Abstract

Kabupaten Purworejo merupakan salah satu penghasil kelapa di Jawa Tengah, berbagai produk olahan berbahan kelapa dihasilkan oleh UMKM, salah satunya adalah pengolahan minyak kelapa. Pengolahan minyak kelapa menghasilkan limbah yaitu ampas kelapa. Saat ini ampas kelapa dimanfaatkan sebagai pakan ternak. Jumlahnya yang banyak, pengambilan yang tidak kontinyu dan penyimpanan pada tempat terbuka menyebabkan permasalahan lingkungan seperti bau yang tidak sedap, pencemaran air serta potensi penyebaran penyakit merupakan efek negatif dari limbah ini. Biokonversi menggunakan Larva Black Soldier Fly (BSF) diharapkan mampu mengurangi limbah organik. Penelitian ini menggunakan limbah ampas kelapa dengan variasi pemberian pakan sebesar 60, 80, 100, 120, 140 mg/larva/hari. Larva yang digunakan adalah sebanyak 200 ekor pada tiap perlakukan dengan 3 ulangan. Masa observasi dan pemeliharaan larva adalah 21 hari dan kemudian diamati Berat Larva, Survival Rates, Substrate Consumption, Biomassa Larva, residu pakan, analisa proksimat serta analisa kelayakan usaha dari produksi pengolahan larva Black Soldier Fly (BSF). Hasil penelitian menunjukkan bahwa Larva Black Soldier Fly (BSF) tumbuh optimum pada feeding rate 60 mg/larva/hari. Dalam masa pemeliharaan 21 hari dengan variasi feeding rate 0mg/larva/hari, 60mg/larva/hari, 80mg/larva/hari, 100mg/larva/hari, 120mg/larva/hari dan 140mg/larva/hari diperoleh substrate consumption sebesar 0 %, 75.63 %, 62.67%, 54.92%, 46.87% dan 35.75%.

Abstract

This study analyzes the strategies for developing entrepreneurial character at the Al-Firdausiy Islamic Boarding School in Semarang. Using a qualitative approach with a phenomenological design, data were obtained through observation, interviews, and documentation, then analyzed using the Miles and Huberman model. The results indicate that the development of students' entrepreneurial character is carried out through three main strategies: (1) cognitive development through the study of classical texts such as Fathul Qorib and Bulughul Marom, as well as training in basic entrepreneurial theory, including profit calculation, risk mitigation, and market price analysis; (2) the development of entrepreneurial attitudes and principles through the Semarang Ngajiyuk Institute program and the character-based Islamic boarding school; (3) the development of behavior through direct practice, such as selling activities on campus. Entrepreneurial character is a key program of the Islamic boarding school, with the vision of "good morals, good at reciting the Quran, and good at trading." This program has resulted in students becoming independent, disciplined, creative, and responsible.
