Abstract

Palm oil mill effluent (POME), discharged by palm oil processing industry, is potentially recovered as substitution of AB mix, a nutrient solution for hydroponic. The objective of this research is to test the use of the treated POME in the mixture with AB mix to cultivate green mustard. The method in this study uses a factorial Completely Randomized Design (CRD) with 2 factors.  The first factor, namely POME (K) consists of 2 levels, namely Pond 3 (K3) and Pond 4 (K4).  The second factor is the mixture of AB Mix and POME, which consists of 5 levels of the POME percentages namely: 0% (P0), 25% (P25), 50% (P50), 75% (P75), and 100% (P100). Results showed that the increasing percentages of POME additions tended to decrease the growth of green mustard. The best treatment was obtained on treatment of P0, 100% AB mix with no POME addition based on plant height, number of leaves, and water consumption. Keywords: AB Mix, Green Mustard, Hydroponic, POME, Wick System

Abstract

Cilembu sweet potato production in Lampung reached 28,494,000 tons/year (2015 statistical data). The selling price of Cilembu sweet potatoes in traditional markets is low, ranging from IDR 4,000 to IDR 10,000/Kg. Therefore, it is necessary to carry out appropriate processing in order to increase the selling price of Cilembu sweet potatoes. One way that can be done is by making Cilembu sweet potatoes into a chips product using a Vacuum Frying fryer. A vacuum fryer is a vacuum fryer which has the advantage of frying fruit and vegetables into crispier chips and maintaining product quality without preservatives. The aim of this research is to analyze the influence of temperature and pressure on the results of frying Cilembu sweet potato chips using a Vacuum Frying fryer and determine the optimal temperature and pressure needed to produce the best quality Cilembu sweet potato chips. The research method used was a factorial Completely Randomized Design (CRD). The experimental factors in this study used two factors, temperature (T), namely 80°C,  85°C,  90°C and pressure (P) -66 cmHg, -68 cmHg, -70 cmHg, with repetition 3 times to produce 27 experimental units. The parameters observed were material weight loss analysis (random), water content, and sensory tests. It can be concluded that the optimal choice of temperature and pressure in operating the Vacuum Frying tool for frying Cilembu sweet potato chips is a temperature of 90°C and a pressure of -68 cmHg. The quality of frying pans with a temperature of 90°C and a pressure of -68 cmHg is included in the best product category in this research based on overall acceptance which has a yield value of 35%, water content of 3.3%, and a color sensory test score of 3.75 (yellow), aroma 2.95 (the aroma of Cilembu sweet potato chips is a bit strong), taste 4.25 (like it), crunchiness 4.2 (crisp). Keywords:  Chips, Cilembu Sweet Potato, Vacuum Frying.

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

This study aims to generate a landslide susceptibility map for Balik Bukit District using geospatial data and analyze the vegetation density from Sentinel 2-A and Landsat 8 OLI imagery to support the identification of landslide-prone areas. The study used SHP data for various parameters including Rainfall, Slope, Geology, Land Cover, Soil Type, and NDVI (Normalized Difference Vegetation Index). The final results consist of thematic maps and a landslide susceptibility map, illustrating the area's risk levels. GIS played a crucial role in mapping, calculations, and analysis. Five landslide susceptibility classes were derived from both Sentinel and Landsat imagery. Sentinel 2-A indicated 1991 Ha as not prone, 6905 Ha as low, 6174 Ha as moderate, 2468 Ha as high, and 710 Ha as very high. Landsat 8 OLI classified 1612 Ha as not prone, 6231 Ha as low, 6899 Ha as moderate, 2565 Ha as high, and 941 Ha as very high. Both imagery types identified Desa Kubu Perahu as very high risk but with different areas: Sentinel 2-A at 169 Ha and Landsat 8 OLI at 215 Ha. Vegetation density significantly influences landslide susceptibility, with Sentinel providing more detailed data, indicating 61 Ha as very sparse compared to 39 Ha by Landsat. Rainfall and Slope are the most dominant factors affecting landslide risk, followed by Geology, Soil Type, Land Cover, and Vegetation Density. Keywords:  GIS, Landslide, Lansat 8 OLI, Sentinel,  NDVI

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.
