Machine learning has been greatly used in the field of image classification. Several machine learning techniques perform very well in this task. The development of machine learning technique in recent years are in the direction of deep learning. One of the main challenge of deep learning is that it requires the number of the samples to be extremely large for the model to perform well. This is because the number of feature that trainable parameter are huge. One of the solution to overcome this is by introducing transfer learning. One of the architecture that is currently introduced is Xception architecture. This architecture is claimed to outperform VGG16, ResNet50, and inception in terms of model accuracy and model size. This research aims to classify snakefruit quality by using transfer learning with Xception architecture. This is to explore possibility to achieve better result as Xception architecture generally perform better than other available architecture in transfer learning. The snakefruit quality is classified into two classes. Hyperparameter value is optimized by several scenario to determine the best model. The best performance is achieved by using learning rate of 0.0005, momentum 0.9 and dropout value of 0 or 0.25. The accuracy achieved is 94.44%.

Solid waste problem become a serious issue for the countries around the world since the amount of generated solid waste increase annually. As an effort to reduce and reuse of solid waste, a classification of solid waste image is needed to support automatic waste sorting. In the image classification task, image segmentation and feature extraction play important roles. This research applies recent deep leaning-based segmentation, namely pyramid scene parsing network (PSPNet). We also use various combination of image feature extraction (color, texture, and shape) to search for the best combination of features. As a comparison, we also perform experiment without using segmentation to see the effect of PSPNet. Then, support vector machine (SVM) is applied in the end as classification algorithm. Based on the result of experiment, it can be concluded that generally applying segmentation provide better source for feature extraction, especially in color and shape feature, hence increase the accuracy of classifier. It is also observed that the most important feature in this problem is color feature. However, the accuracy of classifier increase if additional features are introduced. The highest accuracy of 76.49% is achieved when PSPNet segmentation is applied and all combination of features are used.

Sheilahrusi, Priyanto JA, Rismiyati H, Rusmana I, Budiarti S. 2021. Short Communication: The potency of lytic bacteriophage isolated from various environments to control the growth of Citrobacter braakii causing urinary tract infection. Biodiversitas 22: 5550-5554. Citrobacter braakii is one of the pathogenic bacteria causing urinary tract infection (UTI) in humans. Bacteriophages that are specifically infecting C. braakii could be the alternatives to combat antibiotics resistance cases of this bacterium. This study aimed to isolate lytic phages from various environmental samples (tofu factory wastewater, sewage water, rice field water, fishpond water, cattle farm wastewater, and goat farm wastewater), and to analyze their effectivity to reduce UTI-causing C. braakii population in vitro. Results exhibited that phages targeting this bacterium were found in goat and cattle farm wastewater and not present in other samples. Two phages, namely FC1 and FC2, had different plaque morphology characteristics. The number of phages in cattle farm wastewater was 2.8 × 105 PFU/mL and 1.32 × 104 PFU/mL in goat farm wastewater. It was observed that the phages found in these environments also indicate the presence of their host. After 8 h incubation, FC1 and FC2 phage reduced UTI-causing C. braaakii population in vitro from 0.23×108 CFU/mL to 0.03×108 CFU/mL and 0.02×108 CFU/mL, respectively. The phages isolated from these two samples can be further developed for the treatment of UTI caused by C. braakii and goat and cattle farm wastewater treatment to prevent contaminating other areas.

Salah satu tugas Pengawas adalah melaksanakan supervisi di sekolah yang menjadi tanggung jawabnya. Supervisi sama sekali bukan penilaian unjuk kerja guru. Apalagi bila tujuan utama penilaiannya semata-mata hanya dalam arti sempit, yaitu mengkalkulasi kualitas keberadaan guru dalam memenuhi kepentingan akreditasi guru belaka. Hal ini sangat berbeda dengan konsep supervisi, secara konseptual, supervisi adalah serangkaian kegiatan membantu guru mengembangkan kemampuannya mengelola proses pembelajaran demi pencapaian tujuan pembelajaran. Supervisi merupakan upaya membantu guru-guru mengembangkan kemampuannya mencapai tujuan pembelajaran. Dengan demikian, berarti, esensi supervisi itu sama sekali bukan menilai kinerja guru dalam mengelola proses pembelajaran, melainkan membantu guru mengembangkan kemampuan profesionalismenya.Meskipun demikian, supervisi tidak bisa terlepas dari penilaian unjuk kerja guru dalam mengelola pembelajaran. Apabila di atas dikatakan, bahwa supervisi merupakan serangkaian kegiatan membantu guru mengembangkan kemampuannya mengelola proses pembelajaran, maka menilai unjuk kerja guru dalam mengelola proses pembelajaran merupakan salah satu kegiatan yang tidak bisa dihindarkan prosesnya.Penilaian kinerja guru dalam mengelola proses pembelajaran sebagai suatu proses pemberian estimasi mutu kerja guru dalam mengelola proses pembelajaran, merupakan bagian integral dari serangkaian kegiatan supervisi kunjungan kelas. Agar supervisi dapat membantu guru mengembangkan kemampuannya, maka untuk pelaksanaannya terlebih dahulu perlu diadakan penilaian kemampuan guru, sehingga bisa ditetapkan aspek yang perlu dikembangkan dan cara mengembangkannya. Kata Kunci: Pengawas, Supervisi dan Kinerja Guru

Character education is a system to instil character values to students including the components of awareness, understanding, consideration, and profound commitment in implementing those character values. The character education applies at Surakarta public secondary school (SMPN Surakarta) to encourage character values to students on the components of knowledge, awareness, and interest for God the Almighty, individual, other people, and society. Character education at schools closely relates to management or school evaluation that how character education is planned and applied properly at schools. In planning character education, it can immerse character values into learning. The implementation itself tries to integrate character education contents that have been formulated into all learning subjects. The integration is in all aspects of school daily basis life such as teacher role models in behaving and teaching. The success of character education is evaluated by the achievement of indicators of output competency standard such as performing religious teaching properly, following social norms, capable to think logically, critically, creatively and innovatively, mastering knowledge for further education, and understanding personal and people rights and obligations during the life of local and national society.
