Naturally, a mother hen incubates her eggs until they hatch completely. However, the success rate of natural hatching is low, and hatching can be completed with a maximum of 10 eggs. Chicken farming, more specifically the chicken egg hatching system, breeders usually use an incubator for the process of hatching chicken eggs. In the incubator, there is a lamp that has been provided which is used for the process of warming the eggs so that the eggs can hatch properly and of good quality with incandescent lamps. In general, the process of hatching eggs often encounters problems or obstacles. The obstacle that is often experienced when hatching chicken eggs is that the incubator only uses incandescent lights. Therefore, to avoid this problem, a microcontroller was designed to overcome this problem. This tool is a combination of a microcontroller with an Arduino-based temperature and humidity sensor. With this tool, after the eggs hatch, when the lights are off, the sensor can read the output in the form of the incubator temperature, which is detected by the Arduino serial display. Design methods and experimental methods were used in this research. Tool testing is divided into three types, namely temperature testing, humidity testing and egg load testing. The result of this research is an automatic egg incubator machine that uses Arduino. Several electronic components used in the incubator are Arduino,

Extensive research has been conducted to investigate the formulation of a new generation of cereal-based Gluten Free (GF) foods formulated with High-Resistant Starch (RS) sources and high in nutritional value. Black glutinous rice flour is a rich in bioactive compound and MOCAF is known for its high RS content often used as an alternative to wheat flour in the production of gluten-free cookies. The formulation of the combination of these two ingredients needs to be investigated to produce gluten free cookies that have good physical and sensory characteristics. The aims of these research was to investigate the effect of different ratio of Black Glutinous Rice Flour (BGRF) and MOCAF (MF) formulation (F1 = 100:0, F2= 75:25, F3=50:50, F4= 25:75, F5= 0:100) on physical and sensory parameter of resultant GF cookies. The results shows that, cookies with high amount of BGRF showed interesting physical properties with higher diameter, spread ratio, and ∆E of the cookies, lower weight, thickness, baking loss, L*, a*, b*, C* value, and the hedonic score of color, aroma, taste, texture, overall compared to cookies with 100% MF. The best formula that produces gluten free cookies with the highest taste score score is F4 (BGRF 25%:MF 75%) with physical characteristics weight 10.70 g, diameter 48.40 mm, thickness 8.60 mm, spread ratio 5.63, baking loss 17.37 %, L* 53.96, a* 0.63, b* 17.65, C* 17.66,   ∆E 48.78. With the combination of BGRF and MF on cookies dough, we manage to obtain cookies that has great potential to increase the nutritional quality of gluten-free food.

Home security system is a term to describe a system of protection for residents in the environment and its surroundings from the interference of crime. A house has been equipped with high technology and can be connected to the security equipment in the house. Home security is made in order to create security, comfort and safety for residents of the house and can maintain the security of the environment without monitoring. Home security can be operated via a microcontroller and a mobile device. Home security in Indonesia is currently classified as very important, this is because the crime rate is increasing every year. The development of home security has been carried out using various existing technologies, such as the nodemcu microcontroller, which is a hardware platform intended to create prototypes of interactive electronic equipment based on flexible and easy-to-use hardware and software. This research was conducted to produce a simple home security system by utilizing nodemcu technology and a combination of sensors and an ESP32 cam as a medium to be able to run sensors and home security cameras. This research was conducted by conducting a literature study, exploring the technologies used, as well as the concept of mobile-based software development. The next step is to define requirements, analysis, design, and implementation (programming and testing the system that has been built).

The elderly group during the pandemic is the group most at risk of experiencing severity/morbidity and mortality due to Covid-19 disease. This is because elderly patients (geriatric) generally have various comorbidities, such as cardiovascular disease, chronic respiratory disease, diabetes mellitus and hypertension. The elderly as a vulnerable group, of course, really need the right information related to Covid-19 with the right media. Media that can be used to provide information on Covid-19 to the elderly are posters and power points. This provision can be done by nurses. This research will be conducted on 50 elderly people at Kelurahan Bendungan Semarang. The study was conducted by measuring the level of knowledge with a knowledge level questionnaire about the problem of covid-19, before and after treatment. The design of this study was a quasi-experimental pre-test post-test with control group. The research sample was determined by total sampling with certain criteria, namely: 1) elderly aged 60 years and over, 2) can read, write, communicate well, 3) do not experience sensory, cognitive, and movement disorders, 4) participate in all activities with 100% attendance. The division of the group was 25 people for the intervention group and 25 people for the control group. The provision of posters and PPT media was held 4 times in 4 weeks. This is done in combination because the combination of the two media can increase the level of better knowledge, especially for the elderly who have experienced a decline in function. There is an increase in the level of knowledge from low level 4 people (16%), medium level 15 people (60%), high level 6 people (24%) to low level 1 person (4%), medium level 9 people (36%), high level 15 people (60%).

Es krim adalah produk pangan beku yang dibuat dengan kombinasi proses pembekuan dan agitasi dengan bahan-bahan yang terdiri dari susu, pemanis, pengemulsi, penstabil dan flavor. Penambahan buah bit dan berbagai jenis gula dapat meningkatkan nilai gizi es krim. Penelitian ini bertujuan untuk mengetahui aktivitas antioksidan yang tertinggi pada produk dan mengetahui karakteristik kimia, fisika, dan sensori es krim buah bit. Penelitian ini menggunakan metode Rancangan Acak Lengkap (RAL) dengan menggunakan dua faktor. Faktor pertama adalah bubur buah bit (20%, 30%, dan 40%) dan faktor kedua yaitu jenis gula (gula pasir, gula stevia, dan madu). Hasil penelitian menunjukkan bahwa  perlakuan es krim yang terbaik diperoleh berdasarkan aktivitas antioksidan tertinggi es krim yaitu pada perlakuan bubur buah bit 40% dan jenis gula berupa madu. Pada perlakuan tersebut memiliki karakteristik: aktivitas antioksidan 32,474% kadar protein 2,139%; kadar lemak 0,145%; kadar gula total 7,064%; overrun 14,172%; kecepatan meleleh 36,660 menit; warna  2,958 (ungu); rasa manis 2,500 (sedikit manis); tekstur lembut 3,216 (lembut); flavor buah bit 3,342 (semakin nyata); dan kesukaan keseluruhan 2,705 (sedikit suka). Kata kunci: Es krim, buah bit, jenis gula ABSTRACTIce cream is a product of frozen food that made with a combination of the process of freezing and agitation with ingredients consisting of milk, sweetener, emulsion, stabilizer, and flavor. The addition of beet fruit and the kind of sugar can improve the nutrition value of ice cream.
