Abstract

Salah satu sumber energi baru terbarukan yang memiliki potensi untuk dikembangkan yaitu pemanfaatan energi air sebagai pembangkit listrik. Implementasi dari Pembangkit Tenaga Listrik Pikohidro sangat cocok dengan wilayah alam yang berada di Kalimantan Selatan yang banyak memiliki aliran air, seperti sungai, irigasi, air terjun, bendungan dan lainnya. Sebuah pengembangan tentang Pembangkit Listrik Tenaga Pikohidro diperlukan untuk implementasi di wilayah terpencil Kalimantan Selatan yang energinya dapat menerangi irigasi pada malam hari ataupun kebutuhan sehari-hari. Penelitian ini bertujuan untuk mengetahui performa Pembangkit Listrik Tenaga Pikohidro Archimedes Screw dengan menggunakan debit andalan irigasi Instalasi Buididaya Ikan Desa Bincau. Hasil pengujian dengan debit 47,88 ltr/dtk, dengan Level Rendaman (I) 0,7 serta Kemiringan 11° menghasilkan Putaran diangka 301 rpm dengan Torsi (ז ) sebesar 2,82 Nm.

Abstract

By the development in technology especially in architecture and industry with its noise activity, encourage us to do some efforts to solve noise problem. One might done is utilize pumice as noise absorber. Raw material used in this reaserch is pumice ash. Mixing compotsition variation between cement composition, pumice ash as sand subtitution, with comparison mixing composition at 1 : 6 (1 cemen : 6 ash), 1 : 8 (1 cement : 8 ash :), 1 : 10 (1 cement : 10 ash). Sound absorbtion coefisien are measured by standing wave tube apparatus. The result of the research indicates that mixing composition affects the sound absorbtion coefisien. Reaserch shows taht 1 : 6, 1 :8 and 1 : 10 sound absorbtion coefisien which is 0.96, 0,86 and 0.89 in 8000 Hz frequency. Comparison at 1 : 6, 1 : 8 and 1 : 10 (cement : sand ) has the best absorbtion coefisien at comparation 1 : 10 which is 0.98 with 4000 Hz frequency (middle level frequency).

Abstract

Utilization of waste rice husk, especially in South Kalimantan, is not very efficient. Therefore, it needs more maximal utilization, for example it is used to manufacture alternative fuels in the form of charcoal briquettes. The effort to maximizing utilize waste rice husk as charcoal briquettes, we need to know the combustion characteristics. The study, we used a variation of the ratio between siam rice husk charcoal in the peat region areas and pandak is located in the tidal areas with adhesives of 5%, 10% and 15% respectively. Characteristics of testing follows SNI 01-6235-2000. Based on the results of the study, it is known that the charcoal waste of rice husk waste with a percentage of 5% adhesive has a good value compared to the addition of other adhesives, where siam rice husk has a water content of 4.9% and pandak has a higher moisture content of 5.0%, whereas for husk heating values Pandak rice is larger with a value of 5063.6 cal / gram, compared to siam rice husk with a value of 4894.5 cal / gram.

Abstract

Penelitian ini merupakan penelitian lanjutan dari penelitian sebelumnya. Konversi dari bahan bakar minyak ke bahan bakar gas jenis LPG (Liquified Petroleum Gas) dengan menggunakan sistem injeksi tipe 1. Sistem injeksi tipe I atau disebut dengan manifold injection merupakan desain injeksi yang paling sederhana pengganti sistem karburator, dimana sistem ini diharapkan mampu memperbaiki pasokan bahan bakar yang dibutuhkan oleh mesin. Torsi dan daya mesin diperoleh dengan menggunakan peralatan chasis dynamometer. Bahan bakar yang digunakan dalam penelitian ini yaitu menggunakan bahan bakar minyak jensi premium dan bahan bakar gas jenis LPG. Hasilnya menunjukkan bahwa dengan menggunakan bahan bakar LPG injeksi tipe 1, terjadi penurunan torsi, daya mesin, dan spesifik konsumsi bahan bakar pada single cylinder spark ignition. Akan tetapi efisiensi thermal meningkat sebesar 6,38% dibandingkan dengan bahan bakar premium.

Abstract

Micro-hydro power plants take advantage of the energy potential of low-head airflow. with the development of technology that can support it, namely the Archimedes screw turbine as the driving force. Various parameters must be considered to determine the performance of micro hydro power plants with Archimedes screw turbines. A design is carried out with a discharge parameter flow rate of 2 l/s, a turbine slope of 300, and an immersion level variation of 0.3, 0.5, and 0.7, where the final result shows the value of torque, hydraulic power, mechanical power, generator, and efficiency, which decreases with the level of water immersion in the last blade.

Abstract

Since plastic and food waste are both types of non-lignocellulosic biomass, these must be handled and managed correctly to avoid pollution problems and damage to the environment. Bio-oil, made from recycled materials, including plastic and food waste, is one focus of these attempts. The co-pyrolysis method is being investigated in this study as a technique of recycling plastic waste and food waste to produce biofuels with reduced environmental impact. In terms of energy efficiency, bio-oil is unequal to other fuels like coal or natural gas because of its high acidity, high oxygen content, and low thermal stability. Therefore, a vacuum distillation process is required to improve bio-oil quality by adjusting the distillation temperature from 300 to 350 OC and the percentage of plastic waste used from 30 to 50%. The bio-oil was analyzed using a Gas Chromatography-Mass Spectrometer (GC-MS). The general compound showed that acids (60%) and alcohols (20%) were the most prevalent chemical compounds, followed by phenol (4%), aldehyde (14%), aliphatic (5%), Furan (14%), and ketones (11%) at maximum temperature (350 oC) for 30-50% plastic waste. Meanwhile, the final product is affected by temperature and plastic waste (PET) ratio factors. At 350 °C and a plastic waste addition of 50%, the highest bio-oil yield is 45%.

Abstract

Constructing a small-scale hydroelectric power station that can run efficiently at a head lower than 10 m is one possible method for reducing the impact of the electricity crisis in remote areas of Indonesia. The Archimedes Screw turbine is one type of turbine that is ideal for discharges below 10 m. In this study, the simulation results show that the value of Turbulences Kinetic Energy is directly proportional to the increase in flow rate but inversely proportional to the level of immersion. This type of turbine is unless well in Indonesia due to a lack of information regarding the application of low head power plants. The turbine model that is suitable for the low head is investigated in this study. Before being tested, the turbine is first designed theoretically and then numerically evaluated. With discharges of 1 l/s, 2 l/s, and 3 l/s and turbine immersion levels of 30%, 50%, and 70%, ANSYS CFD (Computational Fluid Dynamic) software was used to investigate flow rate and level of immersion in the turbine. According to the investigation findings, the discharge has a considerable impact on the turbine's movement; the higher the flow rate, the higher the power to the turbine, which produces a torque on the turbine. The simulation findings indicate that the value of Turbulence Kinetic Energy is proportional to the increase in flow rate but inversely proportional to the level of immersion.
