Abstract

This research presents a comprehensive analysis of various imputation methods for addressing missing microclimate data in the context of coffee-pine agroforestry land in UB Forest. Utilizing Big data and Machine learning methods, the research evaluates the effectiveness of imputation missing microclimate data with Interpolation, Shifted Interpolation, K-Nearest Neighbors (KNN), and Linear Regression methods across multiple time frames - 6 hours, daily, weekly, and monthly. The performance of these methods is meticulously assessed using four key evaluation metrics Mean Absolute Error (MAE), Mean Squared Error (MSE), Root Mean Squared Error (RMSE), and Mean Absolute Percentage Error (MAPE). The results indicate that Linear Regression consistently outperforms other methods across all time frames, demonstrating the lowest error rates in terms of MAE, MSE, RMSE, and MAPE. This finding underscores the robustness and precision of Linear Regression in handling the variability inherent in microclimate data within agroforestry systems. The research highlights the critical role of accurate data imputation in agroforestry research and points towards the potential of machine learning techniques in advancing environmental data analysis. The insights gained from this research contribute significantly to the field of environmental science, offering a reliable methodological approach for enhancing the accuracy of microclimate models in agroforestry, thereby facilitating informed decision-making for sustainable ecosystem management.

Abstract

Arabica coffee is primarily cultivated in agroforestry systems in Indonesia, but limited local knowledge and technology adoption hinder its productivity due to insufficient practices in coffee pruning management. This study aims to analyze variations in coffee canopy pruning (Pruning+Bending) management and the impact on plant growth and soil physical characteristics.. The experiment employed a split-plot experimental design and utilized the Fisher test (5%) to assess the treatment effects. The primary plot focused on coffee canopy pruning using two management options: (1) Pruning (PR) and (2) Bending (BN). The subplots included various types and doses of fertilizer treatments: (1) Control (F0), (2) Chicken manure (F1), (3) Chicken manure+NPK fertilizer (F2), and (4) NPK fertilizer (F3). Each experimental plot covered an area of 20x20 m and contained 50 coffee plants. Bending techniques represent alternative pruning methods, and, in general, they have a significant impact on improving several coffee parameters compared to total pruning. Regarding the soil’s physical properties, the bending technique exhibited a higher infiltration rate than pruning. The management approach of Bending+Chicken manure: NPK fertilizer (BNF2) enhanced various coffee parameters, resulting in an increased stem diameter of 4.79 cm, new shoot length of 471.20 cm, and chlorophyll content of 6.83 mg/g. Furthermore, this treatment increased soil organic carbon content by 7.51% and reduced bulk density to 0.58 g/cm. In conclusion, the bending technique wasproven to be more advantageous than pruning, especially when combined with chicken manure and NPK fertilizer for enhancing coffee management among farmers.

Abstract

Sago farmers from the Mooi tribe in Sorong Regency - Southwest Papua have consumed and cultivated sago for generations. This research aims to understand the local ecological knowledge (LEK) of sago farmers in managing their land to maintain soil quality in sago agroforestry, compared with modern/scientific environmental understanding. The survey was conducted from February to October 2021 in three sub-districts, Sorong Regency, using an exploratory descriptive method among Mooi sago farmers. Intact soil samples were taken to measure soil physical properties and disturbed soil samples to analyze soil chemical properties (pH, C-Organic, Total N, P, K, CEC, base saturation). The results of this research show that what sago farmers have in common with the unique habits of the Mooi tribe's harvest system is that they harvest enough sago starch to consume or sell if there is too much of it. According to sago farmers, the best land for growing sago is close to a water source and is not affected by soil biota and fertilization. and sago farmers will leave ella sago dregs on the land. Meanwhile, according to MEK, starch formation decreases in flooded land and the remaining sago dregs are very good for making compost and animal feed. In sago forests where sago grows naturally, the soil texture is dominated by silt, having a pH of 5.8-7.2; High total organic C 2.8-5.2%, P 14.08-66.44 mg/kg, K 755.3 – 1626.8 mg/kg, CEC 18-40 cmol(+)/kg, and base saturation 30 – 134%. These values are relatively higher than on land with a sago-based agroforestry system.

Abstract

High-traffic highway crossing agricultural fields impacts the quality of food crops grown on Vertisol agricultural fields in Pasuruan. Lead (Pb) released from the exhaust of motor vehicles into the air can eventually enter the soil and be absorbed by plants. This study aimed to examine the effect of Pb from exhaust motor vehicles emission on the Pb status and its behavior in soil, water, and plants. The study was initiated by conducting a survey to determine the sampling locations in selected inundated paddy and maize cropping systems. A stratified random sampling method was used to collect soil, water, and plant samples. The soil of the study area is dominated by Vertisol, with clay content ranging from 54% to 76%. The soil attributes a high cation exchange capacity ranging from 80.53 meq 100 g-1 to 93.57 meq 100 g-1. Pb emitted from 2,913,000 vehicles within four months period that entered the agricultural field was not absorbed by paddy and maize crops. Pb entered the soil in the adsorbed form, and no Pb was observed in the soluble form, so it was not absorbed by the roots. In the paddy field, the total Pb of 84.33% was influenced by pollutant distance. Likewise, in the maize field, 83.18% of total Pb was influenced by pollutant distance. The far the pollutant distance from the agricultural field, the lower its total Pb. Paddy field water is adsorbed onto the colloidal clay, which is dispersed due to inundation and sloughing of the paddy, moving with the clay and then dissolved in the water flow.

Abstract

Monitoring  lemon production requires appropriate and efficient technology. The use of UAVs can addressed these challenges. The purpose of this study was to determine the best vegetation indices (VIs) for estimating chlorophyll content, plant height (PH), canopy area (CA), and fruit total numberas (FTN). CCM 200 was used as a tool to measure the chlorophyll content index (CCI), the number of fruits was measured by hand-counter, and other variables were recorded in meters. The UAV used was a Phantom 4 with a multispectral camera capable of capturing five different bands. The VIs was obtained via analysis of digital numbers generated by the multispectral camera. Then, the VIs was correlated with the CCI, PH, CA and FTN. VIs tested included the following: the normalized difference vegetation index (NDVI), the normalized difference vegetation index-green (NDVIg), the normalized different index (NDI), green minus red (GMR), simple ratio (SR), the Visible Atmospherically Resistant Index (VARI), normalized difference red edge (NDRE), simple ratio red-edge (SRRE), the simple ratio vegetation index (SRVI), and the Canopy Chlorophyll Content Index (CCCI). The best model for predicting CCI was obtained using the NDVIg (R2=0.8480; RMSE=6.1665 and RRMSE=0.0908). Meanwhile, SR turned out to be the best model for predicting PH (R2=0.8266; RMSE=15.6432 and RRMSE=0.0883), CA (R2=0.6886; RMSE= 0.8826 and RRMSE=0.1907), and FTN (R2=0.6850; RMSE=24.5574 and RRMSE=0.3503). The implication of these results for future activities includes establishing early monitoring and evaluation systems for lemon yield and production. This model was developed and tested in this specific location and under these environmental conditions.

Abstract

Logging activities in pine production forests create open land that increases surface runoff and soil erosion, highlighting the need for soil conservation during the early stages of agroforestry development. This study evaluated the effectiveness of mechanical and vegetative conservation practices, including biogeotextiles, in reducing runoff and erosion and improving plant growth and farm profitability in an early-stage pine–durian agroforestry system. A randomized factorial block design with two factors and a non-factorial control was applied. Mechanical conservation treatments included no terraces, ridge terraces, and bench terraces, while vegetative conservation treatments consisted of chili monoculture, peanut monoculture, chili–peanut intercropping, and intercropping combined with biogeotextiles. Results showed that mechanical conservation significantly reduced runoff and erosion, with bench terraces providing the greatest reductions (33–53% runoff; 48–75% erosion), followed by ridge terraces. Biogeotextiles further reduced erosion by up to 68%, although they increased implementation costs. Pine and durian growth were not significantly affected, whereas chili productivity increased under intercropping and terraced systems. Economically, bench terraces produced the highest profitability (R/C >6). Overall, integrating mechanical and vegetative conservation effectively improved hydro-logical function, crop productivity, and farm income in pine–durian agroforestry systems.

Abstract

Penurunan produktivitas tebu di Indonesia kerap berkaitan dengan rendahnya kualitas tanah, terutama akibat minimnya bahan organik dan dominasi pemupukan anorganik. Penelitian ini bertujuan untuk mengetahui pengaruh kombinasi pupuk hayati dan pupuk anorganik terhadap sifat kimia-biologi tanah serta pertumbuhan tanaman tebu varietas Bululawang. Rancangan yang digunakan adalah rancangan acak kelompok (RAK) nonfaktorial yang terdiri dari 12 kombinasi perlakuan dosis pupuk anorganik (0%, 50%, 100%) dan jenis pupuk hayati (tanpa pupuk hayati, Fertomax, Bioneensis, serta kombinasi keduanya). Data yang diperoleh kemudian dianalisis menggunakan analisis ragam (ANOVA) taraf 5% dan apabila berpengaruh nyata dilakukan uji lanjut BNT pada taraf 5% . Parameter yang diamati meliputi tinggi tanaman, diameter batang, pH tanah, N-total, P-tersedia, dan total populasi bakteri. Hasil penelitian menunjukkan bahwa kombinasi pupuk hayati dan anorganik berpengaruh nyata terhadap pH tanah, P-tersedia, dan populasi bakteri tanah, namun tidak berpengaruh nyata terhadap tinggi tanaman dan N-total tanah. Perlakuan PA100FB (pupuk anorganik 100% + Fertomax + Bioneensis) merupakan perlakuan terbaik karena menghasilkan P-tersedia tertinggi (40,86 ppm) dan populasi bakteri tertinggi (9,58 log CFU g⁻¹).

Abstract

Produksi gula nasional belum mampu memenuhi kebutuhan gula dalam negeri sehingga Indonesia masih bergantung pada impor. Sementara itu, produktivitas tebu, terutama di Jawa Timur masih fluktuatif. Kondisi ini tidak sejalan dengan peningkatan luas lahan tebu yang terus meningkat. Salah satu faktor pembatas produktivitas tebu adalah kondisi vertisol yang umumnya memiliki bahan organik rendah. Hal ini mempengaruhi kualitas tanah terutama sifat kimia dan biologi tanah. Penelitian ini bertujuan untuk menganalisis pengaruh berbagai jenis bahan organik tunggal dan kombinasi terhadap sifat kimia dan biologi vertisol. Penelitian menggunakan Rancangan Acak Kelompok non-faktorial dengan sembilan perlakuan, yang terdiri dari tanpa bahan organik, sekam bakar, abu ketel, blotong, seresah tebu, serta kombinasi antar ketiganya pada dosis setara 20 t ha⁻¹. Parameter yang diamati meliputi C-organik, N-total, rasio C/N, pH H2O, serta populasi bakteri dan jamur tanah. Hasil penelitian menunjukkan bahwa perlakuan kombinasi sekam bakar 10 t ha⁻¹ + abu ketel 10 t ha⁻¹ (P5) memberikan peningkatan terbaik terhadap C-organik dan populasi jamur. Sementara itu, kombinasi sekam bakar 7 t ha⁻¹ + abu ketel 7 t ha⁻¹ + blotong 7 t ha⁻¹ (P8) merupakan perlakuan paling efektif dalam meningkatkan populasi bakteri.

Abstract

Digital transformation has encouraged micro, small, and medium enterprises (MSMEs) to adopt digital branding strategies to strengthen brand identity and enhance customer loyalty. However, implementing digital branding in emerging MSMEs remains challenging due to limited resources, digital competencies, and brand communication consistency. This study explores digital branding strategies for fostering customer loyalty at Kopi Pak Kopral, an emerging MSME in Pasuruan, Indonesia. A qualitative case study design was employed. Data were collected through semi-structured interviews with the business owner and social media manager, as well as open-ended questionnaires administered to customers, and analyzed using the interactive model of Miles, Huberman, and Saldaña. The findings indicate that digital branding was implemented through four key approaches: maintaining a consistent brand identity, developing storytelling around the product and local values, establishing interactive digital communication through social media and WhatsApp Business, and utilizing customer testimonials as social proof. These strategies strengthened brand trust, customer engagement, and customers’ emotional connections with the brand, thereby encouraging repeat purchases, recommendations, and loyalty. The study concludes that digital branding functions not merely as a promotional tool but also as a strategic means of developing long-term customer relationships. The findings offer practical implications for MSMEs seeking to optimize digital marketing strategies and contribute to the literature on digital branding in emerging MSMEs.
