Abstract

The availability of coconut raw materials in North Sulawesi has made the coconut flour industry increasingly developed. Waste water produced from the coconut flour manufacturing process is not utilized. Pakcoy (Brassica chinensis L.) is a vegetable that is widely cultivated because demand continues to increase due to public awareness of its nutritional value. The aim of the research is to analyze the effect of coconut flour factory waste as organic fertilizer, analyze the effect of water stress on pak choy plants, and analyze the effect of organic fertilizer from coconut flour factory waste on pak choy plants that experience water stress. The sample used was coconut flour factory waste in the form of coconut water from the PT coconut flour factory. Royal Coconut Airmadidi (Poleko). 25 liters of coconut water was fermented with 25 ml of EM4 for 10 days. This research used a Completely Randomized Design (CRD) consisting of 2 factors, 9 treatments and 5 replications. The research results showed that giving coconut water as an organic fertilizer had no significant effect on plant height, number of leaves and fresh weight of the plant. Water stress treatment of pak choy had a significant effect on the number of leaves and fresh weight of the plant, but had no significant effect on plant height.

Abstract

Mangrove Biodiversity of Bunaken National Park For Project-Based Learning To Improve Competitive Student Skills During The COVID 19 Pandemic. College graduates in the era of the industrial revolution 4.0 are required to have strong competitive abilities. Competitive skills can be measured from the science process skills possessed. Objectives: This study aims to obtain a competitive profile of students' skills through a project-based learning method on mangrove biodiversity in Bunaken National Park, North Sulawesi. Methods: The research subjects were students who took Sulawesi biodiversity courses in 2020/2021. Fourteen science process skills were measured using a rubric Findings: The results showed that students' mastery of science process skills was high in the Sulawesi biodiversity course. Conclusion: . The application of project-based learning to the problem of mangrove biodiversity in Bunaken National Park can induce students to develop problem-solving skills, collaboration, creativity, and literacy skills. Keywords: biodiversity mangrove, competitive skills, project-based learning.DOI: http://dx.doi.org/10.23960/jpp.v12.i2.202219

Abstract

Red fruit (Pandanus conoideus Lam) is a native Papuan plant which has been used by indigenous Papuan people as a medicinal plant. Papuan people believe that red fruit has a broad spectrum of pharmacological activity. This research aims to obtain antioxidant activity, namely reducing DPPH free radicals from Papuan red fruit ethanol extract. Samples of red fruit obtained from Nabire Papua. After determination, the red fruit is extracted using the maceration method. The ethanol extract of red fruit was then used for the DPPH antioxidant test method. The results showed that the ethanol extract of red fruit contains phenolic compounds: flavonoids, tannins; and steroids in high intensity. Ethanol extract of red fruit has very strong antioxidant activity (46.99 ppm; R2=0.99). Ethanol extract of Papuan red fruit has potential as a source of bioactive natural antioxidants.

Abstract

Forensic entomology is the science of insects which is used to analyze cases related to forensics, namely death. This is based on the close relationship between humans and insects who live side by side. Insects can be a factor in determining the Postmortem Interval (PMI) so that it is useful in the forensic investigation process. Medicolegal insects are insects that are used as evidence in death cases. This research aims to obtain the diversity of insect species, the morphological characteristics of insects, the characteristics of insects in experimental pigs that died from hanging, poisoning and stabbing and based on the stage of decomposition. The results of this research examine temperature, soil pH, air humidity and the decomposition process of local pigs. The results of research on the decomposition stage in 3 deaths (hanging, stabbing, and poisoning) showed differences in the time of death, where the hanging carcass decomposed more quickly than the stabbed and poisoned carcass. In the decomposition stage, the first insect encountered is the order (Diptera) where these insects damage internal organs such as the brain and liver and also damage body cells. The temperature results of local pig carcasses placed outdoors ranged from 32.2-34.50C, while indoor carcass temperatures ranged from 26.77-33.43 0C. The degree of acidity (pH) of carcasses placed outdoors ranges from 5.13-8.53 while indoor carcasses ranges from 6.0-7.77. The environmental temperature of animal bodies placed outdoors ranges from 26.35-39,740C, while humidity ranges from 57.79-86.10%. The temperature of animal bodies in the room ranges from 27.54-31,520C, while humidity ranges from 71.50-85.37%.

Abstract

This study seeks to evaluate the impact of the guided inquiry learning paradigm on the academic performance of seventh-grade students in biology at SMP Negeri 6 Tondano. This research used a quasi-experimental approach utilising a non-equivalent control group design. The study sample comprised class VII A with 25 students and class VII B with 25 students. This study's variables include the independent variable (X), which consists of users of the guided inquiry learning model, and the dependent variable (Y), which pertains to the learning outcomes of seventh-grade students at SMP Negeri 6 Tondano. Data gathering methods encompass interviews, documentation such as activity reports and pertinent data, and written assessments, including multiple-choice examinations. The hypothesis test employed to assess the difference in student learning outcomes between the experimental and control groups utilises the t-test. The mean post-test learning results for Class VII B students (experimental group) utilising guided inquiry is 82.6. In contrast, the mean outcomes for Class VII A students (control group) employing direct instruction is 77. The hypothesis test findings indicate a t-test value of 2.826, which exceeds the t-table value of 2.010 at a significance level of 0.05. According to the criteria for hypothesis testing, H0 is rejected, and H1 is approved. Consequently, it can be inferred that the guided inquiry learning model positively impacts the learning results of Class VII students in biology at SMP Negeri 6 Tondano.

Abstract

The issue faced in current learning is that it is still teacher-centered, which leads to low student interest and motivation in learning. Additionally, students' attention during lessons is lacking, and they tend to get bored, resulting in poor learning outcomes. This study aims to examine the application of the Guided Inquiry learning model assisted by the Google Lens application to improve the science learning outcomes of seventh-grade students at SMP PGRI POOPO. The subjects of this study were 39 seventh-grade students in the second semester of the 2023/2024 academic year. This research utilized a classroom action research method in two cycles, each consisting of planning, implementation, observation, and reflection stages. The results of the study showed a significant improvement in student learning achievement. The classical completeness percentage in Cycle I was 52.63%, while in Cycle II, it increased to 84.21%. Based on these findings, it can be concluded that implementing the Guided Inquiry learning model supported by the Google Lens application can improve science learning outcomes for seventh-grade students at SMP PGRI POOPO. This model is expected to make students more active, interested, and motivated in learning, leading to better learning outcomes.
