Abstract

Salah satu kendala dalam budidaya ikan lele (Clarias sp) adalah efisiensi pakan yang rendah. Oleh karena itu, diperlukan suatu terobosan dalam budidaya ikan lele guna meningkatkan efisiensi pemanfaatan pakan yang berujung pada peningkatan produksi dan profit usaha budidaya ikan lele. Penelitian ini bertujuan untuk mengevaluasi pengaruh dari suplementasi ekstrak batang pisang terhadap kinerja pertumbuhan ikan lele di kolam tanah gambut tergenang. Pada penelitian ini terdiri dari empat perlakuan, yaitu kontrol (A), ekstrak batang pisang dengan dosis 2% (B), ekstrak batang pisang 4%(C), dan ekstrak batang pisang 6%(D) di campurkan ke dalam pakan dengan ulangan tiga kali. Ikan dengan bobot awal rata-rata 1,25 g ditebar secara acak pada 12 hapa berukuran 1 x 1 x 1 m³ yang dipasang pada kolam tanah dengan kepadatan 40 ekor/hapa. Ikan diberi pakan uji secara ad satation dengan frekuensi dua kali sehari selama 14 hari. Suplementasi Ekstrak batang pisang (perlakuan B) menunjukan nilai rata-rata hasil yang lebih baik pada parameter kinerja pertumbuhan ikan lele, yaitu jumlah konsumsi pakan lebih hemat, laju pertumbuhan bobot harian, laju pertumbuhan spesifik, efisiensi pakan lebih tinggi dan rasio konversi pakan lebih rendah dibanding perlakuan lainnya. Suplementasi Ekstrak batang pisang menunjukan pengaruh positif pada jumlah konsumsi pakan (165g), laju pertummbuhan bobot harian(8,21g/hari), laju pertumbuhan spesifik (12,31%/hari), efisiensi pakan(69,85), yang ditunjukan dengan nilai rasio konversi pakan (1,43)

Abstract

The performance of the South Sumatra Provincial Government is reflected in the quality of innovation, program development, public services, and administrative processes related to the task and function of improving people's welfare. Performance productivity is measured by reducing poverty, increasing economic growth, and increasing local income. One of the improvements in performance is the work of middle level management in addition to the work of other levels of top management and low management. This study will answer the question of what factors can significantly to improve the performance of the government of South Sumatra Province. This paper will examine the factors of self-efficacy and affective commitment which are seen as determinants of improving the performance of the government of South Sumatra province, because it is one of the advantages of human resources and is a productive added value. However, previous studies on self-efficacy and affective commitment provide evidence that these two factors produce inconsistent research findings or gaps. Therefore empirically recommends that the effect of self-efficacy and affective commitment to improve performance requires further research to be justified. To resolve the gap of self-efficacy and affective commitment to the performance of the government of South Sumatra province, researchers adopted the theory of goal setting with the concept of competitive leadership with good organizational indicators, applying technology, sustainable work programs, and developing wider networks as a result of efficacy self and affective commitment can henceforth be used to improve organizational performance. The sample was used 108 respondents who held administrative positions with SEM LISREL 9.30 data processing. This conceptual model is expected to prove thatcompetitive shared leadership that is influenced by self-affication and affective commitment significantly improves the performance of the government of South Sumatra province.
