Authors: Huda Nurul , Prayogi Sukmono Yogi , Ahmad Muna Adilah , Dewi Alfa Yuliana
Published: December 2022

Penyakit malaria merupakan infeksi penyakit yang ditularkan oleh nyamuk baik dari manusia ataupun hewan lain melalui protozoa parasit yang biasa disebut plasmodium. Malaria bisa berakibat fatal  jika terlambat dideteksi dikarenakan dapat mengakibatkan anemia akut,  gagal ginjal, hingga berujung kematian. Infeksi malaria sebenarnya bisa dideteksi dini menggunakan sampel sel darah merah, dikarenakan sel darah merah yang terinfeksi parasit akan tampak pola atau bercak. Dalam penelitian ini menggunakan data set publik berupa gambar sel darah merah yang terinfeksi protozoa parasit dan tidak terinfeksi. Beberapa peneliti sudah melakukan penelitian untuk mengklasifikasikan penyakit malaria dari sampel sel darah merah. Pada umumnya peneliti sebelumnya menggunakan metode image processing dengan mengubah gambar menjadi negatif untuk kemudian di klasifikasikan menggunakan metode klasifikasi tertentu. Di dalam penelitian ini penulis mencoba mengembangkan metode lain yaitu dengan melakukan pre-prosessing terlebih dahulu terhadap data set yang ada yaitu dengan mengubah ukuran gambar menjadi ukuran PIXEL 100x100, untuk kemudian dilakukan image augmentation untuk memperbanyak data set sehingga kemungkinan akurasi naik menjadi lebih tinggi. Proses selanjutnya yaitu mengubah dimensi gambar yang semula berdimensi tiga menjadi 1 dimensi dengan proses fitur reduksi menggunakan PCA (Principle Component Analysis) hasil dari fitur reduksi tersebut selanjutnya diklasifikasikan menggunakan metode Convolutional Neural Network (CNN). Hasil dari penelitian menunjukkan peningkatan akurasi yang lebih baik menjadi 98,30% dengan menggunakan metode tersebut.Kata kunci: image processing, CNN Classifier, Malaria, image augmentation, PCA

Published: December 2022

Objective: In this study, we aimed to compare the postoperative outcomes and urinary retention rate of urinary catheters removed after 6, 12, and 24 hours in cesarean section (CS) patients.
Materials and Methods: Pregnant women who had undergone term elective CS for previous CS indication under spinal anesthesia were included in this prospective study. Patients were divided into three groups in a 1:1:1 ratio and the patient’s urinary catheter was removed after 6, 12, and 24 hours. The residual urine amount was calculated with ultrasonography. In addition, the time until ambulation, recatheterization rate, urinary tract infection (UTI) symptoms, and the duration of hospitalization were recorded.
Results: The urinary retention rate (13.9 %) was significantly higher in the group whose catheter was removed after 6 hours. The time to the first ambulation was affected by the duration of the catheter and was significantly higher in the group whose catheter was removed after 24 hours (p=0.038). Additionally, dysuria and UTI were seen significantly higher in the group whose catheter was removed after 24 hours. However, the length of hospital stay was similar between the three groups.
Conclusion: Considering the benefit-harm balance, removal of the urinary catheter at 12 hours after CS could be suggested. However, the duration of urinary catheter removal should be individualized.

In this study, the use of biodiesel from nyamplung oil (Calophyllum Inophyllum) was studied through a transesterification reaction using a heterogeneous catalyst of CaO from limestone originating from Pamekasan, Madura. The composition ratio used between nyamplung oil and methanol in the transesterification reaction was 1:12 (mol/mol) with the addition of 4% CaO catalyst. The biodiesel that is formed is then tested for its performance and emission characteristics in diesel engines with various fuel mixtures between pure diesel and biodiesel (B-10, B-20, B-30, B-40, B-100 and S-100). The test results for biodiesel blends with the highest power produced from B-10, B-20, B-30 and B-100 fuels were 0.26 kW each at a load of 250 watts. While at a load of 500 watts, the highest power is obtained from the B-40 fuel, which is 0.58 kW. The results of performance testing using S-100 fuel obtained the highest power values ​​of 0.27 and 0.58 kW, respectively, with a load of 250 and 500 watts. Performance testing for biodiesel blends, the highest torque value was obtained when using B-10, B-20, B-30 and B-100 fuels, which were 1.65 N.m each with a load of 250 watts. While at a load of 500 watts, the highest torque is obtained on B-40 fuel, which is 3.69 N.m. The fuel S-100 produces torque of 1.71 and 3.69 N.m, respectively, with a load of 250 and 500 watts. Emission gases characteristics of carbon monoxide (CO), nitrogen monoxide (NO) and nitrogen oxides (NOx) showed the lowest concentrations obtained in B-100 fuel were 387 ppm, 92 ppm and 96 ppm, respectively. Meanwhile, the highest concentrations of CO, NO and NOx emissions were produced from pure diesel fuel (S-100), namely 574 ppm, 126 ppm and 132 ppm, respectively.

Beluntas (Pluchea Indica L.) which commonly used as astringent and antipyretic has a high potential for the feedstock of essential oil production. The objective of this work is to optimize solvent-free microwave extraction (SFME) of Beluntas leaves by using response surface methodology (RSM). Box-Behnken Design with the variations of extraction time (60-120 min), feed/distiller ratio (0.06-0.1 g/ml), and heating power (150-450 W) was utilized to optimize essential oil yield. The feed/distiller ratio factor had the highest significant effect on the essential oil yield (P<0.05). Essential oil yield increased as the increase of oil heating power and time extraction, and vice versa. On the other hand, the increase in the feed/distiller ratio gave a negative impact on the essential oil yield. The maximum essential oil yield using SFME method of 0.2728 b/b% was obtained for the optimized condition of extraction time of 90 min, microwave heating power of 450 W, and feed/distiller ratio of 0.06.

The country's economy is supported by banking institutions. This is because the benefits of credit are greater compared to other bank businesses such as savings fund deposit services fees, interbank delivery service fees and so on. Internal factors that affect lending include CAR, ROA, NPL, LDR and BOPO. This research was conducted with the aim of simultaneously testing CAR, ROA, NPL, LDR and BOPO on bank credit distribution. The research sample is the bank with the largest number of assets in Indonesia. Data were obtained from the financial statements of the Persero's commercial banks from 2013 to 2017, using the panel data regression data analysis method. The results of hypothesis testing on CAR have a positive influence on lending, ROA also has a positive effect on lending, NPL has a negative effect, LDR has a positive effect, BOPO has a negative effect, whereas if tested simultaneously, CAR, LDR, NPL, LDR and BOPO has a positive effect on lending. With regard to the above conclusions, bank management should be able to take into account the trend of financial ratios for several years, before determining the lending policy
