<![CDATA[Aerator sering digunakan pada kolam budidaya udang karena berperan meningkatkan kualitas air dengan cara meningkatkan oksigen terlarut. Kadar oksigen terlarut yang cukup sangat dibutuhkan oleh udang untuk dapat berkembang dengan baik. Berdasarkan hal tersebut, aerator sangat berperan penting untuk meningkatkan budidaya udang. Namun, pemakaian aerator secara terus menurus dapat menyebabkan peningkatan biaya produksi berupa pemakaian listrik. Selain itu, pemakaian aerator secara terus menurus juga dapat memperpendek usia pemakaian aeorator itu sendiri. Dengan demikian, penelitian ini telah menghasilkan sebuah prototipe kontrol aerator secara automatis sehingga diharapkan dapat mengatasi masalah tersebut. Prototipe ini juga berbasis Internet of Things (IoT) untuk mengetahui suhu air kolam melalui smartphone pengguna. Prototipe ini mengaplikasi Wemos D1R2 sebagai prosesor untuk mengontrol aerator serta terhubung ke jaringan internet untuk mengaplikasikan teknologi IoT. Selain itu, aplikasi Blynk IoT juga digunakan pada smartphone pengguna agar dapat terhubung ke prototipe yang dibangun. Beberapa modul lain seperti sensor DS18B20, LCD, relay juga digunakan untuk kinerja prototipe yang dihasilkan]]>

<![CDATA[With the increasing science of technology, especially in the industrial world, currently experiencing increasingly rapid progress will bring consequences and influences to the continued need for various tools to facilitate and expedite work in various fields both as complements and main products. This is what drives us to design, build and analyze an APAR (Light Fire Extinguisher) using the basic ingredients of durian seed flour and Nitrogen (N). The material used in making this apar is carbon steel with a length of 530 mm, diameter: 150 mm and tube thickness of 6 mm. Because of the static fluid in the apar, the analysis carried out is load static analysis on durian seed flour apar tubes using the CAE (Computer Aided Engineering) method, which includes stress, strain and changes in shape / displacement on each element of the durian seed flour fire extinghuisher tube with normal pressure variables of at least 16 bar and a maximum of 18 bar. The results of this analysis showed a stress of 0.607 N/m and experienced an ESTRN strain of 2.817e – 06 then underwent a change in shape / displacement of 1,000e – 30 mm at a normal pressure variable of at least 16 bar. Then with a normal pressure variable of a maximum of 18 bar get a stress result of 0.545 N/m and experience an ESTRN strain of 2.817e – 06 then experience a change in shape / displacement of 1,000-30 mm.]]>

<![CDATA[Inventory is one of the assets contained in the company. Stock plays an essential role for companies because Inventory must be planned and controlled properly. Inventory control is seeking the availability of raw materials so that there are no shortages and excesses. ABC classification is a method used to classify goods based on the ranking or order of the cumulative percentage value of absorption of funds and the cumulative percentage of raw material use, which are then sorted from the highest importance to the lowest value and are divided into groups A, B and C. Inventory is carried out to exercise control using Min-Max Stock; if the stock has exceeded the minimum limit, then a Re-Order must be made, and the maximum limit is the availability limit. The results of the ABC classification with the cumulative percentage of capital absorption and the percentage of use of raw materials show that the factory must focus on paying attention to handling the availability of suitable materials so that no buildup can cause damage and its availability is maintained. Proper handling so that the raw materials are not damaged due to accumulation and to avoid running out of raw materials, the Min-Max Stock method takes into account the amount of Safety Stock that must be in storage so that the production process can run smoothly if there is an additional need for raw materials or occurs late arrival of raw materials. In addition, so that there is no accumulation of raw materials in storage]]>

<![CDATA[This study uses the Quality Loss Function as a way to see product variations on production costs. Quality Loss Function int is also used to indicate that a product or service is related to quality based on standards. Function of quality loss describes the functional relationship between deviation and loss, and it is usually used to assess the direct relationship between quality loss and damage in a refinery production process. From the results of data analysis and processing of data on the two parameters of color and FFA it is that the biggest cause of product damage is material factors,this is due to the fact that there are still many raw materials that do not comply with the parameters that have been set. From the results of research on RBDPKO products, for the cost of product repairs borne by companies with quality characteristics of smaller the better type is Rp. 743.719.690,62.]]>

<![CDATA[Domestic products can be used to increase productivity and competitiveness in international markets. The government stipulates the use of domestic products by setting the sum of the value of the domestic component level and the weight of company benefits at 40%. Until now, there has not been much use of domestic products in the construction sector. Therefore, this study considers the value of the domestic component level in high-rise building projects to strengthen Indonesia's competitiveness in the industrial sector. In this study, the calculation method and value of the domestic component level will be analyzed along with the weight of benefits of construction service companies for multi-story building construction projects. The technique used in this study is quantitative, and it processes data such as technical specifications, cost budget plans, unit price analysis of work, and finding the percentage level of domestic material components through the Ministry of Industry website. The result obtained by this study is the percentage value of the domestic component level (TKDN) in high-rise building projects is 74.53%, the percentage value of the company's benefit weight is 3%, and the total value of TKDN and BMP is 77.53%. The conclusion obtained in this study is that the high-rise building project has met the requirements in the Presidential Regulation of the Republic of Indonesia Number 12 of 2021 concerning the Procurement of Goods and Services.]]>
