Abstract

Agrotourism has an important role in developing the economy and has been a source of job opportunities in the villages in Indonesia. Many BUMDes’ (Township and Village Enter-prises/TVEs) manage agrotourism as their core businesses. Meanwhile, most of them have experienced a turnover-declining during the Covid-19 pandemic and need new managerial strategies to survive this pandemic. Human resource holds a strategic function in this problem since most of the BUMDes recruits their employers locally since it is designed to reduce unemployment in the village while utilizing the resources possessed by their villages. Contrarily, the pandemic of Covid-19 has given a severe impact on agrotourism in Indonesia and has pushed BUMDes’ to cut their employer numbers for reasons of efficiency. This study aimed to describe the human resources management conducted by BUMDes during the Covid-19 Pandemic, employing a qualitative approach with the chairman and employees of BUMDes as the informants. Data from this research were analyzed by Miles and Huberman’s model. The research was held on agrotourism-based BUMDes in Malang and Batu. The results indicated that the BUMDes’ managers used the strategy of the temporary off-work system when the government implemented community activity restrictions (PPKM). During this off-work time, BUMDes did not pay their employees but gave a food package as social assistance to the workers. It proved that BUMDes was applying a social systems approach in managing their employees during the pandemic to hold its function as one of the economic pillars for villagers.

Abstract

Biological control is a long-term and environmentally friendly method of pest management. The use of biological control agents has several advantages. These advantages include limiting the growth and development of plant-disrupting organisms over a relatively long period. Furthermore, biological agents have advantages in maintaining the equilibrium of the ecosystem that is present in agricultural environments. Due to their ability to create antimicrobials and stimulate plant development, as well as the fact that they are plant growth-promoting rhizobacteria (PGPR) and can survive in adverse environmental circumstances, antagonistic bacteria are one of the biological or biocontrol agents for managing illness. Antagonizing microorganisms can boost plant resilience to disease attack without polluting the environment or leaving toxic residues in the food chain Bacteria with good antagonistic agent properties can prevent the growth of pathogens and stimulate plant resistance responses. In addition, antagonistic bacteria can simultaneously boost the growth response of plants (plant growth promoter). One of the antagonistic bacteria used as PPGF is Pseudomonas fluorescens. Pseudomonas fluorescens has been widely recognized as having the potential as a biological agent to inhibit several plant pathogens. P. fluorescensis a group of root bacteria that effectively suppresses various plant diseases, including damping off of seedlings, soft rot, bacterial wilt, and others on many plant varieties. An antibiotic substance produced by P. fluorescens. (2,4-diacetylphloroglucinol/ 2,4-DAPG) can increase soil resistance to pathogens.

Abstract

In Industry 4.0, where the internet and information technology have become primary needs, it is necessary to integrate information technology with the world of business and industry. The business world and industry need new skills. Higher Education, especially polytechnics as producers of expert workers, has not produced many graduates with competencies that are relevant to current conditions. Therefore, a curriculum is needed that can create graduates suitable for the needs of the business and industrial world. This research aims to design an integrated curriculum between business and industry that will be applied in the Applied Bachelor Program in Business Information Systems at the State Polytechnic of Malang. Qualitative research methods were used in this study, and literature studies and discussions were carried out with several industry curriculum experts and practitioners from the industry. The redesigned curriculum requires several analyses such as several data sources, namely curriculum evaluation which contains analysis from the previous curriculum, study materials or literature study and input from industry through tracer studies. The curriculum is made by paying attention to pedagogical learning and integrating industry, business and informatics. The redesigned curriculum also pays attention to the body of knowledge (BOK) by taking similar knowledge covering four main areas: information system strategy and management, information system development, operation, and evaluation of information system solutions. The results of this study are in the form of graduate profiles and a learning outcome matrix that is following the study material and the integration between business and informatics for applied undergraduate polytechnics.

Abstract

The State Polytechnic of Malang has created a learning system that uses gamification as one method to improve student motivation in their academic work. Massive Open Online Courses, or MOOCs for short, are one of the learning strategies used. They are open to everyone and offer online learning opportunities with no cap on the number of students who can enroll. Gamification has been implemented in the State Polytechnic of Malang MOOC system for teaching web programming design to overcome concerns with the online learning system. To make learning more interesting and motivating, the MOOC system implements the concept of gamification. Research and development (R&D) techniques were employed in this study to validate the gamification design process. The study was conducted using two types of scenarios to test the level of student motivation from the use of MOOCs. Using gamification and MOOC is a new phenomenon in open learning and is known as a good strategy di Independent Campuses. Gamification consists of the show that badges, leader boards, and performance graphs positively affect competence need satisfaction. The calculation of the change in motivation is obtained by the activeness of students in answering quizzes, uploading the results of the Job sheet, and claiming rewards in each activity. The reward is one of the important points in gamification that can be used as a parameter to increase student motivation in studying any given material.

Abstract

The COVID-19 disease first appeared in Wuhan City, Hubei Province, China. Until now, the disease was caused by the SARS-CoV-2 virus. This disease then spread to almost all countries and was declared a pandemic. One of the steps to prevent a wider spread is through vaccination. Acceptance of the COVID-19 vaccine has an important role in controlling the COVID-19 pandemic. The COVID-19 vaccine has a pretty good preventive effect, but its effectiveness really depends on the dose, disease severity, and type of COVID-19. Most people, including health workers, are not willing to receive the COVID-19 vaccine. The reason is the lack of knowledge and also the side effects of the vaccine, which affects the acceptance of the vaccine. The purpose of this study was to assess knowledge, perception and acceptance of the COVID-19 vaccine. This study uses a literature study approach and uses 4 review articles. Data were analyzed descriptively. The results of the analysis show that most people have insufficient knowledge about the COVID-19 vaccine. Perceptions of vaccines are also lacking because they feel unsure about the COVID-19 vaccine. Most health workers have good knowledge so that it is easier for them to accept the COVID-19 vaccine. The government needs to increase access to information about the COVID-19 vaccine so that people are willing to receive the COVID-19 vaccine.

Abstract

The arrangement of land systematically and in an integrated manner is an important effort to protect the watersheds. The Jatibarang reservoir in Kreo catchment area also have sedimentation problems, which can be a serious threat to the useful life of the Jatibarang reservoir. The purpose of this study was to analyze the trends of land cover changes in the Jatibarang reservoir watersheds from 1999 to 2020. The assessment of land cover changes based on Landsat 8 satellite image data of the reservoir watersheds area in 1999, 2003, 2010, 2013, 2015, 2018, 2020 collected from the https://earthexplorer.usgs.gov/. The analysis of land cover data using ArcGis Swat software. There was a slight decline of forest area from 1999 to 2010. That was due to the function changes off forest as paddy fields and built-up land. After 2010, there was a degradation of the forest area and paddy fields, followed by a fairly rapid increase in built-up land. The type of built-up land cover increased by ± 308% due to the rate of population growth which resulted in an increase of the need for housing and the growth of industrial area. A slight rate of forest reduction is caused by the needs to provide tourism-related land such as stalls, parking lots and additional tourist facilities. The garden area which decreased until 2010, gradually increasing from 2013 to 2020. This is related to the change in people's tendency to change their livelihood from farming to gardening. It was also observed that in 2020 the waters of the Jatibarang reservoir had decreased. These results indicate that there has been a change in the function of the Jatibarang reservoir land for the needs of the surrounding community.
