Parameter penelitian yaitu susut bobot, intensitas kerusakan, color difference, kekerasan buah, nilai total asam, total padatan terlarut dan uji organoleptik terhadap warna daging buah, rasa daging buah, aroma daging buah. Pengamatan dilakukan selama 25 hari penyimpanan pada suhu ruang (28-31ºC). Hasil penelitian menunjukan pemberian uap etanol secara tunggal berpengaruh nyata terhadap susut bobot sedangkan pelapisan kitosan secara tunggal berpengaruh nyata terhadap total asam dan total padatan terlarut. Interaksi pemberian uap etanol dan pelapisan kitosan berpengaruh nyata terhadap susut bobot, intensitas kerusakan, color difference, kekerasan buah, dan organoleptik terhadap warna daging buah, rasa daging buah, serta aroma daging buah. Perlakuan E2C1 merupakan kombinasi terbaik yang mampu mempertahankan mutu dan masa simpan buah manggis hingga 10 hari, karena memiliki nilai perubahan paling rendah pada parameter yang diamati seperti susut bobot, intensitas kerusakan, color difference, kekerasan buah, dan memiliki nilai organoleptic tertinggi terhadap warna, rasa, serta aroma daging buah.

The purpose of this study was to determine the effectiveness of ethanol vapor treatment and chitosan coating in slowing down quality deterioration and extending the shelf life of mangosteen fruit. Analysis used a factorial completely randomized design with two treatment factors. The first factor was giving ethanol vapor from the evaporation of ethanol solution with concentrations of 0%, 5%, and 10%; and the second factor was chitosan coating with concentrations of 0%, 1.25%, and 1.5%. The parameters were weight loss, the intensity of damage, color difference, fruit hardness, total acid value, total dissolved solids, and organoleptic tests on the color of the flesh, the flesh taste, and the flesh aroma.

Karakteristik dari briket hasil perlakuan S3L3 ini adalah memiliki kuat tekan sebesar 235.11 kgf/cm2, kerapatan massa sebesar 0.62 g/cm3, kadar air sebesar 1.67%, dan laju pembakaran sebesar 0.012 g/menit. \u0000Abstract \u0000Coffee 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 wate","PeriodicalId":400994,"journal":{"name":"Jurnal BETA (Biosistem dan Teknik Pertanian)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130525343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 bloom is the delivery of high-frequency sound waves in 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, Pakcoy was exposed to jazz music to determine the effect on production of Pakcoy, and the best length of exposure. The length of exposure to jazz music was 1 hour, 2 hours, 3 hours, 4 hours, and 5 hours starting from 07.00 WITA. The type of jazz music used was Jazz Rock with the musical instrument Gambandella by 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 – 2100 Lux. The results showed the length of 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 Pakcoy production.","PeriodicalId":400994,"journal":{"name":"Jurnal BETA (Biosistem dan Teknik Pertanian)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125278032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
