Salted fish is one of the side dishes that are in great demand by the people of Indonesia. This study aims to analyze the effectiveness of the use of direct sunlight on the drying process of salted fish without formalin. The method used in this research is the experimental method. Where this data collection uses various types of fish to be used as salted fish and there are also some fish that are not salted. The types of fish used in this study were river fish, tilapia, singkek fish, and marine fish. The process of making this salted fish lasts 3-5 days. It depends on the type of fish used and the weather or sunlight during the drying process. The drying process of salted fish that is applied is using direct sunlight or traditionally and does not use chemicals or formalin. The results obtained during drying, fish that do not use salt easily spoil quickly and cannot last long. The smell of unsalted fish is more pungent and the color of the fish also changes. While the fish that is given salt does not smell bad, the color of the fish also does not change.

Drying fish is one way of preserving fish by reducing the water content of fish so that the activity of microorganisms can be reduced. Preservation by drying is intended to extend the shelf life of fish. Many fish species have used the drying method for a long time. This study aimed to analyze the effect of drying on salted and unsalted fish to test the resistance and quality of fish. Making salted fish is the simplest preservation with low cost. The characteristics of fish that have a neutral pH, soft texture, and high nutritional content make fish a good medium for bacterial growth. Most Indonesian people manage fish to overcome the damage, including those processed into salted fish. Salted fish is one form of traditional fish processed products with drying and salting technology. Based on the study's results, it was concluded that salted fish that was dried for more than 12 hours of heating in the sun produced products that were acceptable to consumers, while drying under 8 hours produced products that consumers did not accept. There is a need for further testing on the shelf life and the need for the use of hygienic packaging. Based on the analysis, the concentration of salt and time of salting did not significantly affect the texture and aroma.

Fish is a source of animal protein that is widely consumed by the public. With a high protein content, fish quickly undergo a post-harvest decay process if it is not directly processed into food. In general, what causes fish to rot quickly are bacterial and chemical factors. as for the method used in this study is a qualitative research approach. The purpose of this study was to determine the effect of drying on the quality of fish. The results showed that the drying time of fish depends on the weather and also the size of the fish. Drying using sunlight is widely used because heat energy is abundant and the equipment used is inexpensive. during the drying process cleanliness must be monitored. This study also aims to determine the difference between drying fish using salt and not using salt. The parameters observed were the quality of the fish starting from the texture, color, smell, and content contained in the fish after drying. Drying salted fish is widely available in Indonesia, on a national scale salted fish is one of the fishery products that has an important position. The technique of drying salted fish using sunlight is a common technique carried out in Indonesia with the position of the fish being hung and then placed outside or under the sun.

The automotive shop is a business engaged in the automotive sector that serves vehicle repairs and sales of various kinds of vehicle spare parts. A marketplace is a place for buying and selling or a market that uses internet media. The current marketplace is still very common, making it difficult to find a marketplace that focuses on the automotive sector and difficult to find information about available automotive shops around. The automotive shop marketplace system can help to carry out the process of buying and selling vehicle spare parts and assist in finding various spare parts and information about available automotive shops based on the user's location. This system was developed on a web-based basis using the PHP programming language with the Laravel framework and integrated with the Leaflet API, RajaOngkir API, and Midtrans Payment Gateway as additional features in creating a marketplace. The leaflet API displays a map containing the location of the automotive shop listed on the marketplace. RajaOngkir API provides information about shipping costs to the buyer's place from the seller's place. Midtrans Payment Gateway bridges the payment process carried out by both parties so that it can take place properly. The method used in this research is to use the System Development Life Cycle (SDLC) waterfall method. The results of the research conducted were tested using the black-box method.

Currently, there are still many students who like digital-based learning activities. This study aims to analyze the need for developing Android-based mobile learning media in SMK. The type of research used is survey research and literature study. The methods used in collecting data are observation, interviews, and questionnaires. The instruments used are interview sheets and questionnaires. The data analysis technique used is descriptive statistics. The study results showed that around eighty-two percent of students actively use smartphones outside learning hours. Students who use smartphones in learning are more informal, using them more to find information. On the other hand, only twenty-five students use smartphones to access course materials. Students agree to use their smartphones to study in class because it can increase their interest in learning and their ability to understand the subject matter better. Learning media can be a source of learning for students and help teachers in teaching, and learning activities can be more effective.
