Abstract

Soil color is a crucial property in soil fertility assessment and monitoring. However, the subjective nature of the Munsell Soil Color Chart (MSCC) can lead to uncertainty in the analysis. To address this issue, a study was conducted to develop a soil color classification model from smartphone digital imagery based on color analysis and MSCC. The study involved taking 26 soil samples from various soil types and locations in the Special Region of Yogyakarta, Indonesia. Digital images of the soil were taken through a smartphone camera and compared with observations using MSCC to compare color differences (ΔE) based on Lab values. Soil images obtained from indoor studio conditions and calibration using spydercheckr in indoor and outdoor conditions are compared with MSCC and Chromameter values. The L*a*b color space was found to be superior to RGB for predicting and detecting small differences in color. The study also found that the Munsell soil color chart (MSCC) had a lower color difference than the chromameter in all lighting conditions, indicating that the MSCC or visual assessment can better detect the main soil color or soil matrix, while chromameter readings may have errors due to soil impurities.

Abstract

Laboratory analysis is commonly used to determine nitrogen and chlorophyll content. However, smartphones can serve as rapid, mobile, and non-destructive tools for this purpose. An equation can be created to calculate nitrogen and chlorophyll content by analyzing color parameters from digital images of rice leaves. An examination was performed on 86 rice leaf samples from the maximum tillering and mature stages. Rice leaf photos were taken with a smartphone in natural outdoor lighting. Color calibration with Spydercheckr was needed to adjust for lighting conditions. Uncalibrated and calibrated image data were analyzed to determine RGB values converted into CIELAB color space. The L*, a*, and b* values had a significant correlation with SPAD parameters, nitrogen concentration, chlorophyll a, b, and total chlorophyll content. This connection was higher after image calibration. The study found that smartphone images could predict SPAD values with 87.9% to 92.3% precision, depending on color space. Using a smartphone digital picture of L* and a* values, N content could be estimated with 84.7% and 81.9% accuracy. Average accuracy for chlorophyll a, b, and total chlorophyll content was 65% to 76%. This study shows smartphone images can estimate rice leaf SPAD and nitrogen content.

Abstract

Isu kehilangan minyak sawit akibat rangkaian proses pada pabrik kelapa sawit merupakan permasalahan yang perlu diatasi. Sludge centrifuge merupakan unit penyaring pada stasiun klarifikasi yang dapat menurunkan losses minyak. Penelitian ini bertujuan untuk mengetahui efektivitas sludge centrifuge dalam mengutip minyak di PT. Eka Dura Indonesia. Sampel sebanyak 100 ml diambil dari buffer tank sebagai input pada sludge dengan kandungan minyak (14,53%), emulsi (10,93%), air (60,33 %) dan NOS (20,60%). Keluaran dari sludge centrifuge berupa light phase dan heavy phase. Light phase memiliki komposisi (13,47%), emulsi (10,50%), air (59,10%) dan NOS (16,93%). Heavy phase terdiri dari oil wet basis (OWB) dan oil dry basis (ODB). Oil wet basis (OWB) merupakan penanda terjadinya kehilangan minyak. Hasil penelitian menunjukkan bahwa OWB/minyak sebesar 0.82%. Hal tersebut sesuai dengan standar yang ditetapkan oleh pabrik yakni dibawah 1 %. Selanjutnya kandungan minyak total pada sludge umpan memiliki korelasi positif dengan kandungan minyak light phase sludge centrifuge (R = 0,996).

Abstract

The empowerment of farmers in Ketep Village, Sawangan, Magelang is an important step to increase their independence, creativity, and productivity. In addition to being involved in coffee processing, farmers in this area are also active in vegetable cultivation. However, the coffee processing process produces liquid waste with a very acidic pH if it is directly discharged into water bodies or soil, which can damage the environment and negatively impact the quality of the plants grown and endanger consumer health. Coffee liquid waste contains high organic matter, which can increase Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) in waters if disposed of carelessly. To overcome this problem, we propose a community service program that utilizes vetiver-based biogardens as a method of liquid waste management. As a PKM partner in this service is the "Beringin Farmers Group" in Ketep Village, Sawangan District, Magelang. The results of the survey on the understanding of the use of vetiver grass as an absorption of coffee processing liquid waste show that a small percentage of respondents do not fully understand or are interested in this topic. Most of the respondents were in the category of high understanding or interest (score 4-5), which indicates a significant impact of counseling. The results of the observations showed that the filtration of coffee liquid waste using vetiver grass succeeded in significantly lowering the pH, BOD, and COD. This filtration process increases the pH of the waste from 4 (acidic pH) to 7 (neutral pH). The content of BOD and COD decreased significantly from week 0 to week 3, which suggests that vetiver root is effective in reducing the content of organic matter and harmful chemical compounds in coffee liquid waste.

Abstract

The natural, full-wash, and honey processing methods, along with fermentation duration, significantly influence the chemical components and flavour profile of the resulting coffee. Therefore, it is essential to conduct research to determine the chemical and flavour characteristics produced by each processing method to maintain quality and ensure flavour consistency. The research design employed is a complete two-factor block design. The first factor is the variation in processing methods: natural, full-wash, and honey. The second factor is fermentation duration: 18 h, 24 h, and 30 h. The analyses performed include moisture content, ash content, pH, lipid content, protein content, total acid content, caffeine content, and sensory evaluation using the SCAA method. The results of this study indicate that variations in processing methods affect the values of moisture content, protein content, caffeine content, lipid content, and total acid content. Similarly, the fermentation duration of coffee cherries affects the moisture content, protein content, caffeine content, lipid content, and total acid content. The study also shows a relationship between the variations in processing methods and the fermentation duration of coffee cherries. The honey processing method and optimal ripeness levels were most preferred by the panelists. All the coffee produced in this study has met the SNI 01-3542-2004 standard.

Abstract

Legal Aid Post (Posbakum) is a legal aid institution funded by the state through religious courts. This institution aims to provide free legal aid for people who cannot afford to get justice. This study uses a descriptive analysis method to examine the role, challenges, and effectiveness of Posbakum in handling divorce cases. Posbakum at the Purworejo Religious Court has a strategic role in helping the community, especially the less fortunate, to access justice in divorce cases. Posbakum services include free legal consultations, document assistance, and legal information. However, several challenges such as lack of public awareness, limited understanding, and ineffective coordination with related parties still need to be overcome. Research shows that the main causes of divorce in Purworejo are prolonged conflict, financial (economic) problems, and domestic violence. In order to improve the effectiveness of Posbakum in handling divorce cases, the existing challenges must be overcome immediately. Although Posbakum has a very strategic role, efforts still need to be made to improve its performance in helping the community, especially in matters of divorce
