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 determine the effect of the Project Based Learning learning model using Mind Mapping on student learning outcomes in class VIII of SMP Negeri 5 Bolano Lambunu. This research method is a quasi-experiment (Quasi Experiment) with a Non-equivalent (Pretest and Posttest) Control Group Design. The sample of this study was 34 students, consisting of 17 students in the experimental class who used the Project Based Learning learning model using Mind Mapping and 17 students in the control class who used the conventional learning model. Data collection was carried out by conducting observations, interviews, and tests. Data analysis used prerequisite tests, namely, normality tests and homogeneity tests and hypothesis testing using the Independent Sample t-test and N-gain tests. The results of the study showed that (1) there was an effect of using the Project Based Learning learning model using Mapping on student learning outcomes. This is evidenced by a significant increase in student learning outcomes in the experimental class, with an average posttest score reaching 73.23, while the control class was only 64.70. The t-test shows a p value < 0.05, which means that the implementation of the Project Based Learning model using Mapping has a positive effect on student learning outcomes. (2) N-gain analysis shows that the experimental class has an average N-gain score of 0.65 (65%), which is included in the fairly effective category, while the control class is only 0.51 (51%), which indicates a less effective category. Thus, it can be concluded that the Project Based Learning learning model using Mind Mapping is effective and can affect student learning outcomes in the science subject of class VIII-B SMP Negeri 5 Bolano Lambunu.

Abstract

Program pengabdian masyarakat ini dilaksanakan bekerja sama dengan Usaha Mikro, Kecil, dan Menengah (UMKM) Cendana di Kelurahan Lere, Kota Palu, dengan tujuan untuk memperkuat kapasitas mitra dalam mengembangkan produk pangan fungsional dari sumber daya lokal. Biji labu kuning, yang seringkali kurang dimanfaatkan, diolah menjadi snack bar sehat melalui serangkaian kegiatan, termasuk pelatihan, praktik langsung, dan pendampingan teknis. Program ini melibatkan 15 peserta dan dievaluasi menggunakan instrumen pre-test dan post-test untuk menilai peningkatan pengetahuan, serta observasi untuk mengukur penguasaan keterampilan. Hasilnya menunjukkan peningkatan pengetahuan peserta yang signifikan, dengan skor rata-rata meningkat dari 60,67 pada pre-test menjadi 85,40 pada post-test. Selain peningkatan pengetahuan, peserta mampu memproduksi snack bar berbahan dasar biji labu kuning secara mandiri dengan kualitas yang baik, rasa yang bervariasi, dan kemasan yang sesuai. Produk ini menunjukkan nilai gizi yang tinggi, kepraktisan, dan potensi pasar yang menjanjikan sebagai pangan fungsional. Secara keseluruhan, program ini memberikan manfaat nyata bagi UMKM mitra, terutama dalam hal peningkatan keterampilan, diversifikasi produk, dan perluasan peluang usaha.
