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

Abstrak:Kebakaran yang terjadi pada Tempat Pemrosesan Akhir (TPA) Cinangsi pada tahun 2015 menyebabkan TPA Nangkaleah di Kec. Wangunreja, Kab. Tasikmalaya harus dioperasikan lebih cepat, walau pun TPA Nangkaleah belum dilengkapi beberapa fasilitas pengolahan akhir, di antaranya adalah unit pengolahan lindi. Desain awal unit pengolahan lindi TPA Nangkaleah dinilai jauh lebih kecil daripada total timbulan lindi dari sampah yang didatangkan dari area pelayanan TPA Cinangsi dan rencana area pelayanan TPA Nangkaleah. Dengan demikian diperlukan desain fasilitas pengolahan lindi yang memiliki kapasitas jauh lebiih besar. Tujuan penelitian ini adalah untuk merencanakan desain unit pengolahan lindi berdasarkan proyeksi timbulan sampah dari 2 (dua) area pelayanan, data curah hujan dan proyeksi timbulan lindi. Hasil penelitian ini menunjukkan bahwa proyeksi debit timbulan lindi adalah sebesar 0,94 m3/hari. Fasilitas pengolahan lindi yang direncanakan terdiri dari 2 (dua) unit kolam penampungan lindi dengan kapasitas masing – masing kolam sebesar 30 m3, kolam stabilisasi dengan kapasitas 20 m3, kolam aerasi dengan kapasitas 20 m3, kolam maturasi dengan kapasitas 15 m3, sistem resirkulasi lindi dan lahan basah (wetland). Fasilitas tersebut dinilai mampu menurunkan kadar pencemar lindi hingga memenuhi baku mutu lingkungan.Kata Kunci: Tempat Pembuangan Akhir Sampah, lindi, fasilitas pengolahan lindi, kadar pencemar, baku mutu lingkungan.Abstract: A fire disaster that occurred at the Cinangsi sanitary landfill in 2015 leads the Nangkaleah sanitary landfill in Wangunreja, Tasikmalaya must be operated earlier, even though the Nangkaleah landfill has not been equipped with several final processing facilities, including a leachate processing unit. The initial design of the leachate treatment unit at the Nangkaleah landfill is considered to be much smaller than the total leachate generation from waste imported from the Cinangsi's service area and the planned Nangkaleah's landfill service area. Thus, it is necessary to design a leachate treatment facility that has a much larger capacity. The purpose of this study is to plan the design of leachate treatment units based on projections of waste generation from 2 (two) service areas, rainfall data, and projections of leachate generation. The results of this study indicate that the projected discharge of leachate at Nangkaleah landfill is 0.94 m3/day. The leachate processing facility that is planned consists of 2 (two) units of leachate storage ponds with a capacity of 40 m3 each, a stabilization pool with a capacity of 20 m3, an aeration pool with a capacity of 20 m3, a maturation pool with a capacity of 15 m3, a leachate recirculation system and wetland area. The facility is considered capable of reducing levels of leachate pollutants to meet environmental quality standardsKeywords: Landfill, leachate, leachate treatment facility, pollutant levels, environmental quality standards.

Abstrak: Kontraktor seringkali mengalami kesulitan atau kendala-kendala saat menjalankan proyek, seperti ketersediaan bahan baku, ketersediaan tenaga kerja, faktor cuaca dsb. Oleh karena itu, perusahaan selaku pelaksana proyek harus mampu mengadakan pengendalian yang tepat agar dalam pelaksanaan kegiatan proyek dapat diselesaikan tepat waktu dengan biaya yang sesuai dengan rencana. Metode earned value dapat diguankan untuk mengetahui adanya penyimpangan varians biaya dan varians jadwal secara terpadu. Berdasarkan hasil penelitian dan perhitungan dengan menggunakan metode earned value pada proyek ruko Damara Village, dapat disimpulkan pada bulan Juni varian biaya sebesar Rp -621.705 dan varians jadwal sebesar Rp 2.482.070, untuk index kinerja sebesar 0,94 dan index kinerja jadwal sebesar 1,32. Sedangkan untuk bulan Juli varian biaya sebesar Rp -9.433.536 dan varians jadwal Rp -5.329.146 dengan index kinerja biaya sebesar 0,82 dan index kinerja jadwal sebesar 0,89 sehingga proyek pembangunan ruko bernilai negatif, artinya pelaksanaan proyek belum berjalan baik. Pada bulan Agustus varians biaya sebesar Rp 4.293.035 dan varians jadwal sebesar Rp -338.926, untuk index kinerja sebesar 1,16 dan index kinerja jadwal sebesar 0,99 mengalami kenaikan dikarenakan penambahan tenaga kerja dan sebagai akselerasi setelah masa libur kerja saat hari raya di bulan Juli 2017.Kata Kunci: pengendalian biaya, varian biaya, varian jadwal, metode earned value.Abstract: Contractors often experience difficulties or obstacles when carrying out projects, such as availability of raw materials, availability of labor, weather factors, etc. Therefore, as operators, developers must be able to carry out proper control so that the implementation of project activities can be completed on time at a cost according to plan. The earned value method can be used to find out the deviation of cost variance and schedule variance in an integrated manner. Based on the results of research and calculations using the earned value method on the Ruko Damara Village project, it can be concluded that in June the cost variant was IDR -621,705 and the schedule variance was IDR 2,482,070, for a performance index of 0.94 and a schedule performance index of 1.32. Whereas for July the cost variant was IDR -9,433,536 and the schedule variance was IDR -5,329,146 with a cost performance index of 0.82 and a schedule performance index of 0.89 so that the project index was negative, meaning that the project implementation was not going well. In August the cost variance was Rp.4,293,035 and the schedule variance was Rp.338,926, for the performance index of 1.16 and the schedule performance index of 0.99, an increase was due to the addition of labor and as an acceleration after the working holiday during holidays at July 2017.Keywords: cost management, cost variance, schedule variance, earned value method.
