Optimasi Komposisi Galian Timbunan Sampah Sebagai Bahan Baku Refuse Derived Fuel (RDF) Di TPA Supit Urang
No full textTempat Pemrosesan Akhir (TPA) merupakan salah satu fasilitas yang harus ada di setiap kabupaten atau kota, tak terkecuali Kota Malang. Kota Malang memiliki satu buah TPA yaitu TPA Supit Urang yang telah beroperasi sejak tahun 1993. Berdasarkan data dari Sistem Informasi Pengelolaan Sampah Nasional (SIPSN), pada tahun 2023 timbulan sampah Kota Malang mengalami peningkatan sebesar 778,34 ton/hari. Menurut perhitungan secara kasar yang dilakukan penulis apabila timbulan sampah Kota Malang yang terus meningkat dan tidak tertangani dengan baik, maka umur aktif lahan TPA hanya tersisa 2 tahun lagi. Dikarenakan TPA ini, merupakan satu-satunya TPA yang ada di Kota Malang, maka akan dilakukan peneltian yang bertujuan untuk menentukan karakteristik dan komposisi sampah yang ada di TPA Supit Urang, menentukan komposisi yang optimal sebagai bahan baku RDF, dan menentukan estimasi potensi hasil lahan urug untuk meproduksi RDF di TPA Supit Urang.
Sampel yang digunakan untuk penelitian ini diambil pada 2 titik yang merepresentasikan umur 10-15 tahun pada zona 2 dan umur 15-25 tahun pada zona 1. Kedalaman galian sampel sedalam 2 meter. Kemudian sampel yang diambil sebanyak ±100 kg dan dilakukan pemilahan untuk mengetahui komposisinya. Sampel yang telah diambil dan dipilah, kemudian akan diujikan pada Laboratorium Limbah Padat dan B3 Departemen Teknik Lingkungan ITS. Parameter yang diujikan antara lain kadar air, kadar volatil, kadar abu, dan nilai kalor.
Hasil penelitian ini menunjukkan bahwa komposisi material gali pada lahan pasif TPA Supit Urang memiliki kompsosisi yang paling tinggi dimiliki oleh sampah berjenis plastik pada lahan pasif zona 1 sebesar 55,58% dan pada zona 2 sebesar 50,25%. Kemudian karakteristik pada lahan pasif TPA Supit Urang memiliki kadar air dengan rentang 53,38-68,10%; kadar volatil 38,69-74%; kadar abu 26-61,31%; dan nilai kalor 5,09-9,84 MJ/kg. Komposisi yang memiliki nilai kalor paling tinggi terdapat pada komposisi yang terdiri dari plastik, kain, dan karet dengan nilai kalor 18,73 MJ/kg-20,64 MJ/kg. Estimasi potensi ekonomi apabila bahan baku RDF pada TPA Supit Urang dijual dapat menghasilkan pendapatan sebesar Rp. 15.662.827.321,-. dan estimasi keuntungan bersih sebesar Rp. 1.185.812.756,-.

Final Processing Site is one of the facilities that must exist in every regency or city, and Malang City is no exception. Malang City has one landfill, namely Supit Urang Landfill, which has been operating since 1993. Based on data from the National Waste Management Information System (SIPSN), in 2023 Malang City's waste generation increased by 778.34 tons/day. According to rough calculations made by the author, if Malang City's waste generation continues to increase and is not handled properly, the active life of the landfill will only be 2 years left. Since this landfill is the only landfill in Malang City, a research will be conducted to determine the characteristics and composition of waste in Supit Urang Landfill, determine the optimal composition as RDF raw material, and determine the estimated potential yield of landfill to produce RDF in Supit Urang Landfill.
The samples used for this study were taken at 2 points representing ages 10-15 years in zone 2 and ages 15-25 years in zone 1. The depth of the sample excavation was 2 meters deep. Then the samples taken were ± 100 kg and sorted to determine their composition. Samples that have been taken and sorted, will then be tested at the ITS Environmental Engineering Department's Solid and Hazardous Waste Laboratory. The parameters tested include moisture content, volatile content, ash content, and calorific value.
The results of this study indicate that the composition of excavated material in the passive landfill Supit Urang has the highest composition owned by plastic waste in passive land zone 1 of 55.58% and in zone 2 of 50.25%. Then the characteristics of the Supit Urang landfill passive land have a moisture content with a range of 53.38-68.10%; volatile content 38.69-74%; ash content 26-61.31%; and a heating value of 5.09-9.84 MJ / kg. The composition that has the highest heating value is the composition consisting of plastic, cloth, and rubber with a heating value of 18.73 MJ/kg-20.64 MJ/kg. Estimated economic potential if RDF raw materials at Supit Urang Landfill are sold can generate revenue of Rp. 15,662,827,321, -. and estimated net profit of Rp. 1,185,812,756, -

Get PDFKekerasan seksual terhadap anak yang terjadi di provinsi Sulawesi Utara semakin meningkat terutama pada empat tahun terakhir. Sejak masuknya pandemi pada tahun 2020 di Sulawesi Utara, kasus kekerasan seksual terhadap anak pun semakin banyak terjadi. Sistem aturan mengenai tindak lanjut bagi anak korban kekerasan seksual pun harus dilakukan sesuai dengan protokol kesehatan Covid-19. Pandemi ini membuat adanya beberapa perubahan dalam penanganan korban kekerasan. Hal ini yang membuat penulis tertarik untuk melakukan analisis terhadap strukturasi implementasi kebijakan pemerintah terhadap anak korban kekerasan seksual sebelum dan selama pandemi di provinsi Sulawesi Utara. Adanya hukum internasional seperti Convention on the Rights of the Child 1989 (CRC) atau Konvensi Hak Anak dan juga Non-Governmental Organization (NGO) juga yang bekerjasama dengan pemerintah untuk menangani isu ini sangatlah membantu untuk meningkatkan perlindungan terhadap anak terutama untuk anak korban kekerasan seksual di Indonesia dan di Sulawesi Utara. Tujuan dilakukannya penelitian ini yaitu agar pembaca dapat lebih memahami bagaimana strukturasi cara pemerintah dalam menangani anak korban kekerasan seksual yang semakin meningkat pada masa pandemi ini. Penulis menggunakan konsep Strukturasi dari Anthony Giddens dan teori konstruktivisme oleh Alexander Wendt guna untuk menganalisis bagaimana konstruksi ide dalam suatu sistem mengenai isu kekerasan seksual terhadap anak.Sexual violence against children in North Sulawesi province has increased, especially in the last four years. Since the entry of the pandemic in 2020 in North Sulawesi, cases of sexual violence against children have also been increasing. The regulatory system regarding followup for child victims of sexual violence must also be carried out in accordance with the Covid19 health protocol. There are changes in the way of coping and there are still many people who do not understand the role of the government, making many victims who are just left alone and do not get justice. This makes the authors interested in conducting an analysis of the structuring of the implementation of government policies towards child victims of sexual violence before and during the pandemic in North Sulawesi province. The existence of international laws such as the 1989 Convention on the Rights of the Child (CRC) or the Convention on the Rights of the Child as well as Non-Governmental Organizations (NGOs) also working with the government to deal with this issue is very helpful to improve the protection of children, especially for children who are victims of sexual violence. in Indonesia and in North Sulawesi. The purpose of this research is so that readers can better understand how the government is structured in dealing with child victims of sexual violence, which is increasing during this pandemic. The author uses the concept of structuration by Anthony Giddens and constructivism theory by Alexander Wendt to analyze how ideas are constructed in a system regarding the issue of sexual violence against children
An original meaning of Si Tou Timou Tumou Tou in post-independence war Indonesia: A first-hand experience of Sam Ratulangi’s oldest daughter
Get PDFSitou timou tumou tou (ST4) has been a well-recognized philosophy adopted by the Minahasan people. During its development, it has become even more popular within the scope of education. ST4 was said to be first mentioned by the Minahasan national hero, Sam Ratulangi. The interpretations of ST4 have been abundant, mostly reciting the educational aspect: “a man lives to make other men humans.” However, a direct historical record on when and in what situation ST4 was first mentioned by Sam Ratulangi is not well known by the academia and general public. In fact, there has not been any written authoritative source about this manner. In this auto-narrative historical research, the authors took advantage of the direct experiential account of the oldest daughter of Sam Ratulangi (the second author) when ST4 was first said by Sam Ratulangi himself. This has revealed a novel, but rather the original intention of Sam Ratulangi when he first mentioned ST4 in the context of post-war Indonesia: “a man lives to live as a real man.
