Abstract

Production of the domestic tyre industries in 2019 reached 150,2 million units. With a five-year lifespan for car tire and two-year lifespan for motorcycle tire, it is estimated that millions of used tires are waste and have the potential to damage the environment. Therefore some effort is needed to recycle and convert used tyres to be more useful product. Pyrolysis (catalytic cracking), that is thermal treatment method, can degrade polystyrene which is the constituent material of tyres back into hyrocarbon compounds. This research was conducted to see the effect of temperature and catalyst percentage on liquid fuel that have obtained by using two type of catalysts. From this study it is known that entire samples meet SNI 8220:2017 for diesel fuel 48 where the sample with - Al2O3 catalyst at a temperature of 350 °C gives the best result with density of 0.83204 gram/cm3, viscosity of 3.41908 cSt, and flash point of 62 °C.

Abstract

Sebuah wilayah bernama Kembang Kuning di Surabaya mulanya dikenal sebagai daerah sakral karena di dalamnya terdapat Masjid dan Pondok Pesantren yang dibangun oleh Sunan Ampel. Di sisi lain, Kembang Kuning turut dikenal sebagai wilayah pemakaman bagi pemeluk agama Kristen dan Katolik. Namun, seiring berjalannya waktu terdapat anggapan “negatif” ketika menyebut nama Kembang Kuning, yang kini disebut sebagai salah satu tempat prostitusi bagi kalangan waria. Untuk itu, penelitian ini disusun dengan tujuan menganalisis produksi ruang pada makam Kembang Kuning sebagai tempat lokalisasi waria Surabaya. Metode penelitian yang digunakan ialah kualitatif yang dibarengi dengan penggunaan teori ruang atau space yang disampaikan oleh Lefebvre. Peneliti turut melakukan wawancara dengan waria dan masyarakat sekitar Kembang Kuning. Hasil penelitian menunjukkan bahwa kehadiran Kembang Kuning sebagai sebuah wilayah telah menghasilkan “ruang” baru yang berbeda. Artinya, terjadi pergeseran makna akibat proses produksi-reproduksi, di mana sebelumnya Kembang Kuning dianggap sebagai wilayah sakral, tetapi kini dikenal sebagai daerah kumuh dan tempat prostitusi. Oleh sebab itu dapat disimpulkan bahwa representasi ruang atas Kembang Kuning telah berbeda dari masa ke masa. Tentu hal ini dilandasi oleh realita kemasyarakatan dan gejala sosial yang timbul, yang turut membentuk wilayah tersebut sebagai sebuah ruang yang tidak hampa hingga mewujudkan pemaknaan baru yang tidak sama. An area called Kembang Kuning in Surabaya was originally known as a sacred area because it contained a mosque and Islamic boarding school built by Sunan Ampel. Kembang Kuning is also known as a burial area for Christians and Catholics. However, as time went by, there was a "negative" perception of the area, which is now said to be a place of prostitution for transgender people. This research was prepared with the aim of analyzing the production of space at the Kembang Kuning tomb as a place for the localization of transgender women in Surabaya. The research method used is qualitative combined with the use of space theory presented by Lefebvre. Researchers also conducted interviews with shemale and the community around Kembang Kuning. The research results show that the presence of Kembang Kuning as an area has produced a new "space" related to the shift in meaning due to the production-reproduction process, where previously Kembang Kuning, which was known as a sacred area, is now referred to as a slum area and place of prostitution. Therefore, it can be concluded that the spatial representation of Kembang Kuning has been different from time to time. Of course, this is based on social realities and emerging social phenomena, which help shape the region as a space that is not empty and creates new, different meaningKeywords: kembang kuning, funerals, prostitution, shemale.

Abstract

Author Name Disambiguation (AND) is a problem that occurs when a set of publications contains ambiguous names of authors, i.e. the same author may appear with different names (synonyms) in other published papers, or author (authors) who may be different who may have the same name (homonym). In this final project, we will design a model with a Deep Neural Network (DNN) classifier. The dataset used in this final project uses primary data sourced from the Scopus website. This research focuses on integrating data from Indonesian authors. Parameters accuracy, sensitivity and precision are standard benchmarks to determine the performance of the method used to solve AND problems. The best DNN classification model achieves 99.9936% Accuracy, 93.1433% Sensitivity, 94.3733% Precision. Then for the highest performance measurement, the case of Non Synonym-Homonym (SH) has 99.9967% Accuracy, 96.7388% Sensitivity, and 97.5102% Precision.
