Kegiatan pengabdian berupa Iptek bagi Masyarakat (IbM) merupakan salah satu penerapan Tri Dharma Perguruan Tinggi. Dengan adanya kegiatan pengabdian IbM, maka diharapkan akademisi dapat berinteraksi secara langsung dengan masyarakat. Lokasi yang menjadi sasaran kegiatan IbM adalah Desa Penyak Kecamatan Koba Kabupaten Bangka Tengah yang mayoritas mata pencaharian penduduknya adalah sebagai nelayan atau petani. Hasil tangkapan nelayan sebagian diolah menjadi kerupuk kemplang. Masalah yang muncul adalah bahwa proses pengeringan masih menggunakan cara tradisonal yaitu melalui penjemuran secara langsung di bawah terik matahari, sehingga proses pengeringan masih bergantung pada cuaca. Salah satu upaya untuk membantu masyarakat, khususnya kalangan kelompok usaha mikro di bawah naungan Badan Usaha Milik Desa (BUMDes) di Desa Penyak dalam mengatasi permasalahan pengeringan kerupuk kemplang adalah melalui sosialisasi pengeringan kerupuk kemplang menggunakan alat pengering otomatis. Kegiatan sosialisasi akan dilanjutkan dengan transfer teknologi tepat guna dan penyerahan alat pengering otomatis sehingga masyarakat dapat memanfaatkan teknologi tersebut secara langsung untuk meningkatkan kualitas produksi kerupuk kemplang. Hasil evaluasi menunjukkan bahwa kegiatan sosialisasi dan penyerahan alat pengering otomatis dimanfaatkan dengan baik dan bermanfaat bagi masyarakat.

Activated carbon from ketapang shell (Terminalia Catappa) has been successfully synthesized using dehydration-carbonization method. Activated carbon was conducted by immersing with sulphuric acid and followed by carbonization at 600oC for 2 hours. Pore characteristics were determined using imageprocessing methods of activated carbon micrographs based on parameters of area and caliper length. From the area approximation method obtained that the maximum pore size estimate was 5,69 μm at activator concentration 3% while the minimum was 4,88 μm at activator concentration 11% activator concentration respectively. At the other hands, caliper length approximation method obtained estimation of maximum pore size that was equal to 9,09 μm at activator concentration 3% and its minimum that was equal to 7,35 μm at activator concentration 7%. The porosity of the activated carbon from ketapang shell increased with the increase of sulfuric acid concentration and the highest value reached 24.96%.

This study aims to analyze the effect of NaOH concentration on deacetylation step on the chitosan adsorption for Cu metal ions in Bangka tin kolong’s water. Extraction of chitosan was carried out in four steps: deproteinization, demineralization, decolorization and deacetylation of chitin. The effect of NaOH concentration on deacetylation process was studied. The results shown that the increase of NaOH concentration from 20% to 60%, the chitosan DD increased. The diffusion rate of OH- causes increment of OH- attack to the amino group thus realizing the effective deacetylation of chitin. The metal content of Cu in this study reached 0.32 ppm. Adsorption of chitosan on cu metal ions reduced the dissolved levels reaching an average of 99.67% from the initial content. The content of the hydroxyl group in chitosan causes the forming reaction of hydroxide compounds from dissolved Cu metal ions. The Cu hydroxide compound will separately form and form a precipitate. The greater the deacetylation degree value lead increase of hydroxyl group content and causing the increase of Cu metal ions adsorption.

In this paper, the location that is targeted for community service activities is Penyak Village, Koba Sub-District, Central Bangka Regency. The majority of the profession of the Penyak Village community are fishermen because the village is directly adjacent to the South China Sea. Maritime resources in Penyak Village are quite abundant including various types of fish, shellfish and small crab. But most people who market these resources have not used techniques for storing fishery products. Therefore, it is feared that the fishery products will decline in quality. The solution offered to this community service is the socialization of frozen fishery product storage. In addition, in order for the community to directly utilize it, the freezer box equipment was provided to Penyak Village. Through the evaluation process, it is known that the freezer box provided can be utilized by Penyak Village community, especially for storing food products.

Penelitian ini bertujuan menganalisis pengaruh variasi temperatur deproteinasi pada daya adsorbsi kitosan udang krosok (Penaeus semisulcatus) terhadap logam besi (Fe) pada air kolong bekas penambangan timah timah di Pulau Bangka. Bahan baku kitosan yang digunakan dalam penelitian ini merupakan limbah cangkang udang krosok dari industri rumah tangga pembuatan ebi. Kitosan limbah cangkang udang ebi telah disintesis dalam tiga tahapan meliputi: deproteinasi, demineralisasi, dekolorisasi dan deasetilasi. Pada penelitian ini proses sintesis menggunakan variasi temperatur deproteinasi masing-masing: 30oC, 60oC, dan 90oC. Berdasarkan analisis data FTIR, dapat ditentukan nilai derajat deasetilasi sampel berturut-turut sebesar: 32,01% ; 30,94% dan 28,74%. Peningkatan temperatur deproteinasi menyebabkan nilai derajat deasetilasi kitosan menjadi menurun. Penurunan ini diakibatkan oleh rusaknya struktur kitin pada sampel akibat temperatur yang meningkat. Kandungan logam Fe pada air kulong yang digunakan dalam penelitian ini mencapai 6,1 ppm. Adsorbsi kitosan pada logam Fe dapat menurunkan kadar terlarut mencapai rata-rata 99,67% dari kadar awal. Kandungan gugus hidroksil pada kitosan menyebabkan terjadinya reaksi pembentukan senyawa hidroksida turunan dari logam besi terlarut. Senyawa besi hidroksida tersebut akan terpisah dari air dan membentuk endapan. Semakin besar nilai derajat deasetilasi maka akan semakin besar kandungan gugus hidroksil sehingga menyebabkan daya adsorbsi kitosan semakin meningkat.

Meskipun ilmu fisika merupakan salah satu ilmu yang sangat penting dalam pengembangan teknologi saat ini namun di mata mayoritas peserta didik masih dianggap sebagai ilmu yang sulit dan tidak menarik. Hal ini kemungkinan disebabkan oleh masih banyaknya guru yang hanya menerapkan metode ceramah ketika proses belajar mengajar fisika. Alternatif untuk mengatasi permasalahan tersebut adalah diterapkannya praktikum agar peserta didik dapat memiliki pengalaman langsung terkait konsep fisika yang ada. Namun, beberapa sekolah di Bangka tidak memiliki fasilitas laboratorium yang memadai sehingga kegiatan praktikum tidak dapat berjalan dengan baik atau bahkan tidak dapat dilaksanakan. Pada program pengabdian kepada masyarakat ini, dilakukan pelatihan penggunaan perangkat lunak PhET sebagai solusi laboratorium virtual. Penggunaan laboratorium virtual selain efisien dari segi biaya juga mudah untuk dilakukan dan memungkinkan peserta didik melakukan praktikum virtual secara mandiri. Setelah dilakukan kegiatan pelatihan mayoritas peserta memberikan respon positif terhadap penggunaan PhET dalam proses belajar mengajar. Selain itu, perangkat lunak PhET mudah digunakan.

In this research, the synthesis and characterization of chitosan modified carbon composites based on biomass carbon has been carried out using the microwave method. Chemically activated carbon with 2.5% H3PO4 activator was stirred using a magnetic stirrer for 1 hour and allowed to stand for 24 hours. The carbon was then physically reactivated using a microwave for 20 minutes with a power variation of 800, 1000 and 1200 watts and a Scanning Electron Microscopy (SEM) test was carried out. After the SEM test, chitosan modified carbon was synthesized with a composition ratio of 1:1, 2:1 and 3:1 and the specific capacitance was measured using Galvanostatic Charge-Discharge (GCD) testing. The SEM test results analyzed using ImageJ software-based image processing methods show that the value of sphericity, pore size and carbon porosity decreases with increasing microwave power used. The optimum conditions based on the value of Sphericity, pore size and porosity were obtained at a variation of 800 watts of microwave power with values of 0.952, 0.832 m, and 25.87%, respectively, which were included in the macropore size (>50 nm). Because the higher the power used, the smaller the pore area and porosity. The electrode-specific capacitance values were 3.4 x 10-1 F/g, 24.02 F/g, and 1.3 x 10-1 F/g, respectively. Electrodes with a ratio of 2:1 have the largest capacitance value, because they can be charged by an electric charge. The longer the charge-discharge process, the greater the capacitance value, so the curve will approach a more symmetrical isosceles triangle shape.
