"DKI Jakarta merupakan provinsi terpadat di Indonesia dengan produksi sampah hingga 3,11 juta ton pada tahun 2022. Komposisi sampah terbesar adalah sampah organik, sehingga penanganannya penting untuk dilakukan. Salah satu alternatif yang dapat dilakukan adalah pengomposan vermi. Oleh karena itu, penelitian ini dilakukan untuk mengetahui hasil kompos dari pengomposan vermi dan potensi penurunan massa sampah organik akibat pengomposan vermi. Penelitian ini dilakukan di TPS 3R Sadar Raya dengan metode kuantitatif melalui pendekatan eksperimental yang melibatkan persiapan reaktor, bedding, feedstock, serta pelaksanaan pengomposan vermi. Hasil dari kompos vermi akan dibandingkan dengan hasil kompos caspary di TPS 3R Sadar Raya berdasarkan standar SNI 19-7030-2004 dan Permentan No. 11 Tahun 2007. Hasil penelitian menunjukkan bahwa berdasarkan kontrol harian, pengomposan vermi berjalan baik dengan pH, kadar air, dan suhu pada rentang optimal. Kompos vermi juga menunjukkan warna dan bau seperti tanah. Namun, berdasarkan hasil uji laboratorium, hasil kompos vermi belum memenuhi parameter kadar air, C-organik, rasio C/N, pH, P2O5, dan K2O berdasarkan kedua standar. Maka, kompos vermi dinyatakan belum matang dan belum stabil apabila dibandingkan dengan hasil kompos caspary, sehingga perlu dilakukan penambahan waktu dari proses pengomposan dan proses curing ataupun penambahan variasi feedstock dengan kotoran hewan ternak.

DKI Jakarta is Indonesia's most populous province, generating up to 3,11 million tons of trash by 2022. Organic waste makes up the majority of waste, so it must be managed properly. One option is to compost using the vermi technique. As a result, the purpose of this study was to assess the compost production from vermi composting as well as the potential decrease in organic waste mass caused by vermi composting. This study was carried out at TPS 3R Sadar Raya utilizing a quantitative method combined with an experimental strategy that included the preparation of reactors, bedding, feedstock, and vermi composting. The results of vermi compost will be compared to the results of caspary compost at TPS 3R Sadar Raya using SNI 19-7030-2004 and Permentan 11/2007. The results showed that, based on daily management, vermi composting is performing well, with pH, moisture content, and temperature within the ideal range. In addition, vermi compost exhibited soil-like color and odor, indicating maturity. However, laboratory test findings show that the vermi compost does not meet the moisture content, C-organic, C/N ratio, pH, P2O5, and K2O criteria specified in SNI 19-7030-2004 and Permentan 11/2007. As a result, vermi compost is considered immature and unstable when compared to caspary compost, necessitating an extension of the composting and curing processes, as well as the addition of feedstock variations such as cattle manure."

"Timbulan sampah di Kota Jakarta Selatan mencapai 1,937.54 ton per hari di tahun 2021. Rata-rata timbulan sampah terus merangkak naik hingga 17 ton setiap tahunnya. Permasalahan ini diakibatkan oleh pengelolaan sampah yang kurang baik, salah satunya pengelolaan di tempat penampungan sampah (TPS). Kelurahan Pejaten Barat memiliki TPS yang berlokasi di belakang Kantor Kelurahan Pejaten Barat yang dinamakan TPS Siaga. TPS Siaga menampung sampah dari seluruh RW di Kelurahan Pejaten Barat dan lokasi lainnya. Dalam situs SIPSN, sampah yang masuk pada TPS Siaga di tahun 2022 mencapai 19,130.36 ton per tahun. Sedangkan sampah yang terkelola hanya sebesar 222.7 ton per tahun, perbedaan antara sampah yang masuk dengan yang dikelola sangat signifikan. TPS Siaga juga bersinggungan dengan kali, ketika hujan lebat dan/atau kali meluap terjadi bencana banjir. Penelitian dilakukan untuk mengkaji pengelolaan dan pengolahan sampah di TPS Siaga, mengukur berat dan volume timbulan sampah yang masuk, mengidentifikasi komposisi limbah dan persentase jenis sampah sesuai, dan menganalisis potensi reduksi sampah yang mampu dicapai oleh TPS Siaga. Metode penelitian yang digunakan pada penelitian ini adalah observasi dan wawancara untuk mengetahui pengelolaan sampah yang dilakukan pada TPS Siaga, pengukuran timbulan sampah menggunakan metode load-count analysis, dan identifikasi komposisi menggunakan SNI 19-3964-1994. Hasil penelitian menunjukkan timbulan sampah yang masuk ke TPS Siaga dari wilayah pelayanan Kelurahan Pejaten Barat sebesar 3,477.368 kg per hari dengan volume sebesar 31.174 m3 serta timbulan sampah sebesar 0.081 kg/orang/hari atau 0.729 L/orang/hari. Komposisi sampah didominasi oleh sisa makanan sebesar 46.61%. Persentase komposisi sampah lainnya ialah kayu/ranting/daun sebesar 1.16%, kertas/karton 10.78%, plastik 18.17%, logam 1.05%, kain/tekstil 6.38%, karet/kulit 0.23%, kaca 1.69%, B3 0.71% dan sampah lainnya 13.21%. Pengelolaan sampah dari Kelurahan Pejaten Barat di TPS Siaga belum dilakukan dengan maksimal, karena nilai reduksi sampah hanya sebesar 27.77%. Hal ini menyebabkan timbulan sampah yang diangkut ke TPST Bantar Gebang mencapai 72.32% atau 2,511.768 kg per hari. Apabila sampah anorganik dipilah secara maksimal, dan sampah organik direduksi menggunakan maggot BSF dan pengomposan, maka nilai potensi reduksi sampah dapat mencapai 84.37% atau 2,933.805 kg per hari. Jumlah timbulan sampah yang tereduksi ke TPST Bantar Gebang mencapai 56.6% atau 1,968.205 kg per hari.

Waste generation in South Jakarta City is up to 1,937.54 tons per day in 2021. The average waste generation continues to climb up to 17 tons every year. This problem is caused by poor waste management, such as what happened in the garbage collection site (TPS). Kelurahan Pejaten Barat has a TPS located behind Kelurahan Pejaten Barat Office called TPS Siaga. TPS Siaga accommodates waste from all RWs in Kelurahan Pejaten Barat and other locations. According to the SIPSN website, the waste entering TPS Siaga in 2022 is up to 19,130.36 tons per year. While the managed waste is only 222.7 tons per year, the difference between incoming and managed waste is very significant. TPS Siaga also intersects with rivers, when it rains heavily and/or overflows, floods occur. This research was conducted to study the management and processing of waste at TPS Siaga, measure the weight and volume of incoming waste generation, identify the composition of waste and the percentage of appropriate types of waste, and analyze the waste reduction potential that TPS Siaga can achieve. The research methods used in this study were observation and interviews to find out the waste management carried out at TPS Siaga, measurement of waste generation using the load-count analysis method, and composition identification using SNI 19-3964-1994. The results showed that waste generation that entered TPS Siaga from Kelurahan Pejaten Barat service area was 3,477,368 kg per day with a volume of 31,174 m3 and waste generation was 0,081 kg/person/day or 0,729 L/person/day. While the composition of the waste is dominated by food waste by 46.61%. The percentage composition of other waste is wood/branches/leaves of 1.16%, paper/cardboard 10.78%, plastic 18.17%, metal 1.05%, cloth/textile 6.38%, rubber/leather 0.23%, glass 1.69%, B3 0.71% and other waste 13.21%. Waste management from Kelurahan Pejaten Barat at TPS Siaga has not been carried out optimally, because the waste reduction value is only 27.77%. This causes the generation of waste transported to TPST Bantar Gebang up to 72.32% or 2,511.768 kg per day. If inorganic waste is optimally processed and organic waste is reduced using BSF maggot and composting, the potential value of waste reduction can be up to 84.37% or 2,933.805 kg per day. The amount of waste generated that is reduced to TPST Bantar Gebang is up to 56.6% or 1,968,205 kg per day."

"Tesis ini membahas strategi penduduk miskin kota, dalam hal ini pengangkut dan pengumpul sampah di Tempat Pembuangan Sampah Sementara (TPS), dalam memperoleh penghasilan, berdasarkan Konsep Urban Lifelihood dari Carole Rakodi. Konsep ini mengkaji modal-modal yang diperkenalkan oleh Rakodi sebagai Pentagon Aset, yaitu : modal manusia, modal fisik, modal alam, modal sosial dan modal keuangan. Penelitian ini dilakukan melalui penelitian kualitatif melalui metode advokasi dan parsipatoris. Hasilnya adalah bahwa untuk modal sosial dan manusia para pengangkut dan pemungut sampah cukup kuat, sedangkan untuk modal alam berupa keterbatasan lahan lemah, modal fisik berupa alat-alat produksi, rumah dan fasilitas lainnya juga lemah dan modal keuangan berupa layanan finansial juga lemah, sehingga para pengangkut dan pengumpul sampah ini terlibat dalam sistem patronisasi dan sistem ijon tarikan sampah. Diperlukan perencanaan sistem pengelolaan sampah permukiman yang menyeluruh yang juga melibatkan kaum miskin kota sebagai pelaku utama pengelola sampah permukiman. Juga aturan dan perundang-undangan mengenai mekanisme, pengoperasian dan formalisasi profesi para pengangkut dan pengumpul sampah yang semula informal menjadi formal, sehingga mereka dapat merasakan bantuan-bantuan dan layanan serta akses terhadap modal alam (tanah) fisik (alat produksi, rumah dan fasilitas lainnya), serta modal keuangan (pinjaman dan bantuan modal serta fasilitas tabungan untuk perencanaan masa depan).

This thesis is focus on urban poor strategy, whichs is the waste pickers and collectors at intermediate transfer facility of solid waste; as urban poor lifelihood strategy based on sustainable lifelihood approach for urban poor introduced by Carole Rakodi. This concept is analyze assets who introduced bay Rakodi, as Pentagon Assets, which is : Man, Physical, Natural, Social and Finance. The reasearch is based on qualitative reasearch through a method of advocacy and parsipatoris. The result is that to social capital and human beings for the waste pickers and collector are strong enough `, while for capital nature in the form of limited land is weak, Physical capital in the form of the means of production, the house and other facilities are also weak, and financial capital in the form of financial services is also weak, so this waste pickers and collectors comunitiy involves in the patronage and ijon system. Planning system required waste management comprehensive settlement and that involve the poor the city as a leading perpetrator of waste management settlement. And also the mechanism of the law, and formalisation of the the waste pickers and collectors profession who was initially informal be formal. So that they can sense the grants and services and access to capital nature (the ground) physical (a means of production , the house and other facilities) , financial and capital ( loans and capital assistance as well as saving facilities for planning future)."

"Secara garis besar tugas akhir ini adalah aplikasi nyata dari analisa discounted cash flow dan real options untuk memvaluasi proyek investasi IT untuk mendukung strategi e-commerce perusahaan. Investasi di bidang teknologi informasi (IT) sering terbebani dengan ketidakpastian yang dapat timbul, antara lain dari kompleksitasnya, atau dari situasi tak terduga, dan keadaan yang berubah-ubah. Untuk dapat dengan tepat mengantisipasi ketidakpastian, perusahaan perlu melakukan fleksibilitas terhadap keputusan investasi. Fleksibilitas terhadap keputusan investasi memungkinkan perusahaan untuk menghentikan atau meninggalkan investasi IT jika hasil investasi negatif, atau untuk memperpanjang dan memperluas jika hasil investasi positif. Analisa discounted cash flow adalah metode penilaian yang paling umum digunakan untuk investasi, dan real options adalah metode yang lebih akurat untuk melakukan valuasi investasi dengan tingkat ketidakpastian yang tinggi. Dalam thesis ini analisa real options menggunakan binomial lattice dan black scholes untuk valuasi proyek e-commerce.

In general this thesis is the real application of discounted cash flow analysis and real options to valuate an IT investment project to support company’s e-commerce strategy. Investments in information technology (IT) often bear great uncertainty which arises amongst others, from it’s complexity or from unpredictable situation, changing of circumstances. To be able to appropriately respond to uncertain developments, company need to exercise managerial flexibility. Managerial flexibility enables company to pause or abandon an IT investment in case of a negative development result, or to extend and expand in case of a positive development result. Discounted cash flow analysis is the most common valuation method used for investment, and real options is the most appropriate method to valuate an investment with high uncertainty. In this thesis real options analysis uses binomial lattice and black scholes to valuate e-commerce project."

"Jakarta adalah Ibu Kota Republik Indonesia dengan jumlah penduduk mencapai lebih dari 10 juta jiwa pada tahun 2011, dengan jumlah limbah padat yang dihasilkan mencapai 6.594,72 ton/hari (2.487,61 m3/hari). Salah satu elemen pengelolaan sampah di Jakarta adalah Tempat Penampungan Sampah Sementara, yang berfungsi sebagai lokasi penampungan dan pemilahan sampah yang dapat didaur ulang. TPS merupakan salah satu potensi sumber bioaerosol di udara. Selain proses degradasi sampah organik secara alami, teknis operasional pengelolaan sampah juga turut berperan terhadap tingginya konsentrasi bioaerosol di TPS. Analisis dalam penelitian ini dilakukan berdasarkan prinsip statistik korelasi bivariat dan multivariat. Berdasarkan hasil analisis, aktivitas penampungan, pemilahan, dan pengangkutan sampah merupakan aktivitas utama yang mempengaruhi konsentrasi bioaerosol. Selain itu, parameter meteorologis (temperatur udara, kelembaban udara, dan kecepatan angin) juga berperan cukup besar terhadap pertumbuhan dan persebaran bioaerosol di udara. Oleh sebab itu, diperlukan sebuah strategi pengendalian kualitas udara mikrobiologis di dalam maupun luar area TPS.

Jakarta is the capital of Indonesia with a population more than 10 million in 2011, that the amount of waste generated is approximately 6,594.72 tons/day (2,487.61 m3/days). In Jakarta, one element of solid waste management system is a transfer station. In Indonesia, transfer station handle solid waste that can be recycled and reused informally. Transfer station is a potential source of bioaerosol contaminants in the air. Besides the natural organic waste decomposition, operational techniques also gave a contribution to the high bioaerosol concentration at transfer station. The analysis was conducted based on bivariate and multivariate correlation statistics. Based on the analysis, collecting, sorting, and transporting are the main activities that affect bioaeorosol concentration. Moreover, meteorological parameters (air temperature, humidity, and wind velocity) also have a main role in growth and spread of bioaerosol to the ambient air. Consequently, it requires a strategy to control microbial air quality inside and outside the transfer station."

"Timbulan sampah di Jakarta adalah sebesar 6356,88 ton/hari pada tahun 2013. Harus dilakukan pengolahan sampah untuk menangani masalah tersebut. Salah satu caranya adalah dengan mentransformasi sampah menjadi energi, yaitu menjadi refuse derived fuel (RDF). Penelitian ini dilakukan di TPS Meruya Utara untuk menguji potensi sampah di TPS tersebut untuk dijadikan RDF. Berat timbulan sampah dan komposisi sampah di TPS Meruya Utara diteliti pula untuk menjadi pertimbangan dalam menyusun sampel RDF yang nantinya akan diuji potensinya. Sampel RDF dibentuk dari 45% sampah plastik, 25% sampah kertas, 15% sampah organik yang sudah dikeringkan secara aerobic selama 3 hari, dan masing-masing 5% sampah kayu, kain, dan karet. Potensi sampah tersebut dapat diuji dari berbagai parameter. Parameter yang diuji di dalam penelitian ini adalah nilai kalor, kadar air, kadar volatil, kadar abu, dan kadar klorin. Dari penelitian ini didapatkan nilai kalor sampel adalah 16,69 MJ/kg, kadar air sebesar 18,14%, kadar volatile sebesar 81,15%, kadar abu sebesar 11,83%, dan kadar klorin 0,01%.

"Tesis ini membahas tentang penggunaan Treatment Planning System (TPS) PRISM pada kasus kanker payudara menggunakan unit terapi Elekta di RSPAD Gatot Soebroto. Berkas elektron biasanya digunakan setelah pembedahan untuk pengobatan kanker payudara sebagai dosis tambahan. Pengukuran dosis dengan energi 8 MeV dan 10 MeV serta lapangan aplikator 6 x 6 cm2, 10 x 10 cm2, 14 x 14 cm2 dan 20 x 20 cm2 disimulasikan sebagai beam data pada PRISM. Beam data unit terapi SL20B merupakan bawaan pada piranti lunak PRISM yang akan dijadikan sebagai acuan kalkulasi. Dosis pada water phantom, inhomogenity phantom dan hasil simulasi CT Scan pasien kanker payudara dianalisis secara 1D berupa PDD, 2D berupa kurva isodosis dan 3D berupa Dose Volume Histogram. Distribusi dosis yang dikalkulasi dengan menggunakan TPS PRISM berbeda dengan hasil TPS ISIS. Hal ini karena adanya koreksi dari densitas jaringan (inhomogenitas) pada TPS PRISM sedangkan pada TPS ISIS tidak memperhitungkan hal tersebut. Beberapa deviasi distribusi dosis bernilai sangat besar antara TPS ISIS dan TPS PRISM. Deviasi melebihi 5% terjadi saat energi 8 MeV mulai dari kedalaman 2.3 cm dan 10 MeV mulai dari kedalaman 2.8 cm.

This thesis discusses about the utilization of PRISM Treatment Planning System (TPS) in the case of breast cancer using Elekta therapy unit at RSPAD Gatot Soebroto. Treatment option by using electron beam is always done after surgery as booster doses. Dose measurements with linac energy 8 MeV and 10 MeV and field sizes 6 x 6 cm2, 10 x 10 cm2, 14 x 14 cm2 and 20 x 20 cm2 were simulated as beam data on PRISM. Therapy unit SL20B beam data are innate in software PRISM that will be used as reference calculations. Doses on water phantom, inhomogenity phantom and the CT scan simulation for breast cancer patient were analyzed in form of PDD for 1D, isodosis curve for 2D and Dose Volume Histogram for 3D. The result from PRISM TPS and ISIS TPS are different because the correction factors of inhomogenity are not included in ISIS TPS. Some deviations of dose distribution from TPS ISIS and TPS PRISM are very high. Deviation larger than 5% started from 2.3 cm depth for 8 MeV and 2.8 cm for 10 MeV."

"[ABSTRAKPertumbuhan penduduk, pertumbuhan ekonomi dan urbanisasi di kota- kota besardi negara berkembang seperti Jakarta menyebabkan timbulan/generasi sampahsemakin meningkat. Sementara itu kapasitas TPA semakin menurun. Untukmengatasi permasalahan tersebut diperlukan upaya pengurangan sampah sejakdari sumbernya. TPS 3R dapat mengurangi volume sampah yang diangkut dandibuang ke TPA melalui pengomposan dan daur ulang pada skala kawasan.Namun demikian TPS 3R sangat mengandalkan peran serta masyarakat dalambentuk retribusi sampah dan pemilahan sampah sejak dari sumbernya. MetodeChoice Modeling (CM) dan Contingent Valuation (CV) digunakan untukmengetahui WTP masyarakat atas beragam pilihan layanan sampah berbasis 3R.CM digunakan untuk mengestimasi harga implisit tiap atribut layanan sepertiaroma TPS, pemilahan dan frekuensi pengumpulan sampah. Hasil CMmenunjukkan pemilahan sampah dari sumber masih merupakan beban bagi rumahtangga sedangkan aroma TPS yang semakin tidak bau dan pemilahan sampah diTPS menambah utilitas rumah tangga. Secara keseluruhan rumah tangga ternyatamemberikan penilaian yang cukup tinggi pada layanan manajemen sampahberbasis 3R. Dengan membandingkan potensi pendapatan dengan biaya layananmanajemen sampah tiap skenario, ditemukan bahwa tingkat cost recovery layananmanajemen sampah ramah lingkungan/TPS 3R lebih tinggi dibandingkan layanankonvensional. Dengan adanya tingkat cost recovery yang lebih tinggi dansejumlah eksternalitas positif yang dapat diperoleh, tidak ada alasan bagi pemdauntuk tidak mendukung layanan manajemen sampah berbasis 3R.

ABSTRACTPopulation,economic growth and urbanization in big cities in developing countrieslike Jakarta cause proliferating growth in solid waste generation. Meanwhilelandfill capacity is diminishing. To overcome this problem, efforts to reducewaste from the source are needed. Solid waste intermediate treatment facilitiesbased on 3R principles (TPS 3R) can reduce waste which must be transported anddisposed through communal composting and recycling.
