Abstract

Jerami padi adalah salah satu sisa tanaman berlignoselulosa yang paling banyak di dunia. Jerami padi umumnya dikelola oleh petani diolah dengan metode pembenaman (straw incorporation) dan dibakar (straw burning). Tujuan dari penelitian ini untuk menentukan dinamika Bahan Organik dan Total Nitrogen Tanah pada pengelolaan jerami padi dan menentukan kandungan hasil mineralisasi Nitrogen setelah perlakuan pengelolaan jerami. Penelitian ini menggunakan Rancangan Acak Pola Tersarang (Nested Design) dengan 3 perlakuan yang terdiri dari pembenaman jerami dengan EM4 (SI), pembenaman jerami tanpa EM4 (SI0), dan pembakaran (BR). Pada setiap blok terdapat 3 kali ulangan di masing-masing ulangan diambil 4 sampel, sehingga total sampel tanah yang diambil berjumlah 36 sampel. Penelitian dilakukan dengan analisis laboratorium sampel tanah sebelum dan sesudah perlakuan pada parameter Bahan Organik Tanah (BOT), Total Kjeldahl Nitrogen (TKN). Kandungan BOT tanah sebelum dan sesudah perlakuan pengeloaan jerami berkisar antara 3,94% - 5.11%, klasifikasi BOT tanah tersebut termasuk sedang-tinggi. Peningkatan BOT tertinggi yaitu 29,7% terdapat pada perlakuan pembakaran. Hal ini dapat disebabkan karena meningkatnya mineralisasi karbon selama proses pembakaran jerami padi. Rata-rata TKN tanah berkisar antara 0,17% sampai 0,39% yang termasuk kategori rendah dan sedang. Analisis Wilcoxon Signed Ranks Test menunjukkan bahwa perlakuan pembenaman jerami dengan EM4 dan Pembenaman jerami tanpa EM4, berpengaruh nyata terhadap TKN tanah (p<0,05). Sebaliknya pada perlakuan pembakaran tidak berpengaruh nyata terhadap TKN tanah (p>0,05). Rice straw is one of the most abundant lignocellulosic plant residues in the world. Farmers typically manage rice straw through incorporation and burning methods. This study aims to determine the dynamics of soil organic matter and total nitrogen in rice straw management and to assess the nitrogen mineralization content following straw management treatments. The research employs a Nested Design with three treatments: straw incorporation with EM4 (SI), straw incorporation without EM4 (SI0), and burning (BR). Each block contains three replicates, with four samples taken per replicate, totaling 36 soil samples. Laboratory analysis of soil samples was conducted before and after treatment on parameters such as Soil Organic Matter (BOT) and Total Kjeldahl Nitrogen (TKN). The SOM content of the soil before and after straw management ranged from 3.94% to 5.11%, which is classified as medium to high. The highest increase in SOM, 29.7%, was observed in the burning treatment, likely due to increased carbon mineralization during the rice straw burning process. The average soil TKN ranged from 0.17% to 0.39%, categorized as low to medium. The Wilcoxon Signed Ranks Test analysis indicated that straw incorporation with EM4 and without EM4 significantly affected soil TKN (p<0.05). Conversely, the burning treatment did not have a significant impact on soil TKN (p>0.05).

Abstract

Determining the ripeness level of oil palm fruit is a crucial aspect in enhancing the efficiency and quality of palm oil production. To date, most ripeness classification processes are still manually conducted, leading to inconsistencies and human error. This study aims to develop an oil palm fruit ripeness classification model using YOLOv8, a state-of-the-art deep learning architecture known for its excellence in computer vision tasks. The dataset consists of six ripeness classes, divided into training, validation, and testing sets sourced from the Roboflow platform. The training process involved five YOLOv8 sub-models with optimized parameter configurations. Evaluation was carried out using MAPE and confidence score metrics to measure prediction accuracy. The results showed that all sub-models successfully classified fruit ripeness with high accuracy, with YOLOv8l-cls achieving the lowest MAPE value of 0.01167. These, confirm that the YOLOv8-based approach is highly effective in supporting automated classification of oil palm fruit ripeness, offering faster, more accurate, and consistent results, and holds strong potential for widespread application in the plantation industry.

Abstract

Strawberry (Fragaria sp.) is a high-value horticultural commodity with broad market potential, particularly in tropical highland areas such as Bedugul, Bali. However, its productivity and fruit quality are often constrained by climatic fluctuations and limited application of appropriate cultivation technologies. This study aimed to evaluate the productivity and fruit quality of Sujarli (Rosalinda) strawberry variety under four cultivation models: conventional open field, tunnel, fertigated open field, and greenhouse. In addition, a predictive model for Total Soluble Solids (TSS) content was developed using fruit color parameters obtained through digital image analysis. A total of 100 strawberry samples across five ripening stages were analyzed for biometrical characteristics (length, diameter, and weight), pH, and TSS. Image analysis was performed in two color spaces, namely RGB and HSV, and the corresponding color values were used as input variables in a multiple linear regression (MLR) model to predict TSS values. The results showed that the fertigated open field system produced strawberries with good physical and chemical quality, making it a feasible option for small-scale farmers. The MLR model based on HSV color space outperformed the RGB-based model, achieving R² values of 0.826 (training) and 0.775 (testing), with lower RMSE values as well. These findings support the use of digital color data as a non-destructive indicator for assessing the quality of strawberries during postharvest evaluation.
