Inflationary Pressures Surrounding COVID – Are Price Increases Consistent With Changes in Costs
Authors: Chi Yu-Ho , Ziebart David A.
Published: April 2024

Evidence suggests that companies are more eager to raise prices than to cut them (Karaian et al., 2023). Profit margins remain high even as inflation drops. This is accomplished by raising or holding prices steady as inflation shrinks. We examine the changes in selling prices and underlying costs between pre and post COVID periods. We expect that the shift in the relation between selling price and underlying costs prior to COVID would be less than the shift post-COVID. We investigate grocery food items because food inflation has been a main driver of inflation in the United States and other countries (Cavallo, 2022). Focusing on this specific cost behavior between the pre- and post-COVID periods allows us to measure the relationship between raising selling prices and related underlying increases in cost of goods sold and selling, as well as general and administrative expenses. The inference from our analyses suggests that food companies may have taken advantage of COVID-driven inflation to justify and increase their profit margins.

Authors: Zhang Shuping , Su Xiaofeng , Sheng Shirley Ye
Published: April 2024

Consumers’ attitudes toward corporate social responsibility (CSR) and their response levels can significantly affect a firm’s behaviors. Based on 61 research papers addressing CSR responses to consumers in China, this study conducted a meta-analysis on three variables: CSR type, CSR characteristics, and CSR publicity behavior, which impact the CSR relationship. The following conclusions are drawn: Corporate social responsibility (encompassing private and public moral dimensions) elicits a positive consumer response, with private moral behavior having a greater positive effect compared to public moral behavior. The four dimensions of CSR characteristics (CSR commitment, CSR level, CSR correlation, and CSR timing) all lead to positive consumer responses. Positive consumer responses also arise from CSR publicity behavior, including publicity initiative and publicity intensity. Additionally, product type, sample time, and sample source have significant moderating effects on these relationships.

Authors: Karsam Karsam
Published: April 2024

AbstrakFotografi hanyalah sebuah tindakan mekanis dalam menghasilkan suatu gambar, bukan representasi tetapi hanyalah peristiwa kausal, bukan gambaran imajinasi, namun hanya kopian. Fotografi mengandaikan adanya kemudahan dalam penciptaan seni. Perkem­bangan teknologi akhirnya melupakan sisi estetis dan hanya berpasrah sepenuhnya pada tindakan mesin. Penekanan berlebihan terhadap keunggulan reduplikasi, proses instan, dan otomatisasi fotografi membuat fotografi kehilangan tempatnya di dunia seni.

Tujuan yang ingin dicapai adalah menghasilkan karya reproduksi fotografi teknik ukir “rayap” menggunakan media kayu jati sebagai upaya pengembangan penciptaan bidang seni rupa. Fokus penelitian ada pada mengolah foto dan teknik ukir “rayap” dengan menggunakan media kayu jati. Metode yang digunakan adalah metode kualitatif dengan pendekatan triangulasi. Penelitian ini menghasilkan karya seni rupa dua dimensi berupa foto yang dibuat dengan menggabungkan dua teknik, yaitu teknik reproduksi fotografi dan teknik ukir kayu.  Kelebihan dari penelitian ini adalah belum ada peneliti yang melakukan sebelumnya. Dengan dibuatnya fotografi teknik ukir “rayap” ini dapat membantu perkembangan seni rupa modern di Indonesia. Selain itu karya yang dihasilkan dapat meningkatkan nilai ekonomi. Kata Kunci: fotografi, rayap, reproduksi, teknik ukir kayu AbstractPhotography is only a mechanical action in producing an image, not a representation but only a causal event, not an image of imagination, but only a copy. Photography presupposes the ease of creating art. The development of technology has finally forgotten the aesthetic side and just surrendered completely to the actions of machines. Excessive emphasis on the advantages of reduplication, instant processing, and photographic automation has made photography lose its place in the world of art. In 2015, portrait painting was developed in the form of Wedha's Pop art Portrait (WPAP). This is the background of this research. The goal to be achieved is to produce a work of photographic reproduction of the "termite" carving technique using teak wood media as an effort to develop creation in the field of fine arts. The research focus is on photo processing (photo editing) and “termite” carving techniques using teak wood media. The method used in this study is a qualitative method with a triangulation approach. This research produces two-dimensional works of art in the form of photographs made by combining two techniques, namely photographic reproduction techniques, wood carving techniques. The advantage of this research is that no researchers have done it before. It is hoped that the photography of the “termite” carving technique will help the development of modern art in Indonesia. In addition, the work produced can increase economic value. Keywords: photography, reproduction, termite, wood carving techniques

The Predicted Structure of a Thermophilic Malate Synthase
Authors: Nielsen Shaelee , Orton Jantzen , Howard Bruce
Published: March 2024

This project aims to solve the structure of the crenarchaeal Sulfolobus acidocaldarius enzyme malate synthase. Other known malate synthase enzymes have been found to require a magnesium ion in the active site to carry out catalytic activities, but a study reported that S. acidocaldarius malate synthase does not require magnesium. This suggests a novel mechanism for this enzyme. Additionally, the mature S. acidocaldarius protein is approximately 100 residues larger than any other structurally characterized malate synthase. It has also been reported to form a dimer, while previously solved structures have only displayed monomeric, trimeric, and hexameric arrangements. We plan to determine the structure experimentally. However, major advances in the accuracy of protein structure prediction were made recently by AlphaFold, an artificial intelligence system developed by DeepMind, which has revolutionized the field and has largely solved the protein folding problem. A similar AI system, RoseTTAFold, developed by David Baker’s lab at the University of Washington, has been publicly available. Here, we report our analysis of the structure of this protein, predicted using both of these algorithms and of a predicted structural model for the dimeric form of the enzyme using ClusPro. Our results strongly support a conserved catalytic mechanism requiring magnesium, which is common with all previously solved malate synthase isoforms.

Measurement System for Compliance in Tubular Structures
Authors: Kludze Ave , D’Amato Anthony , Wang Yadong
Published: March 2024

Tubular structures such as blood vessels, intestines, and the trachea are common in various life forms. This paper describes a measurement system to test the mechanical compliance of tubular structures. The novelty of the system lies in its hardware and software. Here we use vascular graft as an example to demonstrate the utility of the system. A fully synthetic vascular graft would ideally mimic the mechanical and architectural properties of a native blood vessel. Therefore, mechanical testing of the graft material under physiological pressure is crucial to characterizing its potential in vivo performance. The device operates through a low-cost Arduino-based control system that simulates and measures cyclic fluid pressure changes over time and a laser micrometer that measures diameter changes with pressure. This system is low-cost, assuming one already has access to a laser micrometer. In contrast to previous methods, this system offers a simple, low-cost, and customizable option to measure compliance and is equipped with data acquisition/analysis programs. These programs include a MATLAB application that processes and synchronizes Arduino Uno pressure signals and LabChart Pro diameter readings. Lastly, this paper explains the hardware and software of the measurement system. The system is beneficial for testing the pressure-diameter relationship of tubular structures of varying sizes and materials. KEYWORDS: Tubular Structures; Compliance; Data Acquisition System; Physiological Pressure; Diameter Change; Arduino Uno; LabChart Pro; MATLAB
Impacts of Brent Crude Oil Price Fluctuations on Global Aquaculture Production During World Economic Crises
Authors: Yiğit Ümüt
Published: March 2024

This study evaluates the linkage between brent crude oil prices and volatility spillover on the global aquaculture volume -and values during world economic crises. Besides the main variable costs comprising feed expenses with over the half of total costs in aquaculture facilities, the energy expenditures are among the important operational costs that influence farm profits through feed costs overall, but also with direct effects in recirculating systems as electricity use. Findings in this study evidenced that global aquaculture volume and value is closely related to global brent crude oil price variations during the periods of crises, as a result of increase in production costs. The correlations between brent crude oil prices and percent changes in volume -or values of farmed fish covering the crises periods between 2008 and 2021 were highest as 0.798 (R=0.798134676) and 0.716 (R=0.715832960), respectively, which are close to zero “0”, showing strong correlations between the investigated structures. However, no correlation was found between the investigated structures during the pre-crisis, post-crisis or inter-crisis periods. Over the last ten years, there were three periods when brent oil prices dropped remarkably, with interrelated effects on world aquaculture production volume or values with severe price dip following the brent oil trends. Hence, the results from this study reveal that any severe change in the energy sector will in turn hit the aquaculture industry with significant influences on both production volume -and values. Therefore, information regarding the interrelation of brent crude oil price variations and global aquaculture production provided in this study, may support building management strategies for sustainable fish farming business with foresights to world economic crises.

Biomassa dari limbah daun mahoni dan daun bambu saat ini belum dimanfaatkan secara maksimal, sehingga perlu adanya pengolahan lebih lanjut. Kedua limbah daun tersebut dapat diolah menjadi bahan bakar alternatif terbarukan berupa briket. Sehingga, penelitian ini bertujuan untuk mengetahui pengaruh komposisi campuran dari daun mahoni dan daun bambu terhadap kualitas briket. Tahapan penelitian ini adalah sortasi, pirolisis, pengayakan, pencampuran (komposisi arang daun mahoni (ADM) dan arang daun bambu (ADB) yaitu 10:90; 30:70; 50:50; 70:30; 90:10 (% w/w)), penambahan perekat (tapioka 10%), pencetakan, pengeringan, serta pengujian. Tahap pengujian briket yang dilakukan yaitu uji kerapatan, uji waktu pembakaran, uji kadar air, uji kadar abu, uji nilai kalor, dan uji warna pembakaran. Hasil terbaik pengujian nilai kalor tertinggi 5.346,17 kal/g; nilai kadar abu terrendah 33,33%; nilai kadar air tertinggi 37%; nilai kerapatan tertinggi 0,76 g/cm3; nilai waktu pembakaran tertinggi 0,87 g/menit terdapat pada variabel ADM:ADB 90:10 (% w/w). Sedangkan untuk nilai kalor terendah 4,15 kal/g terdapat pada variabel ADM:ADB 70:30 (% w/w) dan nilai waktu pembakaran terendah diperoleh 0,56 g/menit pada variabel ADM:ADB 10:90 (% w/w). Sehingga dapat disimpulkan bahwa hasil uji menunjukkan semakin besar komposisi masing-masing bahan baku maka nilai parameter kualitas briket akan mendekati syarat SNI 01-6235-2000. Namun, nilai kadar air dan kadar abu yang diperoleh pada semua variabel tidak memenuhi syarat SNI, maka dari itu di perlukan penelitian lebih lanjut yang berhubungan dengan pengeringan briket dan campuran komposisi briket agar parameter briket sesuai dengan syarat SNI.

Pusat perbelanjaan yang terletak di Kawasan Dinoyo Kota Malang memiliki IPAL dengan pengolahan secara kimia melalui koagulasi-flokulasi dan biologi melalui aerobik. Pengolahan koagulasi-flokulasi menggunakan koagulan tawas. Namun, tawas yang digunakan masih terlalu banyak dan masih belum dapat menurunkan parameter hingga sesuai baku mutu. Alternatif koagulan yang dapat digunakan yaitu Al2(SO4)3, yang dapat menurunkan nilai TSS, BOD, COD, dan kekeruhan dengan harga terjangkau. Tujuan penelitian ini adalah menganalisis pengaruh rasio koagulan Al2(SO4)3 1000 ppm terhadap parameter pH, TDS, TSS, kekeruhan, COD, BOD, dan minyak/lemak pada pengolahan limbah cair pusat perbelanjaan secara koagulasi-flokulasi. Metode koagulasi-flokulasi dilakukan pada skala laboratorium menggunakan jar test dengan variabel rasio penambahan koagulan Al2(SO4)3 sebesar 0,5%; 1%; 2%; dan 4%. Pada koagulasi-flokulasi dilakukan pengadukan cepat 100 rpm selama 1 menit dan pengadukan lambat 30 rpm selama 20 menit. Kemudian hasil pengadukan diendapkan selama 30 menit. Hasil penelitian menunjukkan bahwa koagulan Al2(SO4)3 1000 ppm dengan rasio 2% efisien dalam menurunkan nilai COD sebesar 42,86% dan nilai BOD sebesar 71,02%, sedangkan rasio 4% efisien dalam menurunkan nilai pH sebesar 3,75%, nilai TDS sebesar 9,76%, nilai TSS sebesar 25,19%, nilai kekeruhan sebesar 43,99%, dan kandungan minyak/lemak sebesar 20,83%.

Ikan nila merupakan komoditas ikan air tawar yang memiliki nilai ekonomis tinggi di Indonesia dan memiliki prospek usaha yang menjanjikan. Salah satu kendala penting dalam memproduksi ikan nila adalah tingginya harga pakan yang masih mengandalkan pasokan dari luar negeri. Alternatif bahan utama untuk pakan ikan nila yang ekonomis adalah ampas tahu dengan kandungan protein >20%. Tujuan penelitian ini adalah untuk mengetahui rasio ampas tahu terhadap kualitas produk pakan ikan nila sesuai dengan SNI 01-7242-2006 tentang pakan buatan untuk ikan nila Oreochromis sp. pada budidaya intensif. Metode pembuatan pakan ikan nila dilakukan dengan mencampur ampas tahu dengan variasi rasio 50%, 60%, 70%, dan 80%, dengan tepung ikan, tepung jagung, dedak halus, dan vitamin mix. Berdasarkan hasil penelitian, menunjukkan bahwa formulasi terbaik produk pakan ikan nila yaitu pada rasio penambahan ampas tahu sebesar 50% dari berat campuran.
