Judul: Evaluation of 100 Lowland Rice Lines (Oryza sativa L.) in F3 Generation of IPB196 population
Abstrak: Lahan pertanian semakin menyempit dan jumlah penduduk semakin bertambah, sehingga perlu pemuliaan tanaman untuk mengatasi hal tersebut. Penelitian ini bertujuan menguji keragaman keragaan 100 galur padi generasi F3 populasi IPB196. Penelitian dilaksanakan di Kebun Percobaan Sawah Baru IPB, Desa Babakan, Dramaga, Bogor pada Februari sampai Agustus 2022. Penelitian ini menggunakan rancangan augmented design dengan menggunakan rancangan lingkungan rancangan kelompok lengkap teracak (RKLT). Digunakan dari 6 pembanding, yaitu dua variets (Ciherang, Inpari32) dan 4 galur padi tipe baru (PTB) ((IPB187-F-37-1-2 (S1), IPB187-F-65-1-2 (S3), IPB193-F-30-2-1 (S9), dan IPB187-F-40-1-1(T5)) dengan 5 ulangan, serta genotipe yang diuji berjumlah 100 galur generasi F3. Karakter panjang batang memiliki kisaran 59,76-88,91 cm dengan kisaran jumlah gabah total per malai 110,35-202,15 g, jumlah anakan antara 4-20 anakan, serta bobot gabah per rumpun berkisar 12,34-62,33 g. Keragaman semua karakter yang diamati termasuk kedalam keragaman sempit dan penampilan yang seragam, ditunjukkan dengan nilai koefisien keragaman genetik (KKG) dan koefisien keragaman fenotip (KKF) yang rendah. Hasil penelitian menunjukkan terdapat sebelas galur menghasilkan bobot gabah per rumpun antara (35,96-62,33 g, lebih tinggi) dari pembanding VUB (23,71 g dan 29,36 g) dan pembanding galur PTB (37,18–38,94 g)., Agricultural land decreases while the population is increasing, so plant breeding is needed to overcome this. This study aims to evaluate the variation performance of 100 F3 lowland rice of the IPB196 population and study their variation, as well as to select the best lines that have high yield potential. The research was carried out at the IPB196. Experimental Farm in Sawah Baru, Babakan Village, Dramaga, Bogor from February to August 2022. This study used an augmented design using a randomized complete group design (RKLT). Six checks are used for two varieties (Ciherang and Inpari32) and four lines of a new rice plant type (NPT) (IPB187-F-37-1-2 (S1), IPB187-F-65-1-2 (S3), and IPB193-F-30-2-1 (S9)), the total number of genotypes evaluated is 100 F3 generations with five replications. The stem length characters ranged from 59.76, to 88.91 cm, with total grain numbers per panicle ranging from 110.35, to 202.15 g, and tillers ranging from 4 to 20. The weight of grain per clump ranges from 12.34 to 62.33 g. The variation of all observed characters belongs to narrow variation and has a uniform appearance, as indicated by low genetic variation coefficient and phenotypic variation coefficient values. The results showed that there were eleven lines that had to produce higher grain weights per clump (from 35.96 to 62.33 g, higher). The VUB check (23.71 g and 29.36 g) and the NPT lines check (37.18 to 38.94 g).

Judul: EVALUATION OF 100 LINES OF RICE FIELDS (Oryza sativa L.) GENERATION F3 POPULATION IPB196 AND IPB197
Abstrak: Produksi padi di Indonesia belum mengalami peningkatan yang signifikan karena luas lahan yang semakin sempit sedangkan jumlah penduduk di Indonesia semakin bertambah. Padi Tipe Baru (PTB) menjadi salah satu cara untuk meningkatkan produksi tanaman padi. Penelitian ini bertujuan menguji 100 galur padi generasi F3 populasi IPB196 dan populasi IPB197 untuk memperoleh galur galur yang berpotensi hasil tinggi. Penelitian dilaksanakan di Kebun Percobaan Sawah Baru IPB, Desa Babakan, Dramaga, Bogor pada bulan Februari sampai Agustus 2022. Penelitian ini menggunakan rancangan bersekat (augmented design) menggunakan rancangan kelompok lengkap teracak (RKLT) dengan enam pembanding yakni VUB Ciherang, Inpari 32, dan empat galur elit IPB187-F-37-1- 2 (S1), IPB187-F-65-1-2 (S3), IPB193-F-30-2-1 (S9), dan IPB187-F-40-1-1 (T5) dengan lima ulangan dan 100 galur generasi F3 populasi IPB196 dan IPB197 tidak diulang sehingga diperoleh 130 satuan percobaan. Hasil penelitian menunjukkan galur-galur PTB bersegregasi cukup baik dan memungkinkan untuk dilakukan seleksi lebih lanjut pada generasi berikutnya. Beberapa galur memiliki keragaan yang lebih baik dan menghasilkan bobot gabah per rumpun yang lebih besar dari pembanding VUB Ciherang dan Inpari 32 yaitu galur IPB196-101 (32,94 g), IPB196-105 (43,78 g), IPB196-106 (35,54 g), IPB196-108 (32,40 g), IPB196-112 (39,73 g), IPB196-114 (39,28 g), IPB197-121 (50,55 g), IPB197-123 (46,09 g), IPB197-126 (46,30 g), IPB197-127 (44,31 g), IPB197-130 (50,45 g), IPB197-139 (36,12 g), IPB197-171 (38,89 g), dan IPB197-200 (41,07 g). Galur potensial padi pada populasi IPB196 yang paling baik yaitu galur IPB196-105 (43,78 g), dan pada populasi IPB197 yaitu galur IPB197-130 (50,45 g), serta memiliki karakter agronomi yang lebih baik daripada seluruh pembanding., Rice field production in Indonesia has not experienced a significant increase because the land area is getting smaller while the population in Indonesia is increasing. Rice breeders consider that New Plant Type of Rice (NPT) is one way to increase rice production. This study aims to evaluate 100 lines of rice generation F3 of the IPB196 and IPB197 populationsto stufy the segregation of the populations in obtaining potentially high yielding lines. The research was conducted at the IPB Field Experimental Station, Babakan Village, Dramaga, Bogor from February to August 2022. This study used augmented randomized complete block design (RCBD) with six controls consisted of two varieties, Ciherang, Inpari 32, and four elite inbred lines IPB187-F-37-1-2 (S1), IPB187-F-65-1-2 (S3), IPB193 -F-30-2-1 (S9), and IPB187-F-40-1-1 (T5). Check genotypes were planted in five replications, and the 100 segregating lines of F3 generation of the IPB196 and IPB197 were planted without replication so that 130 experimental units were obtained. The results showed that several New Plant Type (NPT) lines segregated quite well and made it possible to carry out further selection for the next generation. Several lines had better performance and produced higher grain weight per clump than the comparisons between VUB Ciherang and Inpari 32. Those lines IPB196-101 (32,94 g), IPB196-105 (43,78 g), IPB196-106 (35,54 g), IPB196-108 (32,40 g), IPB196- 112 (39,73 g), IPB196-114 (39,28 g), IPB197-121 (50,55 g), IPB197-123 (46,09 g), IPB197-126 (46,30 g), IPB197-127 (44,31 g), IPB197-130 (50,45 g), IPB197- 139 (36,12 g), IPB197-171 (38,89 g), and IPB197-200 (41,07 g). The best potential rice lines in the IPB196 population were IPB196-105 (43,78 g), and in

Judul: Pelabelan Super Vertex Magic
Abstrak: Super vertex magic labeling is labeling on graph with is a set of edges mapped into and is a set of vertices mapped into . It has a vertex magic labeling in which and represents the size and order of the graph respectively. This manuscript proves that paths, cyclics, and disjoint union of cyclics have a super vertex magic labeling. There are four theorems to be discussed. The first theorem proves that path is super vertex magic if and only if is odd and . The second theorem proves that cyclic is super vertex magic if and only if is odd. The third theorem proves that bijection function from an edge set onto of graph can be extended to a super vertex magic labeling if and only if the set amount of edge label that incidents with a vertex in the graph, consists of sequential integers as many as vertices in the graph. The fourth theorem proves that disjoint union of the cyclics consists of cyclics with each cyclic has vertices is super vertex magic if and only if and are odd.
