Subang Regency is designated as a pineapple commodity area due to the presence of natural resources, supporting facilities, and infrastructure. Pineapple harvest waste in the form of pineapple leaves is used by a local SME, Alfiber, as textile raw materials, such as yarn and cloth. However, there are still short fibre residues that cannot be utilized in the process. Through training activities for Alfiber members and the people of Cijambe Sub-district, Subang District, West Java, the ITB community service team provided an alternative solution for utilizing the short fibres of pineapple leaves by processing them into paper. This community service activity uses a qualitative approach consisting of four stages: the initial stage, preparation, activities, and results. The initial stage is preliminary research. The preparation stage and activities are participatory and educative and involve the ITB community service team, Alfiber, and the people of the Cijambe Sub-district. The results of the training activities prove that short fibres can be processed into paper using simple equipment and paper-making techniques such as moulding techniques. After participating in the activity, the participants succeeded in following the activity material and could make pineapple fibre paper independently. Even though it requires improvement in terms of quality, the paper can be produced into other products using paper as the primary material. [ABSTRACT FROM AUTHOR]

ABSTRAK Tujuan dari penelitian ini adalah untuk mengetahui sifat fisis dari kertas yang dihasilkan. Metode penelitian yang digunakan adalah metode eksperimen dengan tujuan untuk mencari alternatif bahan baku kertas. Terdapat variasi persentase berat dalam campuran antara daun nanas dan kulit durian, yaitu 40%:60%, 50%:50%, dan 60%:40%. Daun nanas dan kulit durian dimasak dalam larutan NaOH 3% pada suhu 90℃, kemudian dilakukan proses pemutihan dengan larutan H2O2 10% lalu disaring dan dikeringkan. Setelah kering, pulp dicampur dengan komposisi yang telah dirancang menggunakan blender dan dicetak menggunakan cetakan kertas. Hasil pengujian sifat fisis kertas menunjukkan nilai gramatur tertinggi yaitu 90 gram/m2 yaitu pada variasi sampel 40%:60% dan nilai terendah yaitu 79 gram/m2 pada variasi sampel 60%:40%. Untuk pengujian bulk nilai tertinggi yaitu 1,44 cm3/gram pada variasi sampel 60%:40% dan nilai terendah yaitu 1,22 cm3/gram pada variasi sampel 40%:60%. Dari nilai tersebut sudah memenuhi nilai SNI 7274:2008 untuk menjadi mutu kertas cetak A. Kata kunci: kertas, selulosa, daun nanas, kulit durian. ABSTRACT The purpose of this research is to determine the physical properties of the paper produced. The research method used is an experimental method with the aim of finding alternative raw materials for paper. There are variations in the percentage of weight in the mixture between pineapple leaves and durian skin, namely 40%:60%, 50%:50%, and 60%:40%. Pineapple leaves and durian skin are cooked in 3% NaOH solution at 90℃, then a bleaching process is carried out with 10% H2O2 solution and then filtered and dried. After drying, the pulp is mixed with the composition that has been designed using a blender and printed using a paper mold. The results of testing the physical properties of the paper showed that the highest grammage value was 90 gram/m2 at the sample variation of 40%:60% and the lowest value was 79 gram/m2 at the sample variation of 60%:40%. For bulk testing, the highest value is 1,44 cm3/gram for a sample variation of 60%:40% and the lowest value is 1,22 cm3/gram for a sample variation of 40%:60%. From this value, it meets the value of SNI 7274: 2008 to become A printing paper. Keywords: paper, celluloce, pineapple leaves, durian skin.

Introduction. Social restrictions due to COVID-19 have made it difficult to obtain research data and literature to support publication activities. Universitas Airlangga (UNAIR) provides Remotex facilities or remote repository access, where academics can read and download journals of international repute. This paper aims to analyze whether there is a relationship between RemoteXs access by faculty and the number of publications on Scopus. Methodology. This study uses statistical data on the number of times the repository is accessed by the faculty. a sample of the number of papers was also taken from the Scopus website. Data were analyzed by the Pearson Correlation method. Results and discussion. The results of the study show that the number of lecturers' accesses has no correlation with the number of publications. Meanwhile, the total repository access at the faculty is strongly correlated with the number of publications. Conclusion. There is no relationship to how many times the number of RemoteXs access publications on Scopus. However, there is a relationship with the faculty, this is because of the doctoral program in the faculty that is required for publication.
