Abstract

The design and analysis of piping systems are critical in the power and process industries. The steam pipe is one of the main requirements for the plant to be installed. High-pressure and high-temperature steam pipes in the piping system are critical lines that need to be subjected to stress analysis. This study aims to evaluate the stress and the effect of using pipe supports on the stress in the piping system. Stress analysis is needed to ensure that the piping system that is designed is safe and does not exceed the allowable stress under operating conditions. Data analysis used ASTM A335-P11 as a pipe material with a design pressure of 65 bars and a design temperature of 480 °C. Stress analysis was carried out using CAESAR II software, which refers to ASME B31.3 process piping standards and codes. The findings revealed that the type of support chosen, such as the gap and distance of pipe support, has a significant impact on the stress value in the piping system. The results of the analysis are carried out several times to get the stress value so that it does not exceed the allowable stress. The greatest stress value occurs at the expansion load condition in the steam pipe system design. The chosen piping system design has a ratio of 93.6%, which is located at node 220 with a stress value of 35889.1 psi and an allowable stress of 38327.2 psi. Because the stress value that occurs is below the allowable stress, the steam pipe system is safe to be installed and operated.

Abstract

Bakso nyatanya tidak banyak mengandung serat pangan walaupun suda bersumber dari daging hewani. Namun, semestinya tubuh sangat membutuhkan serat pangan tersebut untuk Kesehatan. Senyawa anorganik, yang mungkin memiliki konsekuensi negatif jika digunakan dalam jumlah berlebihan dan hal ini biasanya digunakan sebagai bahan pengenyal pada bakso. Menambahkan serat nutrisi pada produk bakso dan membantu memperbaiki tekstur bakso agar lebih kenyal adalah solusi yang mungkin untuk masalah ini. Penggunaan Rumput laut dapat menjadi salah satu alternatif yang dapat digunakan. Karena kegunaan rumput laut sebagai emulsifier selama proses pembuatan bakso, dengan fungsi tersebut penambahan bubur rumput laut dapat meningkatkan kualitas produk. Permasalahan yang ditemukan adalah produk bakso yang dipasarkan di sekitar kampus hanya mengandung karbohidrat yang tinggi dan tanpa serat pangan. Solusi yang ditawarkan yakni dengan adanya produk bakso ikan rumput laut menjadi makanan siap makan yang memiliki gizi seimbang dan kaya serat pangan yang dibutuhkan oleh tubuh.

Abstract

Desa Sungai Dua Laut yang terletak di Kabupaten Tanah Bumbu, Kalimantan Selatan, merupakan kawasan pesisir dengan sumber daya laut yang melimpah, khususnya kepiting rajungan (Portunus pelagicus). Namun, sebagian besar hasil tangkapan masih dijual dalam kondisi segar kepada pengepul tanpa melalui proses pengolahan, sehingga nilai ekonomi yang diterima nelayan relatif rendah. Pengabdian ini bertujuan untuk memberdayakan masyarakat pesisir melalui inovasi pengolahan rajungan menjadi produk bernilai tambah seperti dimsum. Metode yang diterapkan meliputi observasi lapangan, pelatihan pengolahan, pembuatan produk, uji coba pasar, serta pendampingan usaha. Hasil kegiatan menunjukkan bahwa produk olahan rajungan mampu meningkatkan nilai ekonomi, memperpanjang umur simpan, serta membuka peluang diversifikasi pasar pada industri makanan beku. Selain itu, program ini juga meningkatkan keterampilan masyarakat, memperkuat kewirausahaan lokal, dan mendorong pembangunan ekonomi pesisir yang berkelanjutan. Inovasi pangan berbasis sumber daya lokal terbukti dapat menjadi strategi efektif dalam meningkatkan kesejahteraan masyarakat nelayan sekaligus mendukung pengelolaan perikanan berkelanjutan

Abstract

Mathematical representation is a crucial skill that enables students to express, interpret, and connect mathematical concepts through visual, symbolic, and verbal forms. This study explores the differences in mathematical representation skills between students with reflective and impulsive cognitive styles in solving two-variable linear inequality system problems. Using a qualitative descriptive approach, four high school students were selected based on their cognitive styles through the Matching Familiar Figure Test (MFFT). Data were collected through problem-solving tasks and semi-structured interviews. The findings indicate that reflective students demonstrate strong mathematical representation abilities, particularly in organizing and translating information across visual, symbolic, and verbal representations. They exhibit a structured and analytical approach to problem-solving, ensuring accuracy and coherence in their representations. In contrast, impulsive students struggle with problem organization, symbolic representation, and verbal explanation, often producing incomplete and less structured representations due to their tendency to prioritize speed over accuracy. These results highlight the influence of cognitive style on mathematical representation and suggest the need for tailored instructional strategies. Future research should expand the study to a broader mathematical scope and implement targeted interventions to enhance students' representation skills according to their cognitive characteristics.

Abstract

This study examined the effect of Project-based Learning (PjBL) assisted by Microsoft Mathematics on students’ mathematical representation ability. A quasi-experimental design with a posttest-only control group was employed in two tenth-grade classes at a senior high school in Kolaka Regency. The experimental group received PjBL with Microsoft Mathematics, while the control group was taught conventionally. Data were collected through a representation test, a questionnaire, and an observation sheet, and analyzed using both descriptive and inferential statistics. Results showed that the experimental group achieved a significantly higher mean score (81.17) than the control group (60.19), with a mean difference of 20.99 points (p < 0.05). The questionnaire findings revealed very positive student perceptions, indicating that Microsoft Mathematics was easy to use, helpful in understanding concepts, and improved problem-solving skills, while also fostering interest and independence. Observation confirmed that PjBL was implemented effectively: teachers provided clear guidance, students designed projects, collaborated, and presented outcomes through various representations using Microsoft Mathematics. These findings demonstrate that combining PjBL with technology strengthens students’ mathematical representation ability and enriches learning. The study implies that technology-supported project learning can serve as an effective model for promoting meaningful, engaging, and skill-oriented mathematics education in secondary schools.Penelitian ini mengkaji pengaruh Project-based Learning (PjBL) berbantuan Microsoft Mathematics terhadap kemampuan representasi matematis siswa. Desain penelitian yang digunakan adalah kuasi-eksperimen dengan kelompok kontrol posttest-only pada dua kelas X di salah satu SMA di Kabupaten Kolaka. Kelompok eksperimen mendapatkan pembelajaran PjBL dengan Microsoft Mathematics, sedangkan kelompok kontrol diajar secara konvensional. Data dikumpulkan melalui tes representasi, angket, dan lembar observasi, kemudian dianalisis dengan statistik deskriptif dan inferensial. Hasil penelitian menunjukkan bahwa kelompok eksperimen memperoleh skor rata-rata yang secara signifikan lebih tinggi (81,17) dibandingkan kelompok kontrol (60,19), dengan selisih rata-rata 20,99 poin (p < 0,05). Temuan angket menunjukkan persepsi siswa yang sangat positif, bahwa Microsoft Mathematics mudah digunakan, membantu dalam memahami konsep, meningkatkan keterampilan pemecahan masalah, sekaligus menumbuhkan minat dan kemandirian. Hasil observasi menegaskan bahwa PjBL terlaksana secara efektif: guru memberikan arahan yang jelas, siswa merancang proyek, berkolaborasi, serta mempresentasikan hasil melalui berbagai bentuk representasi dengan Microsoft Mathematics. Temuan ini menunjukkan bahwa menggabungkan PjBL dengan teknologi dapat memperkuat kemampuan representasi matematis siswa dan memperkaya pembelajaran. Penelitian ini menyiratkan bahwa pembelajaran berbasis proyek yang didukung teknologi dapat menjadi model efektif untuk mendorong pendidikan matematika yang bermakna, menarik, dan berorientasi pada keterampilan di sekolah menengah.
