Abstract

Klasifikasi sinyal Carotid Pulse sangat penting untuk mengetahui proses terjadinya tekanan darah dalam mengalirkan darah melewati katup-katup jantung menuju ruang-ruang jantung dan paru-paru serta mendukung analisa suara jantung yang ada untuk mendeteksi murmur, mengklasifikasikan suara jantung normal dan tidak normal, serta untuk menjelaskan dinamika jantung, oleh sebab itu pada penelitian ini dilakukan beberapa pekerjaan pendahuluan pada pembuatan instrumentasi pendeteksian sinyal tekanan darah (Carotid Pulse).Pada penelitian ini dihasilkan informas Low Pass Filter Analog Orde 4 dengan frekuensi cutoff 100 Hz penguatan -3 dB terjadi di area frekuensi 120 Hz. Hasil uji Notch Filter dihasilkan tegangan output terkecil di frekuensi 50 Hz dengan besar Vout (0.14 ± 0.00) volt dengan Quality factor (Q) sebesar 6.28. Analisa sinyal Carotid Pulse dengan DFT memberikan informasi bahwa pada tekanan darah, area frekuensinya di antara 1 Hz sampai 20 Hz. Sinyal Carotid Pulse untuk siklus pertama Frekuensi tertingginya (6.81 ± 0.41) Hz dan merupakan gelombang P yang menggambarkan kenaikan Carotid Pulse secara tiba-tiba dari pemompaan darah pada ventrikel kiri menuju aorta hinggga mencapai puncak. Analisa dengan menggunakan CWT menghasilkan data keterangan waktu yang menunjukkan waktu terjadinya frekuensi tertinggi sinyal Carotid Pulse. Penelitian ini selanjutnya akan dikembangkan pada Multimodal Cardiac Analysis untuk mendapatkan informasi anatomi dan fisiologi jantung yang lebih kompleks.

Abstract

AbstrakDehidrasi merupakan kondisi kekurangan cairan tubuh karena jumlah cairan yang keluar lebih banyak daripada jumlah cairan yang masuk. Terdapat 37,3% remaja asupan cairannya kurang dari 90% kebutuhannya atau resiko dehidrasi. Dehidrasi dapat menjadi faktor resiko terjadinya obesitas pada anak dan remaja disamping asupan energi dan lemak yang berlebihan. Tujuan penelitian untuk mengetahui  perbedaan tingkat konsumsi energi, lemak dan cairan, serta status hidrasi pada mahasiswa obesitas dan non obesitas di Akademi Gizi Surabaya. Penelitian ini merupakan studi observasional analitik, dimana mencoba membanding antara kelompok obesitas dan non obesitas atau case control study. Populasi dalam penelitian seluruh mahasiswa Akademi Gizi Surabaya sebanyak 170 mahasiswa baik yang obes maupun normal, dan sampel yang diambil sebanyak 31 mahasiswa obesitas (total population) dan 31 mahasiswa non obesitas (simple random sampling). Pengambilan data asupan energi,lemak dan cairan dilakukan dengan repeated recall dan status hidrasi dilakukan dengan tes urine sedangkan uji statistik yang digunakan untuk melihat perbedaan dua kelompok dengan uji Chai Square. Hasil penelitian menunjukkan bahwa ada perbedaan tingkat konsumsi lemak, cairan dan  status hidrasi pada mahasiswa obesitas dan non obesitas di Akademi Gizi Surabaya. Mahasiswa yang obesitas memiliki tingkat konsumsi energi dengan kategori di atas normal yang lebih tinggi bandingkan mahasiswa non obesitas. Tingkat konsumsi lemak pada mahasiswa non obesitas dengan kategori defisit berat lebih tinggi (32.3%) dibandingkan kelompok obesitas (3.2%). Tingkat konsumsi cairan pada mahasiswa obesitas dengan kategori defisit berat lebih tinggi (64.5%) dibandingkan non obesitas (19.4%). Pada status hidrasi, mahasiswa obesitas banyak mengalami dehidrasi yaitu 21 responden (67.7%), dibandingkan mahasiswa non obesitas yaitu 6 responden (19.4%). Diharapkan mahasiswa terutama yang obesitas harus mendapatkan cukup informasitentang pola makannya terutama asupan cairan, karena ini akan mempengaruhi konsentrasi belajar. Perlu adanya penelitian lanjutan antara asupan cairan dan status hidrasi dengan status kesehatan pada mahasiswa.Kata kunci : Energi, Lemak, Cairan, Status Hidrasi, Obesitas AbstractDehydration is a condition of the body dehydrated because the amount of fluid comes out more than the amount of fluid intake. There are 37.3% of teens who drink less than 90% of requirements or had dehydration risk. Dehydration could be a risk of obesity besides excessive intake of energy and fat. The purpose of this study is to determine differences in the level of energy, fat and fluids consumption, and hydration status in obese and non-obese students in the Nutrition Academy of Surabaya. This was an analytical observational study which designed tried to find the differences between the two groups (obese and non obese group) or “case control study”. The population was Nutrition Academy of Surabaya, consisting 170 students, and the samples comprised 31 students of obese (total obese students) and 31 students non-obese (simple random sampling). Repeated Food Recall was  used to get energy, fat and fluid consumption. Urine test was used to know the hydration status. Statistical test used Chai Square Test .The results showed that there was a difference in the level of energy consumption, fat and fluids, and hydration status in obese and non-obese students in the Nutrition Academy of Surabaya. Students who are obese have higher percentage of energy consumption whose category more than normal compared to those who are non-obese. The percentage of fat consumption in non-obese students with severe deficiency was higher (90.9%) compared to those with obesity (9.1%). The percentage of fluid intake in obese students with severe deficiency level was higher (76.9%) than those of non-obese students (23.1%). In  hydration status, many obese students were dehydrated, consisting of 21 respondents (77.8%), compared to non-obese students which are 6 respondents (22.2%).  To get better health and students achievements, students have to get enough information about the advantages of fluid consumption., especially those who are obese. It is suggested that further research is conducted to see the relationship between fluids consumption and dehydration with health status of the students.Keywords: Fluids Consumption, Hydration Status, Obese and Non-Obese

Abstract: The railway structure includes a variety of constructions intended to supportrailroad and railway operations, one of which is a bridge. Locomotives are self-rail vehiclesthat function as rod or train carriages. Locomotives in Indonesia, especially in Java Island,have varying axle loads and axle distances, thus causing an inward force change that works onthe railway structure. The live load working on the structure of the railway bridge is a loadderived from a railway circuit whose size is determined based on the loading scheme of the1921 Load Plan (RM 1921). With RM 1921 which has been established as a rule of Bridgethrough which a series of railways passing then at a certain point on the bridge girder lengthenswill cause an inner force such as the force of moment and latitude that changes in magnitudedepending on the location of the train circuit. However, the actual condition of axle load andaxle distance is not in accordance with RM 1921. To know the magnitude of force in(maximum moment) then required an analysis calculation that is using line of influence. Fromthe calculation result between actual locomotive and RM 1921, it can be concluded that theactual maximum force of the locomotive is 30.38% less than RM 1921, therefore RM 1921 isstill sufficient to be used in the current condition Abstrak: Struktur jalan rel meliputi bermacam-macam konstruksi yang dimaksudkan untukmendukung jalan rel dan pengoperasian kereta api salah satunya adalah jembatan. Lokomotifmerupakan kendaraan rel yang dapat bergerak sendiri berfungsi sebagai penggerak rangkaiankereta atau gerbong. Lokomotif di Indonesia khususnya di Pulau Jawa mempunyai bebangandar dan jarak gandar yang berbeda-beda, sehingga hal ini mengakibatkan terjadinyaperubahan gaya dalam yang bekerja pada struktur jalan rel kereta api. Beban hidup yangbekerja pada struktur atas jembatan kereta api adalah beban yang berasal dari rangkaian keretaapi yang besarnya ditentukan berdasarkan skema pembebanan Rencana Muatan 1921 (RM1921). Dengan RM 1921 yang sudah ditetapkan sebagai peraturan Jembatan yang dilalui olehrangkaian kereta api yang melintas maka pada suatu titik tertentu pada jembatan gelagarmemanjang akan menimbulkan gaya dalam seperti gaya momen dan lintang yang berubahbesarnya tergantung dari letak rangkaian kereta api. Akan tetapi, kondisi aktual beban gandardan jarak gandar tidak sesuai dengan RM 1921. Untuk mengetahui besarnya gaya dalam(momen maksimum) maka diperlukan suatu perhitungan analisis yaitu menggunakan garispengaruh. Dari hasil perhitungan antara lokomotif aktual dan RM 1921 diperoleh kesimpulangaya dalam (momen) maksimum lokomotif aktual lebih kecil 30,38% dari pada RM 1921, olehkarena itu RM 1921 masih memadai untuk dipakai pada kondisi saat ini.

Abstract

TThe prevalence of dyslipidemia in Indonesia continues to increase. Anredera cordifolia and Curcuma xanthorrhiza are empirically used in the community to overcome dyslipidemia disorders. Flavonoids as the main compounds in A. cordifolia and curcumin in C. xanthorrhiza have potential as antioxidant activity. This study aims to determine the in vitro mechanism of A. cordifolia and C. xanthorrhiza to reduce cholesterol associated with antioxidant activity. The testing was carried out on a combination of ethanol extracts of A. cordifolia leaves with C. xanthorrhiza rhizomes (1:1) and their single extract. The antioxidant activity test was conducted using DPPH method by making serial dilution of samples and ascorbic acid with adding DPPH. The inhibitory activity of HMG CoA and lipase enzymes was carried out enzymatically using ELISA as well as simvastatin as the comparison. The results showed that the highest antioxidant activity is in C. xanthorrhiza extract samples IC50 16.21 ± 1.74 µg/mL, but was less potential compared to ascorbic acid IC50 7,63±0,85 µg/mL. The most potential inhibition of HMG CoA and lipase is in C. xanthorrhiza samples IC50 8.35 ± 0.02 and 22.35 ± 1.26 µg/mL. The combination of A. cordifolia and C. xanthorrhiza (1: 1) is better than A. cordifolia extract but lower than C. xanthorrhiza extract in antioxidant activity as well as the inhibition of HMG CoA reductase and lipase. The result showed a correlation that the higher antioxidant activity, the higher inhibitory of HMG CoA reductase and lipase respectively.

Abstract

Pests plague farmers both during planting and after harvest. One of the pests that most often causes crops to fail during harvest time is rats. These pests usually attack communities of tens to thousands of people, causing a lot of losses. Since rat pests attack close to harvest, farmers usually drive rats out of the fields. This research method uses the R&D method. This research aims to assist farmers in repelling rat pests to get good quality rice. The test that will be used is a partial test. Where, partial tests that will be carried out on sensor parts are sensor movement tests, LoRa data transmission tests and LoRa distance measurement tests. The LoRa-based rat repellent system uses a combination of sensors and ultrasonic frequency transmitters to detect and repel rats. With LoRa (Long Range) technology, the system can send and receive data remotely with little power, which enables real-time monitoring and control of devices over a wireless network. Test results show that the system can function optimally under various environmental conditions, has a wide communication range, and responds quickly to pests. This shows that the integration of LoRa in the rat repellent system can improve pest control more efficiently and environmentally friendly than conventional methods.

Abstract

WHO recommends Early Initiation of Breastfeeding (EIBF) during the first hour of life, maintaining exclusive breastfeeding for up to 6 months postpartum, and continuing breastfeeding after this period in addition to healthy foods suitable for infants up to 2 years of age or more. This form of feeding is considered effective in ensuring the health and survival of newborns worldwide. Early Initiation of Breastfeeding (EIBF) will also greatly assist in the sustainability of exclusive breastfeeding (breast milk only) and the duration of breastfeeding. The percentage of newborns who received EIBF in Central Java Province in 2023 was 87.7%, an increase compared to the achievement in 2022 of 85.9%. Meanwhile, the percentage of exclusive breastfeeding for infants aged 0-6 months in Central Java in 2023 was 64.3%, decreasing when compared to the percentage of exclusive breastfeeding in 2022, which was 71.4%. The purpose of the study was to answer the relationship between Early Initiation of Breastfeeding (EIBF) and Exclusive Breastfeeding. The analysis involved Early Initiation of Breastfeeding (EIBF) as an independent variable, and Exclusive Breastfeeding as a dependent variable. The relationship analysis was carried out using a scatter plot diagram. There are 5 regencies or cities that have exclusive breastfeeding coverage above the target of 80%, namely Klaten Regency, Jepara Regency, Purworejo Regency, Semarang City and Rembang Regency. Meanwhile, the lowest exclusive breastfeeding coverage was achieved by Semarang Regency (25.54%), with EIBF coverage (94.82%). There is a linear and positive relationship between Early Initiation of Breastfeeding (EIBF) and exclusive breastfeeding. It is necessary to examine other variables that contribute to exclusive breastfeeding to increase the coverage of exclusive breastfeeding in regencies or cities that have not met the target.
