“…Analisis faktor merupakan cara untuk menyederhanakan kerumitan [7]. Analisis faktor adalah sebuah teknik yang digunakan untuk mencari faktor-faktor yang mampu menjelaskan hubungan atau korelasi antara berbagai variabel independen yang diamati [8]. Pada Tabel 2 dapat dilihat bahwa nilai diagonal yang bertanda a yang tidak memenuhi syarat untuk diuji lanjut adalah yang memiliki nilai di bawah 0,5 yaitu variabel ada wifi, kenyamanan ruang tunggu, iklan dan promosi.…”

Pada masa pandemic covid-19 sejak akhir tahun 2019 hingga tahun 2022 sekarang telah terjadi banyak pemutusan hubungan kerja secara sepihak yang dilakukan oleh banyak perusahaan yang bergerak di bidang jasa. Hal ini terjadi sebagai akibat dari turunnya laba perusahaan yang berujung pada pemecatan karyawan terutama bisnis yang banyak menggunakan sentuhan kontak fisik secara langsung terhadap konsumen seperti bisnis jasa salon. Banyaknya pemutusan hubungan kerja secara sepihak ini telah menyebabkan semakin tingginya jumlah angka pengangguran untuk usia produktif yang seharusnya bekerja pada tahun 2022. Semakin tingginya angka pengangguran bisa mempengaruhi tingkat stabilitas nasional. Dalam upaya untuk mengurangi pengangguran perlu dilakukan penelitian secara khusus mengenai faktor-faktor apa sajakah yang dapat mempengaruhi perkembangan bisnis jasa usaha salon. Tujuan dari penelitian ini adalah untuk mengukur dan menentukan faktor-faktor apa sajakah yang dapat mempengaruhi perkembangan jenis usaha bisnis salon. Penelitian ini menggunakan factor analysis method yang dibantu sebuah aplikasi pendukung dalam proses pengolahan data secara statistika, yaitu software SPSS versi 24. Hasil dari penelitian ini menunjukkan bahwa ada dua jenis faktor yang benar-benar mempengaruhi perkembangan jenis usaha bisnis salon yaitu faktor kebersihan dan faktor kenyamanan. Faktor kebersihan terdiri atas variabel higienis dan variabel sanitasi. Faktor kenyamanan terdiri atas variabel area parkir yang luas, variabel penempatan lokasi yang strategis dan variabel sifat pelayanan yang ramah.

“…In the food industry, cork is mainly used as a cork stopper for wine and spirit bottles. After consumption, although used cork stoppers are recyclable and some initiatives collect, recycle, and generate new products, the largest fraction of cork stoppers is considered waste and is simply discarded [ 12 , 13 ]. In a study reported by Ihamouchen et al [ 14 ], cork waste was combined with polycaprolactone to develop a new cork-based material.…”

The development of sustainable materials from the valorization of waste is a good alternative to reducing the negative environmental impact of plastic packaging. The objectives of this study were to develop and characterize pectin-based composite films incorporated with cork or cork with either coffee grounds or walnut shells, as well as to test the films’ genotoxicity, antioxidant properties, and biodegradation capacity in soil and seawater. The addition of cork, coffee grounds, or walnut shells modified the films’ characteristics. The results showed that those films were thicker (0.487 ± 0.014 mm to 0.572 ± 0.014 mm), more opaque (around 100%), darker (L* = 25.30 ± 0.78 to 33.93 ± 0.84), and had a higher total phenolic content (3.17 ± 0.01 mg GA/g to 4.24 ± 0.02 mg GA/g). On the other hand, the films incorporated only with cork showed higher values of elongation at break (32.24 ± 1.88% to 36.30 ± 3.25%) but lower tensile strength (0.91 ± 0.19 MPa to 1.09 ± 0.08 MPa). All the films presented more heterogeneous and rougher microstructures than the pectin film. This study also revealed that the developed films do not contain DNA-reactive substances and that they are biodegradable in soil and seawater. These positive properties could subsequently make the developed films an interesting eco-friendly food packaging solution that contributes to the valorization of organic waste and by-products, thus promoting the circular economy and reducing the environmental impact of plastic materials.

“…From the point of view of composite construction, CoP stands as the fundamental load-bearing component of the composite, while the polymer matrix acts as the binder, linking and filling cells to distribute external loads efficiently. Moreover, some studies, such as [13], highlight agglomerated cork's amphiphilic properties, enabling easy blending with polymeric elements such as latex, polyethylene or polyurethane for wine stopper production.…”

In the wine bottling process, thermoplastics are commonly used to manufacture the crown of cork stoppers. The production of agglomerated cork stoppers generates a type of waste called cork powder (CoP) in large volumes with known properties but which are still underutilized. At present, although there are many agrocomposites available with additives such as natural fibers or solid residues from agricultural products, there are no studies describing the formation of these agrocomposites from petroleum-derived synthetic plastics combined with cork dust as a reinforcement for the polymeric matrix. The present study describes a novel agrocomposite, which has been obtained by mixing polypropylene-type materials, as they are some of the most widely used and versatile thermoplastics, with cork dust, which is a waste product obtained from the cork industry. The composite is obtained directly, without the need for grafting, adhesive polymers, or coupling agents. A superior mechanical performance compared to the unprocessed polymer was highlighted in the test results, thus evidencing the reinforcing function played by the waste in the polymer matrix. Therefore, this novel agrocomposite could be a promising alternative to replace some petroleum-derived synthetic plastics, which are currently experiencing high demand. The use of this new agrocomposite is well aligned with sustainability strategies, the principles of the circular economy, and oriented towards the fulfilment of the Sustainable Development Goals required by the European Union, considering that it contributes (a) to recycling agricultural waste that would otherwise be difficult to recover and valorize; (b) to the reduction in the CO2 footprint; and (c) to promoting the use of high-quality secondary raw materials.
