Abstract

Penelitian ini dilatar belakangi banyaknya limbah ampas tahu yang tidak dimanfaatkan oleh masyarakat hannya sebagai limbah yang terbuang, dengan adanya penelitian ini mencoba menggunakan bioaktivator mikroorganisme nasi basi sebagai bahan fermentasi. Tujuan penelitian ini adalah: 1).Mengamati sifat fisik pembuatan pupuk organik padat (Kompos). 2).Menganalisa kandungan unsur hara pupuk organik padat N, P, K, C-organik, C/N Rasio dan pH. 3).Membandingkan hasil unsur hara Standar Mutu Pupuk Organik padat Peraturan Menteri Pertanian syarat kompos nomor 261/Permentan/SR.310/4/2019SNI 2019. 4).Penghitungan lama waktu jadinya pupuk organik padat dari limbah ampas tahu. Dari hasil penelitian ini Sifat fisik pupuk organik padat setelah matang adalah: suhu mencapai 26◦C, terjadi perubahan warna yang awalnya putih berubah menjadi coklat tua serta tidak beraroma menyerupai warna tanah. Hasil analisis kandungan unsur hara makro untuk perlakuan T1 adalah sebesar N 2.123 %, C-Organik 41.768, C/N rasio 19.675 % pH.5.69 dan Unsur hara perlakuan T2 yaitu C-Organik 44.304, C/N rasio 23.344% dan pH.5.78, sudah memenuhi Standar Mutu Pupuk Organik padat Peraturan Menteri Pertanian syarat kompos nomor 261/Permentan/SR.310/4/2019, sedangkan unsur hara perlakuan T1 yaitu P 0.034 %, K 0.033 %, dan unsur hara perlakuan T2 yaitu N 1.898 %, P 0.029 %, K 0.019 % belum memenuhi standar Permentan pupuk kompos padat nomor 261/Permentan/SR.310/4/2019. Lama waktu proses pembuatan pupuk organik padat limbah ampas tahu T2 matang di hari ke-15 lebih cepat dari T1 yang matang di hari ke-18.

Abstract

The knowledge of farming methods and various traditional agricultural tools owned by the ancestors of the people of East Kalimantan has been passed down to their descendants, remaining simple and used by a group of people from generation to generation, forming part of their technological system, according to their cultural conceptions. However, the current agricultural transformation in Samarinda shows a clear shift from traditional to modern farming systems, evident in the application of modern technology in agricultural activities. This study examines the transformation process, its driving factors, socio-economic impacts, and challenges and development strategies. Data were collected through literature review and interviews with local farmers. The results indicate that modern agriculture increases productivity and work efficiency, attracts younger generations, and supports food security in the region. However, limited land and access to technology are key challenges. The study concludes that agricultural modernization in Samarinda must be supported by inclusive policies that integrate technology, strengthen farmer institutions, and empower young people.

Abstract

Black orchids are a renowned germplasm source in East Kalimantan. However, their habitat is becoming increasingly scarce due to slow cultivation, necessitating rapid and precise propagation methods, such as tissue culture. Subculture is a key component of tissue culture. The purpose of this study was to determine the growth response of black orchid on MS growing media with the addition of foliar fertilizer and natural extracts.  This research was conducted at the Tissue Culture Laboratory, Faculty of Mathematics and Natural Sciences, Mulawarman University. The study period was three months, from March to June 2025. This study used a non-factorial Completely Randomized Design (CRD). Three treatment levels, each level consisting of eight replications: S0 (control), S1 (MS Media + leaf fertilizer), S2 (MS Media + natural extract). Data were analyzed for diversity using Analysis of Variance (ANOVA) with an α level of 5% and then Duncan's Multiple Range Test (DMRT) with an α level of 5%. The results showed that all three treatments significantly affected all observed variables. The addition of leaf fertilizer to MS media produced the best response in terms of shoot emergence time and shoot number. The addition of natural extract to MS media produced the best response in terms of leaf number.
