The development of production center areas is included in the concept of developing new areas where the idea of development is based on existing potential. Determination of production centers can be determined by means of regional development of commodities. The seaweed industry is a fast growing seaweed farm in several countries. Seaweed currently produces large-scale production, generally for food, feed, biofuels and biochemicals, so it requires a production center area to meet consumer needs. The strategic role of agro-industry which is based on increasing the potential added value of domestic natural resources is believed to be able to support the increase in the nation's competitiveness, especially for the seaweed commodity.

Pertanian rumput laut berkembang cepat terutama pada industri makanan yang menjadi pemimpin pasar produk rumput laut bernilai tinggi. Rantai pasok rumput laut menghadapi masalah yang kompleks, seperti ketidakstabilan ketersediaan rumput laut yang menyebabkan ketidakmampuan dalam memenuhi kebutuhan pelanggan. Kualitas yang buruk dapat berdampak negatif pada penurunan kepuasan pelanggan jangka panjang. Fluktuasi harga rumput laut juga sangat mempengaruhi profitabilitas yang mengakibatkan hilangnya keuntungan. Keberlanjutan rumput laut untuk kebutuhan masa depan menekankan pentingnya manajemen rantai pasok yang tepat. Penelitian ini bertujuan untuk meninjau pengetahuan tentang manajemen rantai pasok mencakup konsep, metodologi dan objek penelitian. Metode penelitian ini deskriptif kualitatif. Hasil penelitian adalah supply chain management belum menjangkau pengembangan kawasan sentra produksi produk turunan untuk memenuhi ketersediaan bahan baku secara keberlanjutan. Kesimpulannya supply chain management pada agroindustri rumput laut akan berpengaruh kepada pengembangan kawasan sentra produksi, peningkatan kemampuan sumber daya pelaku rantai pasok agroindustri rumput laut, dan ketersediaan bahan baku berupa produk turunan secara berkelanjutan.

CGT-ase enzyme has optimum capability at the temperature of 45C, pH 6.5. yielded 7.864 unit/minute/mL. The pretest of CGT-ase transfer activity was carried out using pyrocatechol and resorcinol as an acceptor and iso-malto and commercial starch solution as the glucosyl donor. Subsequently, acceptor was replaced by flavonoid (Etyl acetate and butanol fraction) extracted from four types of gambir from West Sumatra. Keywords: Uncaria gambir, Bacillus Licheniformis, , flavonoid--glicoside.

The development of coconut agro-industry can increase product added value. Value-added analysis needs to be carried out to find out how much the added value of processed coconut product is. The calculation of basic costs also needs to be done to find out how much it costs to produce 1 unit or 1 kg of product. This research is beneficial as decision support through useful information for coconut farmers in increasing their income. Value-added analysis in this study used the Hayami method, while the calculation of the cost of processing involves fixed costs, variable costs, working hours, and production capacity.

The value of the hydroxyl value is affected by the temperature and time of the oxirane rings opening reaction. The purpose of this study was to examine the combination of temperature and time of the best oxirane rings opening reaction to produce polyols with a hydroxyl value of less than 100 mg KOH/g. Epoxidized palm oil was treated with temperature (50°C, 60°C, 70°C, and 80°C) and time (1 hour, 2 hours, 3 hours, and 4 hours). Parameters observed were hydroxyl value, hydroxyl content, density, viscosity, acid number, and color. The best treatment continued with the FTIR test. The oxirane rings opening reaction using a temperature of 50°C for 1 hour gave a hydroxyl value of 75.87 mg KOH/g.

The existence of a global positive solution, persistence, stability of the equilibria and Hopf bifurcation are studied respectively. By calculating the normal form on the center manifold, the formulas determining the direction and the stability of Hopf bifurcations are explicitly derived. Finally, our theoretical results are illustrated by a model with homogeneous kernels and one-dimensional spatial domain.

The advantages of processing corn cobs into powder include durability, a smaller volume, and lighter weight, making it easier to pack and transport. One of the important steps in making corn cobs powder is drying to determine the durability and quality of the corn cobs powder. This study aimed to determine different drying durations of corncobs powders and their effect on physical, nutritional, and phytochemical properties as an alternative to functional food and foodstuffs. The experimental design used a Completely Randomized Design (CRD), consisting of one factor with four treatments: 4;5;6;7; and 8 hours and four replications.
