Abstract

The Bringin River is a river in West Semarang, Semarang City, with the Tugu Region drainage subsystem. The Bringin watershed covers parts of the area in Tugu District, Ngaliyan District, and Mijen District. The overflow of water caused by high rainfall resulted in river flooding. The cross-section of the Bringin River cannot accommodate the magnitude of the flood discharge. The purpose of this study was to determine the cross-section of the Bringin River which was experiencing an overflow by carrying out a Hydrological Analysis and using the HEC-RAS 6.3.1 Program as a 1-dimensional cross-sectional design. Calculation of the planned flood discharge with periods of 2, 5, 10, 25, and 50 years using the Nakayasu Synthetic Unit Hydrograph method with a peak discharge Q2years : 52.45 m3/second, Q5years : 62.43 m3/second, Q10years: 68.44 m3/second, Q25years : 75.09 m3/second, and Q50years : 79.95 m3/second. The results of the calculation of the design discharge will be used in the HEC-RAS 6.3.1 programming so that from these results it can be seen that several cross-sections of the river have flood overflows that exceed the capacity of the Bringin River under review.

Abstract

Kelurahan Krendang memiliki permasalahan mendasar sebagai salah satu kawasan terpadat di DKI Jakarta, bahkan Asia Tenggara. Dengan luas ruang terbuka hijau +2,86% dari total luas Kelurahan Krendang, dan kepadatan penduduk ­­+78.000 penduduk/km2 semakin menambah permasalahan turunan berikutnya dimana ruang terbuka publik yang ada tidak dapat mengakomodir kebutuhan warga untuk berinterasksi, bersosialisasi, dan berkomunal.  Penyediaan sarana dan prasarana lingkungan di kawasan ini dapat dikatakan belum memenuhi persyaratan minimal pelayanan lingkungan, khususnya ruang publik atau ruang komunal. Berdasarkan data eksisting melalui JakartaSatu, luas ruang terbuka hijau di Kelurahan Krendang hanya +2,86% dari total luas Kelurahan Krendang, sangat jauh dari standar minimal ruang terbuka hijau publik yaitu 20% dari luas kawasan terkait. PkM ini bertujuan untuk memberikan pengetahuan teknis kepada warga untuk mengoptimalkan ruang sosial-komunal yang ada, melalui percontohan rancangan Green Co-Space. Metode yang digunakan adalah dengan pendekatan participatori Masyarakat dalam menentukan potensi dan masalah, hingga ditetapkan fasilitas sosial-komunal sekolah Nurul Wihdah sebagai objek percontohan. Hasil kegiatan PkM ini berupa gambaran rancangan Green Co-Space sekolah Nurul Wihdah, yang kemudian dipaparkan dan didiskusikan bersama warga. Implikasi dari PkM ini memperlihatkan pemahaman masyarakat meningkat 18-27% dibandingkan sebelum dilaksanakannya PkM, tentang pentingnya ruang komunal yang green, yang mengintegrasikan ruang dalam dan ruang luar.

Abstract

Perubahan tata guna lahan menyebabkan berkurangnya daerah resapan air hujan. Hal ini akan memicu meningkatnya debit limpasan permukaan. Perencanaan drainase yang memadai dibutuhkan untuk menghindari banjir oleh limpasan air berlebih. Perencanaan drainase dengan konsep zero delta run off menjadi solusi atas permasalahan tersebut dengan menerapkan teknologi ekodrainase yang akan meresapkan air limpasan permukaan ke tanah sebanyak-banyaknya tanpa menambah beban drainase kawasan. Perencanaan drainase ini menggunakan metode distribusi gumbel, Rumus Mononoobe, serta menggunakan metode Federal Aviation Administration (FAA) untuk menghitung waktu pengaliran. Teknologi ekodrainase yang digunakan untuk menunjang konsep ini adalah adalah kolam retensi dan sumur resapan. Hasil perhitungan yang didapat dengan mengolah data adalah debit Kawasan sebelum dibangunnya perumahan Permata Puri Cibubur adalah 0,017 m3/detik untuk Cluster Y dan 0,016 m3/detik untuk Cluster Z. Setelah kawasan terbangun, debit kawasan mengalami kenaikan menjadi 0,1352 m3/detik pada Cluster Y dan 0,1154 m3/detik pada cluster Z. Penerapan teknologi ekodrainase seperti kolam retensi dan sumur resapan diharapkan menurunkan jumlah debit limpasan sehingga kawasan setelah dibangun memiliki debit yang sama seperti kawasan sebelum terbangun sehingga bisa tercapainya zero delta run off

Abstract

Siklus hidrologi yang dipengaruhi oleh kondisi lingkungan pada suatu daerah aliran sungai akan berdampak pada perubahan dan pergeseran intensitas curah hujan serta pola musiman. Dinamika perubahan tersebut akan mempengaruhi daya dukung sumber daya air pada suatu DAS. DKI Jakarta mengalami beberapa perkembangan diantaranya pertumbuhan penduduk dan penggunaan lahan. Sehingga mengakibatkan daya dukung lingkungan semakin menurun. Akibat penurunan daya dukung mengakibatkan terjadinya pergeseran atau perubahan siklus hidrologi.   Penelitian ini dilakukan untuk menganalisis proyeksi curah hujan berdasarkan skenario perubahan iklim yang berdampak pada daya dukung sumber daya air pada  Daerah Aliran Sungai khususnya wilayah Provinsi DKI Jakarta. Skenario perubahan iklim yang digunakan adalah skenario Representative Concentration Pathways (RCP) 4.5 dan 8.5. Data curah hujan yang digunakan sebagai baseline (1994-2023) merupakan data hasil pengamatan dan data CHIRPS. Dalam memprediksi curah hujan 30th mendatang (2024-2073), digunakan data satelit Global Climate Models (GCM) yaitu CANESM5.

Abstract

The old city area is a tourist area strategically located in the heart of the capital city of DKI Jakarta. The Krukut river is one of the rivers that often overflow, which is one of the causes of flooding in Jakarta. This study aims to determine the water level of the Krukut river so that it can be used as a reference in handling flood disaster mitigation. This study uses the Nakayasu method and the Snyder method to calculate flood discharge, with a return period of up to 100 years. Meanwhile, for modeling the river water level using the HEC-RAS 5.0.07 application. The results of this study, specifically on the upstream cross-section until 300 meters after that TMA, are pretty high with plan one, which is 3 m deep from the bottom of the channel. However, the track still has a sufficient guard height of about 1.5 m. In other words, no overtopping/ river water does not overflow in the upstream area with a return period of 10 years and 25 years. However, due to the narrower channel section, the upstream region is more prone to flooding than the middle downstream area. From the modeling results, the channel prone to erosion is the section 10 track which is widening at the same time that the channel is not filled with the CONCRETE channel, so it is effortless to erode. For this reason, it is recommended to repair the walls of the river/channel to avoid scouring, especially if there is a high/extreme discharge.

Abstract

Ciujung Irrigation Area (DI) has an area of 21,350 ha. The Ciujung Irrigation Area Irrigation Network is still found to be quite high sedimentation, so that the distribution of water for agricultural needs and other community needs has not been able to be carried out optimally. The purpose of optimizing the planting pattern is to determine the maximum price of the crop that a field with different types of crops can produce. Optimization in this study used a linear program using the POM QM application. In this optimization study, 4 alternatives were planned with 2 different crops, namely corn and peanuts. In the planting pattern, alternative 1 starts planting in December I, alternative 2 starts planting in December II, alternative 3 starts planting in January I, alternative 4 starts planting in January II. The alternative planting pattern chosen is alternative 2 by producing an area of MT I Rice covering an area of 21,350 ha, MT II Rice covering an area of 3671.62 ha, Palawija covering an area of 84.98 ha and the maximum profit obtained in a year is IDR 595,113,300,000

Abstract

Indonesia experienced a significant spike in cyberattacks, averaging 158 attacks per second, indicating a high risk for digital systems, especially in the government and business sectors. The large number of attacks has caused financial losses and damaged public trust, indicating that data protection is not optimal. Traditional authentication systems based on centralized servers increase the risk of document leaks and forgery. To address this, this study proposes a Blockchain-based digital signature solution called AlphaSign. This technology strengthens data resilience and document verification reliability with an Agile Scrum approach, enabling iterations that are responsive to user needs. Alpha Sign aims to create a secure Blockchain-based digital signature system, prevent document forgery, and accelerate verification through QR code automation. This system supports the development of sustainable digital infrastructure, in line with the SDGs, especially Goal 9 (Infrastructure Innovation) and Goal 16 (Resilient Institutions). With Blockchain technology, Alpha Sign records each signature in a decentralized manner, reduces the risk of hacking, and enables real-time document verification through QR codes, providing security and transparency for large agencies and the public sector.
