Abstract

Washing rice in the rice cooking process produces waste in the form of rice washing water. Rice washing water is kitchen waste which contains nutrients and growth hormones for plants. is an experimental study that aims to explore the content and administration of POC from rice washing wastewater with the addition of molasses and EM4 as organic fertilizer at different concentrations on the growth of tomato plants (Solanum lycopersicum L). Completely Randomized Design (CRD) was used with 4 treatments (P0 = Control (Ordinary water), P1 = 1 liter of rice washing water waste + 100 mL molasses + 100 mL EM4, P2 = 3 liters of rice washing water waste + 100 mL molasses + 100 mL EM4, P3 = 5 liters of rice washing water waste + 100 mL molasses + 100 mL EM4) with 7 replications. The data obtained were analyzed using analysis of variance (ANOVA) with SPSS version 23. The results showed that the POC of rice washing water waste had a significant influence on the height of the tomato plant with 87.57 cm, the number of branches on the tomato plant with 16 branches, the number of fruit with 13 pieces, and the weight of the fruit with the tomato plant with 624.28 g, but had no significant effect on the wet weight and dry weight of the tomato plant. Giving POC concentration to treatment P1 gave the most optimal results compared to other treatments. Keywords: Tomato washing water waste, Liquid Organic Fertilizer

Abstract

Dolphin ecotourism is a tourism activity that is educational and related to tour guides who provide interpretation, so this research is important for the sustainability of better dolphin ecotourism. This research was conducted from November to December 2025 which aims to determine the type of interpretation, means of interpretation and the quality of interpretation provided to tourists. The data collection method is accidental sampling by conducting interviews, direct observation, distributing questionnaires and examining related documents. The guides interviewed were 15 people and 25 tourists. The results obtained in this study indicate that the type of interpretation used by dolphin tour guides in Bali amounted to seven types of interpretation types, namely, guided tour, point duty, roving interpretation, lecture or talk, demonstration, translator and living history. The means of interpretation used amounted to four types of facilities, namely print (100%), self-guiding signs (100%), cell phones or social media (100%) and interpretation boards (100%). The overall quality of tour guide interpretation is assessed based on aspects of knowledge, skills and attitude. The quality of the guide's interpretation received an average score that was classified in the good category with a presentation of 76.6%, from the knowledge of 81.2%, the skill of 99.5% and the attitude of 75%. The superior aspect is in the skill aspect of 99.5%. This value indicates that the quality of interpretation of dolphin tour guides in Bali is said to be good.
