Analysis of Hydroquinone in Whitening Cream Sold in Sukaramai Markets and in Ecommerce Using The Ultraviolet Spectrophotometric Method
No full textBackground: Whitening cream is a type of cosmetic that contains active substances that can suppress or inhibit the formation of melanin, thereby giving the skin a whiter color. Hydroquinone is an active compound that is often added to whitening creams. Hydroquinone is a chemical compound in the form of white, needle-shaped crystals, odorless, with the chemical formula C6H4(OH)2 and the chemical name 1,4-benzendiol or quinol, and undergoes oxidation in light and air. If the whitening cream contains the chemical hydroquinone, it can cause damage to the skin such as irritation, allergies, brain damage, and cancer.
Objective: This research aims to determine whether the levels of hydroquinone in facial whitening cream sold at Sukaramai Market and in e-commerce can be determined using ultraviolet spectrophotometry and in accordance with those determined by BPOM.
Methods: Facial whitening cream samples were purchased at Sukaramai Market and at the e-commerce Shoppe randomly. Next, the samples were tasted qualitatively using color reagents and quantitatively using ultraviolet spectrophotometry at a wavelength of 293 nm.
Results: The results of research on qualitative analysis using FeCl3 and 96 % Ethanol reagents showed that there was one sample, namely sample A, which was positive for containing hydroquinone, where as when using phloroglucin and NaOH reagents there were 5 samples, namely B, C, D, E, F which were positive for containing hydroquinone. From the analysis carried out, the hydroquinone content in sample A was obtained; 0,648 %, B; 0,74 %, C; 0,901 %, D; 1,091 %, E; 1,363 %, and F; 0,907 %.
Conclusion: Based on the results obtained, it shows that the ultraviolet spectrophotometry method can be used to determine hydroquinone levels in whitening cream. The hydroquinone content contained in all samples did not meet the requirements set by BPOM.73 PagesKertas Karya Diplom
Digitale Editionsformen. Zum Umgang mit der Überlieferung unter den Bedingungen des Medienwandels. Teil 1: Das typografische Erbe.[Preprint-Fassung]
No full textDigitale Editionsformen müssen auf dem Methodenstand der gedruckten Editionen aufbauen. Hier sind der Lachmannsche Ansatz der Textrekonstruktion und die Verfahren der historisch-kritischen Ausgabe im Laufe der Zeit zwar dominant geworden, aber nicht alternativlos geblieben. Die Kritik an diesen Methoden ist so alt wie diese selbst, und viele andere Schulen haben sich neben ihnen etabliert. Die verschiedenen Ansätze lassen sich als Produkt ihrer Zeit und als Funktion bestimmter theoretischer Grundbegriffe und Grundannahmen beschreiben. Vor allem aber sind sie nicht nur historisch und theoretisch, sondern immer auch "technisch relativ", weil Typografie und Druckkultur unsere Theorien vom Text und unsere Methoden der Edition beeinflussen. Ein Verständnis dieser Abhängigkeit unserer scheinbar "natürlichen" Editionsvorstellungen von einer bestimmten Technik ist ein wichtiger Ausgangspunkt für die Entwicklung neuer Editionsformen

Sketsa Karya Ari Nur Utami: Arsitektur Urban dalam Perspektif Ekokritisisme
No full textKota adalah ruang kompleks bagi siapa pun yang berada di dalamnya. Saat ini, penghuni ruang kota terancam oleh menurunnya kualitas ekologis kota akibat pembangunan gedung, berbagai fasilitas. dan infrastruktur kota yang masif. Salah satu novel yang memotret eksploitasi ekologi kota tersebut adalah Sketsa karya Ari Nur Utami. Sebagai novel berlatar belakang arsitektur, Sketsa menceritakan pembangunan gedung di Jakarta oleh pengembang bernama PT Semesta Sentosa. Menggunakan teori ekokritisisme, fokus diskusi dalam artikel ini adalah cara penulis memasukkan nilai dan asumsi ekokritik dalam arsitektur urban di novel Sketsa. Tulisan ini bertujuan untuk menguraikan dominasi pandangan antroposentris individu terhadap alam. Melalui metode kualitatifdeskriptif dengan melakukan closereading, hasil pembahasan menunjukkan bahwa pembangunan di Jakarta dengan berbagai proyek arsitektur urbannya masih mengabaikan kelestarian lingkungan. Ketidakpedulian terhadap lingkungan ini dapat dilihat dari orientasi etis dan linguistik antroposentris yang dipilih demi mendapatkan keuntungan besar dalam bisnis properti di Jakarta.

Abstract: 
City is a space that contains complexities for anyone being part of it. Nowadays, people are threatened by the ecologically degrading city as the result of the massive development of buildings and other city’s facilities and infrastructures. A novel portraying the issues of ecological exploitation is Ari Nur Utami’s Sketsa. Being claimed as an architectural background novel, Sketsa portrays the development of buildings in Jakarta by a property developer named PT Semesta Sentosa. By applying ecocriticism theory, one point discussed in this article is how the author imputes certain ecocritical values and assumptions in presenting the urban architecture in Sketsa. The objective of this research is to elaborate the domination of anthropocentric perspective over nature. Through the qualitativedescriptive method, it is found that the development of Jakarta as an urban space is still far from ecocritical considerations. This can be seen from ethical orientation and anthropocentric linguistic chosen for the benefits of property business in Jakarta.
