So we need a method to determine the rate of respiration (CO2 production), one of which is the Arrhenius model. The purpose of this study was to predict the CO2 production rate of Barangan bananas using the Arrhenius model. CO2 production of Barangan bananas with different harvesting ages (10 and 11) weeks was measured using the Continuous Gas Analyzer IRA-107 Shimadzu where the banana samples were placed in a respiration chamber, refrigerator for low temperature storage. The measured respiration rate data was then estimated using the Arrhenius model. When the storage temperature increases, the rate of CO2 production will increase. At the harvest age of 11 and 10 weeks the higher the storage temperature, the CO2 production rate will increase. The relationship between CO2 production rate and storage temperature can be solved using the Arrhenius model. The results of the prediction of the Arrhenius model found a coefficient of determination of 0.91-0.94. The k values of 10 weeks of harvest (0.1, 0.24, 0.36) and k of 11 weeks of harvest (0.19, 0.31, 0.49) were calculated using the equation obtained using the Arrhenius model. Value of Ea harvested 33.76 kJ/mol at 10 weeks and 45.83 kJ/mol at 11 weeks. The respiration rate produced at 10 and 11 weeks was different, where the CO2 production rate at 11 weeks at harvest was 77.98 ml/kg.hour with predicted results of 75.76 mm/kg.hour and at 10 weeks at harvest 65.80 ml/kg.hour with a predicted result of 68.21 ml/kg.hour. The results of the Arheniuss model can be used to estimate the CO2 production rate of Barangan bananas during storage","PeriodicalId":276781,"journal":{"name":"Jurnal Agrotek UMMat","volume":"9 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120917691","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 Global Hunger Index said that the level of hunger in Indonesia is at a serious level but processing food waste can have a positive impact on the family economy. This study first aims to determine the factors that influence the behavior of preparing food, secondly to determine the factors that influence the behavior of wasting food, and thirdly to find out that food waste can improve the family's economy. This type of qualitative descriptive research was carried out in Jiken Village, Tulangan District, Sidoarjo Regency, East Java purposively using primary and secondary data. Data were taken by sampling with household interviews and analyzed to obtain answers to the research objectives. The results showed that the behavioral factors of the household preparing food include the number of family members, planning to prepare food, the amount of food preparation costs, the intensity of cooking a day, and whether or not they have ever learned to cook. Factors that influence household behavior in disposing of food include inappropriate menus, number of menus, schedule of eating more than twice a day, appearance of ordinary food, and inappropriate taste of food. Food waste can improve the family's economy, namely 60% food waste can be used to animal feed. It is hoped that this research method will produce patterns of household behavior in preparing food and reducing the amount of food waste and the family economy will increase from food waste processing.","PeriodicalId":276781,"journal":{"name":"Jurnal Agrotek UMMat","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130411836","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}

This study aimed to determine the best sterilization time for catfish’s asam pedas using retort pouch packaging based on physicochemical and microbiological characteristics. The sterilization time used is 5, 10, 15, 20, and 25 minutes. Parameters observed were fat, protein, pH, thiobarbituric acid (TBA), texture, and Total Plate Count (TPC). The results showed that the sterilization time did not affect fat content, protein content, hardness level, TBA value, and the number of microbes, but the sterilization time significantly affected the pH value of catfish’s asam pedas packaged in retort pouches. Overall, the sterilization process carried out in this study did not change the physicochemical and microbyological characteristics of the catfish’s asam pedas. The best treatment in this study was a sterilization time of 25 minutes with a TPC value of 6.14 x 106 CFU/ml, the protein content of 11.89%, the hardness level of 178.81 gf, the pH value of 6.11, the fat content of 6.27%, and the TBA content of 0.19 mg malonaldehyde/kg.","PeriodicalId":276781,"journal":{"name":"Jurnal Agrotek UMMat","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133315863","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 object of this research is agricultural pollinating insects, namely Butterflies. The research was carried out from literacy studies of journals, books, scriptures, and electronic media. The methodology used is descriptive analysis. The methods used include reflexivity, dynivity, and similarity. The results obtained that the Butterfly motif stores codes R12 and R47 which are the unification of religion and science. There is a natural morphology on the butterfly's upper wings in the form of seven individual lines (7). The bottom wing motif shows a pattern of three (3) small circles like the letter sin, there is also a protrusion of the inner wing that has a long motif with the pattern of the number one (1) like the letter lam, and the largest circle pattern with the number nine (9) on the inside like the letter mim, so it looks like 319 and sinlammim. The source of my reflexivity comes from the R12 which is positioned at the bottom. The number 19 out of 319 is also found in Covid-19 which has an economic impact. The butterfly carries the message of the formula resulting from the structure of creation on the wings with the Hahslm 472319 pattern. This formula gives the meaning of dynivitas (unification) in the Butterfly that religion and science are one unit. Besides that, there is also meaning in the life of a pandemic in the form of a link between the existence of butterflies that the agricultural process is carried out in a worship way through insects with a wing motif which shows that humans turn to God for worship. The novelty of this research is that the dynivtas formula stored in the butterfly's wings can be used as a lesson in agricultural ecosystems in the current pandemic economic era.","PeriodicalId":276781,"journal":{"name":"Jurnal Agrotek UMMat","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130826495","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}
