Abstract

Sampah secara umum dihasilkan dari kegiatan manusia sehari-hari. Dari berbagai jenis sampah, sampah plastik merupakan sampah non-organik yang paling banyak dihasilkan, tidak dapat diurai secara alamiah, dan memiliki dampak bagi kesehatan maupun lingkungan. Kabupaten Lombok Timur, memproduksi sampah terbanyak setiap harinya di Provinsi Nusa Tenggara Barat. Usaha mengurangi sampah perlu didukung oleh kesadaran masyarakat untuk mengurangi sampah dan memilah sampah sehingga dapat mengurangi beban pengelolaan sampah yang dilakukan oleh pemerintah daerah, terlebih setelah pemerintah propinsi NTB menggaungkan program Net Zerowaste Emission Tahun 2050. SMA N 2 Selong merupakan salah satu sekolah di wilayah Selong Lombok Timur yang diharapkan mampu menjadi pionir dalam edukasi pengembangan kesadaran diri sehingga memiliki peran yang sangat stategis untuk mengedukasi masyarakat. Oleh karena itu, untuk mengatasi permasalahan sampah perlu dilakukan edukasi pemilahan sampah plastik di lingkungan sekolah. Bahkan perlu diperkenalkan manfaat mendaur ulang sampah karena hal ini akan menunjukkan animo generasi muda dalam mewujudkan program zero waste di lingkungan SMA N 2 Selong, dan nantinya diharapkan pada generasi muda di seluruh wilayah Lombok Timur. Kegiatan ini diikuti oleh siswa kelas X, XI dan XII sejumlah 54 siswa terpilih dan hampie seluruh guru SMA N 2 Selong dengan respon Sangat Memuaskan.

Abstract

The increase in energy needs must be balanced by environmentally friendly technological innovations. Chitosan polymer is one of the technological innovations of energy materials that are being developed by many developed countries. This research aimed to identify the potential of oyster pearl shell waste as a source of electrolyte polymers. The study was conducted experimentally by synthesizing chitosan nanoparticles from chitosan using the ionic gelation method. Chitosan is obtained through the isolation method from Pinctada maxima oyster pearl shell waste. The isolation method is carried out by three processes: deproteination, demineralization, and deacetylation. Several characterizations were carried out to analyze the material from the synthesis, including a proximate test, FTIR analysis, and PSA analysis. Isolated chitosan was identified to have a deacetylation degree that reached 88.63% with the formation of OH and NH2 functional groups. In general, the proximate tets data has shown that the obtained chitosan already meets the Indonesian standard SNI 7949:2013. PSA analysis resulted in differences in size distribution, PDI, and zeta potential between chitosan and chitosan nanoparticles. The results were obtained by the average distribution of chitosan particle size of 52.043 μm and chitosan nanoparticle size of 2.3365 μm—the analysis of the potential zeta of chitosan -3.9 mV and chitosan nanoparticle -21,6 mV. Thus, changes in the size of the chitosan material affect its potential PDI and zeta values. The change of these two values is a good indicator of the initial data and the potential of the material as an energy material. Therefore, chitosan polymer is an electrolyte material that can be used as a candidate for environmentally friendly renewable energy materials

Abstract

Melanjutkan studi ke perguruan tinggi merupakan impian banyak tamatan SMA sederajat. Untuk mewujudkannya, calon mahasiswa harus mempersiapkan diri dengan belajar dan bekerja keras, terutama bagi mereka yang tidak lolos jalur SNBP (Seleksi Nasional Berdasarkan Prestasi) dan harus menghadapi tes UTBK (Ujian Tulis Berbasis Komputer). Program pengabdian ini bertujuan memberikan pengalaman kepada siswa kelas XII tentang bentuk dan tingkat kesulitan tes masuk Perguruan Tinggi Negeri (PTN) serta cara penyelesaiannya. Pengalaman ini membantu siswa mengukur kesiapan mereka dalam menghadapi UTBK sekaligus memotivasi mereka meningkatkan waktu, kualitas, dan kuantitas belajar. Pelaksanaan program terdiri atas tiga tahapan: persiapan, pelaksanaan, dan evaluasi. Kegiatan utama meliputi: (1) review konsep matematika dasar, (2) ujicoba tes pengetahuan kuantitatif dan penalaran matematika, serta (3) pembimbingan soal ujicoba oleh tim. Hasil ujicoba menunjukkan kemampuan siswa dalam pengetahuan kuantitatif dan penalaran matematik masih rendah. Namun, pembimbingan terstruktur meningkatkan pemahaman siswa, menyadarkan mereka akan banyaknya materi yang perlu dipelajari, dan mendorong semangat belajar. Program ini juga membantu siswa lebih memahami jurusan yang diminati. Direkomendasikan kepada pihak sekolah untuk memberikan pembinaan intensif kepada seluruh siswa guna meningkatkan peluang lulus seleksi masuk PTN.

Abstract

The purpose of this study was to find out how students perceive online learning during this pandemic. This study uses a qualitative descriptive method consisting of data collection, data reduction, data presentation and drawing conclusions. The subjects of this study were active Pharmacy students of STIKes Salsabila Serang from semesters 2, 4, 6 and 8, totaling 376 respondents. The data in this study were obtained using a questionnaire instrument distributed through Google Form with a Likert scale from 1 to 5: 1 means strongly disagree and 5 means strongly agree. There are three aspects of questions in the questionnaire distributed, these aspects are 1) aspects of teaching and learning, 2) aspects of lecturer competence, and 3) aspects of facilities and infrastructure. Of the three aspects, aspect 1 is in the Medium category with an average perception value of 3.40, aspect 2 is in the high category with an average perception of 3.94, and aspect 3 is in the high category with an average perception of 3.85. Furthermore, from the results of the recapitulation of the percentage of respondents' answers as a whole, it can be concluded that in general, Pharmacy students at STIKes Salsabila Serang have high perception of online learning with a perception average value of 3.72.   Tujuan penelitian ini adalah untuk mengetahui bagaimana persepsi mahasiswa terhadap pembelajaran secara daring di masa pandemi ini.

Abstract

Blood clam shells are inorganic materials rich in  content obtained from heating  at high temperatures, so they can be used as adsorbent. The purpose of this study is to determine the effect of calcination temperature of blood clam shell adsorbents, used to test the quality of used cooking oil (wosting oil). In this study, three calcination temperature variations were used, namely 800 ℃, 900 ℃ and 1000 ℃ for 2 hours each. Then the quality of adsorbent was tested by knowing oxide element with SEM. The adsorption process was carried out using the contact method by immersing the adsorbent in wosting oil for one hour. Wosting oil that has been adsorbed is then tested for quality, namely: free fatty acid content, peroxide number, water content, viscosity, density, physical properties (odor and color). The results obtained are: The best quality of  adsorbent was obtained at a calcination temperature of 1000 ℃ which was analyzed through three parameters namely,  content, density value and surface area. The best quality of wosting oil is obtained in used cooking oil with 3 times heating with calcined adsorbent at 1000 ℃ which is analyzed based on several parameters as previously explained.
