Abstract

Monitoring river water quality in Tasikmalaya Regency is an important indicator in determining IKLH (Environmental Quality Index) and the function of water for people's lives. This research was conducted to analyze the results of observations testing physical parameters (color and odor, turbidity, TDS and temperature), chemical (pH and DO/dissolved oxygen) and microbiology (total Coliform and Escherichia coli) taken from 9 river locations in the Regency Tasikmalaya using grab sampling using a descriptive qualitative approach and purposive sampling techniques. The results show that the water quality of 7 of the 9 location points still meets the water quality standards referred to in Appendix IV Government Regulation Number 22 of 2021 (Physical and Chemical Parameters) and Minister of Health Regulation Number 02 of 2023 (Microbiological Parameters). The parameters observed were odor and color with an average of odorless and 159.75 mg/L, turbidity with an average of 61.87 NTU, TDS with an average of 410.58 mg/L, temperature with an average of 27.83, pH with an average of 8.13, Dissolved Oxygen/DO with an average of 6.52 mg/L, Total Coliform with an average of 1079.88 MPN/100 mL, and Escherichia coli with an average of 1080.67 MPN/100 mL. The parameters that mostly exceed water quality standards on average at all sampling points are color, turbidity, DO (Dissolved Oxygen), TDS (Total Dissolved Solid), Total Coliform, and Escherichia coli.

Abstract

Faktor yang mendukung keberhasilan belajar seseorang diantaranya adalah faktor internal. Salah satunya berupa kemampuan seseorang untuk mengatur dan memberi arah pada dirinya sendiri sehingga mampu memperoleh hasil belajar yang maksimal. Adapun tujuan penelitian ini adalah untuk mengetahui hubungan atara self regulated learning dengan hasil belajar peserta didik pada sub konsep ekosistem di kelas XI MIPA tahun ajaran 2020/2021. Penelitian ini dilaksanakan pada bulan Agustus 2020 sampai dengan bulan September 2020 disalah satu SMAN di Kota Tasikmalaya. Metode penelitian yang digunakan adalah korelasional dengan populasi seluruh peserta didik kelas XI MIPA dengan jumlah 261 orang. sampel yang diambil dengan menggunkan teknik simple random sampling, sehingga penelitian ini mengambil sampel 7 orang dari setiap kelas XI MIPA dengan jumlah 8 kelas. Instrumen yang digunakan dalam penelitian ini terdiri dari 2 instrumen yaitu instrumen angket Motivated Strategies for Learning Questionnaire (MSLQ) bagian self regulated learning yang diadopsi dari penelitian sebelumnya dan instrumen tes yang berupa soal pilihan majemuk pada materi sub konsep ekosistem yang berjumlah 36 butir soal. Teknik analisis data yang digunakan adalah uji korelasi bivariat person dengan taraf signifikansi (É‘)=5%. Berdasarkan hasil penelitian dapat disimpulkan bahwa terdapat hubungan antara self regulated learning dengan hasil belajar peserta didik pada materi sub konsep ekosistem (R=0,502). Besar kontribusi dari self regulated learning terhadap hasil belajar sebesar 25,2%.

Abstract

The emissions of carbon dioxide (CO2) significantly contribute to the rise in global temperatures and the exacerbation of climate change. Various initiatives have been undertaken to reduce CO2 emissions, notably through the adoption of carbon capture technologies. These technologies include Carbon Capture and Utilization (CCU), Carbon Capture and Storage (CCS), and the integrated approach of Carbon Capture, Utilization, and Storage (CCUS). Our study aims to elucidate the operational principles of CCU, highlight the benefits of carbon capture, and provide recent updates on the application of CCU and CCS in daily contexts. Utilizing a qualitative descriptive methodology through a literature review, we examine the primary sources related to CCU and CCS from various databases such as Scopus, Springer, Taylor & Francis, and Google Scholar, covering the period from 2014 to 2024. As a novelty, our review covers physical techniques like absorption, gas or membrane separation, and pressure-temperature manipulation, alongside chemical methods such as the adsorption of amine compounds. Furthermore, biological techniques, including fixation, are also utilized. The operational framework of carbon capture technology is structured around three main processes: pre-combustion, post-combustion, and oxy-combustion. Notably, carbon capture technology incorporates the cultivation of microalgae as a fixation strategy, which promotes not only environmental sustainability but also shows significant promise for future applications. This method effectively sequesters large quantities of CO2 while requiring minimal nutritional resources. The advantages of utilizing microalgae include enhanced efficiency in CO2 fixation compared to terrestrial plants, reduced contamination, and a relatively simple operational structure. It is evident that the adoption of carbon capture technology is expected to increase in the coming years, particularly in light of the ongoing challenges posed by climate change. Prospective advancements in carbon capture technology are then discussed based on the review result. Thus, our literature review contributes to promoting the broader implementation of carbon capture technologies.
