As an effort to achieve green campus, The Faculty of Agriculture Engineering (FTP) of Udayana University should perform an audit to know the suitability of the condition of The Faculty of Agriculture Engineering of Udayana University to the green campus using UI green campus metric guide. Some of the criteria that can be audited is the percentage of green area andAudit ofelectricity usage. This research is done to find out the percentage of green area and electricity usage in The Faculty of Agriculture Engineering of Udayana University compared to the criteria of UI green campus metric guide. Percentage of green area is measured using theodolite and the measurement of energy usage is done by Auditing the energy usage of FTP of Udayana universityThe measurement of green area in FTP of Udayana Shows that FTP Udayana has a green area of 4.185,278 m2with the percentage of 43,1% and has a score of 4 with 225 points according to the standard of UI green campus metric guide. As for the electricity usage, FTP has a score of 300 with the usage of 30,75 kWh/person/year. This result shows that in aspect that is shown above, The Faculty of Agriculture Engineering of Udayana University is sufficient with UI green campus metric guide in the criteria of percentage of green area and electricity usage.

Abstract

Tuna fish is a food that people like because it has rich nutrients so it requires continuous treatment to maintainabetter quality. Tomaintain a better qualityof tuna fishis using the liquid smoke method. The application of liquid smoke has many advantages among othermethods because itseasy application, givingthe product distinctive characteristics in the form ofa more attractive appearance, aroma, texture, taste, and does not pollute the environment. The liquid smoke wasused from tabah bamboo (Gigantochloa nigrociliata Buse-Kurz). This study aims to determine the effect of the concentration of liquid bamboo smoke and cooking temperature on the characteristics of Se'i Tuna. The methodused wasa factorial completely randomized design with two factors. The firstfactor is the concentration of liquid smoke (consisting of 2%, 4%, and 6%) and thesecond factor was the cooking temperature (consisting of 80oC, 90oC, and 100oC). The best treatment combination wasat a concentration of 6% liquid smoke and acooking temperature of 100oC byheatingfor 4hours, the water content was50.46%, protein content 17%, pH 5.53, ash content 2.81%, appearance sensory test 8,07, flavor 8,73, taste 8,73, and texture 8,60.

Abstract

The current advancement of hydroponic technology is closely related to advances in automation technology such as the application of IoT. One of the hydroponic systems currently being developed is NFT hydroponics. This system has relatively easy monitoring of temperature, oxygen and nutrients. The purpose of this study was to determine the effectiveness of monitoring, temperature control and nutrition in the hydroponic NFT system. The system design produced in this study includes the use of Arduino Uno as a microcontroller connected to a DHT11 sensor for temperature monitoring, a pH 4502C sensor for monitoring nutrition, while an ultrasonic sensor monitors the level of nutrient water in the hydroponic system of pakcoy plants automatically. The use of pakcoy plants as samples of hydroponic plants with the NFT system is due to their relatively fast-growingvegetable. The results of the study showedthe use of the DHT11 sensor and the electrode sensor with the 4502C module as a nutritional monitoring unit has an accuracy of 98%. This shows that the monitoring and automation systems of the NFT hydroponic pakcoy are running well.

Abstract

Bamboo shoots are saplings of bamboo that appear at the bottom of the soil, bamboo shoots are known to have very high water content and are usually consumed as processed vegetables such as stir-fry, stuffed spring rolls, curry, and pickles. One type of bamboo shoot that grows well in Bali is the tabah bamboo shoots (Gigantochloa nigrociliataBuse-Kurz). Seeing that the water content of bamboo shoots is very high, the shelf life and usability of bamboo shoots can be increased by turning them into semi-finished products in the form of flour. Bamboo shoot flour is oneof the foodstuffs that are dry and also easy to change components. In maintaining the quality of a food ingredient, packaging has a very important role. This research was conducted to determine the right type of packaging in maintaining the quality characteristics of bamboo shoot flour. This study uses a Completely Randomized Design which consists of two factors, the first factor is the type of packaging, namely (K1): polypropylene, (K2): aluminum foil, and (K3): paper sack. The second factor is storage time, namely (H1): 10 days, (H2): 20 days, (H3): 30 days. Parameters observed were water content, water absorption, bulk density, crude fiber, whiteness degree, and sensory test. The results showed that the paper sack packaging type treatment could better maintain the quality characteristics of tabah bamboo shoots flour during storage for 30 days with a water content value of 6.73 %, the water absorption capacity of 10.83 %, bulk density of 0.6445 g/ml, crude fiber. 27.16%, and whiteness degree of 49.47%. By using paper sack packaging, it will better maintain the quality characteristic of bamboo shoot flour during storage so that it does not get damaged quickly.

Abstract

Coffee husks can be used as an alternative energy source which is often found in the agricultural sector as biomass waste. This research was conducted to determine the effect of different temperature variations and carbonization on the quality of coffee husk briquettes. The experimental design of this study used a factorial Randomized Block Design (RAD) with 2 (two) factors. The first factor is the cooking temperature (S) 200°C, 250°C, and 300°C. The second factor is the length of writing time (L) 30 minutes, 45 minutes, and 60 minutes. The combination of a research experiment design with 2 replications will produce 18 experimental units. Parameters observed in this study include moisture content, mass density, compressive strength, ash content, volatile matter, bound carbon, and combustion rate. In this study, the data obtained were analyzed by variance test and continued with Duncan's test if there were significant differences between treatments. The results showed that the interaction of temperature and cooking time had a significant effect on the quality parameters of the briquettes produced. The briquette treatment with the curing temperature used was 300°C and the curing time of 60 minutes (S3L3) was the treatment that produced the best quality briquettes. The characteristics of S3L3 treatment briquettes are that they have a compressive strength of 235.11 kgf/cm2, a mass density of 0.62 g/cm3, a water content of 1.67%, and a combustion rate of 0.012 g/min.
