Mathematical Modeling on Assessing Rate of deforestation in The Sheka Forest South West Ethiopia
No full textDeforestation leads to increasing temperature and depletion of soil nutrients, to soil erosion, and to changes in local and, some evidence indicates, global climate. These environmental disruptions increase the risk to human populations from both natural and man-made disasters and the immediate risk-takers are the local population. Tropical deforestation has become a global concern, with an annual total forest loss of 9.4 million hectares. The total forested area of Ethiopia has decreased substantially during the past half-century and the recent figures show that the country’s forest cover has shrunk to less than 3–3.6%. Primary data was collected from the local community in addition to the secondary data about the forest. The growth rates of forestry resources and population density are assumed to be following the logistic growth model. The growth of forest resources is in the direct proportion of population density and population pressure. The mathematical model of a system of differential equations was solved using backward Euler’s method; the deforestation rate was decreased because of the NGOs and the government worked together to increase awareness to the community about the importance of the forest. The rate of deforestation is per population change, this indicates the rate of deforestation is decreased. Recommendations were given to the concerned body

No full textPt. Anugerah Putra Plating is one of the service companies engaged in the metal finishing industry or, more precisely Zinc Plating (zinc coating process that uses electricity) where the coating process is most widely used for small-sized goods with an extensive production scale and one of the products processed at PT. This Plating Son Award is a baseplate. Problems arising from defects are not up to the specified standards, triggering a decrease in product quality. The company produced baseplate from January 2020 to December 2020 of 53145 pcs, in that period, there were defects of 2980 pcs or 5.60%. The percentage exceeded the company's disability target of 3.50%. Based on direct observation of spaciousness and data processing using FMEA, it can be known that 4 types of defects are contained in baseplate products, namely White Rush, Oily, Black Spot and also Imperfect Coating. The most dominant defects are ranked 1 and 2, with the highest score is White Rush with a Risk Priority Number (RPN) score of 392. For this type of baseplate defect, the root of the problem is (1) Improper rounding distance, (2) unscheduled maintenance of the machine, (3) Improper chemical solution, and (4) a Dirty working environment. Proposed improvements based on the results of the analysis are as follows the types of defects White Rush: (1) Making hook hangers at a distance so that the hcl process is organized, (2) Made sterile storage space and also repair/inspection of routine machines, (3) Making the inspection sheet of chemical solution monitoring if this proposal can be carried out properly, the potential enough results that can be obtained is very - very more efficient and structured time, for the waste of costs can be emphasized to a minimum, as well as improve the quality of the product produced, so that it is expected that (estimate) the cumulative value of the company can increase by 1.8 from 5.6 - 3.8 (4)Apply pickets in the respective line - each after business hours
Development of Slims Framework Modification and Migration for Library Information System in Electrical Engineering Department, Diponegoro University of Indonesia
No full textMany libraries have been built for the library management system in a more active era of development, one of which is Slims. Slims is an open-source library management system that aims to simplify book search management while expanding existing capabilities. The Department of Electrical Engineering library initially used a PHP 4 website; however, in the present development, the library is innovating by adopting Slims based on PHP 7.4. The rationale for the change is that the former website had flaws, such as insufficient search tools, a lack of available book data, a less appealing website design, and a manual borrowing process. As a result, inventions and modifications are made to address these flaws. It's vital to map the previous data to make transferring data more accessible. Matching fields from several datasets into a schema or database is data mapping. Thus, innovation and modification are carried out to make it easier for librarians to maintain the library system
Nexus between Technology Adoption and the Development of Dairy Cooperatives in Kiambu County, Kenya
No full textCooperatives societies are part and parcel of an increasing number of people in formal and informal employment the world over. The study sought to examine the effect of the adoption of technology on the development of dairy cooperatives. Grounded on the Social Capital Theory, this study adopted the descriptive research design. In this study, the target population was 59,635 registered Dairy Cooperative members while the sample size was 398 respondents who were picked via stratified random sampling. Data collection involved questionnaires that contained 5-point scale Likert-type statements. Descriptive and inferential statistics were carried out. In this case, tests such as central tendency (mean), frequencies, percentages, and standard deviation in addition to Pearson and regression analysis were utilized. The findings show that the factor under investigation has a significant influence on the development of dairy cooperatives. This is evidenced by a positive and statistically significant relationship between technology adoption and the development of dairy cooperatives (r=.646, p<0.001). These findings are corroborated by results from multivariate regression analysis that shows that the technology adoption statistically significantly predicted the DV, F=68.052, p <0.05. This would go on to enhance their development. The study recommends that there is a need for dairy cooperatives to put in place mechanisms for buttressing access to technology. Further, the study recommends the need for policies to be in place to strengthen research on the challenges facing dairy cooperatives development. Policies should also be put in place to create a favorable environment for technology adoption

Inventory Control of Vegetable Oil Products Using Continuous Review System (Q) Approach and Periodic Review System (P) Methods in Retail Companies: A Case Study of Indonesia
No full textRetail companies are businesses that have a significant role in providing quality staples to improve public health. Every retail company wants the production inventory control system to run well to meet consumer demand. Suppose the amount of inventory in a retail company is too small. In that case, it will disrupt consumer demand for products that consumers want to buy and lose the opportunity to earn profits if an order is more significant than forecast. Meanwhile, if product inventory exceeds the need for a product, it will cause high costs, and if stock is stored for too long, it will result in damage and expiration. This retail company sells quality products and provides a wide range of excellent and complete products and makes it easier for customers to find their needs as one of the best. A company that needs to have a product control system to maintain sales and sell quality products and finally compete with other national and foreign retail companies. However, the current product inventory processing is not optimal because it is only based on previous inventory data. It can be seen from the varying amount of inventory and the high frequency of ordering. This study aims to obtain the most optimal comparison results by using the minimum total cost criteria and minimizing the cost of purchasing the product. This study compares two methods, namely the Continuous Review System (Q) method and the Periodic Review System (P) method. The most suitable method was the Q method with the total inventory cost of Vegetable Oil Products of Rp in this study. 13,371,600 with an efficiency of 42% of the entire inventory costs incurred by retail companies
Correlation of Pinch Properties with Minimum Pinch Radius in UNU/ICTP PFF for Different Pressure of Argon Gas
No full textIn this present work, numerical experiments are performed using the Lee code to examine the correlation of minimum pinch radius (rmin) with pinch energy density (PED), ion number density (Ni), induced voltage (Vmax), total radiation power (Prad) and Joule heating power (Pjoule) in UNU/ICTP PFF device when using argon gas at different pressure. The computed results show that at the optimum pressure of 1.0 Torr argon, PED (338 × 109 Jm-3), Ni (123 × 1023 /m3), Vmax (245 kV), Pjoule (114.48 × 108 W) and Prad (173 × 108 W) reach to their maximum values whilst the rmin reaches to its lowest value of 0.01 cm. At this optimum condition, due to strong radiation cooling effect is found and the excess (Pjoule - Prad) in radiative power of -58.51 × 108 W (negative singe indicates the energy going out from pinch plasma) which is sufficiently enough to cause the radiative collapse in heavier argon pinch plasma. Hence, the excess radiation power would be another reason for the occurrence of radiative collapse beside the critical (Pease-Braginski) current
Child-Friendly District Based on Local Potential: Study Implementation of Regent Regulation No. 12 of 2014 on Child-Friendly District Policies in East Kutai District
No full textThrough Regent Regulation No. 12 of 2014 concerning Child-Friendly District Policies, the East Kutai District Government together with all components of society, the business world, and the local press have committed to realizing East Kutai District as a "Child-Friendly District". However, in its implementation, it still faces problems, including cases of child violence, child marriage, child labor, and the negative impact of advances in information technology that makes children vulnerable to exposure to inappropriate information. Based on these problems, this study aims to describe and analyze the implementation of Child-Friendly District policies in the East Kutai Regency, and the supporting and inhibiting factors in the implementation of these policies. Through a qualitative approach, this research concludes: First, the implementation of Child Friendly District policies based on local potential in East Kutai Regency seen from the aspects of communication, resources, disposition, and bureaucratic structure can be said to be "successful" but "not optimal". Second, the internal factors that support the implementation of the KLA policy are: the existence of clarity in the goals, objectives, and stages of implementation; clear policy/program technical guidelines; a strong legal basis; implementing authority in accordance with the main objectives and functions; the existence of program innovation by the implementer; proper placement of implementers; and effective and efficient division of duties and responsibilities for implementers. The external factors that support the implementation of the KLA policy are the active participation of the community, a sizeable contribution from the business world, the involvement of the local press, and utilization of local potential in policy/program development. Third, the internal factors that hinder the implementation of the KLA policy are: the process of delivering information about policies/programs is still limited, the presence of implementers is not sufficient, the existence of infrastructure and facilities is not sufficient, the commitment of the implementers is still weak, and the absence of incentives for implementers, and the existence of SOPs have not been fully used as a reference in policy implementation. Meanwhile, the external factors that hinder the implementation of the KLA policy are: there are people who still do not understand the KLA policy/program, the role of the business world is still weak, and the press still does not understand KLA policy/program. Internal factors that hinder the implementation of the KLA policy are: the process of delivering information about policies/programs is still limited, the presence of implementers is not sufficient, the existence of infrastructure and facilities is not adequate, the commitment of the implementers is still weak, and there is no incentive for the implementers, and the existence of SOPs have not been fully used as a reference in policy implementation.

Analysis of Domestic Water Supply in Urban Area of Akinyele Local Government of Oyo State, Nigeria
No full textWater supply is paramount to human life because it prevents communicable and non-communicable diseases as well as contributes to socio-economic development and sustenance of cultural values (SDGs, 2016). This chapter highlights sources of domestic water supply in Akinyele LGA, Oyo State, Nigeria. The survey method was adopted by the administration of 399 copies of the questionnaire on households randomly selected in the urban areas of the LGA. The findings show that domestic water supply is more problematic during the dry season with 40% of the respondents not adequately getting potable water, accounting for 77% of the households experiencing typhoid, 11.4% contracting cholera, 8.6% having skin rashes, and 2.9% suffering from diarrhea in the past one year. Further analysis of the association between sources of water and socioeconomic variables indicates no significant association on whether improved or not improved sources with all values > 0.005. Education through public enlightenment on the use of improved water, provision of water facilities and involvement of private water providers, and willingness to pay for their services by households among others are advocated to remedy water problems in Akinyele LGA and, by extension, Ibadan metropolis as well as, other cities in Nigeria
