Abstract

According to data from the Kementerian Lingkungan Hidup dan Kehutanan (2022), waste production in Indonesia is around 36 million tons per year and unmanaged waste is around 13.5 tons per year (37.45%). Waste production in Daerah Istimewa Yogyakarta is around 800 thousand tons per year, and  50.17% of it is household waste. The total volume of waste brought to the Piyungan landfill is around 700 tons/day, around 55 percent of it is organic waste. Each person produces around 0.68 kg of waste per day, so waste management must be the responsibility of all people communities as waste producers. The aim of community service activity is to increase knowledge, skills and motivate also raise awareness of KWT Cabe Rawit members in Jambon Village as partners in processing household waste into eco enzyme and Liquid Organic Fertilizer using the stacked bucket technique, so that it can support the zero waste movement. The implementation methods in community service activities including lectures, training and practice. The outputs that will be produced are publications in national seminar proceedings with ISBN, publications in electronic mass media, books with ISBN, videos, posters and increasing partner empowerment. All members of the KWT Cabe Rawit members in Jambon Village understand and are skilled in making eco enzymes and Liquid Organic Fertilizer from organic household waste and their benefits. The quality of Liquid Organic Fertilizer using the stacked bucket technique is an organic C content of 2.76%, 0.14% total N, C/ N 19.71, P2O5 0.0041 %, K2O 0.023% and pH 5.7. The quality of compost using the stacked bucket technique is organic C content 42.26%, total N 3.67%, C/N 11.51, P2O5 0.39%, K2O 0.17% and pH 6.2 and pH eco enzyme 3 .5Keywords: Eco enzyme, Household waste, Liquid organic fertilizer, Zero waste

Abstract

Potensi tanah marginal dan tanah yang didominasi fraksi pasir menyimpan hara tanah relatip rendah karena fraksi pasir berpotensi mempunyai pelindian tinggi. Kombinasi pemberian bahan dari luar (ameliorance) biochar tempurung kelapa dan pupuk urin domba merupakan salah satu alternatif dalam mempertahankan ketersediaan hara pada tanah pasiran. Tujuan penelitian untuk mengetahui pengaruh biochar tempurung kelapa dan pupuk urin domba terhadap serapan hara N dan P bagi tanaman Pakcoy di tanah pasir Pantai Samas. Penelitian dilakukan di rumah kaca Fakultas Pertanian Universitas Pembangunan Nasional “Veteran” Yogyakarta dan dilakukan analisis di labolatorium Program Studi Ilmu Tanah Fakultas Pertanian Universitas Pembangunan Nasional “Veteran” Yogyakarta pada bulan Juni 2021 sampai Januari 2022. Percobaan menggunakan Rancangan Acak Lengkap (RAL) dua faktor. Faktor pertama adalah dosis biochar tempurung kelapa terdiri dari B0: 0 ton/ha, B1: 10 ton/ha, B2: 15 ton/ha, dan B3: 20 ton/ha. Faktor kedua adalah dosis pupuk urin domba terdiri dari U0: 0 ml/l air setara 0 lt/ha, U1: 100 ml/l air setara 125 lt/ha, dan U2 : 200 ml/l air setara  250 lt/ha. Parameter penelitian adalah pH, N-Tersedia, P-tersedia, serapan hara N bagian atas, serapan hara N akar dan serapan hara P bagian atas. Hasil penelitian dianalisis dengan Analysis of Varians (ANOVA), dilanjutkan dengan DMRT 5%. Hasil penelitian menunjukkan pupuk urin domba 100 ml/l air berpengaruh nyata meningkatkan serapan hara N bagian atas dari 2,15 mg/tanaman menjadi 3,37 mg/tanaman, serapan hara N akar dari 1,16 mg/tanaman menjadi 1,84 mg/tanaman, serapan hara P bagian atas dari 1,03 mg/tanaman menjadi 1,43 mg/tanaman, dan serapan hara P akar dari 0,1 mg/tanaman menjadi 0,19 mg/tanaman. Biochar tempurung kelapa 20 ton/ha berpengaruh nyata meningkatkan serapan hara N bagian atas dari 1.93 mg/tanaman menjadi 3,93 mg/tanaman dan serapan hara N akar dari 1,25 mg/tanaman menjadi 2,16 mg/tanaman.

Abstract

Background: Limestone mine reclamation by Limited Liability Company (LLC)/Perseroan Terbatas (PT) Semen Tonasa is carried out periodically to restore land conditions sustainably. The reclamation was carried out through revegetation using endemic plants, namely the bitter plant (Vitex colossus R.), which grows significantly in the southern part of Sulawesi. This study aims to determine the erodibility of the soil in limestone mine reclamation land planted with bitti plants. Methods: The method used is the survey method by determining the location of soil samples using the purposive sampling method based on the reclamation age planted with bitti plants in 2019, 2015 and 2010 and determining the erodibility value using the formula according to Wischmerier and Smith (1978). The parameters used included soil texture, structure, organic matter, permeability, pH, and unit weight. Findings: The results of this study indicate that the erodibility of the soil in the limestone mine reclamation land planted with bitti plants is classified as high due to the high dust content, which is influenced by the parent material. The results of this study indicate that the erodibility value of the land reclamation in 2019 was classified as moderately low to moderately high, the land reclamation in 2015 was classified as moderate to moderately high, and the land reclamation in 2010 was classified as moderate to high. Conclusion: The factor affecting the erodibility of the soil in the reclamation area is the M value (percentage of very fine silt and sand). Novelty/Originality of this Study: This study's novelty lies in examining soil erodibility changes over different reclamation ages in a limestone mine using endemic bitti plants. This research highlights the unique relationship between reclamation age and soil properties, contributing valuable insights into effective land reclamation practices in tropical karst environments.

Abstract

Land degradation in upland sub-watersheds poses serious threats to environmental sustainability, agricultural productivity, and disaster risk. This study aims to evaluate the land condition of the Sileng Sub-Watershed in Borobudur District, Central Java, using an integrated approach based on four key indicators: erosion index, land cover index, land use suitability, and landslide susceptibility. Field surveys and spatial analyses were conducted in 18 land system units, with supporting data derived from Sentinel-2 imagery and regional spatial planning maps. The results show that 61.1% of land systems are in good condition, 33.3% in fairly good condition, and 5.6% in moderate condition. While erosion risk is generally low, two land systems show critical erosion and landslide susceptibility due to steep slopes and minimal vegetative cover. The high land use suitability (88.36%) indicates strong adherence to spatial planning regulations, while the land cover index (63.71%) suggests moderate vegetation density. Overall, the integrated land condition index highlights both areas of ecological resilience and zones requiring rehabilitation. These findings offer valuable insights for sustainable watershed management and policy formulation, particularly in tropical highland areas vulnerable to land degradation and climate impacts.
