Abstract

Modified chitosan membrane is one of the promising membranes for polymer electrolyte membrane. Chitosan/N-phthaloyl chitosan composite membranes were fabricated to obtain high proton conductivity and low methanol permeability. Membranes were fabricated by casting method and solvent evaporation. Surface morphology, mechanical analysis, methanol permeability, and proton conductivity were used to characterize the overall properties. FT-IR spectra exhibited the presence of interaction of chitosan and n-phthaloyl/chitosan. SEM analysis showed that the surface roughness of composite membrane increases as the n-phthaloyl loading increases. The highest proton conductivity of synthesized membrane is at 2.4 mS.cm-1 and is higher than pristine chitosan membrane at 1.6 mS.cm-1. Moreover, with n-phthaloyl/chitosan addition, the methanol permeability was also improved. The correlation between proton conductivity and methanol permeability in composite membranes suggests that the blend has its potential in DMFC application.

Abstract

Ketersediaan laboratorium kimia di SMA sangat diperlukan untuk meningkatkan kualitas pembelajaran melalui metode praktikum. Kecukupan jumlah guru dan laboran juga sangat mempengaruhi kelancaran pelaksanaan praktikum. SMA Negeri 5 Balikpapan merupakan salah satu SMA ternama yang memiliki alat dan bahan praktikum kimia cukup memadai, namun sempat mengalami kekosongan kegiatan praktikum. Tim dosen dan mahasiswa Prodi Teknik Kimia Institut Teknologi Kalimantan (ITK) melakukan identifikasi untuk mengetahui alat dan bahan yang dapat digunakan. Hasil identifikasi menunjukkan bahwa alat dan bahan yang ada memadai untuk berbagai materi praktikum kimia, termasuk praktikum titrasi asam basa, yang termasuk materi sulit dalam ilmu kimia. Modul praktikum disiapkan untuk menjadi acuan bagi siswa. Pre-test dan post-test digunakan untuk mengetahui dampak pelaksanaan praktikum titrasi. Praktikum titrasi menunjukkan dampak yang signifikan dalam mengoptimalkan pemanfaatan laboratorium kimia dan meningkatkan pemahaman siswa terhadap titrasi asam basa.

Abstract

One way to reduce the scarcity of fuel oil is to make environmentally friendly alternative fuels such as biodiesel. The utilization of biodiesel can be a new energy source and also help reduce the excessive use of fuel, especially diesel and diesel oil in Indonesia. In Indonesia, the amount of palm oil will reach 49.7 tons by 2021, and this data is up 2.9% from the pre-vious year. Palm fruit is processed into CPO. More palm oil processing will produce waste called POME (Palm Oil Mill Effluent). The diesel engine transesterification method is suitable for the manufacture of biodiesel. The amount of base on the catalyst's surface affects the catalyst's activity. So that the higher the base value on the catalyst, the higher the yield of biodiesel that will be produced. The biodiesel produced will be tested on a 4-stroke diesel engine with a B5 and B10 blending composition. The study's results showed that the density and viscosity values for B5 were 5.8 cSt and 810 Kg/m3 and for B10 were 6.3 cSt and 860 Kg/m3. As for engine performance, power, torque, and SFC for B5 fuel at 4000-watt load conditions and 1000 Rpm, engine speeds are 1.18 Kw, 11.28 Nm, and 256.8 gr/Kw. B10 at 4000-watt load condition and 1000 Rpm engine speed is 1.16 Kw, 11.12 Nm, and 269.2 gr/Kw.

Abstract

The process of processing batik liquid waste using membrane technology has been implemented to overcome the problem of batik waste in the Sekar Buen Batik IKM Area through a community service program. The method used is the batik liquid waste filtration technique using a membrane. This community service activity is an effort to help strengthen the human resources of the batik industry community in the liquid waste processing process at the Sekar Buen Batik IKM located in North Penajam Paser. The activity has been carried out in several stages, including a preliminary survey, a discussion forum on batik waste problems with a partner team, making a design for a waste processing system based on membrane technology and working practices for the tool. This program can help partners in processing batik wastewater so that it can reduce its negative impact on the environment. The results of the program show that partners have an understanding of the technique of processing batik liquid waste based on membrane technology. Thus, industrial activities at the Sekar Buen Batik IKM can support the green industry area and be more environmentally friendly.

Abstract

Abstrak: Teknologi membran menjadi solusi yang efisien dan ramah lingkungan, sehingga berpotensi dikembangkan sebagai sistem pengolahan air minum kaya oksigen (AMIKO) di Pondok Pesantren. Mitra pada program ini adalah Pondok Pesantren Syaichona Cholil Balikpapan yang memiliki 554 santri yang tersebar pada berbagai jenjang pendidikan formal, diantaranya Taman Kanak-Kanak (TK), Madrasah Ibtidayah (MI), Sekolah Menengah Pertama (SMP), Sekolah Menengah Atas (SMA), Sekolah Menengah Kejuruan (SMK) dan Sekolah Tinggi Ilmu Tarbiyah (STIT). Program ini bertujuan untuk memenuhi kebutuhan air minum berkualitas bagi santri dan ustadz/ustadzah, mendukung kesehatan, dan kelancaran kegiatan belajar mengajar. Sistem ini, selain dapat memenuhi kebutuhan air minum yang sehat, juga dapat menjadi peluang unit usaha mandiri yang dikelola oleh pesantren. Dengan demikian, program ini tidak hanya meningkatkan kesehatan para santri tetapi juga memberikan keterampilan dan kemandirian dalam pengelolaan air minum. Metode yang digunakan pada program ini adalah sosialisasi pentingnya air minum sehat dan pelatihan teknis penggunaan alat sistem pengolahan air minum berbasis teknologi membran. Kegiatan sosialisasi telah dilakukan kepada para santri dan ustadz/ustadzah berkaitan dengan pentingnya air minum yang berkualitas beserta karakteristiknya dan penjelasan tentang sistem pengolahan air minum berbasis teknologi membran. Evaluasi yang digunakan untuk mengetahui perkembangan mitra adalah dengan melalui pembagian kuesioner.

Abstract

Abstrak: Pengolahan limbah minyak jelantah merupakan salah satu metode yang digunakan sebagai upaya mengurangi jumlah buangan sampah organik. Limbah minyak jelantah yang langsung dibuang melalui sink dan berakhir ke badan air di selokan akan mengakibatkan banyak dampak negatif baik bagi masyarakat ataupun lingkungan. Pengolahan limbah minyak jelantah menjadi sabun memiliki dampak langsung dalam mengurangi volume sampah organik sekaligus bertujuan untuk meningkatkan keterampilan warga. Hal ini dapat mendorong pengembangan ekonomi kreatif secara berkelanjutan bagi masyarakat. Kegiatan pengabdian dihadiri oleh seluruh anggota PKK RT.40, Gunung Samarinda, Kota Balikpapan, dengan jumlah peserta sekitar ± 25 orang. Selama kegiatan, metode yang diterapkan adalah praktik langsung yang dilanjutkan dengan evaluasi dan monitoring pasca pelatihan bersama warga. Kuesioner digunakan sebagai alat evaluasi untuk mengukur peningkatan keberhasilan kegiatan yang dilakukan. Berdasarkan hasil kuesioner, terjadi peningkatan pemahaman serta keterampilan warga sebesar 30%. Selain itu 80% warga menyatakan bahwa proses pembuatan sabun dari minyak jelantah sangat menarik, mudah dipraktikkan dan bahan-bahannya mudah didapatkan dipasaran. Abstract: The processing of used cooking oil waste is one of the following methods used as an effort to reduce the amount of organic waste disposal. Direct disposal of used cooking oil waste through sinks and into water bodies or sewers can have significant negative impacts on both the community and the environment. Processing used cooking oil waste into soap has a direct impact on reducing the volume of organic waste as well as improving the skills of the community. The process aims to enhance the skills of the residents. This can encourage the development of a sustainable creative economy for the community. All members of PKK RT.40, Gunung Samarinda, Balikpapan City, attended the community service activity, with a total of approximately 25 participants. The activity employed a hands-on practice method, followed by a post-training evaluation and community monitoring. We used questionnaires as an evaluation tool to gauge the success of the activities we carried out. The questionnaire showed a 30% increase in community understanding and skills. In addition, 80% residents stated that the process of making soap from used cooking oil is very interesting, easy to practice and the ingredients are easily available in the market.
