Sekitar 60% bencana alam ialah bencana alam akibat dari kejadian iklim ekstrem seperti banjir, kekeringan, kebakaran hutan, angin kencang/badai, tanah longsor, gelombang pasang tinggi dan meledaknya penyakit. Perubahan iklim menyebabkan meningkatnya ancaman terhadap ketahanan pangan, kesehatan manusia, ketersediaan air, dan juga ancaman keragaman hayati. Sebanyak 23 dari 323 kabupaten/kota di Indonesia rentan terhadap perubahan iklim yang dikarakterisasi sebagai tingginya nilai rasio rendaman, nilai kepadatan penduduk, nilai kawasan permukiman dan nilai kawasan non permukiman. Kota Pekanbaru mengalami perubahan iklim yang berdampak cukup nyata terhadap masyarakat Pekanbaru. Tujuan dari penelitian ini untuk mengetahui tingkat kerentanan Kota Pekanbaru terhadap perubahan iklim. Metode yang digunakan untuk mengetahui tingkat kerentanan yaitu metode Centre for Climate Risk and Opportunity management (CCROM). Software Arc Gis 9.3 untuk memperoleh peta tingkat kerentanan Kota Pekanbaru. Analisis data dilakukan secara deskriptif. Hasil dari perhitungan tingkat kerentanan bahwa terdapat 49 kelurahan di Kota Pekanbaru tidak kategori rentan, 6 kelurahan dalam kategori agak rentan yaitu Kelurahan Kampung Tengah, Rejosari, dan Sukajadi, Industri Tenayan, Limapuluh dan Tanjung Rhu. Daerah yang dalam kategori rentan hanya satu yaitu Kelurahan Meranti Pandak.

The need for predictions is very necessary in various sectors of life, one of which is rainfall predictions. The threshold value for PM10 particles that is allowed to be in ambient air is, 150 µgram/m3/day). The aim of this research is to create a dynamic model predicting Pekanbaru City's rainfall for the next 3 years. Rainfall prediction in this research was carried out using the dynamic system modeling method with Powersim software. The data used is BMKG data for the Pekanbaru City for 5 years (2015 – 2019) using 4 parameters, namely rainfall, air humidity, wind speed and temperature. Prediction results show that air humidity in Pekanbaru City has the same pattern as BMKG, namely the highest month is December and the lowest is August. Wind speed prediction results are highest in July and lowest in May. The highest temperature in Pekanbaru City is in April and the lowest is in January. Rainfall for 2020 – 2021 is predicted to experience light rain on average, because it has the same data pattern on the variables that influence it. So it can be interpreted that the validation results for air humidity, wind speed and temperature in Pekanbaru City show that they are valid because they do not exceed the limit value of ≤ 5%.

This research was conducted in March 2022 in the Coastal Waters of Dumai City. This study aims to analyze the amount of organic matter and the abundance of macrozoobenthos and the relationship between the amount of organic matter and the abundance of macrozoobenthos. The method used is a survey method consisting of 10 stations with 2 replications at each station. And 1 station is a control station located on the north coast of North Rupat District, Bengkalis Regency. Sediment sampling was carried out in the field and then taken to the Marine Chemistry Laboratory, Riau University for analysis of organic matter and macrozoobenthos analysis. Based on a simple linear regression test, the relationship between the amount of organic matter and the abundance of macrozoobenthos obtained a correlation value (r) = -0. 4637 with the mathematical equation y = -4.884x + 98.896. The test results show a weak and inverse relationship between the amount of organic matter and the abundance of macrozoobenthos. This means that with the increase in the amount of organic matter, the abundance of macrozoobenthos in the coastal waters of Dumai City will decrease. The value of the coefficient of determination (R2) is 0.2146. This figure shows that the

AbstrakAmerican Hospital Association menyatakan bahwa rumah sakit adalah lembaga yang mencakup tenaga medis profesional dan fasilitas kesehatan tetap yang mengelola berbagai layanan kesehatan, termasuk pemeriksaan, diagnosis, dan pengobatan. Aktifitas rumah sakit berpotensi menghasilkan limbah cair, padat, dan gas. Tujuan dari penelitian ini adalah mengevaluasi hubungan antara aktivitas rumah sakit dan karakteristik pH, suhu, serta COD dalam limbah yang dihasilkan. Pendekatan yang digunakan dalam penelitian ini adalah observasional analitik secara deskriptif, menggunakan uji korelasi Pearson untuk menganalisis hubungan antara variabel-variabel tersebut. Hasil penelitian menunjukkan bahwa pH memiliki hubungan signifikan dengan jumlah pasien rawat inap (r = -0,840, p = 0,018). Karakteristik suhu tidak menunjukkan hubungan signifikan dengan variabel lain, sementara COD menunjukkan hubungan signifikan dengan jumlah karyawan (r = -0,905, p = 0,005), yang berarti peningkatan jumlah karyawan berkorelasi dengan penurunan COD. Kata Kunci : air limbah rumah sakit, korelasi , pH, suhu, COD AbstractThe American Hospital Association defines hospitals as institutions comprising medical professionals and fixed health facilities that manage various health services, including examination, diagnosis, and treatment. Hospital operations have the potential to generate liquid, solid, and gaseous waste. This study aimed to evaluate the relationship between hospital activities and pH, temperature, and COD characteristics in the waste produced. The research employed a descriptive-analytical observational approach, utilizing the Pearson correlation test to analyze the relationships between these variables. The findings revealed that pH had a significant relationship with the number of inpatients (r = -0.840, p = 0.018). Temperature characteristics showed no significant relationship with other variables. Meanwhile, COD demonstrated a significant relationship with the number of employees (r = -0.905, p = 0.005), indicating that an employee increase correlates with decreased COD levels.

The environmental challenges faced by Batik Bujang and Batik Candafa, two Riau-based SMEs, stem primarily from the production process, which generates substantial wastewater containing harmful chemicals. The improper disposal of these by-products poses serious risks to water bodies and surrounding ecosystems. This research aims to design a waste management system using eco-friendly technologies capable of processing up to 40 liters of wastewater, thereby minimizing environmental harm. A mixed-method approach was adopted, combining quantitative analysis of waste volume and chemical composition with qualitative insights from SME owners. The findings indicate a significant reduction in chemical pollutants post-treatment, aligning with eco-sustainability goals. This study fills the research gap by providing a technological solution specifically tailored to the needs of small-scale batik producers, emphasizing sustainability and environmental responsibility.

Pengolahan air limbah dari bengkel kendaraan bermotor merupakan tantangan lingkungan yang signifikan karena tingginya kandungan bahan organik, termasuk Total Organic Carbon (TOC). Salah satu solusi yang inovatif dan efisien adalah penggunaan metode elektrokoagulasi. Penelitian ini bertujuan untuk mendesain alat elektrokoagulasi yang portabel dan menentukan waktu yang efisien untuk penurunan parameter TOC. Dalam penelitian ini, elektroda aluminium digunakan untuk menginduksi reaksi elektrokimia, menghasilkan ion logam yang mampu mengadsorpsi dan mengendapkan kontaminan dalam air limbah bengkel.Eksperimen dilakukan dengan variasi waktu proses elektrokoagulasi, yaitu 3 jam dan 5 jam, untuk mengukur efisiensi penurunan TOC. Hasil uji laboratorium menunjukkan bahwa proses elektrokoagulasi selama 3 jam berhasil menurunkan kadar TOC sebesar 55,7%, sementara proses selama 5 jam mencapai efisiensi 86,4%. Proses ini efektif dalam mencapai standar baku mutu yang ditetapkan untuk TOC, yaitu 110 ppm.Keunggulan elektrokoagulasi terletak pada efisiensi yang tinggi, biaya operasi yang lebih rendah, serta tidak memerlukan penambahan bahan kimia, sehingga menjadi solusi yang potensial untuk pengolahan air limbah dari bengkel. Penelitian ini memberikan kontribusi dalam bentuk desain inovatif yang dapat diaplikasikan pada skala kecil, khususnya bagi bengkel kendaraan bermotor yang membutuhkan teknologi pengolahan air limbah yang efektif dan ekonomis.
