Anatomical and Histological Structure of Reproductive Organs in Male Flying Squirrel Hylopetes Lepidus (Horsfield, 1822)
No full textFlying squirrel (Hylopetes lepidus) is an Eutherial mamal (placental mammal), belong to the order Rodentia and belong to the family Sciuridae. Hylopetes lepidus had gray cheek as its unique characteristics. The reproductive organs are the key to success in maintaining the new descendants. Male reproductive organs will produce the male sex cells or spermatozoa. The purpose of the research is to examine the anatomical structure, morphometry, histomorphometry, and histological structure of male reproductive organs (penis, testicle, vas deferens, bulbouretralis gland, prostate and seminal vesicles) of Hylopetes lepidus. The method used in examining histological characteristics is Hematoxyin–Eosin staining method. The histological structure of reproductive organs were observed using optilab microscope. The results of the study showed that the adult male flying squirrel weighed 104.28 ± 0.64 gram. Anatomically, it has oval white reddist testicle. The testicle is located side out of the body cavity in the scrotum. Morphometric observation testicular showed that the right testes has volume 0.35 ± 0.07 ml, and the left has volume 0.35 ± 0.07 ml, weight of the right testicular 0.19 ± 0.01 gram, weight of the left testicular 0.18 ± 0.01 gram, diameter of the right testicular 6.35 ± 0.21 mm, diameter of the left testicular 6.35 ± 0.21 mm, short diameter of the right testicular 3.45 ± 0.21 mm, and short diameter of the left testicular 3.45 ± 0.21 mm. The diameter of tubulus seminiferus 261,4 ± 0.14 μm. The conclusion of this study compared to rodentia other testicular Hylopetes lepidus has a unique testicular bound by the connective tissue in the scrotum so that testicular included in class permanent descending testicular. The rhombus of the prostate gland are blunt, while histologically the sertoli cells in the seminiferus tubule shaped elongated, while in morphometry penis Hylopetes lepidus relatively longer than Mus musculus

Face Mask Wearing Detection Using Support Vector Machine (SVM)
No full textAs an effort to prevent the spread of the Covid-19, various countries have implemented health protocol policies such as work-from-home, social distancing, and face mask-wearing in public places. However, monitoring compliance with the policy is still difficult, especially for the face mask policy. It is still managed by humans and is costly. Thus, this research proposes a face mask-wearing detection using a soft-margin Support Vector Machine (SVM). There are three main stages: feature selection and preprocessing, model training, and evaluation. During the first stage, the dataset of 3833 images (1915 images with face masks and 1918 images without face masks) was prepared to be used in the training stage. The training stage was conducted using SVM added with the soft-margin objective to overcome images that could not be separated linearly. At the final stage, evaluation was conducted using a confusion matrix with 10 folds cross-validation. Based on the experiments, the proposed method shows a performance accuracy of 91.7%, a precision of 90.3%, recall of 93.5%, and an F-measure of 91.8%. Our method also worked fast, taking only 0.025 seconds to process a new image. It is 7.12 times faster than Deep Learning which requires 0.18 seconds for one classification
Artificial Bee Colony Algorithm to Solve the Shortest Route Problem with Fuzzy Arc Weight
No full textThe shortest path problem usually assumes a clear value (crisp) for the weights of each route. However, the crisp weight sometimes ends up ambiguous in practice in the daily life. The number of arc weights is calculated using fuzzy logic, α-cut fuzzy numbers. The Artificial Bee Colony (ABC) algorithm that adopts bee behavior in food searching is used to solve the shortest path problem. This study discusses how to solve numerical problems to find the shortest path using the Artificial Bee Colony algorithm if the arc weights are fuzzy numbers. The algorithm starts with finding the initial solution using Algorithm 1 and then calculated each distance using the sum of α-cut methods. After that, do a local search for each initial solution using the genetic algorithm mutation operator, then searched the distance amount using the same way then compared using the result of distance . The next step was to calculate the fitness value of each solution that would be used to calculate the probability value. The final step was to improve the solution, and an improved solution is said to be a solution if it does not improve again anymore. The calculation process was done repeatedly from the second step to the maximum iteration, i.e. when iteration had reached the limit or the iteration limit fails. Based on the calculation process using ABC algorithm in the case of numerical example, delivery of clean water supply in Gunung Kidul Regency, obtained the shortest route, that is route 1,2,3,5,6 with interval distance equal to 459, 9142
Limitations of Correlation Analysis in Analyzing The Relationship of God\u27s Close with His Servant
No full textHuman relationship with God can be described by human weakness and desire to serve the greater one. Weak humans need a protector and a place to complain about all problems. Not infrequently the problems of crushing life, despair, loss of hope and so on cannot be resolved alone. A place to complain about all the problems of life, without Him humans may lose their direction and purpose in life. It has become human nature created by Allah SWT, for the purpose of worshiping God. The human relationship with God is as a servant, so humans are obliged to worship Allah throughout their lives, because everything that humans do will be accounted for in the future. Correlation analysis is a statistical tool that can be used to determine the degree of linear relationship between a variable and another variable. Correlation can be positive or negative. Correlation analysis can only explain one correlation value, when the r value is positive then the relationship is positive or when the r value is negative then the relationship is negative, the r value cannot be both. Where as in Islam, the relationship between Allah and His servants can be positive or negative
