Judul: Agronomic Performance of Nine Sorghum (Sorghum bicolor (L.) Moench) Varieties in Bogor
Abstrak: Sorgum (Sorghum bicolor (L.) Moench) merupakan salah satu tanaman pangan yang berpotensi dikembangkan sebagai tanaman pangan alternatif di Indonesia. Tingginya karbohidrat pada komoditas ini dapat mendukung upaya diversifikasi pangan. Sorgum juga dapat menjadi pakan ternak dan sebagai sumber energi. Tujuan penelitian ini ialah menguji penampilan pertumbuhan, komponen hasil dan hasil sembilan varietas sorgum di Bogor. Penelitian dilaksanakan pada bulan Januari sampai Mei 2024 di Kebun Percobaan Leuwikopo dan Laboratorium Pasca Panen, Departemen Agronomi dan Hortikultura, Fakultas Pertanian, IPB. Rancangan percobaan yang digunakan adalah rangkaian kelompok lengkap teracak (RKLT) faktor tunggal varietas. Hasil analisis ragam sembilan varietas sorgum menunjukkan bahwa varietas berpengaruh nyata terhadap semua karakter yang diamati, kecuali pada karakter bobot malai basah, bobot malai kering, dan bobot 100 butir. Varietas Bioguma 1 memiliki keunggulan pada karakter produktivitas (10 ton ha-1)., Sorghum (Sorghum bicolor (L.) Moench) is one of the food crops potentially to be developed as an alternative food source in Indonesia. The high carbohydrate content of this commodity can support food diversification efforts. It may be used also as feed and energy source source. The objective of this study was to examine the growth performance, yield components and yield nine sorghum varieties in Bogor. The research was conducted at Leuwikopo Experimental Farm and Post-Harvest Laboratory, Department of Agronomy and Horticulture, Faculty of Agriculture, IPB from January to May 2024. The experimental design used was randomized complete block design with single factor, namely genotypes which consisted of 9 varieties. The results of the analysis of variance of nine sorghum genotypes showed that genotype had a significant effect on all observed characters, except for the characters of fresh panicle weight, dry panicle weight, and 100-grain weight. Bioguma 1 variety achieved the highest grain productivity (10 ton ha-1).

Judul: Evaluation of Agronomic Performance and Yield  Sorghum Breeding lines IPB in Bogor
Abstrak: Sorgum (Sorghum bicolor (L.) Moench) merupakan salah satu tanaman pangan yang berpotensi dikembangkan sebagai tanaman pangan alternatif di Indonesia. Produktivitas sorgum di Indonesia berkisar 2,13 ton ha-1, sedangkan potensi sorgum adalah 4-5 ton ha-1. Peningkatan produktivitas sorgum masih perlu dikembangkan salah satunya dengan pemuliaan tanaman. Tujuan penelitian ini adalah mengevaluasi keragaan karakter agronomi dan daya hasil pada delapan galur harapan sorgum IPB serta mengidentifikasi galur potensial untuk didaftarkan sebagai varietas unggul baru. Penelitian dilaksanakan pada bulan Februari sampai Juli 2022 di Kebun Percobaan Leuwikopo dan Laboratorium Penelitian Pemuliaan Tanaman, Departemen Agronomi dan Hortikultura, Fakultas Pertanian, IPB. Rancangan percobaan yang digunakan adalah rangkaian kelompok lengkap teracak (RKLT) faktor tunggal genotipe. Hasil analisis ragam sebelas genotipe sorgum menunjukkan bahwa genotipe berpengaruh nyata terhadap semua karakter yang diamati, kecuali pada karakter kadar air bji. Galur uji A-18- 12-7-5, A-19-18-3-8, B-043-16-5-5, C-248-16-5-3-4 dan C-267-18-18-2-7 memiliki keunggulan pada karakter hasil per hektar., Sorghum (Sorghum bicolor (L.) Moench) is a food crops that has developed as an alternatives food crop in Indonesia. Sorghum productivity in Indonesia is 2,13 ton ha-1, while the potential is 4-5 ton ha-1. Increasing the sorghum productivity still needs to be done one of them by plant breeding. The purpose of this research was to evaluate the performent of agronomic and yield on eight promosing lines of sorghum IPB and identify potential lines to be registered as new superior varieties. The research was conducted from February to July 2022 at the Leuwikopo Experimental Field and Plant Breeding Laboratory, Department of Agronomy and Horticulture, Faculty of Agriculture, IPB University. The experimental design used was a randomized complete block design with a single factor is genotype. The result of analysis of varience (ANOVA) of the eleven sorghum genotype showed that the genotype had a significant effect on all observed character, except for the water content character. Lines A-18-12-7-5, A- 19-18-3-8, B-043-16-5-5, C-248-16-5-3-4 and C-267-18-18-2-7 had an advantage on the character of yield per hectare.

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
