Authors: Fachrurrozie  , Martono S , Nurkhin Ahmad , Mukhibad Hasan , Kardoyo
Published: October 2024

Pondok pesantren are educational institutions that are expected to contribute to environmental education, especially in overcoming the waste problems. A survey by the FEB UNNES Service Team regarding waste management at the Pondok Pesantren As Salafy Al Asror showed several problems in waste management, including not yet optimal management of temporary waste, and processing of organic waste that has the potential to be reprocessed. The implementation method is training and coaching. Training methods are implemented through waste management training for cleaning teams and santri and maggot cultivation training as well as providing adequate work safety equipment. The service activity was carried out on May 18 2024 at Al Asror Vocational School with 20 male students and 10 surrounding residents. The speakers for the activity were the service team leader, kiai, and practitioners from the Semarang City Zero Waste Community (Komunals). The activity was carried out in the form of training with two material sessions, namely waste management and maggot cultivation. The activity was opened by the cottage caretaker, KH. Al Mamnuhin Kholid. The first material was delivered by Drs. Fachrurrozie, M.Si. which emphasizes the importance of managing waste so that it can have a positive impact on the surrounding environment. The second material was delivered by Dr. Inaya Sari Melati, M.Pd. and Luthfan Faladias. Based on the results of the pre-test and post-test that have been carried out, it can be stated that there has been a significant increase in participants' knowledge in waste management and maggot cultivation.

Authors: Negro DanaRose , Yazdani Mishaal , Benitez Lindsay , Kenyon Chén C. , Fiks Alexander G. , Vasan Aditi
Published: October 2024

OBJECTIVES

The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) and Supplemental Nutrition Assistance Program (SNAP) provide essential nutrition support for low-income families. However, many eligible families do not receive or fully redeem these benefits. We aimed to understand current and former WIC and SNAP beneficiaries’ perceptions of and suggestions for improving both programs.

METHODS

We conducted semistructured phone interviews with caregivers of pediatric patients who were current or former WIC and SNAP beneficiaries at 2 academic pediatric primary care clinics. Interviews were recorded, transcribed, and coded by 2 independent coders using thematic analysis, resolving discrepancies by consensus. Interviews continued until data saturation was reached.

RESULTS

We interviewed 40 caregivers who were predominantly Black (88%) mothers (90%), with 53% and 83% currently using WIC and SNAP, respectively. We identified 4 themes related to participation barriers: (1) limited product variety available through WIC, (2) inconvenience and stigma associated with purchasing WIC products, (3) SNAP income-based eligibility criteria, and (4) burdensome SNAP enrollment and recertification processes. We identified 3 themes related to suggestions for improvement: (a) decreasing stigma associated with participation, (b) allowing online or phone-based enrollment, and (c) improving coordination with health care systems.

CONCLUSIONS

WIC and SNAP beneficiaries identified several modifiable barriers to enrollment and benefits redemption. Pediatric providers should advocate for programmatic improvements that make it easier for families to access and redeem benefits and should consider implementing innovative cross-sector interventions like medical–financial partnerships, direct WIC and SNAP referrals, and data sharing with government assistance offices.

Authors: Cardozo Fernando Alves Cantini , Petter Carlos Otávio , Campos Higor José Silva
Published: October 2024

This work aims to present and discuss a conceptual project of mining tailings dam. Therefore, specific topics on tailings dams are visited and the characterization of materials constituting such structure is reviewed in the literature. Based on parameters available in the literature, a hypothetical dam was schematized and its stability was assessed via computational analysis (limit equilibrium and finite element flow analysis). Assessing eventual design changes (additional dam heightening) and hypothetical situations (collapses in the internal drainage), it is concluded that the schematic conceptual design presents itself viable and stable given the proposed geometry and the properties of materials considered. The importance of the internal drainage system for the dam´s stability was also identified.

Authors: Alvarez-Rivera José Abisenas , Castañón-Nájera Guillermo
Published: October 2024

The use of refined used lubricating oils (RULO) is an opportunity for use for the industrial sector, improving the environment. The objective of the research was to evaluate different RULO/diesel mixtures from the AT80 and AT40C1 treatments. The experiment consisted of applying different proportions of RULO, forming five different mixtures between ALUR/diesel. The mixes were 85/15, 70/30, 55/45, 40/60 and 30/70. The results showed that the best mixtures were M4 and M5 of the AT80 treatment, with average density of 0.80 g/cm3, viscosity of 5.83 cP, electrical stability of 1694.33 V, flash point of 95°C and 96.67% oil. With these results, a new alternative and use is created, reducing diesel and economic costs for the oil industry that prepares oil-based drilling fluids.

Authors: Criollo Jenifer , Rodríguez José R. , Pedroza Kelly J. , Sánchez Juan M.
Published: October 2024

In this study, drying techniques including lyophilization, forced convection, marquee with polyshade, and refractive window were evaluated in the post-harvest residue of Nufar variety basil (Ocimum basilicum L.) in the department of Tolima, Colombia. The physicochemical and bromatological analysis showed that lyophilization and forced convection better maintained the organoleptic properties of dry basil, while the marquee with polyshade technique did not affect the phenolic content and antioxidant capacity. The refractive window technique showed higher rehydration capacity but lower essential oil content. In the sensory evaluation, the infusions of dried leaves in the marquee with polyshade method were highly accepted. The results suggest that drying by forced convection and marquee with polyshade are effective methods to preserve the quality of dried basil, presenting a viable alternative for the use of post-harvest residue and improving the useful life of the product, benefitting local producers by increased employability and added value.
Higher Risk Hospital Based Maxillofacial Sedation for ASA 3 and ASA 4 Patients using Propofol Based Target Controlled Infusions
Authors: DG Wells , A Bridgeman , R Barrowman
Published: October 2024

There is a paucity of information regarding the administration of Target Controlled Infusion (TCI) sedation to American Society of Anesthesiology (ASA) class 3 and 4 patients for maxillofacial procedures. We report a selection of ASA 3 and ASA 4 patients who recently underwent dental extractions by maxillofacial surgeons and were managed under TCI propofol sedation in mainstream hospital settings. The utilisation of effective TCI propofol sedation, accompanied by an ultra short-acting narcotic (either alfentanil or remifentanil) given immediately prior to the administration of local anaesthetic (LA) by the surgeon, permits the avoidance of higher risk general anesthesia and its associated complications within this more infirm patient group. Effective use of TCI sedation in ASA 3 and ASA 4 maxillofacial patients requires the provision of skills routinely employed for sedation in healthy patients, with the appropriate dosage modifications necessitated by age and associated patient co-morbidities. Properly administered in a hospital setting, TCI sedation with propofol accompanied with an ultra-short acting narcotic is safe and effective.

Authors: Sevinç Mehmet Sedat , Karaca İsmail
Published: October 2024

This study aimed to investigate the effects of local Beauveria bassiana (Balsamo) Vuillemin and Cordyceps fumosorosea (Wize) (Hypocreales: Cordycipitaceae) isolates on Ceratitis capitata (Wiedemann, 1824) (Diptera: Tephritidae) prepupae, during 2020 and 2021 in the Mediterranean Region of Türkiye. In petri dishes, mortality rates varied with doses: for LD.2016 (B. bassiana), between 30 and 60%, for M6-4 (B. bassiana), 30-46%, of IFR (C. fumosorosea), 65-100%. Additionally, differences were detected between the prepupa and pupa periods of the larvae depending on the isolate. In sterile soil studies, the IFR caused mortality rates of 53-93%, while those for the LD.2016 isolate were 20-55%., depending on the doses. In conidial survival studies, the IFR caused mortality rates of 70-93% at 0 months and 44-60% in the 12th month. The LD.2016 mortality was among 37-55% at 0 months, while mortality rates decreased to 2% in the 12th month. The reproductive capacity of adult individuals that emerged alive after infection was negatively affected depending on time and fungal isolate. In semi-controlled field conditions, the IFR isolate had mortality rates varied between 40 and 65%, and LD.2016 mortality rates varied between 34 and 62%, depending on doses. It was observed that the fungi used in the study had potential in biological control of C. capitata.
Prodigiosin, a promising biocontrol agent against Thaumetopoea wilkinsoni (Tams, 1926) (Lepidoptera: Notodontidae)
Authors: Koç Muhammed , Bekircan Eski Duygu , Demir İsmail , Eski Ardahan
Published: October 2024

Serratia marcescens Bizio (Enterobacteriaceae: Serratia) is an entomopathogenic bacterium that produces hydrolytic enzymes and toxins. It also produces a pigment with various biological properties called prodigiosin. The study was conducted at Bilecik Seyh Edebali University in 2023. In this study, the effects of medium, incubation temperature and time on the process of prodigiosin production by S. marcescens strain Se9 and the extraction efficiency of different solvents were optimized for the first time using the orthogonal Taguchi array design. The optimal yield of pigment was achieved by methanol extraction from bacteria grown in tyriptic soy broth medium at 30ºC for 96 hours. The yield of prodigiosin pigment was 83.4±1.7 mg/L in the validation experiment conducted under the optimum conditions determined. The insecticidal potential of pigment against the larvae of Thaumetopoea wilkinsoni (Tams, 1926) (Lepidoptera, Notodontidae) was demonstrated for the first time. While the mortality rate in larvae exposed to 1000 ppm of the pigment was only 40%, it was observed that doubling the applied concentration led to a significant increase in larval mortality, reaching 91%. The LC50 value of the pigment for the fourth larval stage of T. wilkinsoni was determined to be 1192 ppm. The study showed that the pigment prodigiosin may be a promising biocontrol agent for the control of T. wilkinsoni.

Authors:   Kyrgyz State Medical Academy named after I.K. Ahunbaev, Musaeva Khalida , Osmonaliev Kudaibergen ,   International University Ala-Too
Published: October 2024

Effective and rapid diagnosis of stroke, as well as verification of factors determining its outcome, are of crucial importance, and largely predetermine the prognosis of the disease. We studied neuroimaging features in patients with acute ischemic stroke associated with fatal outcome. The study design was a cohort, retrospective, comparative, analytical study, which included the analysis of medical records of 100 patients over 18 years of age with the diagnosis of ischemic stroke. As a result, in patients who were included in the main study group (those who died from ischemic stroke or its complications), hospital mortality was associated with initial severity of the condition due to soporotic consciousness, short hospital stay, unstable hemodynamics, and respiratory failure, which was the reason for the need for ventilator use. The neuroimaging picture in the deceased patients was characterized by signs of increasing cerebral edema with dislocation phenomena.More aggressive control of vascular risk factors, including hypertension, diabetes and hyperlipidemia at the prehospital level is preventive not only of stroke itself, but also of its complicated forms, which ultimately affects the incidence of ischemic stroke and mortality from it.
RISK FACTORS AND PREDICTORS OF THE DEVELOPMENT OF DEEP VEIN THROMBOSIS OF EXTREMITIES IN PATIENTS AFTER STROKE (LITERATURE REVIEW)
Authors:   Kyrgyz State Medical Academy named after I.K. Ahunbaev, Torokulova Karlygach
Published: October 2024

Currently there is no reliable evaluation system for predicting deep vein thrombosis (DVT) in the hospital after ischemic and even more – hemorrhagic stroke. Objective: to review current literature data on the verification of risk factors for the development of DVT in stroke patients and aggressive and early screening strategies in the early post-stroke period. Three fundamental factors underlie the development of DVT: damage to the venous wall, the tendency of blood to hypercoagulation and slow blood flow. Most of the factors that are more or less associated with the development of thromboembolic events revolve around these 3 elements. Typical factors were older age, female gender, changes in the levels of clinical and laboratory variables such as D-dimer or scores on the Berg equilibrium scale. An effective model of risk stratification for DVT at the hospital level after a stroke would be useful for identifying high-risk patients and for implementing individual preventive strategies, therefore further population studies are needed, including in Kyrgyzstan.

Published: October 2024

Objectives: To develop an Integrated validated Physiotherapy Treatment Protocol for Desk Job personnel along with an assessment of its effectiveness. Methods: The research was conducted utilizing a mixed-method methodology. Interviews with thirty computer professionals (having more than five years of experience) and a thorough in-depth literature research were conducted to identify various symptoms which are commonly seen among computer professionals. Search engines such as Ovid MEDLINE, Cochrane Library, Pubmed, and EBSCO CINAHL were used with terms such as Neck Problems in Computer Professionals(cs), Treatment Techniques used in Cervical Spondylitis, and Motor or Sensory issues in Computer Professionals. The treatment protocol was created with the help of identified symptoms and validated using the Delphi technique. After the protocol was developed, a randomized control trial was conducted with thirty samples in each group. A developed and validated regimen was provided to the participants. Findings: Item level CVI ranges from 0.79 to 1. The Kappa results demonstrated the protocol's strong content validity, which ranged from 0.79 to 1. In comparison to day 1, there was a decline in both groups' scores of NDI and NPRS on day 30, and there was an even more noticeable decrease on day 60. The experimental group showed a much greater reduction in neck pain and disability when compared to the control group. Novelty: The study has focussed on a new category of occupational health issues, namely computer-related health issues, for which there is no established set of Physiotherapy Protocol that can either prevent or treat the issues.

Published: October 2024

Objectives: Network Intrusion Detection System (NIDS) plays an important role in finding and preventing cyber-attacks, which helps to improve the entire security posture of an organization’s network infrastructure. The development of Deep Learning (DL) techniques possess the ability of IDS to detect attacks without delay and protects from intrusions even in real-time environment. Methods: The present study proposes an improved IDS framework called Enhanced Gated Recurrent Unit Hyper-Model combined Attention Bidirectional Long-Short Term Memory (EGHAB) approach, to effectively address the detection of attacks with maximum accuracy and minimal error rate. The proposed model is enhanced by using methods like numericalization and normalisation for pre-processing the input data, Genetic Algorithm (GA) for extracting intricate features from the input data, and the EGHAB classifier, which works on the principles of both Gated Recurrent Unit (GRU) and Bidirectional Long-Short Term Memory (BiLSTM) models along with attention mechanism. Findings: The EGHAB model efficiently learns the abnormal behaviour of network and classified the attack and non-attack data using the publicly available NSL-KDD dataset and a generated real time data set, scapy. And it achieved 99.94% accuracy over NSL KDD dataset during multiclass classification and 93.3% on real time data set with reduced Error rate. Additionally, to examine the efficacy, the proposed approach is compared with other existing methods and proved its improved performance. Novelty: A combined ensemble classifier with GRU, BiLSTM and attention mechanism is designed to predict the attacks in earlier stage rather than due over. The model achieved better accuracy and reduced false assumption using anomaly prediction mechanism.

Authors: Zhang Ying , Wang Xi , Xiao Feng , Liu Hui , Zhu Hequan , Liu Qing , not provided Xin
Published: October 2024

ABSTRACT Background: Chronic postsurgical pain is common, affecting more than 30% of the world’s population, with patients undergoing open-heart surgery being a high-risk group for chronic postsurgical pain. Methods:Weretrospectively analyzed the clinical data of 830 patients who underwent open-heart surgery, screened the key variables of chronic postsurgical pain using multifactorial logistic regression, and constructed and compared eight machine-learning models. Finally, the models were interpreted using the SHapley Additive exPlanations package. Results: Nine key characteristics were screened: age, diabetes, coronary artery disease, length of hospitalization, history of preoperative pain, number of pain medications required (>3), postoperative incision infection, length of surgery, and use of remifentanil. Among the eight algorithms, the logistic regression algorithm exhibited the best performance. Following reconstruction with the logistic regression algorithm, the areas under the curve for the training and validation sets were 0.846 and 0.836, respectively. The algorithm also demonstrated strong performance on the test set (area under the curve=0.825, accuracy=76.8%, sensitivity=79.2%, F1 score=0.736). The validation set’s area under the curve was within 10% of that of the test set, indicating a well-fitted model. Conclusions: A machine-learning model, utilizing accessible clinical data, can accurately predict chronic postsurgical pain in open-heart surgery patients at an early stage, which helps to accurately identify and improve their prognosis.

A fresh look at a randomized massively parallel graph coloring algorithm
Authors: Gabrovšek Boštjan , Žerovnik Janez
Published: October 2024

Petford and Welsh introduced a sequential heuristic algorithm to provide an approximate solution to the NP-hard graph coloring problem. The algorithm is based on the antivoter model and mimics the behavior of a physical process based on a multi-particle system of statistical mechanics. It was later shown that the algorithm can be implemented in a massively parallel model of computation. The increase in computational processing power in recent years allows us to perform an extensive analysis of the algorithms on a larger scale, leading to the possibility of a more comprehensive understanding of the behavior of the algorithm, including the phase transition phenomena.
Multi server queuing model with dynamic power shifting and performance efficiency factor
Authors: V Sreelatha , Mamatha Elliriki , Reddy Chandra S , Anand S Krishna
Published: October 2024

The need for high performance models in the queuing systems; availability in the fields of computing and communication systems and logistics management poses extensive challenges in design and development of the appropriate modeling. In this work, we propose a robust probabilistic model to mitigate these problems by appropriately choosing a multi-server queuing system with dynamic service facility. The arrival substances, such as packets or jobs or customers or consumers, follow a Poisson arrival process and these arrivals enter a queuing system according to FIFO discipline. The system designed in the system is armed with a fixed number of service stations, in which some servers are capable of allocating additional service capacity by adjusting dynamically. When a customer arrives at the system, if a free server is available, it is immediately served by one of the free processors; if no server is free, that is all are busy, the arrived job is accommodated in the queue and waits for service in the system. In this paper, we proposed a stochastic model to handle peak loads efficiently, boosting service capacity during burst arrivals. Numerical results presented in this paper are generated by the spectral expansion method to demonstrate the model’s performance, offering insights into its efficiency and accuracy. Furthermore, we derived some important special cases of speedup factor, which provide the mathematical estimation of system performance in terms of computation and communication times.

The Minimum Dominating Sets (MDS) problem is pivotal across diverse fields like social networks and ad hoc wireless networks, representing a significant NP-complete challenge in graph theory. To tackle this, we propose a novel hybrid cuckoo search approach. While cuckoo search is renowned for its wide search space exploration, we enhance it with intensification methods and genetic crossover operators for improved performance. Comprehensive experimental evaluations against state-of-the-art techniques validate our approach's effectiveness.

The longest induced (or chordless) cycle problem is a graph problem classified as NP-complete and involves the task of determining the largest possible subset of vertices within a graph in such a way that the induced subgraph forms a cycle. Within this paper, we present three integer linear programs specifically formulated to yield optimal solutions for this problem. The branch-and-cut algorithm has been used for two models that cannot be directly solved by any MILP solver. To demonstrate the computational efficiency of these methods, we utilize them on a range of real-world graphs as well as random graphs. Additionally, we conduct a comparative analysis against approaches previously proposed in the literature.

Estimating Real Seismicity Rates from Nonhomogeneously Recorded Earthquake Catalogs
Authors: Ogata Yosihiko
Published: October 2024

Accurate estimation of seismic activity using epidemic-type aftershock sequence (ETAS) models for small earthquakes is complicated by the incompleteness of the aftershock catalog immediately following frequent large earthquakes. For example, in conventional aftershock analysis using the ETAS model, the earthquakes immediately following the mainshock, including the mainshock, are used only as a history, and the estimate is based on data for subsequent segments above the lower magnitude limit where detection completeness can be guaranteed. However, the high activity in the missing interval itself contains important clues to the physical structure associated with the immediate aftershocks. In this article, I consider all detected seismic data, even if incomplete. I try to estimate the detection probability of each earthquake in the catalog and show how to estimate the real underlying activity of the ETAS and nonstationary ETAS models.
Rotaphone-D, A New Model of Six-Degree-of-Freedom Seismic Sensor: Description and Performance
Authors: Brokešová Johana , Málek Jiří
Published: October 2024

A new model of the Rotaphone-D short-period seismic sensor with six degrees of freedom is introduced. The basis of the instrument is horizontal and vertical geophones in a special paired arrangement. The instrument is designed for simultaneous and collocated measurements of rotational and translational components of ground motion. The basic principle of measurement is briefly described. Careful calibration is necessary for this type of measurement, which has two parts: a preliminary calibration based on laboratory measurements of the characteristics of the individual geophones, and a subsequent in situ calibration, which takes into account the actual physical conditions during field measurements and is performed during the processing of the measured data. The effect of the calibration is demonstrated by specific laboratory tests. The laboratory tests have confirmed the correct functioning of the instrument. The frequency range of Rotaphone-D is from 2 to 80 Hz and is therefore optimal for monitoring local seismicity. The instrument was subsequently used in field measurements during two several-month measurement campaigns in California, United States. Examples of six-component records from two sites—The Geysers and Long Valley Caldera—are presented and briefly interpreted from a seismological perspective. Basic instrument parameters are given. The instrument is lightweight, portable, easy to install, and offers several interesting applications, which are briefly discussed. Six-component measurements (translational and rotational) have become a powerful tool, especially in volcanic seismology and in monitoring induced seismicity.
Simulating the Impact of Fuel Prices Rising and Direct Cash Assistance Compensation (BLT BBM) on Poverty in Indonesia
Authors: Romadhon Ariful , Adji Ardi
Published: October 2024

Crude oil prices have become volatile as geopolitical conflicts that occur in oil-exporting countries make the Indonesian government have to increase fuel prices and plan to provide cash transfers as compensation. This study analyzes the impact of fuel price rising and the direct cash assistance compensation program/Bantuan Langsung Tunai (BLT BBM) on poverty using micro data simulation. Poverty simulation is generated by modifying the poverty line (GK) and expenditure by utilizing leading indicators such as commodities inflation, household consumption expenditure growth, and population growth. The simulation results show that the presence of compensation can reduce the poverty rate compared to the absence of compensation. Without compensation, the poverty rate in September 2022 is predicted to be 10.36 percent (0.82 percent higher than in March 2022), while under the government's scheme where compensation is given to households receiving the Family Hope Program (PKH)/Non-Cash Food Assistance (BPNT), poverty is predicted to be 9.56 percent (0.02 percent higher than in March 2022). Exclusion error in the program of 55.35 percent in the lowest decile is an obstacle in poverty alleviation. Improvement and updating of the database of program recipients is needed so that the program can be more targeted to reach the poor.
Application of tests for contagion in point processes to measles, Chlamydia, Lyme disease, and suicide
Authors: Schoenberg Frederic
Published: October 2024

A recently proposed likelihood-ratio test for identifying causal triggering in point process data is applied to a variety of case counts of diseases of varying infectiousness. The test, suggested by McGovern et al. (2023), involves comparing the likelihood of a fitted Hawkes model to that of a fitted Poisson cluster model, and was shown using simulations to be powerful at discriminating between a process with causal triggering and a process where the clustering is merely due to spatial-temporal inhomogeneity. Here, the test is applied to data on measles, Chlamydia, and Lyme disease in the United States, to see if the test can discern between diseases that are highly contagious, moderately contagious, and not directly contagious from human to human. Measles is a highly contagious disease that spreads rapidly through populations, so it can potentially be modeled accurately using a Hawkes model. Chlamydia is a sexually transmitted disease that is not as highly contagious as measles since the level of contact needed for exposure is much higher than for measles. Lyme disease is non-contagious from human to human but cases tend to be highly clustered, as the disease is primarily spread through ticks, and this exposure is much more likely to happen during warmer weather. Further, the test is applied to data on adolescent suicides in the United States, in order to investigate the hypothesis that such suicides are an epidemic spread by social contagion. The results show that the test is able to measure the degree of contagion of a disease, and the results suggest that there is indeed a small but statistically significant element of contagion to youth suicides.
Quality Inpainting and Region Filling Using a Complete-Composite Patch Sampling Scheme (CCPSS) Based on Statistical Estimation

Published: October 2024

Research in the field of Inpainting and Region filling has nowadays gained immense momentum to account for historical and ancient mural conservation and the technological advancements as regards the need for image processing applications. This work proposes a complete Composite Patch Sampling Scheme (CCPSS) incorporating four refinements over Criminisi and other state-of-the-art techniques. The earlier Criminisi patch matching approach is supported by adding alien patches generated from independent color components of the existing known or valid patches. The dependency of confidence and data terms used in the priority function had been removed by selecting unknown pixels based on their neighborhood unknowns. The proceeding estimated unknown pixel patches are considered in estimating successive invalid pixel patches. Lastly, the highest similar or consistent known patch concerning an unknown patch is not finalized but retained until all the unknown patches are estimated. The true value of any unknown pixel is computed using the mean and median of all retained values. The inpainting, region filling, and reconstruction quality of the CCPSS scheme is superior in terms of visual perception when tested over high-resolution texture-structure images at the cost of computational overhead.

Published: October 2024

Investigating digital public service innovation in Indonesia is essential for improving practical applications and developing a unified theoretical understanding of digital innovation in the public sector. This research is particularly relevant in the global conversation about digital progress in both developed and developing nations. Indonesia's situation is uniquely instructive for several reasons: At the macro level, despite ambitions to become a digital economy, Indonesia faces the challenge of low internet penetration. At the meso level, governmental goals to digitize public services are hindered by unclear integration strategies within bureaucratic systems, revealing a gap between policy and execution. At the micro level, the need for digital literacy in the public sector is evident, but Indonesian civil servants currently fall short of the required standards, highlighting an urgent need for skill development. This study is crucial not only for enhancing local practices but also for contributing to a broader understanding of digital transformation in the public sector across different stages of national development. The research methodically reviews and maps digital public service innovation within the Indonesian context, employing a best practices approach and using the PRISMA flowchart for content analysis. Data was sourced from the Kemenpan-RB database on the Public Service Innovation Competition (KIPP) from 2014-2022. This database is a primary source of information on Indonesian Public Service Innovation and is noted for its reliability. The findings reveal a diverse range of strategies that balance interactivity with information delivery, internal efficiency with external engagement, and collaboration with self-reliance, providing a comprehensive view of the current state and potential future of digital public service innovation in Indonesia.
