Abstract

Jeruk siam (Citrus nobilis var. Microcarpa) merupakan salah satu jenis jeruk yang potensial dan banyak dibudidayakan di Indonesia. Salah satu penyakit jeruk siam yang dapat menurunkan produktivitas serta kualitas adalah CVPD karena penyebarannya yang cepat. Peneltian ini bertujuan untuk mengevaluasi respon selang waktu pemberian pupuk cair terhadap pertumbuhan tanaman jeruk siam (Citrus nobilisvar. Macrocarpa) yang terserang CVPD. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) yang diulang sebanyak 8 kali, dengan perlakuan yang terdiri dari 1 kali semprot pada awal penelitian (S0), 10 hari sekali (S1) dan 30 hari sekali (S2). Hasil penelitian menunjukkan interval waktu penyemprotan 10 hari sekali (S1) terindentifikasi mampu meningkatkan pertumbuhan jeruk siam sebagaimana direpresentasikan melalui panjang daun, lebar daun, lingkar cabang dan klorofil daun. Kesimpulannya interval waktu tersebut direkomendasikan dalam pemberian pupuk cair untuk memicu pertumbuhan jeruk siam yang terserang CVPD. Siamese orange (Citrus nobilis var. Microcarpa) is one of the potential citrus varieties and is widely cultivated in Indonesia. One of the Siamese orange diseases that infects citrus plants and threatens global citrus production and quality is CVPD due to its rapid spread. This research aimed to evaluate the response time interval for application liquid fertilizer to the growth of Siamese oranges (Citrus nobilisvar. Macrocarpa) infected with CVPD. The experiment was arranged based on Randomized Block Design (RBD) was repeated 8 times, with treatments consist of one time spray at the beginning of the research (S0), once-every 10 days (S1) and once-every 30 days (S2). The results showed that spraying interval of once-every 10 days (S1) was identified being able to increase the growth of Siamese oranges as represented by leaf length, leaf width, branch circumference and leaf chlorophyll. To conclude, this time interval is recommended for application liquid fertilizer to stimulate the growth of Siamese oranges infected by CVPD

Zahwa, D.N.A., Lakitan, B., Muda, S.A., Ria, R.P., & Ramadhani, F.  (2023). Red romaine lettuce growth on different shading intensities and organic mulching with watering intensities. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang  21 Oktober 2023. (pp. 135-144).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Red romaine lettuce (Lactuca sativa L. var. longifolia) is a lettuce variety containing antioxidant, vitamin, and fiber contents that are beneficial in meeting dietary fiber requirements. This vegetable has the potential to be cultivated in suboptimal areas, including urban land. This study was aimed at identifying the impact of several shade intensities and organic mulch with watering intensities on romaine lettuce growth at early vegetative stages. The research followed a split plot design consisting of 2 treatments, namely shade intensity as the main plot (45% shade, 55% shade, and 80% shade) and organic mulch with watering intensities as subplots (without mulch with no intensive watering, organic mulch with no intensive watering, and organic mulch with intensive watering) and repeated 3 times. The results showed that shaded red romaine lettuce (45% shade, 55% shade, and 80% shade) increased growth at early vegetative growth. However, it was not statistically significant. Meanwhile, the application of organic mulch through intensive watering tends to increase shoot and root growth. Differences in shoot and root growth as a result of the treatments applied can also be shown through their visual appearance. Shade and mulch treatments by intensive watering were confirmed to be able to control the microclimate represented through media moisture. The 80% shading and the organic mulch with intensive watering were able to increase media moisture. In conclusion, 80% shading and organic mulch with watering improved red romaine lettuce growth at the early vegetative stage, although recovery to a lower shade is necessary to avoid inhibited root and shoot growth.

Abstract

Bibit kelapa sawit yang dibudidayakan memiliki peran besar untuk pertumbuhan dan hasil produksi selanjutnya. Penelitian ini bertujuan untuk memahami dampak penggunaan dosis dan selang waktu pemberian pupuk hayati terbaik pada pertumbuhan bibit kelapa sawit. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan dua faktor: konsentrasi atau takaran (T) dan selang waktu (S). Faktor T memiliki empat tingkat (T1: 25%, T2: 50%, T3: 75%, T4: 100%), sedangkan faktor S memiliki tiga selang waktu (W1: 5 hari, W2: 10 hari, W3: 15 hari). Variabel yang diamati berupa data pertumbuhan tanaman selama fase vegetatif. Hasil penelitian menunjukkan bahwa pengaplikasian pupuk cair biofitalik dapat meningkatkan pertumbuhan bibit kelapa sawit berumur tiga bulan. Konsentrasi 100% dan selang waktu 5 hari berpengaruh positif terhadap tinggi tanaman dan total luas daun. Konsentrasi 100% dan selang waktu 15 hari berpengaruh baik pada jumlah daun. Konsentrasi 100% dan selang waktu 10 hari berpengaruh positif pada diameter batang. Konsentrasi 100% dan selang waktu 5 hari juga berdampak baik pada total luas daun.

Abstract

Mustard greens are one of the vegetable commodities plants. The part used is the young leaves, which can be processed into traditional medicinal and vegetable ingredients that benefit human health. This research aims to determine the level of shade tolerance on the growth and yield of mustard plants and determine mustard varieties that are tolerant of minimum sunlight conditions. This research was carried out in experimental fields using artificial fields in June – July 2023. This research used a split-plot design with 2 factors. Tafif shade as the main plot consists of no shade 0%, 55%, 70%, and 95%. The sub-plot varieties consist of the Tosakan variety and the Kumala variety. The results of the research indicate that sunlight intensity reduction negatively impacted the growth and yield of mustard plants. However, under 55% shade conditions, there was no significant difference observed in the growth and yield of mustard plants compared to those grown without shade. The Tosakan and Kumala varieties did not show any differences in the growth or yield of mustard plants.

Abstract

Sorghum (Sorghum bicolor L. Moench) plant is native to tropical and subtropical countries with high suitability for planting on marginal land. Therefore, this research aimed to determine the use of dolomite and vermicompost in tidal swamp soil for the growth and yield of sweet sorghum plants at the Experimental Garden and the Chemistry, Biology and Soil Fertility Laboratory, Department of Soil Science, Faculty of Agriculture, Sriwijaya University. A factorial randomized complete block design (FRCBD) consisting of two factors was used. The first factor was dolomite namely 0 ton.ha−1, 6 ton.ha−1, 9 ton.ha−1, and 12 ton.ha−1, while second factor was vermicompost including 0 ton.ha−1, 3 ton.ha−1, 6 ton.ha−1, and 9 ton.ha−1. The results showed that the application of Dolomite had a very significant effect on soil pH, N-total, P-available, and potassium exchangeability. In addition, dolomite increased plant height, number of leaves, chlorophyll content, fresh and dry weight shoot, number of grains, and weight of 1000 grains.

Abstract

  Lahan pertanian yang semakin terbatas mendorong kegiatan budidaya tanaman dapat dilakukan tidak hanya di lahan luas. Salah satu upaya yang dapat dilakukan yaitu dengan pemanfaatan lahan terbatas untuk kegitan budidaya. Budidaya tanaman di pekarangan memiliki potensi untuk meningkatkan ketahanan pangan khususnya di desa. Pemanfaatan lahan terbatas dapat dioptimalkan melalui penerapan tenkologi inovasi seperti hidroponik, vertikultur, ataupun aquaponik. Umumnya, banyak masyarakat di desa belum memanfaatkan lahan pekarangan secara optimal untuk kegiatan budidya tanaman. Hal ini disebabkan oleh minimnya informasi atau pengetahuan dalam mengoptimalkan lahan untuk budidaya tanaman sebagai upaya untuk meningkatkan ketahanan pangan di tingkat rumah tangga. Tujuan dari pengabdian ini adalah untuk memberikan informasi dan pemahaman terkait potensi pertanian pekarangan yang diintergarsikan dengan penerapan pertanian organik. Kegiatan pegabdian ini dilakukan dengan metode sosialisasi dan pelatihan langsung di desa permata baru. Kegiatan sosialisasi dan pelatihan terkait penerapan sistem pertanian hidroponik dan cara perakitannya serta pembuatan pupuk organik cair dari limbah kulit pisang dan biopestisida dari daun pepaya. Berdasarkan survey terdapat beberapa kendala mengapa masyarakat tidak memanfaatkan lahan pekarangan diantaranya karena keterbatasan biaya produksi, minimnya pengetahuan dan kendala teknis. Hasil dari pengabdian ini tercermin dalam peningkatan minat masyarakat untuk mengimplementasikan sistem pertanian hidroponik.  Dengan terlaksananya kegiatan pengabdian ini melalui sosialisasi dan pelatihan masyarakat desa mulai menyadari potensi lahan pekarangan untuk kegitan budidaya. Sebanyak 92% masyarakat desa ingin mengimplementasikan sistem pertanian hidroponik di lahan pekarangan. Selain itu, masyarakat juga mendapat pengetahuan dalam pemanfaatan limbah pertanian sebagai pupuk organic cair dan biopestisida guna mendukung ketahanan pangan rumah tangga. https://drive.google.com/file/d/1woPpP6aJ5NCoFBtfzIMbmv0tda9HLTpD/view?usp=sharing
