Abstrak: In Indonesia, the fishery commodities that can be developed are fish and shrimp. Fish and shrimp commodities is not only marketed in Indonesia but has been marketed overseas. So, the whole of the production process must be considered, one of them is harvesting that produced high-quality products. So far the harvesting process of fishery commoditiesin in Indonesia is still using the traditional method. The object of this research is to modify fish and shrimp harvester to produce an efficiency and effectiveness of harvesting machinery so that can be maintained the quality of fish and shrimp. Stages of this research are started from problems identification, analysis of the design, modification, and functional testing. Fish and shrimp harvester consist of vacuum pump and water pump. The functional aim of water pump is to suck commodities from the pond, where as and the vacuum pump is to maintain the vaccum condition inside the system. The results of this research obtained flow rate and suction velocity average are 1.84 l/s and 0.23 m/s in the tank 1. While in the tank 2, flow rate and suction velocity average are 1.63 l/s and 0.52 m/s respectively. At the end of this research, this modified fish and shrimp harvester is still not able to show good performance, and still need to conduct further research.

Abstrak: Products resulting from the fisheries sector is a good source of animal protein to meet the Indonesian people’s needs of nutritional and health. Some products that have a high protein value are shrimp and fish. The need for ease of getting farmed shrimp and fish in a pond increased, also include the harvesting results. Problems faced in fisheries harvesting is too much needed for resources and still lack of harvesting knowledge and skills. One way to minimize these problems is the use of mechanical harvester in harvesting pond. Another problems is that yields are still experiencing disability and high mortality rate. Design approach that taken are functional and structural design approach. From the results of the design will be carried out modeling and functional testing. Functional design is the design that has aspects related to the function and usefulness of each constituent element model of the commodities to be processed. Making models were created to test the success of harvesting systems that work in semi-continuous by vacuum suction mechanism. Because the model harvester shrimp / fish designed aiming to produce a work harvesting semi-continuous by vacuum suction mechanism. Measurements made in the form of rate water, time and speed of shrimp / fish down from the suction tank to the harvesting tank, the ratio number of the shrimp / fish in harvesting tank with shrimp / fish that are still left in the suction tank and pass rates of shrimp / fish alive. From the results obtained it can be seen the amount of shrimp that fell from suction tank to harvesting tank will vary for each time harvesting. The number of commodities that fall will be less and it could be more, depending on the time of harvesting. And the length of harvesting will make this harvester run semi-continuous.

Judul: Post-Truth dan Infodemi, Analisis Pengaruh Sosial dan Bias Kognitif Tokoh Agama dalam Literasi Informasi Kesehatan selama Pandemi Covid-19.
Abstrak: Upaya pengendalian pandemi Covid-19 dihadapkan dengan massifnya penyebaran disinformasi Covid-19, yang menyebar lebih cepat daripada virus itu sendiri. Penelitian ini bertujuan untuk menganalisa pengaruh sosial dan bias kognitif para tokoh agama terhadap resepsi disinformasi Covid-19. Penelitian ini menggunakan teori Encoding-Decoding Stuart Hall, di mana audiens akan memiliki resepsi untuk menerima, bernegosiasi atau menolak makna dari berita-berita mengenai konspirasi Covid-19 dan obat Covid-19. Penelitian ini juga menguji pengaruh bias kognitif dalam merespon informasi yang mendukung atau menolak resepsi mereka. Metode penelitian ini menggunakan metode kualitatif dengan informan enam orang tokoh agama yang berafiliasi dengan organisasi masyarakat (ormas) Islam di Kabupaten Bogor. Yaitu Majelis Ulama Indonesia, Nahdlatul Ulama dan Muhammadiyah. Pengumpulan data dilakukan dengan wawancara mendalam, dan studi dokumentasi. Penelitian ini menunjukkan bahwa dalam kasus berita mengenai konspirasi Covid-19, pengaruh sosial terhadap para tokoh agama berupa reference group, membership group, significant other dan source credibility tidak menjadi dasar pertimbangan resepsi para tokoh agama untuk setuju atau tidak setuju pada makna dari berita-berita tentang konspirasi Covid-19, tetapi lebih kepada keberpihakan politik dari sumber pengaruh sosialnya tersebut. Sementara dalam kasus berita mengenai adanya obat Covid-19, pengaruh sosial para tokoh agama lebih kepada percaya atau tidak percaya kepada orang-orang yang memberikan testimoni akan khasiat dari obat-obat yang dapat menyembuhkan Covid-19. Resepsi para tokoh agama terbagi menjadi dua, yaitu negotiated reading dan oppositional reading, dan tidak ada satupun yang memercayai disinformasi konspirasi Covid-19 dan obat Covid-19 sepenuhnya (dominant-hegemonic reading). Dalam kedua resepsi itu selalu hadir bias kognitif dalam bentuk cognitive dissonance bias, backfire effect bias dan confirmation bias. Mengingat peran penting tokoh agama di tengah masyarakat, perlu upaya lebih lanjut dari organisasiorganisasi Islam untuk memberikan edukasi mengenai literasi informasi kesehatan yang lebih komprehensif kepada para pengurusnya, agar antara kebijakan pemerintah dan sikap para tokoh agama dapat berjalan beriringan dalam menghadapi bahaya pandemi Covid-19.
