Abstract

Plasma technology has interested, especially plasma in liquid which can be applied in the process of gas productions, water treatment, and nanomaterial productions. The purpose of this study is to make a simple technology 2.45 GHz microwave plasma and generate in the variation of liquids such as distilled water, seawater, and X-Ray liquid waste by utilizing a microwave oven, as well as to observe the effect of vacuum pressure variations. A microwave oven was modified by integrating a waveguide and a plasma reactor for plasma observation. The results, plasma was generated in distilled water at a vacuum pressure of about 7 kPa, X-Ray liquid waste at a vacuum pressure of about 13 kPa, and seawater at a vacuum pressure of about 34 kPa.

Abstract

Sugarcane (Saccharum officinarum L.) is a raw material that is processed to produce crystal sugar and bioethanol. The process produces sugarcane bagasse. In this study, The liquid-plasma treatment based on microwave plasma in the liquid was used to treat sugarcane bagasse to observe the effect on glucose concentration and gain byproducts. The energy input parameters were varied by 340, 360, and 400 W with irradiation time variations of 1, 3, and 5 minutes. Nelson Somogyi's method was used to determine the percentage of glucose as well as Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscope (SEM), and Image-J software to characterize the side-product of the samples. The results showed that the glucose concentration reduced around 27.6% - 99.2 % after microwave plasma in-liquid treatment at the energy input of 340 Watt and 360 Watt, respectively, with an irradiation time of 5 minutes. The side-product is cellulose nanoparticles which have an average diameter of 92, 106, and 169 nm

Abstract

Teknologi pembangkitkan plasma dalam cairan dengan memanfaatkan gelombang elektromagnetik 2.45 GHz oven microwave telah dilakukan sebelumnya. Tujuan penelitian ini adalah untuk menganalisis pembangkitan microwave plasma dalam berbagai sampel cairan seperti cairan rontgen, pure water, air baku PDAM dan air laut. Hasil penelitian menunjukkan bahwa pembangkitan plasma dalam berbagai sampel cairan membutuhkan waktu awal pembangkitan sekitar 1-2 detik pada tekanan 6.7 kPa. Karakteristik warna plasma yang dihasilkan dalam cairan rontgen dan air laut adalah sama yakni orange, dan karakteristik warna plasma yang dihasilkan dalam pure water dan air baku PDAM adalah sama yakni pink.

Abstract

Kota Tarakan merupakan kota dengan pertumbuhan penduduk yang cukup tinggi di Provinsi Kalimantan Utara. oleh karena itu, kegiatan pembangunan juga meningkat dan kualitas lingkungan akan menurun akibat pencemaran limbah seperti limbah plastik rumah tangga. Tujuan penelitian ini adalah merancang bangun mesin pencacah limbah plastik yang diintegrasikan dengan sistem rotation control untuk tiga jenis sampah plastik yakni Polypropylene, Polyethylene Terephthalate, dan High-Density Polyethylene. Hasil penelitian ini menunjukkan bahwa mesin pencacah plastik yang telah dibangun terdiri dari frame mesin yang dibuat dari bahan besi siku dengan dimensi 40 x 40 x 3 mm, pisau pencacah bermata 2 dan cover yang terbuat dari bahan ST37, hopper dari bahan plat besi tebal 1,2 mm, motor listrik 1 HP, sistem transmisi puli dengan perbandingan 1:4 dan gearbox dengan perbandingan 1;15, dan sistem rotation control. Kapasitas mesin yang dihasilkan untuk ketiga jenis sampah plastik sebesar 7,2; 7,14; dan 6,6 kg/jam, masing-masing.

Abstract

The coastal area of Pantai Amal, Tarakan City, Indonesia, faces two major environmental challenges: the accumulation of post-harvest seaweed biomass waste and increasing coastal abrasion caused by climate change, both of which threaten environmental quality and the sustainability of local livelihoods. This Community Service Program aimed to develop an integrated community empowerment model by combining appropriate technology, mangrove rehabilitation, and institutional strengthening to address seaweed waste management and climate change adaptation. The program employed a Participatory Action Research (PAR) approach through four iterative stages: Plan, Act, Observe, and Reflect, actively involving community members in planning, implementation, evaluation, and program improvement. The results demonstrated the successful installation of two appropriate technology units, namely a portable solar dryer and a biomass chopper, followed by technical training for 30 community participants, all of whom were able to operate the equipment independently after the training. In addition, 1,000 Rhizophora mangrove seedlings were planted in erosion-prone coastal areas, while a tourism website and official social media platforms managed by the local Tourism Awareness Group (Pokdarwis) were established to strengthen digital promotion and community participation. The novelty of this program lies in the integration of circular economy-based seaweed waste management, ecosystem-based mangrove rehabilitation, and community institutional empowerment into a single community service model. This integrated approach contributes to strengthening local capacity in sustainable resource management, enhancing coastal resilience, and supporting the development of Pantai Amal as a sustainable community-based tourism destination.
