This study aims to assess the effects of incorporating the Problem-Based Learning (PBL) approach on the acquisition of biology knowledge among PPG students at Manado State University. The research subject comprised 31 students, comprising 14 males and 17 females. This is an instance of educational research referred to as classroom action research, which especially adheres to the approach defined by Kemmis and Taggart. The research was carried out in two distinct phases: the initial phase encompassed planning, execution, action, and observation, while the subsequent phase centered on reflection. Data for the research was gathered by conducting assessments that included both multiple-choice and essay questions. Professionals evaluate Psychomotor learning outcomes through direct observation utilizing a psychomotor assessment form. The cognitive outcomes of cycle I were 51.61% and the cognitive outcomes of cycle II were 80.64%. The psychomotor learning outcomes related to tool and material preparation showed a 19.35% rise, whereas the outcomes for tool and material assembly demonstrated a 25.80% increase. The experimental component experienced a 22.58% increase, the observational component saw a 29.03% increase, and the delivery part of the trial witnessed a significant 41.93% increase. Research indicates that implementing Problem-Based Learning (PBL) can enhance students' academic achievement.

Indonesia ranks 7th out of ten countries with diabetes mellitus, which continues to increase yearly. Honeycomb is rich in secondary metabolites formed from plant resins (propolis) which contain alkaloids, flavonoids, saponins, tannins, steroids and triterpenes. The research aimed to analyze the comparison of flavonoid content and antidiabetic activity with the enzyme Î±-glucosidase In Vitro nest extract of A. mellifera and A. dorsata Binghami. The samples used were nests of A. mellifera from northern Toraja, southern Sulawesi and A. dorsata Binghami from Southeast Minahasa, North Sulawesi. Using 96% ethanol, HPLC method of flavonoid testing and in vitro antidiabetic activity testing using Î±-glucosidase enzymes. The flavonoid content results were based on the number of peaks produced and the retention time of A. mellifera produced 26 compounds, and A. dorsata Bingham produced 21 compounds. The results of in vitro antidiabetic tests with Î±-glucoside enzyme inhibitors obtained IC50 values from the nest extract of A. mellifera of 3.605 mg/L and the nest extract of A. dorsata Binghami of 4.992 mg/L. The extract from A. mellifera had better antidiabetic potential than that of A. dorsata Binghami, although the difference is insignificant.

Skipjack Tuna (Katsuwonus pelamis L.) is a pelagic fish that dominates the waters of the Indian and Pacific Oceans. This fish has unique physical characteristics, including an aerodynamic body, a metallic blue or teal back, and transverse stripes that distinguish it from other species. In Indonesia, skipjack tuna is abundant in the waters of Manado and Maluku. This study aims to determine the types of bacteria present in processed skipjack tuna floss (abon cakalang) based on morphological and physiological characteristics through biochemical tests. This study employs a qualitative descriptive approach conducted in a laboratory setting. Data were gathered through direct observation of samples undergoing various tests and subsequently presented in a descriptive manner. Based on the identification data, 30 bacterial isolates were found in the processed skipjack tuna floss. The isolates were identified macroscopically and microscopically. The findings of the study reveal that the bacteria found in processed skipjack tuna floss, based on biochemical tests and profile matching, are suspected to belong to the Staphylococcus and Vibrio genera.

The aim of this research is: to determine and analyze the effect of giving rice husk charcoal on the growth and production of white cayenne pepper plants (Capsicum frutescens L). The method used in this research is the experimental method with a completely randomized design (RAL) approach. This shows that rice husk charcoal and planting media have different average values for plant height, number of leaves, number of branches, number of fruit and weight of white cayenne pepper. At the 12th week of observation, the M2ASP2 treatment had the highest value compared to other treatments, namely124.65 ± 31.73cm. Meanwhile treatment M1 ASP 0has the lowest value, namely79.23 ± 21.9cm.

Paddy Rice (Oryza sativa) is the main food commodity in Indonesia, because most of the Indonesian population's staple food is Paddy Rice. Demand for Paddy Rice continues to increase from time to time along with population growth. The aim of this research is to determine the types and control of weeds in lowland Paddy Rice plants (Oryza sativa). This research is a qualitative descriptive study using a survey method directly observing weeds in the Paddy Rice planting area in Koya village, South Tondano subdistrict. The results of research on the density, dominance, and frequency of weed types in lowland Paddy Rice plants in Koya Village, South Tondano District show that there are 4 types of weeds in lowland Paddy Rice plants in Koya Village, namely Panicum repens, Fimbristylis litotoralis, Cyperus rotundus, and Pistia stratiotes. P.repens is a grass weed, F.litoralis and C.rotundus are a weed, and P.stratiotes is a broadleaf weed. The type that has the highest relative density (KR) is P. repens, namely 3.33%, followed by F. litoratlis, namely 26.67%, and the lowest is C. rotundus and P. stratiotes, namely 20.0%. Relative Dominance Value The highest (DR) was found in the weed type P. stratiotes, namely 51.56%, then followed by C. rotundus, namely 19.27%, F. litoralis, namely 15.10%, and the lowest, P. repens, namely 14.06%. The highest relative frequency (FR) was in P. repens and C. rotundus, namely 33.33%, followed by F. litoralis, namely 22.22% and the lowest was P. stratiotes, namely 11.11%. Based on the research results, it can be concluded that there are 4 types of weeds in lowland Paddy Rice plants in Koya Village, South Tondano District with the highest weed dominance index value, namely P. stratiotes, namely 27.55787; Weed control can be done chemically, biologically, mechanically and physically.

This study was undertaken in response to the deficient cognitive abilities of students. The problem in this study is whether there is an influence of the project-based learning (PjBL) model, which is assisted by blended learning, on improving students' critical thinking skills in class VIII of SMP Negeri 04 Paleleh Barat. This study aims to determine whether the project-based learning (PjBL) model is assisted by blended learning in students' critical thinking skills in class VIII of SMP Negeri 04 Paleleh Barat. This study was performed in SMP Negeri 04 Paleleh Barat between April to May 2024, employing a quasi-experimental methodology. The sample in this study consisted of class VIII-A as the experimental group and class VIII-B as the control group. Both classes will undergo a learning outcome assessment comprising a pretest and a posttest. The data analysis revealed that the project-based learning (PjBL) paradigm, augmented by blended learning, significantly influenced students' critical thinking skills on the human excretory system in class VIII at SMP Negeri 04 Paleleh Barat. This is derived from the t-test results obtained using IBM SPSS for Windows version 2.2, with a significance value. If the p-value (2-tailed) is less than the significance level (alpha) of 0.05, specifically 0.002 < 0.05, then the null hypothesis (H0) is rejected and the alternative hypothesis (H1) is accepted.
