Abstract

Planting corn is a local wisdom that is still practiced to maintain food availability in East Nusa Tenggara. In corn cultivation, the biggest challenge faced by farmers is the emergence of weeds around corn plants, which hinder their growth. Profiling the metabolites of weeds is an important initial step in studying the influence of allelochemical compounds that inhibit plant growth. This allows for appropriate weed control strategies. Chloris barbata is identified as a dominant weed in corn fields in East Nusa Tenggara. This study aims to profile the dominant weeds in corn fields in East Nusa Tenggara, specifically in Tua’tuka, Kupang Regency. The untargeted metabolit analysis of the three weed species revealed that Neophytadiene, accounting for 34.93% of Chloris barbata, is a compound strongly suspected to inhibit corn plant growth among the 36 compounds identified in the allelochemical study. The impact of allelochemicals from the other two weed species on corn growth needs further investigation due to limited information. Further studies are necessary to understand the effects of these allelochemicals on corn plant growth. Keywords: allelochemical; metabolites; weedsINTISARIMenanam jagung adalah suatu kearifan lokal yang masih terus dilakukan untuk menjaga ketersediaan pangan di Nusa Tenggara Timur. Dalam budidaya jagung, tantangan terbesar yang sering dihadapi oleh petani adalah munculnya gulma di sekitar tanaman jagung. Adanya gulma menyebabkan pertumbuhan tanaman jagung menjadi terhambat. Studi metabolit gulma merupakan langkah awal penting untuk mempelajari pengaruh senyawa alelokimia dalam menghambat pertumbuhan tanaman. Strategi pengendalian gulma dapat dilakukan dengan tepat. Chloris barbata merupakan salah satu jenis gulma yang telah diidentifikasi sebagai gulma dominan yang tumbuh pada pertanaman jagung di NTT. Penelitian ini bertujuan untuk melakukan analisis metabolit terhadap gulma dominan pada pertanaman jagung di NTT yang diambil dari Tua’tuka Kabupaten Kupang. Hasil analisis untargetted metabolit dari ketiga jenis gulma, menunjukkan bahwa Neophytadiene 34,93% dari Chloris barbata merupakan senyawa yang diduga kuat sebagai penghambat pada pertumbuhan tanaman jagung dari total 36 senyawa yang dihasilkan dari studi senyawa alelokimia. Dampak senyawa alelokimia dari dua jenis gulma lainnya terhadap pertumbuhan jagung masih perlu diteliti lebih lanjut karena keterbatasan informasi. Studi lanjutan diperlukan untuk memahami lebih dalam efek senyawa-senyawa alelokimia tersebut terhadap pertumbuhan tanaman jagung. Kata Kunci: alelokimia; gulma; metabolit

Abstract

Fulfillment of food can be done through the implementation of Sustainable Food Yards. KWT Sejati has difficulty providing food throughout the year. The yard owned is not productive because it has dry land biophysics with a dry climate. This condition is also a factor that influences people's food status (food insecurity). Management of dry land as agricultural land requires the adoption of technology. Verticulture technology can be used as an alternative to meet food needs in Karing. This activity aims to apply P2L to KWT Sejati through verticulture as a technology for cultivating vegetables on dry land. The method for implementing this activity is counseling and demonstration using a learning by doing system. The results of this activity provide many benefits to KWT Sejati, including: ease in managing dry land as agricultural land, being able to engineer planting media to improve soil quality, and producing higher production and income compared to using a raised bed system, and has the potential to overcome food insecurity conditions

Abstract

Many microbial populations are found in the rhizosphere, including in the soil layer that follows the plant root system. Rhizosphere soils contain more bacteria, fungi and actinomycetes than non-rhizosphere soils. One of the antibiotic producing bacteria has been isolated from the rhizosphere. The purpose of this study was to isolate and characterize the biochemistry of antibiotic producing bacteria and to evaluate their superiority in inhibiting other types of bacteria. Three microbial isolates were isolated from the rhizosphere of winged bean (K) and banana (P1 and P2) plants. All isolated isolates were tested for antagonism with E. coli, Bacillus, and Pseudomonas bacteria on Nutrient Agar (NA) media to determine antibiotic-producing bacteria. Furthermore, identification and characterization of colony morphology and a series of antagonism and pathogenicity tests were carried out. The three isolates had irregular colony forms (isolates K and P1) as well as oval shapes (isolate P2), flat surface, glossy texture, milky white or cream color, and irregular edges. The antagonism test showed that isolates P1, P2, and K could inhibit the growth of bacterial colonies E. coli, Bacillus, and Pseudomonas, respectively. In the pathogenicity test, the three microbial isolates did not show symptoms of necrosis in tobacco leaves after 2 days of observation.

Abstract

Manganese (Mn) mining in North Central Timor results in open land conditions that can change soil qualities. The aim of this study was to determine physical characteristics and chemical properties of the soil in the ex-manganese mining areas. The study was performed from June – September 2021. Soil characterization was carried out at selected locations where manganese mining was carried out both traditionally and using technology. The soil characteristics measured were texture, water content, bulk density, mass density, porosity, organic matter content, pH, cation exchange capacity (CEC), organic C, total nitrogen (N), total phosphorus (P), total potassium (K), and total Mn. The results showed that the physical characteristics of the soil on ex-Mn mining land from 5 villages in TTU, NTT are dominated by sand texture which results in low water content (3.39 - 9.46 %), soil porosity (14.96 - 59.31 %), and high bulk density (1.18 - 1.49 g cm-3). Characteristics of soil chemical properties showed low pH (< 7), organic matter (0.06 – 0.81%), organic C (0.03 – 0.22 %), total N contents (0.05 – 0.22%), and high total P (14.77 – 61.44 me 100 g-), K (66.66 – 71.18 me 100 g-), and Mn (18.802 – 24.055 ppm) contents. Land must be reclaimed Reclamation can be done by land management, top soil conservation, planting pioneer crops or cover crops.
