Abstract

Abstrak---Pada makalah ini dibahas tentang implementasi system transport Packet Abis over IP denganProtokol Ethernet,untuk meningkatkan kapasitas transmisi pada jaringan GSM serta pengaruhnya terhadappeningkatan kualitas jaringan GSM. Implementasi system transport Packet Abis over IP dengan ProtokolEthernet ini dilakukan untuk mengatasi keterbatasan kapasitas transmisi pada system transport Legacy Abisyang menerapkan sistem pengkanalan dengan satuan E1. Metode implementasi Packet Abis over IPdenganProtokol Ethernet pada GSM dilakukan melalui proses migrasi dari sistem transport yang sebelumnyamenggunakan Legacy Abis menjadi Packet Abis over IP dengan Protokol Ethernet. Setelah dilakukanimplementasi system transport Packet Abis over IP dengan Protokol Ethernet pada ketiga site target yangberada di area Jawa Timur, terjadi peningkatan kapasitas transmisiyang sebelumnya 2048 Kbps menjadi 3000Kbps. Selain itu kualitas jaringan GSM meningkat pula, hal terlihat dengan terjadinya throughput improvementsebesar 24.75% pada site 630274_STIKRIAN, 35.4% pada site 630237_STORAMBE dan 32.64% pada site630439_KRAMATJEGU.

Abstract

Feed is a primary factor influencing the growth and survival of pearl catfish larvae, therefore innovation in alternative feed that is efficient and highly nutritious is required. This study aims to analyze the effect of feeding paste made from golden snail flour (Pomacea canaliculata) at different percentages on the growth and survival of African catfish larvae (Clarias gariepinus). The method used was an experimental design with a Completely Randomized Design (CRD), consisting of three feeding treatments (5%, 10%, and 15% of biomass weight) with five replications, conducted over a 30-day rearing period. The observed parameters included survival rate (SR), absolute weight growth, absolute length growth, average daily growth (ADG), specific growth rate (SGR), and water quality. Data were analyzed using Analysis of Variance (ANOVA), followed by the Least Significant Difference (LSD) test at a 5% significance level. The results showed that different feeding percentages had a highly significant effect (p > 0.05) on all parameters. The best treatment was obtained at a feeding rate of 10% of biomass weight, with a survival rate of 96.4%, absolute weight gain of 24.6 g, absolute length gain of 4.56 cm, ADG of 0.41 g/day, and SGR of 70%. Water quality during the study remained within optimal ranges, with temperatures of 24–27°C and pH levels of 7.8–8.5. Thus, feeding paste made from golden apple snail flour at 10% of biomass weight is the optimal dosage to improve the growth and survival of pearl catfish larvae.
