Judul: Evaluation of Pod Dehiscent Resistance and  Productivity Levels of 22 Genotypes Green Beans (Vigna radiata L.) Selection  Results of IPB
Abstrak: Kacang hijau (Vigna radiata L. Wilczek) pada umumnya memiliki genotipe yang rentan mengalami pecah polong sehingga banyak terjadi kehilangan hasil sebelum panen dan saat panen. Penelitian ini bertujuan untuk mengevaluasi ketahanan pecah polong dan beberapa karakter agronomi galur-galur kacang hijau IPB. Penelitian dilaksanakan di kebun Percobaan Balai Penelitian Bioteknologi dan Sumberdaya Genetik Pertanian, Kecamatan Bogor Barat, Kota Bogor dari bulan November 2022 hingga bulan Maret 2023. Penelitian ini menggunakan rancangan kelompok lengkap teracak dengan tiga ulangan. Sebanyak 22 genotipe kacang hijau dan 2 varietas pembanding yaitu Vima 1 dan Vima 5 ditanam hingga sampai masa panen dan dilakukan pengamatan karakter agronomi serta persentase pecah polong. Hasil penelitian ini menunjukkan beberapa genotipe yang diuji memiliki karakter agronomi yang lebih baik dari pembanding. Genotipe F7- Lom2/129-42, F7- VR10/V1-29, F7-VR10/V1-10, F7-Lom2/129-2, dan F5-Lom2/129-125 memiliki karakter yang paling baik dari galur yang diuji dan lebih baik dari varietas pembanding. Galur-galur kacang hijau yang diuji bersifat toleran pecah polong., Mung bean (Vigna radiata L. Wilczek) has most of the genotypes that are prone to pod dehiscent resulting in a lot of yield loss before and during harvest. This study aims to evaluate the resistance to pod dehiscent and several agronomic characters of IPB's green bean lines. The research was conducted at the Experimental Garden of the Balai Penelitian Bioteknologi dan Sumberdaya Genetik Pertanian, West Bogor District, Bogor City from November 2022 to March 2023. This study used randomized complete group design with three replications. A total of 22 mung bean genotypes and 2 control varieties, namely Vima 1 and Vima 5, were planted up to harvest and observed for agronomic characters and the percentage of pod dehiscent. The results of this study indicated that some of the genotypes tested had better agronomic characteristics than the controls The genotypes F7-Lom2/129-42, F7-VR10/V1-29, F7-VR10/V1-10, F7-Lom2/129-2, and F5-Lom2/129-125 had the best characters from the strains tested and better than the comparison varieties. The strains of green beans tested were tolerant dehiscent of the pods.

Judul: Yield Test of 22 Mung Bean (Vigna radiata L.) Strains  Results of IPB Breeding
Abstrak: Kacang hijau merupakan tanaman legum yang telah dikenal secara luas di Indonesia karena kandungan proteinnya tinggi dan mudah dicerna, kadar lemaknya yang rendah, serta memiliki berbagai manfaat bagi kehidupan. Penelitian ini bertujuan untuk mendapatkan informasi tentang daya hasil 22 galur kacang hijau IPB. Penelitian ini dilaksanakan pada bulan November 2022 hingga Maret 2023 di Kebun Percobaan Balai Penelitian Bioteknologi dan Sumberdaya Genetik Pertanian, Kota Bogor. Penelitian ini terdiri dari satu faktor yaitu 22 genotipe kacang hijau IPB dan dua varietas pembanding. Rancangan percobaan yang digunakan yaitu rancangan kelompok lengkap teracak dengan 3 ulangan. Hasil penelitian menunjukkan adanya perbedaan yang nyata antara genotipe yang diuji. Genotipe yang memiliki produktivitas yang lebih tinggi dibandingkan dengan genotipe pembanding secara deskriptif diantaranya F7-Lom2/129-2, F7- Lom2/129-28, F7-VR10/V1-6, F7-VR10/V1-10, F7-VR10/V1-29, F6- VR422H/129-1, F5-Lom2/129-125, F6-VR480B-213, dan F6-Lom2/V2-6., Mung bean is a legume crop that is widely known in Indonesia because of its high protein content and ease of digestion, low-fat content, and various benefits for life. This study aims to obtain information about the yield of 22 IPB mung bean lines. This research was conducted from November 2022 to March 2023 at the Experimental Garden of the Agricultural Genetic Resources and Biotechnology Research Institute, Bogor City. This study consisted of one factor, namely 22 IPB mung bean genotypes, and two control varieties. The experimental design used was a randomized complete block design with 3 replications. The results showed that there were significant differences between the genotypes tested. The genotypes that had higher productivity compared to the comparative varieties descriptively included F7-Lom2/129-2, F7-Lom2/129-28, F7-VR10/V1-6, F7-VR10/ V1-10, F7-VR10/V1-29, F6-VR422H/129-1, F5-Lom2/129-125, F6- VR480B-213, and F6-Lom2/V2-6.

Judul: Penggunaan Teorema Homeomorphy 2-Manifold dan Teorema Euler Poincare pada Torus 𝑇�� dan Simplicial Complex 𝐾��
Abstrak: Two dimensional topological spaces are said to be homeomorphic if they have the same topological invariant, where one of topological invariant used is an Euler characteristic. Homeomorphy 2-Manifold’s Theorem and Euler Poincare’s Theorem are used to distinguish two topological spaces. Homeomorphy 2-Manifold’s Theorem uses Euler characteristic to identify two dimensional topological spaces. Euler Poincare’s Theorem is an alternative way to find Euler characteristic with Betti number, which is topological invariant as well. The objective of this paper is to investigate the homeomorphism of torus 𝑇����� and simplicial complex 𝐾�����. Topological space torus and simplicial complex 𝐾����� have the same Euler characteristic, which is two. Based on Homeomorphy 2-Manifold’s Theorem topological space torus 𝑇����� and simplicial complex 𝐾����� is homeomorphic.
