The Paper industry is an energy-intensive and one of the most energy-consuming industries in Indonesia. In this study, Paper Mill energy sources come from coal and renewable energy such as black liquor as a substitute for coal and on-grid 9MW PV system are reassessed by using optimization software, HOMER. This study aims to present a feasibility study of increasing the use of renewable energy sources in Paper Mill to reduce coal consumption for more sustainability. The software HOMER is used as a tool to determine the most feasible combination of component considered in the study. It is feasible to reduce 10,84% coal consumption kg per year with the optimal renewable energy mix consisting of additional 24MW rooftop PV system and 5,94kW hydrokinetic energy from Kampar River located 6 km from the plant. Renewable fraction increased to 16%. This study result is good for sustainable growth of Paper Mill business that investments in climate and nature to support the Indonesian government in achieving net zero emissions.

Agricultural products, including root fruits, make up a large part of a person’s vital needs. Therefore, cultivating root fruits and harvesting crops without harm is one of the main tasks of agricultural events. Considering the above, it is of great importance to have information about the scientific research and scientific results achieved by our scientists in this field. To this aim, a bibliometric analysis of articles on root harvesters published in the Scopus database between 1982 and 2022 was used to understand the current state of studying cultivating agricultural products, including root fruits, and harvesting their crops and to provide references for future studies. To carry out this research different tools such as Office Excel 2021, VOS Viewer and Mapchart.net were used. The literature retrieved totaled 201 articles, of which 70% were research papers. During the last four decades, the quantity of published papers has increased significantly. For example, there were 22 papers published in 2019, 22 times increase over the number of papers published in 2002 (1 paper). It was found that the top five countries that published the most literature were China, the United States, India, the United Kingdom, and Canada, which published 44, 43, 12, 12, and 10 articles, respectively. During the chosen period 159 authors from 58 countries contributed to the given field.

Medical imaging is currently using artificial intelligence-based technologies to aid evaluate diagnostic information images, particularly in enforcing kidney stones. Artificial intelligence technology continues to develop, many studies show that deep learning is more widely used compared to traditional machine learning, so an Artificial intelligence system is needed to assist the accuracy of health diagnoses, thus helping in the field of radiology health. The aim of the research is to use artificial intelligence with deep learning models to help detect abnormalities in the kidneys. This research method is a literature review of Scopus data related to deep learning in medical imaging in detecting kidney stones. The results of using Artificial Intelligence in medical imaging can be used in diagnosing diseases including detecting Covid-19, musculoskeletal, calcium scores on Cardiac CT, liver tumors, urinary tract lesions, examination of the abdomen and kidney stones. Utilization of Artificial Intelligence in detecting kidney stones can be done with various classification models including XResNet-50, ExDark19, CystoNet, CNN, ANN. Using the right model and having a high accuracy value can help radiologists to accurately detect kidney stones.

In past few years, as indirect convection cooling equipment, heat pipes have grown in favour for a variety of uses, including heat recovery and electronics. A sensible heat is categorized as not having a filter arrangement as a “pulsating heat pipe”. It transfers heat from its evaporator to condenser portions by moving the circulating flow back and forth a reaction of its ongoing phase shift that occurs inside of it. It is difficult to truly understand how it operates since the two-phase flow is the result of combining physical and thermodynamic factors. Despite this, the PHPs have caught the interest of researchers all over the world because of its simple design and large several scenarios necessitating an elevated heat transfer rate. Presented here begins and a preface outlining several researchers’ trying to model experimental explain how PHPs work. A short tabular review of the most recent experimental investigations on PHPs is offered. Novel ideas have been explored, including the use of Nano-fluids to improve PHP performance.

The development of new technology such as internet and social media makes the future of the paper industries are getting worse. Local media does not immune from the phenomena. Serving to its communities is one of the strategy to be survive. It is done by several papers in Java Island. One of them is Suara Merdeka daily. How did this paper actualize its strategy on its framing content? Describing the frame of the information which was used to serve its communities was the main objective of this research. A framing theory and framing analysis in constructive paradigm was used to answer the problem. The content of Suara Merdeka daily was chosen purposively to get the evidence. There were some rubrics that contained the service to communities namely “Fokus Jateng”, “Liputan Khusus”, “Telisik”, “Spektrum”, “Her Spirit”, “Jalan-jalan”, “Layar”, “Trending Topic”, and “Hello Kampus”. The result showed more information framing on news than another framing. Besides, a certain education institution was published more than others. There was an unequal treatment to communities to be published in the paper. It is suggested, in the future, the paper should give the same treatment to its communities.

Increasing number of industry in Indonesia lead to produce large amount of waste. If the waste is not treated by phytoremediation, it will pollute the environment. One method to overcome this problem is phytoremediation process. Phytoremediation is the use of plant to reduce pollutants in both organic and inorganic compounds as well as to remove the contaminants. This study aims to evaluate the effectiveness of water hyacinth plant in absorbing paper industry liquid waste. Observations were made with phytoremediation of time 0, 7, 14, and 21 days with 2 treatment ie treatment covered by plastic and treatment not covered by plastic and by 4 concentration dilution ie 100% liquid waste, 75% liquid waste, 50% , and 25%. The result should that after 21 days of water hyacinth can reduce the COD level with the highest efficiency level of 1.63%, then BOD of 4.29%.
