Abstract

Pencemaran udara memberikan dampak terhadap meningkatnya kejadian penyakit yang berkaitan dengan pernafasan. Penyebab utama pencemaran udara tersebut adalah gas buang aktifitas transportasi umum dan pribadi, indikator pencemaran udara harus lebih diperhitungkan walaupun jumlahnya kecil. Adanya konsentrasi polutan yang terlalu banyak di dalam ruangan juga dapat menimbulkan gangguan pernapasan dan permasalahan kesehatan lainnya. Tujuan dari penelitian ini adalah untuk mendesain mesin portable hepafis plasma penjernih udara menggunakan UVC dan mengetahui pengaruh sinar UVC terhadap kualitas udara pada ruangan. Metode pelaksanaan yang dipakai dalam penelitian ini yaitu perancangan alat penjernih udara menggunakan UVC 8W-JP-T5-UV dengan cara menguji udara hasil filtrasi yang masuk ke dalam mesin jumlah kadar polutan dan nilai bakteri yang disesuaikan dengan indeks kualitas udara.  Data dari hasil pengujian alat penjernih udara menggunakan UVC diranacang memakai mikrokontroler berupa arduino uno untuk mengolah hasil pembacaan sensor dan mengirim data. Sensor yang digunakan yaitu MQ-135 untuk membaca kualitas udara, pembacaan ditampilkan pada LCD nilai polutan kualitas udara. Hasil dari pengujian polutan kualitas udara diketahui untuk udara ruangan normal dari 100 ppm ke 46 ppm dan udara ruangan berasap dari 334 ppm ke 46 ppm dimana udara ruangan tersebut baik untuk manusia sesuai dengan Indeks Standar Pencemaran Udara. Selanjutnya untuk nilai angka bakteri hasil pengecekan laboratorium dari hasil pengujian selama 30 sampai 120 menit maka hasil uji angka bakteri sudah memenuhi batas baku mutu yaitu dibawah 500 cfu/m3 hasil pengujian 188 sampai 44 cfu/m3 sehingga mesin uji hepafis plasma menggunakan UVC berpengaruh terhadap pengurangan angka bakteri.

Abstract

In processing potatoes into sticks on a large scale, an equipment is needed that can facilitate the manufacturing process. Therefore, it is necessary to research the design of the potato peeler and cutter and test the performance of the tool. This study aims to determine the design and selection of materials, to determine the production process of potato peeler and cutter and to determine the effect of rotation on time and level of cleanliness of potatoes. This machine consists of several components, namely the frame, peeler tube, cutting tube, transmission unit and electric motor. The working mechanism of this tool is that the peeler disc which is moved by an electric motor rotates to push the potatoes, so that the rotation causes friction between the potatoes and the peeler tube which has a rough surface, this friction causes the potato skin to peel off and is then forwarded to the potato cutter tube with a propeller, which is driven by an electric motor so that the rotation pushes the potatoes into the knife so that the potatoes that pass through the peeler tube are cut into sticks. From the results of testing the tool obtained data on potatoes grade A with an average time of 2 minutes and a motor rotation of 170 rpm, capable of peeling 96.8% of potatoes with a weight loss of 3.2% of potatoes. For potatoes grade B with an average time of 2 minutes and a motor rotation of 170 rpm was capable of peeling 97% of potatoes with a weight loss of 3%, and the results of potato cuts with a cross sectional size of 6.9 × 6.9 mm.Keywords:   french fries, peeler, cutter, potato stick

Abstract

Sumber energi listrik sangat dibutuhkan untuk memenuhi target elektrifikasi yang merata di pedesaan. Pemenuhah energi listrik di pedesaan tersebut dapat menggunakan energi setempat yang tersedia misalkan energi air. Potensi energi air yang dapat dimanfaatkan dapat berasal dari sungai-sungai kecil dengan pembangkit mini dan mikro-hidro. Tantangan terbesar dalam pemanfaatan energi air pada sungai-sungai tersebut adalah bagaimana mendesain turbin air yang sesuai dengan tipe sungai low head tersebut. Karena setiap lokasi air memiliki kondisi lokasi yang berbeda, maka desain, pemilihan jenis dan ukuran turbin yang tepat menjadi lebih penting. Penelitian ini merupakan desain secara teoritis dalam optimasi perancangan profile sudu turbin serta analisis efek pusaran air pada prestasi turbin. Metode yang digunakan dalam penelitian ini adalah dengan mengembangakan model turbin menggunakan teori sayap. Selanjutnya dengan analisis numerik dihitung analisis daya hilang pada sistem akibat pusaran air. Hasil simulasi menunjutkan bahwa sudut serang optimum menghasilkan daya prediksi sebesar 976 W, serta daya hilang pada pusaran sebesar 8 W, sementara daya hilang total sebesar 59.5W atau efisiensi sistem berkurang 6% dengan efisiensi keseluruhan sebesar 74.5%.

Abstract

This study aims to explore the potential for biomass-based power plant to accelerate the development of renewable energy to replace the role of fossil energy in Merauke district, South Papua Province. The method used in this study is, first, to collect data and analyze the load on the grid system and the portion of the energy mix as well as the availability of woody biomass from forest areas by making a simulation of the development of a 2 x 12 MW Biomass Power Plant. Second, by conducting experiments to obtain woodchip conversion, as the fuel of the Biomass Power Plant, from the wood log and conversion from Biomass Power Plant capacity to the required biomass plantation area. The results provide an overview of the big potency for developing biomass-based power generation by utilizing biomass from the local industrial plantation forest and show the energy transition towards energy independence. This study can be useful for policy makers and opportunities for entrepreneurs or suppliers of wood biomass, as well. For the future, in terms of fuel efficiency, it is necessary to reduce the plantation area as a source of biomass for power plants by reducing the moisture content of the woodchip to increase the calorific value and utilizing the forest residue. Furthermore, the comparison cost study between fossil power plant and biomass power plant, as well as the strategy for preserving the plantation to ensure a steady biomass supply is conducted.

Abstract

This Community Partnership Program (PKM) was implemented to support the empowerment of a group of lobster farmers in Sawarna Village, who face various challenges in managing their farming business. The problems faced by lobster farmer groups in the village are lack of access to stable energy and limited management knowledge, which has an impact on the sustainability of the lobster farming business. The purpose of this service is to improve the knowledge and skills of lobster farmers in business management and adopt renewable energy technology as a solution to limited energy access. The method used in this activity is the Participatory Rural Appraisal approach, which involves farmers actively through socialisation, training, technology application, mentoring, and continuous program evaluation. The results of this service showed an increase in the ability of partners in business management, digital marketing, and the application of renewable energy technology in the form of solar power systems to support cultivation operations. In addition, there was a significant improvement in the quality of management after the training, with participants showing improved financial, marketing, and operational management. The conclusion of this activity is that the application of renewable energy technology and improved management capacity through training and mentoring can successfully support the sustainability of the lobster farming business in Sawarna Village, thus helping farmers to face the environmental and economic challenges faced in the long term.

Abstract

This study evaluates the impact of an earthquake on a mini-hydropower plant (MHP) and formulates a disaster management strategy to enhance the operational resilience of MHPs against seismic events. Data was collected through interviews with relevant stakeholders, direct observations, and analysis of pertinent documents. The findings indicate that the 2018 Lombok earthquake caused severe damage to the catchment area, triggering increased sedimentation that disrupted the MHPs operation, resulting in decreased electricity production and escalated operational costs. Mitigation measures were implemented and proved effective in reducing debris-related downtime and improving electricity generation. Thes findings are expected to provide guidance for MHP operators in mitigating the negative impacts of earthquakes and similar disasters on plant operations.
