Abstract

The relocation of the capital city of the Republic of Indonesia from Jakarta to the Nusantara Capital City (IKN) is a critical topic for the public, as it is designated as a strategic national project. However, the lack of public participation may generate community concerns regarding its potential impact. This research involved extracting public opinion from YouTube comments to identify the community’s desires, thereby providing policymakers with valuable information. Clustering the comments using the K-Means method successfully extracted public opinions from 27,063 comment data points. Among the key findings, a significant public concern is the potential for the construction project to be abandoned or stalled (“mangkrak”). Additionally, while the clustering results showed good cohesion, the cluster separation indicated a significant overlap in the data. This is further reflected by the average similarity score of 0.4234972.   Keywords – YouTube, Text Clustering, K-Means, Nusantara Capital City (IKN)

Abstract

Tanggamus Regency has a large potential for plantation resources. More than 85% of its land is classified as suitable for cocoa cultivation. Optimizing this potential requires the use of superior cocoa clones with pod morphological characteristics that support high productivity. This study aims to determine the quantitative pod morphological characteristics of 5 cocoa clones and identify the most suitable clones for cultivation in Suka Agung Village, Bulok District, Tanggamus Regency. The research method is a survey with a purposive sampling method. Quantitative pod morphological data were analyzed using ANOVA and DMRT at a significance level of 5%. The results showed that MCC 01 and MCC 02 showed better quantitative characteristics than other clones. This was indicated by higher average pod diameter, number of seeds per pod, seed length, seed diameter, and number of seeds per 100 g. However, the MCC 01 clone is considered to have moderate resistance to Vascular Streak Dieback (VSD) and Cocoa Pod Borer (CPB). In conclusion, MCC 02 is suitable for cocoa cultivation in Suka Agung Village, Lumbok District, Tanggamus.

Abstract

Bibit kelapa sawit yang berkualitas dapat terpenuhi apabila dalam proses pembibitan dilakukan pemeliharaan yang berkelanjutan. Upaya berkelanjutan tersebut salah satunya dapat diterapkan melalui pengurangan dosis pupuk anorganik dan diimbangi dengan penambahan pupuk organik. Penelitian ini bertujuan untuk memperoleh dosis pupuk NPK dan pupuk organik cair kotoran sapi terbaik, serta interaksi keduanya dalam mengoptimalkan pertumbuhan bibit kelapa sawit di main nursery. Penelitian akan dilaksanakan di Usaha Pembibitan Kelapa Sawit, Politeknik Negeri Lampung. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok (RAK) pola faktorial 3 x 3 dengan 3 ulangan. Faktor pertama adalah dosis NPK dengan taraf dosis 0 g, 2.5 g, dan 5 g. Faktor kedua adalah dosis pupuk organik cair (POC) kotoran sapi dengan taraf dosis 0; 100; dan 200 ml polibag-1. Hasil penelitian menunjukkan bahwa penggunaan NPK 5 g polibag-1 sekali dalam dua minggu efektif dalam meningkatkan tinggi tanaman, diameter bonggol bibit, jumlah pelepah daun, dan tingkat kehijauan daun pada 16 minggu setelah aplikasi perlakuan pertama. Penggunan POC kotoran sapi dengan dosis 200 ml polibag-1 hanya mampu meningkatkan diameter bonggol bibit kelapa sawit. Tidak ada interaksi antara perlakuan NPK dan POC kotoran sapi.

Abstract

Media tanam topsoil untuk pembibitan kakao semakin terbatas dan sebagai alternatif dapat digunakan tanah subsoil, tetapi kesuburannya ditingkatkan dengan penambahan asam humat. Selain itu, untuk mengurangi penggunaan pupuk anorganik pada tahap pembibitan dapat digunakan pupuk hayati Plant Growth Promoting Rizhobacteria (PGPR). Penelitian ini bertujuan untuk memperoleh konsentrasi asam humat dan PGPR terbaik, serta interaksi keduanya dalam mengoptimalkan pertumbuhan bibit kakao di media tanam subsoil. Penelitian dilaksanakan di lahan kebun bibit tanaman perkebunan, Laboratorium Pengelolaan Tanaman Perkebunan, Politeknik Negeri Lampung. Penelitian menggunakan Rancangan Acak Kelompok (RAK) pola faktorial  dengan tiga ulangan. Faktor pertama adalah konsentrasi asam humat (tiga taraf: 0; 5; dan 7,5 g/L). Faktor kedua adalah konsentrasi PGPR (empat taraf: 0; 25; 50; dan 75 mL/L). Data dianalisis menggunakan analisis sidik ragam, dan dilanjutkan dengan uji lanjut jarak berganda Duncan (DMRT) pada taraf nyata 5%.  Hasil penelitian menunjukkan bahwa terdapat interaksi antara asam humat dengan PGPR pada tingkat kehijauan daun dan bobot kering tajuk, dengan konsentrasi paling optimum pada perlakuan 0 g/L asam humat + 25 mL/L PGPR dan 5 g/L asam humat + 50 mL/L PGPR.  Pemberian asam humat secara mandiri berpengaruh pada bobot kering akar dengan perlakuan terbaik pada konsentrasi 0 g/L dan  5 g/L asam humat, dan pada luas daun untuk konsentrasi 0 g/L asam humat. Pemberian PGPR secara mandiri berpengaruh pada bobot kering akar, luas daun, dan jumlah daun 30 HSA. Konsentrasi aplikasi PGPR terbaik untuk bobot kering akar dan luas daun adalah 75 mL/L, sedangkan untuk jumlah daun 30 HSA adalah 50 mL/L.

Abstract

Research on caffeine biosynthesis in Coffea canephora has expanded across multiple disciplines, yet its global genetic research trends remain insufficiently mapped. This study aimed to analyze the development and thematic structure of genetic research on caffeine biosynthesis in C. canephora using a bibliometric approach. Data were retrieved from the Scopus database through keyword-based sampling and filtered based on relevance to genetic and biosynthetic aspects. Bibliometric analyses were conducted to examine publication trends, authorship patterns, country contributions, and keyword co-occurrence networks. The results show a significant increase in publications since the early 2000s, with dominant contributions from the United States, Brazil, and China. Keyword mapping reveals four major research clusters, including plant metabolism, clinical and nutritional studies, experimental models, and genetic variability. However, studies explicitly focusing on the genetic regulation of caffeine biosynthesis, particularly involving N-methyltransferase genes, remain relatively limited compared to broader multidisciplinary themes.These findings indicate that caffeine research in C. canephora is highly interdisciplinary but still lacks a strong emphasis on genetic mechanisms, highlighting the need for more targeted molecular and genomic studies to support coffee improvement and functional trait development.

Abstract

The development of non-invasive methods is essential for monitoring critically endangered species such as the Dicerorhinus sumatrensis. This study aimed to evaluate the potential of tree bark associated with rubbing behavior as a source of environmental DNA (eDNA) for species detection in Way Kambas National Park. A total of 30 samples were collected from tree bark surfaces showing evidence of rubbing activity. DNA was extracted and analyzed using two approaches: simple electrophoresis and polymerase chain reaction (PCR)-based molecular methods. The results showed that the simple method failed to detect visible DNA bands, indicating low DNA concentration and degradation in environmental samples. In contrast, PCR amplification successfully detected DNA in 5 out of 30 samples, including hair-derived and epithelial residues associated with rubbing behavior.containing hair residues produced more reliable detection compared to those with only epithelial traces. These findings demonstrate that tree bark able to serve as a potential non-invasive source of eDNA, particularly when analyzed using sensitive molecular techniques. This approach provides an alternative method for detecting elusive species and contributes to the development of effective conservation strategies for the sumatran rhinoceros.

Abstract

This study investigates cytogenetic evolution and research trends in Coffea spp. by integrating bibliometric analysis with karyotype-based evidence. Despite the rapid advancement of genomic research in Coffea spp., the integration of cytogenetic perspectives into broader research trends remains limited. Bibliometric data were retrieved from the Scopus database, covering publications from 1937 to 2026, resulting in 383 articles and reviews analyzed using Biblioshiny through thematic mapping and thematic evolution approaches. The results indicate that coffee genetic research has progressively shifted toward molecular and genomic studies, particularly those related to genetic variation, genome-wide association studies, and high-throughput analytical methods. In contrast, cytogenetic themes, including chromosome organization, karyotype variation, and polyploidization, remain comparatively underrepresented within the broader research landscape. Thematic evolution analysis further reveals a transition from foundational genetic studies to advanced genomic frameworks over time. Cytogenetic synthesis highlights major differences among key coffee species, with Coffea arabica characterized as an allotetraploid species (2n = 44), whereas C. canephora and C. liberica exhibit diploid chromosome complements (2n = 22). These findings demonstrate that chromosome-level perspectives remain insufficiently integrated into contemporary genomic research despite their importance in understanding genome evolution and species differentiation. By combining bibliometric trends with cytogenetic evidence, this study provides a more comprehensive framework for interpreting coffee genome organization and emphasizes the importance of integrating structural and molecular approaches in future coffee research and breeding programs.
