Heru H., Tanbiyaskur T., An-Nisa, S., Amelia, A., Adinda, O., Khairunnisa, R.,  Prihartina, S., & Septiana, T. (2023). Addition of vitamin e and peperomia pellucida leaves extract on survival and development of fish gonad. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang  21 Oktober 2023. (pp. 490-497).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Belontia hasselti, a valuable economic fish, has faced limited domestication prospects. To address this, an experiment was conducted to assess the impact of supplementing their diet with vitamin E and Peperomia pellucida leaf extract on gonad development. Vitamin E, an essential micronutrient, influences fish reproductive performance, while Peperomia pellucida contains antibacterial and antioxidant compounds that inhibit bacterial growth. This experiment aimed to assess how adding Peperomia pellucida leaf extract and vitamin E to commercial fish feed would affect the gonad development of Belontia hasselti, with the goal of domestication. The study involved two treatments: P1 (standard feed without enrichment) and P2 (enriched with vitamin E and Peperomia pellucida extract). Results revealed significant improvements in gonad maturation, with males reaching TKG III and females TKG IV. Male GSI stood at 0.57%, females at 2.02%, and fecundity at 3,593 eggs. Fish showed absolute weight and length growth of 6.15 grams and 1.7 centimeters, with a survival rate of 83.3%. In conclusion, supplementing commercial fish feed with vitamin E and Peperomia pellucida extract positively impacted Belontia hasselti gonad development, improving maturation levels and reproductive outcomes. To ensure consistent results, it is advisable to tailor the use of these additives in commercial feed to meet the specific needs of the fish.

Abstract

The aspect of Occupational Health and Safety (OHS) is a crucial factor that must be implemented across all industrial sectors, especially in production processes involving heavy machinery and high-risk physical activities. This study was conducted at PT. Putra Agri Pas with the aim of identifying potential hazards and assessing the level of occupational accident risks using the Hazard and Operability Study (HAZOP) approach. This method is applied to detect process deviations and to formulate appropriate preventive strategies. Data were collected through field observations and employee interviews, then analyzed using HAZOP worksheets and the Root Cause Analysis (RCA) method. The research findings indicate that most hazards fall into medium to high risk categories, primarily due to a lack of discipline in using personal protective equipment (PPE), insufficient safety training, and weak operational supervision. The study recommends enhancing control measures, conducting regular training sessions, and organizing the work environment to ensure a safer workplace.
