The research use qantitative method. The sampling method adopted is purposive sampling. The analytical techniques encompass descriptive statistics, normality tests, multicollinearity tests, heteroscedasticity tests, autocorrelation tests, multiple linear regression analysis, coefficient of determination tests, F tests, and T tests, all conducted using SPSS 25 for Windows. The findings indicate that firm size and total asset turnover positively and significantly influence profitability, whereas leverage has a significant negative impact on profitability. Surprisingly, liquidity was found to have no significant effect on profitability. These results suggest that there is room for improvement in the management of company assets, highlighting the need for companies to focus on enhancing their asset management capabilities to foster sustained growth.

Abstract

This study aims to determine the effect of the addition of Organic Fertilizer (OP) made from oil palm plantation waste and cow dung enriched with Agricultural Symbiotic Microbes (ASM) on Sorghum (Sorghum bicolor) production. This research was conducted in Natai Raya Village, Kumai District, West Kotawaringin Regency, Central Kalimantan. The design used was Randomized Complete Block Design (RCBD) consisting of 4 treatments P0= control (100% NPK fertilizer), P1= NPK fertilizer 100%+OP 50% (100 g/plant), P2= NPK 100%+OP 100% (200 g/plant), P3= NPK 100%+OP 150% (300 g/plant). The number of sorghum per plot was 24 plants, and the number of plots per treatment was 3 plots, with a size of 3x2 m (6 m2). Harvesting age of sorghum was 70 days. Parameters observed: plant growth (plant height and number of tillers), and plant production (fresh weight and dry matter). The results showed that the average height of sorghum plants were:  P0 = 181.14 cm, P1 = 204.35 cm (increased 12.81% compared to PO), P2 = 211.81 cm (increased 16.93%), and P3 = 218.79 cm (increased 20.79%). The number of tillers of sorghum plants were: P0= 10.47 stems, P1= 10.53 stems (increased 0.53%), P2= 10.74 stems (increased 2.52%), and P3= 11.01 stems (increased 5.1%). The fresh weight production of sorghum plants and fruits per plot was P0= 13.4 kg or 22.36 tonnes/ha, P1= 17.1 kg or 28.52 tonnes/ha (27.55% increase), P2= 17.5 kg (30.63% increase) or 29.21 tonnes/ha, and P3= 18.2 kg or 35.75 tonnes/ha (35.75% increase). The dry matter production of sorghum plants and fruits per plot were P0= 4.17 kg or 6.94 tonnes/ha, P1= 5.31 kg or 8.85 tonnes/ha, P2= 5.44 kg or 9.07 tonnes, and P3= 5.66 kg or 9.43 tonnes/ha. The conclusion of this research is that the addition of organic fertilizer as much as 150% or 300 g/plant gives the best results on the growth and production of shorghum plants.   Keywords: Growth, Production, Shorghum, Organic Fertiliser, Oil palm plantation waste and cow feces.

Abstract

Introduction: Since the first case of COVID-19 was detected in Indonesia, the government has implemented Large-Scale Social Restrictions to control the spread of the disease. However, these restrictions have had a negative impact on the economy. To address this, the government has introduced a new normal policy to restore activities while managing the risk of transmission. The government has adopted WHO guidelines through Minister of Health Decree No. 238 of 2020 to ensure COVID-19 workplace safety. This article aims to explore the barriers to COVID-19 workplace safety among Indonesian office workers. Methods: This qualitative research was conducted in DKI Jakarta and Surabaya from September to October 2020. In-depth interviews and observations were conducted with 22 informants selected purposefully. Thematic analysis was used, drawing on the Social-ecological Model (SEM) theory. Results: At the intrapersonal level, fear and perception barriers impact preventive actions against COVID-19. At the interpersonal level, peer influence and perceptions of the work environment affect adherence to office policies. At the organizational level, employee behavior is influenced by socializing, rules, and workplace amenities. Lastly, public policy enforcement is vital at the macro level to reduce risky behaviors among office workers. Conclusion: Implementing comprehensive protocols across different levels is crucial to creating COVID-19 workplace safety. This requires increased public awareness and consistent enforcement, including strengthening organizational policies.
