Keripik tempe adalah salah satu makanan khas di Indonesia. Tujuan penelitian ini yaitu: mengetahui pengaruh cara perekatan dan ketebalan pengemas terhadap mutu keripik tempe, dan mengetahui umur simpan keripik tempe berdasarkan cara perekatan pengemas dan ketebalan pengemas. Faktor yang diteliti yaitu, cara perekatan: stapler, lilin, dan sealer, jenis pengemas: plastik polipropilen 0,07 mm dan plastik polipropilen 0,04 mm, dan lama penyimpanan: 10 hari, 20 hari, dan 30 hari. Hasil penelitian menunjukkan bahwa keripik tempe dengan kemasan plastik polipropilen 0,07 mm dan perekat sealer memiliki mutu paling baik. Selama penyimpanan terjadi peningkatan kadar air, kadar asam lemak bebas, dan kadar peroksida serta terjadi penurunan semua variabel sensorik, tetapi keripik tempe kemasan plastik polipropilen 0,07 mm dengan perekat sealer mampu mempertahankan mutu keripik tempe sampai hari ke-30, sedangkan perlakuan lainnya hanya mampu sampai hari ke-20.

This paper proposes an analytical expression set to determine the maximum values of currents and voltages in the Class-E Power Amplifier (PA) with Finite DC-Feed Inductance (FDI) under the following assumptions—ideal components (e.g., inductors and capacitors with infinite quality factor), a switch with zero rise and fall commutation times, zero on-resistance, and infinite off-resistance, and an infinite loaded quality factor of the output resonant circuit. The developed expressions are the average supply current, the RMS (Root Mean Square) current through the DC-feed inductance, the peak voltage and current in the switch, the RMS current through the switch, the peak voltages of the output resonant circuit, and the peak voltage and current in the PA load. These equations were obtained from the circuit analysis of this ideal amplifier and curve-fitting tools. Furthermore, the proposed expressions are a useful tool to estimate the maximum ratings of the amplifier components. The accuracy of the expressions was analyzed by the circuit simulation of twelve ideal amplifiers, which were designed to meet a wide spectrum of application scenarios. The resulting Mean Absolute Percentage Error (MAPE) of the maximum-rating constraints estimation was 2.64%.
