Abstract

This Classroom Action Research (CAR) aims to enhance students’ learning motivation through the implementation of the Snowball Throwing learning model. The study was conducted at SMAN 1 Palu with 35 students of class XI MIPA 6 as the research subjects. The CAR was carried out in three phases: pre-action, Cycle I, and Cycle II. Data were collected through observation and a learning motivation questionnaire. The findings revealed that students’ learning motivation in the pre-action phase was categorized as “fair” with a percentage of 54%. After the implementation of the Snowball Throwing model in Cycle I, students’ motivation increased to 72% (“high” category), and in Cycle II it further improved to 87% (“very high” category). These results indicate that the Snowball Throwing model is effective in improving students’ learning motivation, as it actively engages them in discussion and collaborative activities, making the learning process more interactive and enjoyable. The implication of this study is that teachers may employ the Snowball Throwing model as an alternative instructional strategy in Biology learning to foster students’ learning motivation.

Abstract

Apis nigrocincta is an endemic honey bee that is only found in two regions in Indonesia, namely the Sangihe Islands and Sulawesi Islands. Phylogenetic analysis is used to describe the phylogenetic relationship of Sulawesi endemic honey bee A. nigrocincta based on the 16S rRNA gene. Sampling using the cruising method in various regions, then DNA isolation, DNA amplification, sequencing, and continued bioinformatics analysis using GeneStudio, DNASTAR, MESQUITE, and MEGA 11. The results showed that phylogenetic analysis with the Neighbor-Joining (NJ) and Maximum Likelihood (ML) methods produced a phylogenetic tree that illustrates clear evolutionary relationships. A. nigrocincta from Central Sulawesi is more closely related to other A. nigrocincta species in the same clade, while other species are separated. The results of this study show a clear pattern of kinship between A. nigrocincta populations.

The study uses explorative descriptive methods with qualitative and quantitative approaches. The focus of this study is the identification of feed source for endemic honeybees of Sulawesi, Apis nigrocincta through the analysis of polent morphology. Through the approach of polent morphology analysis, successfully identified 12 plant species from 9 families that could potentially be feed sources such as, Cucurbita maxima, Clematis viticella, Clematis montana, Pseuderanthemum tropurpureum, Cersicaria odorata, Solamun torvum, Solamun nigrum, Pine mercussii, Piper betle, Piper nigrum, and Galium aparine identification showed the presence of polyn diversity that supports the nutritional needs of bees, and emphasized the importance of local vegetation conservation to maintain the sustainability of the A. nigrocincta population. The results of the study showed that the polen has characteristics such as the polish unit, size, shape, shape on the P and E side, aperture type, as well as exin ornamentation. The polents collected by bees A. nigrocincta come from various types of plants, namely fruits, ornamental plants, vegetable plants, herb plants, and trees. This diversity reflects the flexibility of bees in choosing food sources based on availability in the surrounding environment. The results of the identification of the polymer samples showed that 12 species of plants that are the main feed source for A. nigrocincta bees are sourced from the polen. Each species has different flower characteristics, both in terms of shape and color. Polen diversity indicates that the environment around Jononunu Village has a rich ecosystem with different types of flowering plants.

Abstract

This study aims to determine the density of macrozoobenthos in Toaya Village River Waters. This study uses a Quantitative Descriptive method with purposive sampling location determination consisting of 3 observation stations and sampling using the line Transect technique with a surber net sampling tool. Data analysis is done by calculating the density of samples that have been obtained in the field using the density formula. The results showed that (1) 5 types of macrozoobenthos were identified in the waters of Toaya Village River with the highest density at Station I (9.17 ind/m²) and the lowest at Station III (6.25 ind/m²). (2) These density differences reflect variations in environmental conditions, such as bottom substrate, water currents, pollution levels, and availability of organic matter. (3) Environmental conditions at station 1 are relatively more favorable for benthic organisms, while stations II and III reflect environmental pressures such as pollution or changes in habitat quality. Thus, macrozoobenthos acts as an effective bioindicator to assess water quality, so these results reflect the health level of the river ecosystem.

Abstract

This study aimed to identify bivalve species with high microplastic content and the types of microplastics present in those bivalves within the mangrove ecosystem of Desa Tanah Mea, Donggala Regency.  A quantitative descriptive method was used. Sampling locations were determined using purposive sampling, divided into two stations: Station I, a mangrove ecosystem adjacent to a residential area, and Station II, a mangrove ecosystem near the coastline. Bivalve samples were collected using the hand collection method, with 10 individuals per species.  Subsequently, bivalve tissues were processed, and microplastic content was analyzed. Data analysis involved counting the number and types of microplastics from the field samples using an abundance formula. Results showed that Polymesoda erosa, found at Station I, contained 22.2 microplastic particles per individual, comprising 104 fragments, 22 films, 92 fibers, and 4 foams.  Anadara granosa, found at Station II, contained significantly fewer microplastics, with 2.5 particles per individual, consisting of 12 fragments, 5 films, and 8 fibers. Polymesoda erosa was the bivalve species with the highest microplastic content, with fragments, films, fibers, and foams identified.  Therefore, bivalves can serve as bioindicators for assessing microplastic pollution levels in the mangrove ecosystem of Desa Tanah Mea, Donggala Regency.

Abstract

This study aims to describe and compare the anatomical structure of mangrove leaves of Avicennia lanata Ridl. and Sonneratia alba J.E. Smith in the coastal area of Central Siney Village, South Tinombo District, Parigi Moutong Regency. This study used a quantitative descriptive approach and was conducted at the Biology Education Laboratory, Faculty of Teacher Training and Education, Tadulako University in November 2024. The research samples were A. lanata and S. alba mangrove leaves collected from the research location, with data obtained through microscopic observation, documentation, and questionnaires. The results showed that there were differences in the anatomical structure of the leaves of the two mangrove species, especially in the type of stomata, the thickness of mesophyll tissue, and the development of salt glands. Avicennia lanata has actinocytic stomata and more developed salt glands, while Sonneratia alba has cyclic stomata and thicker pole tissue. Both have similar basic leaf structures, such as cuticle, epidermis, cortex, and xylem and phloem transport tissues. Thus, there are distinctive anatomical adaptations in each species, reflecting survival strategies in the mangrove ecosystem.

Abstract

This study aims to identify Bacillus sp. in cassava tapai fermentation that has potential as a probiotic ingredient. The type of research used is descriptive exploratory using the Standard Plate Count (SPC) method, Gram staining, and biochemical testing with the Microbant System 12B. Cassava tapai samples were obtained by fermenting them for 5 days. Fermentation of cassava tapai was carried out in the Biology Education Laboratory. The results of the study showed that (1) The Standard Plate Count test yielded the highest value on the 4th day of observation at 231x10-2 CFU/ml, while the lowest value was observed on the 1st day at 162x10-2 CFU/ml. (2) Gram staining of the bacterial isolates revealed Gram-positive rod-shaped morphology. (3) Biochemical testing using the Microbant System 12B showed the ability to ferment several types of carbohydrates such as sorbitol, sucrose, lactose, arabinose, adonitol, and salicin, but it cannot ferment inositol, malonate, rhamnose, raffinose, and arginine. Thus, it can be concluded that the bacteria identified from cassava tapai fermentation can ferment in accordance with the physiological capabilities of Bacillus sp.
