"In this edited volume, scholars from Mumbai, Bengaluru, Jakarta, Cape Town, Sao Paulo and other cities of the global South explore the complex relationship between platformization and informality through a different lens. Drawing on extensive theoretical, quantitative and qualitative scholarship, they provide both a useful overview and insights into the lived realities of gig work for platforms covering a range of skills, working conditions, and forms of algorithmic management. Platform work has attracted considerable attention from scholars in the global North, who have tended to view it as a form of casualisation of work that was previously regulated. But what about the global South, where most employment, especially that of women and migrant workers was historically already informal?
Beyond a focus on livelihoods, employment, and work, the authors show how labour platforms take on powers that bring about broader impacts, including those affecting identity and personal wellbeing. They also illustrate the impact of platformization on the governance of affected sectors by public agencies, thus affecting political power, and how public data infrastructures contribute to further platformization. The purpose of this pioneering work is to lay bare these interactions to then rebuild our understanding of platformization and its social, political, cultural and economic impacts. Its insights are attentive to gender and ethnic differences, as well as geographical ones."

"Jakarta, sebagai kota bekas penjajahan, memiliki banyak wilayah dan bangunan-bangunan bersejarah. Salah satu area bersejarah tersebut adalah Glodok yang merupakan wilayah Pecinaan atau China Town. Wilayah tersebut menyimpan sejarah panjang bagi warga Tiong Kok yang dulunya bermigrasi dari wilayah Tiong Kok Selatan. Di awal abad-19, ada seorang Mayor Cina-Batavia bernama Souw Thian Pie yang membangun sebuah hunian tradisional China bernama siheyuan di Jalan Perniagaan Raya, Glodok. Dewasa ini, banyak hunian tradisional China di Glodok, termasuk siheyuan keluarga Souw, telah mengalami transformasi dan adaptasi sebagai akibat dari modernisasi.
Penulisan skripsi ini bertujuan untuk mengidentifikasi siapa, apa, kapan, mengapa, dan bagaimana transformasi tersebut telah terjadi di siheyuan keluarga Souw dan kemungkinan kaitannya dengan modernisasi. Untuk mencapai tujuan tersebut, sebuah observasi langsung dilakukan di siheyuan keluarga Souw yang masih bertahan selama hampir dua abad. Kebanyakan informasi terkait studi kasus merupakan hasil wawancara dengan Bapak Yong Yong yang merupakan salah satu kepala keluarga dari generasi ke lima dan keturunan langsung dari Souw Thian Pie. Analisis dari studi kasus menyimpulkan bahwa modernisasi berperan besar dalam menyebabkan terjadinya transformasi berupa rotasi dari selatan ke utara pada akses utama dan hilangnya sayap barat pada siheyuan keluarga Souw.

As a former colonial city, there were many historical sites and buildings in Jakarta. One of the historical sites in Jakarta is Glodok, which is also called ?China Town? or ?Pecinaan Area?. The area has a long history for Chinese migrants, who mostly came from Southern China. In the early 19th century, there was a Chinese mayor, Souw Thian Pie, who built a ?siheyuan? (traditional Chinese dwelling) at Jalan Perniagaan Raya in Glodok. Today, many traditional Chinese dwellings in Glodok, including Souw family siheyuan, have experienced transformation and adaptation due to modernism.
This undergraduate thesis aims to find who, what, when, why, and how transformation has occurred in Souw family siheyuan and its possible relations with modernism. To achieve this, an observation was held directly in the Souw family siheyuan that has survived for almost two centuries. Most of the information regarding the case study was obtained from the interview with Mr. Yong Yong, who is one of the 5th generations head families and a direct descendant of Souw Thian Pie. Analysis of the siheyuan concludes that modernism played significant role in causing transformation of the main entrance to be rotated from south to north and elimination of the west wing.

"Pada era Industri 4.0, PT X dituntut untuk beradaptasi dengan perubahan teknologi sehingga mampu bersaing dengan kompetitor dan mempertahankan keberlangsungan bisnis. Oleh karena itu, perlu adanya transformasi digital sebagai langkah strategis untuk beradaptasi terhadap perubahan lingkungan dan menjawab tantangan pasar di era digital. Tujuan penelitian ini adalah untuk mengetahui peran moderasi employees’ affective commitment to change dalam hubungan antara digital leadership dan transformasi digital. Penelitian ini menggunakan desain non-eksperimen cross-sectional melalui survei online dengan teknik convenience sampling untuk mendapatkan partisipan. Jumlah partisipan sebanyak 335 orang karyawan tetap PT X dengan masa kerja minimal satu tahun dan memiliki atasan langsung. Data dianalisis menggunakan analisis regresi moderasi Hayes Macro PROCESS model 1. Hasil penelitian menunjukkan bahwa employees’ affective commitment to change memoderasi positif hubungan antara digital leadership dan transformasi digital (b = 0,160, 95% CI [0,050, 0,270], t = 2,849, p < 0,01). Temuan ini mengungkapkan bahwa dalam konteks change management, keberhasilan transformasi digital dapat dicapai apabila terdapat interaksi antara digital leadership sebagai faktor transformasional dan employees’ affective commitment to change sebagai faktor transaksional pada PT X. Hasil penelitian ini dapat menjadi pedoman PT X untuk lebih fokus terhadap upaya peningkatan employees’ affective commitment to change dan pengembangan digital leadership para pemimpin dalam upaya mewujudkan keberhasilan dan keberlanjutan transformasi digital.

In the era of Industry 4.0, PT X is required to adapt to technological changes to remain competitive with its competitor and maintain its business continuity. Therefore, digital transformation is essential as a strategic step to adapt to environmental changes and address market challenges in the digital era. The purpose of this study is to determine the moderating role of employees' affective commitment to change in the relationship between digital leadership and digital transformation. This study uses a cross-sectional non-experimental design through an online survey with convenience sampling technique. The number of participants was 335 permanent employees of PT X with at least one year of work experience and having supervisor. The data were analysed using Hayes Macro PROCESS model 1 moderation regression analysis. The results showed that employees' affective commitment to change has a positive moderating effect on the relationship between digital leadership and digital transformation digital (b = 0,160, 95% CI [0,050, 0,270], t = 2,849, p < 0,01). These findings reveal that in the context of change management, the success of digital transformation at PT X can be achieved through the interaction between digital leadership as a transformational factor and employees' affective commitment to change as a transactional factor. This study provides valuable insights for organizations to focus on enhancing employees’ affective commitment to change and developing digital leadership among leaders to achieve successful and sustainable digital transformation."

"Watermarking merupakan teknik untuk menyisipkan informasi yang disebut watermark kedalam suatu data digital lainnya, tetapi tidak diketahui kehadirannya oleh indera manusia. Sehingga data tersebut dapat didistribusikan tanpa adanya kecurigaan terdapat tanda rahasia didalamnya. Teknik watermarking dibagi menjadi dua, yaitu teknik watermarking yang bekerja pada domain spasial (domain waktu) dan teknik watermarking yang bekerja pada domain transformasi (domain frekuensi). Watermarking yang bekerja dalam domain spasial langsung merubah nilai piksel pada citra atau gambar aslinya. Watermarking pada domain transformasi diperoleh dengan melakukan transformasi image menjadi domain frekuensi. Watermarking dalam domain transformasi seperti Discrete Fourier Transform (DFT), Discrete Wavelet Transform (DWT), Discrete Cosine Transform (DCT) atau Discrete Laguerre Transform (DLT) memiliki lebih banyak keuntungan dan kinerja yang lebih baik daripada teknik yang bekerja dalam domain spasial. Pada makalah ini, dilakukan analisis mengenai DLT berdasarkan ukuran matriks dan membandingkannya dengan DCT.

Watermarking is a technique to insert information called watermark into any other digital data, which is the presence is unknown by human senses. So the data can be distributed without any suspicions there are a secret message in it. There are two techniques in watermarking, spatial domain and frequency or transformation domain. Spatial domain watermarking technique works by changing the original image or picture pixels value into the new pixels value. Frequency domain watermarking technique works by transforming the original image into frequency domain. Frequency domain watermarking techniques such as Discrete Fourier Transform (DFT), Discrete Wavelet Transform (DWT), Discrete Cosine Transform (DCT) or Discrete Laguerre Transform (DLT) have a better performance and advantages than spatial domain watermarking technique. This paper analysed Discrete Laguerre Transform (DLT) by its matrix size and compared it with DCT."
