Abstract

Permasalahan lingkungan yang umumnya sering terjadi adalah pengelolaan sampah yang kurang baik.Perlu dilakukan penanganan yang serius dalam pengelolaan sampah terutama penentuan rute dalam pengangkutan sampah.Penelitian ini dilakukan dengan menganalisa proses alur pergerakan sampah dari masyarakat hingga berakhir di TPA agar dapat diketahui masalah yang terdapat dalam proses pengelolaan sampah di Kota Kupang. Kemudian dilakukan perhitungan jumlah produksi sampah berdasarkan jumlah penduduk kota Kupang pada tahun 2016 diperoleh jumlah produksi sampah sebesar 585,447 m3/haridan memprediksi jumlah produksi sampah dalam kurun waktu 5 tahun kedepan dengan perbandingan 3 metode dimana metode yang paling kritis adalah metode eksponensial dengan jumlah penduduk sebanyak 455.035 orang dan jumlah produksi sampah sebesar 473,010 m3/hari, selanjutnya dilakukan perhitungan kebutuhan jumlah TPS berdasarkan jumlah produksi sampah dan diketahui bahwa jumlah TPS masih dapat menampung jumlah produksi sampah untuk seluruh penduduk kota Kupang tetapi dalam hal persebarannya masih belum merata khususnya pada kecamatan Alak, Kelapa Lima, dan Kota Raja. Rute angkutan persampahan diperoleh berdasarkan hasil analisis saving Solver Add-Ins. Setelah diperoleh koordinat TPS dan rute angkutan persampahan divisualisasikan kedalam WEBGIS.Common environmental problems that often occur are poor waste management. A serious handling of waste management is needed, especially in determining the route in transporting wast. This research was conducted by analyzing the process of the movement of garbage from the community to end in TPA in order to know the problems contained in the process of waste management in Kupang City. Then the amount of waste production based on the total population of Kupang city in 2016 obtained the amount of waste production of 585.447 m3 / day and predicted the amount of waste production in the next 5 years with a comparison of 3 methods where the most critical method is the exponential method with a population of 455,035 people and the amount of waste production of 473,010 m3 / day, then calculated the needs of the number of TPS based on the amount of waste production and it is known that the number of TPS can still accommodate the amount of waste production for the entire population of Kupang city but in terms of its distribution is still uneven, especially in Alak, Kelapa Lima, and Kota Raja. The route of garbage transportation can be obtained based on saving Solver Add-Ins analysis. After the TPS coordinates are obtained and the trash routes are visualized into the WEBGIS.

Kota Kupang merupakan ibukota dari Provinsi Nusa Tenggara Timur yang termasuk dalam daerah rawan gempa. Pada penelitian sebelumnya dari Aprianto Nomleni (2016) telah mendapatkan nilai Peak Ground Acceleration (PGA) menggunakan metode Probability Seismic Hazard Analysis (PSHA). Dari nilai PGA tersebut dibuat grafik respon spectra percepatan terhadap periode. Dengan menggunakan respon spectra tersebut akan dilakukan analisis respon struktur untuk mendapatkan nilai defleksi lateral dari suatu struktur gedung beraturan dua dimensi di Kota Kupang. Tujuan dari penelitian ini adalah untuk mendapatkan respon struktur gedung beraturan 2 dimensi dengan menggunakan hasil penelitian Aprianto Nomleni (2016), respon spectra SNI 2002, dan respon spectra SNI 2012 sebagai beban gempa dengan menggunakan aplikasi SAP2000. Nantinya, akan membandingkan hasil antara ketiganya. Hasil analisis menghasilkan nilai perbedaan defleksi lateral akibat ketiga respon spectra itu berkisar 19,77 % sampai dengan 40,04 %. Nilai maksimum total drift sebesar 0,0003 – 0,0005 yang termasuk pada kategori Immediate Occupancy. Nilai maksimum interstory drift sebesar 0,0001 – 0,0002 yang termasuk pada kategori Immediate Occupancy.Kupang City is the capital of the East Nusa Tenggara Province which is included in earthquake-prone areas. In a previous study from Aprianto Nomleni (2016), the Peak Ground Acceleration (PGA) value was using the Probability Seismic Hazard Analysis (PSHA) method. From the PGA value the response graph is made spectra of acceleration to the period. By using the response spectra a structural response analysis will be carried out to obtain lateral deflection values from a two-dimensional irregular building structure in Kupang City. The purpose of this study was to obtain the response of 2-dimensional regular building structures by using the results of Aprianto Nomleni's research (2016), the response of the SNI 2002 spectra, and the response of the SNI 2012 spectra as earthquake loads using the SAP2000 application. This will later be compared between the three. The results of the analysis produced a difference in lateral deflection between the three response spectra ranging from 19.77% to 40.04%. The maximum value of total drift is 0,0003 - 0,0005 which is included in the category of Immediate Occupancy. The maximum value of inelastic drift is 0,0001 - 0,0002 which is included in the category of Immediate Occupancy.
