However, the lack of irrigation water is not an obstacle in cultivation if the right, effective and efficient irrigation method is applied, namely drip irrigation. This study aims to see the effect of applying drip irrigation techniques with different water discharge treatments on tomato plant growth. This research was conducted in Batu Putik Village, East Lombok Regency from August 12, 2020 to September 20, 2020. This research method uses experimental methods by conducting direct experiments in the field. This study used a Completely Randomized Design (CRD) with 3 treatments 4 times repeated so that 12 experimental units were obtained. Each treatment was P1 with a 90° tap slope discharge, P2 with a 45° tap slope discharge, and P3 with a 15° tap slope discharge. The research data were analyzed using ANOVA. The results of the drip irrigation technique design performance test showed an average uniformity coefficient percentage of 94% in all treatments. The results of this test provide an insignificant effect on plant height, stem diameter, and number of leaves of tomato plants. So this insignificant result shows that the application in the field in relation to water efficiency should use P1 with less water distribution but gives the same effect as P2, and P3 on tomato plant growth. While in wet and dry stems, there is a significant effect between treatments.","PeriodicalId":276781,"journal":{"name":"Jurnal Agrotek UMMat","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132054726","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}

{"title":"Modeling multiple linear regression analysis in the formation of biogas pressure","authors":"B. Basirun, Ristu Haiban Hirzi, Muanah Muanah","doi":"10.31764/jau.v10i3.16302","DOIUrl":"https://doi.org/10.31764/jau.v10i3.16302","url":null,"abstract":"Fossil energy reserves to date are dwindling inversely proportional to the amount of consumption. So to overcome this problem, alternative energy is needed, one of which is biogas which is sourced from organic waste. The biogas production process has so far experienced many obstacles so that the formation of pressure has not been optimal. The aim of the research was to create a model to see the magnitude of the influence of humidity and temperature on the pressure of the biogas produced. The method used is multiple linear regression with the following stages, identifying variables, testing classical assumptions, model building, and model goodness. Based on the results of the analysis, the model Y ̂=17.029-0.042X_1+3.480X_2 is obtained. Simultaneous test results show that simultaneously humidity and temperature have a significant effect because the sig is 0.000<α(0.05). The results of the partial test (T-Test) of each variable also showed significant results on biogas pressure because the sig was 0.000<α(0.05). The coefficient of determination of 0.8180 means that humidity and temperature variables affect the formation of biogas pressure by 81.80% and the rest is influenced by other factors such us pH, C/NRatio, starter, and so on.","PeriodicalId":276781,"journal":{"name":"Jurnal Agrotek UMMat","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116206904","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}

Apart from being a food and vegetable, pumpkin can be processed into semi-finished flour which becomes a processed product. This study aims to examine the effect of sodium tripolyphosphate (STPP) concentration on the physical and chemical properties of modified pumpkin starch (Modified cucurbita moschata starch). This study used an experimental method in the laboratory with a completely randomized design (CRD). The concentrations of STPP used in the treatments were 0.1%, 0.3%, 0.5%, 0.7%, and 0.9% of the weight of pumpkin starch. Each treatment was repeated 3 times, totaling 15 experimental units. Parameters observed included solubility, swelling power, moisture content, and starch content. Data were analyzed using analysis of variance (Anova) with a real level of 5% and Least Significance Different (LSD) further test. The results showed that STPP concentration had no significant effect on solubility and swelling power, but had a significant effect on the moisture content and starch content. The higher the STPP concentration, the higher the water content and the lower the starch content. The 0.9% STPP concentration had the highest moisture content (15.54%) and the 0.3% STPP concentration had the highest starch content (92.63%).  In order to be more complex, further research is carried out to test the parameters of phosphate content, ash content, amylose content, amylopectin content, color, PH, viscosity, anthocyanins, crude fiber, gelatinization, syneresis, antioxidants, polyphenols, reducing sugar, water holding capacity and oil holding capacity.","PeriodicalId":276781,"journal":{"name":"Jurnal Agrotek UMMat","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127400707","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 fertigation used in this study were Smart Watering Unpad and Autopot with the parameters observed were ambient temperature, dissolved oxygen, and the relationship between ambient temperature and Dissolved Oxygen for 30 days of observation. The results showed that the response of dissolved oxygen levels was influenced by environmental temperature in the SWU 01 Lettuce, SWU 02, SWU 03, and SWU 01 Paprika systems had a NEGATIVE relationship direction. The Autopot system is the only installation that has a POSITIVE change in the relationship of dissolved oxygen levels influenced by ambient temperature. Autopot is a hydroponic installation that can maintain the availability of dissolved oxygen levels in the nutrient solution.

One type of plant that is often used is ginger rhizome and horse whip leaves. The purpose of this research is to formulate horse whip leaves and fresh white ginger rhizomes as herbal drinks to support functional food diversification. In this herbal drink making research using a one-factor Completely Randomised Design (CRD) method, namely a mixture of horse whip leaves and fresh white ginger whose treatment consists of P1 = Horse Whip Leaves 90%: Fresh White Ginger 10%, P2 = Horse Whip Leaf 70%: Fresh White Ginger 30%, P3 = Horse Whip Leaf 50%: Fresh White Ginger 50%, P4 = Horse Whip Leaf 30%: Fresh White Ginger 70% and P5 = Horse Whip Leaf 10%: Fresh White Ginger 90%. Data were analysed using analysis of variance (ANOVA) at the 5% level in Microsoft Excel and IBM SPSS Statistics 25.0 applications and if significantly different data are obtained, further tests will be carried out using Honest Real Differences (5%). It was found that the combination of horse whip leaves and fresh white ginger on the herbal drink produced did not have a significant effect on the organoleptic characteristics of aroma and taste scoring tests but had a significant effect on colour parameters. For the organoleptic quality parameters of herbal drinks, it is known that the treatment has been produced in the scoring test with the highest value of colour in treatment P1 (yellow), aroma in treatment P2 (ginger-scented) and taste in treatment P3 (slightly warm ginger).
