Profil Asam Lemak Bakasang yang Dibuat dengan Variasi
Get PDFBakasang merupakan produk pangan yang diolah melalui proses fermentasi jeroan ikan dan merupakan salah satu makanan khas wilayah Indonesia bagian timur terutama Sulawesi Utara. Pengolahan Bakasang di Sulawesi Utara umumnya masih sangat sederhana, isi perut ikan biasanya dimasukkan bersama garam ke dalam botol plastik, kemudian dijemur dibawah terik matahari beberapa hari hingga berubah menjadi cairan. Penelitian ini dimaksudkan untuk mengetahui profil asam lemak Bakasang yang diolah dengan suhu terkontrol dengan variasi waktu fermentasi 5, 10 dan 15 hari, menggunakan kadar garam 10 dan 20%. Uji profil asam lemak dilakukan menggunakan Kromatografy Gas-Spektrofotometer Massa (GC-MS) dengan terlebih dahulu dilakukan proses ekstraksi dan transesterifikasi. Hasil penelitian menunjukkan bahwa waktu fermentasi berpengaruh terhadap profil asam lemak Bakasang. Meningkatnya waktu fermentasi Bakasang akan meningkatkan jumlah puncak dalam kromatogram. Kadar (poly unsaturated fatty acid) PUFA Bakasang menurun dengan meningkatnya waktu fermentasi, sebaliknya kadar asam lemak jenuh meningkat dengan meningkatnya waktu fermentasi. Senyawa asam lemak dominan dalam Bakasang adalah asam heksadekanoat, asam lemak oktadekanoat dan eicosa pentaenoic acid (EPA). Kadar EPA Bakasang tertinggi adalah 30.12% yakni Bakasang yang diolah dengan lama fermentasi 5 hari, menggunakan kadar garam 10 dan 20%

User Awareness Design for Electronic Money User Using Protection Motivation Theory and NIST 800-50 Framework
Get PDFElectronic money has emerged as the payment method. It becomes more popular because it is convenient and ubiquitous. However, the popularity has caused new security threats for the the user of electronic money. Personal data and financial information are the main target of the threats. Individuals need to protect and have certain responsibilities regarding their personal data and financial information used for electronic money services. Technology alone is unable to prevent the threats. Human behavior also becomes crucial factor to protect people against the threats and plays essential role in safe guarding personal data and financial information. This study uses Protection Motivation Theory (PMT) as a theoretical framework to empirically test why people do precautionary behavior on electronic money transaction. PMT is a social-cognitive model to predict and explain prevention behavior. Empirical research is conducted using survey methodology and collecting data from 186 respondents using online forms. Partial Least Square structural equation modelling provides support for factors influencing protection motivation in electronic money context. The results provide support for the use of threat and coping appraisal, in particular perceived security vulnerabilities, perceived security threat and perceived response efficacy to influence precautionary behavior in the context of electronic money. Those results contributes to the design of user awareness programs using NIST Special Publication 800-50. The awareness programs aimed at precaution behavior, thereby empowering electronic money user to protect themselve

Analysis of Steel Plate Shear Wall Performance with Two Wall Openings Modification
Get PDFSteel plate shear wall (SPSW) is one kind of steel earthquake resistant building structural stiffener that can dissipate the tremendous amount of quake energy, where the steel plate itself had been developed from years, and still in development. Ideally, SPSW is designed so all of its parts can absorb the energy of lateral force, seismic load for instance, through inelastic deformation. Because of that, the thickness of applied steel plate in a section of a building (a portal in this case) is determined by the shear force of the portal itself. In this research, experiment had been done using multiple applicable methods for the SPSW, where the use of it depends on the architect aspect and necessity. In this experiment, the specimen will be tested with some applicable lateral loading, where in the steel plate itself, there are two openings applied to the web plate. The result of the research shows some behavior changing of the dissipating energy throughout the steel plate, especially along the edge of the openings. Because of that fact, there are some performance degradation in the specimen, compared to the normal steel plate with stiffeners, which is 26.61% reduction of ultimate strength (624.01) kN at perforated specimen, compared to 850.24 kN at non-perforated specimen) and 11.5% reduction of dissipated energ
A concept to Reduce Idle Time on Stevedoring Activities in a Container Terminal
Get PDFThe flow of goods is still dominated by sea transport compared with other modes of transport so that the container terminal is very important role in the economic system of a country. The main indicator of performance of a container terminal is the total container throughput in TEUs per year. Recording is done in the process of stevedoring activities. It was found that the idle container cranes (CC) increases higher than the increase in throughput that is 77% compared with 22%. This should not apply instead. Waiting for a load and Combined Terminal Tractor (CTT) / truck are the largest contributor to the idle CC. No one can be sure that the cargo does not exist because there is no CTT which brings, or the container is not ready. The results showed that by changing the arrangement of CC and CTT obtained the increase in number of containers underserved. Another result is a decrease in the average number of ships that was rejected due to full berth and unloading equipment utilizatio
