Abstract

Holothuroidea atau yang lebih dikenal dengan sebutan teripang laut atau timun laut merupakan salah satu kelas dari Echinodermata. Penampakan morfologi teripang yang hampir mirip satu dengan yang lain mengakibatkan sering terjadi kekeliruan. Penelitian ini bertujuan untuk mengkaji lebih jauh tentang identifikasi Stichopus hermanii berdasarkan morfologi, anatomi serta bentuk dan komposisi spikula yang terdapat pada teripang Stichopus hermanii. Hasil pengamatan morfologi berdasarkan bentuk, corak dan warna serta tipe spikula menunjukkan bahwa Stichopus hermanii berwarna teripang berukuran besar dengan panjang mencapai 50 cm. Teripang ini berwarna kuning-kecoklatan dan pada papila kecil terdapat bercak keabu-abuan di seluruh permukaan tubuh dan bagian dorsal yang berbuku-buku. Bentuk dan komposisi spikula didominasi oleh bentuk roset dan meja dengan bentuk kaki empat.Kata kunci : teripang, Stichopus hermanii, re-deskripsi, morfologi, anatomi, spikula (ossicle)Holothuroidea well-known as sea cucumbers is one class of Echinoderm. Morphology of sea cucumbers are almost similar to each other resulting in frequent error of identification. This study aims to re-describe of Stichopus hermanii based its on morphology, anatomy and the form and composition of the spicules. Results of morphological description based on shape, pattern and color as well as the type of spicules shows that Stichopus hermanii has yelow brownish color. The shape and composition of the spicules is dominated by a rosette shape and a table with four legs form.Keywords : teripang, Stichopus hermanii, re-description, morphology, anatomy, spicule (ossicle)

Abstract

Musical instruments in Indonesia are very diverse, one of which is the tambourine. The tambourine is a round musical instrument made of wood and cowhide. The tambourine instrument is often played in several events such as commemorations of Islamic holidays, weddings, festivities, and so on. But behind this game of the tambourine, there is a physics concept that causes the tambourine to make a beautiful sound. This study uses a qualitative descriptive analysis method with an emphasis on observing the tambourine while it is being played and interviews with one of the players of the tambourine. From this analysis, several physics concepts contained in the game of the tambourine musical instrument will be produced.

Abstract

Mesin Combine Harvester merupakan teknologi vital dalam pertanian modern, terutama dalam pemrosesan padi. Artikel ini menganalisis konsep mekanika yang mendasari mesin Combine Harvester untuk meningkatkan efisiensi dan kualitas panen. Artikel ini menggunakan metode penelitian dengan menganalisis beberapa literatur terhadap data kuantitatif dari berbagai jurnal hasil penelitian dari tahun 2019 hingga 2024. Pada penelitian ini berfokus pada analisis mengenai konsep mekanika yang terdapat pada mesin Combine Harvester dalam pemerosesan padi dengan memperhatikan kualitas serta peningkatan efisiensi. Dengan mengintegrasikan prinsip-prinsip mekanika, seperti mekanika fluida, mekanika material, dan mekanika kinematika, penelitian ini mengeksplorasi bagaimana desain mesin dapat dioptimalkan untuk mencapai hasil panen yang lebih baik dalam hal waktu, tenaga, dan kualitas butiran padi. Analisis ini membahas juga dampaknya terhadap lingkungan dan ekonomi pertanian. Hasil penelitian ini dapat memberikan wawasan yang berharga bagi perancang mesin, petani, dan pemangku kepentingan lainnya untuk meningkatkan efisiensi dan kualitas panen dalam industri pertanian.

Abstract

The issue of household organic waste management remains an environmental problem that has not been optimally addressed in rural areas. Organic waste that is not properly managed has the potential to cause environmental pollution, while on the other hand it has the potential to be used as compost that is beneficial for agriculture. This community service activity aims to increase the knowledge and skills of the Petungsewu Village Young Farmers Group in managing household organic waste into environmentally friendly compost and to encourage the implementation of sustainable waste management. The implementation method uses a participatory approach through the stages of problem identification, socialization, training, interactive discussions, hands-on composting practices, and activity evaluation. The results showed an increase in participants' understanding of the types of organic waste, the basic concepts of composting, the stages of composting, and practical composting skills. The activity also raised environmental awareness and encouraged behavioral changes in the community in waste management. The program had a positive impact in supporting environmentally friendly and sustainable agriculture. It is recommended that the activity be continued through assistance and replication of the program with the support of the local village government.
