Abstract

In early January 2021, Tanjungpinang was hit by floods due to extreme rainfall intensity, causing the affected communities to suffer material and non-material losses. The flood has occurred from 2011 to 2021. To minimize the impact of flood events, it is necessary to study the characteristics of rainfall both temporally and spatially. This is considered important because with this information the public can anticipate the impact of extreme rainfall at a certain time and location. This study aims to identify the Spatio-temporal characteristics of extreme rainfall in Tanjungpinang City which often causes floods. However, to identify the characteristics of rainfall, long data is needed. This study uses CHIRPS (Climate Hazards InfraRed Precipitation with Station) satellite data because the rainfall observation data at the Raja Haji Fisabilillah station is not available for 2012. The identification results show that the correlation criterion (R) value between rainfall observation data and CHIRPS satellite data is 0.688. This value is interpreted as "strong" to be used as an alternative study data. GEE (Google Earth Engine) as a cloud-based platform is used to identify the spatial and temporal characteristics of extreme rainfall. From the results of temporal identification, it is known that extreme rainfall occurs in January, April, and December. The results of spatial identification indicate that the area that has the highest average maximum rainfalls at the Bukit Bestari District area of 156.60 mm/day. This can then be confirmed by looking at the documentation of flood events that often occur in the area.

Abstract

Petroleum is one of natural resources. Provinsi Riau is one of the petroleum producers in Indonesia. Exploitationsuch as petroleum drilling can result in pollution on the lands in the area around drilling. One method of processing contaminated oil waste that is relatively economical, easy and environmentally friendly is bioremediation. This research aims to process oil-polluted soil with bioremediationusing vermikomposting techniques. The study was conducted by varying the ratio of the weight of polluted soil with vermikompos, 1:2; 1:1; 2:1 (b/b). Observations were made over 49 days. During the study pH values, temperature, and water content were observed. The results showed the best results in reactors with a ratio ofpolluted soil and vermikompos (1:2) w/w, with an additional 20 worms with an allowance efficiency of 85.19%. pH values during observation ranged from 7-8, temperatures were 25ºC, and water levels fluctuated from 81-141%. The addition of 5% of rice husks to reactors with polluted soil composition: vermikompos (1:2) can increase the efficiency of the allowance to 90.05%.

Abstract

Pertambahan penduduk di Kota Pekanbaru yang semakin meningkat menimbulkan banyak kemacetan dibeberapa titik daerah. Salah satu titik rawan kemacetan berada pada daerah kawasan pendidikan. Kemacetan terjadi dikarenakan adanya proses antar jemput anak sekolah. Pemerintah sudah mengatasi kemacetan dengan menyediakan alat tranportasi umum yaitu bus trans metro Pekanbaru, namun hal ini belum sepenuhnya dapat mengatasi kemacetan khususnya dalam kasus antar jemput anak sekolah. Butuh rute khusus dan ketersediaan fasilitas yang sesuai dengan kenyaman, keselamatan serta ketepatan waktu bagi pelajar. Maka perlu dilakukan analisis perhitungan biaya operasional kendaraan angkutan sekolah untuk mengetahui kelayakan secara ekonomi dalam perencanaan angkutan sekolah. Hasil penelitian pada perhitungan biaya operasional kendaraan dapat menentukan tarif pada setiap rute. Besar tarif berdasarkan perhitungan BOK pada setiap rute adalah pada rute 1 sebesar Rp.7.000, rute 2 sebesar Rp.7.100, rute 3 sebesar Rp. 5.600, rute 4 sebesar Rp. 9.800, rute 5 sebesar Rp. 7.100 dan rute 6 sebesar Rp. 9.400. Nilai tarif berdasarkan BOK yang didapat menjadi bahan pertimbangan pemerintah untuk memberi subsidi penuh atau setengah dalam perencanaan angkutan sekolah di Kota Pekanbaru.

Abstract

Sampah merupakan salah satu permasalahan lingkungan hidup yang saat ini belum dapat teratasi dengan baik. Terbatasnya Tempat Pembuangan Sampah (TPA) di Kota Pekanbaru khususnya di Kelurahan Bandarraya, menjadikan permasalahan sampah ini semakin kompleks. Bank sampah menjadi salah satu pilihan dalam strategi pengelolaan sampah. Bank sampah merupakan salah satu program yang dapat mengubah cara pandang masyarakat terhadap pengelolaan sampah. Program pengabdian kepada masyarakat ini bermitra dengan DLHK Kota Pekanbaru. Beberapa permasalahan yang ada pada masyarakat, antara lain: masyarakat kurang memiliki pengetahuan tentang bahayanya sampah, kurangnya pemilahan sampah, kurangnya pengetahuan tentang bank sampah, cara kerja, serta tambahan pendapatan dengan menyetorkannya ke bank sampah. Tujuan dari kegiatan pengabdian kepada masyarakat ini ialah memberikan pengetahuan cara meminimalisir permasalahan sampah sekaligus memberi penghasilan tambahan bagi masyarakat lewat bank sampah di kelurahan Bandarraya. Metode pendekatan yang akan dilakukan berdasarkan kesepakatan dengan mitra adalah dengan sosialisasi tentang sampah dan pengelolaannya. Target luaran yang diharapkan adalah masyarakat teredukasi untuk melakukan pemilahan sampah dan menyetor ke Bank Sampah, sehingga terciptanya lingkungan yang bersih dan sehat, serta menambah pendapatan masyarakat dari pengelolaan sampah yang ada. Dukungan dari pemerintah juga sangat diperlukan untuk keberlangsungan bank sampah ini.

Abstract

Greywater is wastewater from domestic activities sourced from kitchens, bathrooms, and laundry water. Greywater discharged directly into the environment can cause a decrease in surface water quality due to its high organic content, nutrients, pathogenic bacteria, and detergents and surfactants. One method that can be used to remove organic and nutrient content is adsorption. The success of the adsorption process is determined by several factors, such as adsorbent type, dosage, contact time, and others. One adsorbent that has attracted the attention of many researchers in recent years is magnetic biochar. This study aims to remove chemical oxygen demand (COD), total suspended solids (TSS), oil, and grease from greywater with a magnetic biochar adsorbent made from palm shells. The study was conducted by varying the dose of 1.2–8.55 g/l and the contact time of 30–150 minutes. The results showed that increasing the dose and contact time can increase the removal efficiency of COD, TSS, oil, and grease. The best results were obtained at a dose of 8.55 g/l and a contact time of 150 minutes. The removal of COD, TSS, oil, and grease was 87.91%, 88.46%, and 99.96%, respectively.

Abstract

Water of river has high turbidity so it needs to be treated before being used as clean water. Common processing is coagulation, flocculation, sedimentation, and filtration. Type II sedimentation is the settling of flokulen particles, where there is an interparticle interaction so that the size increases and the rate of settling increases. This study aims to analyze the settling column in order to get isoremoval graphs of river water that have been coagulated using papaya seed biocoagulants. Isoremoval graph is useful for determining the value of surface loading rate (Vo) and time of detention (td) making it easier to design sedimentation tank. The study was conducted using a settling column with a diameter of 12.5 cm with a height of 150 cm. The operating conditions varied are sampling point depth of 25 cm, 50 cm, 75 cm, 100 cm and 125 cm with sampling time per port 10 minutes, 20 minutes, 30 minutes, 45 minutes and 60 minutes. The results showed the best turbidity of the settling column was 88.81% at a column settling depth of 25 cm with settling time of 60 minutes. The surface loading rate obtained to produce 85% deposition is 55 m3day-1m-2 with a detention time of 40 minutes.

Abstract

Pekanbaru City is the capital of Riau Province with a variety of very rapid development activities along with the increasing number of city residents, resulting in reduced vegetative land. This is the cause of the increase in surface temperature in Pekanbaru City, especially in the city center, which can accelerate the Urban Heat Island (UHI) phenomenon. The purpose of this study was to determine the distribution of surface temperature and identify the UHI phenomenon in Pekanbaru City. The research method is to identify the distribution of surface temperatures in the research period 2013-2018. Extraction of surface temperature comes from Landsat 8 imagery. The UHI phenomenon is seen from the temperature difference between the downtown area represented by Sukajadi Village and suburban areas, namely Kulim Village, Tebing Tinggi Okura, Muara Fajar, and Tuah Karya. The results showed that Pekanbaru City experienced the UHI phenomenon during the study period, because the temperature was already more than 30℃ and there was a temperature difference between the city center and the outskirts of the city that exceeded 3℃.
