Abstract

The palm flour manufacturing industry produces a lot of liquid waste and solid waste. The absence of a waste processing system means the waste is dumped around the production house. The large amount of solid waste that is dumped every day causes a buildup of waste on riverbanks. The flow of river water is disturbed, pollutes the river ecosystem, and the smell is unpleasant. The research aims to identify the content of N, P, and K elements in palm flour solid waste. The data obtained will be used as a basic reference for using palm flour solid waste as an alternative compost material considering that most of the Pucang Miliran village area is an agricultural area. The research was carried out by taking a sample of 1 kg of sugar palm flour solid waste and testing it for the content of N, P, and K. Data from laboratory tests were analyzed descriptively supported by a literature study. The research results showed that palm flour solid waste contained Nitrogen (N) of 194.227 mg/Kg, Phosphorus (P) of 410.270 mg/Kg, and Potassium (K) of 832.382 mg/Kg. The presence of the three nutrients N, P, and K in large enough quantities can be considered that palm flour solid waste can be a good alternative material for making organic fertilizer/compost. Further research is needed to determine the comparison and combination of various compost material compositions to produce the best palm solid waste compost.

Abstract

Long photoperiods can delay flower initiation and slow down the formation of flower primordia, so they can delay flowering. This study aims todetermine the photoperiodism response of four o'clock flowers (Mirabilis jalapa L.) to the short length of irradiation. The research was carried out for 3months (April-June 2024) and specifically data collection was carried out on 8 June 2024 in Bulurejo village, RT.03 RW. 04, Karangmojo, Weru District,Sukoharjo Regency, Central Java. From 05.53 WIB to 17.30 WIB. Samples of 15 plants growing in Bulurejo village, observed when the flowers bloom. Datawere analysed descriptively qualitative and combined with literature studies. The results of research on 15 plants of four o'clock flower (Mirabilis jalapa L.),the same species and location of four o'clock flower blooming turned out to be different times even though the difference was only slight. The average time ittakes to bloom is 10 hours 42 minutes. Further research needs to be done with a variety of different flowers, not only red flowers, but plus white, red andmixed colours with varied village locations, especially at differentaltitudes.Four o'clock flower (Mirabilis jalapa L) is a member of the family Nyctaginaceae, order Centrospermae, and is easy to grow in the yard withoutmuch care.

Abstract

The Blooms Garden Bali is a tourist attraction featuring various ornamental flowers that can serve as a learning resource for high school biology students. This research aims to identify the ornamental flower species in The Blooms Garden Bali and assess their potential as an educational resource for biodiversity studies. The study employed an exploratory method, involving direct observation and identification of plant species using reference materials and digital tools. Data collection was conducted over five months, from July to November 2024. The results identified 22 ornamental flower species belonging to 14 families and two classes. The findings indicate that these plants can be utilized in biology learning, particularly in biodiversity topics, to enhance students' understanding through real-world applications. The research contributes to the development of interactive learning materials, such as educational presentations and e-modules, aligning with modern digital learning approaches. This study highlights the importance of integrating local biodiversity into biology education, fostering students’ environmental awareness and scientific literacy.
