The trophic ecology of Sciaenid fishes, one group of the demersal fishes in Pabean Bay, Indramayu is described in our study. A total of 14 types of prey were identified belonging to three groups (Decapod Crustacean, Mollusca, and Bony fishes) to analyze the feeding preferences and diet breadth overlap. The preferred prey items of Johnius belangerii (Belanger's croaker) were Calappidae (Ii = 16.12), followed by Squilla sp. (15.5), and Penaeus sp. (14.6); while Johnius borneensis (Sharpnose hammer croaker) were Penaeus sp. (Ii = 86.5), followed by Calappidae (3.45), and Acetes sp. (1.38); Johnius macropterus (Largefin croaker) were Penaeus sp. (Ii = 35), followed by Callapidae (5); Nibea soldado (Soldier croaker) were Penaeus sp. (Ii = 25.63) followed by Squilla sp. (23.98), and Charybdis sp. (16.42); Otolithes ruber (Tigertooth croaker) was Penaeus sp. (Ii = 25.63). The diet breadth (BA) values indicate that Sharpnose hammer croaker (BA = 0.06) and Tigertooth croaker (BA = 0.07) are high specialist consumers, while Belanger's croaker (BA = 0.36) and Soldier croaker (BA =0.34) are considered as non-specialized feeders. Our study showed that sciaenid fishes have overlapping trophic niches intra and inter-specific due to their common feeding on decapod crustaceans. The high trophic overlap between predators suggests that Sciaenid fishes in Pabean Bay are competing with each other when food resources are limited. Abstrak Ekologi trofik famili Sciaenidae, salah satu kelompok ikan demersal di perairan Teluk Pabean, Indramayu dideskripsikan melalui studi ini. Sebanyak 14 jenis makanan dari tiga kelompok utama (Krustasea Decapoda, Moluska, dan ikan bertulang sejati) berhasil diidentifikasi untuk analisis preferensi dan tumpang tindih relung makanan ikan Sciaenidae. Mangsa yang diminati oleh ikan Johnius belangerii (Belanger's croaker) adalah Calappidae (Ii = 16,12), diikuti oleh Squilla sp. (15,5), dan Penaeus sp. (14,6); sementara ikan Johnius borneensis (Sharpnose hammer croaker) menyukai Penaeus sp. (Ii = 86,5), disusul oleh Calappidae (3,45), dan Acetes sp. (1,38); ikan Johnius macropterus (Largefin croaker) menyenangi Penaeus sp. (Ii = 35), diikuti oleh Callapidae (5); sedangkan ikan Nibea soldado (Soldier croaker) cenderung memilikih Penaeus sp. (Ii = 25,63), Squilla sp. (23,98), dan Charybdis sp. (16,42); sedangkan Otolithes ruber (Tigertooth croaker) lebih banyak mengonsumsi Penaeus sp. (Ii = 25,63). Nilai relung makanan (BA) mengindikasikan bahwa ikan Sharpnose hammer croaker (BA = 0,06) dan Tigertooth croaker (BA = 0,07) adalah termasuk pemangsa yang spesialis, sedangkan Belanger's croaker (BA = 0,36) dan Soldier croaker (BA = 0,34) lebih cenderung sebagai pemangsa yang bukan spesialis. Tumpang tindih relung makanan khususnya jenis krustasea decapoda terjadi baik antarspesies maupun antar individu dari spesies yang sama, termasuk antar kelompok ukuran. Tumpang tindih relung makanan yang tinggi antar ikan predator menunjukkan bahwa kelompok ikan Sciaenidae di Teluk Paben berkompetisi memperebutkan makanan saat terjadi kelangkaan sumberdaya makanan.
ABSTRACT Performance is the output of something that has been done that is used to measure a person's overall success rate for a certain period of time compared to the standard of work, targets to be set and agreed. This study analyzes the Audit structure, role conflict, role ambiguity on the performance of internal auditors in government for which role overload as a moderating variables. The population in this study is the government's internal auditor belonging to the Joint Assessment Team Credit Score Auditor consisting of the Arsip Nasional Republik Indonesia, Badan Pengawas Tenaga Nuklir, Lembaga Sandi Negara, Kementerian Pemberdayaan Perempuan dan Perlindungan Anak and Kementerian Koordinator Bidang Pembangunan Manusia dan Kebudayaan. The Metode of sampling using saturation sampling (census). This study used Structural Equation Model (SEM) 4.0 WarpPLS programs to test the hypothesis. The results show that there are a positif effect among Audit structuretoward performance audit of government's internal auditor, there are no effect among role conflict and role ambiguity toward performance audit of government's internal auditor, and role overload is not moderating variable for the relationship Audit structure with performance audit of government's internal auditor. ABSTRAK Kinerja merupakan output/outcome dari sesuatu yang telah dikerjakan yang digunakan untuk mengukur tingkat keberhasilan seseorang secara keseluruhan selama kurun waktu tertentu yang dibandingkan dengan standar hasil kerja, target atau sasaran yang telah ditentukan dan disepakati bersama. Penelitian ini menganalisis struktur audit, role conflict (konflik peran), role ambiguity (ketidakjelasan peran) terhadap kinerja auditor intern pemerintah dimana role overload (kelebihan beban kerja) sebagai variabel pemoderasi. Populasi dalam penelitian ini adalah auditor intern pemerintah yang tergabung pada Tim Penilai Gabungan Angka Kredit Auditor yang terdiri atas Arsip Nasional Republik Indonesia, Badan Pengawas Tenaga Nuklir, Lembaga Sandi Negara, Kementerian Pemberdayaan Perempuan dan Perlindungan Anak serta Kementerian Koordinator Bidang Pembangunan Manuasia dan Kebudayaan. Teknik pengambilan sampel menggunakan teknik sampling jenuh (sensus). Structural Equation Model (SEM) dengan program WarpPLS 4.0 digunakan untuk menguji hipotesis yang diajukan. Hasil Penelitian menunjukkan bahwa struktur audit berpengaruh positif terhadap kinerja auditor intern pemerintah, sedangkan konflik peran dan ketidakjelasan peran tidak berpengaruh terhadap kinerja auditor intern pemerintah serat role overload bukanlah variabel yang dapat memoderasi hubungan struktur audit dengan kinerja auditor intern pemerintah.
