Published: July 2020

Abstract
The quality of agricultural land is an important factor for corn farmers in Madura. Control of maize plants is affected by the use of pesticides when viewed from a positive perspective can help humans in terms of eradicating pests that damage agricultural land. But on the other hand, pesticides also have a negative impact on humans and the surrounding environment, namely the breakdown of the food chain. To overcome this problem, biopesticides can be used in the form of bacteria that can kill plant pest organisms (OPT). Bacillus thuringiensis is one of the bacteria that can produce protein crystals that are insect killers (insecticides) when undergoing a sporulation process. By studying this identification, it is expected that farmers can analyZe the use of pesticides and replace them with bio-pesticides that are more environmentally friendly. In this study, an image processing approach was used to identify the presence of biopesticide bacteria. At the pre-processing stage, the stages of a culture of bacterial colonies were carried out on Blood Agar Plate media, followed by repairs to the results of image morphology. Fuzzy Clustering level set is one of the methods used in the image segmentation process. The results of form extraction are then used in the training process to determine the type of bacteria in the sample. This method makes identification of agricultural land easier, faster and costs less. The result is that in processing 100 training data and 25 data testing using Bacilli bacteria with 9 bacterial morphological attributes and 2 identification classes the accuracy value of the Random Forest decision tree was 91%.

Abstract
Web crawlers are programs that are used by search engines to collect necessary information from the internet automatically according to the rules set by the user. With so much information about sports news on the internet, it takes web crawlers with incredible speed in the process of crawling. There are several previous studies that discussed the process of extracting information in a web document that needs to be considered both in terms of both aspects, including in terms of the structure of the web page and the length of time needed. Therefore, in this research the web crawler application was developed by applying a multi-thread approach. This multi-thread approach to research is used to produce web crawlers that are faster in the process of crawling sports news by involving news sources more than one address at a time. In addition to the multi-thread approach, adjusting the structure of the website pages is also done to ensure the information to be extracted by web crawling. From the results of the multi-thread implementation test on the crawling process, this study has been able to increase speed compared to the single-thread method of 122.95 seconds. But the results of web update detection, have resulted in a speed that decreased by 6.27 seconds in the crawling process with unequal data and the speed on the crawling process has also decreased by 24.76 seconds on server 1 and by 23.92 seconds on server 2.

Authors: Kuswanto Dwi 
Published: July 2020

Abstract
Text File Services is still an option for sending a message, the visible difference between Text File Services and other services besides the file size of sending messages is the security level. In Instant Messenger there are features to secure conversations with various Cryptograph methods, while Text File Services does not have that feature. Therefore made Text File Services with additional features Cryptograph. Cryptograph method used is the RSA algorithm. The RSA algorithm makes the plaintext increase in the number of characters, so the Compression feature needs to be added to suppress the increase in the number of characters. Shannon Fano is a Compression symbol wise algorithm where each character that is compressed is converted into a new binary code. This compression is intended to reduce the number of Encryption result characters. The results of this study obtained information that the RSA and Shannon Fano methods can be implemented in the text file service, with the longer key being used the longer the process of decryption of messages with the average value of the avalanche effect ciphertext and the result of Compression is relatively the same. The key length used for the possibility of Brute Force is positively correlated with an average Test Compression Ratio of 1.41 and space-saving of 29.37%.

Authors: Lufika R D 
Published: July 2020

Abstract
The global supply chain allows companies to distribute their product all around the globe. The companies have to prepare themselves with an integrated system that is involving the possibility to deliver the product to the farthest area within their regional target. However, the limited due date of products generates the distribution and inventory problem that is complex and challenging to solve. One of the methods to solve the distribution problem of products with the due date is to use the system thinking approach to identify the root of the problem. The Economic Order Quantity (EOQ) method is the most reliable method to discover the most cost-effective strategy, especially for products with the limited due date. The company for this case study is PT Y. The main problem of the company is stock out. The result shows the root of the problem in this company is the unstable demand from the customer, storage management, and distribution management. There are similarities between the three root problems. The due date and quantity are the factors that control the three root problems. The result also shows that the EOQ Model that is taking the due date into account is more expensive than regular EOQ model.

AbstractFluid flow performances were performed as preliminary research on double pipe heat exchanger with longitudinally corrugated. In this experiment, the annulus tube is geometrically design and form of alternating groove. This experiment using longitudinal grooved pipe as inner tube of double pipe heat exchanger. The objective of this investigation is to determine the pressure loss along the pipe as a time series function. The fluid mechanics analysis of in this paper also provide pressure drop of system and presenting pressure signal. The longitudinal grooves were incised on outer surface of tube side with number of longitudinal grooves of 2. 0.3 mm high and 1 mm width grooves were kept constant. The tube made of aluminium with outer diameter is 20 mm. The shell is made of acrylic which has 26 mm in internal diameter. The hot fluid flows in tube space and the cold fluid flows in the annulus space of double pipe heat exchanger. Counter flow scheme use in this experiment with water as working fluid. The volume flowrate of cold fluid was varied from 11 lpm up to 15 lpm which is equal to Reynold Number (Re) range around 31981 up to 43610. The other hand, the volume flowrate of hot fluid remains constant at 15 lpm which is equal to (Re) around 30904. Pressure data was recorded using differential pressure tranducers and digitalize using data logger. The corresponding comparison of the pressure drops revealed the corrugated double-pipe heat exchangers had 5.2 % larger pressure drop. The grooved-double pipe heat exchanger has more disadvantage on fluid performance since the thin corrugated area are slightly increased which essentially correlation on larger pressure drop.
