ABSTRAKPada masa pandemi COVID-19, presensi dengan kontak fisik sangat tidak disarankan karena dapat meningkatkan penularan virus. Penelitian ini bertujuan untuk merancang dan merealisasikan sistem presensi dengan fitur RFID yang contactless dan capture citra untuk menambah validasi data presensi agar tidak terjadi kecurangan. Hasil penelitian menunjukkan bahwa tag dapat teridentifikasi hingga jarak 4 cm dari permukaan casing. Pada jarak 5 cm tag tidak dapat teridentifikasi karena jarak pancar efektif gelombang radio dari sensor berkurang akibat dari ketebalan casing dan celah jarak antara sensor dengan casing. Proses presensi dapat dilakukan oleh sistem rata-rata 5,58 detik dengan waktu paling singkat 4,88 detik dan paling lama 8,44 detik. Sistem mampu melakukan ketepatan presensi sesuai event pada Google Calendar dan formulir dapat menampilkan data yang lengkap. Kesesuaian data tag dengan seseorang yang melakukan presensi dapat dicek dengan cara membandingkan foto pada formulir. Formula pada Spreadsheet dapat dimanfaatkan untuk rekapitulasi hasil data presensi. Kata kunci: Presensi, RFID, Spreadsheet, Capture Image, Jadwal ABSTRACTDuring the COVID-19 pandemic, physical presence is not recommended because it can increase the transmission of the virus. This study aims to design and realize presence system with contactless RFID features and image capture to increase attendance data validation so that fraud does not occur. The results showed that the tag can be identified up to a distance of 4 cm from the surface of the casing. At a distance of 5 cm the tag cannot be identified because the effective transmitting distance of radio waves from the sensor is reduced due to the thickness of the casing and the gap between the sensor and the casing. The attendance process that can be done by the system is an average of 5.58s with the shortest time of 4.88s and the longest being 8.44s. The system is able to perform precise attendance according to events on Google Calendar and the form can display complete data. The suitability of the tag data with someone who is present can be checked by comparing the photos on the form. The formula in the Spreadsheet can be used to recapitulate the results of attendance data.Keywords: Presence, RFID, Spreadsheet, Capture Image, Schedule

ABSTRAKDalam sebuah perusahaan manufaktur, produk yang dihasilkan selalu mengalami proses pengembangan tertentu yang mencakup pembuatan desain hingga menjadi prototype dengan tujuan untuk memenuhi kebutuhan konsumen. Salah satu mesin yang tepat dan efektif untuk pembuatan prototype adalah 3D printer. Energi listrik dibutuhkan selama proses printing, jika suplai energi listrik terhenti maka mesin 3D printer akan berhenti bekerja. Sehingga ketika suplai energi listrik tersambung kembali proses printing harus mengulang dari awal. Hal ini menyebabkan kerugian material dan waktu, semakin besar ukuran protoype yang dicetak maka akan semakin besar kerugian material dan waktunya. Oleh karena itu, mesin 3D printer memerlukan suatu kemampuan untuk menyimpan data posisi dan melanjutkan proses printing berdasarkan data tersebut. Berdasarkan pengujian akurasi penyimpanan data posisi ekstruder terhadap sumbu X, Y, Z, menggunakan AS5600 magnetic encoder didapatkan persentase error sebesar 0.004928649% pada sumbu X, 0.025628032% pada sumbu Y, 0.020581289% pada sumbu Z.Kata kunci: 3D Printer, AS5600 Magnetic Encoder, Bigtree, Cartesian, Firmware Marlin, Resume ABSTRACTIn a manufacturing company, the products produced always undergo a certain development process which includes making designs to becoming prototypes with the aim of meeting consumer needs. One of the right and effective machines for prototyping is a 3D printer. Electrical energy is needed during the printing process, if the supply of electrical energy stops, the 3D printer engine will stop working. So that when the supply of electrical energy is reconnected the printing process has to repeat from the beginning. This causes material and time losses, the larger the printed prototype size, the greater the material and time losses. Therefore, a 3D printer machine requires the ability to store position data and continue the printing process based on that data. Based on testing the accuracy of ekstruder position data storage on the X, Y, Z planes, using the AS5600 magnetic encoder, the percentage error is 0.004928649% on the X axis, 0.025628032% on the Y axis, 0.020581289% on the Z axis.Keywords: 3D Printer, AS5600 Magnetic Encoder, Bigtree, Cartesian, Marlin Firmware, Resume

Bungin Island is a very small island where population density is high, with a total population of 3,287 in a 2 kilometer-square area. The Annual Parasite Index (API) on Bungin Island in 2006 was 16,0 per thousand people. Outbreaks of malaria in Bungin Island are correlated with several controllable factors. The goal of this study is to aggressively detect and treat malaria, as well as to identify the factors that contribute to malaria outbreaks. Data was collected from the resident of Bungin Island who came to Sub-Primary Health Center Bungin Island in October 1, 2007. The data collection when outbreak malaria occurs, consisted of anamnesis, physical examination and test for type of malaria. A finger prick blood sample was collected and tested with rapid diagnostic test (RDT) for type of plasmodium. Treatment base on standard treatment for malaria from Indonesian Health Department was given to the subjects were malaria positive. The total 201 subjects was tested by RDT, in which 93 positive malaria (46,27%). Most of them were infected by Plasmodium vivax (97.85%) and only 2 subjects were infected by Plasmodium falciparum (2.15%). There were 23 subjects (24.27%) showed malaria positive without clinical symptoms. The subjects positive malaria with clinical symptoms, 8.57% were found to have spleenomegaly and 7.14% were found to have hepatomegaly. Incidence of malaria decrease siginifantly in few week after aggresive detection and appropriate treatment. A few years later, malaria incidence was disappeared. The incidence of malaria in Bungin Island was high when an outbreak occured. Aggressive detection with mass blood survey could find asymptomatic malaria in the population and appropriate treatment would decrease positive malaria until it disappeared.

Kelp can accumulate large quantities of arsenic compounds even in the absence of considerable environmental pollution. A substantial difference in toxicity between organic and inorganic arsenic compounds makes the form of arsenic relevant for the risk assessment of consuming kelp thalli and kelp-based products.The aim of the study was to develop an analytical procedure for the selective quantification of organic and inorganic arsenic in kelp thalli by inductively coupled plasma mass spectrometry and solid-phase extraction without scheduled precursors.Materials and methods. The authors studied samples of Laminaria saccharina and Laminaria japonica, spiking mixtures of chemical compounds containing arsenic in different oxidation states, and bioactive dietary supplements based on kelp thalli. Solid-phase extraction was performed using Maxi-Clean SAX cartridges. The arsenic content was determined using an Agilent 7900 inductively coupled plasma mass spectrometer.Results. Microwave-assisted extraction with deionised water ensures 91% recovery of arsenic-containing compounds from kelp thalli, and the addition of hydrogen peroxide to the extractant provides complete extraction. Solid-phase extraction with an eluent based on 3% H2O2 can extract the organic fraction from a mixture of organic and inorganic arsenic compounds without washing the inorganic fraction off the cartridge.Conclusions. The authors offer an effective analytical procedure for the selective quantification of organic and inorganic arsenic in kelp thalli and kelp-based products. This procedure allows for the isolation of arsenic-containing compounds from the organic matrix of kelp with 3% hydrogen peroxide. Solid-phase extraction with this extractant can effectively separate organic and inorganic fractions without prior neutralisation of the test solution.
