Abstract

The entry of microplastic waste into pond waters come from household and fishing activities. This study aims to identify the presence of microplastics in milkfish in the Pedaleman Village pond by considering the type, color, and size of microplastics and to determine the polymers structure found in the digestive tract of milkfish. A total of 24 samples were collected directly from the pond in March to April 2023. The fish were measured for length (cm) and weight (g), and then dissected to remove the organs including digestive tract and muscle. The organs were then destroyed and microplastics were identified using microscope stereo. The fish organs were destroyed using 10% KOH after wet weight was measured. The sample were incubated for 24 hours until the organic matter was destroyed. Then, filtered using Whattman 42 paper and dried in an oven. The types of microplastics found in milkfish were fibers, films, and fragments. Fragment were the most abundant type of microplastics, followed by fiber and film. The fiber had a variety of colors, while the fragments are only found in black. The types of microplastic polymers found in milkfish intestines were polyethylene (PE), polytetrafluoroethylene (PTPE), Polymethyl methacrylate (PMMA), and nylon.

Abstract

Common carp strain Sinyonya (Cyprinus carpio) is a freshwater fish that has high economic value. The development of fisheries cultivation business has caused an increase in demand for feed and raw materials so that feed prices become uncompetitive. Therefore, it is necessary to find alternative local feed raw materials. Plant protein source that has the potential to be developed is the indigofera (Indigofera zollingeriana) which has a protein content of 28.98‒36.62%, crude fiber 8.49‒17.40%, and fat 3.3%. This study was aimed to evaluate the use of indigofera leaf flour as a feed raw material on the digestibility of common carp. This study applied the completely randomized design experimental method containing four diet treatments and three replications, namely A (control), B (30% non-fermented indigofera leaf meal), C (30% fermented indigofera leaf meal), D (30% soybean meal). Common carp with an average body weight of 5.87±0.90 g were kept in aquariums (60 × 40 × 40 cm3) with a density of 10 fish per aquarium and fed three times a day at satiation for 30 days of maintenance. The results showed that the use of indigofera leaf flour fermented using A. niger mold had a significant effect (p<0.05) on total digestibility with a value of 53.7%, protein digestibility of 84.88% and energy digestibility of 70.60% in common carp. This study also showed that indigofera leaf flour fermented using A. niger mold could reduce crude fiber in feed from 5.21% to 2.98%.

Abstract

Carp is a valuable freshwater fish that thrives in various temperatures and water conditions, making it suitable for cultivation in diverse regions to satisfy community needs for animal protein. However, one of the primary challenges in carp farming is the high cost of commercial feed, which can contribute up to 91.2% of total production expenses. Thus, identifying affordable alternative protein sources is essential. Indigofera zollingeriana, a protein- and amino acid-rich plant, shows potential as an alternative to traditional feed ingredients like soybean meal. This study examines the effectiveness of using Indigofera as a feed ingredient for Sinyonya carp (Cyprinus carpio). The research applied a Completely Randomized Design with 5 treatment groups, each with varying Indigofera zollingeriana concentrations: TDI 0, TDI 25, TDI 50, TDI 75, and TDI 100. Findings revealed that Indigofera-based feed significantly boosted absolute growth and daily growth rate of the fish, although it did not influence feed efficiency or survival rate. The optimal concentration was determined to be TDI 75, or 75% Indigofera. Water quality remained favorable for the fish throughout the study.

Abstract

This research was conducted in Domas Village, Pontang District, Serang Regency, Banten Province, which is a milkfish farming pond. The purpose of this study was to analyze the abundance of microplastic particles in milkfish, identify the characteristics of microplastic particles in milkfish and identify the types of polymers that make up microplastics. This study aims to provide information about microplastics in milkfish in Domas Village which can be used as a development of science about microplastic pollution. The methods used in sampling are purposive sampling and descriptive analysis in identifying microplastics. The results showed that milkfish samples, sediment and water had been contaminated with microplastics of fiber, film and fragments with different abundances at each station. The highest abundance of microplastics in meat organs had a value of 14 particles/ind of film type at station 2, the highest abundance in water came from film type with a value of 5 particles/ml, and the highest abundance in sediment came from film type with a value of 6 particles/g. The results of the FTIR test conducted showed that there were 2 types of polymers, namely polycarbonate (PC) and acrylonitrile butadiene styrene (ABS). Keywords: FTIR; Microplastic; Milkfish

Abstract

Dalam persaingan bisnis, banyak perusahaan yang tampak berdiri sendiri, padahal sebenarnya merupakan gabungan dari beberapa perusahaan yang berbeda. Sebagian dari mereka melakukan kombinasi bisnis seperti merger, akuisisi, dan konsolidasi. Tinjauan ini bertujuan untuk meninjau penelitian sebelumnya tentang pergeseran perlakuan akuntansi untuk kombinasi bisnis, bergerak dari pendekatan yang bervariasi menuju pendekatan yang terstandarisasi oleh PSAK 22 yang merupakan sudah dikonvergensi dengan IFRS. Penelitian ini juga menganalisis lebih dalam mengenai bagimana implementasi penerapan PSAK 22 tentang kombinasi bisnis dalam konteks konvergensi IFRS diterapkan oleh berbagai perusahaan di Indonesia. Penelitian ini menggunakan metode kuantitatif dengan fokus pada tinjauan literatur. Hasilnya menunjukkan belum semua perusahaan mengimplementasikan PSAK 22 terbaru ini dikarenakan sulitnya pengukuran nilai wajar goodwill, kurangnya pengetahuan akademisi akuntansi, sekaligus perbedaan praktik perusahaan diberagam sektor memicu beberapa perusahaan masih belum menerapkan PSAK ini.

Abstract

Penelitian ini bertujuan untuk menganalisis secara empiris pengaruh Penghindaran Pajak, Kualitas Audit, Pertumbuhan Aset, dan Ukuran Perusahaan terhadap Nilai Perusahaan pada perusahaan subsektor makanan dan minuman yang terdaftar di Bursa Efek Indonesia (BEI) selama periode 2020–2024. Studi ini dilatarbelakangi oleh pentingnya nilai perusahaan sebagai cerminan kinerja dan daya tarik investasi di tengah persaingan industri yang semakin ketat serta dinamika kondisi ekonomi pascapandemi. Penelitian menggunakan metode kuantitatif dengan pendekatan asosiatif, memanfaatkan data sekunder yang bersumber dari laporan keuangan tahunan yang dipublikasikan di situs resmi BEI dan masing-masing perusahaan. Populasi penelitian mencakup 95 perusahaan subsektor makanan dan minuman, dengan teknik purposive sampling sehingga diperoleh 53 perusahaan yang memenuhi kriteria sampel. Analisis data dilakukan menggunakan regresi linier berganda dengan bantuan perangkat lunak SPSS versi 22 setelah melalui uji asumsi klasik. Hasil penelitian menunjukkan bahwa Penghindaran Pajak yang diukur dengan Tingkat Pajak Efektif (ETR) berpengaruh positif signifikan terhadap Nilai Perusahaan, mengindikasikan bahwa strategi efisiensi pajak dapat meningkatkan nilai pasar. Sebaliknya, Kualitas Audit yang diproksikan dengan jenis Kantor Akuntan Publik tidak berpengaruh signifikan, sementara Pertumbuhan Aset dan Ukuran Perusahaan berpengaruh negatif signifikan terhadap Nilai Perusahaan. Temuan ini diharapkan dapat menjadi pertimbangan bagi manajemen, investor, dan pembuat kebijakan dalam pengambilan keputusan serta pengembangan strategi keuangan dan tata kelola perusahaan yang lebih efektif di masa mendatang berkelanjutan.
