Abstract

The waste problem in Bandar Lampung is becoming increasingly critical as the volume of domestic waste reaches 1,283 tons per day. Ineffective management can lead to negative impacts on public health and the environment, such as the spread of diseases and pollution. This study aims to design and test a household-scale incinerator that is effective, efficient, safe, and low in pollution as an alternative solution for waste management. The designed incinerator is capable of burning 30 kg of waste in 180 minutes, using a fuel mixture of used oil and gasoline amounting to 130 ml. Test results show that the thermal efficiency of the incinerator ranges from 70-75%, with a charcoal yield of 14.42% and an ash yield of 11.53%. The overall efficiency reaches 77.05%, indicating that this device can optimally utilize the energy produced from combustion. This research demonstrates that a household-scale incinerator can be an effective solution for reducing waste volume and minimizing negative impacts on the environment. Recommendations for future research include the development of the incinerator design, evaluation of the temperature control system, and analysis of emissions generated from various types and compositions of waste. Thus, this study makes an important contribution to more environmentally friendly and sustainable waste management in Indonesia. Keywords: Combustion, Development, Design, Incinerator, Waste, Used Oil, Yield.

Abstract

Catfish (Clarias gariepinus) is a type of fish that is widely cultivated in Indonesia. People in Lampung Province really like catfish with a consumption level of 17.10% of total household fish consumption. Catfish have a high water content so they are easily damaged. One way to preserve is smoking. The smoking process uses fuel to produce smoke and uses a drum type smoker. This research aims to determine the type of fumigation fuel that is effective for carrying out fumigation according to SNI quality. The parameters observed were water content, yield, amount of fuel used, and organoplastic tests (appearance, aroma, taste and texture). Then the data was analyzed using Microsoft Excel and continued with the BNT test. The results showed that A3 treatment with a mixture of charcoal and coconut fiber produced the best quality smoked catfish with a water content of 40.54%, with a sensory value of appearance of 8.3, smell of 8.7, taste of 8.7 and texture of 8.5. and the amount of fuel used was 6.03 kg. Keywords: Catfish, Coconut Fiber, Smoked, Wood Charcoal.

Abstract

The poultry industry in Indonesia is growing rapidly, but still relies heavily on the supply of seeds and feed raw materials from abroad. The abundant meat production leaves innards or chicken carcasses in large quantities.  The use of chicken innards into animal feed is one of the fulfillments of the supply of animal feed availability because it contains enough protein.  Because the period of decomposition of meat occurs quickly, so to overcome this, it is necessary to dry the dried innards in order to stay durable.  This study aims to determine the characteristic value and water content of the equilibrium drying of chicken innards thin-layer as well as observe the color changes of chicken innards.  The study was conducted by an experimental method with two treatments, namely drying temperature and innards type.  The analyses carried out are water content, equilibrium water content (Me), drying constant (k), protein, and color. From the results of the study, it was found that the type of innards (gizzard, liver, and intestine) affects the drying time, final water content, protein, and color but does not affect the equilibrium water content (Me), and the drying constant.  While the drying temperature used affects all observed parameters.  High temperatures (90°C) produce brighter colors because the drying process is shorter. Keywords: Chicken innards, Color, Layer Drying, Thin Protein.
