The food and beverage industry is currently rife in urban and outside cities. Many locations are used as places to sell drinks, especially coffee which is a native plant of Indonesia. Nowadays, coffee compounding requires good technology. There are many coffee processing machines on the market. The coffee machine is capable of making expresso coffee, latte coffee and others. This coffee machine also combines coffee ingredients, sugar and milk as a carrier for a delicious aroma. In addition, the water pressure from the coffee machine heating boiler, the strong pressure of the coffee machine piston also affects the results of making a cup of coffee, the stronger the pressure, the thicker the coffee produced and the slower the flow of water in the coffee machine. glass of water because basically the stronger the pressure applied to it. the coffee grounds, the tighter and tighter the gaps that the water itself will pass, as well as the thickness of the resulting coffee water will be more concentrated. With Fuzzy Inference, it is possible to determine the optimal pressure to be exerted by the coffee machine piston based on the weight of the coffee grounds (grams) on the coffee machine piston and the specifications of the type of coffee machine used. Determining the optimal pressure on the coffee grounds will affect the taste of the coffee water produced and the speed of making a cup of coffee. This study uses the optimal pressure on the piston using the fuzzy inference method. The purpose of this research is to create a simulation for evaluating the performance of a coffee machine using fuzzy logic to solve the problem of damage to the piston. The fuzzy approach in this research uses the fuzzy Takagi Sugeno Kang method.

The library can be referred to as a storage place for books and other references. The reference can be in the form of digital storage media. Libraries if not managed properly will cause chaos in the library organization. Many books were lost due to the entry and exit of books that were out of control. Currently, the library is not only a place to store books but can be maximized by managing and adding other digital devices. The use of Radio Frequency Identification (RFID) in libraries adds sophistication to the management of books and library items. In addition, currently many libraries have taken advantage of Internet of Things Technology, by adding various sensors and integrating with cloud-based storage devices. It provides a service that makes it easy for library members to find and track the current whereabouts of books. This research does not only create a library by providing hardware in the form of sensors to be installed in the library. This paper also proposes the use of smartphones as an alternative in replacing sensor hardware. This study uses a QR Code sensor to match the book you are looking for and simulates dancing a book in blocks and bookcases. with augmented reality. The purpose of this research is to make a smart library prototype to make it easier for library members to find books or other references. The results of the experiment to find books and DVDs that have been carried out achieve an accuracy of 83.33%.

Background: Basis gigi tiruan umumnya dibuat menggunakan polimer PMMA dikarenakan sifat-sifat dan kelebihan yang dimiliki, namun ada beberapa kekurangan sehingga dilakukan berbagai upaya untuk menegakkan sifat-sifat tersebut, salah satunya dengan penambahan metal oxide titanium dioksida nanopartikel. PMMA-TiO2 memiliki beberapa kelemahan diantaranya adanya pembentukan aglomerasi akibat kurangnya dispersi yang kurang baik dan menyebabkan ikatan atau adhesi yang kurang diantara mereka sehingga perlunya dilakukan grafting atau memodifikasi permukaan dari TiO2 dan dilakukannya silanisasi. Silanisasi merupakan metode pengaktifan dari silane coupling agent agar dapat berperan sebagai jembatan molekuler antara bahan organik dan anorganik melalui reaksi hidrolisis yang menghasilkan gugus silanol (Si-OH) dan berikatan dengan gugus hidroksil (OH) pada substrat membentuk ikatan hidrogen, kemudian reaksi kondensasi yaitu pelepasan molekul air (H2O) sehingga membentuk ikatan Si-O-Ti. Tujuan literatur ini adalah mengulas jenis ikatan polimer PMMA-TiO2 dengan penambahan silane coupling agent.Method: Pengumpulan literatur yaitu dengan menggunakan metode PICO (Problem, Intervention, Comparison, Outcome) dengan menulusuri basis data elektronik PubMed, Science Direct, dan Google Scholar.Result: Ikatan polimer PMMA-TiO2 yaitu ikatan van der Waals yang merupakan ikatan lemah. SCA ditambahkan agar terbentuk ikatan yang kuat yaitu ikatan kovalenConclusion: Ikatan PMMA-TiO2 akan lebih baik menggunakan silane coupling agent sebagai jembatan molekuler sehingga menciptakan adhesi yang baik dengan terbentuknya ikatan kovalen

Background: Dental and oral health is an important part of overall body health. Cavities are one of the most common dental and oral problems experienced by people in the world, including in Indonesia. Cavities must get treatment as soon as possible before causing unwanted things. The increasing and growing use of filling materials is in line with increasing public awareness of dental and oral health. However, this is not evenly distributed in all regions, only areas that have adequate access and technology can reach this information, so education efforts are needed for people outside the area. Health education is one of the efforts to increase knowledge, attitudes, and good practices in individuals, groups, or communities in maintaining and improving public health. The locations that are targeted in this community service are villages in the working area of the Margasari Health Center, Tegal Regency, Central Java. Method: The planned educational activities include surveying the problems encountered, counseling and discussions on the topic of introducing dental fillings in children and adults. This community service aims to increase public awareness of the importance of treating cavities and increase public understanding regarding the choice of materials used in the treatment of cavities. Result: Counseling begins by distributing questionnaires before and after the counseling. The selected counseling material is material about various additives commonly used in dentistry. The data was then entered and it was found that there was a significant difference between before and before the research was carried out, the p-value was 0.000. Conclusion: The education provided through counseling can be concluded as effective in increasing the knowledge of the people of Margasari Village.

Background: Caries is a chronic disease of the dental hard tissue. The main cause of this disease is plaque bacteria, starting with the formation of white spot lesions due to the dissolving of minerals in tooth enamel caused by acids from the metabolism of bacterial carbohydrates. Caries often occurs in elementary school children because they tend to consume a lot of cariogenic food. The prevalence of caries can be reduced by preventive efforts. Several preventive efforts can be made by providing sufficient information, reducing cariogenic food consumption, always maintaining oral and dental hygiene and preventive dentistry actions. Method: This community service located at SD N Margasari 07. The counseling activity uses phantom and video animation followed by DMF-T/def-t data collection. Result: It was found that 41.8% of students had high category DMF-T/def-t index Conclusion: It is necessary to have a sustainable program to increase children's knowledge and awareness in maintaining dental and oral hygiene including promotive, preventive and curative efforts.

Background: The type of fiber often used in dentistry is E-glass fiber, which has limited availability and relatively high prices. Non-dental glass fiber can be employed as an alternative in dentistry because its composition is nearly identical to E-glass fiber. Exposure of restorative materials to artificial saliva, designed to mimic the properties of normal human saliva, affects the mechanical properties of non dental glass fiber, including tensile strength. This research aims to determine the effect of immersion duration of non-dental glass fiber reinforced composite in artificial saliva on tensile strength.Method: The research method used is laboratory experimental analytic with a post-test only control group design. Samples are divided into three treatment groups with immersion in artificial saliva for three times (2, 7, and 14 days). Tensile strength is conducted using a Universal Testing Machine (UTM).Conclusion: The conclusion drawn from this research is that immersion duration in artificial saliva has a significant effect on tensile strength of non-dental glass fiber reinforced composite. The tensile strength of non-dental glass fiber reinforced composite after immersion for 14 days shows higher results compared to immersion for 7 and 2 days.
