“…Indonesia memiliki lebih dari lima ratus jenis rumput laut [1], diantaranya yang bernilai ekonomis adalah alga merah (Rhodophyceae) sebagai penghasil agar dan karagenan,sedangkan algacoklat (Phaeophyceae) sebagai penghasil alginate [2]. Umumnya jenis rumput laut merah yakni Eucheuma cottonii yang dibudidayakan di provinsi Maluku [3] dan merupakan komoditas eksport yang potensial dalam meningkatkan kesejahteraan masyarakat pesisir [4].Produksi rumput laut kering di Maluku tahun 2022 meningkat sebesar 24,5% dari tahun sebelumnya [5], dimana permintaan rumput laut terus meningkat sebesar 5-10% untuk memenuhi industri dalam negeri dan eksport [6]. Tingginya kadar air rumput laut basah 93% [7], sedangkan kadar air rumput laut kering yang distandarkan oleh SNI maksimum 30% untuk Eucheuma cottonii [8].Pengeringan rumput laut merupakan proses pascapanen hasil produksi yang paling kritis sebelum dapat digunakan dalam industry pengolahan [9], Dimana pengeringan melibatkan introduksi perpindahan panas dan massa secara simultan guna menghilangkan molekul air dari produk selama proses pengeringan [10],namun menghilangkan molekul air selama proses pengeringan membutuhkan sejumlah besar energi panas laten yang tinggi [11].…”

Abstrak Penelitian ini berfokus pada penerapan tube bak staggered heat exchanger sebagai sistem pemulihan limbah panas untuk memanfaatkan limbah panas dari pengering konveksi pada suhu < 55°C. Penelitian ini bertujuan untuk mendapatkan masukan panas yang efektif dan memaksimalkan efisiensi untuk mempersingkat waktu pengeringan dan menghemat konsumsi daya. Metode penelitian eksperimental adalah dengan mengubah nilai masukan panas dari 400W menjadi 800W pada kondisi kecepatan angin 2 m/s, suhu media pengering 50°C, dan kelembaban relatif konstan 30% pada kondisi pengoperasian sebelum dan sesudah penggunaan pemulihan limbah panas. Mengambil data berupa suhu, kecepatan udara, kelembaban relatif, dan masukan panas setelah kondisi tunak tercapai. Hasil percobaan menunjukkan bahwa efisiensi menurun seiring dengan bertambahnya masukan panas, pada kondisi operasi sebelum dan sesudah penerapan waste heat recovery, efisiensi maksimum pada masukan panas 400 W masing-masing sebesar 59,54% dan 62,61%. Waktu pengeringan minimum rumput laut adalah 1035 dan 975 menit pada input panas 800W masing-masing pada kondisi sebelum dan sesudah penerapan pemulihan panas limbah. Penghematan daya maksimum pada input panas 400 W adalah 414 KWh atau 1,52 %. Hasil penelitian menunjukkan bahwa pengering konveksi dengan fungsi waste heat recovery dapat digunakan untuk mengeringkan rumput laut, pada kondisi operasi masukan panas 400 W efisiensi sebesar 62,61%, waktu pengeringan 1140 menit, dan penghematan daya sebesar 414 KWh atau 1,52 %

“…There are two types of seaweed cultivated in Bantaeng Regency, namely Eucheuma cottonii and Eucheuma spinosum [5]. Both types of seaweed are types of seaweed that are cultivated in the sea to produce carrageenan [6]. Carrageenan is widely used as a thickener, stabilizer, emulsifier, adhesive, and suspending agent in non-food products such as cosmetics, textiles, paints, and medicines.…”

One of the valuable compounds contained in seaweed is carrageenan, which is found in Eucheuma cottonii and Eucheuma spinosum, the most common species found in Bantaeng Regency, Indonesia. This study aims to measure the quality of carrageenan in those Eucheuma and elaborate on seaweed export regulations in Indonesia. The method used is KCl precipitation, where analysis is carried out on the yield value, moisture and ash content, and pH of carrageenan with reference to the Food and Agriculture Organization (FAO) standards. While the rules for export permits will be explained qualitatively using a statutory approach. The findings showed that the amount of moisture and ash content that met FAO standards was found in Eucheuma cottonii, and it also had the highest yield value. Furthermore, in terms of export permits, exporters need a certificate of origin for seaweed, which is regulated in the Regulation of the Minister of Maritime Affairs and Fisheries No. 7/PERMEN-KP/2013, which aims to provide legal certainty regarding product quality for both exporters and importers. This study recommends that it is required to vary the concentration of the KOH solution used to soak the seaweed in order to obtain a pH of carrageenan that meets FAO standards.

Utilizing mechanical rotary and sieve separators to collect salt particles from the surface of dried Eucheuma cottonii represents an innovative methodological approach. In this study, a mechanical rotary separator was employed to separate impurities like salt particles, mud, stones, and seaweed chunks from the surface of the dried Eucheuma cottonii. Following that, a multi-layer vibro sieve separator was employed to separate the salt particles from impurities. This study aimed to investigate the influence of the separation duration in both equipment for separating impurities on the surface of the dried Eucheuma cottonii, and collecting salt particles from the impurities. Mass balance is utilized to calculate, quantify, and analyze the distribution of impurities mass throughout the entire process line. Impurities produced during the process were characterized using a binocular stereo microscope (Olympus SZ30). The sodium content in the salt particle produced was analyzed using the titration method. The study showed that using a mechanical rotary separator for about 3 minutes on 500 grams of dried Eucheuma cottonii generated 7.6 grams of impurities. Using the multi-layer vibro sieve separator, only 3.8 grams of the initial 7.6 grams of impurities were identified as uncontaminated salt particles. As a result, these salt particles contain a minimum of 60% sodium chloride, presenting a viable alternative to table salt as a low-sodium source. This research demonstrates a significant contribution through its effective methodology for extracting salt particles from dried Eucheuma cottonii, indicating its potential as a viable source of low-sodium salt.
