Abstract

Usahatani padi sawah merupakan hal yang penting dalam menjamin ketahanan pangan dan pendapatan petani lokal. Seiring dengan semakin berkembangnya teknologi dan metode dalam meningkatkan produktivitas dan produksi tanaman pangan, hampir semua petani menggunakan pestisida berbahan kimia dengan berbagai dosis dan tindakan, namun tidak semua memahami aturan dan dosis yang sesuai untuk setiap jenis tanaman pangan khususnya tanaman padi sawah. Pestisida dalam kaitannya dengan lingkungan adalah salah satu elemen yang dapat mencemari tanah untuk waktu yang lama baik biotik dan abiotik. Makalah ini mengulas dan mensintesis 1025 jurnal dan disaring kembali berdasarkan negara ASEAN diperoleh 52 jurnal, dan disaring kembali berdasarkan komoditi padi sawah yang tercemar pestisida diperoleh 9 jurnal dari database Scopus yang diterbitkan antara tahun 2014 – 2022. Artikel jurnal yang diulas dikategorikan ke dalam tema pencemaran pestisida dan logam berat pada tanaman padi sawah pada beberapa negara yang mencakup ke dalam ASEAN (Indonesia, Thailand, Malaysia, Vietnam). Pengaruh pencemaran pestisida ini sudah banyak dilaporkan dalam beberapa kasus pencemaran dalam skala ringan sampai berat. Pencemaran ini dapat berpengaruh pada sifat fisik dan kimia tanah, populasi mikrob total, emisi GRK, bahkan tidak hanya berpengaruh pada kesehatan lahan namun sampai berpengaruh terhadap kesehatan petani dan hewan di sekitar lahan. Topik dominan yang kami temukan dalam literatur adalah pencemaran pestisida dan logam berat dengan metode analisis kromatografi gas (GC) yang mencakup hanya pada tanaman padi sawah. Kontribusi dari makalah ini adalah menghasilkan kerangka kerja komprehensif dan informasi yang perlu dilakukan dalam mengidentifikasi dan memberikan pengetahuan awal mengenai pencemaran tanah dan lingkungan akibat penggunaan pestisida.

Abstract

The extraction method plays a crucial role in obtaining high-quality DNA samples, which is indispensable for various molecular biology techniques and analyses, enabling a deeper comprehension of genetic information and biological processes. The objectives of the study were: a) to optimize the chloroplast DNA extraction protocol by comparing modified CTAB methods and GeneAid for both leaf and wood samples of Shorea leprosula, a major commercial timber species, and b) to identify a suitable cpDNA region that exhibits variability and universality across taxa. Total DNA was analyzed by gel electrophoresis followed by Sanger sequencing to determine the amplification success. The results revealed that trnL intron, trnL-trnF, and trnG yielded readable sequences of the expected length (maximum 586 bp, 480 bp, and 908 bp, respectively), while the rps 16 intron failed to assemble a contig. The petL-psbE region provided long readability for reverse sequences (769 bp) but not for the forward sequence (195 bp). Higher successful DNA extraction was achieved from the leaves compared to the woods. The lower sequencing quality may be attributed to suboptimal primer design, the structural features of the regions resulting from extensive repetitive sequences, and the suboptimal condition of the extraction method in eliminating wood chemical compounds.

Abstract

Eucalyptus plants, renowned for their economic and environmental significance, are cultivated globally. Despite their value, these plants are vulnerable to pest and disease attacks, impacting productivity and quality. Accurate and timely monitoring is required to control pests and diseases in eucalyptus plants. The conventional method of human-based direct observation for monitoring pests and diseases in eucalyptus plants is fraught with weaknesses. Therefore, efforts are needed to enhance the effectiveness and efficiency of monitoring pests and diseases in eucalyptus plants through artificial intelligence or AI technology. AI is used to automatically detect and classify pests and diseases in eucalyptus plants using machine learning or deep learning algorithms and image processing. This study aims to provide a comprehensive review of the use of AI for detecting pests and diseases in eucalyptus plants using the Systematic Literature Review (SLR) method. Through this approach, this study identifies, evaluates, and analyzes relevant literature on the research topic from various digital sources. This study also provides an overview of the latest developments, methods used, and results achieved, as well as challenges and opportunities in the field of AI research for detecting pests and diseases in eucalyptus plants.

Abstract

Rattan is a forest plant that has high economic and ecological value. This species grows in various habitats because of its good adaptability. Gunung Walat education forest (GWEF) is an ex-situ conservation location owned by IPB University and rattan conservation potential. In 2005 rattan were planted in this area from some material source in Indonesia, but the information regarding its identity was still limited. Therefore, this study aims to identify rattan in GWEF using barcode methods. Four barcoding those were rbcL, matk K, psbA-trnH, and ITS 1 was used for this purpose. Molecular analysis was conducted through DNA extraction using the CTAB method, DNA quality and quantity observation using electrophoresis and Polymerase Chain Reaction (PCR) amplification. The result of this research showed that DNA barcodes show a different

Abstract

The 0.6% contribution of the forestry sector to GDP is considered very low despite 64.1% of Indonesia's land area being allocated as forests. Most of the 64.8% production forest allocated is not yet optimized for strengthening national food security, in which Indonesia is ranked 65th in the world. Therefore, an innovative forest management system is needed to synergize timber and non-timber production. This paper presents a multi-business forestry (Mb-F) implementation strategy analyzed through a dynamic system-based multi-criterion decision-making tool named Super Model Mb-F (SM Mb-F). SM Mb-F is built based on a causal loop diagram (CLD), which describes the dynamic relationship between land typology suitability and decisions related to the type of business, commodities, land use area, workload, and financing for many variables relating to 5M business principles and sustainability. Results showed that CLD formulated in 280 sub-models in a total of 4,764 decision variables with an error deviation of 6.4%. The SM Mb-F simulation on two sample concession units produces a projected increase in wood supply, employment, and state revenue, plus the provision of new functions such as food, NTFP, and environmental services. These benefits are obtained by business feasibility. Assuming that gradually until 2030, the Mb-F can be implemented in 32% of Indonesia's production forests, then by 2045, it is projected that there will be an increase in wood production by 296.8%, state revenue by 654.3%, and labor absorption by 985.7%, as well as adding food production up to 19.36 M tons. This is because the land use efficiency of the current operation of forest concessions following the Annual Allowable Cut (AAC) under the selective cutting and replanting system in Indonesia (TPTI) is only about 3% of the total area of forest concession. Assuming the cutting cycle is 35 years, timber could be extracted in 1/35 of the total forest concession area. Implementing Mb-F will significantly improve the land use efficiency from about 3% to 90%.  The Mb-F will also restrain the rate of decline in carbon stocks, which is deeper if governance is still under the BAU scenario. This research suggests further global research, emphasizing the importance of innovative models for sustainable forestry governance and food security worldwide.

Abstract

IPB University telah berkomitmen untuk menjadi bagian dari Nature Positive Universities Network, yang sejalan dengan komitmen IPB sebagai Green Campus (Kampus Hijau), Kampus Biodiversitas dan komitmen IPB Netral Karbon 2030, dengan melaksanakan empat elemen Nature Positive yakni: (1) penilaian dasar keanekaragaman hayati, (2) penentuan target alam yang spesifik; (3) pengayaan dan penanaman; dan (4) pelaporan data atau status keanekaragaman hayati secara tahunan. Namun tantangan utamanya adalah bagaimana merubah fixed mindset ke arah Nature Positive, selain merubah paradigma menjadi Kampus Hijau. Tentunya, diperlukan visi yang kuat, dukungan finansial, tata kelola yang baik serta perilaku ramah lingkungan seluruh sivitas akademika. Beberapa langkah yang dapat dilakukan IPB University menuju Nature Positive Universities antara lain penentuan lokasi penilaian keanekaragaman hayati kampus IPB untuk Nature Positive Universities project, penilaian dasar keanekaragaman flora dan fauna sebagai baseline status keanekaragaman hayati di kampus IPB, deliniasi Taman Hutan Kampus, dan pembuatan permanent plot Taman Hutan Kampus untuk monitoring keanekaragaman hayati, pengayaan tanaman, penilaian keanekaragaman hayati secara berkala, serta pembangunan basis data dan sistem informasi keanekaragaman hayati.

Abstract

The selection of tree species suitable for restoration in diverse site conditions is still a challenge. Therefore, this study aimed to analyze the phenotypic and genetic characteristics of Dryobalanops aromatica seedlings growing in mineral soil media and peat media. Phenotypic characteristics were evaluated by analyzing the growth performance, leaf morphological characteristics, leaf color, and chlorophyll content, while genetic characteristics were evaluated by using microsatellite markers. The study revealed that seedlings planted in peat media exhibited greater height and shoot length growth, although the difference was not statistically significant compared to those in mineral soil media. However, seedlings in mineral soil media displayed a significantly higher survival rate than those in peat media. Peat-grown seedlings had higher chlorophyll content in their leaves, while mineral soil-grown seedlings displayed a lighter green leaf color based on digital analysis. Genetic analysis indicated a high genetic diversity of overall D. aromatica seedlings (He = 0.635) and unclear genetic structure between the two media. Overall, these findings demonstrate the successful adaptation of D. aromatica seedlings to peat media, positioning them as a promising choice for peatland restoration.

Abstract

Gyrinops versteegii and Aquilaria malaccensis are two important species of the Aquilarieae tribe. The main problem of this tribe is the challenge of species identification that is strongly dependent on the presence of flowers and fruit, which are not always available. The availability of whole genome information is expected to address the problems of species identification. This research aims to construct and compare the chloroplast and mitochondrial genomes of G. versteegii and A. malaccensis from short-read data using the NOVOplasty and GetOrganelle assembler. The chloroplast genome assembly revealed a full-length quadripartite circular structure with sizes of 174.814 bp (G. versteegii) and 174.821–174.822 bp (A. malaccensis), with highly conserved gene and organization. Meanwhile, the mitochondrial genome is multipartite with a size of 400.012 bp (G. versteegii) and 400.000 bp (A. malaccensis), with highly variable genes and organization due to the presence of gene cluster repeats. The LSC/IR/SCC region borders and phylogenetic analysis in chloroplasts indicate variations between the genomes of these two species. The investigation of nucleotide diversity in the chloroplast genome revealed that the trnL-rpl32 region had the highest nucleotide diversity (Pi = 0.03). This information will be useful in the future for a variety of downstream analyses.
