Abstract

Peanut is an important agricultural commodity in Indonesia as a protein and vegetable oil source. Soil conditions in Indonesia are usually ultisol soils that have low pH and nutrients, this is an obstacle in peanut cultivation. This study was conducted to determine the effect of a combination of calcite sources and organic fertilizers on the growth and yield of peanut in ultisol soil. This research was conducted from May to August 2024 at UPTD Balai Benih Pertanian Air Pelempang, Bangka Regency. The research used a split-plot randomized group design. The main plot was without a calcite source (P1), agricultural calcite (P2), and gypsum waste (P3). Subplots were commercial compost (K1), chicken manure (K2), and cow manure (K3). Data analysis was performed using an analysis of variance with a significant level of 95% and a follow-up test with Duncan's Multiple Range Test with a significant level of 95%. The results showed that the treatment of calcite sources from agricultural calcite was better than the treatment of gypsum waste and without calcite sources. The treatment of organic fertilizer from chicken manure was better than cow manure and commercial compost. The combination that gave the best results with the highest value was agricultural calcite and chicken manure fertilizer, which affected all parameters except the percentage of effective root nodules, root dry weight, and flowering age. Gypsum waste has the potential to be a substitute for agricultural calcite when combined with chicken manure fertilizer, as it does not have significant results with agricultural calcite.

Abstract

This research was conducted at PLTU Teluk Balikpapan. The research objective was to analyze the implementation of a safety permit based on the reference standards Guidelines on Permit to Work System-Oil and Gas Producers 2003. This type of research is descriptive-qualitative. The results of the research on the safety permit procedure of PLTU Balikpapan have the conformity of 89% with the Guidelines on Permit to Work System-Oil and Gas Producers 2003. The remaining 15% is in the form of non-conformities at the preparation stage, namely in the isolation stage at PLTU Teluk Balikpapan using Log Out Tag Out (LOTO ) by installing locks and warning signs on equipment in the form of barricades around the work area. Apart from that, in the process stage, the display of permit on the information board or wallpaper for a safety permit is not made. In conclusion, the tagging system and key installation have been implemented, but there is only 1 (one) key provided and held by the operator, so accessing the equipment/system with multiple work permits will experience problems. other than that, the display of permit on the information board is not made.
