Abstract

Site Gurimbang Mine Operation (GMO) ialah site penambangan oleh PT Berau Coal yang menerapkan metode penambangan terbuka. Metode ini akan menyebabkan terbentuknya cekungan yang luas sehingga berpotensi menjadi daerah tampungan air saat terjadi hujan. Air tidak dapat dialirkan di luar wilayah dapat menggangu kegiatan operasional penambangan, oleh karena itu aspek hidrologi harus sangat diperhatikan. Evaluasi sistem drainase di GMO sejauh ini menggunakan software HEC-RAS untuk menghitung kapasitas tampung salurannya. Studi ini ditujukan untuk melakukan pemodelan software SWMM sebagai terobosan baru dalam melakukan evaluasi sistem drainase. Dilakukan evaluasi terhadap kapasitas tampung saluran ditinjau dari teknologi drainase yang digunakan dan kerapatan aliran memanfaatkan pemodelan software HEC-RAS 6.2 serta SWMM 5.2. Serta analisa perbandingan hasil running simulasi antara HEC-RAS dan SWMM, sehingga nantinya dapat diketahui kekurangan dan kelebihan dari kedua software tersebut. Kedua software tidak menunjukan kapasitas saluran drainase dengan skala angka, namun kedua software tersebut menggambarkanya dalam bentuk simulasi yang berbeda pada setiap titik saluran yang dimodelkan. Pada HEC-RAS fitur view disajikan melalui fitur view cross section, view profiles, view 3d multiple cross section plot. Sedangkan pada SWMM terdapat fitur view profiles, view time series plot, fitur halaman map,dan fitur query. Hasil running kedua software tidak dapat dibandingkan karena menghasilkan tabel dengan output yang berbeda. hasil running simulasi software HEC-RAS saluran dinyatakan aman pada saat nilai W.S. Elev (elevasi muka air saluran) dibawah nilai Ground (elevasi tinggi tanggul saluran). SWMM menyatakan saluran aman atau tidak meluap ketika nilainya Max/Full Depth (tinggi maksimum saluran hasil simulasi) tidak melebihi dari tinggi saluran eksisting, atau bisa juga dilihat melalui fitur query Namun dari berbagai kelebihan yang ditawarkan oleh SWMM dapat disimpulkan bahwa secara penggunaan SWMM jauh lebih praktis dari pada HEC-RAS dalam memodelkan sistem drainase tambang yang ada.

Abstract

Kelompok Tani “Sampurna” masih menghadapi kendala dalam penyediaan pakan sapi potong, terutama rendahnya kualitas nutrisi pakan, belum optimalnya pemanfaatan bahan pakan lokal, dan belum tersusunnya ransum sesuai kebutuhan ternak. Kegiatan ini bertujuan meningkatkan kualitas nutrisi pakan sapi potong berbasis bahan lokal melalui formulasi produk pakan, pengolahan pakan, dan penguatan kapasitas peternak. Metode yang digunakan adalah pendekatan partisipatif-deskriptif melalui observasi awal, penyuluhan, pelatihan, praktik formulasi dan pengolahan pakan, serta evaluasi hasil kegiatan. Produk pakan yang dihasilkan meliputi pakan steaming up, pakan flushing, konsentrat penggemukan, dan pakan lengkap. Hasil analisis menunjukkan bahwa kandungan protein kasar pakan steaming up, flushing, konsentrat penggemukan, dan pakan lengkap berturut-turut sebesar 16,43%; 15,34%; 14,40%; dan 12,20%. Pakan steaming up dan flushing memiliki kandungan protein lebih tinggi sehingga lebih sesuai untuk mendukung kebutuhan nutrisi ternak betina pada fase reproduksi, sedangkan pakan lengkap memiliki kandungan serat kasar tertinggi sebesar 21,41% sehingga lebih sesuai digunakan sebagai pakan harian. Kegiatan ini menunjukkan bahwa bahan pakan lokal dapat diolah menjadi beberapa produk pakan dengan kualitas nutrisi yang berbeda sesuai fungsi penggunaannya. Penerapan formulasi yang tepat, teknologi pengolahan pakan, dan dukungan sarana operasional mampu memperkuat sistem pengelolaan pakan yang lebih terencana, efisien, dan berkelanjutan pada tingkat kelompok peternak.

Abstract

The Porong River is one of the rivers that faces high anthropogenic impacts, such as surfactant waste from detergents. The hematology of Javanese carp (Barbonymus gonionotus) serves as a sentinel organism that can be used as a biomarker for the waters of the Porong River. The aim of this study is to analyze the water quality status of the Porong River polluted with surfactants using the STORET method, as well as its impact on the hematology of Javanese carp using regression and correlation analysis. The research employed a descriptive survey method. The results of the study indicated that the Porong River was categorized as moderately polluted. The average highest surfactant concentration reached 7.2 mg/L, leading to an increase in TSS to 107.95 mg/L and a decrease in DO to 1.80 mg/L. Surfactants exhibited a negative correlation with erythrocytes (91.2%), hematocrit (47.7%), and hemoglobin (60.6%), indicating that the higher the surfactant concentration, the lower the number of erythrocytes, hematocrit levels, and hemoglobin levels in Javanese carp. Conversely, there was a positive correlation between surfactants and leukocytes (56.7%) and blood glucose (66.7%), suggesting that the higher the surfactant concentration, the higher the number of leukocytes and blood glucose levels in Javanese carp.

Abstract

This study evaluates the performance of CORDEX-SEA precipitation data and applies bias correction for future rainfall projection in the Sutami Reservoir catchment, Indonesia, which has an important role in irrigation and flood control management. Observed rainfall data for 1995–2024 were compared with CORDEX-SEA outputs under the RCP 4.5 and RCP 8.5 scenarios to assess model performance during the present-day period. The model generally overestimated observed rainfall, with average 10-day rainfall values of 86.09 mm/10-day (RCP 4.5) and 89.49 mm/10-day (RCP 8.5), compared to 56.19 mm/10-day from observations. Bias correction was performed using the Linear Scaling (LS) and Quantile Mapping (QM) methods because of their robustness and effectiveness in reducing systematic bias in precipitation data while preserving the temporal characteristics of climate model outputs. The corrected results showed substantial improvement, with the correlation coefficient increasing to 0.95, Nash–Sutcliffe Efficiency reaching 0.90, RMSE-standard deviation ratio decreasing to 0.32, and Percent Bias reducing to approximately 2–3%. Rainfall projections for 2025–2030 indicate a decreasing rainfall trend under both scenarios. This study demonstrates that LS and QM can effectively improve CORDEX-SEA precipitation data reliability for watershed-scale climate change and water resources assessments in Indonesia.

Abstract

Limited access to adequate bathing, washing, and toilet facilities (MCK) remains a significant problem for residents of RT-03/RW-10, Polaman Sub-Village, Kalirejo Village, Lawang District, Malang Regency, so that some residents still use the river to meet their basic sanitation needs, potentially reducing their health and environmental quality. This Community Service Activity aims to provide simple WASH facilities that meet sanitation standards while promoting behavioral changes toward clean and healthy living through community participation. The implementation methods included an initial survey and interviews to identify the socio-cultural and environmental conditions, discussions to develop solutions with the RT administrators and residents, socialization with the PKK women's group, the construction of the MCK through the self-help efforts of students, donors, and the community during July-October 2025, and an evaluation in November 2025 through field observations, interviews, and documentation. The results of the activity include the construction of a simple, functional, and easy-to-operate toilet two units with a layout that meets comfort standards and better manages wastewater flow; increased community understanding of the importance of sanitation and environmental conservation; and a stronger spirit of cooperation in maintaining shared facilities. Overall, this program was deemed effective by residents and neighborhood association administrators in improving access to basic sanitation, reducing dependence on rivers as a means of sanitation, and supporting the creation of a cleaner, healthier, and more sustainable residential environment, while also providing a model for simple sanitation facilities that can be replicated in similar areas.
