Penetapan tarif air minum PDAM Kampar diatur dalam Peraturan Daerah Kabupaten Kampar Nomor 19 tahun 2009, tentang Pelayanan Air Minum PDAM Tirta Kampar dan Peraturan Bupati Kampar Nomor 54 tahun 2014 tanggal 29 Desember 2014, tentang Tarif Air Minum PDAM Kampar. Namun, kesediaan membayar akan mencerminkan persepsi masyarakat terhadap keberadaan dan pentingnya air bagi masyarakat. Selain itu, penetapan/ kenaikan tarif harus selalu disesuaikan dengan kualitas pelayanan yang nyata bagi konsumen. Analisis willingness to pay (WTP) bertujuan untuk mengetahui kesanggupan untuk membayar biaya pelayanan pengadaan air bersih (PDAM) untuk Kecamatan Salo Kabupaten Kampar. Pengolahan dan analisis data dilakukan dengan bantuan program Statitical Product and Service Solutions (SPSS) untuk 100 sampel masyarakat pengguna layanan PDAM Tirta Kampar di Kecamatan Salo. Analisis data yang akan digunakan yaitu analisis regresi linier sederhana dan berganda, pengujian asumsi klasik dan juga analisis reliabilitas. Hasil analisis survei menunjukkan porsi dominan masyarakat mau membayar Willingness to Pay berada dalam range Rp. 40.000 – Rp. 60.000 sebanyak 47 orang atau 47% dari jumlah rumah tangga yang diteliti. Faktor korelasi yang relatif kuat dalam mempengaruhi nilai kesediaan terletak pada Jumlah anggota keluarga dan pendapatan rata rata. Tarif air berdasarkan rata-rata kesediaan masyarakat bersedia membayar air (Willingness to Pay) sebesar 2.626,39/m3. Tarif air ini lebih rendah dari tarif PDAM pada saat itu yaitu sebesar Rp. 3.500,00/m3. Perbedaan tarif persepsi masyarakat dan PDAM diharapkan dapat memacu PDAM untuk meningkatkan kualitas dan kuantitas pelayanan agar persepsi masyarakat akan tarif yang diharapkan sesuai dengan yang ditetapkan PDAM.

Flooding remains one of the most common hydrometeorological disasters in Indonesia, primarily caused by reduced soil infiltration capacity, vegetation degradation, and low environmental awareness. Addressing this problem requires an integrative mitigation strategy that combines technical solutions with community-based education. This study presents a community service program aimed at improving students' environmental awareness and practical skills in flood prevention through tree planting and biopore infiltration holes at SMPN 25 Pekanbaru. The program adopted a participatory approach, including educational sessions, demonstrations, and hands-on activities. The results showed a significant increase in student knowledge, with the average score increasing from 43.6% in the pre-test to 88.4% in the post-test, representing a relative increase of 105.6%. The highest increase was observed in understanding the concept of biopores, which increased by 148.6%. Furthermore, students demonstrated increased engagement and active participation in environmental conservation practices.The uniqueness of this study lies in the integration of a simple ecotechnological solution, a biopore infiltration system, with experiential learning at the junior high school level, providing both immediate educational outcomes and long-term environmental benefits. This approach not only increases infiltration capacity and reduces surface runoff but also supports sustainable organic waste management and ecological awareness. Therefore, the proposed model can serve as an effective and applicable strategy for flood mitigation education in school-based community programs.

Penelitian ini bertujuan merumuskan strategi optimasi desain struktur sistem ganda pada gedung bertingkat melalui pemanfaatan analisis modal eigen sebagai dasar pengambilan keputusan desain. Prinsip utama strategi optimasi ini adalah memastikan mode translasi arah Ux atau Uy pada Mode 1 dan Mode 2 memiliki partisipasi massa lebih dari 60%, sehingga respons dinamik struktur didominasi oleh gerakan translasi dan menghasilkan perilaku yang lebih stabil terhadap beban gempa. Metodologi penelitian meliputi identifikasi dan pemodelan struktur eksisting sebagai studi kasus, pengumpulan data desain, analisis respons struktur, serta evaluasi kinerja berdasarkan SNI 1726:2019, SNI 1727:2020, dan SNI 2847:2019. Selanjutnya dilakukan penyusunan model desain alternatif melalui redesain elemen struktural sesuai ketentuan optimasi. Analisis dilakukan menggunakan perangkat lunak ETABS v21 dengan memanfaatkan fitur Auto Select dan iterasi otomatis untuk memperoleh penampang dan mutu material paling efisien. Hasil penelitian menunjukkan bahwa strategi optimasi mampu meningkatkan performa struktur sekaligus memberikan efisiensi konstruksi. Pada desain eksisting ditemukan partisipasi torsi yang cukup besar serta lima balok beton mengalami overstress akibat kombinasi beban seismik. Model alternatif menghasilkan penurunan signifikan partisipasi torsi pada mode translasi, dari 25,5% menjadi 0,47% pada Mode 1 dan dari 26,7% menjadi 0,5% pada Mode 2. Seluruh overstress pada elemen beton berhasil dieliminasi, kontrol simpangan antar tingkat tetap berada di bawah batas izin, dan persyaratan sistem ganda tetap terpenuhi. Selain itu, mutu beton dapat direduksi dari f’c 35 MPa menjadi f’c 30 MPa, serta berat struktur menurun dari 13.984.498,48 kg menjadi 9.921.432,47 kg
