Abstract

This study was conducted to determine the effect of different jajar legowo planting systems in intercropping sweet corn with peanuts, as well as the addition of several doses of organic fertilizer on soil nitrogen status and plant leaf tissue on sandy soil. The research was conducted from January to May 2023, on the south coast of Jember Regency. The study used a split-plot design; the main plot consisted of the treatment of 2:2 (A1) and 4:2 (A2) jajar legowo intercropping systems. The subplots were different doses of cow dung organic fertilizer: 10 t ha-1 (B1), 20 t ha-1 (B2), and 30 t ha-1 (B3), each repeated three times. Observational data were analyzed by ANOVA and DMRT 5%. The results of the study showed that the combination of the planting system and organic fertilizer doses applied had not been able to provide optimal microclimate and soil properties for the growth and development of sweet corn plants. The A2 planting system provides a better microclimate and plant morphology for plant N availability and absorption. The addition of organic fertilizer up to the highest dose (B3) has not been able to maintain optimal soil water and N availability for sweet corn in sandy soil.

Abstract

Porang (Amorphophallus muelleri B.) is a tuberous plant with the potential to be the main source of carbohydrates and is rich in benefits. Porang proliferation is limited by a 6-month dormancy period per year, and generative propagation is unlikely due to the seeds being apomictic triploid. The aimed of my research to analyze the application of BAP and NAA in culture media for direct propagation of porang shoots. The explant used in this research was young leaves. The research was arranged in a completely randomized design with a combination of BAP and NAA hormones added to the MS medium. There were three BAP treatments, namely 1.0 mg/L, 2.0 mg/L, and 3.0 mg/L, while NAA treatments consisted of 2 levels, namely 2.0 mg/L and 4.0 mg/L. The addition of 1.0 mg/L BAP combined with 4.0 mg/L NAA was the best treatment that produced seven shoots with an average shoot length of 2.14 cm and root length of 3.6 cm, with the earliest bud emergence (9.7 weeks after planting).

Abstract

The intensive farming system was still carried out by most farmers in Mayangan Village, Jember Regency, by implementing massive use of inorganic fertilizers. Thus, the activity has impacted the decrease in land quality and plant production. This community service aimed to educate farmers and initiate Integrated Farming System (IFS) in Mayangan Village. The community service was done for 6 months by steps; socializing, division work, practice, and evaluation. The community service was held in collaboration with the Ecophysiology of Tropical Plant Research Group (KeRis), University of Jember with farmers and livestock breeders from several farmer groups in Mayangan Village. The community service that has been carried out has made farmers more aware of the importance of integrated farming, especially the use of organic fertilizers in horticultural plant cultivation in Mayangan Village. This community service also increases cooperation between farmers and livestock breeders who collaborate to realize sustainable agriculture. Livestock waste can be processed into fertilizer, agricultural by-products can be used as animal feed, and during the process, soil fertility can be maintained properly, which is expected to increase the productivity of horticultural plants in Mayangan Village.

Abstract

Greenhouse berfungsi untuk menciptakan lingkungan mikro yang baik bagi pertumbuhan tanaman. Lebih jauh lagi, fungsi greenhouse pada daerah tropis adalah melindungi tanaman dari intensitas radiasi matahari berlebih, mengurangi penguapan air dari daun dan media tanam, dan mengurangi resiko serangan hama penyakit. Penelitian ini bertujuan mengembangkan desain greenhouse yang lebih fleksibel namun memiliki fungsi sebagai rumah tanaman yang handal serta mempunyai stabilitas struktur yang baik. Desain greenhouse yang dikembangkan pada penelitian ini merupakan greenhouse dengan sistem modular sehingga dapat mudah dipindahkan dan mudah dirakit kembali. Greenhouse lipat modular ini dikembangkan dalam modul modul terpisah sehingga mudah dipindahkan dan ringan. Greenhouse ini dikembangkan terutama untuk memenuhi kebutuhan pengguna yang menginginkan greenhouse yang kompak, mudah dimobilisasi, dan mudah dirakit. Berdasarkan hasil pengujian pada prototipe yang telah dibuat, diketahui bahwa tingkat fleksibilitas greenhouse cukup baik dan dapat dirakit kurang dari 1 jam. Namun dari uji fungsional diketahui bahwa greenhouse lipat modular ini belum cukup baik untuk menyediakan suhu dan kelembapan yang optimal bagi tanaman sehingga dibutuhkan perbaikan pemilihan material dinding sidewall bawah agar sirkulasi udara secara alami dapat optimal.
