menunjukkan fluktuasi yang cukup besar, sehingga memerlukan desain GST khusus yang mampu memitigasi kondisi ini untuk mempertahankan tingkat penguapan yang optimal. Temuan ini memberikan wawasan berharga bagi kemajuan teknologi produksi garam, terutama di lingkungan yang dinamis seperti Pantai Selatan selama musim yang berbeda

Review of Relevant Literature About Critical Thinking Skills in a Science Perspective
No full textCritical Thinking (CR) is one of the most important thinking skills and is a widely recognized measure of the quality of student learning. The literature reviewed shows the importance of integrating critical thinking (CR) into curriculum content and teaching methods in a tiered manner. This study uses the Systematic Literature Review (SLR) method, to map where CT is taught, which countries have research trends on CT, how to teach and assess CT, and the influence of technology on CT. Documents were analyzed comprehensively in the Scopus database for the 2018-2023 period. There are five stages of SLR research, namely determining keywords, searching for data, selecting documents, validating data, and analyzing data. Only documents in the form of articles published in the journals used were analyzed. The results of the study indicate that critical thinking skills must be taught and trained at the school level, both in elementary schools, secondary schools, and in certain courses. CT teaching is carried out by choosing the right model or strategy, for example using a modified inquiry model or STEM approach strategy. Assessment is carried out using instruments such as critical thinking skills tests or observation rubrics that have been standardized or modified to obtain accurate results
Standardizing Catch Per Unit Effort (CPUE) of Coryphaena hippurus in the Southern Java Waters Using Generalized Additive Model (GAM)
No full text: Improving catch data through the standardization of catch per unit effort (CPUE) is crucial in providing accurate information for fish stock assessments. This study aims to develop a CPUE standardization model for dolphinfish (Coryphaena hippurus) in the Southern Java Waters. The analysis is based on historical dolphinfish catch data collected between 2019 and 2023. Bias in the CPUE data was reduced using the generalized additive model (GAM) approach. The results indicate that all explanatory variables significantly influence CPUE standardization. The combination of fishing duration, location, and period parameters proved effective in standardizing CPUE. The GAM-based standardization method successfully reduced variability in nominal CPUE, producing more consistent data. These results can provide an essential scientific basis for developing a sustainable management strategy for the Indian Ocean dolphinfish
Smartphone Sensor-Based Physics Module for Hands-On Learning in Waves and Optics
