Abstract

Guppy fish (Poecilia reticulata) inhabit polluted water, such as domestic waste-filled ditches in residential areas, as well as in rivers. These two habitats have different water qualities, which affects the growth of the fish; this is reflected in the pattern of growth rings in the otoliths. To determine the differences in growth ring patterns of otoliths in guppies living in ditches versus the river, a study was conducted in March and April 2025. Fish were caught using a scoop net once every 2 weeks, three times. The fish were measured, and otoliths were taken. They were then attached to objects made of glass and manually shaved using a smooth grindstone. The growth rings in the otolith were observed using a microscope. Results showed that 103 fish were caught, 50 from the trench and 53 from Tangkerang River. The size of the fish caught was 18-31 mm from the trench and 17-31 mm from the river. In fish with the same total length, the otoliths from the river were longer and wider (0.5-1 mm in length and 0.4-0.95 mm in width), whereas those from the trench were shorter (0.42-0.85 mm in length and 0.4-0.67 mm in width). The maximum number of dark rings on the otoliths of fish from the ditch was 3, whereas from the river, it was 4. There were 27 fish from the river and 18 fish from the trench that had no dark ring in the otolith. The data obtained show that the growth of guppies in the Tangkerang River is better than in the Purigiam Housing trench

Abstract

Penelitian yang dilakukan pada petani kelapa sawit di Desa Pauh, Kecamatan Bonai Darussallam, Kabupaten Rokan Hulu, Riau ini ini bertujuan untuk mengetahui biaya produksi, penerimaan, pendapatan dan rasio penerimaan dan biaya pada petani kelapa sawit yang menggunakan pupuk organik Liboganik. Penelitian dilaksanakan dari Januari hingga Maret 2024. Jumlah sampel sebanyak 63 diambil dari populasi 102 dan teknik pengambilan sampel yang digunakan adalah metode random sampling. Penelitian ini mengumpulkan data primer dan sekunder. Analisis data dilakukan untuk menghitung biaya, penerimaan, pendapatan, dan R/C ratio. Hasil penelitian menunjukkan rata-rata biaya produksi untuk usahatani kelapa sawit sebesar Rp 1.992.063 /bulan/ha dengan pendapatan kotor sebesar Rp 5,719,048 /bulan/ha. Rata-rata pendapatan bersih usahatani kelapa sawit sebesar Rp 3.726.984 / bulan / ha. Usahatani kelapa sawit di Desa Pauh, Kecamatan Bonai Darusallam secara ekonomi menguntungkan berdasarkan nilai rasio R/C sebesar 2,87 atau lebih besar dari 1. Hal ini berarti bahwa untuk setiap tambahan Rp1.000,00 biaya yang dikeluarkan oleh petani akan menghasilkan pendapatan sebesar Rp2.870,00. Upaya meningkatkan ekonomi usahatani dapat dilakukan melalui penghematan biaya dengan membeli pupuk organik yang lebih murah, penggunaan pupuk organik Liboganik khusus lahan gambut, menghindari penggunakan pupuk kimia, peningkatan SDM dan pembukaan kantor distribusi di wilayah yang dekat dengan petani seperti di Taluk Kuantan dan Medan.

Abstract

This study was designed to analyze and examined the environmental management strategy of Liboganik solid organic fertilizer factory derived from solid palm oil waste in Pauh Village, Bonai Darussalam District, Rokan Hulu Regency, Riau. The study used a qualitative approach method using questionnaire and interview instruments as well as laboratory tests conducted with samples of company leader, factory employees, communities around the fertilizer factory and palm oil farmers totaling 63 and selected randomly. The results of the study showed that the water quality of the Liboganik organic fertilizer factory waste was polluted, as seen from the data from the physical parameter laboratory tests above, it can be seen that the suspended solids (TSS) content and COD content exceed the standard COD waste standards for organic fertilizer factories according to the standard of the Minister of Environment Regulation No. 5 of 2014 concerning Wastewater Quality Standards. Environmental management can be carried out through the spatial planning of fertilizer factory buildings as well as through the construction of adequate infrastructure and paying attention to its impact on the environment and factory workers in order to encourage the realization of an environmentally friendly fertilizer factory. It is concluded that environmental management of organic fertilizer factories can be done by making a ditch pond to accommodate seepage of residual palm oil factory waste and limiting it so that pollution does not occur to the community environment. In addition, in an effort to reduce high COD and BOD content, wastewater management can be carried out using Phytoremediation techniques and also technology using Vertical Water Circulation (SAV). The results of IFAS and EFAS as well as SWOT analysis concluded that the environmental management strategy of the Liboganik organic fertilizer factory is in the SO quadrant and is included in Aggressive Strategy.

Abstract

Ikan baung (Hemibagrus nemurus) merupakan salah satu ikan air tawar unggulan yang banyak digemari masyarakat karena rasanya yang gurih, kandungan protein tinggi, dan nilai ekonominya yang baik. Namun, dalam kegiatan pembenihan sering dijumpai kendala pada tahap larva, yaitu pertumbuhan yang lambat dan tingkat kelangsungan hidup yang rendah. Metode budidaya ikan baung untuk meningkatkan pertumbuhan dan survival larva dapat dilakukan melalui perendaman larva menggunakan probiotik. Probiotik dipilih karena mudah diaplikasikan, ramah lingkungan, dan mengandung mikroorganisme yang berfungsi memperbaiki sistem pencernaan serta meningkatkan daya tahan tubuh larva. Penerapan teknologi perendaman probiotik menghasilkan pertumbuhan larva yang lebih cepat, tingkat kelulushidupan lebih tinggi, serta benih yang lebih sehat dibandingkan dengan larva tanpa perlakuan.

Abstract

The Slaughterhouse (RPH) plays a vital role in supporting food security and the regional economy. However, if not properly managed, it can have significant environmental impacts. This study aims to analyze the management of the Bangkinang Slaughterhouse in Kampar Regency and evaluate its environmental impact. The methods used include field surveys, observations, interviews with relevant stakeholders, and wastewater quality analysis using the grab sampling method. The results show that while the management of the Bangkinang Slaughterhouse complies with most of the requirements of the Minister of Agriculture Regulation No. 13/Permentan/OT.140/1/2010, the Wastewater Treatment Plant (IPAL) facilities are not functioning optimally. Measurements of wastewater quality revealed that COD and BOD levels exceed the allowable thresholds, posing a risk of environmental pollution. This condition requires improvements in waste management to prevent negative impacts on the ecosystem. Furthermore, public perception of the slaughterhouse tends to be negative due to the limited social benefits, although negative effects such as odor and health disturbances are still within a non-disruptive category. This study recommends the optimization of the IPAL system and enhancement of supporting facilities to ensure better and more environmentally friendly waste management

Abstract

This study aims to evaluate the sustainability level of management of the Kepau Jaya Special Purpose Forest Area (KHDTK) in Kampar Regency, Riau Province, based on four main dimensions: ecological, economic, socio-cultural, and legal and institutional. The analytical method used was Multidimensional Scaling (MDS) with the Rap-SPFA tool, which was modified to assess multidimensional sustainability status. The analysis was conducted by measuring the sustainability index of each dimension using a scale of 0-100. The results showed that the overall level of sustainability was in the less sustainable category with an index of 49.56. The ecological, economic, and legal and institutional dimensions are the main focus in management, while the socio-cultural dimension is in the moderately sustainable category with an index of 68.03. The proposed sustainable management strategies include ecosystem-based zoning, utilization of non-timber forest products (NTFPs), increased community involvement, and institutional strengthening through inter-stakeholder synergies. Improving infrastructure, NTFP-based economic development, and community education are prioritized in an effort to support more effective management. The implementation of this strategy is expected to improve the sustainability of Kepau Jaya KHDTK management while improving the welfare of the surrounding community
