This study uses a quadratic sampling method with a plot size of 10 m x 10 m, which totals 10 plots. Results of research on plant vegetation analysis wild, which has the potential to be a refugia in the rice farming area of Jombang District. For the development of e-catalog teaching materials, 338 individuals, consisting of 11 plants, including: Mimosa pudica (Embarrassed Daughter), Eleusine indica (Grass reeds), Ricardia scarbra (coarse clover), Digitaria ciliaris (kebo grass), Ipomoea quamiochit (Earth detail), Amaranthus (Spinach thorn), Euphorbia hirta L.

Most Indonesians consume crackers because they are delicious and can be consumed with any meal. This resulted in the proliferation of cracker manufacturers in Indonesia, not only producing a single type of cracker but also a variety of crackers whose flavor and ingredients were adapted to the palate of the Indonesian people. Crackers made from leather or Rambak crackers are well-known among the general population. Rambak crackers are not significantly distinct from other types of crackers. The difference is in the ingredients. Rambak crackers are made from various ingredients, including cow, buffalo, rabbit, chicken, fish, tapioca flour, and flour. In making these Rambak crackers, however, cowhide is typically employed. Cow leather is one of the products of the livestock sector, which, according to the Central Statistics Agency of Jember Regency, produced 11,287 pieces of leather in 2019. This demonstrates that Rambak tapioca cracker ingredients are not readily available on the market. Consequently, a Decision Support System (DSS) is a system that can provide problem-solving and communication capabilities in semi-structured and unstructured environments. Positive Distance from Average (PDA) and Negative Distance from Average (NDA) are the two distance measures used in the Evaluation Based on the Distance from Average Solution (EDAS) method. The best alternative will be the one with the highest PDA value and the lowest NDA. Based on the User Acceptance Test (UAT) results of the system, which the Wanteyan Home Industry well received, this decision support system yields 5%.","PeriodicalId":302680,"journal":{"name":"Jurnal Sains dan Teknologi (JSIT)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132357362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Spinach plants cannot grow properly if the water content in the soil does not meet the needs of the plants. In addition, spinach plants are susceptible to pest attacks that can damage the leaves. From these two problems, we need a system of automatic watering and pest control devices that can monitor plants. To make it easier to plant spinach, a monitoring system is needed using a website, because its use which can be accessed anywhere for 24 hours can make it easier to monitor the condition of spinach plants. The website will display soil moisture and PIR sensor data readings sent via the NodeMCU ESP8266 microcontroller to a database in the form of soil percentage, soil status, and plant conditions.","PeriodicalId":302680,"journal":{"name":"Jurnal Sains dan Teknologi (JSIT)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116674239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Association of Farmers Groups (GaPokTan) Mekar Jaya Mandiri in Cikupa Village, Karang nunggal, has agricultural land planted with watercress as the main source of income. Watering the water spinach plantations is carried out using a piping system with the distribution of water divided into two groups of blocks which is carried out by adding two ball valve mechanisms as a distribution system. The addition of 2 ball valves created problems for the operator. The work cycle when adding two ball valves is 12 body positions in operating the valve, including walking towards the valve, standing straight, and bending when opening or closing the valve. Walking and bending when opening or closing the ball valve takes a long time. Productivity was increased by developing two ball valves with an automatic valve system called the Motor Operated Valve (MOV). MOV uses an albino program for its operating system, and the operator controls M0V via cell phone. Comparison of work cycles between ball valves and those using MOV. The working time cycles for the redesigned operator open and close the valve is 63 seconds with 12 movements. The longest time is walking towards the valve, which is 16 seconds. After the redesign, the operator only needs a cell phone to operate the valve application so that the movement goes to the valve is 0 seconds, and the work cycle time after the redesign is 6 seconds","PeriodicalId":302680,"journal":{"name":"Jurnal Sains dan Teknologi (JSIT)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132572955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the researcher is to find out how the model of cloud data storage and data security of cloud computing systems. In this research, researchers propose an efficient method for providing data storage. Security in cloud computing uses a new public key algorithm based on a linear block cipher. This algorithm has been proven by previous studies such as Data encryption, E-commerce, Digital signature. In research, researchers apply the same algorithm, namely cloud computing. In this algorithm several important security services are included such as key generation, encryption and decryption provided in the cloud computing system.
