Rumah adalah bangunan yang dijadikan tempat tinggal selama jangka waktu tertentu. Namun ternyata belum banyak masyarakat mengetahui seperti apa kriteria rumah yang layak untuk dihuni. Saat ini masalah menyediakan rumah layak huni bagi masyarakat berpenghasilan rendah (MBR) masih menjadi permasalahan Pemerintah Indonesia dan Dinas terkait lainnya. Berbagai jenis bantuan perbaikan rumah layak huni atau bedah rumah telah banyak dilakukan berbagai pihak, baik oleh pemerintah maupun swasta. Akan tetapi bantuan yang diberikan relatif belum dapat memenuhi kebutuhan masyarakat dalam jumlah sasaran karena begitu banyaknya masyarakat yang mengajukan permohonan untuk bantuan bedah rumah tersebut. Sehingga dalam pemberian bantuan tersebut, perlu ditetapkan berbagai kriteria atau syarat sebagai standart penyeleksian agar penyaluran bantuan tepat pada sasarannya. Penentuan penerima bantuan bedah rumah yang didasarkan pada kriteria-kriteria tersebut sering kali menjadi masalah dalam proses pengambilan keputusan. Untuk mengekspresikan preferensi pengambil keputusan pada alternatif yang paling diinginkan, dapat dilakukan dengan menerapkan TechniqueÂ  For Order Preference by Similarity to Ideal Solution (TOPSIS). Metode TOPSIS akan di kombinasikan dengan logika fuzzy untuk menentukan nilai bobot pada setiap atribut kriteria, yang dilanjutkan dengan proses perangkingan untuk menyeleksi alternatif terbaik, dalam hal ini adalah alternatif yang valid sebagai penerima bantuan yang sesuai dengan kriteria. Dengan metode ini diharapkan proses penilaian akan lebih tepat dan akurat karena didasarkan pada nilai kriteria dan bobot yang telah ditentukan.

Predictive Influence of Proposed Rural Grazing Area (RUGA) on Communal Security in Ogun West Senatorial District, Nigeria
Authors: Abayomi Ogunsanwo  , Atinuke Ayo-Balogun
Published: August 2024

This study examines the predictive influence of the Nigerian government's Rural Grazing Area (RUGA) policy on communal security in the Ogun West senatorial district. Despite RUGA's aim to mitigate herder-farmer conflicts by establishing designated grazing areas, the policy faces significant opposition due to ethnic tensions, land use conflicts, and concerns about Fulani herder dominance. Using a mixed-methods approach, data were collected from 500 respondents across five local government districts in Ogun West. Quantitative analysis using regression models revealed that RUGA significantly impacts communal security (R = 0.728, R² = 0.530, p < 0.001), social harmony (B = 0.874, t = 25.537, p < 0.001), community engagement (B = 0.862, t = 29.741, p < 0.001), and ethnocentric, religious, and socioeconomic issues (B = 0.869, t = 29.278, p < 0.001). However, the policy does not significantly predict the readiness of nomads to settle (B = 0.032, p = 0.586) or the preparedness of local people to accept the scheme (B = 0.051, p = 0.366). These findings indicate that while RUGA has the potential to enhance social and community engagement outcomes, its success is hindered by the lack of readiness and acceptance among key stakeholders. The study recommends increased engagement and sensitization efforts to enhance nomads' readiness and local acceptance, ensuring the policy's successful implementation and contribution to inclusive economic development.

Effective reservoir characterization has been one of the major challenges encountered in the oil and gas industry. Several tools and models have been created to analyze a reservoir accurately to tackle this challenge. This paper reviewed using artificial intelligence and machine learning for reservoir characterization, which has proven an efficient method. With a good understanding of porosity and permeability, reservoir engineers can carefully create a sustainable reservoir development plan, create an effective production system for naturally unproductive reservoirs, determine the drilling optimization, estimate hydraulic flow units, choose the pressure-volume-temperature of reservoirs and reservoir rock properties such as porosity and permeability using well-log data. Support Vector Machines and Artificial Neural Networks from the studies have shown to be vital for a comprehensive reservoir analysis in the future, but there is a need to improve the algorithms for better optimization of new datasets.
Promoting Financial Accountability in Churches & Parachurch Institutions.
Authors: Shumbambiri Gregory
Published: August 2024

All organizations, including churches, must be transparent and responsible with financial resources to maintain confidence and the credibility of their stakeholders. Resource management for churches is an important aspect of the church’s supply chain because churches are obligated to take care of and manage member gifts and donations. It is imperative for churches to set explicit policies for the handling, documentation, and reporting of resources. These policies should address budgetary planning, spending approval, and the implementation of measures to prevent fraud and conflicts of interest. Additionally, churches have the freedom to release annual financial reports or updates that include financial data including sources of income, costs, assets, and liabilities. Annual budgets comprising estimated revenues and expenses are developed and presented to the leadership for review and approval. Churches have an opportunity to have outside professionals conduct an impartial review or audit of their financial records. Additionally, churches have the ability to form finance committees made up of knowledgeable and seasoned experts in human resources, accounting, taxation, and law who can provide expert counsel. A mechanism for tracking and recording member donations ought to be in place within the church. Information regarding the receipt and distribution of funds via various channels of communication should be transparent. Although the aforementioned is commendable, it should be highlighted that accountability by itself faces numerous difficulties, such as opposition to change and the aversion of the status quo to adopting novel approaches. An inability to establish appropriate financial management guidelines could also be the result of ignorance. Complicating matters is the fact that some volunteers may sincerely wish to help but lack the appropriate education and training. Members of the board, for example, who oversee the church's governance, may be financially illiterate. The Chairman's Role in Financial Accountability is only realised when there is an effective implementation of a meaningful mission through an effective board with people elected into offices with well-capacitated board members. Well-functioning boards have a stake in the church's ability to carry out its mission plan. This is accomplished by holding frequent meetings and aggressively managing essential operational tasks, such as monitoring the church budget.
THE ETHICAL IMPLICATIONS AND ECONOMIC IMPACT OF MARKETING MEDICAL PRODUCTS: BALANCING PROFIT AND PATIENT WELL-BEING
Authors: Patrick Azuka Okeleke  , Sodiq Odetunde Babatunde  , Tochukwu Ignatius Ijomah
Published: August 2024

The ethical implications and economic impact of marketing medical products are complex and multifaceted, requiring a careful balance between profit motives and patient well-being. As the healthcare industry continues to grow, the marketing of medical products has become increasingly influential in shaping consumer choices, prescribing behaviors, and ultimately, patient outcomes. This review explores the ethical challenges inherent in promoting medical products, such as the potential for misleading advertising, the prioritization of profit over patient health, and the influence of marketing on healthcare professionals' decision-making. One critical ethical concern is the possibility of misleading claims about the efficacy or safety of medical products, which can lead to inappropriate usage and adverse health outcomes. The aggressive promotion of certain drugs or devices, particularly in vulnerable populations, raises questions about the moral responsibilities of pharmaceutical companies and marketers. Additionally, the practice of direct-to-consumer advertising, particularly in markets like the United States, has been criticized for creating unnecessary demand and contributing to the over-medicalization of society. From an economic perspective, the marketing of medical products drives significant revenue for pharmaceutical companies and the broader healthcare industry. However, this economic impact must be weighed against the potential costs to public health, including the risk of side effects from over-prescribed medications and the financial burden on healthcare systems from inappropriate or excessive treatments. The economic incentives for companies to prioritize profitable products over those that may be more beneficial to patients pose a significant ethical dilemma. This paper seeks to examine these issues by analyzing the balance between ethical marketing practices and economic interests in the healthcare sector. It will explore case studies of marketing strategies that have led to both positive and negative outcomes, assess the role of regulation in mitigating ethical concerns, and propose recommendations for aligning marketing practices with patient well-being while maintaining economic viability. The goal is to provide a comprehensive understanding of how the marketing of medical products can be conducted responsibly, ensuring that profit motives do not compromise patient health..

INTER-RELATIONSHIPS AMONG STOCK MARKET FUNDAMENTALS : A SEARCH FOR EVIDENCES OF CAUSALITY, COINTEGRATION , COMPLEMENTARITY AND SUBSTITUTABILITY
Authors: Bernhard O. ISHIORO, Ph.D
Published: August 2024

This paper seeks to validate or otherwise the existence of causal, complementary, substitutability and cointegrating  inter-relationships  among the stock market indicators:  turnover ratio , that is, market liquidity,  volume traded, value traded and size of the stock market ,measured by market capitalization and the number of listed companies for the Nigerian economy for the  period 1985-2020.Maximising the time series characteristics of our data, we applied the unit root test as the starting point of our analysis; and was complemented with the Johansen bivariate cointegration test , and the long and short-run Granger causality tests.
The results obtained from the unit root test indicated that all the series were integrated of the same order. Principally, long-term causality was established between size and liquidity and number of listed companies without reverse causality from number of listed companies to either market capitalization, volume traded, value traded, and turnover ratio. In the short-term, bi-directional causality was established for value traded and market capitalization, turnover and capitalization, and value traded and turnover ratio. Furthermore, our results confirmed that in the long-term value traded complemented capitalization and the number of companies listed; turnover complemented the number of listed companies and volume traded; and volume traded complemented value traded while turnover substituted capitalization and value traded. Capitalization and other fundamentals that exhibited the tendencies of  complementarity should be enhanced to attract more listed companies into the market.

Authors: Ali Irfan , Hadiyanto Hadiyanto , Wardaya Asep Yoyo
Published: August 2024

The power generation sector significantly contributes to climate change. Mitigation efforts are crucial to adhering to the global commitment to limit temperature increases below 2°C. One potential solution is retrofitting existing power plants with technologies that integrate renewable energy. This study explores the integration of solar energy into the operational processes of a coal-fired power plant in Central Kalimantan, replacing the extraction steam turbine in the high-pressure feed water heater No. 7. Using STEAG EBSILON for simulation, this research evaluates the power plant's performance before and after retrofitting in both power-boost (PB) and fuel-save (FS) modes under varying load conditions. The results demonstrate that thermal efficiency in both PB and FS modes increased by up to 2% compared to the base scenario. Specific fuel consumption decreased by 15.05 g/kWh in PB mode and 15.75 g/kWh in FS mode, leading to a reduction in coal consumption and CO2 emissions by 4.69% and 4.94% respectively. Additionally, the study observed that the solar percentage and solar-to-electricity efficiency increased as the load decreased. In FS mode, the solar electricity proportions at VWO, 100%, 75%, and 50% load rates were 5.23%, 5.53%, 7.76%, and 11.92%, respectively. The levelized cost of energy (LCOE) for solar electricity was calculated to be 431.82 IDR/kWh, with an expected investment return period of 5.87 years.
Isolation, identification, and characterization of neopullulanase from Thermomonas hydrothermalis GKE 08
Authors: Yildiz Songul
Published: August 2024

The production of neopullulanase from thermophiles, such as Thermomonas hydrothermalis GKE 08, has great importance due to the enzyme’s unique thermophilic nature. This characteristic results in enhanced stability and functionality at elevated temperatures. It is known that this is a very important issue for industrial processes that require efficient catalysis under extreme conditions. The investigation of pullulanase from T. hydrothermalis GKE 08 showed significant results. Optimal conditions for enzyme production were determined, with peak activity observed in the presence of 1.5% soluble pullulan and 0.5% peptone. The study delved into the pH and temperature dynamics, identifying an optimal pH of 7.0 and a temperature of 55°C. Notably, the neopullulanase exhibited time-dependent stability, retaining 72% activity after 1 hour but declining to 50% after 2 hours. Purified pullulanase from T. hydrothermalis GKE 08 displayed optimal activity at pH 7.0, with a subsequent time-dependent decline observed during incubation at this pH: retaining 72% activity after 1 hour, approximately 50% after 2 hours, and a significant 77% loss after one day. Furthermore, the enzyme displayed remarkable thermostability at 60°C, with 88% activity after 30 minutes. Metal ion studies indicated susceptibility to inhibition by Cu2+, Mg2+, and Zn2+, while Ca2+ stimulated activity up to 138% at higher concentrations. The enzyme’s response to specific reagents revealed sensitivity to SDS and EDTA, while urea surprisingly enhanced activity to 85%. The study enhances understanding of pullulanase behavior, offering valuable insights for biotechnological and industrial applications.

Published: August 2024

This article is intended to assess the extent of avocado production and export as a source of prosperity for smallholder farmers in Wanging’ombe District, Njombe Region, Tanzania. The general objective of the study is to assess avocado production and export as a source of prosperity for smallholder farmers in Tanzania. The study was guided by absolute cost advantage theory and comparative cost advantage theory. With the use of the descriptive research design, the target population was small-scale farmers, employees from the OLIVADO industry, and Wards Extension Officers. 150 respondents from six wards in the Wanging'ombe area were chosen using simple random sampling and purposive sampling. The data collection methods used were questionnaires, interviews, and focus groups, and the analysis was conducted through quantitative methods. The findings show that many farmers in Waging’ombe district owned orchards of 1 to 5 acres only due to limited capital. This is because avocado cultivation strive well under commercial cultivation which needs high capital for purchasing quality propagates, fertilizers and agrochemicals which many farmers are unable to access, avocado farmers face significant production and export market challenges as a result of their lack of suitable farmer skills and knowledge, the primary marketing channel for avocado producers is wholesalers as Tanzania's northern region's export channel is fueling growth, the local market and, to a lesser extent, an export section is driving development in Southern Highlands and identified a low poverty rate amongst avocado growers which is a main indicator of a rising standard of living among avocado farmers. The study concluded that various agricultural institutions as well as the government have been participating and conducting various trainings to build the capacity of Waging’ombe avocado farmers as well as the distribution of fertilizers and quality seeds to produce crops with the required quality in the export market and thus find a market for exportation, increasing their income and reducing poverty in their areas. The study concluded that provision of education for international commercial terms for exporting agricultural products, increase subsidies to agricultural inputs, access to low-interest rate loans from financial institutions to support small avocado farmers, increase in whole sellers’ companies in the marketing channel to reduce bureaucracy, increase packaging quality of the avocado products, and improvement of infrastructure will be crucial to avocado farmers in Waging’ombe district.

A prematuridade é um verdadeiro problema de saúde pública, envolvendo diferentes atores da saúde. Ao nascer, o recém-nascido prematuro apresenta imaturidade em suas funções orgânicas, principalmente em seu sistema respiratório, cujo desenvolvimento não está concluído. Ele pode, portanto, receber tratamentos específicos e suporte respiratório desde o nascimento, se necessário. O fisioterapeuta tem papel essencial no cuidado ao recém-nascido prematuro. É realizado desde o nascimento, principalmente através da fisioterapia respiratória. Os resultados tendem para a hipótese de uma prática específica de cada hospital, influenciada pela formação seguida pelos fisioterapeutas e pela falta de literatura científica que permita convergir as práticas para um protocolo que inclua técnicas baseadas na evidência da sua eficácia (Evidência Prática Baseada). É necessário direcionar a investigação para uma análise da eficácia de cada técnica respiratória utilizada nos recém-nascidos para, em última análise.

Now days, the home environment is still much less supportive of life for the elderly, most elderly living at home need a companion to help them. Safety, health, happiness and independence will be difficult for them to get even the elderly will be further away from the surrounding environment. Based on population projection 2017 data there are 23.66 million elderly people in Indonesia and predicted in 2020 there are 27.08 million people elderly. Smart homes that are currently widely studied have not focused on elderly; most smart homes only provide a sense of security and convenience for adult residents. And this will be a problem that until now has not solved the improvement of human life through technology to get happiness, care and health especially for the elderly. In many cases of the elderly, it is easier to send them to live in a nursing home and that keeps them separated from their families for the rest of their lives. That's what makes them less happiness. Orange Technology is a collection of technological elements to improve human life by getting happiness, Care and health. This study reviewed the journals of scientific databases such as IEEE explore, ACM digital library and Proquest published from 2002 to 2017. From the search results obtained 54 papers that will answer the scientific questions of this research. The result of this research is a framework of smart house that has Sensor, Monitoring, Wireless, Scalability, Low cost, GPS and ease of installation and maintenance as components of smart house of orange technology for elderly.

Money is a tool used to carry out buying and selling transactions and has been used by all humans in every corner of the world. This definitely makes money a basic commodity for everyone, even for people with disabilities such as the blind. The blind's limitations in seeing are a problem in terms of communication so they only rely on their sense of touch and hearing. The weakness of the blind in seeing and identifying money can cause money to be exchanged, taken wrongly, or even deceived by counterfeit money when buying and selling. Referring to this, it is necessary to have tools that can make it easier for the blind to identify the authenticity of money and the nominal value of money. The aim of this research is to design a tool that can be used to detect the authenticity of the nominal value of Rupiah banknotes. This tool uses a TCS3200-DB color sensor to detect the color of banknotes, then the microcontroller converts it into RGB data and outputs it in the form of sound output.and an ultraviolet sensor to detect the authenticity of money.The result of this research is that the system can recognize the authenticity and nominal value of moneypaper, especially rupiah. This makes it easier for users, especially the visually impaired, to carry out buying and selling transactions so they don't make mistakesto give or receive money.

At Republic of Indonesia State Civil Service Agency in carrying out work, it is often found that problems both software and hardware are installed in the computer and must be resolved immediately. However, the handling of problems is still not good, where in the process of reporting complaints and requests, you still have to go by telephone or come directly to the IT staff office to notify complaints, as well as in manual records that affect company performance. All recording reports and problem calculations are still manual. This can have a negative effect, namely: there are problems that are at risk of being recorded repeatedly, so it takes a long time to provide reports to managers. Therefore, the authors submit a helpdesk information system application to solve the problems of complaints and employee requests so that they can be resolved quickly and can be handled properly as well as recording reports that are well recorded. In developing this helpdesk information system, the author uses an object-oriented methodology, namely the iteration waterfall, which is modeled using UML (Unified Modeling Language). The tools used are XAMPP as a web server, PHP as a programming language and MySQL as a database. With this system, it is hoped that it can make it easier for employees to report complaints as well as get solutions to the problems they are complaining about and also make it easier for IT staff to automatically generate reports in the system.

Published: August 2024

This research explains the application of sending data from various sensor nodes using the master-slave method in Long Range (LoRa) communication. This system was created to increase efficiency and reliability in collecting sensor data spread across several locations. Sensor nodes function as slaves that collect and send data to the master. The master then processes and combines the data before sending it to a central server. Experimental results show that this method is successful in reducing latency and increasing data transmission speed and shows great potential for Internet of Things (IoT) applications that require wide communication range and low power consumption.
Empowering Urban Farmers: An Asynchronous Learning Application for Greenhouse Management
Authors: Wibowo Mars Caroline , Santoso Joseph Teguh
Published: August 2024

This paper addresses the growing need for effective educational tools in greenhouse gardening, particularly for beginners lacking prior agricultural knowledge. Despite the increasing availability of mobile applications aimed at agricultural education, many existing resources fail to engage users through interactive experiences, thereby limiting their practical skill development. This study identifies a significant knowledge gap regarding the specific needs of novice gardeners and the effectiveness of current educational applications. To address this gap, we developed an innovative mobile application designed to facilitate asynchronous learning through interactive features such as discussion forums and quizzes. A mixed-methods approach was employed, involving user testing with 30 participants to evaluate the application’s usability and engagement levels. The results indicated that 90% of users found the application intuitive and easy to navigate, with enhanced motivation attributed to its engaging visual design. These findings suggest that the proposed application not only meets the educational needs of users but also fosters a more interactive and responsive learning environment. The implications of this research highlight the potential for mobile applications to significantly improve practical knowledge and skills in greenhouse management, ultimately contributing to more sustainable agricultural practices
