Abstract

Teknologi pemisahan gas telah banyak dilakukan menggunakan membran. Mixed matrix membran (MMMs) telah banyak dikembangkan dengan mengkombinasikan polimer organik dan filler anorganik. Pemisahan gas dengan mixed matrix membrane telah banyak dikembangkan dan menghasilkan kinerja yang sangat baik. Pada pemisahan gas CO 2 /CH 4, satu hal yang diutamakan dan diperhatikan adalah permeabilitas yang tinggi. Umumnya semakin tinggi permeabilitas suatu gas dalam membran, maka semakin rendah pula selektivitasnya dan begitu pula sebaliknya. Beberapa filler yang baik digunakan untuk mixed matrix membrane yaitu dengan filler material silika, nanopartikel NiO, grafena oksida dan metal organic frameworks (MOF).Kata Kunci: Mixed matrix membrane, pemisahan gas

Abstract

Kelurahan Kalampangan memiliki luas wilayah 5000 hektare dengan jumlah penduduk mencapai 4000 jiwa. Sebagian besar mata pencaharian utama penduduk adalah bertani. Kelompok tani lokal dibentuk pemerintah untuk dapat secara mandiri meningkatkan kesejahteraan ekonomi. Kelompok ini secara rutin telah mendapatkan pelatihan mengenai pembudidayaan sayuran dan tanaman berkhasiat obat. Namun hingga saat ini, hasil budidaya hanya dijual dalam kondisi segar yang tentunya memiliki berbagai kelemahan diantaranya daya simpan yang pendek karena mudah sekali membusuk dan rusak serta memiliki harga jual yang rendah. Oleh karena itu pelatihan untuk meningkatkan keterampilan pengolahan pasca panen sangat diperlukan. Pelatihan ini bertujuan agar peserta dapat menghasilkan produk minuman instan yang bernilai jual tinggi. Metode yang digunakan adalah pelatihan langsung kepada 30 peserta (terdiri dari masyarakat, anggota PKK dan perangkat desa). Pemberi pelatihan terdiri dari dosen dan mahasiswa. Pelatihan yang diberikan meliputi pengolahan simplisia, pembuatan minuman, pengemasan dan edukasi tentang ciri produk yang baik serta berkualitas. Pada pelatihan masyarakat dikenalkan dengan metode kristalisasi yang dapat menghasilkan produk bercita rasa enak dan tahan lama jika disimpan. Pelatihan dilaksanakan di Aula Kantor Kelurahan Kalampangan pada hari Kamis tanggal 29 September 2022. Kuesioner sesudah pelatihan untuk menilai tingkat pemahaman para peserta mengenai keterampilan dalam mengolah tanaman obat menjadi produk instan. Hasil kuesioner menunjukkan tingkat pemahaman peserta dalam kategori baik sekali (87,2%).Kalampangan has an area of 5000 Ha with a population of 4000 people. Most of the people's main livelihood is farming. The government formed local farmer groups to improve economic welfare independently. This group has routinely received training on cultivating vegetables and medicinal plants. However, cultivated products are only sold in fresh condition, which has various weaknesses, including a short shelf life because it is easy to rot and damage and has a low selling price. Therefore, training to improve post-harvest processing skills is needed. This training aims to enable participants to produce instant beverage products with high selling value. The method used is direct training to 30 participants (consisting of the community, PKK members and village officials). The training providers consist of lecturers and students. The training provided includes simplicia processing, beverage manufacture, packaging and education about the characteristics of good and quality products. In training, the community was introduced to the crystallization method, which can produce a product that tastes good and lasts a long time if stored. The training was held in the Kalampangan Village Office Hall on Thursday, September 29, 2022. A questionnaire after the training was conducted to assess the participants' level of understanding regarding skills in processing medicinal plants into instant products. The questionnaire results showed the level of understanding of the participants in the very good category (87.2%).

Abstract

As an effort by the Ministry of Education and Culture to improve the quality of human resources, an independent learning policy was made. The quality of Indonesian human resources is still a challenge to solve because the results of surveys from international institutions such as PISA (Program for International Student Assessment) and TIMSS (Trend in International Mathematics and Science Study) still show a protruding ranking. In independent learning there are four main policies, namely (1) freedom of student assessment, (2) national exams replaced by AKM (Minimum Competency Assessment) and character surveys, (3) RPP (Learning Implementation Plan) one sheet, and (4) PPDB system (New Student Admissions) zoning. Therefore, to increase the success of implementing independent learning, it is necessary to have the ability of teachers in the teaching process which results in an independent student learning process. This article uses the literature review method to assess the teacher's abilities. The data collection method uses analysis of data sources obtained from various forms such as journal articles, books, Ministry of Education and Culture policies, and statutory documents. The results of this study indicate that to implement independent learning teachers must master pedagogical skills, skills to adapt teaching styles to student learning styles, skills to master online learning, and skills to master learning strategies. In addition, teachers must also master the principles of independent learning, forms of independent learning, and student learning activities.
