Formulasi Gel Mukus Ikan Sidat (Anguilla Bicolor) Sebagai Kandidat Penyembuh Luka BakarLuka bakar bisa di sebabkan oleh panas, arus listrik, bahan kimia dan petir yang mengenai kulit, mukosa atau jaringan yang lebih dalam. Salah satu bentuk sediaan obat yang baik untuk menyembuhkan luka barkar adalah gel. Penelitian ini bertujuan untuk Mengetahui Proses Pembuatan Sediaan Gel luka bakar dari mukus ikan sidat dan Uji organoleptis, stabilitas, homogenitas, pH, visikositas dan iritasi gel mukus ikan sidat. Untuk menghasilkan mukus ikan sidat dilakukan dengan cara perendaman ikan dengan menggunakan es batu, kemudian lendir yang terdapat pada kulit ikan diambil. Lendir ikan sidat diformulasikan dalam bentuk sediaan gel dengan konsentrasi CMC 6, 8, dan 10 gram. Evaluasi sediaan meliputi uji organoleptis, stabilitas, homogenitas, pH, daya sebar, viskositas dan uji terhadap iritasi kulit. Kenampakan sediaan gel dari 3 sediaan memiliki bentuk semi padat, terasa dingin saat di oleskan ke kulit serta memiliki homogenitas yang baik. pH dari 3 sediaan yaitu 7. Dari sediaan yang di...

Eel (Anguilla spp.) is a fish that has a perfect tail, dorsal and anal fins. The eel's fins are equipped with visible soft fingers and the three fins are connected to each other, starting from the back to the tail and ending at the abdomen of the body. The thing that stands out from the eel is the presence of a pair of pectoral fins that are visible on both sides of the body which is located behind the head so that it is suspected that the fins are the ears. Identification of eel species is very important for the management of a resource. The ADL/% TL key character comparison is one way of identifying the types of eels that can be applied. Sampling and measurement of water parameters were carried out on 23 to 25 August 2020. From the research results obtained 1 type of eel, namely Anguilla bicolor (ADL/% TL = -0.37 to 4.76) where the eel entered the Yellow ell phase. This Anguilla bicolor eel likes slow-flowing waters (lentic waters) and sandy mud. Overall the water parameters i...

Sidat memiliki nilai ekonomis tinggi dan permintaan global semakin meningkat. Salah satu daerah di Pulau Jawa yang berbatasan langsung dengan Samudera Hindia dan menjadi jalur ruaya larva sidat (glass eel) adalah Kabupaten Purworejo. Namun hingga saat ini, belum ada laporan ilmiah mengenai keberadaan sumberdaya sidat di Kabupaten Purworejo. Penelitian ini bertujuan untuk mengetahui potensi sidat ditinjau dari sebaran tangkapan ikan sidat, jumlah hasil tangkapan di alam dan variasi ukuran. Pemetaan dilakukan dengan 2 tahap yakni menentukan beberapa lokasi sungai yang terdapat hasil tangkapan sidat berdasarkan informasi masyarakat dan pengambilan sampel sidat pada malam hari saat fase bulan gelap 28-29 kalender lunar Maret hingga Mei 2015. Alat tangkap yang digunakan anco dan bubu. Pengukuran parameter fisika kimia perairan dilakukan bersamaan pada saat sampling sampel sidat meliputi suhu, salinitas, pH, oksigen terlarut, nitrat dan fosfat. Hasil penelitian menunjukkan terdapat 3 loka...

This thesis discusses the various ways in which algorithmic pricing harms consumers, and explores the normative implications of these claims in terms of law, design, and policy. Algorithmic pricing refers to the use of data analytics in implementing either price discrimination or dynamic pricing in consumer-to-business online commerce. Algorithmic pricing is a relatively new phenomenon that has emerged with the ability of digital technology to exploit an unprecedented amount of personal data in order to guess the consumer’s reserve price. The general consensus is that algorithmic personalised pricing down to the individual is not yet technically feasible, but is imminent (Seele et al.). Meanwhile, online platforms can already use anonymous and pseudonymous data to finesse third-degree price discrimination–that is, to personalise prices for specific groups. In this way, pricing algorithms enable firms to engage in price discrimination, which is when the same product is sold to different consumers for different prices. Price discrimination is neither exclusive to internet commerce, nor is it necessarily morally problematic. Many forms of price discrimination and algorithmic pricing are legal and morally permissible from welfarist and egalitarian perspectives alike, due to their positive contribution to social welfare. I bring together all the disparate concerns about algorithmic pricing—exploitation, manipulation, discrimination, and collusion—into a unified normative analysis of the technology’s effect on consumers and the market. I apply a consequentialist harm-based moral theory to the appraisal of algorithmic pricing. I ground this theory in a naturalist metaethics, in order to show how common-sense moral intuitions based on empirical observation can be systematised to provide normative insights into contemporary policy debates. The first six chapters are unified by a concern with the ways in which some forms of algorithmic pricing threaten resource equality and political equality. I begin in the first chapter by presenting a mixed subjective-objective theory of wellbeing, whose causally necessary (but insufficient) conditions include political and resource equality. It follows that when algorithmic pricing increases inequality, it threatens aggregate wellbeing and is pro tanto wrong. In Chapters 2 to 5 of this thesis, I develop normative theories of exploitation, manipulation, discrimination, and collusion to clarify why some instances of algorithmic pricing are pro tanto wrong. In Chapter 2, I refer to regressive dynamic pricing as ‘dynamic exploitation’ and provide a formula for determining when dynamic pricing is exploitative or when price gouging—charging prices well above normal market rates during crises—is permissible. The use of big data by online retailers to predict and manipulate consumer behaviour is a phenomenon that I discuss in Chapter 3 and call ‘algorithmic nudge’. In Chapter 4 I provide a theory of discrimination that articulates what is wrong about wrongful discrimination, and apply it to this phenomenon, which I call ‘discriminatory pricing.’ In Chapter 5 I discuss ‘algorithmic collusion,’ which occurs when pricing algorithms from rival firms converge on supracompetitive pricing, whether by intent or by accident. In Chapter 6 I present a theory of price regulation in general, applicable not only to algorithmic pricing but also to analog pricing. In the second part of the thesis, Chapters 7-10, I turn to more empirical questions in order to better understand the phenomenon and prescribe remedies. I examine what is and is not novel about these harms, and how they can be addressed. I analyse legal instruments like consumer law, competition law, data protection, contract law and new AI regulations in the United States, European Union, and United Kingdom to highlight gaps that leave consumers exposed to the harms discussed in previous chapters. I then propose policies to introduce or improve legal protections. Finally, I propose principles that firms interested in preventing or mitigating these harms might incorporate into the design, testing, and deployment of pricing algorithms.
