Abstract

SDIT Nurul Fikri belum perna mendapat pelatihan atau sosialisai mengenai mitigasi gempa dan tsunami, termasuk informasi mengenai peningkatan bahaya akibat penguatan gelombang tsunami yang disebabkan Teluk Sungai Serut. Padahal sekolah ini berada di ujung Sungai serut. Kegiatan pengabdian ini bertujuan untuk Meningkatkan pengetahuan dan pemahaman tentang bahaya penguatan gelombang tsunami akibat amplifikasi dari refraksi gelombang Tsunami yang memasuki teluk Sungai Serut, Mensosialisaikan akses-akses berupa peta jalur evakuasi yang aman dan realistis serta mudah dijangkau pada warga sekolah SDIT Nurul Fikri. Dalam kegiatan pengabdian ini metode yang digunakan adalah metode ceramah, sosialisasi, identifikasi potensi lokal sekolah, tanya jawab dan curah pendapat (brain storming) serta pembuatan pocket book. Berdasarkan kegiatan yang sudah dilakukan menunjukan bahwa kegiatan pengabdian pada masyarakat di SDIT Nurul Fikri sudah terlaksana dengan baik. Hal ini dapat dilihat dari jumlah kehadiran peserta yang cukup banyak sesuai undangan. Tersusunya pocket book sebagai bahan bacaan khalayak sasaran dalam upaya mitigasi gempa dan tsunami. Hasil evaluasi dari kegiatan menunjukan kegiatan berjalan lancar sesuai dengan yang direncanakan, terlihat antusiasnya khalayak sasaran sebagai stake holders dalam bertanya dan diskusi. Berdasarkan hasil pre-test dan post-test terlihat terjadi peningkatan pemahaman khalayak sasaran 97% terkait pengetahuan mitigasi gempa dan tsunami.

Abstract

This study aims to conduct a field study on the need to develop Augmented Reality (AR) assisted practicum guidelines. Data collection instruments were in the form of questionnaires and interview guidelines. The subjects in this field study were students who became practicum assistants, physics laboratory staff, and lecturers of basic physics courses. Questionnaire data and interview results were analyzed qualitatively to see the real conditions of the practicum. Based on the results of data analysis, it is known that practicum manuals are still dominant in text, and practicum activities can be directed to practice problem-solving skills. The phenomenon of coastal areas can also be associated with physics practicum material. Based on the results of the practicum assistant's questionnaire, it is known that AR can facilitate physics practicum, so it is necessary to develop an AR-assisted practicum guide that presents audio-visual presentations. Based on the results of the interviews, it is also known that the constraints on practicum activities during this pandemic were that not all practicum courses were available at PheT to carry out virtual practicums, counter-dependence with assistant explanations in carrying out practicum procedures, so strict procedures could not be carried out, so it could be interpreted that a solution was needed an alternative practicum guide that is equipped with a video tutorial about practicum procedures. AR technology can be used to visualize tutorial videos that can be accessed offline.

Abstract

Pemanasan global adalah isu lingkungan yang mendesak, terutama akibat peningkatan kadar karbon dioksida (CO 2 ) di atmosfer yang memperkuat efek rumah kaca. Pemanasan global merupakan fenomena yang menjadi perhatian penting karena aktivitas manusia seperti pembakaran bahan bakar fosil dan deforestasi terus meningkatkan emisi CO 2 . Penelitian ini bertujuan untuk mengidentifikasi kadar CO 2 sebagai indikator pemanasan global dalam kurun waktu lima tahun terakhir (2019–2023). Data penelitian yang diperoleh dari Stasiun Global Atmospheric Watch (GAW) Bukit Kotatabang, meliputi CO 2 , SO 2 , NO 2 , dan suhu udara rata-rata bulanan. Data tersebut dianalisis menggunakan metode deskriptif dan kuantitatif. Hasil penelitian menunjukkan tren peningkatan kadar CO 2 selama 5 tahun (2019-2023) terutama akibat aktivitas manusia. Kadar CO 2 cenderung lebih tinggi selama musim hujan pada akhir hingga awal tahun dengan rata-rata 423,01 ppm dibandingkan saat musim panas (Mei-Juli) hanya mencapai 419,49 ppm. Gas lain seperti SO 2 dan NO 2 juga menunjukkan hal yang sama. Pada musim hujan (Jan-Feb) SO 2 meningkat mencapai rata-rata 4,79 ppb dan NO 2 mencapai 0,26 ppb. Analisis regresi menunjukkan bahwa suhu udara, SO₂, dan NO₂ memiliki pengaruh yang relatif kecil terhadap kadar CO₂, dengan koefisien determinasi masing-masing sebesar 2,66%, 2,27%, dan 3,36%. Hasil penelitian ini menyatakan bahwa peningkatan kadar CO₂ di atmosfer berkaitan erat dengan pemanasan global dan perubahan lingkungan, sehingga diperlukan upaya mitigasi untuk mengurangi emisi gas rumah kaca di Stasiun GAW Bukit Tinggi.     Kata kunci: Karbondioksida; Pemanasan Global; Stasiun GAW Bukit Kotatabang

Abstract

The Indian Ocean Dipole (IOD) is a phenomenon of ocean and atmosphere interaction characterized by differences in sea surface temperature between the eastern (90oE-110oE and 10oS-0oN) and western (50oE-70oE and 10oS-10oN) of Indian Ocean. This study examines the variability of the temperature of the Indian Ocean during the positive evolution of the Indian Ocean Dipole (IOD) in 2006. The data used in this research are Sea Surface Temperature (SST) data, wind data, monthly Sea Surface Height (SSH) data and current velocity data. zonal. These data were then analyzed using a low-pass filter with a 13-month cut-off period to observe the IOD phenomenon. The results of this study indicate that positive IOD evolution in 2006 was identified through the IOD Index, this is also supported by the results of temperature data analysis. Based on temperature data, there is a pattern of temperature differences between the eastern and western regions of the Indian Ocean. In May, the surface temperature begins to decrease, indicating the start of the IOD evolutionary phase. IOD began to occur in May with a temperature of -0.5oC. Over time, IOD evolution reaches a peak in September-October with a temperature of -1.8oC and begins to experience evolutionary decay in November-December with a temperature of -0.2oC. IOD evolution that occurs on the surface is influenced by zone currents and surface wind movements that move to the left. The positive IOD movement to the west also affects the decrease in sea level in the west coast of Sumatra which is marked by a negative value of SSHA.   Keywords: Indian Ocean Dipole, Lowpass Filter, Temperature
