Abstract

Induksi poliploidi pada bibit Phalaenopsis amabilis telah dilakukan menggunakan kolkisin secara in vivo. Induksi poliploidi dilakukan dengan meneteskan kolkisin pada pucuk bibit P. amabilis.  Tujuan penelitian ini adalah untuk mendapatkan konsentrasi kolkisin yang efektif untuk induksi poliploidi bibit P. amabilis dan  menghasilkan bibit P. amabilis poliploid. Percobaan disusun dalam rancangan kelompok lengkap teracak dengan satu faktor, yaitu konsentrasi kolkisin. Pucuk bibit P. amabilis ditetesi 0,01 ml kolkisin (0, 1000, 2000, 3000, 4000, dan 5000 mg L-1). Hasil percobaan menunjukkan bahwa peningkatan konsentrasi kolkisin dari 1000 sampai 5000 mg L-1 tidak berpengaruh nyata terhadap persentase hidup dan pertumbuhan bibit pada 24 minggu setelah perlakuan (24 MSP). Bibit P. amabilis poliploid dapat dihasilkan pada penetesan kolkisin 1000, 3000, 4000, dan 5000 mg L-1 dengan konsentrasi kolkisin paling efektif adalah 5000 mg L-1. Bibit poliploid memiliki ukuran stomata lebih besar dari bibit diploid sebaliknya kerapatan stomatanya lebih rendah.

Abstract

A consumption society is a group that is constantly engaged in consumption activities. However, consumption in this context has evolved from simply fulfilling basic human needs to a lifestyle. According to Baudrillard, the consumption pattern of postmodern society is characterized by a shift in orientation from life needs to lifestyle expressions. This study aims to analyze the consumptive behavior and lifestyle of fixed gear bicycle enthusiasts in Denpasar City using an explanatory descriptive qualitative approach and Jean P. Baudrillard's theory of consumption society. The results showed that fixed gear bikes are not only a means of transportation, but also a symbol of identity expression and lifestyle. The consumption of symbols gives birth to a society of spectacle where symbolic exchange creates social distance and differentiates individuals within the community. Preferences for bicycles, brands, styles, and associated values shape identities and groups within the community.

Abstract

This study aims to describe, analyze, and interpret the implementation of food security policies and strategies in Indonesia using the Mentality, System, and Networking (MSN) approach. The research employs a descriptive method, which is used to understand or depict the reality of the events under investigation. The focus of this study is directed toward three main approaches: the mentality approach, system approach, and networking approach. The researchers chose these three approaches because a public policy will become actual and directed in its implementation if it uses or considers the MSN-Approach Model The conclusions drawn from this study encompass three aspects: Mentality Approach: The attitudes, behaviors, and responsibilities of officials have demonstrated a caring attitude. The state has consistently committed to placing the food economy as something very important and strategic. The government's concern is also seen from Indonesia's participation in global food security development initiatives. System Approach: There are clear and explicit regulations regarding the government's obligations to realize food security. Law No. 18 of 2012 serves as evidence of the government's responsibility and seriousness in achieving food security. Networking Approach: This approach has been well implemented, as evidenced by the strengthening of food distribution infrastructure across Indonesia. Given the complexity of geographical challenges and uneven food distribution, the government has established collaborations and synergies with regional governments to build new markets and expand logistics networks connecting food production centers with consumer areas.

Abstract

Aksesi cabai IPBC12 telah diketahui memiliki gen ketahanan dominan terhadap PYLCV dan dapat dimanfaatkan sebagi donor gen untuk perakitan varietas cabai tahan PYLCV. PYLCV merupakan salah satu virus patogen penting pada pertanaman cabai di Indonesia. Identifikasi marka SSR polimorfik pada populasi persilangan antara IPBC12 dan varietas Yuni dilakukan untuk mendapatkan marka yang dapat digunakan untuk seleksi progeni hasil persilangan dan terpaut dengan sifat ketahanan terhadap PYLCV. Sebanyak 20 marka SSR dianalisis polimorfismenya pada dua tetua persilangan, kemudian marka yang polimorfik diuji pada galur generasi F1 dan F2. Hasil penelitian menunjukkan ada empat marka polimorfik pada kedua tetua persilangan, tetapi ketika diuji pada galur-galur keturunannya hanya 3 marka (CaBR61, CaBR64, dan CaBR98) yang polimorfik. Berdasarkan analisis marka, 14 galur F1 terkonfirmasi hasil persilangan antar aksesi IPBC12 dan varietas Yuni. Marka yang secara konsisten mendeteksi penurunan alel dari kedua tetua pada progeni F1 adalah CaBR61. Marka tersebut berpotensi sebagai marka seleksi galur-galur hasil persilangan pada tanaman cabai. Analisis molekuler pada galur-galur F2 tidak mendapatkan keterpautan antara marka dengan sifat ketahanan. Perlu analisis lebih lanjut menggunakan jumlah marka yang mencukupi dan tersebar merata dalam genom cabai untuk memetakan gen ketahanan terhadap PYLCV pada populasi persilangan antara aksesi IPBC12 dan varietas Yuni. Kata kunci: aksesi IPBC12, Capsicum annuum, seleksi berpandu marka, varietas Yuni

Abstract

The objective of this study was to identify the stability of seven sweet corn genotypes as breeding result of Center for Crop Improvement Studies (PSPT), using Additive Main Effect Multiplicative Interaction (AMMI) method. The design was Randomized Complete Block Design (RCBD) with three replications as blocks. The genotypes used were; PSPT-C, PSPT-K, PSPT-T1, PSPST-T2, PSPT-MM, and two commercial varieties Bogor-Hi and SD-2. The genotypes were planted in four different locations which included experiment fields of IPB-Cikabayan Darmaga (250 m above sea level) and Pasir Sarongge Cipanas (1120-1200 m above sea level), Gunung Geulis Cisarua (550 m above sea level), and Cibedug Ciawi (600 m above sea level). Based on the postdictive success and predictive success methods, the model used (AMMI 2) was able to explain interaction-influenced variation as much as 85%. The genotypes found stable in four locations were PSPT-MM, PSPT-T1, Bogor-Hi and SD-2. PSPT-C was specific for Ciawi, PSPT-K and PSPT-T2 specific for Cisarua.   Key words: AMMI, sweet corn, multilocation trials.

Abstract

A lot of plant materials are needed for successful back cross program of interspecific FI rice to their recurrent parents. Multiplication of the steril FI plants through tiller propagation is not adequate. The research aims to develop technique of vegetatif multiplication of interspesific hybrid rice utilizing nodal segments. In the vegetatif multiplication experiment, several factors were examined as treatments: nutrition culture (MS, Yoshida, and water), stum position (first, second and third) and growth media (vermiculite, husk charcoal, and sand). The plant materials are interspecific FI rice i.e. Ranah Sanra (genom AA) x O. officinalis 100870 (genom CC), Hawara Bunar (genom AA) x O. Punctata 9101411 (genom BB), Grogol (genom AA) x O. punctata 9101411 (genom BB), CT 6510-24-1-3 (genom AA) x O. malamphuzaensis 100957 (genom BBCC). Results of the study indicated that MS and Yoshida nutrition, stum without sheath, base of stum and sand media gave better growth more than other treatments.
