Abstract

Penyimpanan bahan makanan bertujuan mencegah pembusukan makanan sehingga shelf life cukup lama, kualitasnya tetap terjaga, dan ketersediaannya berada di sepanjang waktu. Metode penyimpanan dilakukan mulai dari bahan makanan segar (hasil panen), pengolahan, pemrosesan, pengemasan hingga pendistribusian produk. Berdasarkan ketahanannya, makanan terbagi atas makanan tahan lama, semi-tahan lama, dan tidak tahan lama. Beberapa teknologi penyimpanan makanan yaitu penggunaan bahan kimia dan mikroba, pengkontrolan kandungan air, struktur makanan, serta penggunaan panas dan energi, maupun teknologi kombinasi. Penyimpanan makanan tidak tahan lama dapat dilakukan di dalam freezer dikemas secara vakum (ikan dan daging), kulkas (susu), dan iradiasi gamma terhadap potongan sayuran untuk menurunkan jumlah E. coli. Lalu, penyimpanan makanan semi-tahan lama melalui pelapisan kitosan (jambu) menunda kematangan, metode hibrid dan pengeringan tepung jagung, dan kombinasi ethanol emitter dengan penyerap oksigen untuk mengawetkan potongan roti gandum. Sedangkan, penyimpanan makanan tahan lama juga menggunakan iradiasi gamma terhadap kacang mende dan metode pulsed electric mereduksi mikroba pada rempah-rempah.

Abstract

Fungsi bahan pangan saat ini tidak hanya untuk memenuhi rasa lapar saja, tetapi juga digunakan untuk menjaga kesehatan dan kebugaran bagi manusia. Konsumsi nutrisi khususnya protein oleh manusia sangat kurang karena ketersediaan makanan sehat yang kurang serta pola makan manusia yang tidak teratur. Protein adalah zat yang penting bagi manusia, serta bahan pembentuk enzim dan hormon dalam tubuh. Manusia membutuhkan sekitar 1 g protein / kg berat badan per hari. Untuk memenuhi kebutuhan protein, cara alternatif yang digunakan adalah untuk memproduksi makanan fungsional atau suplemen yang mengandung protein tinggi seperti dari ganggang Spirulina sp. Spirulina adalah cyanobacteria berbentuk spiral, memiliki klorofil, dan mengandung protein sekitar 50-70% berat kering, beberapa vitamin dan mineral. Spirulina platensis dapat dibudidayakan pada media air tawar, air payau atau air laut. Untuk kebutuhan obat-obatan dan makanan manusia, Spirulina platensis dibudidayakan di air tawar lebih baik karena memiliki kandungan protein yang tinggi dan kandungan sodium rendah. Spirulina platensis dibudidayakan di media air laut memiliki fikosianin dan karbohidrat yang tinggi, dan memiliki biaya produksi rendah. Spirulina yang dibudidayakan menggunakan media air laut juga cenderung memiliki kandungan natrium tinggi sehingga tidak baik bagi kesehatan. Ulasan ini menggambarkan potensi penggunaan dari Spirulina sebagai sumber protein untuk makanan fungsional. Dalam makalah ini penerapan biomassa Spirulina akan ditampilkan dalam aplikasi makanan dan farmasi.

Abstract

Along with the growth in oil palm output, the amount of trash produced will also increase. Every palm oil mill is responsible for the disposal of liquid waste known as palm oil mill effluent (POME). POME includes very high levels of BOD and COD, which may hinder the development of microalgae. Before POME may be utilized as a medium for the growth and development of microalgae, a detailed investigation is required to establish the pretreatment measures necessary to reduce the BOD and COD levels. The purpose of this investigation of POME waste as a substrate for the growth and development of microalgae is to examine the POME processing procedure utilizing wild microalgae. The experimental technique consisted of adding POME and microalgae to the Erlemeyer in accordance with the required proportion. Research demonstrates that POME pond IV waste may be utilized as a substrate for the development of wild microalgae to lower POME waste BOD and COD levels. The variables used were the ratio of POME to microalgae volume and the quantity of nutrients supplied. Microalgae growth at a ratio of 1:4 produced the greatest decreases in BOD and COD, namely 61.66 ppm and 173.33 ppm from 110.6 ppm and 496.67 ppm, respectively. The impact of adding nutrient C at a concentration of 120 ppm led to the greatest decrease of BOD and COD, namely 65.33 ppm and 186.67 ppm, whereas adding nutrient N at a concentration of 40 ppm led to the greatest reduction of BOD and COD, namely 55.41 ppm and 158.33 ppm.

Abstract

Indonesia and Malaysia are recognized as the world's leading producers of palm oil. Along with the growth of the palm oil industry in Indonesia, the amount of Palm Oil Mill Effluent has increased. Palm Oil Mill Effluent (POME) is a liquid byproduct of the palm oil production process. POME has been treated using aerobic and anaerobic ponds to lower Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) levels, but it still includes nutrients like as C,N,P that are beneficial to the development of microalgae. On this study, Spirulina platensis was grown in POME medium with 20%, 40%, and 60% V. concentrations. Every two days, the nutrients Urea, NaHCO3, and TSP were administered. Seven days of aeration and 24-hour lights are used throughout the cultivation phase. The results indicate that POME with a 20 % concentration is the optimal medium for plant growth. Add 25 ppm Urea, 50 ppm TSP, and 200 ppm NaHCO3 for the optimal nutritional composition. At the same treatment on various medium, the highest growth rate of Spirulina platensis is determined to be µ = 0.128% per day, with an optical density of 0.648. Carbon reductions range from 83.03 % to 84.10 %, while Nitrogen savings range from 78 % to 79.55 % when POME is used as a growing medium. This study also shown that the C, N, and P concentrations of POME fall by 93 to 98 %, 99 to 99.5 %, and 92 to 97 %, respectively.

Abstract

Pengeringan merupakan salah satu proses untuk memperpanjang masa simpan dari bahan yang dikeringkan. Jamur tiram merupakan suatu komoditas yang mempunyai masa simpan yang cukup singkat karena mempunyai kadar air yang cukup tinggi. Untuk memperpanjang masa simpan perlu dilakukan proses pengeringan. Banyak metode pengeringan yang dapat dilakukan untuk mengeringkan jamur tiram. Metode pengeringan dengan memanfaatkan sinar infrared dianggap sebagai metode yang cukup menjanjikan baik dari segi lama proses pengeringan, jumlah energi yang digunakan maupun biaya. Penelitian ini bertujuan untuk melakukan proses pengeringan jamur tiram dengan menggunakan lampu infra dengan menggunakan 3 level daya lampu. Adapun variasi level daya lampu (432 W, 504 W dan 624 W) dan berat bahan yang dikeringkan sebesar 500 gram. Parameter yang diamati meliputi penurunan kadar air terhadap waktu, perubahan temperatur dalam ruang pengering terhadap waktu dan specific energy consumption/SEC (kWh/kg). Hasil penelitian menunjukkan bahwa penurunan kadar air tercepat terjadi pada penggunaan level daya 624 W dimana kadar air tercapai sebesar 7,1% dalam waktu 130 menit. Level daya 624 W juga mencapai temperatur tertinggi sebesar 84°C dalam ruang pengering. Sedangkan specific energy consumption/SEC tertinggi yaitu 3,598 kWh/kg pada penggunaan level daya 432 W.

Abstract

The application of nanocomposite membranes for high organic wastewater treatment faces several problems such as impurities and low permeate flux. In this study, sulfonated ZnO nanoparticles were incorporated in the PSf membrane. SEM images reveal that sZnO has good compatibility with PSf polymers and the FTIR spectrum also forms sulfonic acid groups on the composite membrane. The addition of sZnO into PSf increased the PWF value but overloading caused a significant decrease. The surface hydrophilicity of the membrane was also enhanced by the incorporation of sZnO into the PSf membrane. The performance evaluation showed a significant increase in flux from 9.0 to 14.5 L.m-2.h-1 and a disappointment rate for ammonium ion (NH4+) up to 87%. Increased hydrophilicity was also revealed by decreasing the air contact angle from 79.33° to 55.67°. PVA-coated membranes can increase COD rejection up to ~88%, which is 8 times higher than uncoated composite membranes. The PVA coating also reduced the tendency of organic fouling on the membrane during rubber wastewater filtration by reducing the total fouling resistance from 14.2 x 10-11 to 9.91 x 10-11 m-1. The HAZOP and risk analysis were also studied in this work regarding on their practical application in industrial scale..
