    In this work, we carried out a numerical investigation of the PCF-SPR biosensor for the early detection of infected skin cancer cells and healthy cells. The study was conducted using the COMSOL Multiphysics-based FEM method. The dielectric material used in this PCF design is fused silica, while the plasmonic material is gold. The study was conducted to test the effect of the thickness of the plasmonic layer and the size of the air hole diameter on the PCF-SPR. It was found that the larger the diameter of the air hole in the proposed sensor gives a smaller confinement loss value, while the thicker the plasmonic material used also gives a small confinement loss value. The proposed PCF-SPR has a wavelength sensitivity in detecting skin cancer-infected cells of 7000 nm/RIU. These results indicate that the proposed sensor has a good performance in detecting cells infected with skin cancer.Pada pekerjaan ini kami melakukan investigasi numerik biosensor PCF-SPR dalam mendeteksi sel terinfeksi sel kanker kulit dan sel sehat. Penelitian dilakukan dengan menggunakan metode FEM berbasis COMSOL Multiphysics. Bahan dielektrik yang digunakan dalam rancangan PCF ini adalah fused silika, sedangkan bahan plasmonicnya adalahnya emas. Penelitian dilakukan uji pengaruh ketebalan lapisan plasmonic dan ukuran diameter hole udara pada PCF-SPR. Ditemukan bahwa semakin besar diameter hole udara pada sensor yang diusulkan memberikan nilai confinement loss yang semakin kecil, sedangkan semakin tebal bahan plasmonic yang digunakan memberikan juga nilai confinement loss yang kecil. PCF-SPR yang diusulkan memiliki sensitifitas panjang gelombang dalam mendeteksi sel terinfeksi kanker kulit sebesar 7000 nm/RIU. Dari hasil ini menunjukkan bahwa sensor yang diusulkan memiliki kinerja yang baik dalam mendeteksi sel terinfeksi kanker kulit

    Fiber Bragg grating (FBG) sensors have limitations in measuring high and extreme temperatures because in general FBG sensors are made of silica fiber, which at high temperatures can interfere with the mechanical performance of the materials. In this paper, we propose an S-FBG (Sapphire Fiber Bragg Grating) sensor which is resistant to extreme environmental influences and high temperatures. By developing S-FBG to measure high temperatures, it is found that S-FBG has high sensitivity, every 10C change is obtained and the Bragg wavelength shifts as far as 30.24 nm, this result is greatly influenced by the thermo-optic coefficient, and the coefficient of expansion-thermal. The design also evaluates the Gaussian apodization profile to improve sensor accuracy in monitoring temperature

    This study aims to improve learning outcomes of students through a learning model of problem-based learning on the sub-theme energy and change. This research was conducted in class III SD Muhammadiyah 4 Bandung and against the background circumstances of students are lacking in learning outcomes in the learning because teachers still use the learning that is conventional, that is, by using the lecture method, so that the involvement of learners in the learning was minimal. By using the model of Problem Based Learning can improve learning outcomes of students, because, in this model, the students become the center in the process of learning, stimulating learners to think critically, and to deepen their knowledge about what they know and what they need to know to solve the problem. In addition to its model of problem-based learning can also increase the activity and learning outcomes of students, help, develop skills to solve problems, and develop the skills to communicate orally. The conclusions obtained from this study is that the use of the model of problem-based learning can improve learning outcomes of students. Thus, the application of learning model problem based learning in sub-theme energy and amendments can be used as an alternative method of learning to be applied in Elementary School

    From 2015 to October 2020, there were 95 recorded conflicts between humans and elephants in six sub-districts in Pidie District, Aceh province. One of the sub-districts in the Tangse sub-district is Paya Guci village, an area of ​​the Transmigration Settlement Unit (UPT). Farmers in this area are very vulnerable to elephant disturbance, which causes economic losses and has adverse effects on human social life, culture, and survival. Lack of public understanding of ecology and behavior and efforts to mitigate conflicts between humans and elephants require training to increase knowledge, especially understanding how to prevent elephant disturbances by not killing, poisoning wisely, and trapping. The participatory discussion method was carried out for four days, from 2 to 4 December 2020, at the Paya Guci Transmigration Settlement Unit, Tangse District, Pidie Regency. This training uses the room method (delivery of material) and field practice. It can be said that the level of understanding of community members of the ecology, behavior, and habitat that elephants like is still low; after this activity, perceptions and attitudes that are compatible with the provisions of conservation emerge, how to control wiser elephants, so that a commitment is built to form a Care Community group jointly. Wildlife Conflict (MPKSL) at the village level. ---  Dalam kurun waktu tahun 2015 sampai dengan Oktober 2020 tercatat telah terjadi konflik antara manusia dengan gajah sebanyak 95 kali di enam kecamatan pada Kabupaten Pidie provinsi Aceh. Salah satu kecamatan adalah kecamatan Tangse desa Paya Guci yang merupakan kawasan Unit Pemukiman Transmigrasi (UPT). Kelompok petani pada kawasan ini sangat rentan dengan gangguan gajah yang tidak hanya menyebabkan kerugian secara ekonomi namun juga mengakibatkan efek negatif kepada kehidupan sosial manusia, budaya dan pada keberlangsungan hidup. Kurangnya pemahaman masyarakat terhadap ekologi dan prilaku serta upaya mitigasi konflik antara manusia dan gajah, diperlukan pelatihan untuk peningkatan pemahaman khususnya pemahaman terhadap bagaimana   melakukan tehnik pencegahan terhadap gangguan gajah secara bijak dengan tidak membunuh, meracun dan menjerat. Metode diskusi partisipatif dilaksanakan selama 4 hari yaitu tanggal 2 sampai 4 desember 2020 bertempat di Unit Pemukiman Transmigrasi Paya Guci Kecamatan Tangse Kabupaten Pidie. Pelatihan ini menggunakan metode ruangan (penyampaian materi) dan praktek lapangan. Dapat dikatakan bahwa tingkat pemahaman warga masyarakat terhadap ekologi, prilaku dan habitat yang disukai gajah masih rendah, setelah kegiatan tersebut muncul persepsi dan sikap yang bersuaian dengan ketentuan konservasi bagaiman tehnik penaggulangan gajah yang lebih bijak, sehingga terbangun komitmen untuk bersama-sama membentuk kelompok Masyarakat Peduli Konflik Satwa Liar (MPKSL) di tingkat gampung
