Securitization, Desecuritization, and Resecuritization of Labor Issues in Saudi Arabia
Authors: Hanafi Muhammad Riza , Noviryani Mely
Published: April 2024

The presence of Indonesian Workers (TKI) abroad, especially in the Middle East Region, is between the devil and the deep sea. Apart from reducing the government's responsibility to improve the economy by providing job opportunities, their presence also adds to the country's foreign exchange. However, on the other hand, the presence of TKI also adds to the problems caused by the lack of adequate legal protection, inadequate security and welfare guarantees, as well as the ups and downs of Indonesia's bilateral relations with the countries where they work as a result of the problems caused by the TKI themselves. Several policies related to sending migrant workers to the Middle East have been adopted since the time of President Susilo Bambang Yudhoyono. However, a firm policy was only taken during the administration of President Joko Widodo with the issuance of Minister of Manpower Decree number 260 of 2015 which stopped and prohibited the placement of Indonesian workers with individual users in Middle Eastern countries. This policy can also be seen as a policy that is outside the norm considering that the Middle East is the most popular region for migrant workers. This research attempts to explain how the ups and downs of the TKI issue are seen from a security perspective using a constructivist approach. This process, which the Copenhagen School calls securitization, attempts to place threats and objects that must be secured as products of the process of social interaction. This research will also look at how securitization occurs which is then followed by desecuritization and in its development becomes resecuritization.

Published: April 2024

The issue of human security in the digital era has garnered attention in line with technological advancements. The threats to individual privacy and security have become increasingly evident, particularly following the hacking incident by Bjorka in September 2022 in Indonesia. This research applies the concept of human security within the context of digital security, highlighting the inequalities in access and vulnerabilities in online privacy. The Bjorka case reflects the complexity of human security, encompassing freedom from fear, freedom from want, and the freedom to live in dignity concerning the fundamental rights of individuals in human security. The aim of this study is to understand the privacy breaches and data hacking conducted by Bjorka and its impact on the human security of Indonesian citizens, especially from the perspective of digital security. This case study research employs interviews with key respondents from diverse backgrounds, who may have been victims of Bjorka's hacking. The study finds that digital security is not only related to technical aspects but also involves disrupted human security issues, pertaining to basic human rights, access limitations, and the gender identity of individuals involved in the digital world.
Reverse Engineering a Multiple-Choice Test Blueprint to Improve Course Alignment
Authors: Petrovic-Dzerdz Maristela
Published: April 2024

Large introductory classes typically reflect courses that cover a broad landscape of learning and necessitate assessment formats that are efficient and reliable, making multiple-choice (MC) tests a good option. Designing a good quality MC test requires reflection on the appropriateness of the assessment format, designing a test blueprint, and writing MC questions following item-writing guidelines that align with course learning objectives and teaching/learning strategies. It is a time-consuming endeavour that often requires a group of question writers who are experts in the domain—both of which can be challenging considering the demands of teaching in higher education. Sometimes we want to adopt or adapt existing MC tests that we have access to. I suggest a five-step “reverse engineering” analytical process for selecting questions from existing MC tests to utilize in our course assessment, emphasizing the alignment process. In one of the steps, we will refer to the Taxonomy Table, a practical two-dimensional aid proposed by Anderson and Krathwohl (2001), to select the questions that cover a cognitive dimension landscape. The outcome of this process provides an effective visual representation of the alignment and enables us to decide on the utility of questions for the context of our unit and assessment objectives.

The qudit Pauli group: non-commuting pairs, non-commuting sets, and structure theorems
Authors: Sarkar Rahul , Yoder Theodore J.
Published: April 2024

Qudits with local dimension d>2 can have unique structure and uses that qubits (d=2) cannot. Qudit Pauli operators provide a very useful basis of the space of qudit states and operators. We study the structure of the qudit Pauli group for any, including composite, d in several ways. To cover composite values of d, we work with modules over commutative rings, which generalize the notion of vector spaces over fields. For any specified set of commutation relations, we construct a set of qudit Paulis satisfying those relations. We also study the maximum size of sets of Paulis that mutually non-commute and sets that non-commute in pairs. Finally, we give methods to find near minimal generating sets of Pauli subgroups, calculate the sizes of Pauli subgroups, and find bases of logical operators for qudit stabilizer codes. Useful tools in this study are normal forms from linear algebra over commutative rings, including the Smith normal form, alternating Smith normal form, and Howell normal form of matrices. Possible applications of this work include the construction and analysis of qudit stabilizer codes, entanglement assisted codes, parafermion codes, and fermionic Hamiltonian simulation.

Published: April 2024

The dynamic relationship between tourism and BeerLao export in Laos is investigated in this article. It provides an in-depth look into the studies that have been conducted showing the various correlations between inbound tourism and economic performance of various countries. Laos is a small landlocked Southeast Asian country with a rich cultural past, magnificent natural beauty and a rising economy despite its small size. Agriculture, particularly rice production, is the economy’s mainstay, although other industries including as manufacturing and services are slowly expanding. The most widely known Laos brand is BeerLao, a distinctive beer label occupying almost 100 % of the country’s market. The current paper explores BeerLao’s history, production, marketing strategies and export destinations, as well as the elements that contribute to its export success - specifically tourism. It seems that the pre-pandemic expansion of BeerLao’s success in the world and inbound tourism dynamics of the country are correlative and have mutually beneficial relationship. The research looks into how tourism might have affected BeerLao’s export volumes and vice versa in pre-pandemic era. The study underlines the importance of tourism and beer exports to the Laotian economy and recommends crucial areas for future investigation. The study intends to provide insights into the economic and cultural significance of tourism and beer exports in Laos, as well as provide meaningful insights to policymakers, investors, and other stakeholders about the potential benefits and problems of these businesses. The study also provides a foundation for further studies of the topical area for Laos products and their possible marketing strategies in regional and world markets.
The Role of Science in Socio-Economic Development
Authors: Kleeva L. P.
Published: April 2024

The article examines the reasons for the low innovative activity of domestic enterprises, taking into account the development of Russian science, which is still effective. The aim of the study is to identify ways to ensure a more active impact of research activities on the level of innovation and efficiency of social production, in order to improve the quality of life for the population and develop the social sphere. The originality of the approach used in this article lies in its application of methodological principles and conclusions drawn within the framework of the theory of organizational knowledge management. Specifically, the author draws on the classification of this knowledge management theory into non-formalized and formalized knowledge, and identifies four types of transformation: socialization, externalization, combination, and internalization. Additionally, the article concludes that a continuous and cyclical process is necessary for knowledge to pass through these four stages in a sequential manner. It has been concluded that one of the main reasons for the low innovation activity in our country and the low efficiency of our social production is due to the linear nature of the scientific and innovative process in Russia. This is because there is a lack of feedback between the real economy and society and the field of research and development (R&D). In other words, there is an inefficiency in the process of internalizing knowledge within the domestic economy, and the externalization phase is almost completely absent. Therefore, ensuring the fullness and continuity of this process, based on four sequential types of knowledge transformations, can lead to an intensification of innovation in Russia and an increase in efficiency in the functioning of our domestic economy and society. This in turn would contribute to improving the quality of life for our population.

Authors: Habiburrahman Muhammad , Rakasiwi Muhammad Ilham Dhiya
Published: April 2024

The incidence of tuberculosis (TB) infection in multiple organs outside the lungs is of particular concern. We present the case of a 48-year-old woman with a history of pulmonary TB who had a gradual loss of consciousness in one day, worsening shortness of breath, and a cough with green phlegm two weeks before admission. She had been undergoing five days of TB treatment with the drug-sensitive TB treatment regimen. The genital examination revealed a whitish mass in the paraurethral area, which impaired her urination. Blood gas analysis showed respiratory acidosis, and a chest X-ray suggested pulmonary TB and concurrent community-acquired pneumonia. She was diagnosed with extrapulmonary tuberculosis (EPTB) in the central nervous systems and urogenital sites. To treat her lifethreatening EPTB, she received crystalloid infusions, oxygen supplementation, ampicillin-sulbactam (converted to meropenem the next day), an oral fixed-dose combination antituberculosis therapy, pyridoxine, N-acetylcysteine, ursodeoxycholic acid, Curcuma, bisoprolol, proton pump inhibitor, and antiemetics. Additionally, she was inserted with a urethral catheter and a nasogastric tube to assist her urination and nutritional intake. Our facility was a subdistrict hospital and had a limited capacity for diagnosing and treating EPTB due to a lack of advanced intensive care units, blood and sputum cultures, and laboratory panels. After her two-day hospital admission to ICU for stabilisation, she was referred to a higher-level hospital with more advanced pulmonary treatment overseen by a multidisciplinary team. Our resource limitations highlight the importance of being
EXCEPTIONAL LONG-TERM SURVIVAL OF AN ELDERLY PATIENT WITH METASTATIC SMALL CELL NEUROENDOCRINE CARCINOMA OF THE CERVIX – A CASE REPORT
Authors: Ho Yun Yi , Yuen Hiew Nia Wei , Fuang Ho Gwo
Published: April 2024

Small cell neuroendocrine cervical carcinoma (SCCC) is known for its aggressive nature and poor prognosis. There are no standard treatments so small cell lung cancer treatments are often referenced due to their similar morphology. Typical treatment options include a combination of external beam radiotherapy and brachytherapy for localised disease and palliative chemotherapy for advanced disease. The 5-year survival rate for patients presenting with advanced disease is dismal, around 0–14%. Here, we report a case of a 75-year-old woman who was diagnosed with small cell neuroendocrine cervical carcinoma (SCCC) in 2015. She presented with locally advanced SCCC with vaginal involvement, as well as solitary lung and peripancreatic metastases. She was treated with a combination of chemotherapy, chemoradiation and stereotactic radiotherapy, followed by maintenance etoposide, and achieved a very long-term survival. The patient continues to survive today.

Published: April 2024

Malocclusion is an abnormal occlusion with regard to the position of the teeth and shows varied prevalence in different parts of the world. Crowding and spacing of teeth are two common features of malocclusion and are described as a lack or excess of space between the teeth. This study was conducted to evaluate the prevalence of crowding and spacing of teeth and their severity among Malaysian adults aged 18–25 visiting our institution, as well as their association with gender. A total of 150 adult patients were evaluated for crowding and spacing using the Boley caliper intra-orally. The severity of crowding and spacing was also noted. The study included Malay (70%), Chinese (25%), and Indian (5%) participants. Descriptive statistics were done and it was observed that crowding was more common in the mandibular arch (80%), whereas spacing was a common malocclusion found in the maxilla (14%). Based on the severity of crowding, it was observed that mild crowding (1-3 mm) was most frequent in both the maxilla (45%) and mandible (53%). However, in terms of spacing, moderate spacing (4-6 mm) (5.3%) was common in the maxilla; whereas in the mandible, mild spacing (1-3 mm) (9.3%). The Chi square analysis did not reveal any significant association between crowding and spacing with gender. Based on these results, it can be concluded that crowding is a common malocclusion affecting the mandibular arch, whereas spacing is common in the maxilla in the young Malaysian population visiting our institution. Both of these malocclusions were of the milder type and did not show any association with gender in our study population Studies conducted on a larger population are required to determine the association of these traits between genders and races in our population.

Peritoneal dialysis-related peritonitis remains the most common complication and a key barrier to peritoneal dialysis’ long-term success. The present study aimed to report on the incidence of peritonitis and clinical outcomes in CKD patients on CAPD at a hospital in Vietnam’s south and evaluate the peritoneal membrane transport status before and after peritonitis therapy. This study was a cross-sectional study involving 141 participants sampled from the warded adult patients at An Giang center general hospital, in Vietnam. Peritonitis rate was measured in terms of incidences per patient-year. Dialysis fluid was drawn under aseptic conditions and treated using a culture approach to identify bacteria. The response treatment time for each episode of peritonitis after receiving empirical antibiotic medication. We use Peritoneal Equilibration Test (PET) to determine the peritoneal transport status. Peritonitis was found in 29.8% of the cases. The number of episodes of peritonitis per patient-year was 0.035. Negative bacteria account for 81.0 percent of all cases tested. It took an average of 3 to 5 days for a clinical response. Before and after peritonitis, there was no statistically significant connection between transport status groups. The rate of peritonitis identified in this study was significantly lower than that recommended by the International Society for Peritoneal Dialysis (ISPD) recommendations. More research is needed to fully understand the variables that influence the clinical outcomes of peritonitis and the remaining function of the peritoneal membrane.

Published: April 2024

Sporotrichosis is regarded as the most common subcutaneous fungal mycosis, which occurs following traumatic inoculation of Sporothrix schenckii complex. Albeit rare, sporotrichosis, also known as 'rose gardener's disease', has been reported to involve children whereby active or passive transmission through a vector such as domestic animals has been identified as the main culprit. Herein, we report sporotrichosis in a pair of siblings who presented to the outpatient Otorhinolaryngology clinic in University Malaya Medical Centre with a lower lips skin lesion and submental swelling after kissing their domestic cat. Sporotrichosis was diagnosed following the fungal culture of the skin scrapings of the lower lip’s pustular lesions. Prompt treatment with oral itraconazole (8 mg/kg/day) for six weeks showed the resolution of symptoms. We highlight the pathophysiology of zoonotic sporotrichosis and the mode of management of this entity. Additionally, the management of sporotrichosis should include the veterinarian's assessment of the infected animal.

THE DARK SIDE OF BIGUANIDES: A CASE REPORT ON METFORMIN-ASSOCIATED LACTIC ACIDOSIS (MALA)
Authors: Fu Jing Hui , Moi Zjen Pang , Zulkifli Ahmad Zhafir
Published: April 2024

Metformin-associated lactic acidosis (MALA) is a rare but potentially fatal complication that can occur in a patient on metformin, who had a sudden reduction in the renal function resulting in a raised serum metformin level. We describe a case of MALA who survived with prompt haemodialysis. An elderly female with diabetes on metformin presented with gastrointestinal losses, lethargy and confusion. She was in circulatory shock and despite an aggressive fluid regime, she remained acidotic with an increasing lactate level of > 15 mmol/L. After endotracheal intubation, she was referred to tertiary centre for haemodialysis. Her serum lactate level rapidly fell to a satisfactory range and a progressive recovery followed. We are highlighting this case for its rarity and to serve as a guidance on the early recognition of MALA for fellow clinicians. Despite the high mortality rate, MALA is reversible, and we urge clinicians to expedite haemodialysis as definitive treatment.
VIRTOPSY AS A BREAKTHROUGH IN NON-INVASIVE AUTOPSY: ITS PRINCIPLES AND POTENTIAL OF APPLICATION IN DEVELOPING COUNTRIES DURING THE COVID-19 PANDEMIC
Authors: Habiburrahman Muhammad , Wardoyo Muhammad Prasetio , Yudhistira Aria
Published: April 2024

Autopsy practice is often limited due to the risk of infection transmission and family objections. As an alternative, virtual autopsy (virtopsy) is proposed, which uses minimally invasive radiology techniques such as postmortem CT scan (PM-CT) and PM-MRI. However, there is a scarcity of literature comprehensively summarizing this topic. Therefore, this review article discusses the advantages and limitations of virtopsy in developing countries during the COVID-19 pandemic, along with ethical issues and a proposed algorithm for postmortem imaging. Virtopsy improves the sensitivity (93%) and specificity (83%) of diagnoses and offers several advantages, such as faster identification, good foreign body detection, three-dimensional reconstruction, and non-invasiveness. Limitations include difficulty in determining infection status and assessing internal organ characteristics, operator dependence, insufficient legal basis, and high costs. During the COVID-19 pandemic, this article compiles twenty-one studies from 2020 to 2022 that used virtopsy to investigate 191 cases of COVID-19 infection resulting in death. The studies were conducted in various countries, with only two developing countries [Brazil (n = 3) and India (n = 1)] reported to have used it. Most of the studies used PM-CT, while others used postmortem ultrasound, PM-MRI, and PM chest X-ray. Virtopsies were mostly performed within 24 hours. The age range of the deceased individuals investigated using virtopsy was between 11 and 99 years old, with males being predominant. Virtopsy was mostly used for triage or screening for conventional autopsy (CA) as well as adjuvant/complement to CA. In summary, virtopsy has potential benefits for developing countries during and after the COVID-19 pandemic, making it a valuable investment despite its limitations.

COVID-19 is a highly contagious disease that caused a worldwide pandemic in 2020. Medical students are public advocates for COVID-19 vaccination to achieve herd immunity. Our objective is to ascertain the level of knowledge, attitude, and practice toward COVID-19 immunisation among medical students in Malaysia. The online study included four public universities in Peninsular Malaysia: Universiti Putra Malaysia, International Islamic University Malaysia, Universiti Sains Malaysia and Universiti Sains Islam Malaysia. Data collected include sociodemographic characteristics, history of COVID-19 infection, knowledge, attitude and practice towards COVID-19 immunisation. Analytical statistics were analysed with IBM Statistical Package Statistical Package for the Social Science (SPSS) v27.0 using Pearson chi-square or Fisher’s exact test (significant if p < 0.05). From the total of 427 respondents, 60.2% had good knowledge whereby clinical students 67.0% had a higher proportion of good knowledge as compared to preclinical students 53.5% (p = 0.004). Respondents in the age group of 21 to 24 years old (p < 0.001) and 25 to 29 years old (p = 0.016), and Indian ethnicity (p = 0.006) were more likely to have good knowledge. Respondents registered in Malaysia’s National COVID-19 vaccination program were considered as having a positive attitude (n = 264, 61.8%). A vaccination rate of 100% was observed. In conclusion, 60.2% of medical students had good knowledge, 61.8% had a positive attitude and 100% were vaccinated in these four public medical schools in Malaysia. Sociodemographic factors (age group and Indian ethnicity) have an association with only good knowledge but none with the level of attitude and practice towards COVID-19 immunisation.

Early sowing can help summer crops escape drought and can mitigate the
impacts of climate change on them, but it exposes them to cold stress
during initial developmental stages, which has both immediate and
long-term effects on development and physiology. To understand how early
night-chilling stress impacts plant development and the yield, we
studied the reference sunflower line XRQ under controlled,
semi-controlled and field conditions. We performed high-throughput
imaging of the whole plant parts and obtained physiological and
transcriptomic data from leaves, hypocotyls and roots. We observed
morphological reductions in early stages under field and controlled
conditions, with a decrease in root development, an increase in reactive
oxygen species content in leaves and changes in lipid composition in
hypocotyls. A long-term increase in leaf chlorophyll suggests a stress
memory mechanism that was supported by transcriptomic induction of
histone coding genes. We highlighted leaf transcriptomes in
cold-acclimation genes such as chaperone, heat shock and late
embryogenesis abundant proteins. We identified genes in hypocotyls
involved in lipid, cutin, suberin and phenylalanine ammonia lyase
biosynthesis and ROS scavenging. This comprehensive study describes new
phenotyping methods and candidate genes to understand phenotypic
plasticity better in response to chilling and study stress memory in
sunflower.

Mpox is a zoonotic disease historically reported in Africa. Since 2003,
limited outbreaks have occurred outside Africa. In 2022, the global
spread of cases with sustained interhuman transmission and unusual
disease features raised public health concerns. We explore the mpox
outbreak in Rio de Janeiro (RJ) state, Brazil, in an observational study
of mpox-suspected cases from June to December 2022. Data collection
relied on a public healthcare notification form. Diagnosis was
determined by MPXV-PCR. In 46 confirmed cases, anti-VACV IgG was
determined by ELISA, and seven MPXV genomes were sequenced. A total of
3,095 cases were included, 816 (26%) with positive MPXV-PCR results.
Most positive cases were men in their 30s and MSM. A total of 285 (35%)
MPXV-PCR+ patients lived with HIV. Eight were coinfected with
varicella-zoster virus. Anogenital lesions and adenomegaly were
associated with the diagnosis of mpox. Females and individuals under 18
represented 9% and 5% of all confirmed cases, respectively, showing
higher PCR cycle threshold values and fewer anogenital lesions than
adult men. Anti-VACV IgG was detected in 29/46 (63%) patients. All
analyzed sequences belonged to clade IIb. In RJ state, mpox presented a
diverse clinical picture, represented mainly by mild cases with low
complication rates and prominent genital involvement. The incidence in
females and children was higher than usually reported. The observation
of a bimodal distribution of Ct values, with few positive results, may
suggest the need to review the diagnostic criteria in these groups.
Enhanced Multi-objective Optimization Model for Bridge Performance Assessment and Prediction, Based on Improved PCA, K-means Clustering, and Kaplan-Meier Survival Algorithm

Published: April 2024

The research proposes a hybrid algorithm model that combines
model-driven and data-driven approaches for the direct application of
bridge health monitoring technology in bridge management. This
comprehensive study encompasses a series of analytical techniques and
methodologies to build a multi-objective optimization model for bridge
performance assessment and prediction. It focuses on the processing of
multi-source heterogeneous data, selection of key sub-parameters using
Principal Component Analysis (PCA), enhanced K-means clustering
analysis, determination of structural component target thresholds,
time-dependent survival probability analysis, regression fitting, and
timing prediction of the bridge system for both the components of
double-layer truss arch bridge and the bridge system. The initial phase
of the study concentrates on the diversification and decentralization of
monitored data from various sources, integrating and cleaning data
obtained from different sources to ensure data quality and consistency.
PCA technique is applied to identify key sub-parameters that have
significant impacts on the performance of structural components.
Enhanced K-means clustering analysis is carried out to effectively group
and classify the identified key sub-parameters. Numerical simulations,
including structural nonlinear analysis, are conducted to determine the
target thresholds of bridge structure, providing important benchmarks
for performance evaluation. Finally, a multi-parameter regression model
is used to evaluate and update the performance of the bridge structure,
taking into account survival probability (using the Kaplan-Meier
method), maintenance history, and material deterioration to estimate the
most critical time for the bridge system. A case study is conducted to
validate the suggested comprehensive algorithms for a double-layer truss
arch combination bridge, which contributes to enhancing performance
evaluation and predicting the most critical time for structural
components and the bridge system in the bridge management and
maintenance practices. It should not be ignored that, the accuracy and
reasonability of bridge structure system performance evaluation and
prediction depend largely on the selection of target thresholds.

Published: April 2024

Cell viability and cytotoxicity assays play a crucial role in drug
screening and evaluating the cytotoxic effects of various chemicals. The
quantification of cell viability and proliferation serves as the
cornerstone for numerous in vitro assays that assess cellular responses
to external factors. In the last decade, several studies have developed
guidelines for defining and interpreting cell viability and cytotoxicity
based on morphological, biochemical, and functional perspectives. As
this domain continues to experience ongoing growth, revealing new
mechanisms orchestrating diverse cell cytotoxicity pathways, we suggest
a revised classification for multiple assays employed in evaluating cell
viability and cell death. This classification is rooted in the cellular
compartment and/or biochemical element involved, with a specific focus
on mechanistic and essential aspects of the process. The assays are
founded on diverse cell functions, encompassing metabolic activity,
enzyme activity, cell membrane permeability and integrity, ATP content,
cell adherence, reduction equivalents, dye inclusion or exclusion,
constitutive protease activity, colony formation, DNA fragmentation and
nuclear splitting. These assays present straightforward, reliable,
sensitive, reproducible, cost-effective, and high-throughput approaches
for appraising the effects of newly formulated chemotherapeutic

Background The increasing use of intracardiac echocardiography
(ICE) in the ablation of premature ventricular complexes (PVCs) has
raised questions about its true efficacy and safety. Objective
To evaluate the long-term outcome and periprocedural complications of
PVCs ablation with and without ICE. Methods This retrospective
study collected the periprocedural complications and PVC burden post
ablation. The risk factors of PVC recurrence was further explored.
Results The study included patients treated without ICE
(control group, n=451) and with ICE (ICE group, n=155) from May 2019 to
July 2022. The ICE group demonstrated significantly lower fluoroscopy
times and X-ray doses. There were no major complications in the ICE
group, and the difference in the occurrence of periprocedural
complications between the groups was not statistically significant
(p=0.072). The long-term success rates were similar for the control and
ICE groups (89.6% and 87.1%, respectively). The origin of PVCs was
identified as the independent factor for ablation success.
Conclusions The use of ICE did not confer an advantage with
regard to long-term success in PVCs ablation. To thoroughly evaluate the
safety and effectiveness of ICE in PVCs ablation, a prospective,
multicenter, randomized study is warranted.

Magnesium ferrite (MgFe2O4) particles were synthetized by sol-gel method and
used in the decolorization of the Acid Violet 109 (anthraquinone dye, AV109)
water solutions' by combination of adsorption and heterogeneous Fenton
process. The material's morphology and elemental analysis of the surface
were revealed by Scanning electron microscopy and Energy Dispersive
Spectroscopy (SEM/EDS). The X-Ray Diffraction (XRD) technique was used to
analyze the crystallographic phase. In the first part of the decolorization
experiment, the adsorption ability of the synthesized particles was
investigated. During the adsorption study influence of pH was investigated.
In the second part of the decolorization experiment, the effects of the
various parameters on the Fenton process were studied such as the initial
concentrations of hydrogen peroxide, dye, and magnesium ferrite particles.
Influence of magnesium ferrite particles structure, pH value and reaction
temperature were also investigated. The decolorization reaction was followed
by UV-Visible (UV-Vis) spectrophotometry. At optimal conditions, the dye
decolorization was 99.1% (55.4% by adsorption and 43.7% by the Fenton
process). Both the adsorption and the Fenton process obey second-order
kinetics.

The process of making salt is still done manually by filling water into reservoirs and plots which require salt farmers to visit their farms periodically. This is mainly because the speed of the salt crystalization process is always inconsistent due to salt concentration in seawater and the weather. This study aims to build a new prototype of a water level monitoring system in reservoirs and plots in salt ponds then measure the water's salinity value, which will be reported to the farmers. The method used in this research is prototyping, which includes system requirement analysis, rapid design, prototype building, system evaluation, and system  improvement. The system was tested using the black box method, namely testing all system functionality and determining user satisfaction with questionnaires. The functionality test results, including monitoring the water level and the pump control, show that the prototype functions correctly. The designed system can send information in the form of water level values in reservoirs, water levels in plots, and salinity values with linear sensor accuracy with measurement results with conventional measuring instruments with standard error values of 0.485, 0.44, and 0.72, respectively. Applying this system will ease farmers’ monitoring of water levels and controlling irrigation in reservoirs and plots.
