Abstract

These chemical residues affect the natural balance of soil biota, leading to a decrease in soil pH, areduction in Cation Exchange Capacity (CEC), and a general decline in land productivity. If not treatedpromptly, this damage could harm health and food sustainability. The application of eco-friendlyproducts in modifying soil characteristics, including high-quality zeolite, remains common today. Thisstudy aims to examine the effects of zeolite application on the dynamics of soil chemical characteristicsto promote the development of a sustainable agricultural system. This study employed a RandomizedBlock Design (RBD) containing six different treatments such as five varying recommendation dosagesof zeolite (0.5, 1, 1.5, 2, and 2.5) and one control treatment devoid of zeolite for comparative analysis.Each treatment was reproduced three times, yielding a total of eighteen experimental plots. Soilchemical parameters (pH and CEC) are the primary focus of this experiment. The study's resultsindicated that during the last weeks of testing, applying 1.5 to 2 doses of zeolite proved to be the mostbeneficial, as it continuously raised the pH and CEC levels. Both Pearson and Spearman tests indicatethat the correlation between variables improves from first week to week fourth week. This suggeststhat the effects of the treatment, possibly zeolite application or an alternative treatment, start afterseveral weeks. The results of this investigation indicate that incubation time in zeolite applicationimportant for exhibits effective buffering properties and functions efficiently, significantly improvingthe chemical properties in soil.

Abstract

Abstrak Pemanfaatan limbah kulit kopi menjadi biochar (BIOCHARKOP) merupakan salah satu strategi inovatif dalam pengembangan agribisnis kopi berkelanjutan. Penelitian ini bertujuan untuk menganalisis kelayakan usaha BIOCHARKOP serta prospek ekonominya dalam meningkatkan pendapatan petani kopi di Kabupaten Garut. Metode penelitian yang digunakan adalah pendekatan kuantitatif ekonomi dengan analisis biaya dan pendapatan, kelayakan usaha (R/C ratio dan B/C ratio), titik impas (Break Even Point), serta analisis dampak penggunaan BIOCHARKOP terhadap struktur biaya dan pendapatan usaha tani kopi. Hasil penelitian menunjukkan bahwa usaha BIOCHARKOP memiliki total biaya produksi sebesar Rp1.100.000 per siklus dengan total penerimaan Rp2.000.000, sehingga menghasilkan pendapatan bersih Rp900.000. Nilai R/C ratio sebesar 1,82 dan B/C ratio sebesar 0,82 mengindikasikan bahwa usaha BIOCHARKOP layak dan menguntungkan secara ekonomi. Nilai BEP produksi sebesar 110 kg dan BEP harga sebesar Rp5.500/kg berada di bawah produksi dan harga aktual, yang menunjukkan tingkat keamanan usaha yang tinggi. Selain itu, penerapan BIOCHARKOP pada usaha tani kopi mampu menurunkan biaya pupuk sebesar Rp1.200.000 per musim tanam dan meningkatkan pendapatan petani sebesar Rp1.200.000 atau 8,28%, tanpa meningkatkan biaya tenaga kerja maupun biaya produksi lainnya. Temuan ini menegaskan bahwa BIOCHARKOP berkontribusi signifikan dalam meningkatkan efisiensi biaya dan pendapatan petani kopi. Secara keseluruhan, BIOCHARKOP berpotensi menjadi model usaha berbasis ekonomi sirkuler yang layak dikembangkan untuk memperkuat keberlanjutan dan kesejahteraan petani kopi.Kata kunci: Biochar, Kopi Arabika, Cascara, Limbah Kopi, Pirolisis.AbstractThe use of coffee husk waste into biochar (BIOCHARKOP) is one of the innovative strategies in the development of sustainable coffee agribusiness. This study aims to analyze the feasibility of BIOCHARKOP's business and its economic prospects in increasing the income of coffee farmers in Garut Regency. The research method used is a quantitative economic approach with cost and income analysis, business feasibility (R/C ratio and B/C ratio), break-even point (Break Even Point), and analysis of the impact of the use of BIOCHARKOP on the cost structure and income of coffee farming businesses. The results of the study show that BIOCHARKOP's business has a total production cost of IDR 1,100,000 per cycle with a total revenue of IDR 2,000,000, resulting in a net income of IDR 900,000. The R/C ratio value of 1.82 and the B/C ratio of 0.82 indicate that BIOCHARKOP's business is feasible and economically profitable. The value of the production BEP of 110 kg and the BEP price of Rp5,500/kg is below the actual production and price, which shows a high level of business security. In addition, the application of BIOCHARKOP in coffee farming businesses is able to reduce fertilizer costs by IDR 1,200,000 per planting season and increase farmers' income by IDR 1,200,000 or 8.28%, without increasing labor costs or other production costs. These findings confirm that BIOCHARKOP contributes significantly to improving the cost efficiency and income of coffee farmers. Overall, BIOCHARKOP has the potential to become a circular economy-based business model that is worthy of being developed to strengthen the sustainability and welfare of coffee farmers.Keywords: Biochar, Arabica Coffee, Cascara, Coffee Waste, Pyrolysis.

Abstract

The application of organic amendments is an important strategy to improve seedling quality in coffee nurseries. This study aimed to evaluate the effects of coffee husk compost and biochar, appliedsingly and in combination, on the growth of Arabica coffee seedlings. The experiment was conductedin a nursery using polybags filled with 5 kg of growing media and arranged in a randomized completeblock design with seven treatments and four replications. The treatments consisted of a control, coffeehusk compost alone, biochar alone, and combinations of compost and biochar at different rates.Growth parameters observed included plant height, stem diameter, and number of leaves. The resultsindicated that all amended treatments significantly improved seedling growth compared to thecontrol. The best growth performance was consistently obtained from the combined application ofcoffee husk compost at 300 g polybag⁻¹ and biochar at 200 g polybag⁻¹, which produced the highestplant height, stem diameter, and leaf number. This treatment demonstrated a synergistic effectbetween coffee husk compost as a nutrient source and biochar as a soil conditioner that improved thegrowing media environment. These findings suggest that the combined use of coffee husk compost andbiochar at appropriate rates is an effective approach to enhance vegetative growth and overall qualityof Arabica coffee seedlings in nursery systems.
