Abstract

The research carried out aims to utilize bagasse waste and determine the characteristics of bio-coal briquettes made from bagasse waste with the addition of coal. This research was conducted with reference to a completely randomized design (CRD) with two factors and three replications. The first factor is the comparison of the composition of the main raw materials in the form of bagasse and coal (P) which includes four treatment levels, namely 100%: 0% (P0), 40%: 60% (P1), 60%: 40% (P2) and 80 %: 20% (P3).The second factor is the concentration ratio of tapioca adhesive which includes three treatment levels, namely 10% (K1), 15% (K2) and 20% (K3). There are seven parameters tested in this study, namely density, moisture content, compressive strength, shatter resistance index, calorific value, combustion rate and basic temperature of the cooking pancie when burning briquettes.The results showed that the higher the percentage of coal in the composition of the main raw material tends to increase the compressive strength and decrease the burning rate of the briquettes. Meanwhile, the lower the tapioca adhesive concentration used tends to increase the density, compressive strength, and shatter resistance index and reduce the burning rate of briquettes. The briquettes produced in this study resulted in the following characteristics: briquette density ranged from 0.36 to 0.44 g / cm3, the moisture content ranges from 4.04% - 6.42%, compressive strength ranges from 26.87 - 46.15 N / cm2, the shatter resistance index ranges from 96.02% - 96.78%, the actual heating value ranges from 3266.1 - 4588.5 cal / g, the theoretical calorific value ranged from 1988.1 to 4483.6 cal / g, the briquette combustion rate ranged from 1.818 to 3.125 g / min, and the highest basic cooking pancie temperature was obtained in the P1K1 treatment combination of 229ºC. Keywords:  Briquettes, Coal, Tapioca Glue, Waste Bagasse.

Abstract

The availability of water in the soil varies and is influenced by soil properties, especially those related to the soil's capacity to retain water. Water retention capacity is one of the primary functions of soil, playing a crucial role in maintaining moisture and distributing water to plants. This research aims to analyze the effects of dosage and particle size of oil palm frond biochar on soil infiltration and water retention capacity. The study employed a Completely Randomized Factorial Design (RALF), comprising two factors: the dosage of oil palm frond biochar (A) and the biochar particle size (B). The dosage factor consisted of three levels: 0% (A1), 0.6% (A2), and 1.2% (A3), while the biochar particle size factor consisted of three levels: < 0.5 mm (B1), 0.5 - 1 mm (B2), and 1 - 2 mm (B3). Each experimental unit was replicated three times, resulting in 27 experimental units. The study utilized soil with silt loam texture. The research parameters observed included soil water content at field capacity conditions (pF 2.54) and at permanent wilting point conditions (pF 4.2), changes in water content over time, mass density, particle density, porosity, water infiltration, and water retention capacity. The findings revealed that the addition of biochar to silt loam textured soil resulted in a reduction in infiltration rate, with the most significant reduction observed when applying biochar with a particle size < 0.5 mm (B1). Furthermore, providing biochar with a size of 0.5 – 1 mm at a dosage of 0.6% (B2A2) and a dosage of 1.2% (B2A3) had the effect of increasing the soil's water retention capacity. Keysword : Infiltration, Factorial Completely Randomized Design, Silt Loam, Soil Physical Properties.

Abstract

Mechanical damage is a common issue that affects the quality and marketability of apples during postharvest handling and storage. This study aims to identify mechanical damage in apples using Electrical Impedance Spectroscopy (EIS) as a non-destructive evaluation method. EIS measurements were conducted to analyze the electrical properties of both damaged and intact apples. Results showed that damaged apples exhibited lower extracellular resistance (7.8 kΩ) compared to intact apples (44.67 kΩ), indicating increased electrolyte leakage due to cell membrane disruption. Cole-Cole plot analysis further revealed significant differences in the impedance characteristics of apples, reflecting the extent of tissue damage. These findings demonstrate that EIS effectively detects mechanical damage by assessing changes in cellular integrity. The method provides a rapid, accurate, and non-invasive approach for quality control in apple handling and storage processes. Keywords: Apple, Cell Membrane Integrity, Extracellular Resistance, Electrical Impedance Spectroscopy (EIS), Mechanical Damage.

Abstract

Water is an essential natural resource playing a critical role in human life. Most of the community's needs for drinking water, industry and agricultural irrigation are met from groundwater sources, with agricultural irrigation being the largest user. Central Lampung Regency is dominated by agricultural land and plantations as the main economic sector. Groundwater is a more secure, drought-resistant and easily accessible source, which greatly supports agriculture in this region. This study aims to identify groundwater potential in Central Lampung Regency using remote sensing data and Geographic Information Systems (GIS). Remote sensing applications are employed to assess vegetation density through the Normalized Difference Vegetation Index (NDVI) algorithm. This parameter is then overlaid with other factors, such as soil type, rainfall, land cover, rock lithology, aquifer productivity, slope, and the Topographic Wetness Index (TWI), resulting in a groundwater potential map. Based on the generated groundwater potential map for Central Lampung Regency, it is found that the distribution of groundwater potential is as follows: 0.03% with very high potential, 6.03% with high potential, 84.11% with moderate potential, 9.77% with low potential, and 0.06% with very low potential. Keywords: Groundwater, GIS, NDVI, Remote Sensing
