Novita Ayu Rahmadani. 26010118130070. Analisis Tingkat Pemanfaatan Ikan
Petek (Leiognathus equulus) yang Didaratkan di PPI Tambak Lorok, Kota
Semarang. (Abdul Ghofar dan Anhar Solichin).
Ikan petek (Leiognathus equulus) adalah salah satu ikan demersal yang
termasuk hasil tangkapan alat tangkap arad. Ikan petek memiliki nilai ekonomis dan
didaratkan di PPI Tambak Lorok dalam jumlah yang cukup banyak. Penelitian ini
bertujuan untuk mengetahui struktur ukuran, hubungan panjang-berat, Lcc50%,
parameter pertumbuhan, laju mortalitas dan tingkat pemanfaatan ikan petek.
Penelitian ini dilaksanakan pada bulan April – September tahun 2021 di PPI
Tambak Lorok, Kota Semarang. Metode penelitian menggunakan metode survei
dengan pengumpulan data panjang total (mm) dan bobot (gram). Analisis data
menggunakan metode ELEFAN I pada FISAT II. Hasil penelitian diketahui bahwa
kisaran panjang ikan petek yaitu 45 – 120 mmTL dengan Lcc50% sebesar 69,5
mmTL. Persamaan hubungan panjang-berat ikan petek yaitu
W=0,00003359L2,854587616 dengan pola pertumbuhan allometrik negatif.
Pertumbuhan ikan petek diketahui persamaan von Bertalanffy yaitu Lt =126,5[1-e
-
1,6(t+0,065227)], dimana pertumbuhannya tergolong cepat. Mortalitas total (Z) ikan
petek sebesar 5,84/tahun, mortalitas alami (M) sebesar 1,65/tahun, mortalitas
penangkapan (F) sebesar 4,19/tahun, dan nilai tingkat pemanfaatan (E) sebesar
0,72. Status tingkat pemanfaatan ikan petek menunjukkan kategori over exploited
dengan nilai E > 0,50.

ABSTRACT
Novita Ayu Rahmadani. 26010118130070. Analysis of The Utilization Rate of
Common Ponyfish (Leiognathus equulus) landed at Tambak Lorok Fishery Landing
Base, Semarang City. (Abdul Ghofar dan Anhar Solichin).
Common Ponyfish (Leiognathus equulus) is one of the demersal fishes that
includes the catch of arad fishing gear. Common Ponyfish has economic value and
it landed in Tambak Lorok Fishery Landing Base in large quantities. The purposes
of this research were to find out the size structure, length-weight relationship,
Lc50%, growth parameters, mortality rate and exploitation rate of Common
Ponyfish. This research was conducted in April - September 2021 at Tambak Lorok
Fishery Landing Base, Semarang City. This research method used survey methods
with data collection of total length (mm) and weight (gram). Data analysis has been
used the ELEFAN I method in FISAT II. The results of the study found that the long
range of Common Ponyfish was 45 - 120 mmTL with Lcc50% was 69.5 mmTL. The
length-weight relationship formula of Common Ponyfish was W =
0.00003359L2.854587616, with a negative allometric growth pattern. The growth of
Common Ponyfish is known to be von Bertalanffy formula that was Lt = 126.5[1-e
-
1.6(t+0.065227)], which the growth was relatively fast. Total mortality (Z) Common
Ponyfish was 5.84/year, natural mortality (M) was 1.65/year, fishing mortality (F)
was 4.19/year, and utilization rate value (E) was 0.72. The utilization rate status of
Common Ponyfish indicated an over exploited category with an E value > 0.50.
