Abstract

The photosynthesis process in indoorcultivation system does not get optimal sunlight, therefore LEDs can be used as artificial light. The red-blue color is a color that has a positive effect on plant growth. In addition, to increase the rate of photosynthesis, one of the technology advances that can be used is sonic bloom. Sonic bloomis the delivery of high-frequency sound wavesin plants to stimulate the opening of the leaf stomata mouths which is accelerating the rate of absorption of carbon dioxide, water and soil minerals. In this study,Pakcoywas exposed to jazzmusic to determine the effect on production of Pakcoy,and the best length of exposure. The length of exposure to jazz musicwas 1 hour, 2 hours, 3 hours, 4 hours,and 5 hours starting from 07.00 WITA. The type of jazz music used wasJazzRock with the musical instrument Gambandellaby Psychedelic Jazz-Rock Fusion with a frequency of 86 –21189 Hz and a sound intensity of 65-95 dB. In the growth chamber, artificial light red-blue LED was used with a light intensity of 1900 –2100Lux. The results showed the lengthof exposure to jazz music significantly affected the production of Pakcoy. The exposure length of 5 hours showed the best result (fresh harvest weight 55.49 gs, root wet weight 2.18 gs, and biomass 2.95 gs). In conclusion, exposure length to jazz music has a positive effect on Pakcoyproduction.

Abstract

Candikuning Village’s land is located in the highlands with topography ranging from flat to very steep and high rainfall intensity, causing land erosion. Therefore, research related to erosion using the RUSLE method is necessary. The RUSLE method measures five parameters: rainfall erosivity, soil erodibility, length and slope index, land cover vegetation index, and land management index. This study aimed to determine erosion values and erosion danger levels of the land. Based on overlaying soil type, slope, and land cover maps, 40 land characteristic units were identified. Analysis showed that Candikuning Village’s rainfall erosivity was 239.82 MJ mm/ha/hour/year. Soil erodibility parameters ranged from 0.18 to 0.53. Length and slope index values based on slope classification were 0.29–1.79 for flat land, 1.97–3.70 for sloping, 2.94–7.23 for slightly steep, 6.11–10.17 for steep, and 10.25–13.42 for very steep land. Land cover vegetation index included 13 vegetation types with C index values of 0.001, 0.3, 0.4, 0.6, 0.7, and 1.0. Land management index had six management types with P index values of 0.032, 0.4, 0.5, 0.75, 0.9, and 1.0. Based on RUSLE calculations, erosion prediction values ranged from 0.11 to 313.59 tons/ha/year. Land categorized by erosion danger levels very light, light, medium, heavy, and very heavy covered areas of 1,552.92 ha, 260.54 ha, 124.12 ha, and 23.84 ha, respectively, with no land classified as very severe.

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.

Abstract

Traceability is the capability to track the movement of products through the stages of production to distribution. Food industry regulations require traceability to be included as a criterion in quality control, which must be audited periodically. One participant in the retail industry, BOS Fresh, has obtained certification as a Self-Reliant Agricultural and Rural Training Center (P4S). One of BOS Fresh's products, broccoli, is highly demanded and has substantial transactions. The traceability system at BOS Fresh still has limitations in conveying information to consumers. The primary objective of this research is to develop a traceability website based on the Laravel Framework that is excellent, responsive, and accessible to users. The development of the traceability website employed the waterfall method, covering the design of use case diagrams, class diagrams, database, user interface, hosting, and culminating in white-box, black-box, and user acceptance testing. The admin user interface comprises multiple menu options, including login, data input, data update, data deletion, and QR code printing. Consumers are only granted access to a page for viewing data. Performance testing results of the white-box method, directly tested by the web developer, obtained an interpretation of "Valid" for testing the logical pathways within the programming. The black-box method, tested by the BOS Fresh admin, received an interpretation of "Successful" for testing all website features. Additionally, the user acceptance testing method, conducted directly by BOS Fresh consumers from general backgrounds, yielded an interpretation of "Very Satisfied" in assessing user satisfaction. Based on the test results, it can be concluded that the constructed traceability website operates with excellence, responsiveness, and user accessibility.
