Abstract

Rizobakteri adalah kelompok bakteri yang hidup berkoloni di area perakaran berperan mendukung pertumbuhan dan perkembangan tanaman. Penelitian ini bertujuan untuk mengetahui interaksi antara isolat rizobakteri indigenous dan varietas terhadap pertumbuhan tanaman nilam Aceh. Penelitian ini dilaksanakan di Laboratorium Ilmu dan Teknologi Benih Jurusan Agroteknologi Fakultas Pertanian Universitas Syiah Kuala, Darussalam Banda Aceh dan Kebun Nino Park, Sektor Timur mulai Oktober 2020 sampai Februari 2021. Percobaan ini menggunakan rancangan acak kelompok (RAK) pola faktorial 10x3 dengan 3 ulangan. Ada 2 faktor yang diteliti, faktor pertama adalah jenis isolat rizobakteri (R) yang terdiri dari 10 taraf (PS 4/2, PS 5/6C, PS 6/3A, PS 7/1, 8/4K, PS 8/8 PK, KI 8/1, KI 8/3, CL 4/1), dan Faktor kedua adalah jenis varietas (V) yang terdiri dari 3 taraf (Tapaktuan, Lhokseumawe, Sidikalang). Hasil penelitian menunjukkan terdapat interaksi yang sangat nyata antara faktor isolat rizobakteri dan varietas.  Kombinasi terbaik terdapat pada isolat rizobakteri PS 4/2 dan varietas Tapak Tuan pada peubah jumlah daun dan cabang umur 8 dan 12 MSA dan isolat rizobakteri KI 8/3 dan varietas Sidikalang pada peubah jumlah cabang 8 dan 12 MSA. Kombinasi isolat rizobakteri PS 6/3A dan varietas Sidikalang dan varietas Lhokseumawe berturut-turut pada peubah jumlah daun 8 dan 12 MSA, serta kombinasi isolat rizobakteri KI 8/1 dan varietas Lhokseumawe pada peubah jumlah daun 8 MSA. Ability Testing of Indigenous Rhizobacteria Isolates from Several Sources of Location as Plant Growth Promoting Rhizobacteria (PGPR) on The Growth of Three Variety of Aceh Patchouli Plants Rhizobacteria are a group of bacteria that live in colonies in the root area and play a role in supporting plant growth and development. This study aims to determine the interaction between indigenous rhizobacteria isolates and varieties on the growth of Aceh patchouli. This research was carried out at the Seed Science and Technology Laboratory, Department of Agrotechnology, Faculty of Agriculture, Universitas Syiah Kuala , Darussalam Banda Aceh and Nino Park Gardens, Sektor Timur from Oktober 2020 to February 2021. This experiment used a 10x3 factorial randomized block design (RAK) with 3 replications. There are 2 factors studied, the first factor is the type of rhizobacteria isolate (R) which consists of 10 levels (PS 4/2, PS 5/6C, PS 6/3A, PS 7/1, 8/4K, PS 8/8 PK, KI 8/1, KI 8/3, CL 4/1) and the second factor is the type of variety (V) which consists of 3 levels (Tapaktuan, Lhokseumawe, Sidikalang). The results showed that there was a very significant interaction between rhizobacteria isolates and varieties. The best combination was found in PS 4/2 rhizobacteria isolates and Tapak Tuan varieties on the variable number of leaves and branches aged 8 and 12 MSA and rhizobacteria isolates KI 8/3 and Sidikalang varieties on the variables number of branches 8 and 12 MSA. The combination of rhizobacteria isolates PS 6/3A with Sidikalang and Lhokseumawe varieties on leaf number variables 8 and 12 MSA, respectively, and the combination of rhizobacteria isolates KI 8/1 and Lhokseumawe varieties on leaf number variables 8 MSA

Abstract

Land is a critical factor in agriculture, especially in soil-based cultivation. The prevailing problem in agricultural land use that is yet to be solved is the rapid conversion to non-agricultural use, which raised concern for agriculture’s existence in the future. Moreover, the population continues to grow despite the receding agricultural land to produce food. Therefore, research and policies are starting to lean towards optimization of marginal land for agricultural activities. Indonesia still has potential marginal land for agricultural expansion. This paper uses secondary data and former studies to summarize the potential and availability of marginal land for agricultural expansion based on the land categories: forest land, dryland, and wetland (tidal swamp and peat). This paper also discusses the government's extensification program and the results of its implementation. We found that various reports about marginal lands utilization emphasized optimizing the target land with appropriate agricultural technology. The presentation of data obtained through literature studies can strengthen the opinion that the potential availability and potential for expansion of agricultural land in Indonesia is real. This paper is expected to provide a comprehensive reference for all Indonesian regional governments, so stakeholders continue optimizing the potential of existing natural resources.

Abstract

Bitter gourd (Momordica charantia L.) fruits have been reported to have pharmacological functions such as anti-bacterial, lowering blood sugar, and preventing cardiovascular disease. Terpenoids are the bioactive compounds that play a role in those functions. The phosphorus is essential in the biosynthesis of terpenoids. This research aimed to determine plant growth characteristics, fruit production, and terpenoid production in bitter gourds fertilized with various phosphorus. The experiment was conducted at the IPB experimental station in Cikarawang, 6o32’58.3” S south latitude and 106o43’54.8” E east longitude, Bogor, Indonesia, from July to October 2023. The experiment used a completely randomized block design with a single factor: fertilizer treatments and three replications. The treatments were without fertilizer, chicken manure only, and varying dosages of SP-36 (0, 20, 40, 60 g per plant). Plants treated with 40 g SP-36 per plant significantly had longer stems at four weeks after planting (WAP) (153.5 cm), substantially more female flowers at 5 WAP (6.4 flowers), heavier fresh weight per fruit (243.98 g), and higher fruit carotene level (86 μg.g-1). Plants treated with 60 g SP-36 per plant had the heaviest fresh fruit weight per plant (2,820.9 g). On the other hand, chicken manure fertilizer resulted in an elevated number of female flowers at 7 WAP (6.8 flowers), leaf potassium content (3.41%), chlorophyll a (250 μg.g-1), chlorophyll b (114 μg.g-1), and total chlorophyll concentration (363 μg.g-1). There were no significant differences in IC50, terpenoid content, and terpenoid production; however, plants treated with 60 g SP-36 per plant tended to have lower IC50 (1,347.67 ppm) and terpenoid content (95,227 μmol NE.g-1 dry fruit). In contrast, plants treated with 40 g SP-36 per plant tended to have higher terpenoid production (15,995 mmol NE per plant) than other treatments.

Abstract

Aklimatisasi merupakan fase krusial dalam perbanyakan anggrek secara in vitro karena menentukan keberhasilan adaptasi planlet terhadap kondisi ex vitro serta keberlanjutan pertumbuhan tanaman. Penelitian ini bertujuan untuk mengkaji pengaruh jenis media aklimatisasi dan jenis pupuk daun terhadap keberhasilan aklimatisasi dan pertumbuhan planlet anggrek Dendrobium lineale Blue. Penelitian menggunakan rancangan percobaan faktorial dengan dua faktor, yaitu media tanam yang terdiri atas sabut kelapa dan pakis, serta jenis pupuk daun Gandasil D (20:15:15) dan Growmore (32:10:10). Parameter pertumbuhan yang diamati meliputi panjang akar dan beberapa variabel pertumbuhan planlet selama masa aklimatisasi. Hasil penelitian menunjukkan bahwa penggunaan media tanam sabut kelapa menghasilkan panjang akar planlet Dendrobium lineale Blue yang lebih baik dibandingkan dengan media pakis. Keunggulan media sabut kelapa diduga berkaitan dengan kemampuannya dalam mengikat dan menyimpan air, memiliki porositas yang baik, serta menyediakan unsur hara esensial yang mendukung pertumbuhan dan perkembangan sistem perakaran. Sementara itu, pemberian pupuk daun Gandasil D (20:15:15) dan Growmore (32:10:10) menunjukkan pengaruh yang relatif sama terhadap pertumbuhan planlet selama aklimatisasi, yang ditunjukkan oleh tidak adanya perbedaan nyata pada seluruh variabel pengamatan. Hal ini mengindikasikan bahwa kebutuhan unsur hara planlet telah terpenuhi selama fase aklimatisasi. Hasil penelitian ini menegaskan pentingnya pemilihan media aklimatisasi yang tepat untuk meningkatkan keberhasilan adaptasi dan pertumbuhan
