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.

Waste management is still defined as limited to collection, transportation and garbage disposal. The follow-up of the meaning is the provision of facilities such as garbage bins, garbage trucks and waste collection land. Waste management has not included waste separation. Segregation of waste can minimize the amount of waste that must be discharged to the final place. Segregation of waste can supply recyclable raw materials and handicrafts made from garbage. The manufacture of handicraft products from garbage is still local and requires socialization and training. It is needed to increase the number of craftsmen and garbage absorption on the crafters. Through careful socialization and training, citizens' awareness of waste management becomes advanced by making handicrafts of economic value from waste materials.

AbstractThe increase in the world population leads to rising demand and consumption of plastic raw materials; only a small percentage of plastics is recovered and recycled, increasing the quantity of waste released into the environment and losing its economic value. The plastics represent a great opportunity in the circular perspective of their reuse and recycling. Research is moving, on the one hand, to implement sustainable systems for plastic waste management and on the other to find new non-fossil-based plastics such as polyhydroxyalkanoates (PHAs). In this review, we focus our attention on Tenebrio molitor (TM) as a valuable solution for plastic biodegradation and biological recovery of new biopolymers (e.g. PHA) from plastic-producing microorganisms, exploiting its highly diversified gut microbiota. TM’s use for plastic pollution management is controversial. However, TM microbiota is recognised as a source of plastic-degrading microorganisms. TM-based plastic degradation is improved by co-feeding with food loss and waste as a dietary energy source, thus valorising these low-value substrates in a circular economy perspective. TM as a bioreactor is a valid alternative to traditional PHA recovery systems with the advantage of obtaining, in addition to highly pure PHA, protein biomass and rearing waste from which to produce fertilisers, chitin/chitosan, biochar and biodiesel. Finally, we describe the critical aspects of these TM-based approaches, mainly related to TM mass production, eventual food safety problems, possible release of microplastics and lack of dedicated legislation.

In this study polyurethane (PU) residues were mixed with residues of textile fibers (cotton, wool and synthetic fibers up to 70 wt/wt) to produce 100% recycled composites. In addition, the effect of the type of fiber on the performance of the ensuing composites was evaluated. The presence of fibers showed similar effect on the density, reducing the density in the 5.5-9.0% range. In a similar manner, the addition of fillers decreased their thermal conductivity. The 70 wt/wt wool composite presented 38.1% lower thermal conductivity when compared to the neat matrix, a reduction that was similar for the other type of fibers. Moreover, the presence of fillers yields stiffer materials, especially in the case of the Wool based composites, which with 70 wt/wt of filler content increased the tensile modulus of the ensuing material 3.4 times. This was attributed to the aspect ratio and stiffness of this type of fiber. Finally, the high-water absorption and lower thermal stability observed, especially in the case of the natural fibers, was associated with the hydrophilic nature of fibers and porosity of composites. Overall, the results suggest that these textile-based composites are suitable for construction and automotive applications, with the advantage of being produced from 100% recycled raw-materials, without compromised performance.

Increasingly, raw materials of natural origin are used as fillers in polymer composites. Such biocomposites have satisfactory properties. To ensure above-average functional properties, modifications of biofillers with other materials are also used. The presented research work aimed to produce and characterize elastomeric materials with a straw-based filler and four different types of montmorillonite. The main research goal was to obtain improved functional parameters of vulcanizates based on natural rubber. A series of composites filled with straw and certain types of modified and unmodified nano-clays in various ratios and amounts were prepared. Then, they were subjected to a series of tests to assess the impact of the hybrids used on the final product. It has been shown that the addition of optimal amounts of biofillers can, inter alia, increase the tensile strength of the composite, improve damping properties, extend the burning time of the material and affect the course of vulcanization or cross-linking density.

The economic value of volunteering is an increasingly important part of volunteering management. It has become part of public policies. Some requests for proposals (RFP) enable nonprofits to include the value of volunteer time in compulsory co-financing. These RFP include the European Economic Area (EEA) Grants and Norway Grants. This article addresses the relationship in the value of volunteering, also called in-kind volunteering contributions. The research includes two case studies of finances from EEA and Norway Grants in the Czech Republic: the Czech NGO Programme, responsible for allocating grants between 2009 and 2014, and the Active Citizens Fund, responsible for allocating grants between 2014 and 2021. They share elements through the EEA and Norway Grants rules. However, they use different types of specialist replacement wages. The article summarizes the arguments for including in-kind volunteering contributions. It presents the possible values of these contributions in the selected cases, including the relationship between the type of volunteering and the number of hours necessary to achieve these values. The article defines the theoretical basis for calculating the value of in-kind volunteer contributions and illustrates this with real examples of allocations from EEA and Norway Grants.

If a catalogue were made of terms commonly used to affirm the adequacy of critical interpretations of works of art, one word certain to be included would be “plausible.” Yet this term is one which has received precious little attention in the literature of aesthetics. This is odd, inasmuch as I find the notion of plausibility central to an understanding of the nature of criticism. “Plausible” is a perplexing term because it can have radically different meanings depending on the circumstances of its employment. ln the following discussion, I will make some observations about the logic of this concept in connection with its uses in two rather different contexts: the context of scientific inquiry on the one hand, and that of aesthetic interpretation on the other. In distinguishing separate senses of “plausible,” I shall provide reason to resist the temptation to imagine that because logical aspects of two different types of inquiry—science and criticism—happen to be designated by the same term, they may to that extent be considered to have similar logical structures.
