Abstract

Abstrak. Sistem isolasi seismik yang tersedia dewasa ini menggunakan teknologi canggih dan umumnya digunakan pada bangunan berlantai banyak. Penelitian ini mengkaji karakteristik isolasi bola baja yang sederhana tetapi diharapkan handal untuk bangunan rumah. Beban bangunan dimodelkan sebagai massa tunggal dan meja getar memodelkan tumpuan dasar (base). Isolasi bola dipasang di antara massa dengan meja getar. Rumah bola dibuat dua macam yaitu berbentuk tabung belah dan ½ bola. Beban siklis diaplikasikan pada meja getar dengan amplitudo 5, 10 dan 20 mm, frekuensi 151 dan 240 cpm. Friksi dalam sistem isolasi diukur. Respons massa dalam gerakan satu arah direkam pada kertas skala. Hasil penelitian menunjukkan bahwa semakin tinggi percepatan meja getar am, semakin besar persentase redaman percepatan yang dirambatkan ke massa. Dalam rentang parameter input yang diaplikasikan, untuk rumah bola berbentuk tabung belah, redaman percepatan mencapai 92% sampai dengan 99 %, sedangkan untuk rumah bola berbentuk ½ bola mencapai 35% sampai dengan 92 %. Rumah bola berbentuk tabung belah jauh lebih efektif meredam percepatan dibandingkan dengan rumah bola berbentuk ½ bola, dengan angka perbandingan respons percepatan massa 1:7 sampai 1:8. Abstract. Seismic isolation systems being available recently are sophisticated technology and commonly used to reduce multi-storey building response from seismic ground motions. The simple steel ball isolation was conducted to predict the reliability of housing structures in response of seismic ground motion due to earthquake. To develop a model, the building loads are assumed as a single mass system and a vibration table as a supporting base. The steel ball isolation was installed between the mass and the table. Two houses shapes are made, that is, a split cylinder and an half ball. Sinusoidal forces were applied on vibrating table with the amplitudes of 5, 10 and 20 and the frequencies of 151 and 240 cpm. Frictions in the isolation system were measured, while movements of mass responses based on one direction displacement were recorded on scaling papers. This research reveals that the higher the vibrating table acceleration (am), the higher the percentage of  damping spreads through the mass. In the range of the application of input parameters, the accelerations are reduced from 92% to 99 % for split cylinder ball’s house, and from 35% to 92 % for half-ball ball’s house. The split cylinder-ball house is much more effective to reduce acceleration than the half-ball house. Those ratios of mass acceleration responses are from one eighth to one seventh.

Abstract

Abstrak. Keruntuhan gedung akibat gempa masih menjadi masalah yang perlu dipecahkan. Penelitian ini mempelajari kinerja isolator seismik bola-pegas pada model struktur fleksibel satu lantai skala kecil. Massa model pada level atas dan bawah masing-masing 30 kg. Bola isolator dipasang di antara model struktur dan landasan getar. Pegas dengan konstanta 500N/m dipasang untuk memulihkan model ke posisi semula pasca getaran. Satu ujung pegas diikat pada setiap sudut bawah model dan ujung lainnya diikat pada landasan getar. Kolom dari model dengan konstanta pegas 22117 N/m, dijepit pada ujung atas dan bawah. Getaran sinusoidal diaplikasikan pada landasan getar dengan frekuensi 10.6, 15.35 dan 20.44 rad/s serta amplitudo 5, 10, 15 dan 20mm. Hasil penelitian menunjukkan bahwa respons percepatan model as, meningkat secara linier terhadap peningkatan percepatan landasan am, sedangkan rasio respons percepatan model terhadap percepatan landasan (as/am) berkurang seiring dengan peningkatan percepatan landasan. Isolator bola-pegas sangat efektif mereduksi percepatan terutama pada percepatan landasan yang relatif tinggi. Pada percepatan landasan rendah (0.05g),rasio reduksi percepatan (am-as)/am, mencapai 39% pada level atas dan 45% pada level bawah, sedangkan pada percepatan landasan lebih dari 0.2g, rasio reduksi percepatan tersebut mencapai lebih dari 80% pada kedua level.Abstract. The collapse of buildings due to the earthquake is still an issue that needs to be solved. This research studied the performance of the ball-spring seismic isolator on a reduced scale, single-story, flexible structure model. Model’s mass on each top and bottom level is 30 kgs. Ball isolator is mounted between the structure model and vibrating base. A spring constant support of 500N/m is installed to restore the model to its original position after the vibration. One end of the spring is tied to each bottom corner of the model and the other end is tied to the vibrating base. The column of the model with the spring constant of 22,117 N/m, are clamped at the lower and upper ends. Sinusoidal vibrations were applied on vibrating base with the frequencies of 10.6, 15.35 and 20.44 rad/s and the amplitudes of 5, 10, 15 and 20 mm. The results show that the model acceleration response rates (as) increase linearly to increasing the base acceleration rates (am), while the ratio of the acceleration responses model to the base acceleration (as/am) decreases with an increasing the base accelerations. Ball-spring isolators very effectively reduces acceleration especially at the level of high rates of the base acceleration. At the level of the lower base acceleration (0.05g), acceleration reduction ratios, (am - as)/am, reach 39% at the top level and 45% at the bottom level, while the base acceleration of more than 0.2g the acceleration reduction ratios reach more than 80% at the both level.

Abstract

Pemeriksaan detak jantung dan suhu tubuh merupakan parameter tanda vital yang mendasar bagi paramedis dalam menentukan kondisi fisik pasien. Pemeriksaan detak jantung dan suhu tubuh dilakukan oleh petugas medis umumnya menggunakan elektrokardiogram dan termometer. Penggunaan kedua alat ini masih memiliki kelemahan karena selalu dilakukan berulang-ulang dan membutuhkan konsentrasi untuk mendapatkan nilai yang akurat. Metode ini niscaya akan menimbulkan beberapa masalah, seperti waktu yang dibutuhkan oleh tenaga medis cukup lama dalam menentukan diagnosis, menambah beban staf medis dalam melakukan pemeriksaan, dan meningkatkan biaya yang harus dikeluarkan oleh pihak pengelola dalam menyediakan peralatan medis. Sensor yang digunakan dalam penelitian ini terdiri dari sensor AD8232 sebagai sensor detak jantung yang diubah dalam bentuk denyut per menit (bpm) dan sensor DS18b20 sebagai pendeteksi suhu tubuh dalam derajat celcius (0C). Penelitian ini bersifat fundamental dan bermanfaat dalam mengurangi beban tenaga medis, mencegah terjadinya kesalahan diagnostik terutama dalam pemeriksaan detak jantung dan suhu tubuh. Hasil dari desain yang diusulkan menunjukkan bahwa pendeteksi detak jantung dan sensor suhu tubuh bekerja dengan baik.

Abstract

The PDAM is still using an analog flow meter. For PDAM customers, information on analog flow meters is difficult to access and convert into payment amounts. With an analog reading system, the PDAM officer still records using the manual method of the customer's total water consumption data. From the problems above, we need a digital reading system that can display customer water consumption and payment data that can be accessed by customers. The reading of the volume of water consumed by PDAM customers via SMS is a device designed based on the Arduino Uno microcontroller, equipped with the ability to monitor water usage in real time using SMS media. The reading of the volume of water consumed by PDAM customers uses a water flow sensor that functions to read the flow of water that passes and provides pulse output. Arduino Uno receives pulse output from the water flow sensor which is then converted into a number that shows the number and tariff of water usage of PDAM customers. The LCD displays information on total usage, usage rates, time and date in real time. The SIM800L module sends SMS based on orders received from customers and PDAM officials. The results achieved in this study are the water flow sensor is able to read the amount of water consumption of PDAM customers with an average deviation of 0.034%. Tests show the results of payment conversions are in accordance with the PDAM payment model in Palu City.
