KESAKSIAN ANAK PADA PENGADILAN DALAM PEMBUKTIAN PERKARA PIDANA MENURUT UNDANG-UNDANG NO. 11 TAHUN 2012 TENTANG SISTEM PERADILAN PIDANA ANAK

Tujuan dilakukannya penelitian ini adalah untuk mengetahui bagaiamana pengaturan perlindungan hukum terhadap saksi anak dalam perkara pidana menurut Undang-Undang Nomor 11 Tahun 2012 Tentang Sistem Peradilan Pidana Anak dan bagaimana kekuatan pembuktian keterangan saksi anak di bawah Umur. Dengan menggunakan metode penelitian yuridis normatif, disimpulkan: 1. Perlindungan hukum terhadap saksi anak tindak pidana menurut sistem peradilan pidana menegaskan anak berhak atas semua perlindungan dan hak yang diatur dalam ketentuan peraturan perundang-undangan, seperti upaya rehabilitasi medis dan rehabilitasi sosial, baik di dalam lembaga maupun di luar lembaga. Jaminan keselamatan, baik fisik, mental, maupun social dan kemudahan dalam mendapatkan informasi mengenai perkembangan perkara. Hak Saksi Anak akan diatur dengan Peraturan Presiden dan berdasarkan pertimbangan atau saran Pembimbing Kemasyarakatan, Pekerja Sosial Profesional atau Tenaga Kesejahteraan Sosial atau Penyidik dapat merujuk Anak Saksi ke instansi atau lembaga yang menangani pelindungan anak atau lembaga kesejahteraan social anak. Saksi anak tindak pidana yang memerlukan dapat memperoleh pelindungan dari lembaga yang menangani pelindungan saksi dan korban atau rumah perlindungan sosial sesuai dengan ketentuan peraturan perundang-undangan yang berlaku. 2.Keterangan kekuatan pembuktian saksi anak di bawah umur tidak mempunyai nilai sebagai alat bukti, oleh sebab itu tidak mempunyai kekuatan pembuktian akan tetapi dapat dipakai sebagai petunjuk atau tambahan alat bukti yang sah lainnya ataupun menambah keyakinan hakim.Kata kunci: Kesaksian Anak, Pengadilan, Pembuktian, Perkara Pidan

James Baldwin\u27s Soundscape and Grain of the Racialized Body

I will investigate the language around, and in direct relation to, the musicality of James Baldwin’s work. The interdependence of music and literature compose the majority, if not all, of his literary corpus. However, at some point both art forms bifurcate and we are confronted by the difficulties of writing about music and sound, and about music in text. I confront Roland Barthes’s disdain for the adjective and his theory of the “Grain of the Voice” in order to argue that attention to Black expressive musical narrative forms make audible and allow readers to witness to the grain of the Black body in James Baldwin’s work. I will frame the music with the assistance of a seminal history of Jazz and Blues music by Amiri Baraka. I will then push and further complicate my argument by focusing on the Sonic Color Line as theorized by Jennifer Stoever. Stoever offers the “Embodied Ear” and “Listening Ear” as means to describing the racialized sound filters that I would like readers to be aware of when “listening” to the music performed in James Baldwin’s short stories, plays, and novels. Some of the works I examine include: “Sonny’s Blues”, “Going to Meet the Man”, Just Above my Head, and Another Country. I will also reference one of Baldwin’s theoretical works, The Fire Next Time

Development of sample preparation and chromatographic mass spectrometric techniques for determination of selected organic pollutants in wastewater

Abstract : In the recent past, there has been a great concern on the ever-increasing emergence of organic contaminants in the various environmental compartments, that pose great health concerns to humans and aquatic life. These organic pollutants have been ubiquitous in the environment for decades, however, they were not identifiable until the emergence of new and advanced analytical technologies. Therefore, the main objective of this study was to develop robust and efficient analytical and modelling techniques, for the extraction and analysis of selected multiclass organic contaminants from wastewater samples. This is because their analytical determination is very challenging due to their occurrence in trace levels (ng L-1 to μg L-1) in the environment. The analytical techniques comprise of optimization of both the sample preparation procedures and instrumental analysis for detection and quantification. Solid phase extraction (SPE), dispersive liquid-liquid microextraction (DLLME) and ultrasonic-assisted magnetic solid phase dispersive extraction (UA-MSPDE) were the selected sample preparation techniques used for the extraction and preconcentration of methylparaben, ethylparaben, propylparaben, ethoprofos, parathion methyl, azinphos methyl and chlorpyrifos in water samples. This was followed by instrumental analysis for their detection and quantification using liquid chromatography tandem mass spectrometry (LC-MS/MS). The developed analytical techniques were applied in real environmental samples obtained from different water treatment stages of a local wastewater treatment plant in Gauteng province, South Africa. Experimental factors that had an influence on the analytical response in terms on highest percentage recoveries were optimized using both univariate (one factor a time) and multivariate approach for all the experiments in this study. Multivariate optimization was accomplished using Statistica and Minitab software. The performance characteristics of the LC-MS/MS facilitated the determination of these organic contaminants at trace levels. Multiple reaction monitoring mode (MRM) was used for specific and sensitive targeted analysis, where the quadrupole analyzers were set at multiple ion frequencies for the specific analytes under investigation together with their product fragment ions. MRM is ideally suitable for trace level analysis of complex mixtures. Oasis HLB cartridges were found to be suitable for extraction of parabens giving satisfactory results. Vortex assisted dispersive liquid-liquid microextraction (VA-DLLME) was used for the extraction and enrichment of organophosphorus pesticides in wastewater samples. Selection of the appropriate organic solvent (extractant and disperser solvents) used for this method was of utmost importance and was performed using univariate optimization. v The results revealed chloroform to be the most suitable extractant solvent while acetone was the optimum disperser solvent. This was followed by the chemometric optimization of the independent variables that significantly affect the outcome of the analytical response. The organophosphorus compounds that were extracted in wastewater samples using this technique with satisfactory results were ethoprofos, parathion methyl and azinphos methyl. Also, a novel method was developed for the extraction and preconcentration of multiclass organic compounds (parabens and organophosphorus pesticides) using synthesized pristine carbon nanodots (CNDs) applied as SPE adsorbent. A comparison between the synthesized CNDs and commercial based SPE sorbent was analyzed. Two-level factorial design and response surface methodology based on central composite design were used for multivariate optimization of the experimental variables. Furthermore, the CNDs were also functionalized with magnetite. The magnetic CNDs were applied for the development of magnetic solid phase dispersive extraction method with ultrasonic dispersion for the simultaneous extraction of chlorpyrifos and triclosan in environmental water samples. This method offered a very rapid and simple extraction and preconcentration of these organic contaminants with satisfactory results.Ph.D. (Chemistry
