The purpose of this research to revisits methods that are more effective in nonlinear Optimization with single variable polynomial functions at high degrees. Models with linear objective functions and constraint functions are Polynomials of third, fourth and fifth degree reconstructed into subproblems that are easier to solve, namely quadratic programs, using bilinear Auxiliary Functions and solved by MATLAB simulations. The method used is the development of Tawarmalani & Sahinidis' research regarding relaxation with Auxiliary Functions. Examples of nonlinear Optimization with polynomial functions are also given to illustrate the implementation of this algorithm. The results of the research show that the application of the development reconstruction method produces a global solution that is no better than the solution to the original problem so that it is not an effective alternative method to use.

The ease of using Smartphones and the many functions that help with activities, make today's teenagers very familiar with Smartphones, including students at SMP Negeri 1 Tantom Angkola. Students tend to use Smartphones for various reasons, such as just wanting to play games and being too active on social media. The impact of Smartphone dependence, especially on student development, will have a negative impact from an academic point of view. The nature of dependence does not just happen, the influence of one another is certainly interconnected or correlated and forms a causal relationship. This paper aims to see how much influence Smartphone dependency has on the learning behavior of students at SMP Negeri 1 Tantom Angkola and which variables have the most influence on the learning behavior of SMP Negeri 1 Tantom Angkola Students. The method used in this study is the Path Analysis method. Path Analysis is a technique for analyzing causal relationships that occur when exogenous variables affect endogenous variables, not only directly but also indirectly. Path Analysis is used to determine the direct and indirect effects of exogenous variables on an endogenous variable which is reflected in the path coefficient. From the research results, it is obtained that the direct influence of social media variables  on learning behavior  = 44.9%, the large direct influence of online game variables  on learning behavior  = 40.7%, the direct influence of internet data package variables  on learning behavior  = 0.4%, the direct effect of school control variables  on learning behavior  = 85.2%. Then the variable that has the greatest influence on learning behavior is the school control variable with a value of 85.2%.

This study aims to analyze the optimality of a quadratic program model using the penalty function. The analysis is carried out in each case that has been made so that in each case optimal results are obtained. There are many methods that can be used to solve the quadratic program problem but in terms of the number of iterations, this research uses the penalty function and then implements it into the Matlab programming language. The results obtained in this study indicate that by using the penalty function as a parameter, the optimal value of a function can be obtained. The results of the analysis will also be more optimal by using the lagrange method depending on the parameter values obtained.

The method fuzzy is one part of the fuzzy inference system that is useful for drawing conclusions or the best decision in uncertain problems. Currently, about 200 countries in the world are experiencing the Covid-19 pandemic. Various policies were carried out to overcome this. In addition to the health protocols that are always implemented, the community must also know the conditions of the area where they live so that they can anticipate any activities carried out. The method is used fuzzy to determine the risk zone for the spread of Covid-19 in North Sumatra Province based on 3 variables, namely positive cases, suspected cases, and dead cases. The data used in this study is weekly Covid-19 data from March 2021 to July 2021 for 4 selected areas, namely Medan City, Pematang Siantar City, Simalungun Regency, and Central Tapanuli Regency. All variables are represented using triangular curves and their membership functions are determined. Then the implication function of the min is used to determine the rules used. From the results of the implication function, the composition between all the rules obtained is carried out by taking the maximum rule then that value is used to modify the fuzzy area so that a new membership function is obtained. The method is used centroid to obtain a crisp or the final result is the value of the risk zone. This research also utilizes the Matlab to calculate the results. The results from the use of the Mamdani method will be compared with the real risk zone data so as to produce a 75% average percentage similarity for the data for 4 regions in North Sumatra so it can be concluded that the model made is good enough to determine the risk zone for the spread of Covid-19 in North Sumatra Province.

The Erlang distribution is a special case of the Gamma distribution with the k shape parameter and the λ rate parameter. In this study, the parameter estimation of the Erlang distribution was carried out using the Maximum Likelihood method. In maximizing the function, an implicit and non-linear form is obtained, then it is solved using the Newton Raphson algorithm. Apart from Newton Raphon, the estimation of parameters was also carried out using the Fisher Scoring algorithm. The Fisher Scoring algorithm is similar to the Newton Raphson algorithm, the difference is that Fisher Scoring uses an matrix information. The result of parameter estimation in Erlang distribution using Newton Raphson algorithm which is applied to outgoing telephone call data that generated by Matlab R2010a software cannot be done simultaneously. Therefore, the parameter assessment is carried out on the k parameter first, then followed by the λ parameter estimation and the parameter and  = 0.6886812 are obtained. Meanwhile, the parameter estimation using the Fisher Scoring algorithm produces an equation that is not different from the Newton Raphson algorithm

Food and agricultural products are perishable, so they have the potential to experience losses, both in quality and quantity during the post-harvest process and processing due to physiological changes in the form of physical, chemical and microbiological. As an effort to reduce losses during post-harvest and physiological changes, it is necessary to apply appropriate technology (appropriate technology). The application of ozone technology in the handling of fruits, vegetables and fishery products has good prospects because it is felt to be safe and effective. Ozone (O3) has the main function, namely as an oxidizer and disinfectant or a combination of these two functions. The high oxidation potential of ozone can be used to kill bacteria (sterilization process), remove color (decolorization process), remove odors (deodorization process), and decompose organic compounds (degradation process). The treatment of ozonized water in the storage of food products and agricultural products does not damage their nutritional content, because the ozone content itself will be lost by evaporation. If ozone is exposed to sunlight it will break down into oxygen compounds again. Utilization of ozone technology is widely used to reduce contamination and extend the shelf life of fresh fruit, vegetables and fishery products. This paper examines and synthesizes several research results related to the use of ozone for fruits, vegetables and other agricultural commodities during the postharvest process and handling of agricultural products.

Puskesmas as a provider of basic health services has a very important role in maintaining public health. If it functions properly, the puskesmas will be able to provide quality services for people in need. The success of puskesmas in carrying out their programs is determined by the availability of human resources (HR) that are balanced between medical personnel on one side and promotive and preventive personnel on the other. The relationship between ability, workload, work discipline, and work motivation with the performance of health workers is obtained that there is a relationship between ability, workload, work discipline, and work motivation with the performance of health workers. Research Objectives: The purpose of this study is to analyze the suitability of the main tasks and functions (tupoksi) with education and skills as well as means of supporting work. Research Methods: The author of this article uses a descriptive qualitative method that seeks to describe an object or subject of an inductive nature. Result: Inappropriate tupoksi due to limited health workers in puskesmas, especially limited skills based on the type of education.

Conclusion: The lack of health workers makes the tupoksi incompatible with the educational background of the staff in charge of the program at the Puskesmas.

This research to analyze the contribution of variables from three economic policies, with monetary policy through interest rate variables, exchange rates, and money supply in facing economic recession. Where the fiscal policy variable is through tax value. Then macroprudential policy through Non Performing Loan and Capital Adequacy Ratio variables. This study uses secondary data or time series, namely from December 2019 to February 2021. The data analysis model in this study is the Vector Autoregression (VAR) model which is seen from being sharpened with Impulse Response Function (IRF) analysis and Forecast Error Variance Decomposition (FEVD), Panel ARDL, and Different Tests. The results of the IRF analysis show that the stability of the response of all variables is formed in period 8 or the medium and long term, where the response of other variables to changes in one variable shows different variations, both from positive responses to negative responses or vice versa, and there are variables whose responses remain positive or remain negative from the short term to the long term. The results of the FEVD analysis show that for the short-term inflation variable it is influenced by inflation itself and in the medium and long term it is influenced by interest rates. For the JUB variable in the short term it is influenced by JUB itself and in the medium and long term it is influenced by NPL. For the interest rate variable in the short term it is influenced by JUB while in the medium and long term it is influenced by the exchange rate itself and CAR. For the tax variable in the short, medium and long term it is influenced by the tax itself and JUB. For the NPL variable in the short, medium and long term it is influenced by JUB and tax. For the CAR variable in the short, medium and long term it is influenced by JUB and tax. Then the results of the ARDL Panel analysis show that the country that is able to become a leading indicator in controlling the economic recession in the Four of The Group Twenty, namely Turkey, is only done by interest rates. While South Africa is done by interest rates, taxes, NPL, and CAR. For Russia, it is done by all variables, namely the amount of money in circulation, interest rates, exchange rates, taxes, NPL, and CAR. Meanwhile, Indonesia is carried out by exchange rates, taxes, NPL and CAR.

Stroke is the number one cause of disability and the second cause of death in the world. Blood flow that is not smooth in stroke patients causes hemodynamic disorders including changes in the value of oxygen saturation in the blood (SpO2) which can interfere with the function of internal organs including the heart due to lack of oxygen intake. So we need a system to monitor the oxygen saturation value which can be used as an early indicator in recognizing stroke patients. This system uses detection of two sensors to measure oxygen saturation in the blood, a microcontroller to process data, a monitor to display data, a buzzer as a warning of the lower limit of measurement and a micro sd card module to store measurement data that has been running. Parameters displayed include the date of measurement, patient ID, SpO2-1, SpO2-2, last SpO2-1 and last SpO2-2. This system will measure and display the SpO2 value of both right and left arms simultaneously. Stroke patients who experience muscle weakness in one hand may experience different values with a hand that does not experience muscle weakness. This study aims to develop an SpO2 monitoring system that will be used to detect stroke patients with non-invasive methods. The results show that the system has been developed and can be used to measure the patient's SpO2 from both hands simultaneously with a measurement error rate of ±2% for each sensor from standard medical equipment.

This study explores how the Qadiriyya–Naqshbandiyya Suryalaya Sufi Order (TQN Suryalaya) integrates spiritual practice and metabolic health to strengthen community resilience during the COVID-19 pandemic. While global health responses have largely focused on biomedical interventions, this research emphasizes the complementary role of faith-based practices in promoting holistic well-being. Using a qualitative methodology—including in-depth interviews, participant observation, and document analysis of the 2020 Maklumat and Abah Aos’s letter to the President—the study identifies two interrelated pathways that underpin the Sufi lifestyle. The psychospiritual pathway encompasses the reduction of death anxiety through tawakkul (trust in God) and riḍā (contentment), emotional stability via dhikr (remembrance of God) and muraqabah (mindful awareness), and theological framing that interprets fear of Allah as the ultimate form of protection. These practices helped practitioners reframe pandemic-related uncertainties, mitigate stress, and foster emotional resilience. The metabolic pathway involves dietary simplicity, moderated caloric intake, physical worship routines, stress management, and structured sleep hygiene. Together, these elements supported immune competence and physical health, aligning with contemporary models of psychoneuroimmunology and holistic health promotion. Findings reveal that the TQN lifestyle does not only enhance individual mental well-being but also fosters social solidarity through communal worship, mutual aid, and spiritual counseling, thereby functioning as a culturally embedded form of faith-based social welfare. The study highlights the policy potential of incorporating Sufi practices into community health strategies and enriches interdisciplinary literature on religion, resilience, and social welfare. This dual-pathway model demonstrates that Sufi traditions can play a critical role in mitigating both the psychological and physiological impacts of global crises.
