Abstract

The seed coating technique using organomineral fertilizer aims to reduce farming costs (fertilizer and fertilizing labor) so that farmer do not need to apply fertizers except for urea fertilizer which is not contained in organomineral fertilizers. This study aims to find out the effect of coating corn seeds with organomineral fertilizer on the growth of yields and efficiency of urea fertilizer delivery on corn crops in central Lombok vertisol in June to October 2021. The field experiment using the split plot experimental design with the main plot of seed coating treatment coated with organomineral fertilizer and as a child of plot with a dose of urea fertilizer consisting of three levels, namely 200, 300 and 400 kg urea / ha. The parameters studied are Dry Brangkasan Weight, Weight 100 Grains, Seed Yield, Pipilan Dry Weight, Plant Tissue Absorption N. The results showed that coating corn seeds with organomineral fertilizer had no real effect on all parameters. While the dose of urea fertilizer has no real effect on the Weight of Dry Brangkasan (BBK), Weight of 100 Grains, Seed Shortening and a real effect on The Dry Weight of Pipilan, Uptake of N Plant Tissue and Efficiency of Absorption N. The highest Yield of Dry Weight of Pipilan is obtained from Unsalted Seeds (BTB) on the provision of urea fertilizer 300 kg / ha. The efficiency of N uptake from Unsalted Seeds and Layered Seeds increased at urea fertilizer doses of 200 kg/ha ywhich is 77.62% and 75.71%.

Abstract

Permasalahan perubahan iklim dipulau Lombok khususnya di Kabupaten Lombok Barat, hal ini menjadi faktor utama dalam melaksanakan kegiatan produksi pertanian di wilayah Kabupaten Lombok Barat. Salah satu upaya yang harus dilakukan dengan analisis tipe iklim dengan menggunakan metode Oldeman agar dapat mengetahui kebutuhan air tanaman serta curah hujan pada wilayah tersebut. Tujuan dari penelitian ini yaitu, untuk mengetahui mengetahui tipe iklim di beberapa Kecamatan di Lombok Barat berdasarkan klasifikasi iklim menurut Oldeman. Metode yang digunakan dalam peneltian ini adalah metode deskriptif, yang dimulai dengan pengumpulan data dari badan meteorologi, klimatologi dan geofisika., menganalisis data dan menginterpetasi data. Analisis tipe menurut Oldeman pada dasarnya menentukan jumlah bulan basah, bulan kering dan bulan lembab yang dimana jumlah bulan basah > 200 mm, bulan kering < 100 mm dan bulan lembab 100-200 mm. Hasil yang diperoleh dari penentuan tipe iklim pada beberapa Kecamatan yaitu pada Kecamatan Kediri bertipe iklim C3, pada Kecamatan Narmada D3, pada Kecamatan Lembar D3 dan pada Kecamatan Gerung bertipe iklim E3.

Abstract

Melaleuca cajuputi (cajuput) is a plant from the Myrtaceae family that has been widely used, especially by the essential oil industry, which contains the main compound in the form of 1.8 cineol. The research aims to understand the influence of Rootone-F hormone concentration, the effect of planting media, and the interaction between Rootone-F hormone concentration and planting medium on the growth of cajuput cuttings (Melaleuca cajuputi). The design used in this study is the completely randomized design (CRD), with factorials consisting of two factors and three replications, giving the total samples of the study of 48 treatments. The first factor is the hormone (R) consists of 4 levels, namely control 0 ppm (), 100 ppm (), 200 ppm (), and 300 ppm (). The second factor is the growing media (M) consists of 4 levels, namely soil (), soil + cocopeat (), sand + cocopeat (), and cocopeat (). The results show that the use of Rootone-F hormone and planting media have no significant effect on all research parameters (namely: seedling height, seed diameter, number of leaves, root length, and live percentage) of cajuput (Melaleuca cajuputi).

Abstract

Protected forests play a critical role in biodiversity conservation and ecosystem stability but are often threatened by exploitation. Dalbergia latifolia (sonokeling) is a high-value species experiencing population decline due to overexploitation. This study aims to analyze the potential and distribution of sonokeling in the Sejorong Mataiyang Protected Forest Block, West Sumbawa Regency. Data were collected using the n-tree distance sampling method and vegetation analysis with the Importance Value Index (IVI) to measure density, frequency, and dominance. The results show that Dalbergia latifolia dominates across all vegetation levels (seedlings, saplings, poles, trees). At the seedling and sapling levels, plot 12 recorded the highest relative density (KR) and relative frequency (FR) values, both at 27.727%. At the pole level, the highest dominance (11.048%) was found in plot 5, while at the tree level, the highest dominance value (9.128%) was recorded in plot 9. These findings highlight sonokeling’s strong regeneration and adaptability to various environmental conditions. Sonokeling holds significant potential for conservation through ecosystem-based management and protection from overexploitation. This study provides a scientific basis for conservation efforts, supporting the sustainability of local ecosystems.

Abstract

Silicate rocks, the abundant plant nutrient source in Indonesia, have not been evaluated for use as a fertilizer/and soil ameliorant. This research was aimed to identify (1) mineral and elemental compositions of silicate rocks originated from Galunggung, Kelud, Tambora, and Rinjani Volcanoes and (2) soil properties determining dissolution rate of plant nutrients from the silicate rock fertilizers (SRFs). The rocks were ground with a ball mill for 10 min providing SRFs with medians of particle size of 30 – 50 mm. Each SRF was added to 6 soils from West Java, East Java, and Lombok Island at a rate equivalent to 20 t ha-1, incubated for 28 days in a laboratory condition.  Results indicate that adding SRFs clearly increased soil pH with negligible effect on soil salinity. Adding SRFs also increased quantity of citric-oxalic-extractable plant nutrients (Ca, K, Zn, and Cu) and activity of soil micro-organisms. Dissolution of plant nutrients from the SRFs in the soils was mainly determined by combination factors of C-organic content and pH of soils before application of the SRFs. It was concluded that SRFs originated from those volcanoes may be used as a plant-multi nutrient source and a remedial agent for acidic and biologically degraded soils. However, the true effectiveness of SRFs for those uses needs to be further tested under various soil-plant systems.
