Abstract

Community service activities for Muhammadiyah Elementary School Teachers in Polokarto Subdistrict, Sukoharjo Regency have been carried out. The background of this activity is the information obtained that the teachers in the school still use books and blackboards especially for subjects related to Science so that students become less creative and innovative thinking. activities carried out in the form of ongoing activities, namely training in the use of props style, motion and energy as many as 10 kits, presentation of the results of the practice of using props and the process of dissemination to students. The results obtained that all participants in understanding the teaching aids that have been trained, seen from the activeness of the participants, the ability of participants in the presentation and the results of dissemination to students in their respective schools

Abstract

Upaya untuk menyongsong era revolusi Industri 4.0 berupa peningkatan daya kreasi, inovasi serta kerjasama telah dilakukan melalui kegiatan seminar dan pelatihan terbimbing bagi guru IPA SMP dan MTs Muhammadiyah se Cabang Blimbing, Sukoharjo. Seminar dilakukan dengan mengupas berkaitan dengan revolusi industri 4.0, tantangan serta kiat-kiat dalam menghadapinya. Salah satu upaya untuk menghadapinya adalah melalui pelatihan pemanfaatan media alat peraga. Sebelum kegiatan dilakukan diperoleh informasi minimnya alat peraga yang di miliki pihak sekolah sehingga guru dalam penyampaikan materi menggunakan buku dan papan tulis saja, pelatihan yang dilakukan di khususkan untuk materi kelistrikan menggunakan Peraga kit listrik SEQIP, hasil dari pelatihan semua Guru dapat  memanfaatkan alat peraga kelistrikan dengan mudah, untuk topik percobaan yang dapat dilakukan berupa rangkaian listrik sederhana, rangkaian paralel, rangkaian seri, konduktor dan non konduktor, aplikasi energi listrik dan pembangkit energi listrik menggunakan dinamo.

Abstract

Sistem neuromuscular terdiri dari saraf motorik dan otot rangka yang menghasilkan aktivitas kelistrikan pada otot dan menyebabkan otot dapat berkontraksi dan menghasilkan gerak tubuh. Gangguan neuromuscular dapat terjadi pada sel saraf yang dinamakan Neuropathy dan pada sel otot yang dinamakan Myopathy. Aktivitas kelistrikan pada otot direkam melalui suatu alat yang dinamakan Electromiography (EMG). Pada penelitian ini dilakukan identifikasi sinyal EMG pasien sehat, myopathy dan neuropathy. Neuropathy merupakan gangguan yang disebabkan oleh kerusakan sel saraf. Myopathy merupakan gangguan yang disebabkan oleh kerusakan sel otot. Penanganan dan pengobatan myopathy dan neuropathy berbeda, sehingga diperlukan suatu metode yang dapat mendiagnosis dengan tepat jenis gangguan yang dialami. Analisis karakteristik sinyal EMG dilakukan menggunakan metode dekomposisi Wavelet Discrete Dyadic dan variasi fitur Root Mean Square (RMS), approximate entropy, spectral entropy dan Singular Value Decompotition (SVD) entropy. Sinyal karakteristik yang diperoleh di identifikasi menggunakan metode klasifikasi Adaptive Neuro Fuzzy Inference System (ANFIS). Performa ANFIS dalam mengidentifikasi karakteristik sinyal EMG pada masing-masing koefisien dekomposisi, menghasilkan performa terbaik pada koefisien aproksimasi ke-5 (cA5), dengan akurasi 100%, sensitivitas 100% dan spesivitas 100%.

Abstract

Fluid flowing in a cross-section of a channel follows the law of continuity, namely the mass rate of fluid entering will be the same as the mass rate of fluid leaving. One of the applications of fluid flow is in human blood flow. Blood flow is controlled by the heart which functions to pump blood to and from the heart. The flow of blood entering and leaving the heart is determined by the cross-sectional area of the channel and the speed of blood flow through the heart. The speed of blood flow in the heart consists of two speeds, namely the systolic speed when blood leaves the heart and the diastolic speed when blood enters the heart. So that the volume in the heart can be observed changes over time. By creating a simulation using the MATLAB programming language, the difference between normal heart volume and problematic heart volume can be known. A program called reservoir and cardiac based on graphical user interface was created to determine the volume of fluid in the reservoir at any time and compare the volume of fluid in normal and abnormal hearts concerning time in 1 systole-diastole cycle.

Abstract

Phantoms are used to research image quality and the amount of attenuation as an organ simulation. If done in the human body, it would be hazardous. High radiation exposure can damage cells. Therefore, the phantom is made to resemble the properties and characteristics of a tissue so that the absorbed dose value can be analyzed according to the tissue in the organ. One use of 3D printing technology is in making phantoms. Radiology phantoms must have the same characteristics as human body tissue. This research varies the thickness and infill density of the phantom to get the suitable phantom based on material density, CT number, electron density, and effective dose. The materials used are Thermoplastic Polyurethane (TPU) and Polyethylene Terephthalate Glycol (PETG) with thickness variations of 1 cm, 2 cm, 3 cm, 4 cm, and 5 cm, and infill density variations of 20%, 40%, 60%, 80% and 100 %. Based on the test parameters carried out, it was found that changes in thickness did not affect the material density, EDG, EDV, and Z eff of the sample. However, changes in thickness are proportional to the CT number and electron density values. Meanwhile, changes in infill density are proportional to changes in material density values, CT number, electron density, and EDV. However, changes in infill density do not affect the EDG and Z eff values. The values obtained for each parameter are compared with the reference organ. Samples made from TPU and PETG are suitable for lung, muscle, soft tissue, and spongy bone.
