Occupational Health and Safety Risk Analysis Using AS/NZS Standard 4360:2004 in a Fish Meatball Industry
No full textThe Indonesian fishing industry developed by 1.4% in 2020, compared to the previous year, as shown by the existence of around 773 seafood factories. Such growth caused the emergence of different working conditions due to the use of complex machines. In 2019, the industrialization process generated an immense potential for accidents on occupational health as the mishaps increased from 60 to 270 cases. For this reason, this study aimed to identify the value and level of risk, using HIRARC (Hazard Identification Risk Assessment and Risk Control) following AS/NZS 4360:2004 standards. The study was conducted at the fish meatball company located in East Java, for six months. The results showed that the company could manage the occupational health and safety, as indicated by the reduction of the levels of risk from acceptable (33.4%), priority 3 (14.3%), priority 2 risk (38.1%), priority 1 risk (9.5%), and very high risk (4.8%) to acceptable (76%) and priority 3 (24%). The risk assessment matrix had shifted from yellow (moderate) to green (low). Some recommendations implemented in the workplace included creating a safety organization, organizing training sessions among employees, fostering a safety culture, applying ergonomic principles, and controlling work hours

POTENTIAL OF Spirulina sp. FOR REMEDIATING POLLUTANTS IN AQUACULTURE WASTEWATER AND PRODUCING PHYCOCYANIN
Get PDFThe sustainability of aquaculture wastewater treatment is challenging because it has a negative impact on the ecosystem if directly discharges to the environment. Aquaculture wastewater consists of high pollutants loading such as ammonia, phosphor, nitrate, and chemical oxygen demand. To offset the downsides of aquaculture effluent, effective solutions are required. Spirulina sp. is as microalgae that convert nutrients in the wastewater and dissolve carbon into microbial biomass with value such as phycocyanin which can be employed as food, cosmetics, feed, and pharmacy feedstock. The effects of light intensity (6,000 - 10,000 lux) and urea addition (20-100 ppm) on biomass production, COD reduction, and phycocyanin yield were investigated in this study. For 10 days, Spirulina sp. was grown in a batch reactor at 25-27°C with a ratio of 30% inoculum and 70% wastewater under continuous aeration. Spirulina sp. produced the most biomass at 8,000 lux with the addition of 60 ppm of urea accounting for 0.71±0.14 g/L (P > 0.05). Meanwhile, the maximum phycocyanin concentration was 4.21±0.132% at 7,000 lux and 80 ppm urea (P > 0.05) with 96.51% of chemical oxygen demand reduction (P < 0.05). The outcomes of this study highlight the potential of aquaculture effluent to produce valuable microalgal biomass and phycocyanin, which can be used to generate lucrative products
Analisis Finansial Penggunaan Panel Surya Pada Budi Daya Udang Vaname
Get PDFPada sistem budi daya udang intensif, penggunaan kincir air menjadi salah satu kunci keberhasilan budi daya. Kincir air memegang peranan penting dalam penyediaan oksigen terlarut untuk kehidupan udang. Saat ini, kincir air yang banyak digunakan adalah yang menggunakan listrik sebagai tenaga penggeraknya dan menghabiskan sekitar 14-15% dari biaya total yang dibutuhkan selama masa pemeliharaan. Hal inilah yang membuat para pembudidaya membutuhkan biaya operasional yang tinggi untuk menggunakan kincir air. Oleh sebab itu, menjadi penting untuk menganalisis kebutuhan biaya listrik untuk budi daya udang vaname dengan sistem intensif; menganalisis persentase penurunan biaya dengan penerapan solar panel sebagai penggerak kincir pada budi daya udang vaname; dan menganalisis parameter finansial pada budi daya udang vaname yang menggunakan solar panel sebagai pengganti listrik. Penelitian ini telah dilakukan selama dua siklus budi daya pada tambak udang vaname di Kabupaten Jembrana, Bali menggunakan metode survei dan pengamatan di lapangan. Hasil penelitian menunjukkan bahwa kebutuhan penggunaan listrik untuk menggerakkan kincir air menelan biaya hingga 9,04% dari biaya total produksi selama masa pemeliharaan. Tingginya kebutuhan listrik yang mencapai 95.040 kWh per tahun untuk empat kolam tambak dengan luas 5.600 m2 menyebabkan penggunaan solar panel menjadi sebuah solusi yang tepat. Selain disebabkan karena penggunaan energi terbarukan yang ramah lingkungan, penggunaan solar panel untuk mensubstitusi listrik konvensional juga mampu menurunkan biaya operasional hingga 1,47% dan meningkatkan keuntungan usaha hingga 44,60%. Dengan demikian, penggunaan tenaga surya terbukti dapat menjadi solusi budi daya berkelanjutan. Akan tetapi, penerapan energi ini masih belum maksimal sehingga diperlukan dukungan pemerintah dalam bentuk kebijakan dan peraturan serta pengembangan kerja sama internasional Tittle: Financial Analysis of the Utilization of Solar Panels in the Vannamei Shrimps Farming In intensive shrimp farming system, the use of waterwheels is one of the keys to successful cultivation. Waterwheels play an important role in providing dissolved oxygen which is essential for shrimp life. However, the majority of waterwheels use electricity as its driving force and spends around 14-15% of the total cost required during the maintenance period. Because of this, cultivators need to incur significant operating costs in order to employ waterwheels. Therefore, it is important to analyze the need for electricity costs for vannamei shrimp farming with an intensive system, analyze the percentage of cost reduction by applying solar panels as a wheel drive, and analyze the financial parameters in using solar panels as an electric replacement. This study was conducted for two cultivation cycles in vannamei shrimp ponds in Jembrana, Bali utilizing survey and direct observation in the location. The results showed that the need to use electricity to drive the waterwheels costed up to 9.04% of the total production cost. The high demand for electricity, which reached up to 95,040 kWh per year for four ponds with an area of 5,600 m2, showed that the use of solar panels is a viable eco-friendly renewable energy solution. The use of solar panels decreased operational costs by up to 1.47% and raised business earnings by up to 44.60%. Thus, it has been shown that using solar energy for farming is a sustainable approach. Though this energy is still not being used to its full potential, government support in the form of laws and regulations as well as the growth of international cooperation are required

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
