Integrasi Budidaya Tanaman Kangkung (Ipomea Aquatica Forsk) dan Ikan Nila Menggunakan Internet of Things
Get PDFAquaponics is an application of a sustainable agricultural system by integrating the cultivation of plants and fish at one time. Water availability in plant commodities and water is optimized in aquaponic cultivation systems. Several parameters that can determine the level of success of cultivating an aquaponic system include water pH, water temperature, TDS, and water level. The process of monitoring and controlling several important parameters in cultivation can be done conventionally, but it is less effective and efficient because the cultivator has to check and measure the parameters every time. Therefore, as time goes by, and technology becomes more sophisticated, a control and monitoring system is designed. several parameters such as water pH, water temperature, TDS, and water level based on the Internet of Things (IoT) to support the success of the aquaponics system by monitoring environmental conditions using a laptop/smartphone at that time. Based on the test results, it was found that aquaponics in an indoor environment is successful - the air conditioner has a water temperature below 250C, the water pH shows 7pH and the average nutrient in the water shows 214.5 ppm. Based on this, kale plants in the stem grow quickly while leaf growth is very stunted. At temperatures smaller than 25 0C pomfret fish only survive for 2 weeks but tilapia fish can survive and not die in these environmental conditions. The length of the tilapia fish for 6 weeks has increased by 5 cm from its original length

Website Penetration Analysis Against XSS Attacks using Payload Method
Get PDFThis research aims to analyze the effectiveness of various penetration testing methods in identifying and mitigating XSS (Cross-Site Scripting) vulnerabilities in web applications. XSS is a type of web security attack that takes advantage of weaknesses in web applications to insert malicious code into web pages displayed to users. This attack can steal user data, take over user sessions, or spread malware. This research uses a penetration testing method with a black-box approach, where the researcher does not know the construction of the system being tested. Tests were conducted on 10 random websites, including 5 open-source websites and 5 commercial websites. The test results show that the payload method used is effective in exploiting XSS vulnerabilities on some websites. Of the 10 websites tested, 6 of them were successfully exploited using different payload methods. This research highlights the importance of using open-source penetration testing tools in detecting and addressing security vulnerabilities in web applications. These tools are easy to implement, supported by extensive documentation, and have a strong community. This research also emphasizes the importance of a deep understanding of how penetration testing tools work to identify and address security vulnerabilities. To address XSS vulnerabilities, this research recommends good programming techniques such as programming language updates, use of OOP (Object-Oriented Programming), MVC (Model-View-Controller) concepts, and use of frameworks. Further research can be done to develop and test new payload methods, explore the use of other penetration testing tools, and test security vulnerabilities in other types of web applications

The research method used in writing this scientific work is by using literature study. The purpose of this writing is to find out and implement an automation system for feeding catfish to make it easier and more efficient in feeding catfish. The results obtained from this automatic tool can make it easier for humans to operate, so that it no longer needs to be powered manually. Just automatically use the feeder. In conclusion, the implementation of an automatic system using IoT and Arduino Uno has been proven to be able to streamline catfish feeding times
PENGARUH PENAMBAHAN LIMBAH KULIT PINUS TERHADAP HASIL PIROLISIS LIMBAH PLASTIK HDPE SEBAGAI BAHAN BAKAR ALTERNATIF
Get PDFWaste often becomes a problem for society. Pyrolysis is considered an effective solution to reduce waste and can produce end products that can be utilized as energy sources. This study uses HDPE plastic waste with variations in the addition of pine bark waste at 0%, 25%, 50%, and 75%, with a total mass of 500 grams and the addition of 100 grams of bentonite catalyst. The pyrolysis process is carried out for 120 minutes at a temperature of 320°C. The aim is to examine the effect of adding pine bark on the pyrolysis oil yield of HDPE plastic as an alternative fuel using parameters of fuel physical characteristics, including density, viscosity, and calorific value. The best results show that the variations of adding 50% and 75% pine bark waste have physical characteristics equivalent to B20 and B30 fuels, with density, viscosity, and calorific values of 0.8307 g/ml, 2.341 cSt, and 10,644.894 cal/g for the 50% pine bark variation, and 0.8367 g/ml, 2.467 cSt, and 10,491.863 cal/g for the 75% pine bark variation, respectively

PERANCANGAN DAN UJI FUNGSI SISTEM PEMBERSIH KANDANG SAPI TIPE PENGIKIS LANTAI MENGGUNAKAN SOROK MEKANIK
Get PDFThe floor scrapping method for cowshed cleaning systems has been widely applied on several modern farms today with the aim of making it easier for farmers to clean the cowshed. The mechanical design of the motor-driven scraper aims to facilitate the cowshed and save human energy. The design method uses James H. Earle method and is continued by carrying out the production process for the cowshed cleaning systems. This system works using a chain to pull the scraper so that it moves to scrape dirt on the floor by pushing it, so that work that was previously done manually can be done more easily with the help of this tool. The designed tool has dimensions of 1000 mm x 500 mm x 300 mm, while the mechanical beam design has dimensions of 700 mm x 200 mm x 3 mm. Based on the calculation results, bending stress data was obtained of 20.534 N/mm2 for the frame and 41.476 N/mm2 for the scraper. Calculation of the transmission system for the cowshed cleaning tool obtained specifications for an electric motor with a power of 0.02 HP, a pulley measuring 72.6 mm, a belt measuring 26 inches, a shaft measuring 12 mm and rolling bearings with a life of 24 years. Then, from the result of testing the frame and scraper using Solidwork software, it was found that the stress was 29.95 MPa for the frame and 67.49 MPa for the scraper. This stress value is declared safe because it is still below the permitted stress. Meanwhile, based on function testing, the most effective nozzle to use is a nozzle with an angle of 15o because it has a higher spray intensity than the others and thus has the highest cleanliness value. Based on test results, the cowshed cleaning tool obtained an average cleanliness score of 75.6 with a time of 60 seconds

Get PDFThe analysis of the economic perspective of the cloth hanger semi-automatic by using the lean manufacturing method was studied and analyzed. The economic balance was consider all cost of manufacturing effort. the cost manufacturing of the hanger is to the device, material, cutting, and drilling steps thus assembly. The investigation is to the manufacturing lead time (MLT), and the brake event point (BEP). Production time per unit (TP), the effective work hour per man-hour, the production capacity (PC), and the Payback Period (PBP). The result of economic balances shows are manufacturing lead time (MLT) of 3,38 hours/unit, and BEP (Q) of 1,65 units per month, further, Break break-even point (BEP) is about Rp. 5.345.740,94 per month. So, the profit taking back regards to production capacity is about Rp. 24,672,650,48 per month after selling. The effective work hour of the man-hour is 6 per shift hour per day. Thus, production time reveals 44,92 min per unit. The production capacity per month is to be 8 hours per day and reveals 20 units. The payback period of the clothes hanger will take back after 2 months for more than 2 units sold. That is, the cost of the engine manufacturing will be refunded after 1 month during normal selling
