Activated carbon adsorption has been widely used as an alternative environmental treatment to reduce metal ions, but it is less effective against heavy metals and other pollutants, including organic and inorganic compounds. Surface modification is required to increase the adsorption of activated carbon. To build up the information related to adsorption power of activated carbon modification, this study evaluated the theme relevant to adsorption of activated carbon modification using keywords "activated carbon" and "surface modification" as the data input. The database utilized for bibliometric analysis in this study was from Scopus with the help of VOSviewer software for network visualization of authorship, countries, citations, affiliations, and keywords. The analysis was carried out on February 3, 2022. The author limited the data by its year from 2013 to 2020 and the result was 262 documents. The results portrayed that the publication of activated carbon modification has been highly rocketing in the last eight years, specifically from 2019 to 2021. China is the leading country in activated carbon modification research, which results in the highest publications, most cited authors, and affiliations. Additionally, Elsevier is a publisher with the most top publications in producing activated carbon modification research articles. The keyword analysis showed that the studies related to activated carbon modification were mostly concentrated on characteristics of activated carbon, surface characteristics, adsorption, and environmental treatment. This bibliometric analysis study presented the relevant information on the surface modification of activated carbon to boost dangerous pollutant adsorption in the direction of environmental treatment.
MARDI developed the RiceFert formulation to assist in fertilizer recommendation rate for optimal paddy growth. The formulation followed an adjustable soil test–target yield equation (ST-TY) into dedicated software. The output from the RiceFert software includes a total rate of N, P2O5, and K2O fertilizer (kg/ha) and split application or straight fertilizer rate (kg/ha). Additionally, the output from RiceFert was integrated to GIS to produce maps according to the specific fertilizer recommendation rates. With interpolation techniques, thematic maps added more information, such as total area coverage according to individual classification classes. This paper discusses the overall process of fertilizer recommendation rate for paddy fields, starting with the RiceFert formulation, followed by map production using interpolation techniques according to the fertilizer recommendation output. The RiceFert strategy is expected to benefit local authorities because it offers vital information to farmers for optimal rice growth and output.
Geothermal manifes-tations of hot springs are formed due to the flow of hot fluid that comes from rock fractures that are below the surface. The nature of various rocks and the heat produced from below the surface makes the characteristics of each geothermal system different. One of them has an impact on each chemical content of the fluid that appears on the surface varies. The purpose of this research was to find out more about the condition of existing hot springs as the object of study in determining the type of fluid and functional groups manifestation geothermal hot springs of Tolok I village, Tompaso, Minahasa Regency. For determining the type of fluid laboratory tests were carried out and the results of these laboratory tests were conducted by Liquid Chemistry Plotting on the ternary plot diagram. To analyze fluid functional groups, water samples were tested using FTIR spectroscopy. The measurement of physical parameters was also carried out to support this research. The results showed that the type of fluid in the study area was chloride type with a percentage of 51% and the functional groups obtained were functional groups of amides, ketenes and carbonates.
The paper aims to review the systematic review papers in the field of Halal in accordance with PRISMA methodology. Qualitative research paper that used the systematic review –PRISMA methodology. 19 articles was founded in the research review, most of it are published in well known food and Islamic marketing journals after the year of 2015, with different percentage of adopting and applying the PRISMA methodology. This paper only consider SCOPUS database, in which there might be good research and papers published outside this database. It can be used a guide for PhD students and PhD holders in applying the PRISMA methodology.
Along with the rapid development of the city of Semarang, numerous problems have emerged, including the occurrence of flood-related natural disasters in several areas along the city's north coast, one of which is the flood. The flow of the Babon River, a component of the East Semarang drainage system, stretches from the Penggaron region in the upstream to the Genuk region in the downstream..Numerous factors affect the Babon Semarang River, including its restricted capacity due to sedimentation, the pace of land subsidence, high tides, and overflows from nearby rivers. This regulation is for figuring out how high the water will get during the rainy season, how much water the river can hold using Hec-ras, and how to handle the Babon river flood. Research Techniques for the Analysis of the Babon River Flood Control in the Karangroto-Banjardowo Area, Semarang City, starts with the gathering of secondary data, such as data on rainfall, data from rain stations, and data on the characteristics of watersheds.Using information on rainfall, channel measurement data, and the state of the channel, the planned flood discharge (R24) is calculated.The researcher will use this information to determine the anticipated rainfall for the return periods of Q 2, 5, 10, 25, 50, and 100 years.We employ the Normal Distribution, Log Normal Distribution, Pearson III Log Distribution, and Gumbel Distribution to calculate the data. Afterward, Log III distribution analysis was used since it was closer based on these calculations. he peak flood discharge (QP) value is 2.07 km³, the Q2 year is 21.82 m/sec, the Q5 year is 25.17 m/sec, the Q10 year is 27.41 m/sec, the Q25 year is 30.25 m/s, the Q50 year is 32.40 m3/s, and the Q100 year is 34.55 km³/s, according to data analysis using the Nakayashu method.Following that, it is simulated in the Hydrology Engineering Center River Analysis System (Hec-Ras) application program using the flood discharge data for the Q50 year return period.
