Abstract

Cacing sutera (Tubifex sp.) merupakan pakan alami yang banyak digunakan pada kegiatan pembenihan ikan. Cacing sutera ini mampu memberikan nutrisi yang baik bagi pertumbuhan larva ikan dengan ukuran yang sesuai bukaan mulut larva dan bersifat atraktif. Namun, ketersediaan populasi cacing sutera sangatlah terbatas di alam dan membutuhkan pasokan cacing sutera dari kegiatan kultivasi cacing sutera. Penelitian ini bertujuan untuk mengevaluasi kombinasi kotoran burung puyuh (K), susu bubuk afkir (S) dan tapioka (T) terfermentasi pada media kultivasi cacing sutera. Metode penelitian ini adalah eksperimental laboratorium dengan Rancangan Acak Lengkap Non-Faktorial dengan 4 (empat) taraf perlakuan dan 3 (tiga) kali ulangan. Taraf perlakuan penelitian terdiri atas A (K = 100%), B (K=50%, S=35%, T=15%), C (K=50%, S=25%, T=25%), D (K=50%, S=15%, T=35%). Tahapan penelitian terdiri atas persiapan bibit cacing sutera, aktivasi EM4 dalam fermentasi kombinasi kotoran burung puyuh, susu bubuk afkir, dan tapioka, persiapan media kultivasi cacing sutera, penebaran benih cacing sutera dan pemeliharaan. Hasil penelitian menunjukkan bahwa pertumbuhan populasi, biomassa dan kandungan nutrisi serta rasio C/N terbaik diperoleh pada perlakuan C dengan puncak populasi 406 individu/wadah, biomassa 33,21 g/wadah, nutrisi protein dan lemak sebesar 51,7 ± 0,42% dan 14,56 ± 0,028%, dan rasio C/N 12,5:1. Rekomendasi hasil penelitian ini adalah kombinasi kotoran burung puyuh 50%, susu bubuk afkir 25%, dan tapioka terfermentasi 25% memberikan nutrisi yang paling baik untuk kultivasi cacing sutera.

Abstract

The aim of this research is to find out the influence of working capital turnover and sales growth on profitability in non-cyclical consumer companies listed on the Indonesian Stock Exchange (IDX) for the 2020-2022 period. This research was conducted using a quantitative method approach in the form of numbers and analyzed using statistics. The scope of the research took non-cyclical consumer companies listed on the Indonesia Stock Exchange, totaling 125 companies and the sample used was 46 companies with a sampling technique using Purposive Sampling, namely only taking samples from parts that were directly related to the research. Analysis using multiple linear regression. The results of the partial hypothesis testing research showed that working capital turnover had no effect on profitability, the second result was that there was an influence of sales growth on profitability, and the results of the simultaneous test showed that working capital turnover and sales growth had a simultaneous influence on profitability in consumer companies. non-cyclical listed on the Indonesia Stock Exchange for the 2020-2023 period.
