Arrowroot tuber plants have the potential to adapt well to various environmental conditions including water stress. The aim of this research was to identify the effect of water stress on yield production (number, weight, length and diameter) and evaluate the nutritional content of arrowroot tubers. This research used a Completely Randomized Design (CRD) with 7 water stress treatments, namely (P1) 15 days of waterlogging, (P2) 10 days of waterlogging, (P3) 5 days of waterlogging, (P4) daily watering, (P5) watering every 5 days, (P6) watering every 10 days, and (P7) watering every 15 days which was repeated in 2 experimental repetitions and 2 measurement repetitions. The results of the research showed that there was no decrease in yield in treatments P1 to P3, however in treatments P6 and P7 there was a difference in the yield of lower tuber weight compared to the daily watering treatment (P4) and the once every 5 days watering treatment (P5). Treatment The results of proximate analysis of arrowroot tubers with the best yield production (P5) showed that the water, ash, fat, protein and carbohydrate content of fresh tubers were respectively 69.82%, 1.47%, 0.21%, 0, 45% and 28.15%, while arrowroot flour is 2.28%, 4.77%, 0.33%, 1.47% and 91.16%. The results of this research provide information that arrowroot plants can be planted on land that has the potential to be flooded during the arrowroot growing season, but arrowroot plants require sufficient water to optimize their production. The high carbohydrate content of arrowroot tubers reflects its potential as an alternative food source to replace wheat and rice.","PeriodicalId":198121,"journal":{"name":"Journal of Global Sustainable Agriculture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139176908","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}

UHI is a form of local climate change which is characterized by an increase in temperature reaching 6oC in central urban areas compared to vegetated areas on the outskirts of the city. Compact vegetated land or Green Open Space (GOS), which is able to avoid increasing the surrounding temperature. GOR H. Agus Salim as one of the GOS in Padang City is a place for residents to have recreation and fill their free time by enjoying various culinary delights with friends and family as well as sports activities. This research aims to measure the benefits of tree canopies as climate amelioration in the H. Agus Salim GOR area. The research was conducted in September 2023, with 7 repetitions at 5 measurement points (3 under the tree canopy and 2 in the open field). Data is measured directly in the field with a thermohygrometer. The cooling effect provided by trees was analyzed using a difference approach between measurements in shade and open areas. Thermal comfort level is measured using the empirical formula Temperature Humidity Index (THI). The results showed that there was a decrease in temperature under the tree from 2,0oC (in the morning) to 2,9C (in the afternoon). However, THI calculations show that GOR H. Agus Salim is in the Uncomfortable criteria both under a canopy and in open areas.","PeriodicalId":198121,"journal":{"name":"Journal of Global Sustainable Agriculture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139177048","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}

PT Amboja Global Lestari is a producer of hydroponic-based green lettuce. There is competition from green lettuce producers in Yogyakarta province and surrounding areas which significantly affects the sales level of PT Amboja Global Lestari's hydroponic green lettuce, so it is necessary to plan a strategy to be able to win the competition. The purpose of this study is to identify internal and external factors of hydroponic green lettuce marketing, analyze alternative marketing strategies, and determine the priorities of hydroponic green lettuce marketing strategies. The basic method of research uses a descriptive method with a qualitative approach. The data analysis method uses IFE Matrix, EFE Matrix, IE Matrix, SWOT Matrix, QSPM. The results of data analysis show internal factors that are the company's main strength in marketing hydroponic green lettuce, namely, quality green lettuce products, good service to consumers, guaranteed product quality guarantees to consumers, and online and offline promotions and sales are running well, with the highest score of 0.31, while for the main weakness, the distance to the hydroponic garden is quite far with the lowest score of 0.09. The main external opportunities are high consumer demand for vegetables, and there are often exhibitions with a score of 0.35, while the main threats are, the increase in new competitors, effective competitor marketing online and offline, and disease and fungal attacks, with a score of 0.21. IE Matrix Analysis shows that the company is in a position to grow and develop. The SWOT Matrix Analysis resulted in six alternative marketing strategies. QSPM analysis resulted in the main strategy priority of hydroponic green lettuce marketing, namely, increasing the quality and quantity of hydroponic green lettuce with a total TAS value of 7,615.","PeriodicalId":198121,"journal":{"name":"Journal of Global Sustainable Agriculture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130964310","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}
