Abstract

Air pollution is an unresolved environmental problem to date. Traffic density will have a direct impact on the increase of various types of exhaust emissions, one of which is sulfur dioxide (SO2). Efforts that can be made to prevent further air pollution is to monitor air quality with biomonitoring utilizing lichen as a bioindicator. This study aims to identify the type of lichen species used as bioindicators in Angsana (Pterocarpus indicus Willd.) tree stands, to analyze the correlation of traffic density with sulfur dioxide (SO2) levels in lichen thallus, to analyze the correlation of traffic density with chlorophyll levels in lichen thallus, and to analyze the correlation of sulfur dioxide (SO2) levels with chlorophyll levels in lichen thallus in Medan Industrial Area II. This research is descriptive quantitative with road sampling method on Angsana tree stands in the research location. The results showed that Lichen Lepraria incana and Drinaria picta were obtained as bioindicators in both research locations. The correlation of traffic density with sulfur dioxide levels in lichen thallus showed a very strong positive correlation between traffic density and SO₂ levels with a Pearson correlation value of 0.985 and a significance value (p-value) of 0.015. Since the p-value < 0.05, this relationship is statistically significant. The correlation of traffic density with chlorophyll levels in lichen thallus showed a strong negative correlation and was also statistically significant (p-value < 0.05) with a Pearson Correlation value of -0.958 with a significance value of 0.042. Correlation of sulfur dioxide (SO2) levels with chlorophyll levels in lichen thallus showed a strong negative correlation, but not statistically significant because the p-value> 0.05 with a Pearson Correlation value of -0.943 with a p-value of 0.057.

Abstract

Industrial areas are centers of economic activity that contribute significantly to air pollution, particularly Nitrogen Dioxide (NO₂). This research aimed to explore the relationship between traffic density, NO₂ levels, and chlorophyll content in lichen thalli on Angsana trees (Pterocarpus indicus) in Medan Industrial Area 2. This quantitative descriptive study was conducted over three months, with lichen samples collected using purposive sampling method at two locations with different traffic densities. Data collection included measurements of traffic density, environmental parameters, lichen identification, NO₂ level analysis, and chlorophyll content measurement. The results showed a very strong positive correlation between traffic density and NO₂ levels in lichen thalli, and a strong negative correlation between traffic density and total chlorophyll content. A significant negative correlation was also found between NO₂ levels and total chlorophyll content in lichen thalli. Six lichen species from five families with two different thallus types were identified on Angsana trees, showing variations in coverage area and physiological responses to pollution levels. This study concludes that lichens are effective bioindicators for detecting NO₂ pollution in industrial areas with varying traffic densities.

Abstract

Learning is a process of interaction between teachers and students that aims to achieve maximum results, but is often hampered by learning difficulties, both from internal factors such as psychology, interests, and intelligence of students, as well as external factors such as family and community environment. Initial studies at SMA St. Ignatius Medan showed that the virus material in biology lessons was one of the most difficult materials, due to its abstract nature, the use of Latin terms, and limited laboratory practice. The low cognitive achievement of students in the aspects of understanding, applying, and assessing the material indicates the need for special attention. The study aims to identify learning difficulties based on students' understanding of virus material in Class X Science at St. Ignatius Senior High School Medan, as well as the main causal factors. The research method employed is descriptive quantitative. The population includes all science classes at St. Ignatius Senior High School Medan, with the sample selected using a total sampling technique. Data collection was conducted using a two-tier multiple-choice diagnostic test and a questionnaire. The results of the study indicated that students experienced learning difficulties, with the highest rate of misconceptions occurring on the indicators of analyzing the characteristics of viruses, compiling a list of proposed preventive measures to minimize the impact of viral infections, and classifying viruses based on their genetic material along with examples. The highest rate of lack of understanding was observed on the indicators of comparing the lytic and lysogenic cycles in viral reproduction, explaining the role of viruses in life, and classifying viruses based on their genetic material along with examples. The main factors contributing to students' learning difficulties include factors related to facilities and infrastructure, particularly in the aspect of practical activities, and the intrinsic nature of virus material, especially its use of latin terminology. Abstrak. Pembelajaran merupakan proses interaksi antara guru dan siswa yang bertujuan mencapai hasil maksimal, namun sering terhambat oleh kesulitan belajar, baik yang berasal dari faktor internal seperti psikologis, minat, dan intelegensi siswa, maupun faktor eksternal seperti lingkungan keluarga dan masyarakat. Studi awal di SMA St. Ignatius Medan menunjukkan bahwa materi virus dalam pelajaran biologi menjadi salah satu materi tersulit, karena sifatnya yang abstrak, penggunaan istilah Latin, dan keterbatasan praktik laboratorium. Rendahnya capaian kognitif siswa dalam aspek memahami, menerapkan, hingga menilai materi tersebut menunjukkan perlunya perhatian khusus. Penelitian bertujuan untuk mengetahui kesulitan belajar berdasarkan pemahaman peserta didik pada materi virus kelas X IPA SMA St. Ignatius Medan dan faktor- faktor penyebab utamanya. Metode penelitian deskriptif kuantitatif. Populasi seluruh kelas IPA yang ada di SMA St. Ignatius Medan. Sampel diambil dengan teknik total sampling. Teknik pengumpulan data adalah instrumen tes diagnostik berganda dua tingkat (two-tier multiple choice) dan angket.

Abstract

Penelitian ini menelusuri makna falsafah kepemimpinan dalam budaya Minangkabau dan relevansinya bagi praktik kepemimpinan di Indonesia masa kini. Metode yang digunakan ialah pendekatan kualitatif dengan dukungan kuantitatif korelasional, melalui wawancara mendalam dan penyebaran angket kepada informan terpilih secara purposive. Analisis data dilakukan menggunakan uji korelasi Pearson untuk melihat hubungan antara tingkat pemahaman terhadap nilai-nilai kepemimpinan adat dan sikap penerapannya dalam konteks nasional. Hasil penelitian memperlihatkan bahwa pemahaman responden terhadap nilai-nilai kepemimpinan Minangkabau tergolong sangat tinggi (rata-rata skor 4,87 dari 5), sedangkan nilai korelasi r = 0,97 menunjukkan hubungan positif yang kuat antara kedua variabel tersebut. Temuan ini membuktikan bahwa semakin mendalam pemahaman seseorang terhadap nilai-nilai seperti adat basandi syarak, syarak basandi Kitabullah, bajanjang naik batanggo turun, serta duduak samo randah tagak samo tinggi, semakin bijak pula sikap kepemimpinannya. Nilai-nilai falsafah Minangkabau ini terbukti tetap relevan sebagai pedoman moral dan etis untuk membentuk karakter pemimpin yang adil, berintegritas, serta demokratis di Indonesia
