Abstract

Danau Limboto memiliki spesies ikan asli, salah satunya yaitu ikan manggabai (Glossogobius giuris). Ikan manggabai merupakan salah satu jenis ikan yang sangat digemari oleh masyarakat khususnya masyarakat Gorontalo. Ikan manggabai merupakan nama lokal dari Nyereh/Manggabai (Glossogobius giuris), atau biasa disebut belosoh atau beloso. Ikan ini biasa hidup di perairan laut, payau serta perairan tawar. Kondisi lingkungan pada danau Limboto yang semakin menurun akan menjadi ancaman bagi ikan-ikan yang berada di danau Limboto. Oleh karena itu maka perlu dilakukan penelitian mengenai analisis proksimat pada ikan manggabai di kawasan danau Limboto, Provinsi Gorontalo. Metode yang di gunakan adalah observasi yaitu melakukan survey langsung ke lapangan terlebih, analisis data menggunakan metode deskriptif kuantitatif. Kandungan proksimat ikan manggabai (Glossogobius giuris) di danau Limboto Provinsi Gorontalo pada empat stasiun yakni kadar protein tertinggi terdapat pada S4 1928,0, kadar air tertinggi terdapat pada S4 82,8%, kadar abu tertinggi terdapat pada S3 1,15%, kadar lemak tertinggi terdapat pada S4 1,4% dan kadar karbohidrat tertinggi terdapat pada S4 28,3%.

Abstract

This study aims to analyze the effect of implementing the Pancasila Student Profile Strengthening Project (P5) through an edu-tourism-based approach on students’ critical thinking skills in Civic Education (PPKn) at the elementary school level. Edu-tourism-based learning offers contextual experiences that enable students to directly observe national values in real environments while fostering in-depth analysis and reflection. A quantitative approach with a quasi-experimental nonequivalent control group design was employed. The subjects were two fourth-grade classes assigned to experimental and control groups. Statistical tests confirmed the normality and homogeneity of the data. ANOVA analysis indicated a significant effect of the edu-tourism-based P5 on improving students' critical thinking skills. The experimental group showed a significantly higher post-test average score than the control group. These findings confirm that edu-tourism, as a contextual approach, is effective in Civic Education for developing students' critical thinking skills optimally. ABSTRAKPenelitian ini bertujuan untuk menganalisis pengaruh penerapan Projek Penguatan Profil Pelajar Pancasila (P5) berbasis eduwisata terhadap kemampuan berpikir kritis peserta didik dalam pembelajaran Pendidikan Pancasila dan Kewarganegaraan (PPKn) di sekolah dasar. Pembelajaran berbasis eduwisata memberikan pengalaman kontekstual yang memungkinkan peserta didik mengamati langsung nilai-nilai kebangsaan di lingkungan nyata, serta mendorong proses analisis dan refleksi yang mendalam. Pendekatan kuantitatif dengan desain quasi eksperimen tipe nonequivalent control group digunakan dalam penelitian ini. Subjek terdiri atas dua kelas IV, yaitu kelas eksperimen dan kelas kontrol. Hasil uji statistik menunjukkan bahwa data berdistribusi normal dan homogen. Analisis ANOVA menunjukkan pengaruh signifikan penerapan P5 berbasis eduwisata terhadap peningkatan kemampuan berpikir kritis siswa. Rata-rata nilai posttest kelompok eksperimen meningkat secara signifikan dibandingkan kelompok kontrol. Temuan ini memperkuat bahwa eduwisata sebagai pendekatan kontekstual efektif digunakan dalam pembelajaran PPKn untuk mengembangkan kemampuan berpikir kritis peserta didik secara optimal.

Abstract

Kopi Gayo merupakan komoditas unggulan dari Aceh Tengah yang memiliki reputasi internasional, namun kualitasnya masih dipengaruhi oleh praktik pascapanen yang belum sesuai standar. Kegiatan pengabdian kepada masyarakat ini bertujuan meningkatkan pemahaman dan keterampilan petani kopi terkait pengelolaan mutu biji kopi sesuai SNI 01-2907-2008. Metode pelaksanaan dilakukan melalui penyuluhan partisipatif, diskusi interaktif, serta pendampingan praktik pemetikan selektif, sortasi, dan pengeringan terkontrol. Penyuluhan menekankan pemetikan buah kopi matang (red cherry), prinsip pengeringan hingga kadar air 11–12%, serta sortasi biji sesuai indikator mutu. Hasil kuesioner menunjukkan tingkat kesulitan yang bervariasi, di mana pemenuhan kriteria bebas serangga hidup dan kadar kotoran mudah dilakukan, sedangkan pengendalian bau busuk dan kadar air menjadi tantangan utama. Pendampingan praktik sortasi dan pengeringan berhasil meningkatkan keterampilan petani, dengan capaian mutu biji kopi bebas serangga, tidak berbau busuk, kadar air 11–12%, dan tanpa kotoran. Program ini membuktikan bahwa penyuluhan dan pendampingan pascapanen mampu meningkatkan kesadaran serta penerapan standar mutu kopi oleh petani. Dengan demikian, kegiatan ini berkontribusi dalam menjaga reputasi Kopi Arabika Gayo sekaligus meningkatkan daya saingnya di pasar domestik maupun global.

Abstract

Efforts to manage waste are being carried out at various levels, ranging from households to large-scale industries that generate waste on a daily basis. The imbalance between waste generation and proper management has turned waste into a serious environmental concern. Among the different types of waste, plastic is one of the most difficult to naturally decompose (non-biodegradable) and represents the largest portion compared to other waste materials. Statistical data show that in several cities across Indonesia, the amount of non-biodegradable waste disposed of at final disposal sites reaches 6,598.23 tons per day. This study was conducted with both general and specific objectives. The general aim was to utilize plastic waste as a composite material, while the specific objective was to analyze the tensile strength properties of composites produced from plastic waste reinforced with durian fibers. By exploring the potential of plastic waste in construction materials, this research seeks to provide a sustainable solution to the plastic waste problem while contributing to environmental preservation. Four different specimens were prepared for testing: Specimen A (80% plastic waste and 20% durian fiber), Specimen B (60% plastic waste and 40% durian fiber), Specimen C (40% plastic waste and 60% durian fiber), and Specimen D (20% plastic waste and 80% durian fiber). The results revealed that Specimen B exhibited the highest average tensile strength of 20.9 MPa, indicating significant potential for enhancing material performance. In contrast, Specimen D showed the lowest average tensile strength of only 1.2 MPa, highlighting the need for further composition optimization to improve mechanical properties. Overall, this study provides valuable insights into the development of recycled composite materials for use in construction and broader industrial applications.

Abstract

This study aims to analyze the stress and strain distribution on the front planetary sun gear of a helical differential using the Finite Element Method (FEM). The analysis was carried out under two conditions: without a crack and with an initial crack of 1 mm placed at the tensile side tooth root, in order to evaluate the effect of defect presence on the mechanical behavior of the gear under an operational torque load of 175 Nm. Three-dimensional modeling and meshing were performed using ANSYS software, with SCM420 steel as the material, which has an allowable stress of 1,300 MPa. The simulation results show that the maximum stress in the uncracked model reached 8,859.6 MPa, while in the cracked model it increased to 15,258 MPa. Meanwhile, the maximum equivalent elastic strain increased from 4.437 × 10⁻² mm/mm to 1.154 × 10⁻¹ mm/mm. This significant increase indicates that the presence of an initial crack intensifies stress concentration and amplifies local deformation, potentially accelerating crack initiation and propagation due to the increased strain energy accumulated near the crack tip. Based on these findings, optimization of the fillet radius and the application of surface treatments such as shot peening or advanced carburizing are recommended to reduce peak stresses and extend gear fatigue life. The results of this study demonstrate that the FEM approach is effective in predicting structural behavior and serves as a basis for the development of reliability-based design and condition monitoring systems in modern automotive transmissions.
