“…Hasil panen udang yang melimpah di Lampung memiliki potensi limbah yang dapat dimanfaatkan. Jdawisastra mencatat terdapat 80-90% ekspor udang dilakukan dalam bentuk beku tanpa kepala dan 75% dari total berat udang merupakan bagian dari kulit dan kepala (Judawisastra et al, 2012). Pernyataan tersebut menyebutkan bahwa 75% udang merupakan limbah udang yang dapat digunakan.…”

This research aims to analyze the potential of shrimp waste as a lightly processed food in the village of Bumi Dipasena, Lampung. The research method used in this research is qualitative with a descriptive approach. The results of the study show that shrimp waste has the potential to provide added value to the surrounding economy, with the potential of reaching 600 kg in one month. Waste processing has received support from the Maritime Affairs and Fisheries Service of Tulang Bawang Regency with the help of more fantastic boxes. The strategy for utilizing shrimp waste is to utilize the strengths possessed by shrimp waste, namely: New Processed Products; Distinctive and delicious taste; Shrimp shell waste contains protein, calcium, and chitin; shelf life of shrimp shell waste products that can last a long time without preservatives. In addition to taking advantage of existing strengths, it is necessary to make efforts to minimize existing weaknesses, namely by: Establishing a lightly processed food production site in a strategic place; training and preparing human resources in the production process; establishing cooperation with parties that can support smooth production so that the availability of lightly processed food products and prices can continue to be competitive and sustainable.

An Arduino-based stepper motor was used to create a nanofiber spinning machine. The hardware for this tool includes an Arduino Mega module, a 4x4 keypad, a TM1637 type seven-segment display, and L298N type stepper motor driver, a 17Hs4401 type stepper motor, a Pushbutton, and an ultrasonic sensor. The software utilized is the Arduino IDE, which is written in C. This tool's operating premise is that the Arduino processes input from the Keypad, and then the Stepper Motor Driver drives the stepper motor, which moves the collection drum up and down. The results of reading the tool will be presented in the seven segments in the form of RPM, altitude, and time. The tool has a height range of 1-10 cm, an RPM range of 10-100 RPM, and a time range of 1 minute to 1 hour. According to the test results, the tool has 99.8 percent accuracy at RPM, 99.92 percent accuracy at the time, and 97.89 percent accuracy at altitude.

Lower Back Pain (LBP) is common healthproblemin societywithprevalence80-85%. One of the causes of LBP is Herniated Nucleus Pulposus (HNP). This disease occurs in intervertebral discs (IVD), supporting the spine, found a gel fluid called Nucleus pulposus (NP) at the center surrounded by 15-20 concentric thin layers of the Annulus fibrosus (AF). This gel that will come out through AF and nerve pinched behind which makes sufferer feel pain and numb. Handling HNP with physical therapy only reduce the pain and not totally cured. While the surgery use discectomy method by eliminating the protruding parts NP or in whole, but has some drawbacks, such as: high cost, wide surgical incisions, probably occurrence of bleeding or other neurological disorders. Solving problem with find new methods that are faster, easier, and more affordable, we analyze using of alginate/PVA composite with chitosan suspense as a reinforcement as hydrogel injectable material to replace NP. Independent variable is chitosan percentage each sample, as much 5; 10; 15%. This study as a purpose to know mechanical properties, biocompatible, injectable performance, viscosity of alginate/PVA/chitosan, SEM-EDX test and FTIR test. The best result got is addition chitosan 15% appropriate as NP replacement.
