Therefore, the purpose of the current paper is to get efficiency best by using biodiesel fuel and comparative with normal fuel. The variables under consideration include biodiesel ratio, engine load, and injection pressure. The experiments were performed with different engine speeds (1500, 2000, and 2500 rpm) and with different torques (4, 5, 5, 7, and 8 N.m). The biodiesel ratio (at 10%, 20%, and 30%) affects engine performance, power, specific fuel consumption, and mean effective pressure. The comparison is performed in the previous variables according to the gas ratio of the output exhaust (NOX, CO2, CO, HC, and smoke). The experimental work shows the center composite design approach of the response surface methodology. To get the best performance from the engine, the optimal values for the engine factors are 50% per volume, an engine speed of 2500 rpm, and an engine torque of 5.9744 Nm. The optimal engine performance responses depending on these optimal factors have been Power (KW) 2.36665, BMEB (bar) 3.6465, BSFC (g/kWh) 338.131.

Therefore, the Nipa habitat develops into an area of water mass circulation and becomes rich in nutrients that trigger the growth of phytoplankton as the primary producer in the aquatic ecosystem. This study aimed to examine the species composition and distribution of phytoplankton and nutrient content in the nipa ecosystem on the west coast of Aceh, Indonesia. It was conducted from July 2018 to September 2019 and sampling was carried out in two areas, namely Kuala Bubon Aceh Barat district and Kuala Tadu, Nagan Raya district. A total of 100L of surface water samples was taken from three points at each location. Subsequently, the water was filtered with a plankton net mesh No. 25 and preserved with a 4% Lugol solution. The water sample from both locations was also analyzed for nitrogen and phosphorus contents. The results showed that there were 20 species of phytoplankton in both sampling locations, with Kuala Bubon consisting of 13 species with density of 160.87 cells L-1, and 15 species in Kuala Tadu with density of 273.64 cells L-1. Haramonas sp. was the dominant species in Kuala Bubon, while Amphisolenia bidentata was dominant in Kuala Tadu. Based on the nutrient content (nitrate+nitrite and phosphate), the average nutrient content in Kuala Bubon was 1.31 mg L-1 (mesotrophic) and 0.12 mg L-1 phosphate (hypertrophic). Meanwhile, Kuala Tadu had 1.078 mg L-1 nitrate+nitrite (mesotrophic) and phosphate, 0.22 mg L-1 (hypertrophic) waters. These findings are an early indication that the estuary of Kuala Bubon and Kuala Tadu have been contaminated by organic matter.","PeriodicalId":39816,"journal":{"name":"International Journal of Design and Nature and Ecodynamics","volume":"172 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79468301","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}

Researchers were studying the water recycling technique and finding about other possible renewable water resources for irrigation, they conclude that saline water can be used to meet part of the irrigation water needs for many crops under special field management, because there are many crops have a high tolerance to the salinity without decreasing in the yield. The current study aims to evaluate the economic yield of saline drainage water in irrigation. A computer program (Fıuat Ujaj) using Visual Basic language was constructed to use the largest possible amount of drainage water for irrigation after removing the toxic effects and then calculates the relative yield of the selected crops. The Main Outflow Drain (MOD) in Iraq was selected as a saline water resource which has 4.63 dS m-1 Electrical Conductivity (EC). This saline water contained high concentrations of chlorine and sodium ions. MFUP results showed that toxic effect of these ions can be removed by diluting with 35% of the nearby river water. MFUP results showed that the crops with high and medium tolerance to salinity give an acceptable yield ratio when they were irrigated with diluted water (35%) to remove toxicity effects only, while the dilution increases for crops of medium sensitivity, but the acceptable yield of sensitive crops is not achieved except with fresh river water. If the crop production is lower than the economically acceptable limit, another 5% of the river water will be added to mitigate, and the dilution process continues until the percentage of the river water become 80% of the irrigation water. If the required product is not achieved, then the program instructs to irrigate this crop with the river water only.","PeriodicalId":39816,"journal":{"name":"International Journal of Design and Nature and Ecodynamics","volume":"41 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74384103","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}
