Abstract

Mosques serve as a place of worship and foster Muslims who live around the mosque, so the function of this can give a positive impact for Muslims' life. Mosques also function as a place for developing people's activities from the time of Prophet Muhammad to the present. It certainly plays important roles so the condition of the mosque, especially the interior, needs to have comfort element in order to get more solemnity when carrying out those activities. Mosque Al-Hidayah is located in Kampung Belentuk RT 001 RW 001, Kelurahan Cimahpar, Kecamatan Bogor Utara, Kota Bogor. This Belentuk village area has a land area of 23 hectares with a Muslim population of 1571 and 807 of them are men. This village has three mosques which Masjid Al-Hidayah is one of them. At this time, mosque Al-Hidayah has land area of 339 m2 with a building area of 128,9 m2 so that the room capacity can only accommodate 106 people. The number of men of Kampun Belantuk are divided into those three mosques of the village, even so, Mosque Al-Hidayah is not able to accommodate the number of people especially on Friday prayer because the number of worshipers is more than the current capacity of the mosque. The result of the analysis shows the need for prayer space is 330 m2 to accommodate 270 worshipers in prayer activities, especially Friday prayers, then the result of the analysis of the existing concrete structure were carried out by means of a concrete bounce test using the Hammer test, it is known that the average value of the concrete quality in the column is fc'=13.34 MPa, the block is equal to fc'=14.41 MPa. It indicates that the quality of the existing concrete of the Al-Hidayah Mosque does not meet the requirements of SNI 2847-2019 Article 19.2 concerning the minimum allowable normal concrete quality, then the design is carried out according to space requirements and a structural analysis is carried out on the planned design. The planned design is based on the existing space and land requirements which are 15 m x 14 m with a height of 3.5 m per floor and structural analysis is declared safe.

Abstract

ABSTRAKKonsep sistem drainase yang berkelanjutan saat ini telah menjadi isu utama dalam rangka mengurangi dampak perubahan iklim terhadap keberlangsungan sumber daya air. Konsep utama sistem drainase berkelanjutan adalah mengelola limpasan permukaan dengan cara mengembangkan fasilitas untuk menahan air hujan, seperti sumur resapan, dan kolam retensi. Universitas Ibn Khaldun (UIKA) Bogor menempati lahan seluas 4.35 Ha di Kecamatan Tanah Sareal, Kota Bogor. Lahan di sekitar universitas merupakan lahan permukiman padat, pusat perbelanjaan, dan sekolah. Selain itu, pengembangan universitas yang menuntut dibangunnya gedung-gedung baru sebagai fasilitas pendidikan, mengakibatkan ketersediaan lahan terbuka untuk meresapkan air hujan ke dalam tanah, menjadi semakin berkurang. Kota Bogor dikenal sebagai kota dengan curah hujan tinggi, antara 3,500 sampai 4,000 mm pertahun. Dengan perhitungan kasar, terdapat potensi air sebesar 152,250 m3 air yang dapat diresapkan ke dalam tanah dan menjadi cadangan air bersih di kampus UIKA Bogor. Oleh karena itu, perlu direncanakan fasilitas penahan air hujan. Analisis kala ulang hujan dilakukan dengan menggunakan Metode Gumbel, intensitas hujan menggunakan Metode Mononobe, dan debit limpasan menggunakan metode rasional. Hasil analisis menunjukkan bahwa diperlukan   4 sumur resapan berbentuk lingkaran dengan diameter 1 m dan kedalaman 2 m di setiap bangunan. Penggunaan sumur resapan ini mampu menampung air sebesar 5.65 m3, dan mengurangi debit limpasan sebesar 0.02 m3/dtk.Kata kunci: Drainase berkelanjutan, sumur resapan, Kampus UIKA BogorABSTRACTThe concept of a sustainable drainage system has now become a major issue to reduce the impact of climate change on the sustainability of water resources. The main concept of a sustainable drainage system is to manage surface runoff by developing facilities to retain rainwater, such as infiltration wells and retention ponds. Ibn Khaldun University (UIKA) Bogor occupies an area of 4.35 hectares in Tanah Sareal District, Bogor City. The land around the university is a dense residential area, shopping centers, and schools. Also, the development of universities, which requires the construction of new buildings as educational facilities, has resulted in less availability of open land to absorb rainwater into the ground. Bogor City is known as a city with high rainfall, between 3,500 to 4,000 mm per year. With a rough calculation, there is a water potential of 152,250 m3 of water that can be infiltrated into the ground and become a clean water reserve on the UIKA Bogor campus. Therefore, it is necessary to plan rainwater retaining facilities. Rainfall analysis was performed using the Gumbel Method, rainfall intensity using the Mononobe method, and runoff discharge using the rational method. The results of the analysis show that 4 circular infiltration wells are required with a diameter of 1 m and a depth of 2 m in each building. The use of these infiltration wells is able to accommodate 5.65 m3 of water and reduce runoff by 0.02 m3 / s.Keywords: Sustainable drainage, infiltration wells, UIKA Bogor Campus

Abstract

ABSTRAKTebing sungai merupakan daerah yang rawan terhadap erosi yang diakibatkan oleh aliran air. Erosi yang berlangsung terus menerus mengakibatkan longsor. Secara umum, jenis tanah di Kabupaten Bogor didominasi oleh latosol yang mudah erosi, selain itu dikarenakan curah hujan yang tinggi dan juga meningkatkan risiko longsor. Salah satunya adalah kejadian longsor pada tebing Sungai Ciliwung pada ruas Kampung Legok Nyenang RT.01//03, Desa Leuwimalang, Kecamatan Cisarua. Panjang longsoran mencapai 27 meter dengan ketinggian 10,20 meter. Struktur dinding penahan tanah diperlukan untuk mencegah terjadinya longsor yang lebih luas lagi. Mempertimbangkan kondisi lereng dan parameter fisis tanah, maka direncanakan dinding penahan tanah jenis kantilever untuk wilayah ini. Hasil analisis metode Mononobe-Okabe menunjukkan nilai keamanan dinding penahan tanah terhadap geser sebesar 0,36, dan terhadap guling sebesar 0,21, angka keamanan tersebut lebih rendah dibandingkan angka keamanan yang disyaratkan, yaitu 1,5 dengan demikian dinding penahan tanah rencana tidak kuat menahan tekanan tanah yang ada di belakangnya. Oleh karena itu, kekuatan dinding sepenuhnya dialihkan ke tanah dasar, dengan menggunakan fondasi bored pile. Hasil analisis daya dukung tanah, diperoleh nilai kapasitas ultimit aman (qs)sebesar 223,93 kN/m2 yang lebih besar dibandingkan nilai total beban vertikal, yaitu 204,52 kN/m2, sedangkan kapasitas ijin satu fondasi mencapai 569.89 kN.Kata Kunci: Sungai Ciliwung, tebing, longsor, dinding penahan tanah, kantileverABSTRACTRiverbanks as areas prone to erosion caused by water flow. Continuous erosion causes landslides. In general, soil types in Bogor Regency are dominated by latosols which are easily eroded, apart from that it is due to high rainfall and also increases the risk of landslides. One of them is a landslide incident on the cliffs of the Ciliwung River on the section of Legok Nyenang RT.01 / 03, Leuwimalang Village, Cisarua District. The length of the landslide reached 27 meters with a height of 10.20 meters. The structure of the retaining wall is needed to prevent more extensive landslides. Considering the slope conditions and physical parameters of the soil, a cantilever-type retaining wall is chosen for this area. The results of the analysis Mononobe-Okabe method show that the safety value of the retaining wall against shear is 0.36, and against rolling is 0.21, This safety figure is lower than the required safety figure, which is 1.5, thus the retaining wall of the planned soil is not strong enough to withstand the ground pressure behind it. Therefore, the strength of the walls is completely transferred to the subgrade, using a bored pile foundation. The results of the soil bearing capacity analysis showed that the ultimate safe capacity (qs) value was 223.93 kN /m2 which was greater than the total vertical load value, which was 204.52 kN /m2, while the permitted capacity of one foundation reached 569.89 kN.Keywords: Ciliwung River, cliffs, landslides, retaining walls, cantilever.
