Mosques as public entities need good financial management. As a form of transparency and public accountability to the people. In its implementation, management is only managed simply, only recording income and expenses that occur at a certain time and submitting it as a report to the people. This form of transparency is manifested in the form of financial reports as an effort to be financially accountable to the people. This research is a field research with a qualitative descriptive approach and data was collected through direct observation, interviews with the management of the Al-Hajj Mosque. The results of the study show that the Al-Hajj Mosque keeps records based on income and expenses only without any grouping of accounts. The mosque's financial receipts come from local government subsidies, community donations and charity boxes which are distributed every Friday prayer. As for the mosque's financial expenses to finance operational expenses as well as incentives and fees. the management of the al-Hajj mosque does not know about the ISAK 35 standard, so that the presentation of the mosque's financial reports is not up to standard. The preparation of financial reports is still oriented towards the preparation of cash flow statements, where the financial reports are still only cash receipts and disbursements. Therefore researchers try to provide an overview related to ISAK 35 and implement standardized mosque financial reporting. The assets owned by the al-Hajj mosque cannot be fully described. The nominal value of the land and buildings owned is not included because this mosque is owned by the local government. The board only manages cash and cash equivalents originating from resource providers. As for debt, this mosque has no debt for the construction or operation of the mosque

Published: June 2023

Every issue we face in daily life can be resolved through mathematical modeling. The use of mathematical modeling to generate solutions frequently produces value that serves a single purpose. Sometimes a single-purpose function's solution does not offer the best solution value. In this study, the author models the multiobjective time-dependent vehicle routing problem using the Ant Colony Optimization (ACO) metaheuristic algorithm. The author then applies the pareto optimization principle to the determination of the optimal starting point for the route. An optimal Pareto frontier principle solution on a multi-objective model under control of the Ant Colony Optimization algorithm is the outcome of this study.

COMPARISON OF LASSO AND ADAPTIVE LASSO METHODS IN IDENTIFYING VARIABLES AFFECTING POPULATION EXPENDITURE
Authors: Rahayu Atika , Husein Ismail
Published: June 2023

Abstract: Since 2019, the difference in the increase in per capita expenditure of the population has continued to decline, and the most significant was only IDR 18,464 in 2021, indicating that the level of consumption of the population has not improved significantly, and the turnover of the community's economy is also not good. Multiple linear regression is more appropriate than other types of linear regression because it considers the influence of more than one independent variable on the dependent variable. However, problems may arise in the use of multiple linear regression, such as multicollinearity. To overcome this problem, other methods such as LASSO and adaptive LASSO should be used. Both methods have the ability to overcome multicollinearity between independent variables, thereby reducing the risk of misestimation. Nevertheless, the LASSO and Adaptive LASSO methods have differences in selecting important variables, so it is necessary to compare which method is better in terms of identifying influential variables. Based on the MSE and R-square comparison values, it is concluded that the Adaptive LASSO method model is the best model with a lower MSE value and a higher R-square value of 93%. The variable selection results of the Adaptive LASSO model are population size, number of households, average number of household members, constant price GDP, confirmed cases of COVID-19, human development index, percentage of the poor population, university student participation rate, and open unemployment rate.
DEVELOPMENT OF INDEPENDENT TAEKWONDO TRAINING MACHINE LEARNING WITH 3D POSE MODEL MEDIAPIPE
Authors: Santoso Billy Cahyo , Santoso Handri , Sandjaya Julio
Published: June 2023

Taekwondo is a martial art that focuses on punching and kicking movements while upholding the values of discipline, ethics, and good behavior. Discipline is built with routine training to make someone proficient in taekwondo martial arts. Training cannot be carried out flexibly because it must be accompanied by a sabouem to know the correct taekwondo movements. Machine learning can be used as a solution for taekwondo movement recognition by building a learning machine model that recognizes the correct taekwondo movement. The MediaPipe framework has the advantage of being able to recognize human posture with 33 points or landmarks. The research was carried out by conducting a literature study, where similar research was found but only based on the values of the x and y axes. So a problem arises where the majority of taekwondo movements require the z axis to know the correct taekwondo movements. The research was conducted to add z-axis values and change calculations, which were adjusted to reconstruct a training data object in the form of an image into a three-dimensional shape. From this study, it was found that machine learning using the x, y, and z axes is much better for its use, especially when detecting taekwondo movements from different viewpoints from the training data. This research can be developed by enlarging the image dataset and packaging the model into a mobile application so that it can be used for taekwondo training up to taekwondo movement assessment.

Published: June 2023

El crecimiento social y económico tiene una alta influencia en el incremento en la demanda energética, principalmente, la carga térmica de refrigeración. El bambú, como material ecológico, ha sido utilizado como elemento de construcción en tiempos antiguos, por ende, este estudio se realizó para evaluar el rendimiento energético de los cerramientos a base de bambú en una residencia bajo el clima tropical de la Ciudad de Panamá. Por medio de una revisión bibliográfica se obtuvieron las propiedades térmicas de tres configuraciones de bambú. Dichas datas fueron subidas al software DesignBuilder en donde se encontraba el modelo de la residencia. Se realizaron simulaciones bajo un análisis paramétrico evaluando las variables de entrada conformadas por 11 materiales de la envolvente formados por materiales de construcción convencionales y biocompuestos de bambú. Las variables de salida fueron las cargas térmicas a través de techo, paredes y cielo raso y las horas de no confort térmico a 80% de accesibilidad de la norma ASHRAE 55. Para el mes más caluroso (marzo), la carga térmica a través de paredes para las tres configuraciones de bambú fue de 48 KWh, resultando ser 3 veces menor que las cargas térmicas a través de las paredes con materiales convencionales. La carga térmica a través de techo y cielo raso fueron insignificantes ya que el diseño con materiales convencionales del techo favorece la pérdida de calor. Se alcanzaron condiciones de confort constantes anuales y la reducción de la carga térmica en la residencia.

Published: June 2023

El objetivo de esta investigación fue de evaluar si se puede obtener una mejora en la resistencia a compresión y flexión al sustituir un porcentaje del agregado fino de una mezcla de concreto por vidrio reciclado molido. La metodología utilizada consistió en la realización de un diseño de mezcla patrón de concreto convencional de f´c=28 MPa y su comparación con dos mezclas con el mismo diseño, pero con 10% y 15% de reemplazo del peso del agregado fino por vidrio reciclado molido. Tomando como base las normas técnicas de la ASTM, se confeccionaron un total de 75 cilindros de concreto para evaluar las resistencias a compresión a edades de ensayo de 3, 7, 14, 21 y 28 días; y un total de 18 viguetas para evaluar las resistencias a flexión a edades de ensayo 3, 14 y 28 días.  Para cada edad de ensayo, tanto a compresión como a flexión, hubo un incremento de resistencia en las mezclas con 10% de vidrio como reemplazo del agregado fino comparado con la mezcla de concreto patrón; sin embargo, este incremento no fue significativo para las resistencias a flexión. Las mezclas con 15% de vidrio como reemplazo del agregado fino presentaron resistencias menores a las de la mezcla de concreto patrón. Se llega a la conclusión que, el porcentaje de reemplazo ideal para este estudio es del 10%; toda vez que el 15% afectó negativamente la resistencia del concreto.

Scholarships for international students as a way to ensure the right to education (including case studies)
Authors: Sitnikova Valeriya
Published: June 2023

Access to education is recognized in several international human rights instruments, including the Universal Declaration of Human Rights and the International Covenant on Economic, Social and Cultural Rights. However, for many people, especially those from marginalized communities, access to education can be difficult due to financial, cultural and language barriers. In response to these challenges, there is growing recognition of the importance of scholarships and financial aid in expanding access to education for international students. Previous research has shown that scholarships can play a critical role in overcoming financial barriers and expanding access to education. For example, a study by the Organization for Economic Co-operation and Development (OECD) found that increased investment in education, including scholarships and financial aid, is associated with higher economic growth (below we will write in more detail about this study). In this article, we will take a fresh look at the importance of the right to education and the role that scholarships for international students can play in securing and protecting this right. We will also discuss the challenges international students face in accessing higher education and the impact of scholarships in overcoming these barriers. Ultimately, this article will demonstrate how scholarships for international students can be a valuable tool in ensuring access to education for all and ensuring that everyone has the opportunity to realize their right to education. Moreover, we will also look at several case studies to analyze the impact of scholarships on the lives of specific students from low-income countries. In addition, this article will show the correlation between granting scholarships and the economic growth of the countries (scholarship providers) as well as their receiving additional and unobvious at-first-sight political benefits.

Dalam suatu perencanaan pekerjaan proyek konstruksi pasti sangat berhubungan dengan Menajemen konstruksi yang berperan dalam pelaksanaan suatu proyek pembangunan dan bertujuan dalam mengelola pelaksanaan proyek konstruksi yang mencakup waktu pelaksanaan, biaya, hingga mutu bangunan konstruksi dari awal pekerjaan sampai dengan akhir hingga meperoleh hasil yang sesuai dengan perjanjian awal yang di inginkan oleh pemilik proyek (Owner). Pada pekerjaan proyek konstruksi Taman Marga Satwa Budaya Kinantan (TMSBK) Bukittinggi berjalan sesuai dengan rencana akan tetapi ada beberapa faktor yang harus di perhatikan agar pekerjaan tidak mengalami keterlambatan salah satunya faktor cuaca. Untuk mengatasi agar tidak terjadi keterlambatan maka dilakukan penambahan waktu jam kerja menggunakan metode Critical Path Method (CPM) biasa disebut jalur kritis. Hasil akhir dari kajian ini adalah menentukan Jalur kritis pada pembangunan kandang tahap 2 terdapat pada kegitan A-B-C-D-E-G-I, pekerjaan proyek konstruksi pada pembangunan kandang tahap 2 diselesaikan dengan waktu 95 minggu dan besar biaya proyek Rp13.852.312.887,- setelah dilakukan penambahan waktu jam kerja 1 jam maka pekerjaan proyek dapat diselesaikan 81 minggu dengan besar biaya proyek Rp Rp13.924.110.709,- dan selisih anggaran biaya biaya Rp78.978.000,- biaya Cost Slope Rp5.641.285,- dan penambahan waktu 3 jam kerja maka pelaksanaan proyek dapat dilakukan 72 minggu dengan besar biaya proyek Rp13.930.866.682,- dan selisih anggaran biaya Rp86.409.000,- biaya Cost Slope Rp3.756.913,-. Jadi semakin bertambah waktu maka otomatis biaya juga akan bertambah.Kata Kunci      : Perencanaan proyek, Keterlambatan proyek, Percepatan waktu dan biaya, Critical Path Method (CPM)
ANALISIS PERBANDINGAN TEBAL PERKERASAN LENTUR METODE ANALISA KOMPONEN BINA MARGA DENGAN METODE DESAIN PERKERASAN JALAN MDPJ 2017 ( STUDI KASUS : JALAN KURAI MUDIAK LIKI SULIKI )

Road infrastructure development has an important role as a supporter of social and economic activities in the community. However, there are still areas in West Sumatra, one of which is on Road Kurai Mudiak Liki, 50 Regency. Road Kurai is a connecting road between villages in the 50 Regency District which is still in the form of land and has a narrow width. In an effort to improve the condition of the Kurai road, it is necessary to plan for the highway by taking into account the vehicle load, weather, pavement material and soil carrying capacity. The bearing capacity of the subgrade is determined by the value of the California Bearing Ratio which greatly determines the thickness of the pavement layer because it will become the flexible pavement foundation that will be planned. Meanwhile, vehicular traffic, vehicle dimensions and payload will cause a compressive force on the vehicle axle which is supported on the road pavement which is channeled to the subgrade which is also an important reference in determining the thickness of the pavement. This study aims to determine the planning of flexible pavement thickness using the SKBI component analysis method 2.3.26.1987 and the 2017 Road Pavement Design Method No. 02/M/BM/2017 on Road Kurai Mudiak Liki Suliki. To find out which method is stronger for traffic load. The higher the traffic load, the thickness of each layer is important. Based on the calculation results of the two methods, the results obtained in the Component Analysis Method, namely Laston = 11.25 cm, Upper Foundation Layer = 15cm, Lower Foundation Layer = 20cm, and Road Pavement Design Method 2017 obtained calculation results AC-WC = 4 cm, AC-BC4 =6cm, AC-BC or AC Base =7.5cm, CTB3=15cm, Class A Aggregate Foundation=15cm.Keywords: Component Analysis Method, Road Pavement Design Method 2017, Road Kurai Mudiak Liki Suliki

Sebuah perencanaan sesuatu konstruksi pengendalian sedimen (Checkdam) dalam mengurangi sedimentasi yang terjadi. Dam Pengendali (Checkdam) merupakan salah satu bangunan yang berperan dalam mengelola dasar sungai dan berfungsi sebagai pengendali aliran debris dengan cara menampung, menahan dan mengontrol aliran debris. Perencanaan ini dilaksanakan karena sangat dibutuhkan untuk mengairi kawasan pertanian. Disaan debit air di sungai naik,sedimen sangat banyak terbawa air mengendap. Dan kadang dinding saluran sering jebol dan aliran air putus ke persawahan. Itulah alasan bangunan check dam ini di buat. Angka Froude tertinggi terdapat pada bangunan segiempat dengan nilai Fr = 0,0036 pada waktu (t) = 2 menit dan kecepatan 0,003 m/s. Dari bilangan Froude diatas dapat diketahui bahwa semua bentuk checkdam memiliki aliran subkritis. Kecepatan aliran tidak mempengaruhi angka Reynoldnya. Angka Reynold tertinggi terdapat pada bangunan check dam tipe Segiempat dengan Re = 291 dengan waktu 2 menit. Dari angka Reynold tersebut dapat diketahui bahwa semua bangunan memiliki pola aliran laminar. Angka tertinggi tegangan geser terdapat pada bangunan tipe segiempat dengan nilai 4,41 kg/m2. Angka tertinggi tegangan kritis terdapat pada bangunan tipe segiempat dengan nilai 36,383  kg/m2. Kata Kunci: Check Dam, Froude, Kecepatan Aliran, Reynold
