Abstract

Lahan merupakan lingkungan fisik yang terdiri atas iklim, tanah, air dan vegetasi serta benda diatasnya sepanjang ada pengaruhnya terhadap penggunaan lahan, termasuk  didalamnya hasil kegiatan manusia dimasa lalu dan sekarang. Potensi lahan tidur yang terdapat di Pesantren  Madinatul Quran relatif masih luas. Hal  ini bisa dimanfaatkan sebagai lahan produktif dengan budidaya berbagai jenis tanaman pertanian. Kegiatan pengabdian meliputi pembersihan lahan, penyiapan bedeng, penanaman, monitoring dan evaluasi.  Hasil kegiatan pengabdian diharakan dapat mengoptimalisasi  pemanfaatan  lahan tidur melalui upaya pemberdayaan masyarakat dengan mengoptimalkan  pemanfaatan pekarangan sebagai sumber pangan. Kata kunci: Budidaya, lahan tidur, optimalisasi lahan

Abstract

Post-mining land rehabilitation is an important strategy to mitigate climate change and conserve tropical ecosystems. Surface mining activities in East Kalimantan have caused ecological degradation and the release of carbon stored in vegetation and soils. Revegetation has been widely practiced as the main approach to restore ecosystem functions, including initial carbon accumulation by understory plants. This study aims to estimate the carbon stock of the understory on post-mining land that has undergone revegetation for one year at the PT Insani Baraperkasa site in Loa Janan, East Kalimantan. The method used was destructive sampling of understory biomass from 10 plots measuring 5 m x 5 m, each with subplots measuring 0.5 m x 0.5 m. Biomass samples were dried and converted to carbon. The results showed an average carbon stock of 1.26 tons/ha. These results suggest that understorey vegetation plays an important role in early stage carbon recovery on post-mining land. Understory carbon monitoring can be an effective early indicator to measure the success of ecosystem restoration. Keywords: revegetation, understorey, post-mining, carbon

Abstract

Kaliandra (Calliandra calothyrsus Meisn) is a plant capable of producing large amounts of biomass, potentially as a renewable energy source that supports the reduction of dependence on fossil fuels. The transition from fossil fuels to renewable energy is an urgent and long-term solution, as the use of fossil fuels as an energy source contributes to global warming and climate change.This study aims to evaluate the effect of compost fertilizer dosage and compost tea on the growth of height and diameter of kaliandra seedlings. Using a one-factor complete randomized design (CRD) method with treatment of compost fertilizer doses K0 (0 grams), K1 (60 grams), K2 (75 grams) and K3 (90 grams) and compost tea doses TK1 (0 ml), TK1 (50 ml), TK2 (75 ml) and TK3 (100 ml). Research results: 1. The treatment of compost doses and compost tea showed significant differences in the height growth of calliandra seedlings. 2. Compost fertilizer with a dose of 90 grams (K3) showed a better height growth rate than compost tea fertilizer with a dose of 100 ml (TK3), 75 ml (TK2), and 50 ml (TK1). 3. Compost tea fertilizer with doses of 50 ml (TK1) and 75 ml (TK2) showed a better height growth rate than compost fertilizer with doses of 60 grams (K1) and 75 grams (K2). 4. The compost fertilizer dose treatment showed a significant difference in the growth rate of Calandra seedling diameter, while the compost tea dose treatment did not show a significant difference. 5. Compost fertilizer with doses of 75 grams (K2) and 90 grams (K3) showed better diameter growth than compost tea fertilizer with doses of 75 ml (TK2) and 100 ml (TK3). 6.  The optimal dosage recommendation in this study is 90 grams of compost fertilizer and 75 ml of compost tea.

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.
