Abstract

Kelurahan Pandean Lamper merupakan salah satu daerah rawan banjir di Kota Semarang, karena terletak di DAS Sungai Banjir Kanal Timur. Penanganan terhadap banjir di wilayah tersebut telah dilakukan oleh pemerintah berupa normalisasi sungai dan saluran drainase. Banjir Kanal Timur (BKT) adalah satu sistem pengendali banjir Kota Semarang yang terletak di bagian timur Kota Semarang. Sungai ini memiliki panjang ± 14,50 km. Proyek normalisasi Sungai Banjir Kanal Timur membentang dari hulu di Bendungan Pucanggading hingga berakhir Muara Sungai di Laut Jawa. Dalam tahap I, normalisasi dilakukan sepanjang 6,7 kilometer, dari muara hingga Jembatan Majapahit. Untuk menjamin keberlanjutan pengelolaan normalisasi sungai dan saluran drainase, diperlukan keterlibatan banyak pihak, termasuk partisipasi masyarakat yang bertempat tinggal di dalamnya. Oleh sebab itu warga di kawasan tersebut perlu mendapatkan edukasi bagaimana menjaga keberlanjutan normalisasi sungai dan saluran drainase. Warga Kelurahan Pandean Lamper memerlukan edukasi agar dapat ikut berpartisipasi dalam pemeliharaan sungai dan saluran drainase. Edukasi yang diberikan meliputi pemahaman tentang penyebab dan dampak banjir, penanganan banjir serta pemeliharaan bangunan infrastruktur pengendali banjir. Warga Kelurahan Pandean Lamper masih banyak yang tidak memahami bangunan pengendali banjir yang ada di sekitar lingkungan mereka. Melalui edukasi yang diberikan dalam penyuluhan, diharapkan warga Pandean Lamper bisa memahami peran yang harus dilakukan dalam menjaga keberlangsungan bangunan pengendali banjir. Pandean Lamper Village is one of the flood-prone areas in Semarang City, because it is located in the East Flood Canal River Basin. The government has taken steps to deal with flooding in the area by normalizing rivers and drainage channels. The East Flood Canal (BKT) is a flood control system for the City of Semarang which is located in the eastern part of the City of Semarang. This river has a length of ± 14.50 km. The East Flood Canal River normalization project stretches from the upper reaches of the Pucanggading Dam to the end of the River Estuary in the Java Sea. In phase I, normalization is carried out along 6.7 kilometers, from the estuary to the Majapahit Bridge. To ensure the sustainability of the normalization of river and drainage channel management, it requires the involvement of many parties, including the participation of the people who live in them. Therefore, residents in the area need to receive education on how to maintain the sustainability of normalization of rivers and drainage channels. The residents of Pandean Lamper Village need education so that they can participate in the maintenance of rivers and drainage channels. The education provided includes an understanding of the causes and impacts of floods, flood management and maintenance of flood control infrastructure buildings. There are still many residents of Pandean Lamper Village who do not understand the flood control buildings in their surroundings. Through the education provided in the counseling, it is hoped that the residents of Pandean Lamper can understand the role that must be carried out in maintaining the sustainability of flood control buildings.

Abstract

Irrigation System Performance Index (ISPI) is often used as a parameter in making decisions about the use of irrigation canals. The increase in rice production is dependent on a good condition of physical infrastructures, including the main building, the carrier canal and the buildings on the carrier canal. Performance assessment of Physical Infrastructure and Plant Productivity in Sungapan irrigation area of Pemalang Regency indicated that the physical infrastructure performance in 2012 - 2022 was 38.42%, increasing 3.22%. While the performance assessment of Plant Productivity was 14.96%, increasing 2.99%. Based on the multiple regression analysis using simultaneous test (F), the Physical Infrastructure component was indicated to influence the plant productivity. Meanwhile, based on the partial test (t), the physical infrastructure component partially did not have a significant influence on the plant productivity

Abstract

Perkembangan kawasan perkotaan yang pesat telah menyebabkan perubahan tata guna lahan yang signifikan, terutama berkurangnya area resapan alami akibat pembangunan permukiman, infrastruktur, dan industri. Kondisi ini berdampak pada meningkatnya limpasan permukaan, menurunnya kapasitas infiltrasi, serta berkurangnya cadangan air tanah. Untuk mengatasi permasalahan tersebut diperlukan inovasi teknologi konservasi air tanah yang lebih efektif, salah satunya melalui penerapan Pipa Resapan Horisontal (PRH). Teknologi ini dirancang untuk meningkatkan laju infiltrasi dengan memanfaatkan pipa berlubang yang dipasang mendatar di bawah permukaan tanah, sehingga mampu bekerja optimal meskipun muka air tanah relatif dangkal. Penelitian ini bertujuan untuk memodelkan aliran air tanah di sekitar PRH menggunakan pendekatan regresi non-linier guna memahami interaksi variabel hidrogeologi yang memengaruhi infiltrasi. Metode penelitian dilaksanakan melalui eksperimen lapangan di Kelurahan Jabungan, Kota Semarang, dengan pengumpulan data meliputi muka air tanah, kadar air tanah, debit infiltrasi, serta jarak lubang pantau dari PRH. Uji lapangan dilakukan sebanyak tiga kali dalam kondisi berbeda. Selanjutnya, data dianalisis menggunakan perangkat lunak NCSS 2023 untuk memperoleh model regresi non-linier yang representatif. Hasil penelitian menunjukkan bahwa variabel waktu, jarak lubang pantau, dan kadar air tanah berpengaruh signifikan terhadap perubahan muka air tanah di sekitar PRH. Model regresi non-linier yang diperoleh memiliki tingkat keandalan tinggi, ditunjukkan dengan nilai koefisien determinasi (R²) berkisar antara 0,79–0,83. Hal ini membuktikan bahwa PRH mampu meningkatkan infiltrasi air tanah secara efektif, sekaligus memberikan gambaran matematis mengenai hubungan antarvariabel hidrogeologi. Kesimpulan penelitian ini menegaskan bahwa PRH merupakan teknologi yang potensial untuk mitigasi banjir dan konservasi air tanah di kawasan perkotaan. Sebagai rekomendasi, model yang dikembangkan dapat dijadikan dasar perencanaan teknis penerapan PRH pada berbagai kondisi tanah dan tata guna lahan, serta dikombinasikan dengan metode konservasi lainnya untuk memperoleh hasil yang lebih optimal.

Abstract

Banjir di Kota Semarang menjadi permasalahan yang terus berulang dan mengancam. Studi ini difokuskan pada Sungai Penggaron  di Hulu Bendung Pucang Gading sebagai salah satu sumber utama banjir. Penelitian ini bertujuan untuk mengetahui kapasitas penampang sungai sebelum dan sesudah normalisasi. Tahapan penelitian dilakukan dengan perhitungan debit banjir rancangan dengan metode polygon thiessen dan log pearson III serta pemodelan HEC - RAS  .  Hasil studi menunjukan Sungai Penggaron tidak mampu menampung debit banjir Q2 (253.4 m3/det) sehingga perlu dilakukan normalisasi pada hulu Bendung Pucang Gading. Normalisasi yang dilakukan adalah dengan pengerukan sedimentasi pada dasar sungai dan peninggian tanggul sungai. Hasil normalisasi Sungai Penggaron di hulu Bendung Pucang Gading menunjukkan penurunan muka air yang signifikan dan dapat menampung debit banjir Q100 (517,44 m3/det). Kesimpulan dari Analisa di atas adalah dengan dilakukannya normalisasi sungai di hulu Bendung Pucang Gading akan meningkatkan kemampuan pengendalian banjir di bagian hulu Bendung Pucang Gading.

Abstract

This study developed a water level prediction model using the integration of Artificial Neural Network (ANN) and Long Short-Term Memory (LSTM). ANN maps nonlinear relationships between hydrological parameters, while LSTM captures temporal dependence patterns in time series data. The comparison results of four models—Linear Regression, ANN, LSTM, and ANN–LSTM hybrid—showed that the neural network-based model provided significantly better prediction performance than the linear model. The Linear Regression model produced the largest error (MSE 0.0175; RMSE 0.128; MAE 0.103; R² 0.785), followed by ANN with a significant increase in accuracy (MSE 0.0114; RMSE 0.101; MAE 0.0549; R² 0.874). LSTM provided better results (MSE 0.0048; RMSE 0.067; MAE 0.0472; R² 0.902), but the best model was the hybrid ANN–LSTM with the lowest error value (MSE 0.00417; RMSE 0.063; MAE 0.0388) and the highest R² (0.937). This combination is able to capture nonlinear patterns and temporal dynamics more optimally, resulting in stable and accurate predictions. In addition, this study shows that the Duflow hydrodynamic model has the potential to be developed as a mitigation simulation tool for water level management, such as testing extreme rainfall scenarios, spatial changes, flood control infrastructure operations, channel optimization, and simulating the impacts of climate change.
