The study encompasses both Junior High School (JHS) and Senior High School (SHS) students, as well as educators, aiming to comprehend their viewpoints. Through the utilization of surveys with varying response alternatives, the research discovers that JHS students hold diverse opinions, whereas a greater percentage of SHS students (27% showing strong agreement and 30% expressing agreement) associate these tasks with a reduction in their interest. Conversely, a significant majority of teachers (75%) strongly concur that such punitive measures undermine students' motivation. This accentuates the necessity for captivating teaching approaches in agricultural education, with the objective of igniting authentic interest and cultivating positive experiences among students. In essence, the article underscores the detrimental effects of utilizing agricultural tasks as disciplinary actions on students' inclination toward agricultural studies and suggests implementing more engaging teaching methods to foster genuine enthusiasm and favourable learning encounters in this field.","PeriodicalId":153770,"journal":{"name":"The International Journal of Science & Technoledge","volume":"52 13","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139007060","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}

Many factors contribute to the success of mobile money transfer systems, and usability measures the level of success. Usability heuristics principles developed by Nielsen, a pioneer in usability engineering, have existed and are popularly used to assess the usability of computer systems. However, in the wake of emerging new technologies such as mobile applications and mobile money transfer systems, there is a need for domain-specific heuristics.    The purpose of the study is to investigate the usability of mobile money transfer systems and develop a usability heuristic framework that enhances Mobile Money Transfer Systems.   The study covered mobile money transfer systems in Kenya. The research adopted a mixed method design that included the Design Science Research methodology and survey design. The Design Science Research process provided the structure for the study and the survey design guided the questionnaire administration. Data were obtained using questionnaires. The target population was Mobile Money Transfer System consumers in Nairobi County, Kenya. The data collected was analysed using both descriptive and factor analysis. A mobile money transfer system usability heuristics framework was developed using the findings. A sample of 396 was used, with a response rate of 81.1%. This framework was validated by mobile money transfer systems experts, who agreed that the developed framework can be applied in the real world with an average weighted mean of 4.55, allowing for further development. This research contributes to knowledge of usability heuristics required to evaluate mobile money transfer systems, reducing the development time and cost.","PeriodicalId":153770,"journal":{"name":"The International Journal of Science & Technoledge","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139314282","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 vegetable contributes about 31.8% to domestic horticulture and is ranked in the following order: Kales, Cabbages, Tomatoes, Cowpeas, Spider plants, Snow peas, Nightshade and Amaranth. Tomato fruits can be used as salads, cooked as vegetables, processed into tomato paste (puree), tomato sauce, ketchup, juice and sun-dried tomato. This study only analysed tomato fruits and did not study the products of tomato fruits. Tomato production is grown in most of the agro-ecological zones in the country. There is a high demand for tomato consumption in the country because every household uses tomato and the performance of tomato production could depend on the production system in place. There are two production systems, the open field and the protected environment system (greenhouse technology or screen house technology) and the two production systems have different performance potential. The greenhouse technology is only 10% adoption rate and the open field technology is 90% adoption rate. The greenhouse technology supposedly produces more up to tenfold compared to open field technology. The open field technology and the greenhouse technology use the determinate and indeterminate tomato varieties, respectively. This study, therefore, purposed to determine the profitability level of the two tomato production systems in Kenya. The study used documents from Horticulture Development Authority, Kenya Agriculture Livestock Research Organization, Amiran Kenya Limited and Ministry of Agriculture, Livestock and Fisheries. Partial budgeting analysis and Breakeven analysis were used to determine profitability. The net return obtained for using equivalent greenhouse technology over the open field technology in one acre of land was Ksh 1,328,320 in one production season. The average net return was Ksh 127,478 per greenhouse technology in one production season. There was also an average net return of Ksh 127.5 per plant. The Breakeven analysis in greenhouse technology was 335,010.137 kgs of Tomatoes in one production season. The Breakeven analysis in greenhouse technology per one greenhouse was 32,150.685kgs of tomatoes. Therefore, only 1.6 production seasons are required to breakeven. Thus, it can be concluded from the study that it is economically worthwhile to use greenhouse technology in tomato production in Kenya.","PeriodicalId":153770,"journal":{"name":"The International Journal of Science & Technoledge","volume":"343 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139341554","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}

Specific sampling techniques are used for specific research problems since one technique may not be applicable to all problems. Similarly, if the sample size is inappropriate, it may lead to an erroneous conclusion. The complexity of a study population determines the sampling strategy to be used.

This is usually carried out by the addition of small quantities of some water-soluble colloids or creaming agents. Such include ammonium alginate, sodium alginate, sodium cellulose glycollate, methyl cellulose, aluminum cellulose glycollate, pectins, extract of carragheen moss, glue, gelatine, gum Arabic,  gum acacia  Senegal, locust bean gum,  gum tragacanath, tamarind  Kernel Powder, gum  Karaya, and Polysaccharides such as maize,  sorghum, rice, yam, potato starch and cassava starch. Many of such creaming agents are made from chemicals that are finite, imported, and therefore very expensive and some are toxic to human health and wellbeing. The production of such chemicals leads to a lot of environmental pollution and its attendant degradation and health virus, not to mention their exorbitance. These imported creaming agents are now beyond the reach of smallholder farmers and cottage industrialists. The use of vegetative creaming agents such as locust bean, polysaccharides, tamarind kernel powder, etc. has been reported and practiced and the results have been very good and encouraging (BIS 2001, Blackley, 2010). Fresh, natural rubber latex (FNRL) (with 40% rubber and 60% water) can be processed into concentrated natural rubber latex (CNRL). This is done to meet industrialists' demand, increase its economic value, increase its dry rubber content (DRC) and ease transportation costs. Also, dipped goods usually require a high concentration of DRC and purification too. Products such as hand gloves, condoms, balloons, pillows, mattresses and suckers, teats, and catheters are usually made from concentrated latex. Methods such as centrifugation, evaporation, electro-decantation and creaming are the methods used for purifying and concentrating FNRL. However, due to the cost of most chemicals imported into the country and the high cost of machines also imported, many entrepreneurs have tried to develop green rubber processing methods. These methods do not require the use of big bogus expensive machines. The main object of this project is to develop a system to prepare cream-concentrated natural rubber latex (CNRL) without using sophisticated machines and importing expensive chemicals. We will work on a simple, cheap, green, environmentally and health-friendly method to produce cream CNRL. The main parameters of the cream CNRL such as DRC, Total Solids Content (TSC), Volatile Fatty Acids (VFA), Alkalinity and mechanical stability time (MST) of the cream CNRL, would be tested and evaluated. The use of vegetative creaming agents like those listed above has long been practiced and reported Tamarind kernel powder (TKP) and Cassava Processing Effluents powder (CPE) would be used as the dual or joint creaming agents in a synergy.","PeriodicalId":153770,"journal":{"name":"The International Journal of Science & Technoledge","volume":"58 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139349438","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}
