Honey is a natural liquid that contains a lot of sugar produced by bees (genus Apis) from flower nectar and has a sweet taste. Honey contains a multitude of benefits that are good for the body, including being a source of nutrients, improving body metabolism, anti-bacterial, and others. The purpose of designing the Honey Harvest Monitoring System with ARDUINO-based IOT is to help breeders maximize honey harvesting results. This study aims to design an intelligent system for controlling the temperature in bee hives, humidity in bee hives, and monitoring honey yields, measuring the temperature and humidity of the storage room using DHT 11 sensors, and monitoring honey harvest time using Load Cell sensors. The temperature and humidity controller in the cage uses a blower/fan. Sensor data will be processed using the Wemos D1 R1 microcontroller and then sent to an Android application via the internet network using a real-time Firebase database so that it can be accessed anywhere and anytime. The way this system works is that if the room temperature is >38 degrees Celsius, the blower/fan will turn on, and will turn off if the temperature is 40%, the artificial window will open and will close if the humidity is

Indonesia is a country that has potential water resources due to high rainfall but is very vulnerable to water crises. This fact shows the great urgency of the need for clean water. One effective solution to deal with this is through the use of rainwater. Harvesting rainwater is an effective step because Indonesia itself has high rainfall so that during the rainy season the product from PT Wujudkan, namely Gama Rain Filter, will collect water and in the dry season it will be used for daily needs. The purpose of this study is to find out about the implementation of the gamma rain filter in increasing access to clean water in rural communities. The research method used is a qualitative approach to gain a deep understanding of the effect of the Gama Rain Filter installation in increasing access to clean water in rural communities. The findings of this study are that with this superior technology, Gama Rain Filter helps people save water resources for drinking purposes during the rainy season. Therefore, existing funds can be used to obtain food sources that contain lots of protein

Medokan Ayu Village is 3 km from the UPN "Veteran" East Java campus. The location of this service is located in Griya Amerta Housing RW 15, Medokan Ayu Village. Like housing in general, residential land area is usually relatively small, has relatively narrow yards and the distance between houses is also close to each other. So that the area of ​​the yard owned by the community for cultivating crops while developing agriculture is not very supportive. Verticulture or what can be called vertical farming is a system of cultivating plants vertically, so that the planting medium is put in a container that stands and rises up. This cultivation technique can be used in two ways, namely with water and soil as the planting medium. Pakcoy can be harvested when it is 40-50 days old, while curly lettuce can be harvested when it is 40-60 days old. This verticulture cultivation uses a mixture of several planting media such as soil, cocopeat, roasted husks, and kohe. The goal is for the plants to meet their nutritional needs and nutrients, so that the plants can grow optimally and have good quality.

Shallots are a spice plant that is very easy to find in various regions, especially in Nganjuk Regency. Red onion is a commodity with a short shelf life. The tubers rot easily due to their high water content. During the main harvest, red onion production is abundant, the selling price drops, causing losses to farmers. To overcome this, it is necessary to manage red onions, including making fried shallots because fried shallots are often used by the community as a cooking spice or as a complement to the daily food menu. This phenomenon is utilized by Puspita Makmur managers to produce preparations from shallots. The KKN-T 67 Musir Kidul group helps Puspita Makmur MSMEs to attract public interest so that they can reach all groups by innovating product diversification.

Street vendors are the dominant informal economic activity in urban areas. These street vendors are a form of scale economic activity that can produce and or distribute goods and services. Goods sold on roadside and in city centres that are busy with visitors provide necessities for the lower middle class, but it is not uncommon for people from the upper middle class to buy wares from street vendors. The purpose of writing this research is to. This study uses a normative juridical method. The results showed that the street vendors in the UPN Veteran Jakarta environment had filled the sidewalks on the road in front of the UPN Veteran Jakarta campus. Which is where the road or sidewalk should be used by pedestrians so that it is difficult for pedestrians to pass through the road because the road is narrow and there are many vehicles passing by. Thus, it can be concluded that the existence of street vendors, especially those selling in the UPN Veteran Jakarta Campus Pondok Labu environment, clearly violates laws and regulations. This is because the stalls used by street vendors for selling use roads and sidewalks which can disrupt traffic order and deprive pedestrians of their rights. Apart from that, this also damages the beauty of the city's spatial planning which causes the locations where street vendors sell their goods to look shabby and dirty.

Dengue Hemorrhagic fever (DHF) is caused by a dengue virus that spreads through the bite of the Aedes aegypti mosquito, which breeds a lot in densely populated areas with humid and warm climates. Anti-mosquito drugs in the form of burns, sprays, lotions, or other types are already widely used, but these anti-mosquito drugs are not entirely beneficial. This research is purely experimental research with Post-test Only Control Group Design by making air spray solution products from noni leaf infusion and cananga flower, which are analyzed descriptively and analytically. Experiments carried out with Randomized Complete Design 1 time repetition to analyze effectiveness. The study used two factors: treatment (P) using infusion products while the control (K) using distilled water. From the results of mixing, it was obtained as much as 400 ml of infusion solution. Obtained in each measurement, there was a reduction in live larvae until the last measurement. Noni leaf contains five flavonol glycosides (flavonoid compounds) as respiratory poisons and a combination of saponins and tannins as stomach poisons that have the killing power against the death of Aedes aegypti larvae. Cananga flower extract itself can resist mosquitoes because of the content of linalool, geraniol and eugenol. This makes a change in the larvae's behavior, where the previously active movement will be slow and eventually will die.

Food and agricultural products are perishable, so they have the potential to experience losses, both in quality and quantity during the post-harvest process and processing due to physiological changes in the form of physical, chemical and microbiological. As an effort to reduce losses during post-harvest and physiological changes, it is necessary to apply appropriate technology (appropriate technology). The application of ozone technology in the handling of fruits, vegetables and fishery products has good prospects because it is felt to be safe and effective. Ozone (O3) has the main function, namely as an oxidizer and disinfectant or a combination of these two functions. The high oxidation potential of ozone can be used to kill bacteria (sterilization process), remove color (decolorization process), remove odors (deodorization process), and decompose organic compounds (degradation process). The treatment of ozonized water in the storage of food products and agricultural products does not damage their nutritional content, because the ozone content itself will be lost by evaporation. If ozone is exposed to sunlight it will break down into oxygen compounds again. Utilization of ozone technology is widely used to reduce contamination and extend the shelf life of fresh fruit, vegetables and fishery products. This paper examines and synthesizes several research results related to the use of ozone for fruits, vegetables and other agricultural commodities during the postharvest process and handling of agricultural products.
