Abstract

The geographical condition of Indonesia's agriculture in the tropics supports agricultural business throughout the year through agricultural intensification. Agricultural intensification brings benefits to agricultural productivity, but also causes farmers to be dependent on pesticides and inorganic fertilizers in excess, causing long-term degradation of agricultural land productivity. Susstainable Agriculture is an approach to increase agricultural productivity while still being friendly to the agricultural ecosystem. Sustainable agriculture can be achieved through the preservation of agricultural resources, one of which is the use of beneficial microorganisms. Stre ptomyces sp. and Trichoderma sp. is a multi-role microorganism as a supporter of plant growth, biological agent in pest control, and helps increase soil fertility. The use of these microorganisms has good prospects for sustainable modern agriculture in order to achieve food security but also has obstacles that need to be overcome through further research.

Abstract

Limbah kotoran ternak selaku produk samping budidaya peternakan mempunyai dampak negatif bagi lingkungan berupa bau, cemaran lingkungan, dan sumber penyakit. Biokonversi secara anaerob dapat mengonversi limbah kotoran ternak menghasilkan digestat akhir berbentuk slurry yang kaya kandungan hara sebagai pupuk organik. Sejauh ini, studi tentang dinamika sifat fisik dan kimia digestat dari berbagai jenis kotoran ternak masih jarang dilakukan. Penelitian ini bertujuan untuk mengkaji pengaruh tiga jenis kotoran ternak (kambing, ayam, dan sapi) terhadap sifat fisik dan kimia digestat. Percobaan dirancang menggunakan rancangan acak lengkap (RAL) sederhana dengan perlakuan tiga jenis kotoran dengan tiga kali ulangan. Digestat dibuat dengan bahan kotoran ternak, urin sapi, aktivator EM4, dan daun lamtoro yang diinkubasikan secara anaerob selama 14 hari. Parameter yang diamati meliputi aroma, warna, kekentalan, buih, pH, dan suhu yang diamati 2 hari sekali hingga 14 hari setelah inkubasi (HSI). Hasil menunjukkan bahwa digestat kambing dan sapi memiliki kesamaan pola dinamika sifat fisik dan kimia. Karakter aroma, warna, kekentalan, dan buih digestat sapi dan kambing cenderung tidak berubah selama masa inkubasi dibandingkan digestat ayam. pH ketiga digestat memiliki kecenderungan untuk turun di awal inkubasi dan naik di pertengahan hingga akhir inkubasi mendekati pH 7,0. Kenaikan suhu digestat ayam lebih tinggi mencapai 40 oC sementara kenaikan suhu digestat kambing dan sapi lebih rendah. Secara keseluruan, digestat kambing dan sapi cenderung lebih sulit didegradasi dan membutuhkan waktu lebih lama untuk terdekomposisi sempurna dibandingkan digestat ayam yang diduga dikarenakan perbedaan karakter kotoran yang dipengaruhi komposisi pakan, mikroba usus, dan struktur pencerbaan ternak tersebut.

Abstract

Sugar cane (Saccharum officinarum L.) is the main ingredient in sugar production. Sugarcane is widely cultivated in warm and tropical areas and is widely used as a sweetener because it contains a lot of fructose and glucose. National sugar production shows a decline, the majority of which is caused by pathogens, especially the fungus Bipolaris sp. capable of producing up to 85% damage per Ha if no control is applied. Biological control using Trichoderma spp. can control this pathogen and is able to promote sugarcane growth. The purpose of this study was to determine the effectiveness of Trichoderma spp. in controlling Bipolaris sp. in vitro. The results showed isolates TD1, TD2, TD3 were able to inhibit Bipolaris sp. antagonistically and volatilely, the antagonist test showed a result of 86% (TD1) while the volatile test of 65% (TD2). Conclusion Trichoderma spp. can inhibit the growth of Bipolaris sp. on an in vitro scale. Keywords: BCA, Bipolaris sp. Trichoderma spp. ABSTRAK Tebu (Saccharum officinarum L.) merupakan bahan utama dalam pembuatan gula. Tebu banyak dibudidayakan didaerah hangat dan tropikal dan banyak digunakan sebagai pemanis dikarenakan mengandung banyak fruktosa dan glukosa. Produksi gula nasional menunjukan adanya penurunan yang mayoritas disebabkan oleh patogen terutama jamur Bipolaris sp. yang mampu menghasilkan kerusakan hingga 85% per Ha jika tidak diberlakukan pengendalian. Pengendalian biologis menggunakan Trichoderma spp. dapat mengendalikan patogen ini dan mampu mendorong pertumbuhan tebu. Tujuan penelitian ini ialah untuk mengetahui efektivitas Trichoderma spp. dalam mengendalikan Bipolaris sp. secara In vitro. Hasil menunjukkan isolat TD1, TD2, TD3 mampu menghambat Bipolaris sp. secara antagonis dan volatile, uji antagonis memperlihatkan TD1 memiliki hasil 86% sementara uji volatile TD2 memiliki hasil 65%. Kesimpulan Trichoderma spp. dapat menghambat pertumbuhan Bipolaris sp. dalam skala In vitro. Kata kunci: APH, Bipolaris sp. Trichoderma spp.
