Negative Characteristic

Vinasse, which is commonly referred to as stillage, is a aqueous by-product of bioethanol processing. This side-product is yielded in a very large quantity in bioethanol industry since the production of 1 L of ethanol will generate 13 L of vinasse. Hence it is become a problem of bioethanol industry since vinasse waste doesnt have economic value and it is harmful to the environment. This industrial waste has high COD and BOD, high acidity, and high temperature when it is discharged from the bottom of distillation unit. To overwhelmed this drawbacks, it is crucial to attempt reduction of the negative characteristic of vinasse as well as creation of added value of vinasse. In fact, vinasse contains a considerable amount of potassium and organic matter which is beneficial for plant growth and improving the soil fertility. Thus, in this work, vinasse was utilized as raw material for organic fertilizer. Vinasse waste was formulated with other sugarcane industrial waste (filter cake and boiler ash), and NPK fertilizer in various composition to yield solid Organo-Mineral Fertilizer (OMF). Among all the composition of OMF, It was demonstrated that vinasse formulated with 3, 6, and 9% of NPK fulfilled the Indonesian National Standar (SNI) of solid fertilizer. Thus these types of OMF were used to fertilize tomato plant. The effects of vinasse-based OMF on some growth indices of tomato plant were examined. It was revealed that vinasse fertilizer formulated with 9% of NPK exhibited the best impact to the tomato plant growth.

Potential and opportunities for cassava development are still very broad along with development of companies in livestock, processed food, and other industries. Added value of cassava commodities resulting from development of downstream industries (processed products) is far higher than upstream industries (primary products), so that development paradigm in agriculture sector in future should be directed towards product expansion including its waste. This study aims to examine the economic value of cassava as a future crop from direct as well as by-products and their development strategies. Data was collected from small-scale tapioca flour farmers, ranchers and entrepreneurs. SWOT analysis was used to determine relevant development strategies. Analysis shows that cassava has an potential, especially as a raw material for food and feed industry. In short term, developing cassava strategy as an industrial raw material is to use new technologies i.e. varieties and cultivation techniques for planting arrangements. Cassava potential economic value is relatively high in terms of farming aspects, food raw materials, feed and industry. This potential, apart from main product, is also by-product that has been neglected at 29.7% of cassava main value. By-products potensial has not been used optimally and a bioeconomic value of biomass that can support integrated agriculture in the future.

Purbalingga mempunyai keunggulan ketersediaan kayu yang tinggi, kondisi tanah yang kebanyakan pegunungan sangat mendukung tumbuhnya kayu keras, hampir setiap desa memiliki jumlah tanaman keras yang melimpah. Beberapa perusahaan kayu lapis dan mebelair juga banyak menginvestasikan dibidang produksi kayu lapis dan barecore di beberapa kawasan di purbalingga. UKM mebelair, kayu lapis dan kusen membutuhkan tenaga kerja yang cukup banyak, tidak membutuhkan pendidikan formal, sehingga terbuka pengentasan tenaga kerja secara umum. UKM pengrajin mebelair dan kusen kayu di Desa Sangkanayu, Kecamatan Mrebet, Kabupaten Purbalingga, membuat model berdasarkan pesanan lokal, tidak mengikuti trend furniture terbaru, memiliki kesulitan pada pembentukan model radius dan lengkung, finishing kurang halus dan waktu yang lama. Kayu dengan lubang dan tidak simetris biasanya tidak digunakan sebagai produk kusen/furnitur, limbah kayu dalam bentuk potongan secara umum tidak dimanfaatkan, padahal volume kayu limbah pada pembentukan mencapai kurang lebih 30% dari bahan baku. UKM mebelair belum memiliki pengetahuan pembentukan kayu dari limbah untuk menjadi produk kerajinan. Disamping itu pengetahuan manajeman usaha, pengelolaan keuangan, dan metode pemasaran produk juga masih rendah hanya menunggu pelanggan, mengakibatkan UKM sulit berkembang, persaingan harga antar UKM. Permasalahan pembentukan dengan menggunakan limbah kayu dan bahan baku dalam bentuk potongan digunakan untuk pembuatan kerajinan. Pembentukan ditingkatkan dengan kemampuan untuk membentuk lengkung menggunakan cutting vertical/bendsaw, untuk percepatan pembelahan menggunakan mesin TTG circle cutting. Teknologi yang diterapkan untuk pemanfaatan limbah kayu akibat kerusakan lobang, tidak lurus, akan diubah menjadi produk bernilai ekonomis tinggi, unik dengan epoxy wood resin. Metode pembentukan produk kusen dan mebelair dari kayu (limbah) akan memberikan alternatif untuk meningkatkan nilai tambah dan pendapatan, keuntungan lainnya penggunaan epoxy juga meningkatkan daya tahan, anti rayap dan bernilai ekonomis tinggi, berpotensi memiliki brand merk yang khas. Untuk penguatan manajemen, UKM dikenalkan administrasi keuangan, dan strategi pemasaran produk secara online. Solusi diatas diharapkan akan meningkatkan daya saing dan produktifitas UKM, desain produk baru dengan memanfaatkan limbah kayu untuk menjadi produk dinding kayu, dan produk epoxy wood resin, akan meningkatkan pendapatan UKM.Kata kunci: epoxy wood resin, wooden wall, circle rotary.AbstractPurbalingga has the advantage of high wood availability, the condition of the land that is mostly mountainous strongly supports the growth of hardwood, almost every village has an abundance of perennials. Several plywood and furniture companies also invested heavily in the production of plywood and barecore in several areas in Purbalingga. Furniture furniture, p lywood and sills need a lot of workforce, do not need formal education, sothere is a general elimination of labor. UKM of furniture and wood frame craftsmen in Sangkanayu Village, Mrebet Subdistrict, Purbalingga Regency, make a model based on local orders, do not follow the latest furniture trends, have difficulty in forming radius and curved models, less smooth finishing and long time. Holey and asymmetrical wood is usually not used as a frame / furniture product, wood waste in the form of pieces is generally not utilized, even though the volume of waste wood at the formation reaches approximately 30% of the raw material. Mebelair UKM has no knowledge of wood formation from waste to become handicraft products. Besides that, business management knowledge, financial management, and product marketing methods are also still low, just waiting for customers, which makes it difficult for SMEs to develop, price competition among SMEs. The problem of formation by using wood waste  and raw materials in the form of pieces is used for making crafts. Formation is enhanced by the ability to form curves using vertical cutting/bendsaw, for acceleration of cleavage using circle cutting machine. The technology applied to the utilization of wood waste due to damage to the hole, not straight, will be converted into high economic value products, unique with epoxy wood resin. The method of forming frame and furniture products from wood (waste) will provide an alternative to increase added value and income, other benefits of using epoxy also increase durability, anti termites and high economic value, potentiallyhaving a distinctive brand brand. To strengthen management, SMEs are introduced to financial administration, and online product marketing strategies. The above solution is expected to improve the competitiveness and productivity of SMEs, the design of new products by utilizing wood waste to become wood wall products, and epoxy wood resin products, will increase the income of SMEs.

Worldwide breweries are known to use large volumes of water. Between 10 and 20m3 of water yields 1m3 of beer. This translates to over 90% of wastewater. The world produced 1.94x108m3 of beer in 2018. Of the total production 1.48x107m3 of beer were produced from Africa with Uganda contributing up to 4.1x105m3. Uganda’s major producing industries being Uganda Breweries Limited and Nile Breweries Limited. Uganda’s brewery sector generates between 3.69x106 to 7.79x106m3 of wastewater annually that could otherwise be of importance. This wastewater is characterized by high organic matter content with COD, BOD and TSS ranging between 2,000 to 10,000mg L-1, 1,200 to 7,000mg L-1 and 2,901 to 3,000mg L-1 respectively. Whereas little information has been published regarding the current use of wastewater in Uganda by the Key players, elsewhere in the world the wastewater has been treated for re-use using Anaerobic Sequencing Batch Reactor and membrane bioreactors, for electricity generation using microbial fuel cell and for biogas production using Veolia Bio Bed Technology. The generated sludge has successfully been used as an Organic Fertilizer and a raw material for Organic Fertilizers production in different parts of the world. The process by-products such as spent grain, spent hops and surplus yeast have been used majorly in fertilizers and animal feeds. The purpose of this review article was to explore potential uses of the wastewater in that could apply for Uganda.

<p>The aim of this study was to find a solution on revitalization of the biodiesel plant of 6 tons/day capacity in Serongga, Klumpang Hilir Sub-district, Kotabaru District at Province of South Kalimantan that managed by the Local Government of Kotabaru. Based on the surveys, the biodiesel plant has not worked properly for 3 years since the last commissioning. The reasons for the biodiesel plant not operating were caused by technical, management and economic problems. This paper studied the technical problem, calculation of the estimation cost for repair, replacement and installation of equipments and instruments, analysis of Strength, Weakness, Opportunity and Treat (SWOT), and analysis of economic feasibility in the operation of biodiesel plant. Based on the SWOT Analysis, it was found that the operation of biodiesel plant was strongly influenced by the security of supply and price of raw material, local government efforts to penetrate the market, and increased added-value of by-product. To increase the economic value of the plant in the future, a review on the economic and sensitivity analysis of several options was conducted. The available solutions were to revitalize the plant and operate the plant at the existing location (Scenario 0), to integrate biodiesel plant into a nearby palm oil mill (Scenario 1) and to move the plant at the mining site (Scenario 2). Economic calculation analysis results that integrating biodiesel plant with palm oil mill nearby was the best option (Scenario 1). Based on sensitivity analysis of Scenario 1, financial margin was strongly influenced by the CPO, methanol and biodiesel prices</p><p><strong>Keywords:</strong> Biodiesel Plant, Revitalization, SWOT, Economic Analysis, Integration <br /><br /></p>

AbstractThe Colombian industrial sector is moving toward alternative forms of treatment of industrial waste, considering that the waste can be a source of raw material in the production chain. Thus, aiming at the decrease in mineral fertilizer use, and maintaining or even raising the crop yield, the sugarcane industry has recently advanced in the composting of the industrial waste and application in the field, both of them being potentially sustainable practices. This manuscript reports the economic benefits and the greenhouse gas (GHG) emissions related to the sugarcane production system in Colombia that has been simulated in this study to evaluate the beneficial effects of reusing industrial waste from ethanol production. This study was performed using the Virtual Sugarcane Biorefinery (VSB) modeling software for the simulation of agricultural and industrial parameters on integrated alternatives for the sugarcane industry. Colombian sugarcane sector was modeled using three scenarios representing agricultural systems that do not use composted industrial waste vs a paired scenario for each condition where composted waste is utilized. Regarding compost and vinasse use as fertilizer and soil conditioner, GHG emissions from the biogenic origin are not included as a reported item in the matrix of GHG emissions of the sugarcane sector. Inputs for the economic and environmental assessment models are based on actual operational data from two mill sites, one located in the traditional sugarcane production region of Cauca River Valley and the other one, on the agricultural expansion region of Llanos Orientales. Here, we have found that the reuse of composted industrial waste is beneficial and provides an economic cost savings of 2–6% per year. However, it also results in an annual increase of 10–20% in the GHG emissions.
