REVIEW: EVALUASI PEMANFAATAN KULIT PISANG PADA PAKAN UNGGAS TERHADAP PERFORMA: Review: Evaluation of the Use of Banana Peel in Poultry Feed on Performance
No full textKulit pisang merupakan limbah melimpah yang belum dimanfaatkan secara optimal, meskipun masih mengandung nutrisi yang berpotensi digunakan sebagai bahan pakan unggas. Namun, kulit pisang tidak dapat diberikan secara langsung karena memiliki faktor penghambat kecernaan yang tinggi dan kadar protein yang rendah. Oleh sebab itu, diperlukan teknologi pengolahan, baik fisik, kimia, maupun biologis, untuk meningkatkan kualitasnya sebagai pakan. Penelitian ini bertujuan menilai potensi kulit pisang sebagai bahan pakan unggas dan memberikan referensi pemanfaatannya. Hasil review menunjukkan bahwa kulit pisang dapat digunakan sebagai bahan pakan, baik dalam bentuk tepung maupun tepung fermentasi, tetapi penggunaannya menjadi tidak optimal pada level tinggi. Peningkatan level penambahan tepung kulit pisang maupun tepung kulit pisang fermentasi cenderung menurunkan konsumsi ransum dan pertambahan bobot badan unggas. Konversi ransum terbaik pada ayam broiler dan ayam kampung ditemukan pada penambahan 5% tepung kulit pisang fermentasi, masing-masing sebesar 1,72 ± 0,15 dan 3,65. Pada ayam petelur, konversi ransum optimal dicapai pada level 15% tepung kulit pisang (1,98 ± 0,2). Bobot badan ayam broiler meningkat hingga 1729,84 g pada level 7,5% tepung kulit pisang fermentasi, sedangkan bobot badan itik mencapai 1076,09 g dengan penambahan 7% tepung kulit pisang. Pada ayam petelur, level 8% dapat menghasilkan produksi telur hingga 94,01 ± 1,42%. Secara keseluruhan, kulit pisang dapat digunakan dalam pakan unggas hingga level maksimal 15%. Meski demikian, diperlukan penelitian lanjutan untuk menentukan metode pengolahan terbaik, level penggunaan yang aman dan efisien, serta pengaruh jangka panjang terhadap performa unggas.

STRATEGI PERCEPATAN PERTUMBUHAN EKONOMI KOTA BANDAR LAMPUNG
No full textThis article examines strategies for accelerating economic growth in Bandar Lampung City using a descriptive qualitative approach based on the analysis of regional and national policy documents. The background of this study lies in the city’s 2023 economic growth performance, which reached only 4.99%, falling short of the target set by the Regional Medium-Term Development Plan (RPJMD). The study identifies several structural challenges, including fragmented programs among government agencies, weak inter-sectoral coordination, limited integration between planning and implementation, and minimal involvement of non-government stakeholders. To frame these challenges, three theoretical perspectives are applied: Romer’s endogenous growth theory emphasizes the role of innovation, knowledge, and investment in human capital; Porter’s competitive advantage theory highlights the importance of local industrial clusters in enhancing regional competitiveness; and collaborative governance theory by Ansell and Gash stresses the need for multi-actor engagement in public policy processes. Findings indicate that the city’s sectoral potential remains underutilized, and coordination mechanisms are still largely symbolic. The article recommends integrative strategies that include strengthening institutional synergy, revitalizing key local economic sectors, and developing participatory, data-driven collaborative platforms. These strategies are aligned with the broader national development framework as outlined in the 2020–2024 RPJMN and the Sustainable Development Goals (SDGs), and are expected to contribute to more inclusive, adaptive, and sustainable economic growth at the city level.
