Authors: Sarimun Putra Muhammad Hafidz , Wibisana Hendrata
Published: November 2023

Salah satu permasalahan yang sering terjadi pada kota besar di Indonesia yaitu kepadatan lalu lintas. Pertumbuhan ekonomi dan kepemilikan kendaraan menjadi salah satu penyebab permasalahan tersebut terjadi. Salah satu ruas jalan yang sering terjadi kepadatan yaitu pada ruas jalan Diponegoro. Melihat kondisi lalu lintas pada ruas jalan Diponegoro, maka diperlukan penelitian untuk mengetahui informasi mengenai karakteristik arus lalu lintas. Karakteristik lalu lintas merupakan hubungan hubungan antara tiga parameter utama lalu lintas yaitu volume, kecepatan, dan kepadatan. Salah satu pendekatan model matematis dan grafis yang digunakan untuk mengetahui karakteristik arus lalu lintas tersebut yaitu model underwood. Dari hasil penelitian dan analisis menggunakan model Underwood pada ruas Jalan Diponegoro didapatkan nilai r2 terbesarnya yaitu pada Segmen 1 Jalur 1 (Arah Kebun Binatang Surabaya) pada hari Senin sebesar 0.8925. Nilai masing-masing variabel pada segmen ini yaitu, Qmaks sebesar 2509.18 smp/jam, Dm sebesar 145.54 smp/km, Vf sebesar 46.86 km/jam, dan Vm sebesar 17.24 km/jam. Dikarenakan nilai r2 terbesar mendekati nilai +1 sehingga dapat dikatakan bahwa nilai variabel yang dihasilkan dari model Underwood mendekati kondisi lapangan sebenarnya. Maka, pemilihan model Underwood untuk ruas Jalan Diponegoro adalah tepat. Indeks tingkat pelayanan jalan pada ruas Jalan Diponegoro termasuk dalam kategori pada tingkat pelayanan C (Arus Stabil).

Authors: Haryanto Sugeng , Sabban Helda
Published: November 2023

The Caisim vegetable crop (Brassica chinensis) is a commodity that has commercial value and is a favorite commodity for some people in Indonesia. The demand for Caisim crop is expected to increase along with population growth with increased purchasing power. Moreover, Caisim crops are easily available in the market. The study determines the effect of treatments of foliar organic fertilizer application time on growth rate and production rate of Caisim (Brassica juncea L) crops. The research carries out in Gambesi, South Ternate from July to September 2020. Caisim crops in the beds are treated with morning fertilizing using foliar fertilizer. The research uses a randomized block design of 5 treatments and 3 replications. The 15 treatment units, namely P0 = without fertilization (control), P1 = application time at 6.00 - 7.00 WIT, P2 = application time at 7.00 - 8.00 WIT, P3 = application time at 8.00 - 9.00 WIT, and P4 = application time at 9.00 - 10.00 WIT. All treatments (P1, P2, P3, and P4) use the same dose of 2 cc/liter of water. The results indicate that the treatment P1 (6.00 - 7.00 WIT) has an excellent effect on fertilizer application times because it has a significant effect on crop height, the number of leaves, leaf area, and fresh weight compared to treatment P0, P2, P3, and P4.

Published: November 2023

The National Amil Zakat Agency (BAZNAS) of the Banjar Regency, is the regional Zakat Management Agency of the Banjar Regency. BAZNAS Banjar Regency distributes the required alms according to the target to mustahik that is under the criteria or following the provisions of the Shari'a. However, BAZNAS often experiences difficulties in determining mustahik (people who are entitled to receive zakat) due to limited distribution funds and excessive data on Fakir and miskin people who are the main priority. The existence of a system that can determine two groups of recipients of the Fakir and miskin zakat based on data from the underprivileged population can help the distribution of zakat to these 2 groups. In this case, using the Naive Bayes method is very suitable in the classification of the BAZNAS mustahik determination so that it can be used to determine the prospective recipient of zakat. Based on the results of tests conducted on the NaÃ¯ve Bayes classification with the Confusion Matrix calculation, the accuracy value reached 92.30%.

Published: November 2023

This research is a descriptive exploratory studyÂ aiming at analyzing the abundance index and diversity index of soil macrofauna in organic and conventional vegetable fields.Â Â The research method used is an entrapmentÂ (Pitfall traps)Â method where traps are installed in a land with 10mx25m of size and results in 10 plots.Â Each plot has 5 points determined diagonally to place the pitfall traps; therefore, the total sample points are 50 samples per observation location.Â Identification of macrofauna trapped in the pitfall trap uses a microscope.Â Based on the results of diversity analysis, soil macrofauna in organic fieldsÂ hasÂ H'2.6546Â with an abundance ofÂ 2242Â individuals, whereas the conventional fields haveÂ H'1.6775Â with an abundance ofÂ 1507Â individuals. In terms of dominance index,Â the conventional fields have a higher evenness of 0225 with a low value of 0229, while the organic fields have a low dominance index of 0077Â yet a higher evenness value of 0344.Â It can be concluded that the diversity of soil macrofauna in the organic vegetable fields in Ternate city has a higher diversity value because the fields have abundant and more even availability of soil macrofauna so that there are no dominant species found. On the other hand, the conventional vegetable fields have low abundance so that the diversity of soil macrofauna in the fields is low due to one dominant species.Â The results of the analysis in the two fields indicate that the similarity index is 0.803, which means that the similarity value of the macrofauna species in the two fields is close to the index value.Â An index value is 0 if there are no similar species in both fields and the value is 1 when both fields have the same species composition.Â However, the diversity of soil macrofauna in the two different fields has an abundance of soil macrofauna so that it can increase soil fertility and maintain the stability of soil macrofauna and its function in a sustainable agricultural system.

The aim of this study was to test the leisure boredom perceptions and predictive power for motivations for participation in physical activity and presenteeism perceptions and analyze the effects among university students. Additionally, a secondary aim was to reveal whether leisure boredom perceptions, physical activity motivation and presenteeism differed according to some variables or not. In line with these aims, a total of 517 students attending different universities in Türkiye and volunteering to participate in the research completed the Leisure Boredom Scale (LBS), Motivation Scale for Participation in Physical Activity (MSPPA) and Presenteeism Scale for Adults (PSA). The data underwent correlation, regression, MANOVA and ANOVA. According to regression analysis, the LBS boredom subscale predicted the PSA work completion and avoiding distraction subscales; while it significantly predicted the MSPPA subscales of “individual reasons” and “lack of reasons”. Additionally, the LBS “dissatisfaction” subscale appeared to significantly predict the PSA “work completion” and MSPPA “individual reasons”, “environmental reasons” and “lack of reasons” subscales. The research findings identified significant differences according to gender, membership status and physical activity participation variables. In conclusion, the physical activity motivation and presenteeism of university students were identified to be associated with perceived boredom during leisure, and it is understood leisure perceptions positively affect important areas of life (like health and education).

Published: November 2023

Understanding the relationship between anaerobic performance and time of useful consciousness (TUC) is important for individuals engaged in activities at high altitudes such as climbers, pilots, or astronauts. The aim of this research is to investigate the relationship between anaerobic capacity and TUC determined in a low-altitude chamber (LAC), in terms of performance and heart rate variability (HRV), in healthy males. Thirty male participants were included in the study as volunteers (mean age: 23.2±0.8 years; height: 180.6±6.0 cm; weight: 77.0±8.2 kg). In the scope of the research, participants were exposed to oxygen in a LAC at an atmospheric level of 25.000 feet after body measurements were taken on the first day, and TUC was determined. Anaerobic capacities of the participants were determined the following day using the Wingate Anaerobic test (WAnT). HRV was recorded before, during, and after both tests. According to the findings of our research, the parameter changes of Mean-RR, SDNN, and frequency domain parameters HFnu were significant for both WAnT and LAC in terms of TUC in the pre-test, during the test, and post-test periods. RMSSD change was significant for LAC, while LFnu change was significant for WAnT. In intra-group comparisons, there was a significant difference between pre-test and during the test for WAnT, but no significant difference between during the test and post-test. For LAC, there was a significant difference between pre-test and during the test, as well as between during the test and post-test. In terms of the relationship between anaerobic capacity and time to achieve TUC, TUC showed a non-significant negative correlation with relative peak power (r=-0.03; p=0.86), and non-significant positive correlations with total peak power (r=0.19; p=0.31) and total mean power (r=0.23; p=0.23). The most striking result of this research is the lack of significant relationship between TUC duration and anaerobic performance of the participants. Additionally, in terms of TUC, recovery was significant after TUC in LAC, while no recovery was observed after WAnT. According to the results of this research, anaerobic exercises are not a priority in terms of performance and HRV change to increase TUC. Anaerobic performance may not be the primary criterion for personnel selection for high altitude missions.

Atrial fibrillation and chronic renal failure are common diseases in the population with similar risk factors. Both conditions are independent riskfactors for the development of thromboembolic complications. There is compelling evidence to support the benefits of anticoagulant therapy for atrial fibrillation in the general population, but in patients with advanced chronic renal failure, the use of anticoagulants may be limited. A number of studies have shown conflicting results, and this topic is of interest for further discussion and a comprehensive analysis of the existing data.
Chronic kidney disease in patients with chronic heart failure infected with human immunodeficiency virus
Authors: Goryacheva O. G.
Published: November 2023

Chronic kidney disease (CKD) is the most common manifestation of target organ damage in chronic heart failure (CHF). The aim of the study was to determine the risk factors associated with the course of CKD in patients with CHF infected with the human immunodeficiency virus (HIV). According to the results obtained, the prevalence of CKD among HIV-infected patients with CHF is 58.82%, which is 4 times more common than in patients with HIV infection without CHF. The dependence of glomerular filtration rate (GFR) on three main factors that reflect damage to the heart muscle – blood plasma NT-proBNP concentration, left ventricular ejection fraction (LVEF%) and left ventricular myocardial mass index (LVMI) was proved, which together, being included in the regression model, determine 42.2% of the variance of GFR values and are decisive in the development of CKD in patients with CHF on the background of HIV infection. The concentration of NT-proBNP in the blood plasma of patients with CHF equal to or greater than 683.65 pg/ml can be considered as a diagnostic criterion for the development of CKD in HIV-infected people with a sensitivity of the method of 75.0% and a specificity of 75.4%, respectively. In addition, risk factors for the development of CKD in patients with CHF and HIV infection are smoking, alcohol and drug use, a history of chronic and acute forms of coronary artery disease, atrial fibrillation, ventricular arrhythmias, diabetes mellitus, chronic viral hepatitis C, anemia and thrombocytopenia. Patients with CHF and CKD have a more rigid arterial wall – there is a significant excess of the stiffness indices of the aorta and peripheral arteries. Long-term use of antiplatelet agents, NRTIs, NNRTIs, and protease PIs may aggravate the course of CHF in HIV-infected people with CKD manifestations.

Infusion therapy is an important component of many diseases treatment – and one of the main methods of intensive care for intensive care patients. Active infusion therapy using different infusion media, large volumes and high rates of intravenous fluid is especially relevant in critical patients, the most severe of which remains patients with septic shock. For more than two centuries of clinical use, infusion therapy has gone through a long evolutionary path and has become more effective and safer. However, like any drug, infusion therapy (in general and specific infusion media) has a number of side effects, especially when used excessively. Therefore, in recent years, the use of infusion therapy is considered as the appointment of any drug, taking into account indications, contraindications, methods of administration, dosing, duration, deescalation. This made it possible to identify the main stages of infusion therapy of critical conditions and shock: intensive infusion therapy (rapid administration of a large fluid volume), optimization of infusion therapy (reduction of the rate and volume of infusion), stabilization of the patient and minimization of infusion, de-resuscitation – removal of excess fluid from the body. With the development of clinical pathophysiology, the basic concepts of maintaining fluid homeostasis of the body in normal and critical conditions were revised, and the negative effects of infusion therapy at all stages of its use were studied. Therefore, in the intensive care of shock, the main clinical questions are: when to start fluid therapy, when to stop active fluid therapy, when to start fluid removal from the body, and when to stop fluid de-resuscitation. Thus, in order to implement the principle of personalized treatment, it is important to determine not only the «tolerance» of infusion therapy, but also the «sensitivity» to the infusion of a particular patient – the ability to maintain hemodynamics without the risk of fluid overload. Evaluation of routine clinical, instrumental and laboratory indicators of the state of macro- and microcirculation does not provide an opportunity to accurately answer these questions. Modern sonographic methods for monitoring central and peripheral cardiohemodynamics, ‘venous excess’ using Doppler and extended focus echocardiography allow us to assess the ‘tolerance of infusion therapy’. The implementation of this new direction will increase the efficiency and safety of infusion therapy and improve the outcomes of the critically ill patients’ treatment.

Objective. To improve the results of treatment of comorbid patients with acute arterial ischemia by substantiating the optimal type of spinal anesthesia for surgical intervention on the affected limb.Materials and methods. The study involved 70 patients who were treated in the Department of Vascular Surgery of Clinical Hospital of ‘Russian Railways-Medicine Co.’ in Barnaul. The patients were divided into two groups: group 1 – patients operated under conditions of bilateral (bilateral) spinal anesthesia, group 2 – patients operated under conditions of monolateral (unilateral) spinal anesthesia. All patients underwent an assessment of the level of spinal block on the Bromage scale, monitoring of central hemodynamics using a MARG-10–01 rheograph, postoperative assessment of myocardial ischemia on the ECG, acute kidney damage to control diuresis.Results. In the 2nd group, there was a sufficient sensory and motor block to perform surgery. In the intraoperative period in the group of patients who underwent unilateral blockade, the mean arterial pressure decreased by 3 mm Hg. In this regard, there was no clinically significant increase in heart rate and a decrease in the stroke index and the index of total peripheral vascular resistance. In the 1st group, the decrease in mean arterial pressure reached 20% of the original, which led to an increase in heart rate by 12% and a decrease in stroke index by 11%.Conclusions. During the perioperative period, the indicators of central hemodynamics in the group 2 were more stable compared to the group 1, they did not need the use of vasopressor drugs and crystalloids. And in the early postoperative period, patients who underwent unilateral anesthesia did not show signs of acute kidney injury. Monolateral spinal anesthesia, compared with conventional spinal anesthesia, provides more stable hemodynamics in elderly patients with acute arterial ischemia.

A system using Internet of Things (IoT) technology has been developed to assist farmers in efficiently feeding their pet ducks. This system based on the Internet Of Things (IoT) method, involves various components such as loadcell and ultrasonic sensors, servo motors, a real-time clock, LCD display, power supply, and the NodeMCU ESP8266 microcontroller. The feeding process starts by filling the feed into a container hopper. The ultrasonic sensor detects the feed level and sends this information to the Blynk application. The application then opens servo motor 1 to drop the feed into a small container with a loadcell. The loadcell sensor measures the weight of the feed, and then servo motor 1 closes and servo motor 2 opens until the feed runs out, at which point servo motor 2 closes. The system continuously repeats this process and sends notifications to the Blynk application when the hopper is empty. Overall, this system helps to streamline the feeding process for pet ducks and improve efficiency for farmers.

Hal ini dapat menguntungkan pengguna karena meminimalkan penggunaan air, biaya listrik untuk pompa air dan dapat memantau penggunaan air. Maka dari itu pengontrolan level air pada rumah tangga ini dapat dilakukan suatu penelitian agar keuntungan yang di dapat menjadi optimal yaitu dengan membuat mini plant sistem kendali untuk mengatur level air yang dapat di monitoring melalui software MATLAB sehingga dapat ditampilkan dalam bentuk grafik PI yang memperlihatkan respon sistem dari kendali tersebut. Pada mini plant ini menggunakan mikrokontroller Arduino Uno, sensor ultrasonik HC-SR04 sebagai pembacaan level air, driver L298N, pompa DC, serta LCD 16x2 untuk menampilkan set point dan level air secara real time. Pada penelitian ini menggunakan metode Ziegler Nichols dan tuning manual untuk menentukan parameter Kp dan Ki. Pada metode Ziegler Nichols didapatkan nilai Kp = 1,15 dan Ki = 0,01. pada metode tuning manual didapatkan nilai Kp = 1,16 dan Ki = 0,01. Metode Ziegler Nichols dan tuning manual menghasilkan error steady state yang sama yaitu 2,1%. Metode Ziegler Nichols mempunyai keunggulan dalam delay time (Td) = 41,44 s, rise time (Tr) = 77,35 s, peak time (Tp) = 0 s, maximum overshoot (Mp) = 0%, dan settling time (Ts) = 85,94 s yang lebih cepat daripada metode tuning manual.

Pada Kontes Robot Sepak Bola Indonesia - Beroda (KRSBI-B), robot sepak bola beroda ini bertugas untuk mengoper dan menendang bola selama perlombaan berlangsung. Dengan adanya penendang, robot dapat menendang maupun mengoper bola. Pada sistem penendang ini menggunakan solenoid untuk menghasilkan energi magnetik yang digunakan untuk menarik lengan penendang robot. Energi dari sistem penendang robot sepak bola beroda ini diperoleh dari sebuah kapasitor 4700µF dengan tegangan 450V. Karena robot hanya menggunakan tegangan baterai sebesar 15V, maka diperlukan sebuah konverter untuk menaikkan tegangan menjadi 400V agar dapat mengisi kapasitor. Pada penelitian ini konverter yang akan digunakan yaitu konverter flyback tipe boost. Digunakan konverter flyback karena antara input dan output terdapat isolasi galvanik yang menunjukkan bahwa topologi konverter flyback merupakan topologi terisolasi catu dayanya. Untuk membuat output tegangan pada konverter flyback agar stabil sesuai dengan set point yang ditentukan digunakan kontrol PID. Hasil dari pengujian pada flyback converter diterapkan kontrol PID dengan masing - masing parameter Kp=60, Ki = 1,83 dan Kd = 491,25. Dengan parameter tersebut sistem dapat menuju kondisi stabil pada detik ke 8.5.

Indeks Massa Tubuh (BMI) adalah sebuah parameter yang digunakan untuk menentukan status gizi seseorang berdasarkan perbandingan antara berat badan dan tinggi badan. Saat ini, pengukuran BMI seringkali dilakukan secara manual, sehingga pengukuran BMI menjadi hal yang sulit dilakukan terutama yang belum mengetahui formula untuk menghitung nilai BMI secara tepat. Untuk mengatasi masalah ini, dibuatlah sebuah alat pengukuran BMI secara otomatis. Alat ini dirancang untuk mengukur tinggi badan dengan menggunakan kamera, serta berat badan dengan menggunakan sensor Load Cell. Proses pengolahan gambar menggunakan mikrokontroller Raspberry Pi dan bahasa pemrograman Python. Cara kerja alat ini dimulai dengan pengukuran tinggi badan dan berat badan, lalu setelah mendapatkan nilai yang dibutuhkan, alat ini akan menghitung BMI untuk memberikan informasi mengenai status kesehatan dan saran berat badan agar terhindar dari obesitas. Hasil pengujian menunjukkan tingkat akurasi sebesar 96,31% dengan tingkat eror pengukuran tinggi badan sebesar 1,67% dan berat badan sebesar 0,44%. Sedangkan untuk perhitungan BMI, tingkat eror yang dihasilkan adalah sebesar 3,69%.

Salah satu jenis unggas yang banyak dipilih oleh para peternak di Indonesia adalah ayam broiler. Umumnya, peternak ayam masih menggunakan sistem konvensional dalam memelihara ayam dengan pemakaian bohlam sebagai penghangat didalam kandang. Sedangkan suhu kandang juga perlu diperhatikan, dikarenakan hal tersebut mudah mengalami perubahan dan akan berdampak pada pertumbuhan ayam, khususnya ayam yang masih dalam masa brooding dengan kondisi fisik ayam yang masih lemah dan organ tubuh masih belum berfungsi secara semestinya, sehingga masih membutuhkan penghangat yang dapat menjaga kestabilan pada kandang di perubahan cuaca yang tiba-tiba. Sehingga alat ini dirancang menggunakan heatersebagai pengganti bohlam dengan menerapkan sistem kendali PI yang mana heater akan menyala dan menstabilkan suhu didalam kandang pada setpoint 33 derajat celcius berdasarkan pembacaan sensor DHT22 sebagai feedback dan heater akan mati ketika suhu melebihi setpoint. Pada penelitian ini didapatkan nilai parameter Kp = 20 dan Ki = 2 dengan rata-rata error stady state sebesar 0,6%. Nilai parameter yang didapatkan digunakan untuk mengendalikan keluaran pada heater. Dan suhu dapat dimonitoring melalui aplikasi blynk pada smartphone.

Pada budidaya ikan nila bioflok, aspek penting yang harus diperhatikan adalah pengadaan oksigen dalam kolam menggunakan aerator. Tujuannya adalah untuk memastikan pasokan oksigen yang cukup agar pertumbuhan ikan tidak terhambat. Permasalahan utama dalam budidaya ini adalah pemadaman listrik yang tidak teratur, menyebabkan kematian massal ikan. Untuk mengatasi hal ini, diperlukan sistem penghemat daya baterai yang mengaktifkan aerator berdasarkan konsentrasi oksigen di kolam. Sistem ini menggunakan Arduino Nano sebagai kontrol PID untuk mengendalikan kecepatan aerator berdasarkan nilai pembacaan sensor Dissolved Oxygen. Pengujian menunjukkan bahwa kontrol PID dengan nilai Kp = 10; Ki = 0.006; Kd = 0 dapat bekerja dengan baik, respon yang dihasilkan cukup baik dengan nilai Rise time = 19s dan Error Steady State = 2.83%. daya baterai/aki yang digunakan dapat dihemat hingga 30-40% saat terjadi pemadaman listrik, sehingga memungkinkan aerator beroperasi lebih lama dan menjaga kadar oksigen terlarut dalam kolam tetap stabil di angka 6 Mg/L (ppm) ketika terjadinya pemadaman listrik.
Revisiting ameloblastin; addressing the EMT-ECM axis above and beyond oral biology
Authors: Reseland Janne E. , Heyward Catherine A. , Samara Athina
Published: November 2023

Ameloblastin (AMBN) is best characterized for its role in dental enamel formation, regulating cell differentiation and mineralization, and cell matrix adhesion. However, AMBN has also been detected in mesenchymal stem cells in addition to bone, blood, and adipose tissue. Using immunofluorescence in a pilot scheme, we identified that AMBN is expressed in different parts of the gastrointestinal (GI) tract. AMBN mRNA and protein detection in several tissues along the length of the GI tract suggests a role for AMBN in the structure and tissue integrity of the extracellular matrix (ECM). Intracellular AMBN expression in subsets of cells indicates a potential alternative role in signaling processes. Of note, our previous functional AMBN promoter analyses had shown that it contains epithelial–mesenchymal transition (EMT) regulatory elements. ΑΜΒΝ is herein presented as a paradigm shift of the possible associations and the spatiotemporal regulation of the ECM regulating the EMT and vice versa, using the example of AMBN expression beyond oral biology.
