“…Aktivitas mikrobiologi dan populasi tanah akan meningkat akibat penambahan bahan organik, secara khusus terkait dengan mineralisasi dan pemecahan zat organik. Beberapa mikroorganisme yang berperan dalam pembusukan bahan alami adalah makhluk organik, actinomycetes, dan organisme (Harahap et al, 2020).…”

The higher the productivity of the Mamasa coffee plant, the greater the waste produced and if it is not processed it will cause environmental problems. This research aims to produce and characterize the macro nutrient value in compost from Mamasa coffee waste using the microorganism bioactivator EM 4. This research was carried out by mixing coffee waste with EM-4, water and sugar in certain proportions. The composting process lasts for four weeks, with observations every week to trigger physical and chemical changes in the compost produced. The research results showed that the compost produced had good physical characteristics, namely black in color, not lumpy and odorless. Determination of macro nutrient levels in the organic material of Mamasa coffee waste before and after fermentation into compost showed a significant increase in the macro nutrients it contains, namely total organic C 25.59%; organic matter was 43.91%, Nitrogen was 2.53%, P2O5 was 1.95%, K2O was 1.68%, C/N ratio was 9.48 and water content was 24.34%. Thus, Mamasa coffee waste can be processed into high quality compost using EM-4, thereby providing a sustainable solution for managing organic waste and increasing soil fertility.

“…Hasil ini didukung dengan penilitian (Banamtuan, 2020;Ikbal et al, 2016) yang menyatakan bahwa kandungan C-organik tanah dapat meningkat setelah penambahan kompos dan bahan humat serta (Arifiati & Nuraini, 2017) mengemukakan bahwa peningkatan C-organik tanah akibat adanya pelepasan Corganik dari kompos. Hasil penelitian (Harahap et al, 2020) juga menyatakan bahwa pemberian kompos sampah kota 4,5 -6 % dapat meningkatkan kandungan C-Organik pada tanah terdegradasi.…”

asalah utama yang dihadapi dalam pemanfaatan tanah Podsolik Merah Kuning (PMK) adalah rendahnya kandungan hara serta buruknya sifat fisika dan kimia tanahanya. Sifat kimia tanah PMK yang bermasalah diantaranya yaitu pH tanah masam, kandungan C-organik rendah, P tersedia rendah, KTK dan basa-basa dapat dipertukarkan (K, Ca, Mg, Na) yang rendah. Penelitian ini bertujuan untuk memperbaiki beberapa sifat kimia tanah PMK dengan aplikasi kompos sebagai bahan amelioran serta pengaruhnya terhadap pertumbuhan dan hasil tanaman caisim (Brassica juncea L.) sebagai tanaman indikator. Penelitian menggunakan Rancangan Acak Lengkap (RAL) faktor tunggal dengan 5 perlakuan yang terdiri dari tanpa kompos (K0), kompos 5 ton/ha (K5), kompos 10 ton/ha (K10), kompos 15 ton/ha (K15) dan kompos 20 ton/ha (K20). Hasil penelitian menunjukkan bahwa aplikasi kompos dengan dosis 20 ton/ha (K20) mampu memperbaiki pH, C-Organik, KTK, P-tersedia dan Cadd, Mgdd, Kdd dan Nadd tanah PMK serta meningkatkan produksi tanaman caisim.

“…Pupuk organik berperan penting dalam meningkatkan pH tanah. Pupuk organik yang ditambahkan ke tanah akan terdekomposisi lanjut atau termineralisasi melepaskan mineral-mineral berupa kation-kation basa (Ca, Mg, Na, K) yang menyebabkan konsentrasi ion OH-meningkat sehingga mengakibatkan pH naik (Yuniarti et al, 2020).Beberapa pupuk organik yang dapatdigunakan untukmeningkatkan kesesuaian lahan sawah terhadap tanaman padi diantaranya adalah jerami padi (Asmin dan Karimuna, 2014),pupuk kandang (Padmanabhaet al, 2014) dan kompos (Harahap et al, 2020).Peningkatan kesesuaian lahan tersebut diharapkan dapat meningkatkan hasil padi. Hasil penelitian Kaya et al (2014) menunjukkan bahwa pupuk kandang dengan dosis 3 ton/ha menghasilkan produktivitas padi tertinggi yaitu sebesar 4,51 ton/ha.…”

The low productivity of rice in Seluma Selatan District is caused by fertilization actions based on general recommendations and not based on site-specific recommendations. In fact, fertilization should be based on soil nutrient status, especially N, P and K. This study aims to determine the nutrient status and evaluate the suitability class of lowland rice in Seluma Selatan District, Seluma Regency. This study used survey methods, soil sampling, and laboratory analysis, then matched it with the soil fertility level classification system and land suitability classification. The results showed that the nutrient status of paddy fields in Seluma Selatan sub-district in low-medium rice fields was categorized. It is characterized by an acidic pH value and low P2O5 in providing nutrients for lowland rice plants. Evaluation of land suitability in Seluma Selatan sub-district shows that the land suitability classes are S2 and S3. The results of the evaluation of the most suitable land suitability for land unit 2 (Au.1.1.1) were quite suitable for S2n with available nutrient limiting factors at the P2O5 level and marginally suitable for S3n on land unit 4 (Hab.1.1.1) with available nutrient limiting factors at P2O5 and K2O levels. Efforts to improve the suitability class S2 (fairly suitable) can be increased to S1 class (very suitable) and the S3 land suitability class (marginally appropriate) can be increased to S2 (quite suitable) .
