Pulp Processing

Seaweed is a commodity which has great potency to be developed and commonly used in food and non-food industry, such as cosmetic and pharmaceutical. Currently, seaweed can also be utilized as raw material for pulp to support an environmental friendly paper industry. Research has been done by scientists from Korea who developed the processing technology of red algae by using extraction and bleaching process. The process is very simple, need less energy and environmental friendly chemical material. Red algae species which is used in this process is Gelidium amansii, which is very suitable for paper industry purposes and can be harvested in around 3 months, therefore this is different with wood pulp. There is a cooperation between Korea and Indonesiain producing Gelidium in Indonesia. This paper presents the assessment of red algae pulp processing technology and examines several matters that should be considered in developing red algae pulp industry in Indonesia. In term of resources, support from the government, universities and research institutions and acceptance of the industry.keywords : seaweed, red algae, extraction, paper, environment

<p>The number of iron sand reserves is mostly spread in the coastal waters of Indonesia, from the coast of Sumatra, the southern of Java to Bali, the beaches of Sulawesi, beaches in East Nusa Tenggara (NTT), and the northern coast of Papua. Total reserves for ore are 173,810,612 tons and metal as much as 25,412,652.62 tons. But its utilization was not optimal because PT. Krakatau Steel, and PT. Krakatau Posco has produced steel plates only 24,000 to 36,000 tons per year. While the need for steel plates for the shipping industry each year requires 900,000 tons per year. With the need for raw material for steel plates in the form of iron sponges with Fe ≥ 60%, PT. Krakatau Steel is still imported from abroad. The proof is PT. Krakatau Steel before and during the year 2000 still imported Iron Ore Pellets from the countries of Sweden, Chille and Brazil for 3,500,000 tons per year. This condition is the cause of the national steel industry unable to compete with the foreign steel industry because imported raw materials are subject to import duties. This is an opportunity to build a steel raw material company because all this time the steel raw material industry in Indonesia has only two companies. This condition encourages the manufacture of iron sponges, with the process of making iron sponges with technology adapted to installed production capacity. This study analysed the manufacture of iron sponges using Cipatujah iron sand, as raw material for the manufacture of iron sponges, with the results obtained in the form of iron sponges with the highest levels of Fe ≥60.44%. This can be used for the purposes of raw materials for steel making PT. Krakatau Steel (PT. KS), because so far PT. KS claims that Fe &lt;60% local sponge iron products. This can encourage the independence of steel raw materials, which impacts on the independence of the defence industry. But the government must also protect and prioritize steel raw materials for national production for national steel production. With the national government steel industry, the consortium of vendors supplying raw material (iron sponge) to maintain the quality and supply of continuous sponge iron.</p><p><strong>Keywords</strong>: iron sand, iron pellet, iron sponge</p>

The paper considers the main components and products of wood processing, agricultural waste, pulp and paper industry waste and qualifies them as sources of pentose-containing resource-renewable domestic raw materials. The article describes in detail the structural components of wood as a natural polymer, which contains aromatic and carbohydrate parts. It is noted that these poly-mers are promising as raw materials for the production of useful chemical products. The role of lignin, cellolose and hemicellulose in the design of mechanical and structural properties of wood is considered. The article considers the features of the sulfonation reactions of the lignin monomer unit depending on the pH of the medium: acidic, neutral and alkaline. There are three main reac-tions that occur simultaneously with lignin in the process of wood delignification during sulfite cooking, such as the sulfonation reaction, the hydrolytic destruction reaction, and the condensation reaction. It is shown that the lignin-hemicellulose matrix contains three types of interconnected mesh structures: the lignin itself; a network of covalent bonds of lignin with hemicelluloses, and a network whose structure is obtained due to the hydrogen bond and the forces of the physical inter-action of lignin and hemicelluloses. The features of chemical transformations of the monomeric aromatic link of lignosulfonate – phenylpropane unit in the processes of wood delignification, the main chemical reactions of wood raw material delignification under the conditions of sulfite and neutral-sulfite brews are shown. The method of quantitative determination of monosaccharides in the composition of the carbohydrate part is proposed.

Soybean is the main crop of the palawija system which is commonly applied in Indonesia. In the national economic system, soybean is a commodity owning strategic values due to its ability to supply nutrients needed by the community and a source of income for farmers. Demand for soybean is likely to continue to increase in line with population growth, increase in per capita income, increase in public awareness of nutritional adequacy, and the development of livestock preparation and silage industries. Given the high trend of soybean demand in the future, efforts to increase domestic soybean production are becoming increasingly important. Meanwhile in the future, the policy to protect domestic soybean farmers will be limited due to the demands of free trade. Considering that soybean is consumed in the form of processed food, the increasing demand for soybeans in the future indicates that there will be more opportunities for the development of home industries to produce this food. The need for soybeans as raw material for agro-industry cannot currently be met by domestic soybean production, both in terms of quality and quantity. This causes the need for imported soybeans to be even greater. Domestic soybean production, both in quality and quantity, seems to be unable to meet the soybean needed for industrial raw materials, thus causing a higher tendency for imported soybean demand. Therefore, import tariff policies in the face of world trade liberalization must be regulated in such a way by taking into account the interests of producers, consumers, and the government. This policy is still needed in realizing the independence of export quality soybeans. Kedelai adalah tanaman utama Sistem Palawija yang umum diterapkan di Indonesia. Dalam sistem perekonomian nasional, kedelai menjadi komoditas yang memiliki nilai strategis karena memiliki kemampuan untuk memasok hara yang dibutuhkan oleh masyarakat dan merupakan sumber pendapatan bagi petani. Permintaan kedelai akan terus meningkat seiring dengan adanya peningkatan jumlah penduduk, pertambahan pendapatan perkapita tiap penduduk, meningkatnya kesadaran masyarakat akan gizi yang cukup, serta berkembangnya industri persiapan dan silase ternak. Melihat masih tingginya trend permintaan kedelai di masa datang, upaya peningkatan produksi kedelai di dalam negeri menjadi semakin penting. Sementara itu di masa depan kebijaksanaan untuk melindungi petani kedelai di dalam negeri semakin terbatas peluangnya karena tuntutan perdagangan bebas. Mengingat sebagaian besar kedelai dikonsumsi dalam bentuk bahan pangan olahan, meningkatnya permintaan kedelai di masa depan menunjukkan semakin terbukanya peluang pengembangan industri rumah tangga untuk memproduksi bahan pangan tersebut. Kebutuhan akan kedelai sebagai bahan baku agroindustri saat ini tidak dapat dipenuhi oleh produksi kedelai dalam negeri baik dari segi kualitas maupun kuantitas. Hal ini menyebabkan kebutuhan akan kedelai impor akan semakin besar. Kedelai yang dibutuhkan untuk bahan baku industri tampaknya tidak dapat dipenuhi oleh produksi kedelai dalam negeri, baik kualitas maupun kuantitasnya, sehingga menyebabkan kecenderungan permintaan kedelai impor semakin tinggi. Oleh karena itu, kebijakan tarif impor dalam menghadapi liberalisasi perdagangan dunia harus diatur sedemikian rupa dengan memperhatikan kepentingan produsen, konsumen, dan pemerintah. Kebijakan ini tetap diperlukan dalam mewujudkan kemandirian kedelai kualitas ekspor.

Industri pulp Indonesia saat ini memiliki masalah dalam penyediaan bahan baku kayu Acacia mangium, karena serangan penyakit tanaman dan hama. Hal ini harus diantisipasi melalui bahan baku alternatif pengganti Acacia mangium, spesies Eucalyptus pellita dipilih karena lebih tahan terhadap hama dan penyakit. Penelitian ini dilakukan untuk mengetahui karakteristik kualitas pulp kraft putih E. Pellita. Penelitian pembuatan pulp kertas dilakukan dengan proses kraft dengan bahan baku A. mangium dan E. pellita. Pemasakan dilakukan dengan variasi alkali aktif 16-20%, sulfiditas 28,7%, pada suhu 165 °C, rasio larutan pemasak terhadap kayu 3,5:1 dan faktor H 1.022. Pemutihan pulp dilakukan dengan proses ECF (Elemental Chlorine Free) dengan tahapan OD0EoD1. Karakteristik pulp kraft hasil pemasakan A. mangium lebih tinggi pada parameter rendemen tersaring, bilangan kappa dan viskositas dibandingkan dengan E. pellita. Penggunaan alkali aktif 16% pada pemasakan A. mangium lebih rendah dari  E. pellita (18%), namun kualitasnya dapat memenuhi spesifikasi kualitas pulp kraft putih sesuai SNI 6107:2015 (Pulp Kraft Putih Kayu daun) pada parameter derajat giling, derajat putih dan sifat fisik.  Karakteristik pulp kraft putih A. mangium lebih tinggi pada parameter derajat giling, derajat putih dan sifat fisik dibandingkan dengan E. pellita. Namun demikian E. pellita berpotensi untuk dikembangkan di Hutan Tanaman Industri sebagai bahan baku pulp.Effect of Active Alkali on Characteristic of Acacia mangium and Eucalyptus pellita Bleached Kraft PulpAbstractThe Indonesian pulp industry currently has problems in supplying Acacia mangium wood raw materials, due to plant disease and pest attacks. This could be anticipated through alternative raw materials to substitute Acacia mangium, the Eucalyptus pellita species chosen because it is more resistant to pests and diseases. This study was conducted to determine the quality characteristics of E. Pellita bleached kraft pulp. The research on making paper pulp using A. mangium and E. pellita was carried out by means of the kraft process. The cooking was carried out with a variation of 16-20% active alkali, 28.7% sulfidity, at a temperature of 165°C, a liquor to wood ratio of  3.5:1 and an H factor of 1.022. The bleaching of the pulp has been carried out using the ECF (Elemental Chlorine Free) process with the OD0EoD1 stage. Characteristics of kraft pulp from A. mangium cooking were higher in the screening yield, kappa number and viscosity compared to E. Pellita. The use of 16% active alkaline in cooking of  A. mangium is lower than E. pellita (18%), but the quality can meet the quality specifications of white kraft pulp according to SNI 6107: 2015 (White Kraft Leaf Wood Pulp) on the parameters of milled degree, whiteness and properties. The characteristics of A. mangium white kraft pulp were higher in parameters of grind degree, whiteness and physical properties compared to E. pellita. However, E. pellita has the potential to be developed in Industrial Plantation Forests as raw material for pulp.

In Islamic law, khamr is a common type of alcoholic beverage that is forbidden for consumption due to its elements that can intoxicate and lead to loss of self-control. The government of Indonesia also forbids people from consuming the intoxicating beverage in certain levels. Nevertheless, a community group in Batu Payuang Halaban, Lima Puluh Kota Regency, West Sumatra Province, Indonesia, wherein their daily lives can be found a type of traditional beverage as same as khamr that is a fermented juice of sugar palm bunches. The people call it “tuak”. This research aims to investigate how the people of Nagari Batu Payuang produce aia niro and tuak, their motives for buying, selling, and consuming the drink, and judging it from the perspective of Islamic law (hadd al-syurb). This type of research is field research with a qualitative approach. Data sources consisted of primary and secondary. The data collection was conducted by observing the process of producing aia niro, tuak, and the transaction, and in-depth interviews with owners of sugar palm plantation, tuak producers, buyers, sellers, consumers, and local ulama (Islamic scholars). The data were analyzed in descriptive by reduction, display, and verification. To examine this research, the theory used was the concept of hadd al-syurb in Islamic law and the regulation on alcoholic beverages in Indonesia. The results show that aia niro is produced by extracting the bunches of male sugar palm and it is the raw material to produce tuak by leaving the aia niro in jerry cans and adding agarwood bark for 3 days. The sellers have various reasons to sell tuak and its raw materials. Besides the price is higher than brown sugar, it is also motivated by personal and other economic reasons as well as easier processing. People who drink tuak realize that it is intoxicating in a certain amount but they drink it to warm their bodies and relieve their fatigues. In the concept of hadd al-syurb, consuming tuak as an intoxicating substance is haram (forbidden) and is condemned to those who drink it. However, they who trade it are not punished by hudud since the Sunna proposition only refers to the transaction as an act of curse.
