One of these weather study data is rainfall measured from the BMKG rain observation post and TRMM satellite observations. To see the pattern of the distribution of rain that has occurred, the two weather observations can be connected as a reference for the distribution of rain. The purpose of this study was to analyze the correlation value of rainfall data between BMKG and TRMM by looking at the comparison graph and analyzing the comparison of statistical parameters. This research was conducted using daily rainfall data from 1998-2018 at four rain stations in West Java Province and taking descriptive decisions in the form of pictures and graphs in the form of daily, monthly and annual data. Based on the analysis results, the largest correlation value is in the annual cumulative with a value of 0,88-0,94, the smaller the number of days, the smaller the correlation value. The BMKG and TRMM rainfall data have relatively the same pattern, but the maximum data have differences so that it reduces the correlation value. In the Statistical Parameter analysis, it can be stated that the difference in the values ??of the statistical parameters is directly proportional to the daily cumulative, that the difference in the median and mean values ??in the BMKG and TRMM data is greater in the data with a larger cumulative. Meanwhile, for linear regression analysis, it was found that the greatest value was the cumulative 1-year value with a coefficient of determination from 0,78 - 0,89.</p> Rian Alfian, Ahmad Zakaria, Endro Prasetyo Wahono, Dyah Indriana Kusumastuti , Ahmad Herison Copyright (c) 2022 Journal of Engineering and Scientific Research http://jesr.eng.unila.ac.id/index.php/ojs/article/view/82 Wed, 15 Dec 2021 00:00:00 +0000 Effect of Added Pectin and Microcrystalline Cellulose (MCC) on Capsule Shell Quality http://jesr.eng.unila.ac.id/index.php/ojs/article/view/64 <p>The objective of this study was analyzing the effect of the added pectin and microcrystalline cellulose (mcc) on the capsule shell quality. The method used in this study was by combining the pectin and microcrystalline cellulose composition on capsule shell manufacture. The formulation used to test the capsule shells was through 1 gram, 2 gram, 3 gram of pectin; 0 gram and 1.5 gram of microcrystalline cellulose; 1 gram of glycerol; and, 1 gram of carrageenan. The experiment tests used in this study were through the organoleptic test, the capsule weight test, the moisture test, the pH test, the dissolution time test, and the capsule-length test. The result of this study showed that the recommended formulation used to manufacture the hard capsule shells was through 3 gram pectin and 1.5 gram microcrystalline cellulose. The required temperature to heat the pectin and microcrystalline cellulose was at 90<sup>o</sup>C with 2.5-hour heating time. The characteristics of the manufactured capsule shells were that it had a turbid colour and irregular shape, the surface was not smooth and the disintegration time was 9 minutes and 21 seconds.</p> <p>&nbsp;</p> <p><strong>Keywords:</strong>&nbsp;Capsule Shell, Microcrystalline Cellulose, Pectin, Variation, Testing</p> Nuke Agustin, Lia Lismeri, Edwin Azwar Copyright (c) 2022 Journal of Engineering and Scientific Research http://jesr.eng.unila.ac.id/index.php/ojs/article/view/64 Wed, 15 Dec 2021 00:00:00 +0000 Assessment of Information Technology Governance Implementation Based on COBIT Framework 5 Focus on DSS 02 Subdomain (Deliver, Service, And Support) (Case Study of Bank XXX Branch X) http://jesr.eng.unila.ac.id/index.php/ojs/article/view/91 <p>Abstract— Most of companies and organizations have used information technology to improve the effectiveness and efficiency of business performance.

We must regularly evaluate the effectiveness of PPS to ensure the system can anticipate every enemy attack; therefore, a PPS vulnerability assessment is needed. In this study, we develop a Multi-path Analysis tool for Vulnerability Assessment of PPS (MAVA) based on the Adversary Sequence Diagram (ASD) implemented in python computer code. We examined for feasibility by applying the code to a hypothetical facility (National Nuclear Research Facility - NNRF). The results of calculations compared to single-path analysis (EASI) show the advantages of MAVA, which can calculate the probability of interruption simultaneously on multi-path analysis. MAVA also predict the adversary's most vulnerable paths (MVP) with its various strategies for intrusion path. MAVA results show that multi-path calculations help analysts obtain information faster in evaluating to improve the effectiveness of PPS.</p> <p>&nbsp;</p> D Andiwijayakusuma, A Mardhi, T Setiadipura, A Purqon, Z Suud Copyright (c) 2022 Journal of Engineering and Scientific Research http://jesr.eng.unila.ac.id/index.php/ojs/article/view/92 Wed, 15 Dec 2021 00:00:00 +0000 Simulation Of Irrigation Area by Using Dependable Flow Basic Year And Basic Month http://jesr.eng.unila.ac.id/index.php/ojs/article/view/83 <p>The purpose of this study was to analyze the availability of irrigation water from the reservoir by using a dependable flow of basic month, analyze the availability of irrigation water from the reservoir by using the dependable flow of basic year and compare the calculation of the availability of irrigation water from the reservoir by using a dependable flow of basic month and the basic year, Where which is more effective.

Unfortunately, this plant is very susceptible to diseases which can reduce the quality and quantity of the crop. This paper proposes disease detection in banana plants using a thermal camera. The detection is carried out using image processing techniques with multilevel thresholding methods. The image is captured using a thermal camera, then the image is preprocessed to suit what is desired. After that, so that the position is the same as the image taken using a digital camera, the image produced by the thermal camera is carried out by an image registration process. The image processing result is compared with the ground truth image obtained from a digital camera to determine the effectiveness of the proposed method. The effectiveness of the proposed method is measured using the parameters Recall, Precision, F-measure, and Accuracy. The effectiveness of the proposed method is quite effective because it produces parameter values above 80%, namely the recall value of 86,59%, the Precision of 99,1%, the F-measure of 92%, and the accuracy of 89,78%.</p> Elka Pranita, Helmy Fitriawan, F.
