Kajian tekno-ekonomi kemungkinan pendirian industri pengolahan khitin di Kabupaten Kota Makassar, Propinsi sulawesi Selatan telah dilakukan dengan tujuan untuk mengevaluasi kelayakan pasokan bahan baku, disain proses dan teknologinya, kelayakan finansial dan dampak terhadap ekonominya. Analisis kelayakan pendirian industri khitin ini didasarkan pada dua kapasitas yaitu pertama dengan kapasitas 3 ton kulit udang per hari dan kedua dengan kapasitas 4 ton kulit udang. Hasil analisis kelayakan menunjukkan bahwa industri pengolahan khitin dengan kapasitas 4 ton kulit udang per hari secara finansial layak didirikan di Makassar. Namun industri pengolahan khitin yang erkapasitas 3 ton kulit udang per hari pun secara finansial layak didirikan meskipun nilainya tidak setinggi industri khitin yang berkapasitas 4 ton kulit udang per hari. Analisis sensitivitas dilakukan pula untuk mengetahui kelayakan industri pengolahan khitin terhadap pengaruh perubahan harga bahan baku, harga bahan kimia pembantu yang dipakai, biaya produksi dan harga khitin. Hasil analisis sensitivitas menunjukkan bahwa industri pengolahan khitin sangat dipengaruhi atau sensitif terhadap perubahan harga bahan baku, harga bahan kimia pembantu yang dipakai, biaya produksi dan harga jual khitin.

The purposes of this research were to observe prevalence, distribution and reproduction failure evidence of dairy cattle brucellosis in DKI Jakarta . To determine the group of cattle infected with Bntcella abortus, senim and milk samples were carried out . At the beginning, bulk of milk samples were collected from containers . Futhermore, the blood samples were simple randomly collected on cattle that were suspected positive brucellosis in the milk ring test . Those serum samples were tested by using rose bengal plate and complement fixation test . Questioner data in relation with on any reproductive failures, such as abortion, premature dead and born weak, were gathered from farmer within 8 consecutive month period . The result indicate that screening of brucellosis using milk ring test based on bulk milk sample was effective tools to determine the infected group of cattle . The average prevalence of brucellosis in DKI Jakarta area was 4 .5 %. Distribution of brucellosis prevalence were 8 .5% at Setiabudi, 2 .3% at Mampang Prapatan, and 2 .9% at Pasar Minggu . Brucellosis was found at least 201 cattle from 38 dairy cattle farm in DKI Jakarta . Brucellosis was caused abortion about 62 .5% dairy cattle and this value was significantly different than that of uninfected cattle (P<0.05) . Brucellosis also cause stillbirth around 9 .8% and born weakness 15 .2% . The widely distributed and high prevalence brucellosis of dairy cattle in DKI Jakarta was influenced by uncontrol of cattle movement and high abortion cases rate .

Live vaccine of Brucella abortus strain 19 has been used for prevention and eradication of brucellosis in cattle . The information of the use of this vaccine in Indonesia is still limited, while the effectivity, bacteriological and serological aspects of the vaccine are not much evaluated yet. The objective of this research is to study the differences of protein cell wall antigenicity profiles between B. abortus strain 19, strain 544 and field isolates. Protein cell wall was prepared by sonicafion of B. abortus S19, S544 and B. abortus field isolates biotype l, 2 and 3 . Antiserum against these B. abortus was prepared in cattle . Futhermore, the distribution of protein band was determined by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE), while protein antigenic profiles was examined by immunoblotting . The result showed that there was no significant different amongs protein cell wall of these B. abortus. From the antigenicity profiles exhibited that cattle vaccinated with B. abortus S19, no antibody was detected against protein less than 30 kDa. The other side natural infected or experimental infected cattle with B. abortus biotype 1 field isolate, antibody was detected until protein which has molecular weight about 15 kDa.

The aim of this work was to study the pathogenicity of Brucella suis field isolate and its ability to transmit the disease from pig to human. The transmission ability of field isolate of B. suis was studied by using 4 brucellosis negative pigs which were put together with one of the artificially infected pig. The transmission ability of the diseases from pig to human was carried out by collecting blood samples from pigs and from the workers of pig farms and abattoir and tested them with the Rose Bengal Plate Test. The result indicated that field isolate of B. suis biotype 1 was pathogenic for pigs with the ID50 of 500 CFU. The infection was widely distributed into several organs or lymphnodes such as retropharingeal, submaxillaris, femoralis, suprascapularis, supramamaria and the spleen. The transmission of brucellosis from artificially infected pigs to negative pig in the group occurred between 4-6 weeks after they were put together. Brucellosis in the pigs was transmittable and causing brucellosis to workers of pig farms and abattoir. Key words : Brucella suis, pathogenicity, transmission, pig, human

Crude palm oil (CPO)is the richest natural plant source of carotenoids in terms of retinol (pro-vitamin A) equivalent, whereas palm oil mill effluent (POME) is generated from palm oil industry that contains oil and carotenes that used to be treated before discharge. Carotenoids are importance in animals and humans for the purpose of the enhancement of immune response, conversion of vitamin A and scavenging of oxygen radicals. This component has different nutritional functions and benefits to humaan health. The growing interest in the other natural sources of beta-carotene and growing awareness to prevent pollution has stimulated the industrial use of CPO and POME as a raw material for carotenoids extraction. Various technologies of extraction and separation have been developed in order to recover of carotenoids.This article reports on various technologies that have been developed in order to recover of carotenoids from being destroyed in commercial refining of palm oil and effects of some various treatments on the extraction end separation for carotenoid from palm oil and carotenoids concentration. Principally, there are different technologies, and there is one some future which is the use of solvent. Solvent plays important role in the most technologiest, however the problem of solvents which are used is that they posses potentiaal fire health and environmental hazards. Hence selection of the most safe, environmentally friendly and cost effective solvent is important to design of alternative extraction methods.Chemical molecular product design is one of the methods that are becoming more popular nowadays for finding solvent with the desired properties prior to experimental testing.ABSTRAKMinyak sawit kasar merupakan sumber karotenoid terkaya yang berasal dari tanaman sawit sebagai senyawa yang sama dengan retinol atau pro-vitamin A; sedangkan limbah pengolahan minyak sawit dihasilkan dari industri pengolahan minyak sawit yang berisi minyak dan karotene yang perlu diberi perlakuan terlebih dahulu sebelum dibuang. Karotenoid merupakan bahan penting yang diperlukan pada hewan dan manusia guna memperkuat tanggapan terhadap kekebalan, konversi ke vitamin A dan penangkapan gugus oksigen radikal. Dengan berkembangnya ketertarikan dalam mencari beta-karotene yang bersumber dari alam lain dan meningkatnya kesadaran untuk mencegah adanya pencemaran lingkungan, maka mendorong suatu industri untuk menggunakan CPO dan POME sebagai bahan baku untuk diekstrak karotenoidnya. Berbagai macam teknologi guna mengekstrak dan memisahkan karotenoid telah dikembangkan untuk mendapatkan kembali karotenoidnya. Makalah ini melaporkan dan membahas berbagai jenis teknologi yang telah dikembangkan guna mendapatkan kembali senyawa karotenoid dari kerusakan di dalam proses pemurnian minyak sawit secara komersial dan pengaruh beberapa perlakuan terhadap ekstrasi dan pemisahan karotenoid dari minyak sawit dan konsentrasi karotenoidnya. Pada prinsipnya, berbagai teknologi yang digunakan untuk mengekstrak dan memisahkan karotenoid terdapat perbedaan, dan terdapat salah satu teknologi yang digunakan untuk esktrasi dan pemisahan karotenoid adalah menggunakan bahan pelarut. Pelarut yang digunakan mempunyai peranan yang penting dalam teknologi ekstrasi; namun pelarut yang digunakan untuk mengekstrak tersebut mempunyai persoalan karena berpotensi mengganggu kesehatan dan membahayakan cemaran lingkungan. Oleh karena itu, pemilihan jenis teknologi yang aman, ramah terhadap lingkungan dan biaya yang efektif untuk penggunaan pelarut merupakan hal penting sebelum dilakukan desain metode/teknologi alternatif untuk esktrasi karotenoid. Pola produk molekuler kimia merupakan salah satu metode yang saat ini menjadi lebih populer untuk mencari pelarut dengan sifat-sifat yang dikehendaki sebelum diujicobakan. Kata kunci : karotenoid, ekstrasi, pemisahan, teknologi, minyak sawit kasar, limbah industri pengolahan sawit.

There is a certain dualism of the social media in the context of institutionalizing the values of democracy and public sphere. On the one hand, the social media seems to be able to overcome the paradox of mass communication by making each individual the subject of its own by him or herself. In the social media there is no hierarchical dischotomy between the elite and the common people which is usually the case in mass communication. In the social media , each individual is the producer –and in the same time –the publisher and information discourse. Yet, on the other hand , this deliberativedemocratic social media carries its negative side causing a rather serious impact is becoming a communication sphere with an anti-communication character; a communication based on prejudice, a priori and indifference towards the feelings of others. How can it be called communication when its reality it has become the means to curse, hate and propogate sarcasm towards others? The social media is presenting some very serious ethical problems in to our public sphere and the promotion of democracy. The social media is in hand is worth it by the sphere of promotion.

Semakin aktif kita menggunakan layanan-layanan digital, semakin banyak data diri kita yang ditambang perusahaan yang mengoperasikan layanan digital itu. Oleh karena itu, layanan digital seperti surel, media sosial, mesin-pencari tidak pernah sepenuhnya gratis. Layanan gratis itu mesti ditukar dengan data-perilaku-pengguna-internet (internet-user-behavior-data) yang gratis pula. Dalam perjalanannya hal ini menciptakan penguasaan dan pengendalian atas data-pribadi semua pengguna internet oleh perusahaan platform digital global. Data-pribadi yang memiliki nilai ekonomi-politik yang besar sekali. Paper ini mempersoalkan monopoli data-perilaku-penggunainternet itu, dengan menampilkan konsep data-perilaku-pengguna internet sebagai hak milik pengguna internet (data as labor).
