Graft copolymerization of acrylonitrile onto torch ginger cellulose

Graft copolymerization of acrylonitrile onto torch ginger cellulose was carried out in an aqueous medium with ceric ion redox initiator. The optimum grafting parameters such as temperature, reaction time, ratio of monomer to cellulose addition and ceric ammonium nitrate (CAN) concentration were determined and a maximum graft yield of 40% was recorded. The graft copolymer was characterized and compared with untreated cellulose. A new absorption peak corresponding to the nitrile group of acrylonitrile was recorded by FTIR at 2244 cm-1 on the grafted cellulose. The morphology studies showed that the diameter and the surface roughness of grafted cellulose had increased as compared with the untreated cellulose. On the contrary, the grafting had resulted in lowering the crystallinity of the cellulose from 63 to 53%. The grafted cellulose produced a new derivative TG peak at 420°C and higher residual percentage than the untreated cellulose

RESEPSI MAHASISWA TERHADAP PEMBERITAAN ANIES BASWEDAN SEBAGAI CALON PRESIDEN

The information media influences public attitudes in many aspects of life, including those concerning public political attitudes. Therefore the position of the media is very strategic in mapping public political attitudes. The media carrying the message constructs the message it makes. This study aims to analyze student reviews of the media coverage of Anies Baswedan as a presidential candidate in 2004. This study was designed with a qualitative approach, reception analysis method. Data collection techniques were obtained through surveys, literature review and documentation. The results of the study show that students have various attitudes after they learn about media coverage. Students who have a dominant-hegomonic position have reasons that Anies Baswedan is the best figure currently available; students who are in a negotiated position choose the moderate path to be more careful with the reason that they will first study the political figures that will appear ahead of the upcoming 2024 Indonesian presidential election; students who took an oppositional position without hesitation immediately rejected him on the grounds that Anies Baswedan was not fit to be president of Indonesia.   Keywords: Reality construction, social construction, student response, Anies BaswedanMedia informasi mempengaruhi sikap publik dalam banyak aspek kehidupan, termasuk di dalamnya menyangkut sikap politik publik. Karenanya posisi media sangat strategis dalam memetakan sikap politik publik. Media membawa pesan melakukan kontruksi atas pesan yang dibuatnya. Penelitian ini bertujuan untuk menganalisa resensi mahasiswa terhadap pemberitaan Anies Baswedan sebagai calon presiden 2004 oleh media. Penelitian ini dirancang dengan pendekatan kualitatif, metode analisis resepsi. Teknik pengumpulan data diperoleh melalui survey, kajian literatur dan dokementasi. Hasil penelitian menujukan bahwa mahasiswa memiliki sikap yang beragam setelah mereka mengetahui pemberitaan media. Mahasiswa yang memilik betsikap dominat-hegomonic position memiliki alasan bahwa Anies Baswedan merupakan figur terbaik yang ada saat ini;  mahasiwa yang bersikap negotiated position memilih jalan moderat lebih hati-hati dengan alasan akan memelajari terlebih dulu figur-figur politisi yang akan muncul menjelang pemilihan presiden Indonesia pada 2024 mendatang; mahasiswa yang bersikap oppositional position tanpa ragu langsung menolaknya dengan alasan Anies Baswedan belum layak menjadi presiden Indoensia.

Chasing the same fish: Collaborative management initiative for shared fish stocks among the ASEAN countries

Overexploitation and severe depletion of marine fisheries resources in Southeast Asia continue to be a source of great concern to many regional fisheries managers.The fact that ASEAN countries bordering these waters are highly depended upon marine fisheries as the main source of revenue, employment, and food security, it is crucial for them to address these fisheries problems.This is especially the case with respect to the management and conservation of commercially important shared pelagic fish stacks, particularly in the South China Sea and Celebes Sea As the spatial migratory range of these stock transcends across many politically draw maritime zones of littoral States, it is highly impossible for one State, acting independently, would be able to manage these fisheries effectively within its own national jurisdiction Perhaps the best approach in dealing with this problem is through collective management and conservation of fish stocks.Hence, this paper examines interstate cooperative arrangement for the management of shared fishery stocks among ASEAN countries.It begins by providing brief definition, biological and migratory profile of transboundary shared stocks. The second part covers existing international legal and policy framework that embraces the principle of interstate cooperation for managing such stocks.Finally, the paper provides recommendations of how ASEAN member States can address the issues and challenges of managing shared fish stocks in a more holistic and coordinated manner within the framework of interstate cooperation

Examining the Role of Social Network on Opportunity Recognition: A Propose Framework

The fundamental activity of entrepreneurship is new venture creation.Therefore, one of the major components of any entrepreneurial venture is the recognition of the opportunity by the entrepreneur.Identifying and selecting the right opportunities for new venture are among the most significant abilities of successful entrepreneur. Hence, explaining the discovery and development of opportunities per se is a key part of entrepreneurship research.This paper builds on the existing theoretical background of opportunity recognition and aimed at investigating the role of entrepreneur’s prior social network towards bridging to information sources that would help entrepreneurs recognizing opportunity

Border security problems in the waters of the Natuna Islands: between national boundaries and illegal fishing

Natuna or better known as the Natuna Islands is one of the border areas in Indonesia that has complex problems. As a cluster of islands bordering Indonesia with Malaysia and Vietnam, the Natuna Islands are also located in the South China Sea region, which is a regional dispute hot spot in East Asia. This paper will discuss the concept of border security and border security issues in the waters of the Natuna Islands. In this paper, the authors argue that the problem of the Indonesian EEZ maritime boundary in the Natuna Islands territorial waters with Malaysia and Vietnam needs to be immediately resolved, because in addition to sovereignty, the precision of the EEZ boundary with neighboring countries will be related to the management of natural resources contained in the particular territorial waters. This condition is increasingly complicated when China with its nine-dashed line has raised problems of overlapping claims in the Natuna waters. In addition, the obscurity of maritime boundaries is used by certain parties to carry out illegal fishing in the maritime areas currently being disputed by the neighboring countries

Maritime border security and challenges for Indonesia

The issue of border security had drawn much attention for being an important part of a country’s national security and sovereignty, in addition to its dynamic and complex nature. Indonesia as an archipelagic country faces many problems and challenges in its maritime border areas, in addition to the problems of unresolved state borders with its neighboring countries. Indonesia also faces various trans-boundary crime actions near the maritime border areas. This study aimed at developing a conceptual framework of maritime border security and explaining the challenges of maritime border security. This study applied the qualitative approach by focusing on secondary data. The secondary data were obtained by means of analyses of documents, books, journals, magazines, bulletins and newspaper, including internet sources that were relevant with this study. The findings of this study show that Indonesia faced dynamic and complex problems of maritime border security, not only the problems of unsettled borders with several neighboring countries, but also many transboundary criminal activities in its maritime border areas. The problems of overlapping regulations and institutions added up to the problems to cope with the problems of maritime border security. This study recommends that the government of Indonesia needs to intensify the border diplomacy regarding the maritime borders with the neighboring countries in order to reach delimitation agreements of its maritime border. Further, the government of Indonesia should do immediate reorganization of regulations and institutions of maritime border security to handle all forms of trans-boundary crimes

Effect of Bacillus Subtilis Bacteria on The Mechanical Properties of Corroded Self-Healing Concrete

Reinforced concrete has a weakness for corrosion which can cause the concrete to crack and the concrete structure to fail. To overcome this problem, a self-healing concrete method is needed that can close cracks and inhibit the rate of natural corrosion. Bacillus subtilis as a self-healing agent in concrete has been proven to be able to increase the compressive strength and flexural strength of concrete. The method used in this research is to add bacterial hydrogel encapsulation to concrete with a variation of 0%; 0.1%; 0.6%; and 1.5% by weight of sand. The test object is a reinforced concrete beams and cylindrical concrete with compressive design strength of 30 MPa. The concrete specimens will go through a series of tests, such as corrosion acceleration tests using DC power supply, self-healing tests by visual observation, flexural strength, ductility, stiffness, and compressive strength tests using Universal Testing Machine (UTM). From the test results, it was found that the addition of 0.1% bacterial encapsulation variation was the optimum value for increasing the mechanical properties of self-healing concrete and reduce the corrosion rate on self-healing concrete
