Pemanfaatan Eco Enzyme Dalam Meningkatkan Kualitas Air Sungai Siak Kota Pekanbaru
This study aimed to analyze the effect of eco-enzyme addition on the water quality of the Siak River in Pekanbaru City. An experimental method was applied at three sampling locations using eco-enzyme concentrations of 0%, 2.5%, 5%, and 7.5% with a five-day incubation period. Water quality parameters measured included pH, dissolved oxygen (DO), biological oxygen demand (BOD), total dissolved solids (TDS), and color. The results indicated that eco-enzyme application reduced pH and DO values while increasing BOD, TDS, and color due to enhanced biodegradation of organic matter. The optimal eco-enzyme concentration ranged between 2.5% and 5%, which effectively promoted decomposition processes without causing excessive deterioration of water quality. These findings demonstrate that eco-enzyme has potential as a natural bioremediation agent for improving river water quality.

The objectives of this study are: (1) to estimate the economic value of ecotourism in Bandar Bakau, and (2) to analyze the factors influencing mangrove ecotourism visits. This research employed a descriptive qualitative and quantitative approach using a survey method. Data were collected through accidental sampling from visitors to the Bandar Bakau mangrove ecotourism site. Information was obtained through questionnaires, interviews, and observations, and analyzed using regression to derive the demand curve and consumer surplus. The estimated consumer surplus value in Bandar Bakau is IDR 363,552 per visitor per trip. Based on the consumer surplus and total number of visits, the total economic value of Bandar Bakau was calculated at IDR 5,357,866,140. The factors that significantly influence the number of visits include travel costs, age, income, education, occupation, and length of visit, all of which have a significant simultaneous effect. However, partially, only the travel cost factor has a highly significant effect on the number of visits, while other factors have no significant influence.
Pengaruh Media Tanam Terhadap Pertumbuhan Bibit Bakau Minyak (Rhizophora apiculata Bl.)
Mangrove ecosystems have an important role to play in maintaining coastal ecological balance, but high levels of damage require effective rehabilitation efforts. One of the main species that is widely used in rehabilitation is Rhizophora apiculata Bl., as it has strong roots, high tolerance to tides, and a relatively fast growth rate. The success of rehabilitation is highly dependent on the quality of the seedlings planted, while the planting medium in the seedbed is a key factor that determines early growth. This study aims to evaluate the influence of various types of planting media on the growth of R. apiculata seedlings. The experiment was carried out with a complete random design using several media treatments, including M1 (Ultisol soil media), M2 (peat soil media), M3 (sea mud soil media) and M4 (river sand media), each repeated four times. The observed parameters included propagule survival percentage, height gain, diameter increase, number of leaf blades and longest root length. The results showed that the planting medium provided 100% live propagule, significantly affecting the parameters of increase in height, number of leaf strands, and longest root length, but not significantly affecting the parameters of increase in propagule diameter. The best planting medium is M3 (Sea mud soil media). These findings affirm the importance of selecting appropriate planting media to improve the quality of seedlings in the seedbed phase, so that it can be a practical reference in nursery activities and mangrove rehabilitation programs, as well as making a scientific contribution to the development of sustainable mangrove silviculture.

Nilai Uji Rendam (Immersion Test) Dari Material Recycle Asphalt Pavement (RAP) Dengan Menambahkan Oli Bekas Pada Perkerasan Jalan
Reclaimed Asphalt Pavement (RAP) is the result of dredging the old road pavement which is usually used as backfill and has even become waste that is usually rarely used. RAP material that is no longer used can be used as an additive in the manufacture of new asphalt concrete with rejuvenator. This study aims to determine the durability of used motor vehicle oil as a rejuvenating agent for RAP on the Lataston mixture gradation (HRS-WC) on Marshall and IRS characteristics. The testing stage is to test the characteristics of the RAP material. The optimum asphalt content (KAO) for the aggregate was obtained at 7,24%, while the optimum used oil content was obtained at 4,94% by weight of asphalt as a RAP rejuvenator. Marshall and IRS characteristics testing are in accordance with the 2018 Highways specification. Marshall test results show that as the amount of used oil freshener is added, the ability of the mixture to withstand loads decreases and the flexibility of the mixture increases, resulting in reduced asphalt durability represented by testing IRS 30 minutes and 24 hours which showed the durability value obtained a value of 60,49% in the Lataston mixture. As a result, the IRS value does not meet the requirements of the 2018 Highways Specification of 90%, so it is concluded that the results of the tests carried out do not meet the durability requirements and cannot be applied in the field..

Studi Eksperimental Campuran AC – WC Menggunakan Aspal Modifikasi Karet Alam Dengan Variasi Suhu Pemadatan Terhadap Nilai Durabilitas
Changes in asphalt temperature can cause deformation damage and cracks in the asphalt so that the appropriate temperature is needed to prevent damage in the field. Durability is the resistance of asphalt to changes in temperature, weather, water and air, asphalt with poor durability will cause the asphalt surface to be easily damaged and the surface can deform so that the asphalt becomes bumpy and endangers driving activities, poor durability also results in reduced road plan life. This study aims to determine the durability value of natural rubber asphalt using compaction temperature variations of 100 ℃, 100 ℃, 110 ℃, 120 ℃, 130 ℃ and 140 ℃. The research started with the examination of aggregate properties and asphalt properties then continued with making test specimens to determine the optimum asphalt content with variations of 5%, 5.5%, 6%, 6.5%, 7% obtained optimum asphalt content of 6.38%. Next, make test specimens with variations in compaction temperature of 100 ℃, 110 ℃, 120 ℃, 130 ℃ and 140 ℃. After the specimens are made based on the compaction temperature variation, durability testing is carried out for 30 minutes and 24 hours in a waterbath tool using a temperature of 60 ℃. From this test, the durability value is obtained at 100 ° C durability value 116%, 110 ° C durability value 103%, 120 ° C durability value 93%, 130 ° C durability value 85%, 140 ° C durability value 80%.
