Abstract

Patchouli plants (Pogostemon cablin) in Batu Putih Village often die from erratic seasons. Excess soil water content during the rainy season causes plants to rot and die. In other cases, the death of patchouli is also caused by a lack of water content in the soil. This study aims to determine the effect of soil water content on the growth of patchouli (Pogostemon cablin) in Batu Putih Village, Batu Putih District, and North Kolaka Regency. This study used a randomized block design (RBD) method with two treatment factors, namely the material type and the groundwater concentration. Each type of material consisted of patchouli, soil and water, while the groundwater concentration consisted of watering 100% (500 ml), 60% (300 ml) and 40% (200 ml). The results showed that watering with 100% groundwater concentration (500 ml) gave the best growth compared to water at 60% and 40% groundwater concentrations. However, the results of the Anova test showed that watering with 100%, 60%, and 40% groundwater concentrations did not have a significant effect on plant growth, it was suspected that water was not the dominant factor in the patchouli plant growth process.  Keywords: Patchouli, growth, soil moisture content, Pogostemon cablin.

Abstract

     As much as 60% of waste in Indonesia is organic waste, one of which is onion skin waste. Onion skin is often thrown away and not reused. Based on references, shallot skin contains the hormones auxin and gibberellin, which are growth hormones that can be utilised as growth regulators. Popular scientific books on growth regulators from shallot skin extract are still minimal so it is necessary to develop this book. The purpose of this study was to describe the validity and readability of the Popular Science Book digital ZPT of shallot skin extract on the growth of green mustard. The type of research used is Educational Design Research (EDR) development research which includes preliminary research, product prototype design phase (prototyping phase), and product assessment phase by experts (assessment phase) but in this study only up to the product prototype design phase (prototyping phase). This research uses Tessmer's formative evaluation which includes self-evaluation, expert review and one to one evaluation. Validity data was taken from expert validation data as many as three experts using questionnaire instruments. one to one evaluation data to obtain book readability data was obtained from 6 people including 3 students and 3 people from the community. Data on the validity and readability of the book were analysed using Akbar's category. The results showed that the results of the validity test of popular scientific books were 79.85% with a fairly valid category and the readability test data was obtained at 88.88%, showing very good quality.

Abstract

Cognitive learning outcomes are an aspect related to the reasoning or thinking process, namely the ability and activity of the brain to develop rational abilities. Based on observation of schools in Balikpapan, students’ cognitive learning outcomes still have not achieved the minimum completion criteria (KKM). Students have difficulties in learning archaebacteria and eubacteria because the concepts are abstract. The lack of variations in learning media has made this topic more difficult to teach. This research aimed to determine the influence of Archaebacteria and Eubacteria web-based learning media on students’ cognitive learning outcomes in Balikpapan. The type of research was quasi-experimental with a pretest-posttest control group design. The study population was all senior high schools in Balikpapan. The sampling technique used purposive sampling. The samples of this research were three senior high schools in Balikpapan. The subjects of this research were students of SMAN 1 Balikpapan, SMAN 2 Balikpapan, and SMA Patra Dharma Balikpapan. Data analysis technique using ANCOVA (SPSS Statistics 23). According to the research findings, the average cognitive learning score of the cognitive learning score test in the experimental class is higher than the control class, which is 72.98 67.84. The prerequisite test shows that data were normally distributed and class groups derived from a homogenous population. The hypothesis test using ANCOVA at a 0.05 significance level shows that there is an effect of applying web-based learning media on students’ cognitive learning outcomes in learning archaebacteria and eubacteria.

Abstract

AbstractThe analysis of water quality in the post-sand mining swamp of Kranjingan indicates that the aquatic environment is in relatively good condition, with a neutral to slightly alkaline pH, stable temperature, and total dissolved solids (TDS) within acceptable limits. Although slight variations were observed between stations, particularly at Station 4, which recorded the highest TDS value, the overall water conditions still support the sustainability of the aquatic ecosystem and allow for various sustainable utilizations. The study's objective is to analyze the water quality in the post-sand mining swamp of Kranjingan and evaluate the sustainability of the aquatic ecosystem in the area. This research also aims to understand the composition and abundance of phytoplankton to determine the trophic status of the ecosystem. The study results show that the composition and abundance of phytoplankton in the post-mining swamp exhibit oligotrophic characteristics, with a dominance of the Cyanophyta phylum, particularly Microcystis. The highest phytoplankton diversity was found at Station 2, while Station 4 demonstrated relatively stable abundance. These findings provide essential insights into the management and utilization of post-sand mining swamps for both ecological and economic purposes. Keywords: phytoplankton, water quality, post-sand mining swamp, Kranjingan, Jember
