Financial Impact Analysis of Carbon Pricing on Geothermal Power Plant Project Investment at PT PLN (Persero)

/in /by

Climate change is a significant global challenge, mainly driven by greenhouse gas (GHG) emissions. The energy sector is a major contributor to GHG emissions, accounting for approximately 73% of global emissions in 2022. Within the energy sector, electricity emitted 13 GtCO2 or contributes approximately 35% of global emissions related to energy. To address this challenge, PLN, a state-owned electrical utility in Indonesia, has declared a roadmap to achieve Net Zero Emissions by 2060. The company has also implemented some strategic initiatives to achieve the goal. Carbon pricing is one of the key efforts that enable PLN to receive incentives for reducing GHG emission while also enhancing financial performance.

/in /by

This research addresses the critical business issue of optimizing staffing levels and streamlining personnel budgeting within WIKA through the standardization of job descriptions and the determination of optimal personnel numbers. The study, driven by three key research questions, involved analyzing data from 26 medium-scale projects using Lean Office tools and Workload Analysis formats. Standardizing job descriptions led to a significant reduction in redundancies, with the Commercial section decreasing from 81 to 74 roles, Engineering from 37 to 21, and Finance & HC from 34 to 24. Optimal staffing levels were established by validating average working times with expert judgment, resulting in a more efficient allocation of human resources. This optimization saw the Finance & HR team reduce from 6 to 5 employees, Engineering from 9 to 8, and Commercial from 6 to 5, increasing individual work times and ensuring alignment with operational needs. Proper budget standards for personnel costs were developed by comparing historical and current data, leading to significant cost savings: Rp 243.69 million in Finance & HC, Rp 213.91 million in Engineering, and Rp 127.02 million in Commercial. These findings demonstrate that WIKA can enhance its operational performance and efficiency by implementing standardized job descriptions, optimal staffing levels, and accurate budget standards. Recommendations include adopting these standards across all medium project classifications and maintaining regular reviews to ensure continuous improvement, ultimately supporting sustainable growth in the construction industry.

Estimation of Polyphenol and Antioxidant Content from Papaya (Carica papaya) and Mango (Mangifera indica) Seed, Peel and Leaves

/in /by

Papaya (Carica papaya) and mango (Mangifera indica) are two tropical fruits which are widely known for their rich nutritional properties and various health benefits. Papaya belongs to family Caricaceae which has its origin in South Mexico. Mango belongs to the family Anacardiaceae and were originated from India and southern China. As the pulp of these fruits is known to be consumed rapidly while their seeds, peels and leaves are often thrown away as waste. This study involves the estimation of total polyphenol and anti-oxidant activity of the by-products of papaya and mango fruits. The anti-oxidant activity by DPPH method of % inhibition of papaya seed=180 peel=125 leaves=64 is higher compared to mango by-products. In FRAP, ABTS, Radical Cation method of mango samples shown higher levels than papaya. Vitamin c content of mango seeds exhibits high as 15.6mg/100g compared to papaya seed, papaya peel and leaves has higher levels of vitamin c compared to mango peel and leaves. The total polyphenol activity (GAE/g) of mango seed=118.4, peel=55.31, leaves=19.04 exhibits higher value compared to papaya. Papaya seed and peel has more beta carotene content compared to mango whereas mango leaves shown more beta carotene content than papaya. Seeds of papaya and mango has 2.05% and 2.15% pectin, mango peel has more pectin content than papaya 12.45%>8.94% and mango peel has shown slightly more pectin content than papaya as 4.25>3.58. Papaya peel have medium number of abundances of tannin content, seeds and leaves have less in number whereas mango have equal amounts of abundance of tannin content. This study mainly features the importance of the bioactive compounds found in the by-products (seed, peel, leaves) of papaya and mango and their health benefits.
