The research results explain that strong, consistent, and non-discriminatory law enforcement is a key element in ensuring the existence of principles of justice and legal certainty. It also has the potential to benefit society through deterrence, which can discourage individuals from engaging in corruption. Additionally, it contributes to building public trust in law enforcement efforts and law enforcement agencies. Consequently, public support for law enforcement institutions is strengthened. The development of this concept in anti-corruption law is expected to help recover state losses caused by corruption. Moreover, this punitive concept also offers several benefits in achieving the objectives of penalizing offenders. With a clear obligation to repay restitution without compromise, an offender will work under state supervision to generate funds used to cover the losses resulting from their actions.

THE ANALYSIS OF THE MIRROR PRAYER POEM IN HÜSEYIN AKKAYA'S BOOK POEMS PASSING THROUGH THE MIRROR
Authors:   Kastamonu University, Turkey, Bayram A. , Koç A.
Published: January 2024

Hüseyin Akkaya, born in Sivas in 1955, worked as a professor at Cumhuriyet University since 2004 and retired. In addition to being an academic, his interest in poetry has never ended due to his childhood curiosity. After his first poem, Beli Gül, he wrote his poems with the theme of "mirror". “When I started writing poems centered on the mirror nine years ago, I did not expect that there would be so many of them."I think my poem, "Living in Mirrors", which I first wrote in 2012, must have been born from a fertile source because it paved the way for other mirror poems." He describes his arrival in this way. "Mirror", which has an important place as a symbol in poetry, has been used by many poets from divan literature to the present day. The "Mirror" symbol has appeared in poems both in mystical and human terms. Akkaya, on the other hand, wrote his poem called "Mirror Prayer" as a Sufi style in his book where he compiled his poems on the symbol of "mirror". Roman Ingarden and Nicolai Hartmann are two important names in the ontological analysis method, which is one of the poetry analysis methods. Ingarden stands out in dividing assets into layers, and Hartmann stands out in dividing these layers into real and irreal asset areas. Under the guidance of this information, İsmail Tunalı examined the layers of existence in his book titled Art Ontology. The poem "Mirror Prayer" mentioned in this study was analyzed ontologically according to the layers of existence in İsmail Tunalı's book titled Art Ontology.

Analytical Studies on the Radionuclide Levels of Sediment and Water in an Agricultural Environment in the Egyptian Delta
Authors: Shady R. , A. Elzain A. E.
Published: January 2024

This paper is an environmental investigation of the concentration values of radioisotopes and hazardous elements, aimed to shed light on industrial pollution and the effect of using fertilizers in the period of irrigation water drainage from cultivated lands, especially in the River Nile, irrigated, and draining channels in the middle portion of the Egyptian river delta. Different samples were analyzed, both for water and sediment. Many physical and chemical characteristics of samples were investigated. Among them are the quantitative measure of the acidity or basicity of aqueous or other liquid solutions (pH), grain size, and the total organic matter content (TOM) have been determined for sediments. pH and TDS, beside other types of pollutants, were determined for water samples. The water and sediment samples pH are slightly alkaline. The mean value of TDS for water samples is 488 mg/l, while he usual TDS value in river is 500 mg/l. The TOM values show that the sediment samples are poor in organic matter content. The bicarbonate range in the water samples is smaller than the same range in river water. The levels of Ra-226, Th-232, and K-40 activity in sediments are highly correlated. Natural radionuclides seem to correlate with the artificial Cs-137 in sediment. For this peruse, a 240 cm3 high-purity germanium reagent Type-B was used to quantify the levels in each sample with a relative accuracy of 50 %. The radioactive element K-40 is having a typical value of 12.5 Bq/kg. The concentrations of both Cu beside Zn in water samples is smaller if compared with values that quoted by the WHO, the US-EPA, and the EC. It was also found that the average levels for both Cd and Mn are found to be close to the internationally recommended levels. The water and sediments in the southern part of the canal contain higher concentrations of heavy metals and radioactive isotopes than in the rest of the canal.
The Effect of Sr2+ and Fe3+ Cations and the Stirring Speed on The Precipitation of Barium Sulfate in a Batch System

Published: January 2024

The batch system investigation explored the effect of Sr2+ and Fe3+ cations and the stirring speed on the characteristics of precipitated barium sulfate. A series of experiments were conducted to evaluate the rate of barium sulfate precipitation in laboratory equipment from brines containing barium ions (3500 ppm) and varying amounts of Sr2+ and Fe3+ ions (10 and 20 ppm). Kinetic analysis was also performed to explore how stirring speeds (240 and 480 rpm) affect barium sulfate scales' crystallization by increasing the stirring speed and promoting Sr2+ and Fe3+-cation solubility while decreasing the precipitation rate. All solid crystals obtained were mostly pure barite, as the X-ray diffraction (XRD) method confirmed. The SEM micrograph of barite morphology revealed particles with tablet-shaped crystals 2 to 5 nm in size. With the presence of Sr2+ and Fe3+-cation, the shape of barium sulfate was modified into spherical tablets or flower-like clusters of tablets. Meanwhile, the morphological changes could result from increased stirring rates. Moreover, the kinetic results yielded a general reaction rate equation that might be used to estimate barium sulfate deposition in pipelines for various brine, supersaturation, and mixing time durations.
EFEK BLIND FEEDING UNTUK MENINGKATKAN PERTUMBUHAN POST LARVA UDANG VANAME KEPADATAN TINGGI DAN PENGARUHNYA TERHADAP KUALITAS AIR [The Effect of Blind feeding to Increase Post Larva Growth of High-density Vaname Shrimp and Their Effect on Water Quality]

Published: January 2024

Blind feeding is a feed dosage of feeding shrimp cultivation that is carried out without looking at the shrimp biomass conditions for the first 30 days. The goal is to ensure that shrimp get adequate feed intake in the early stages of growth, yet blind feeding often has an impact on the decline in water quality as a result of overfeeding. The study aimed to evaluate the effect of the blind feeding method on the growth of vaname shrimp (Litopenaeus vannamei) and water quality. The treatments to be tested were the quantity of feed: (a) 123.5 kg/100,000 shrimp; (b) 148.2 kg/100,000 shrimp; (c) 172.9 kg/100,000 shrimp; (d) 197.6 kg/100,000 shrimp; and (e) 222.3 kg/100,000 shrimp. The dose range of blind feeding referred to the habits applied by the cultivators in the field. The shrimp used was PL 12 with a density of 1,000 individuals/m3, which were maintained for 30 days in an aquarium container of 50 x 40 x 30 cm or a volume of 50 liters. The feed was given four times a day at 8.00, 12.00, 16.00, and 20.00. The results of the study showed that the blind feeding feed dosage had a significant effect on the absolute growth of shrimp and total ammonia nitrogen (P < 0.05). The blind feeding treatment (c), which was 172.9 kg/100,000 shrimps, produced the best growth with a lower total ammonium nitrogen so it is recommended that it be applied in shell cultivation in the first 30 days of maintenance.

Published: January 2024

Bakasang bia garu is a clam-based fermented product processed by the people of the Babar Islands, Maluku. Uncontrolled processing allows the presence of unwanted bacteria in these local food products. Preservatives added in the processing of bakasang bia garu are very diverse. This study aims to isolate and characterize lactic acid,  halotolerant, and coliform bacteria from bakasang bia garu which are processed using different preservatives. Lactic acid bacteria were isolated using de Man Rogosa and Sharpe Agar (MRSA) media while halotolerant and coliform bacteria used Mannitol Salt Agar (MSA) and Eosin Methylene Blue Agar (EMBA) media, respectively. Characterization was carried out macroscopically and microscopically. The results showed that lactic acid bacteria were only found in bakasang with synthetic salt and vinegar preservatives of 3.5x103 CFU/g which was dominated by Pediococcus pentosaceous. Halotolerant and coliform bacteria have diverse characteristics that belong to the genera Staphylococcus, Escherichia, and Enterobacter. Bakasang bia garu needs to optimize its controlled processing to improve the quality of this local food product in the future

Published: January 2024

The Restored  Forest (RF) in Bodogol, Gunung Gede Pangrango National Park (GGPNP) is located in the degraded   lowland forest area. The Bodogol RF constituted the area of the ecosystem restoration program, where the initial tree planting was carried out by Mrs. Megawati Soekarnoputri the 5th President of  the Republic of Indonesia. In that restored forest area,  a  study was conducted by establishing one hektare plots. We recorded  26 tree species and 16 families, including 14 tree species  that were used in the restoration, four cultivated species, and eight species that naturally enter the site as new arrival   (recruitment).  The total basal area was  7.47 m2/Ha and tree density was 256 trees/Ha. The mean diameter growth was 1.78 cm/year, and the highest diameter growth was Hibiscus tilliaceus (2.42 cm/year). The mean total height growth was 0.52 m/year, and the highest was Paraserianthes falcataria (0.85 m/year). The density of Toona sureni was very high (61 trees/Ha) and in the future it ay dominate the forest  will, therefore other tree species native to Mt. Gede-Pangrango should  be planted  to enrich the present restored forest so as to encourage the development of mixed  lowland or montane forests similar to the original climax forests with high species diversity.  Structurally, about 50 %  of the RF has been achieved,  but species composition  still needs further enrichment either by active intervention of planting native TNGGP species if deemed necessary or by allowing succession to take place naturally, although it will take a  very long  time.

Leaves and pitchers (fresh and dried) were extracted in 3 types of solvents (acetone, methanol, and DMSO). The samples were then analyzed with a UV-VIS spectrophotometer. The results showed that the leaf and pitcher samples had quite different results. The leaf sample showed higher results than the pitcher sample, which had a chlorophyll a (3.434a), chlorophyll b (1.311a), carotenoids (0.918a), and total chlorophyll (4.745a) content. The pitcher sample had a content of chlorophyll a (1.463b), b (0.642b), carotenoids (0.445b), and total chlorophyll (2.105b). The treatment of samples given various solvents such as DMSO, Acetone, and Ethanol showed insignificant results on the content of chlorophyll a, chlorophyll b, carotenoids, and total chlorophyll. The conclusion is that all solvents can be used to analyze pigment content.

Scientific diving has been going on for decades in Indonesia. One of the scientific diving activities is monitoring coral reef ecosystems, better known as the coral reef condition assessment methodology. However, the vastness of Indonesia’s waters is challenging to monitor coral reefs together. Therefore, one coral reef monitoring strategy is creating nodes or regional representation in various regions in Indonesia. Furthermore, strengthening the capacity of human resources through various basic training activities and advanced training. After obtaining a license, this training begins with diving training, followed by coral reef monitoring materials. The fields taught are coral reefs, coral fish, and another benthic biota

Electromagnetic noise emission is inevitable in a DC-DC converter due to the employed switching technique. In low frequency, the noise propagating through cabling and conductive media is called a conducted emission. A conducted emission consists of differential mode and common mode noise. It is advantageous to know an estimate of emission level for each mode during the design phase so that suitable mitigation can be included earlier.. This paper aims to focus on a method to estimate the differential mode noise emission of a DC-DC converter. The estimation is computed using the input capacitor complex impedance and the current that flows through it. As a study case, a boost and buck converters are used for evaluation. The estimation and measurement results are compared. Despite differences at some frequencies, the estimated and measured results generally  agree well. Because of its simplicity, the proposed method can be used as a practical tool in the EMC aspect of DC-DC converter design.

The electron transport layer (ETL) is a crucial part in perovskite solar cells (PSC) as it specifically governs the charge extraction at the perovskite/ETL interface. In this study, methylammonium lead iodide-based PSCs with an n-i-p structure were fabricated and modified by adding colloidal TiO2 into the mesoporous TiO2 film as ETL. The effect of the colloidal TiO2 addition on the PSC performance was investigated for ETL comprising different types of TiO2 particles, i.e. P25 and anatase TiO2. Despite producing lower performance than the PSC made with commercial paste, the power conversion efficiency of the PSCs could be improved with the introduction of colloidal TiO2 solution. An optimum condition was observed depending on the type of TiO2 particle, where the best performing device was achieved with colloidal TiO2 of 0.4 and 0.2 mL for P25 and anatase TiO2, respectively. The amount of colloidal TiO2 in samples with P25 overall had less impact than the samples with anatase TiO2.

The presence and establishment of invasive alien fish species is one of the biggest threats to aquatic biodiversity. The red devil, Amphilopus citrinellus, is one of the emerging invasive species and its occurrence is massively detected in common water bodies in tropical areas such as Indonesia. However, the topic remains under-reported from the small urban lakes. This study aims to present the reproductive characteristics of the fish in Situ Cilodong, a small urban lake in the country, that can be used as a principal reference for population control. The sampling was conducted in June 2021 and May 2022 using a mix of seven mesh-sized gillnets. The results of the length-weight relationship reveal that both the female and male fish perform isometric growth type. The calculated Gonad Somatic Index (GSI) and the histological analysis confirmed that the fish is a multi-spawner species. The results imply that sustainable population control efforts must include intensive catch and engage a participatory approach between the legal authority and the local fishers.
Mitigating atmospheric methane emissions from Asian rice fields: a review of potential and promising technical options
Authors: I Gusti Ayu Agung Pradnya Paramitha
Published: January 2024

Agriculture serves as a significant anthropogenic source of methane emissions. Numerous recent studies have examined the factors influencing methane emissions and have developed emission models. However, there is no a bridging review study related to methene emissions in Asia as one of the primary methane emitters. This review is divided into two manuscripts. In this first manuscript, I explore the process of methane emission and the factors that impact methane production and emissions. Meanwhile, the present state of studies conducted in various Asian countries and knowledge gaps are elaborated in the second manuscript. I elaborate several factors that influence methane production and their roles in the emission process. Further, I highlight that the gas is mostly produced in zero oxygen condition, although, a little concentration of methane also can be generated in oxic condition. This finding provides basic knowledge that contribute to the future research on methane emissions in rice field ecosystems.  Eventually, I also explore various recommended technical solutions to reduce the gas emission.
Diagnostic indications of knee joint fluid – current state ofknowledge
Authors: Turzański Damian
Published: January 2024

Synovial fluid (synovia) plays a complex role in the knee joint due to the multi-stage physiologicalprocesses taking place there. The biomechanics of the knee joint is based on the jointfluid as the main shock absorber in the system of friction forces. The diagnosis of synovialfluid is of particular importance in the process of treatment and diagnosis of the disease. Itturns out to be helpful not only to surgeons and orthopedists, but also to clinical physiotherapists.Any pathologies within the knee joint therefore directly affect the composition andbiorheology of the synovial fluid.The literature review consisted of articles collected in the following databases: PubMed and CochraneLibrary regarding changes in the composition of knee joint fluid over the last 20 years.The collected articles were divided into groups with the greatest clinical significance: cytokines, immune system cells, mesenchymal stem cells, collagen, biomarkers, enzymes, nitric oxide(NO), neurotransmitters. Each group presents the latest data on individual groups of compoundspresent in the composition of the synovial fluid of the knee joint, quantitative data ofthese substances and the role they play in the pathophysiological processes of the joint.The collected research reports allow us to observe trends in the progress of research on thesynovial fluid of the knee joint and to distinguish groups of compounds that are the area ofresearch interest in modern synovial fluid diagnostics. Cytokines that are involved in inflammatoryand immunomodulatory processes are of the greatest interest. The most importantof them belong to the groups of interleukins, extracellular matrix metalloproteinases and fibroblastgrowth factor. Studies on collagen breakdown and markers of its degradation duringosteoarthritis and in the initial stages of joint injury are also the subject of broader researchinterest in the pathophysiology of knee joint fluid. The fewest scientific reports concernedenzymes and neurotransmitters, of which only acetylcholine and choline transporters (CTL,OCT) were sparsely described in the world literature.
