Abstract

Penelitian ini dilakukan untuk mempelajari pengaruh jarak tanam dan dosis nitrogen (N) terhadap pertumbuhan dan hasil padi ketan grendel (Oryza sativa L. var glutinosa). Penelitian dilaksanakan di Desa Jatisari, Karawang, Jawa Barat yang berada pada ketinggian 25.6 m dpl pada Januari-Juni 2022. Penelitian menggunakan rancangan split plot dengan dua faktor yaitu jarak tanam sebagai petak utama (20 cm x 20 cm, 25 cm x 25 cm, 30 cm x 30 cm, dan 40 cm x 40 cm) dan dosis N sebagai anak petak (0, 45, 90, 135, dan 180 kg N ha-1). Kombinasi perlakuan diulang sebanyak 3 kali. Hasil penelitian menunjukkan bahwa jarak tanam 40 cm x 40 cm dan dosis N 180 kg N ha-1 merupakan kombinasi terbaik karena dapat meningkatkan tinggi tanaman, jumlah anakan, warna daun, jumlah anakan produktif, bobot kering sampel, bobot gabah hampa, jumlah bulir per malai, dan hasil ubinan (GKP) yang lebih tinggi dibandingkan dengan perlakuan lain. Dengan demikian, jarak tanam dan dosis tersebut direkomendasikan untuk dikaji lebih lanjut dalam rangka mendukung produktivitas padi ketan grendel. Kata kunci: dosis rekomendasi, jarak tanam, komponen hasil, pemupukan nitrogen

Abstract

Ubi kayu atau singkong merupakan komoditas industri dan komponen penting pada ketahanan pangan di Indonesia, tetapi informasi jejak karbon dari kegiatan budidaya masih terbatas. Jejak karbon adalah salah satu pendekatan untuk memahami sumber emisi gas rumah kaca (GRK) yang berguna untuk mitigasi pemanasan global. Penelitian bertujuan melakukan asesmen jejak karbon budidaya ubi kayu pada berbagai taraf pupuk NPK dan karbon organik tanah (C-org). Penelitian dilakukan pada September 2022 hingga Mei 2023 di Kebun Percobaan IPB Jonggol. Data emisi diestimasi menggunakan skenario tier 1. Budidaya ubi kayu memiliki jejak karbon 2,511.2-10,641.4 kg CO2-eq ha-1 tergantung dosis NPK dan C-org. Budidaya mengemisikan karbon rata-rata 6,455.5 kg CO2-eq ha-1 dengan emisi langsung 4,532.3 kg CO2-eq ha-1dan tidak langsung sebesar 1,923.2 kg CO2-eq ha-1. Input NPK dan pupuk kandang menyumbang emisi langsung terbesar yakni berturut-turut 36.99% dan 54.96%. Pada waktu yang bersamaan, budidaya menskuestrasi karbon 27,445.1- 61,684.2 kg CO2-eq ha-1 (rata-rata 51,032.4 kg CO2-eq ha-1) sehingga budidaya memiliki neraca karbon positif yang berarti mengurangi GRK, yakni sebesar 24,933.9-54,493.1 kg CO2-eq ha-1 (rata-rata 44,577.0 kg CO2-eq ha-1). Berdasarkan regresi, tingkat C-org 4.8% dan dosis NPK (15-15-15) 440.7 kg ha-1 memberikan pengurangan (offsets) emisi GRK maksimum. Upaya mencapai budidaya ubi kayu rendah emisi diprioritaskan melalui pengurangan input pupuk misalnya dengan mengembalikan limbah biomasa budidaya. Kata kunci: emisi karbon, emisi GRK, ketahanan pangan, rendah emisi, singkong

Abstract

Taro (Colocasia esculenta) as a leading commodity in Bogor Regency faces challenges in technology adoption, price fluctuations, and post-harvest infrastructure, so a participatory approach such as a Focus Group Discussion (FGD) is needed to formulate innovative and applicable solutions. This FGD activity aims to identify challenges, opportunities, and strategic solutions for taro farmers in Bogor Regency. Bogor taro is one of the leading commodities with high economic potential, both for the local market and for export. However, farmers face various challenges, such as low adoption of modern technology, price fluctuations, limited access to capital, weak farmer group organizations, and pest and disease attacks. The FGD was carried out in several stages, namely preparation, group discussion, data analysis, and follow-up. The FGD involved 29 participants consisting of taro farmers with diverse profiles based on age, education, farming experience, and land area. The results of the FGD showed several opportunities, such as the development of taro-based processed products, organic farming practices, and export potential. The proposed strategic solutions included technical training to increase productivity, diversification of processed products, government policy support, and strengthening the role of women and youth in farming. The results of this activity are expected to serve as a guide for stakeholders to promote the sustainability and development of the taro farming sector in Bogor Regency.

Abstract

Penetapan rekomendasi dosis kalium (K) berdasarkan uji tanah untuk tanaman tomat pada tanah Andisol belum banyak dikaji di Indonesia. Penelitian ini bertujuan untuk menentukan rekomendasi pemupukan kalium (K) pada tanaman tomat di tanah Andisol berdasarkan uji tanah. Tahapan penelitian meliputi penetapan status hara K tanah, uji korelasi K di rumah kaca, uji kalibrasi K di lapangan, serta penentuan rekomendasi pemupukan K. Penetapan status hara K tanah dilakukan dengan enam tingkat ketersediaan K dari sangat rendah hingga sangat tinggi (0, ¼X, ½X, ¾X, dan X), di mana X merupakan nilai tertinggi serapan hara K tanah sebesar 413.4 kg K ha-1. Penelitian ini menggunakan pendekatan lokasi tunggal dengan rancangan acak kelompok sebanyak lima ulangan. Hara K diinkubasi selama empat bulan, kemudian dilakukan pengambilan sampel tanah untuk analisis kandungan K. Uji korelasi dilakukan di rumah kaca dengan rancangan acak lengkap lima ulangan, sedangkan uji kalibrasi di lapangan menggunakan rancangan petak terbagi dengan rancangan acak kelompok lima ulangan. Hasil penelitian menunjukkan bahwa metode ekstraksi K terbaik untuk tanah Andisol pada tanaman tomat adalah NH₄OAc. Batas ketersediaan hara K-NH₄OAc ditetapkan sebagai sangat rendah (<84 ppm K), rendah (84–<121 ppm K), sedang (121–<202 ppm K), serta tinggi dan sangat tinggi (>202 ppm K). Kebutuhan K untuk hasil maksimum tomat pada tingkat kesuburan sangat rendah, rendah, dan sedang berturut-turut adalah 442, 363, dan 298 kg K₂O ha-1, sedangkan untuk hasil optimum berturut-turut sebesar 426, 348, dan 283 kg K₂O ha-1.  Kata kunci: hara K, NH4OAc, uji kalibrasi, uji korelasi

Abstract

Amorphophallus variabilis Blume, a member of Araceae, is a fleshy perennial tuber crop endemic in Java Island, Indonesia. The plant produces white edible corm; and it was used as food during famine time before 1960s. Rapid ecological changes and land fragmentations in Java in recent times threaten populations of A. variabilis. Here, compound microsatellite markers were developed in order to develop conservation strategies in the populations. Twelve primers pairs produced high polymorphism ranging from 5 to 22 alleles per locus. The observed and expected heterozygosities ranged from 0.191 to 0.851 and 0.380 to 0.943, respectively. This high allelic diversity indicates that these markers are suitable for the study on population genetic structure. Cross-amplification on related and non-related species was performed. Application of the markers on populations from Dramaga Conservation Forest revealed high allelic richness, high diversity within and among populations. Genetic distance among populations increased with an increase of geographic distance. Present study suggested that, it is important to study population of A. variabilis in Java in order to understand the population genetic structure and develop effective in situ conservation programs.

Abstract

Ultisols are characterized by low pH, low alkaline saturation, low cation exchange capacity, and high levels of soluble Al and Fe. Compost is usually applied to increase soil fertility, but its effect is only temporary in tropical conditions because organic matter decomposes quickly. Biochar and fly ash-enriched compost have been proposed as a synergistic approach to improve the chemical properties of Ultisols. This study evaluated the effect of compost enriched with biochar and fly ash on soil chemical dynamics over 16 months in pineapple plantations in Lampung, using a randomized block design with three treatments: compost enriched at the initial stage, compost alone as a control, and compost enriched at the end of composting. The results showed that biochar and fly ash increased soil pH during the initial phase by supplying alkaline cations. Fluctuations occurred during the intermediate stage due to the decomposition of organic matter and nitrogen transformation: organic C and total N increase, influenced by microbial activity and environmental conditions. Phosphorus followed a mineralization-immobilization-remobilization pattern, with late-stage enrichment producing P. Potassium, calcium, and magnesium initially increased but later decreased, likely due to leaching. Early-stage enrichment provided a more stable release of alkaline cations. Fe, Mn, Cu, and Zn show fluctuations in the enriched treatment. The application of biochar and fly ash-enriched compost synergistically with early-stage enrichment effectively enhances the chemical properties of Ultisol.

Abstract

Indonesia has significant potential for food diversification through the development of sago as an alternative carbohydrate source. This study aims to analyze the processing methods, morphological characteristics, chemical properties, and heavy metal content of local sago in Bangka and Bangka Tengah Regencies. The research was conducted across six villages from November 2023 to March 2024, with chemical and heavy metal testing performed in accredited laboratories. The results indicate that modern processing methods produce high quality starch with a starch content ranging from 79.06% to 83.73% and heavy metal levels such as tin (Sn), lead (Pb), and cadmium (Cd) below the established safety limits, making it safe for consumption. Morphologically, habitat differences influence the physical characteristics of sago, such as trunk height, bark thickness, and leaf area, which affect starch productivity. The study also identifies that environmental factors, including nutrient availability and soil moisture levels, influence the chemical composition of sago. This research provides a scientific foundation for the integrated management of sago, supporting national food diversification efforts and opening opportunities for the development of sago based products that meet national quality standards (SNI) with an environmentally friendly approach. These findings are relevant for stakeholders in optimizing sago's potential as a strategic commodity contributing to national food security. Keywords: Food diversification, Heavy metal, Sago, Starch content, Sustainable agriculture.

Abstract

Coromandel, or Chinese violet (Asystasia gangetica), is an invasive weed on many plantations in Indonesia, especially oil palm plantations. The A. gangetica is suspected to produce allelopathic compounds. However, the evaluation of the effect of A. gangetica on plant growth is still rare. The research objective was to evaluate the effect of allelopathic compounds of A. gangetica on the growth and production of sweet corn as a test plant. An experiment with a randomized complete block design and four replications was conducted from March to September 2022 at the Agribusiness and Technology Farm IPB. The treatment was the A. gangetica population consisted of 0 (control), 1, 2, 4, 8, and 16 individuals per pot. A. gangetica were initially planted from seeds, and the stems were slashed 5 cm above the soil surface two months after planting. One week after cutting, sweet corn seeds were planted and maintained until harvest 72 days after planting. The results showed that the allelopathic effect of A. gangetica was evident in growth of sweet corn plant. Increasing number of A. gangetica per pot increased the allelopathic effect. The most significant effect was from 16 populations per pot, which significantly reduced the growth of sweet corn height, stem diameter, leaf size (length and width), leaf number, and color. The particular population per pot also decreased sweet corn yield, i.e., weight per cob with and without husk, and cob diameter by 18.95%, 22.0%, and 19.37%, respectively. The level of sweetness decreased by 31.24% after sweet corn was planted in the remnant of 16 individuals A. gangetica per pot. Nevertheless, A. gangetica did not significantly affect leaf area index, cob length, and sweet corn biomass, including shoot and root dry weight at harvest. It would be interesting to evaluate the effect of A. gangetica in the field. Keywords: allelopathy; Brix; indole-3-carboxaldehyde; secondary metabolites; weeds
