Aplikasi Program HEC-RAS 5.0.3 Pada Studi Penanganan Banjir

Sungai Krueng Tukah memiliki DAS 59,51 Km2 dan panjang 25 Km serta bermuara di Selat Malaka. Sungai Krueng Tukah mengalami perubahan  kondisi sungai, tataguna lahan dan pertumbuhan penduduk sehingga sungai tidak lagi berfungsi secara optimal. Banjir pada Sungai Krueng Tukah menimbulkan kerusakan bangunan, lahan pertanian, dan lingkungan hidup. Hal ini terjadi di Kabupaten Pidie, khususnya di Daerah Aliran Sungai (DAS) Krueng Tukah. Penelitian ini bertujuan untuk menganalisis kemampuan volume tampang sungai Krueng Tukah dalam menampung debit periode ulang Q2, Q5, Q10, Q25 sampai Q50 tahun dengan menggunakan Program HEC-RAS 5.0.3 dan memberikan solusi persoalan banjir yang ada di sepanjang sungai. Metode yang digunakan adalah studi kasus. Lokasi penelitian adalah Sungai Krueng Tukah, Kota Sigli, Kabupaten Pidie, Aceh Data primer diperoleh dengan melakukan survei topografi dan pengamatan langsung kondisi sungai dan wawancara. Data sekunder berupa data curah hujan dari stasiun Keumala, Kota Bakti dan Padang Tiji. Hasil penelitian menunjukkan Curah hujan R2 sebesar 94,85 mm, R5=125,56 mm, R10= 48.65 mm, R25=181,21 mm dan R50=211,82 mm. Debit banjir diperoleh sebesar Q2=59,28 m3/det, Q5=96,05 m3/det, Q10=123,71 m3/det, Q25=155,52 m3/det dan Q50=201,47 m3/det. Dari hasil perhitungan terlihat Sungai Krueng Tukah tidak mampu menampung banjir lebih dari Q25 tahun. Penanganan normalisasi sungai dan kolam retensi adalah upaya penanganan banjir sungai Krueng Tukah yang harus dilakukan.Krueng Tukah River with a catchment area 59.51 Km2 and length is 25 km and downstream into the Malacca Strait. The Krueng Tukah River experienced changes in river conditions, land use, and population growth so that the river no longer functioned optimally. Floods on the Krueng Tukah River caused damage to buildings, agricultural land, and the environment. This happened in Pidie District, especially in the Krueng Tukah catchment area. This study aims to analyze the bankfull capacity of the Krueng Tukah river to accommodate return period Q2, Q5, Q10, Q25 to Q50 years with the HEC-RAS 5.0.3 Program and provide solutions to flood problems the river. The method used is a case study. The research locations were the Krueng Tukah River, Sigli City, Pidie District, Aceh. Primary data was obtained by topographic surveys and field observation of river conditions and interviews. Secondary data in the form of rainfall data from Keumala Station, Bakti City, and Padang Tiji. The results showed that R2 rainfall was 94.85 mm, R5 = 125.56 mm, R10 = 48.65 mm, R25 = 181.21 mm and R50 = 211.82 mm. Flow discharge was obtained at Q2 = 59.28 m3 / sec, Q5 = 96.05 m3 / sec, Q10 = 123.71 m3 / sec, Q25 = 155.52 m3 / sec and Q50 = 201.47 m3 / sec. The calculation results, it was that the Krueng Tukah River was unable to accommodate floods for more than Q25 years. Handling the normalization of rivers and retention ponds is an effort to handle the floods of the Krueng Tukah river that must be done

Management of breeding  activities consists of feed aspect, sex ratio, reproduction, health, and other needs. Jalak social behavior in UPKPJB Tegal Bunder consists of 9 behaviors consisting of interdisciplinary behavior, approaching each other, making out, marrying, cleaning the beak, chasing each other, pecking each other, mutual voices and nursery care. From the observation, there is some male and female behavior. The highest social behavior is performed by females about 420 times, while males are about 388 times during observation time

Pengenalan dan Pemanfaatan Limbah Kaca Menjadi Produk Bernilai

Glass waste is harmful if it is disposed of and mixed with other waste. A special disposal site is needed to avoid injuring the hands and feet of the garbage collectors, especially at the Final Disposal Site (TPA). Glass waste highly consists of silica (SiO2), which is needed in cement. Glass waste is crushed by a mechanical method using a crusher, creating glass powder with an average size of 54 µm. Cement is mixed with glass powder in a ratio of 4:1. Water cement factor (FAS) is used at 0.3. The partners in this community service activity are primary school-age children in Ateuk Lam Ura Village, Simpang Tiga District, and Aceh Besar District. The success of the resulting product is indicated by its compressive strength, the hardening of cement and glass powder, and the product's visual appearance without any visible pores. The product has good strength and looks neat with a solid surface. The compressive strength of the product obtained is 3.21. Partners are interested and can apply glass waste to flower pots properly
