<em>The background of this research is the occurrence of the COVID-19 pandemic in the world, including in the Landak Regency, West Kalimantan Province. Various efforts had been made by the government, religious institutions, and traditional institutions. Dayak traditional institutions in Landak Regency and all traditional administrators in various Dayak villages in Landak Regency carried out Balala' traditional rituals to prevent transmission. The purpose of this study was to describe the perceptions and reasons for the Dayak indigenous people to carry out the Balala' ritual concerning efforts to prevent the transmission of the COVID-19. This study used a qualitative method, where data was taken by observation, literature study, and interviews. Interviews were conducted by going down the field and also interviews via WhatsApp. The data analysis technique used an interactive model. The results showed that the Balala' ceremony which was held by the Kanayatn Dayak people in the Landak Regency of West Kalimantan, was believed by those who attended it to be able to free them from the attack of this COVID-19 outbreak, because of three things, namely: (1) they had invited Jubata to come on during the Balala' ritual so Jubata would protect them; (2) The traditional Balala' ceremony is in line with the government's call for social distancing; and (3) those who had been Balala' are clean so that the COVID-19 virus cannot enter them. This research needs to be continued especially to see firsthand the effectiveness of the traditional Balala’ ceremony on the transmission of the Covid-19 and the impact of this pandemic on the social, cultural, and economic life of the Dayak indigenous people.</em>

<em>This study aims to determine the interaction effect of the type and dose of Trichoderma sp. and its secondary metabolites on suppression of Fusarium sp. wilt disease and its effect on the growth of tomato plants (Solanum lycopersicum mill.). This study used a Randomized Block Design (RBD) which consisted of two factors. The first factor is the type of application (J) which consists of three levels of treatment, namely: J1 = Trichoderma sp., J2 = Secondary metabolites. J3 = Trichoderma sp. + Secondary metabolites, while the second factor is the application dose (D) which consists of three treatment levels, namely: D1 = 10 ml/plant, D2 = 20 ml/plant, D3 = 30 ml/plant. The treatment was repeated 3 times to obtain 81 tomato plants and added 9 control treatment plants. The parameters observed were the percentage of wilt disease, plant height, stem diameter, number of leaflets, and number of branches. The results showed that in laboratory testing, the mushrooms Trichoderma sp. and secondary metabolites can inhibit the growth of the mushrooms Fusarium sp. In research in the field, treatment with Trichoderma sp., secondary metabolites, and Trichoderma sp. + secondary metabolites, with various spore densities and applied 7 days before planting can reduce the wilting percentage to 0%. The interaction treatment of type and application dose had a very significant effect on the number of leaflets, and had a significant effect on stem diameter but had no significant effect on plant height and number of branches. The highest results on the variable plant height and number of leaflets were found in the J3D3 treatment with a height of 82.67 cm and a number of leaflets of 85.11 strands. The highest results on the stem diameter variable were found in the J1D3 treatment with a diameter of 6.59 mm, while the variable number of branches was found in the J3D1 treatment with 1.35 branches.</em>

<em>The study aimed to investigate the impact of employee engagement on performance at a South African pump supplier. The research adopted a qualitative study and a non-probability purposeful sampling technique with a target population of ten employees at the company. It examined the factors that contributed to the development of employees’ engagement and the effect of engagement on employee performance. The research instrument used interview and was analyzed qualitatively. Key findings revealed that the employees at the company are disengaged due to ineffective leadership, poor communication between management and employees, lack of a recognition system, inadequate employee participation in decision-making, and an absence of a strategic and coordinated approach to the employees’ well-being. Recommendations were that the organization should allow its workforce to provide input in the decision-making of the organization, improve effective and transparent internal communication, employee development and empowerment, and an effective recognition system. Leaders should support the effective utilization of employee skills and capabilities. The study showed that there is a relationship between employee engagement and performance due to the lack of employee engagement that lowered employee capability and affected the organization's bottom line. Designing and implementing an effective employee engagement strategy is, therefore, desirable to the employee and organizational performance.</em>
