Full text linkNational food needs to focus on the agricultural sector. Tomato production in Indonesia is still low compared to other countries. This research aims to determine the impact of using husk ash and various types of compound fertilizers on the growth and yield of tomato plants. This study was conducted at KP2 INSTIPER Maguwoharjo, Special Region of Yogyakarta, in April-July 2023. This research used a Completely Randomized Design (CRD) composed of 2 factors. The first factor is the dose of husk ash, which consists of 3 levels, namely: 50g/polybag (control), 60g/polybag, and 70g/polybag; the second factor is the type of compound fertilizer, which consists of 3 types, namely; NPK 15:15:15, NPK 16:16:16, and NPK 9:25:25 at a dose of 10g/plant. Based on these two factors, 9 treatment combinations were obtained, each repeated 3 times, so there were 27 experimental plants. The research data was analyzed using variance with an actual level of 5%. The analysis results show an interaction between abusekam and compound fertilizer on the parameters of fruit diameter, average fruit weight, fresh shoot weight, and root fresh weight. Application of husk ash at a dose of 60g and NPK 15:15:15 gave a fruit diameter of 46.33 mm. Giving 70g of husk ash affects plant growth, fruit number, and fruit/plant weight. Providing NPK16:16:16 compound fertilizer has a good effect on plant growth, fruit number, and fruit/plant weight.Kebutuhan pangan nasional menumpukan harapan pada sektor pertanian, produksi tomat di Indonesia masihlah rendah bila dibandingkan negara lain.

Indonesia Respons Pertumbuhan dan Hasil Tanaman Tebu (Saccharum officinarum L) Ratoon 2 Terhadap Kombinasi Zeolit dan Persentase Pupuk N: Tebu, Keprasan, Zeolit, Pupuk Nitrogen
No full textSugarcane (Saccharum officinarum L.) is a plant that is cultivated to be processed into sugar. However, until now Indonesia has become a sugar importing country because the sugar industry is unable to meet the needs and demand for sugar which continues to increase as well as the high domestic selling price, so that it is necessary to import sugar to meet the demand for sugar in Indonesia. To overcome this is to apply Nitrogen fertilization on sugarcane combined with a companion material in the form of Zeolite. This study aims to obtain the growth and yield of ratoon 2 sugarcane plants by administering Zeolite and the proportion of N fertilizer as well as the interaction between the Zeolite and the proportion of N fertilizer. This study used a Randomized Block Design (RAK) Arranged in a split plot with two treatment factors repeated 3 times with 6 treatment combinations to obtain 18 experimental units. The main plot of Zeolite dosing with Z₀ is without zeolite and Z₁ is 700 kg.ha⁻¹ (equivalent to 0.8 kg.8m kairan⁻¹). Subplot dosage proportions of N fertilizer with P₁ is 100% urea (equivalent to 0.36 kg. 8m caustic⁻¹), P₂ is 80% urea (equivalent to 0.28 kg. 8m caustic⁻¹), and P₃ is 60% urea (equivalent to 0.21 kg. 8m caustic⁻¹). The results of this study indicate that the dose of Zeolite has an effect on all variable parameters of growth observations which include plant height, stem diameter, and number of internodes. As well as plant yields which include stem weight, stem length, brix value and yield. Application of [dose percentage of N fertilizer did not affect the growth and yield of sugarcane plants. There was no interaction between the Zeolite dosage and the proportion of N fertilizer doses on the growth and yield of sugarcaneTebu (Saccharum officinarum L.) adalah tanaman yang dibudidayakan untuk diolah menjadi gula. Namun, sampai saat ini Indonesia menjadi negara pengimpor gula karena tidak mampunya industri gula memenuhi kebutuhan dan permintaan gula yang terus meningkat serta tingginya harga jual dalam negeri, sehingga diperlukan impor gula untuk memenuhi kebutuhan gula di Indonesia. Untuk menanggulangi hal tersebut adalah dengan melakukan pemupukan Nitrogen pada tanaman tebu yang dikombinasikan dengan bahan pendamping berupa Zeolit. Penelitian ini bertujuan untuk mendapatkan pertumbuhan dan hasil tanaman tebu ratoon 2 dengan pemberian Zeolit dan persentase pupuk N serta interaksi antara Zeolit dan persentase pupuk N.

Perkembangan Penyakit Busuk Batang pada Kelapa Sawit Pasca Peremajaan Tanaman
Full text linkBasal stem rot caused by the fungus Ganoderma boninense is the major threat to oil palm plantations in Indonesia, especially for second generation. Handling oil palm residues during the replanting process greatly determines the fungal attack. This research aims to reveal how handling oil palm trunks affects G. boninense attacks on second generation oil palm plantations. The treatments studied were felled trunk and felled-chipped trunk, each represented by two blocks (five years old of oil palm) with a density of 143 trees/hectare. The results of the study showed that second generation oil palms had a very high prevalence of basal stem rot disease, even though there were differences in the incidence and severity of the disease. Chipping of felled trunk residues can slow the development of the disease. Management of palm residues has a major influence on the onset of this disease in replanted oil palms.Basal stem rot caused by the fungus Ganoderma boninense is the major threat to oil palm plantations in Indonesia, especially for second generation.

Analisis Pertumbuhan dan Produktivitas Kelapa Sawit pada Variasi Kerapatan Tanam
Full text linkIn oil palm growth, planting density has a sustainable impact on its productivity. To enhance the long-term growth and production yield of oil palm, it is crucial to consider the establishment of appropriate planting densities during the initial planting phase. This research explores the relationship between planting density and productivity, highlighting the importance of determining optimal plant densities for optimal yields. The study was conducted at the Muara Tawang Estate (MTNE) in Kapuas Hulu Regency, West Kalimantan Province. Two blocks of oil palm land with three different planting densities (130, 136, and 143 plants per hectare) were observed to understand the relationship between planting density and agronomic characteristics. Measurements were taken on plant height, frond length, petiole width, number of male and female flowers, and sex ratio. The analysis unveiled consistent trends in oil palm production, which varied based on planting density. Planting densities of 130 and 136 showed superior production trends compared to 143, with 136 demonstrating production increases ranging from 19.8% to 29.8% relative to density 143, alongside enhancements in plant height and frond length by 4.6% and 5.4%, respectively. Additionally, petiole thickness and width were notably lower in density 143, experiencing reductions of 8.0% and 11.0%, respectively, compared to density 136, while the sex ratio exhibited a similar pattern, declining by 34.0% in density 143 compared to 136. This highlights the importance of determining appropriate planting densities to enhance oil palm productivity.In oil palm growth, planting density has a sustainable impact on its productivity.
