Published: August 2024

Kelurahan Bangetayu Wetan di bawah pembinaan Puskesmas Bangetayu, dalam kurun waktu 1 tahun terdapat Balita dengan stunting sebanyak 85 kasus. Puskesmas sudah melakukan upaya pencegahan stunting dengan membuat program pembangunan status gizi, memberikan informasi tentang stunting kepada masyarakat, melakukan kunjungan ke rumah dan memberikan makanan tambahan untuk anak yang mengalami stunting. Namun belum ada kelompok khusus yang dibentuk untuk konsentrasi dan fokus menangani masalah stunting, sehingga kejadian stunting di Puskesmas Bangetayu masih cukup tinggi. Solusi yang ditawarkan yaitu Pemberdayaan Kelompok Ibu Sadar Gizi (BuDarZi) melalui metode peer group. Salah satu fungsi Kelompok Ibu Sadar Gizi (BuDarZi) adalah sebagai wadah pemberdayaan masyarakat khususnya para ibu untuk dapat bertukar informasi dan pengetahuan untuk dapat meningkatkan derajat kesehatan anak dan keluarga melalui pemenuhan asupan gizi yang sesuai. Pembentukan kelompok BuDarZi diikuti sebanyak 25 ibu yang memiliki bayi dan Balita. Hasil kegiatan PKM menunjukkan terjadinya peningkatan pengetahuan ibu tentang gizi, pengetahuan ibu tentang tumbuh kembang anak dan keterampilan ibu membuat MPASI sebalum dan sesudah pembentukan Kelompok BuDarzi. Kesimpulan, pembentukan kelompok BuDarZi dinilai efektif sebagai upaya pencegahan stunting yang terjadi di masyarakat.Bangetayu Wetan Subdistrict under the guidance of the Bangetayu Community Health Center, within a period of 1 year there were 85 cases of stunting in toddlers. The Community Health Center has made efforts to prevent stunting by creating nutritional status development programs, providing information about stunting to the community, conducting home visits and providing additional food to children who are stunted. However, there has not been a special group formed to concentrate and focus on dealing with the problem of stunting, so the incidence of stunting at the Bangetayu Community Health Center is still quite high. The solution offered is the Empowerment of the Nutrition Aware Mothers Group (BuDarZi) through the peergroup method. One of the functions of the Nutrition Aware Mothers Group (BuDarZi) is as a forum for community empowerment, especially mothers, to be able to exchange information and knowledge in order to improve the health status of children and families through fulfilling appropriate nutritional intake. The formation of the BuDarZi group was attended by 25 mothers who had babies and toddlers. The results of PKM activities show an increase in mothers' knowledge about nutrition, mothers' knowledge about children's growth and development and mothers' skills in making MPASI before and after the formation of the BuDarzi Group. In conclusion, the formation of the BuDarZi group is considered effective as an effort to prevent stunting that occurs in the community.

Published: August 2024

The purpose of this research is to examine the form of legal protection in PT Yotta's Investment Model Business Agreement. The research method used is the normative-empirical method, which combines elements of normative law with empirical data. The results show that legal protection for the parties in PT Yotta's investment business model agreement is provided in preventive and repressive forms. Preventive protection is reflected in the contract provisions that regulate the rights and obligations of the parties, providing a strong foundation for the maintenance of justice and security. In addition, repressive protection is facilitated by the dispute resolution procedures set out in the agreement, which include the stages of deliberation to reach consensus and the arbitration process. Based on this research, the need for special attention to law enforcement in dealing with cases based on Sharia economic law or Islamic law is highlighted. This is due to the dominance of legal sources from the Civil Code in the context of this still developing law. It is therefore necessary to improve the understanding and skills of law enforcement agencies in dealing with cases involving the principles of Sharia economic law or Islamic law. Therefore, legal protection in the investment business model for the needs of Generation Z provides a solid framework for security and justice for all parties involved. By considering the preventive and repressive aspects, this research provides insightful insights into the legal protection of investment business models.
Exhibitionism and Law Enforcement: Criminal Law and Islamic Criminal Law Perspectives
Authors: Nafis Str Raihan Hadi , Azizah Noor
Published: August 2024

Law enforcement against exhibitionists is crucial in maintaining public order and morality. This study examines law enforcement against exhibitionists based on criminal law and Islamic criminal law. The research method used is normative legal research with a statute and conceptual approach. The statute approach is employed to review existing laws and regulations. In contrast, the conceptual approach explores the principles of Islamic criminal law related to law enforcement against exhibitionism. The results of this study show that in the context of general criminal law, the Indonesian Penal Code (KUHP) regulates articles that can be applied to exhibitionists. Criminal sanctions stipulated in Articles 281 and 282 of the Penal Code include imprisonment and fines for those who distribute, create, or store obscene images, including those involving exhibitionism. Article 335 of the Penal Code also regulates indecent acts in public, which can include exhibitionism. According to Islamic criminal law, the form of punishment for exhibitionist behavior is jarimah ta'zir. Among the Syafi'iyah and Hanabillah scholars, it is argued that the maximum punishment is ten lashes. Meanwhile, according to the Malikiyyah scholars, the punishment of lashes may exceed this limit as long as it serves a beneficial purpose. This study concludes that law enforcement against exhibitionism requires integrating general and Islamic criminal law to create a balanced legal framework that aligns with societal values. Additionally, the importance of public awareness of the social impact of exhibitionism and participation in law enforcement is emphasized

Ignition Delay Period Prediction for Compression Ignition Engines Fueled with Ethanol/Diesel Blends
Authors: Ghareeb Hemin Othman , Anjal Hassan Abad Al-Wahab
Published: August 2024

A key characteristic of diesel engines is predicting the ignition delay period. This work predicts the ignition delay in diesel engines using combinations of ethanol/diesel fuel blend and pure diesel as fuel replacements. It provides an empirical formula for predicting delay periods.  A growing interest in alternative fuel blends, representing a substantial shift from the use of traditional diesel fuel, is reported. Modern study is focused on examining these combinations and how they might affect the dynamics of combustion in diesel engines. Experiments were carried out utilizing five different ethanol/diesel fuel blends, including pure diesel, with ethanol percentages varying from 5% to 20% in 5% quantities. Tests were conducted at a constant engine speed of 1,500 rpm, with various compression ratios of 16, 17, and 18, with torque levels ranging from 0 to 21 N.m. In this study, general formulas for predicting ignition delay are constructed numerically. There was a greater consistency between the experimental outcomes and the expected ignition delay. The findings indicated that the E20 combined fuel continuously exhibited the least igniting delay period across all compression ratio variables. The findings demonstrated that the ignition delay period starts to shorten with increased cetane number, ignition pressure, temperature, and equivalency ratio. A shorter period of ignition delay is the outcome of higher compression ratios. The predictive model created here is a ground-breaking addition to the industry, offering a solid foundation for assessing the efficiency and emissions properties of different ethanol/diesel blends.

Published: August 2024

This article demonstrates how different cooling rates and precipitation hardening affected the mechanical properties of AA2024. Three impact test samples were chosen. Solution heat treatment was conducted at 500 °C for 2 hrs., followed by quenching in three different quenching media (Sunflower Oil, Sesame Oil, and Corn Oil). As a result, the Sunflower Oil showed the lowest shock absorption rate; hence, it was chosen as the quenching medium for this study. Consequently, all samples of tensile, hardness, and impact tests were solution heat treated at 500 °C for 2 hours, then quenched in Sunflower Oil to room temperature and artificially aged at temperatures of 180°C for 1,2,4 hour, 195°C for 1, 2, 4 hour, and 210°C for 1,2,4 hour. Considerable improvements in strength and hardness were observed while decreasing the ductility Due to the production of finely dispersed grains. Precipitation hardening at 180°C for 1 hour was the overall optimum achievement, which enhanced the UTS by 28.7% to 579 MPa, compared to the as-received sample with UTS 450 MPa. While annealing has reduced the UTS by 32.7% to 303 MPa.

Published: August 2024

The Post-project evaluation in highway construction is crucial but underdeveloped in infrastructure management, especially for Iraqi road project authorities. This comprehensive study combines insights from global schemes in England, Scotland, France, Australia, Norway, and New Zealand to develop a strong post-evaluation framework. This study used criteria from six international schemes, a thematic analysis framework, and open interviews with experts to identify and improve the final list of criteria that could be used in the evaluation process. Five criteria were identified as the final result, which are efficiency (cost, time, and quality), traffic analysis (volume, travel time, and impact), safety (accidents and security), sustainability, and impact (economic and social). Then, to develop a multiple regression model for the success of a project, criterion weights were derived through the utilization of the Inner Product Vector (IPV). This study emphasizes the need for a comprehensive post-evaluation framework, especially in complex highway construction. A milestone is reached when international standards and careful variable extraction are combined. Based on empirical data and expert judgment, the mathematical model simplifies assessment and predicts project success, giving stakeholders a systematic, impartial, and comprehensive evaluation tool.
Numerical Study of Evaporative Cooling System Performance Using Well Water Driven by PV Panels on Thermal Comfort for Relief Tents
Authors: Rashid May Abdulazeez , Aljubury Issam M.Ali
Published: August 2024

When multitudes of people need to be evacuated from their homes for various reasons, including natural catastrophes and armed conflicts, time and money are of the essence. Therefore, emergency relief tents are considered the most effective option for this situation. However, the indoor environment of these tent types might be thermally uncomfortable, particularly on hot or extremely cold days. Different techniques were used to overcome this problem including evaporative cooling systems. The present study aims to use a numerical approach to assess the impact of utilizing a two-stage indirect/direct evaporative cooling system on enhancing the interior thermal comfort conditions of the relief tent. The numerical part was done by utilizing software that was written in Fortran language to simulate the case under various parameters, including changing the cellulose pad thickness and the volumetric water flow rates in the second heat exchanger of the indirect cooling stage. The selection of boundary conditions that were applied in numerical analysis was based on experimental data collected over specified days during the summer of 2022, in particular from July 15th to September 15th. According to the findings, having two heat exchangers in the indirect cooling stage of the cooling system helps keep the tent model at a comfortable temperature because of the exceptional performance of the proposed cooling system in lowering both dry and wet bulb air temperatures before entering the direct evaporative cooling stage. In addition, it was found that the indoor temperature drop increased by about 19% when increasing the thickness of the cellulose pad and raising the water flow rate in the second heat exchanger of the indirect cooling stage.

Authors: Abd AL_Kadhim Mjali Maryam , Gzar Hatem A.
Published: August 2024

As a viable solution for the treatment and recycling of sewage from residential areas, this research presents membrane bioreactors (MBRs) systems, both immersed and side-stream. These systems are offered as viable options. This study's objective is to analyse the overall performance of each membrane bioreactor in terms of its capacity to meet water reuse requirements. This will be accomplished with the assistance of water quality indices such as total suspended solids (TSS), biological oxygen demand (BOD), and chemical oxygen demand (COD). It is obvious from the data that the MBR system is capable of producing permeate water of a high quality and that the MBR technology is efficient in reducing total suspended solids (TSS). COD and BOD rejection rates in the submerged MBR were, on average, 92.76% and 94.46%, respectively. This was the case. Comparatively, the percentages of COD and BOD that were rejected in the side-stream MBR were 87.54 percent and 88.98 percent, respectively. It has been discovered through the examination of COD and BOD that the removal of the submerged MBR system is preferable to the removal of the side-stream MBR system.
Economic Analysis for Performance of Photovoltaic-Direct-Powered Solar Domestic Hot Water Systems Using Experimental Evaluation in Iraq
Authors: Atta Baneen , Ali A. F. Al-Hamadani  , Emad Jaleel Mahdi
Published: August 2024

Photovoltaic (PV) systems can be used in a wide range of applications because of a significant drop in cost over the last ten years for PV modules. Because PV solar panels are low-cost and have a simple design that just requires sunshine to work, they can be used to power loads that are directly linked to PV panels. Because of this, it is a more alluring option for applications involving water heating.
In this work, experimental evaluation has been done for photovoltaic-direct-powered solar domestic hot water systems on 3/Jan./2024 a clear, sunny day. When evaluating performance, the value of power generated by PV panels is crucial. As solar radiation rises, its value rises as well. The PV heater tank's inside water temperature reached a maximum of 83.50 °C. A family of three members used 131 liters of water at a flow rate of 2 L/m. The maximum power delivered to the heating element was 1188 W, and the maximum power generated by PV panels was 1240 W. Based on the specifications of the 1500W heating element utilized, about 312W of electricity is lost during operation. Calculations revealed that the system's electrical efficiency was 22.3%. The system required 8.6 years of payback time to recoup its initial expenditure. Based on these results, it is advised to utilize a direct- connected photovoltaic water heater system (DPVWH) in cold weather because of its ease of use and efficiency, as it is a technology that operates during daylight hours.

Published: August 2024

Colombia currently faces the challenge of integrating into civil life two large segments of population: over fourteen thousand FARC-EP ex-combatants from peace agreements after five decades of conflict, and nearly two million Venezuelan migrants. Successful integration heavily depends on fostering public acceptance of these groups. Prior research by Halperin et al. (2013) and Hurtado-Parrado et al. (2019) demonstrated the effectiveness of reappraisal training, a brief emotion-regulation intervention, in reducing negative emotions (e.g., anger, irritability, fear) and aggressive attitudes (e.g., support for war or opposition to the peace process), while increasing conciliatory attitudes (e.g., support for humanitarian aid). The present study extended those findings via testing reappraisal training to promote positive attitudes towards FARC-EP ex-combatants (Experiment 1) and Venezuelan migrants (Experiment 2). In both experiments, reappraisal training reduced negative emotions and support for aggressive statements, while increasing support for conciliatory statements. In addition, negative emotions mediated the effect of reappraisal on both aggressive and conciliatory statements. Lastly, reappraisal training increased participants’ willingness to donate, a measure of prosocial behavior tested for the first time in this line of research. These findings add to the evidence of the effectiveness and generalizability of reappraisal training across a wider range of social targets and prosocial behaviors, and its potential to inform public policy and promote larger-scale social integration efforts.
Walk the Talk: The Effects of Apology and Reparation After Acts of Prejudice
Authors: Szanton Elizabeth Cannon , Kodipady Aditi , Onyeador Ivuoma Ngozi , Young Liane
Published: August 2024

In an era of abundant high-profile apologies, many of which are perceived to be cheap and insincere, it is crucial to understand what constitutes a meaningful response from a high-status perpetrator. In each of three studies using a 2 (apology: present, absent) x 2 (reparation: present, absent) within-subjects design, we presented participants (Ntotal = 297) with 16 vignettes describing acts of prejudice and perpetrators’ responses. The presence of an apology and of reparation each independently predicted more positive perceptions of the perpetrator’s response. Reparation exerted a stronger effect than apology on overall ratings (Study 1) and on ratings of the response’s impact (Studies 2 and 3). Additionally, responses were perceived more positively overall in the context of close relationships (Study 3). We suggest that while apology and reparation are each key to an effective response, reparation plays an especially important role in predicting positive reception to a response to prejudicial harm.

Published: August 2024

A fertirrigação é uma das alternativas para o parcelamento da adubação em cultivos agrícolas, evitando perdas por lixiviação ou volatilização dos adubos, porém o seu uso excessivo e inadequado pode levar a salinização de solos, principalmente em casas de vegetação, pois o excesso de fertilizantes eleva a condutividade elétrica na solução do solo,  causando redução na produtividade das culturas. No presente texto, foram revisados trabalhos que direta ou indiretamente, abordaram o efeito da fertirrigação excessiva e sua contribuição ao processo de salinização de solos sob ambiente protegido, que apresentaram informações sobre a tolerância das culturas à salinização e seu manejo conjunto com a fertirrigação. Palavra-chave: condutividade elétrica; solução do solo, fertilizantes.   FERTIGATION AND SOIL SALINIZATION PROCESS IN GREENHOUSE ABSTRACT Fertigation is one of the options to split fertilizer application in crops, preventing fertilizers losses by leaching or volatilization, but its excessive and inappropriate use can lead soil salinization in greenhouses, because the fertilizer excess increases the electrical conductivity in soil solution, reducing crops yield. In this article, were revised studies that directly or indirectly address the effect of excessive fertigation and its contribution to the salinization process in soils under greenhouse, which showed information about the crops tolerance to salinization caused by fertilizers and their joint management with fertigation. Keywords: electrical conductivity; soil solution, fertilizers. DOI: http://dx.doi.org/10.14583/2318-7670.v02n03a10

O objetivo deste trabalho foi avaliar os parâmetros fitossociológicos de acordo com a estrutura tipológica de um fragmento de floresta a ser inundado pelo reservatório da UHE Sinop. Foi utilizado como parâmetro CAP (Circunferência a Altura do Peito) > 30 cm e mensuradas todas as árvores existentes nessa classe em 200 parcelas (10 x 250 m), instaladas aleatoriamente, nas margens direita e esquerda do rio Teles Pires (100 parcelas em cada margem). Foram estimados para cada tipologia os seguintes parâmetros: densidade por área, dominância absoluta, frequência absoluta e índice de valor de importância. Observou-se que os valores de densidade foram maiores para as Formações Ripárias, embora a Floresta Associada ao Planalto dos Parecis tenha amostrado um total de 11.265 indivíduos arbóreos. No que tange a frequência das espécies, destaque para Sapium longifolium que foi encontrada em todas as parcelas amostradas, seguida por Inga nobilis. Outra espécie que apresentou frequência significativa foi Duguetia lanceolata.

The CBH parameter (Circumference at Breast Height) ≥ 30 cm was used, and all existing trees in this class in 200 plots (10 x 250 m), randomly installed, on the left and right banks of the Teles Pires river (100 plots in each bank), were measured. The following parameters were estimated for each typology: density per area, absolute dominance, absolute frequency and importance value index. It was observed that the density values were higher for the Riparian formations, although the forest associated to the Parecis Plateau has totaled a sample of 11,265 trees. Regarding the frequency of species, one should highlight the Sapium longifolium, which was found in all sampling plots, followed by Inga nobilis. Another species with significant frequency was the Duguetia lanceolata.

RENDIMENTO E CUSTOS DO CORTE FLORESTAL NA EXPLORAÇÃO MADEIREIRA EM ÁREA DE MANEJO FLORESTALAvaliou-se a produtividade e os custos da exploração de madeira na floresta Amazônica, durante a realização das operações do corte florestal com a motosserra. O estudo foi conduzido em área de manejo florestal, floresta de terra firme, localizada no sul do Estado do Pará. Para a determinação do rendimento foram obtidos os volumes individuais das árvores exploradas e os tempos dos respectivos elementos do ciclo operacional do corte florestal. O custo de produção foi calculado pela razão entre os custos operacionais, fixos e variáveis, pelas horas efetivas trabalhadas. Foi realizada uma análise de correlação para a verificação da influência de propriedades físicas e mecânicas da madeira no tempo de derrubada das árvores. O ciclo operacional do corte florestal durou em média 31,5 min por árvore processada. As operações preliminares consumiram o maior tempo com 45,4% do tempo total, sendo o tempo médio por árvore de 14,3 min. A eficiência operacional do corte foi de 75% e a produtividade média de 20,15 m2 he-1, com custo por hora efetiva trabalhada de US$ 19,36. O custo de produção foi de US$ 1,18 m-3. As propriedades tecnológicas da madeira não explicaram estatisticamente as diferenças encontradas nos tempos de derrubada das árvores.Palavras-chave: floresta tropical, Amazônia, motosserra. ABSTRACTThe productivity and costs of logging in the Amazon rainforest were evaluated during the performance of the cutting forest operations with the chainsaw. The study was conducted in the forest management, upland forest, located in the south of Pará state, Brazil. To determine the income, individual volumes of the exploited trees were obtained and the time of each element of the operational cycle of the forest cutting. The production cost was calculated between the operational costs, fixed and variables by the worked hours. A correlation analysis was performed to verify the influence of physical and mechanical wood properties during the falling of trees. The forest cutting operational cycle lasted an average of 31.5 min per processed tree. Preliminary operations consumed the most time with 45.4% of the total time, with an average time of 14.3 min per tree. The operational efficiency of the cutting was 75% and the average productivity of 20.15 m3 he-1, with a cost of per effectively worked hour of US$ 19.36. The production cost was US$ 1.18 m-3. The technological properties of the wood did not explain statistically the differences found at the time of falling.Keywords: rainforest, Amazon, chainsaw DOI: http://dx.doi.org/10.14583/2318-7670.v04n03a05

O objetivo desse estudo foi avaliar as características mecânicas em tijolos fabricados a partir da mistura de solo, cimento e resíduo. O experimento foi realizado em Sinop-MT, o solo utilizado foi um Latossolo VermelhoAmarelo-Distrófico. O cimento utilizado foi o Cimento Portland (CP II Z-32) e o resíduo era proveniente de tornearia mecânica. Os tijolos de solo-cimento-resíduo foram fabricados com três teores de resíduo, 5, 10 e 15% e uma testemunha, sem adição de resíduo, foram moldados em prensa manual e mantidos em cura úmida durante 7 dias. Os ensaios de resistência à compressão simples e absorção de água foram realizados de acordo com a NBR 8.492 (2012). Em média os valores de resistência obtidos variaram de 0,33 à 0,45 Mpa. Os tijolos testados apresentaram capacidade de absorção variando entre 7 e 13%, ficando dentro do limite estabelecido pela pela NBR 8.491 (ABNT, 2012). Os tijolos fabricados a partir da mistura solo-cimento-resíduo não atingiram a resistência mínima exigida por norma, o mesmo foi observado nos tijolos sem adição de resíduo, independente da idade de ensaio.Palavras-chave: solo-cimento, sustentável, resistência, absorção. MECHANICAL CHARACTERISTICS OF ECOLOGICAL BRICKS WITH RESIDUE INCORPORATION ABSTRACTThe objective of this study was to evaluate the mechanical properties of bricks made from the soil mix, cement and residue. The experiment was realized in Sinop, MT, Brazil, the soil was a Red-Yellow-Dystrophic Latosol. The cement used was Portland cement (PC II-32 Z) and the residue was from mechanical turning. The soilcement-residue bricks were made with three concentrations of residue, 5, 10 and 15% and a witness without addition of residue were molded in a manual press and kept moist curing for 7 days. Resistance assays for compressive and water absorption were realized according to NBR 8492 (2012). On average resistance values obtained were 0.33 to 0.45 MPa. Tested residue levels have absorptive capacity varying between 7 and 13%, which was within the limit set by the NBR 8491 (ABNT, 2012). The bricks made from soil-cement-residue mixture did not meet the minimum resistance required as a rule, the same was observed in bricks without adding residue, regardless of age test.Keywords: soil-cement, sustainable, resistance, absorbency. DOI: http://dx.doi.org/10.14583/2318-7670.v04n03a10
