Pengaruh Konsentrasi dan Waktu Aplikasi Giberelin terhadap Pertumbuhan dan Hasil Tanaman Melon (Cucumis melo L.)

Elfira Rizki Oktaviana Fasya, Ramdan Hidayat, Pangesti Nugrahani — Sun, 30 Nov 2025 00:00:00 +0000

Melon (Cucumis melo L.) is a horticultural variety widely cultivated in Indonesia due to its sweet taste, nutritional content, and high economic value. This study aimed to determine the optimal concentration and application timing of gibberellin (GA₃) to enhance the growth and yield of Fujisawa melon plants. The research was arranged in a factorial design using a Completely Randomized Design (CRD) with two factors and four replications. The first factor was gibberellin concentration (0, 50, 100, and 150) ppm, and the second factor was application timing (pre-anthesis, anthesis, and post-anthesis stages). The results showed a significant interaction between gibberellin concentration and application timing on fruit volume. The single treatment of 100 ppm GA₃ had the best effect on plant height, harvest time, and number of fruits formed.

Analisa Keputusan Petani dalam Penggunaan Pestisida untuk Pengendalian Hama dan Penyakit Tanaman Tomat (Solanum lycopersicum)

Dwi Haryanta, Achmadi Susilo, Bagas Tri Prayogo — Sun, 30 Nov 2025 00:00:00 +0000

Penggunaan pestisida yang kurang tepat oleh petani merupakan isu kritis yang dipengaruhi oleh faktor-faktor psikologis, perilaku, sosial ekonomi, dan regulasi. Tujuan penelitian adalah untuk menganalisis proses pengambilan keputusan petani dalam menggunakan pestisida untuk mengendalikan hama dan penyakit tanaman tomat. Penelitian kuantitatif diskriptif dengan kuesioner disusun berdasarkan lima dimensi persepsi petani tentang keberadaan hama dan penyakit tanaman tomat dan cara pengendaliannya meliputi: (1) Persepsi petani terhadap keberadaan hama dan penyakit (X1), (2) Persepsi petani terhadap terjadinya kerusakan pada tanaman (X2), (3) Persepsi petani terhadap terhadap Teknik pengendalian hama dan penyakit (X3), (4) Persepsi petani terhadap penggunaan pestisida (X4), dan (5) Persepsi petani terhadap efek negatif pestisida (Y). Temuan penelitian adalah para petani tomat mengetahui adanya hama dan penyakit yang menyebabkan kerusakan pada tanaman tomat. Oleh karena itu diperlukan tindakan pengendalian dan yang paling praktis adalah dengan menggunakan pestisida. Para petani mengetahui dan menyadari bahwa penggunaan pestisida berdampak negatif terhadap lingkungan dan kesehatan konsumen. Kesimpulan penelitian adalah petani tomat selalu menggunakan pestisida (insektisida dan fungisida) untuk mengendalikan hama dan penyakit agar mendapatkan hasil panen yang dapat dijual di pasar. Keselamatan konsumen dan kelestarian lingkungan belum menjadi menjadi pertimbangan dalam penggunaan pestisida. Perlu mendapatkan perhatian bagi penyusun kebijakan khususnya dari Dinas Pertanian untuk mensosialisasikan dan menyelenggarakan pelatihan kepada petani akan Teknik pengendalian hama yang aman dan berkelanjutan. Penggunaan pestisida seharusnya menjadi langkah terakhir dalam pengendalian hama dan penyakit.

This study evaluated land suitability for sengon (Paraserianthes falcataria) plants by utilizing soil physicochemical parameters and Geographic Information System (GIS) technology. The criteria analyzed included soil pH, organic carbon, texture, Cation Exchange Capacity (CEC), and base saturation. Sampling was conducted purposively in three land use types, namely rice fields, gardens, and dry fields. The analysis results showed that most of the land in the study area was classified as Very Suitable (S1) and Moderately Suitable (S2). The main limiting factor identified was the relatively low soil pH, especially in rice fields. Overall, the soil has a clay texture that is good at storing water and nutrients, and is supported by organic carbon and CEC values that are included in the S1 class. Thus, it can be concluded that the general condition of the land has met the criteria to support sengon growth, with recommendations to improve the acidity level (pH) of the soil to achieve optimal productivity.

Aplikasi Kombinasi Pupuk Kiserite dan Pupuk NPK Terhadap Nisbah Dispersi Tanah Pada Pertanaman Jagung (Zea mays L.), Bandar Lampung

Sun, 30 Nov 2025 00:00:00 +0000

Changes in corn production are related to the decline in agricultural land quality. One of the main indicators for assessing soil aggregate stability is the dispersion ratio. The efforts made in this study were the application of Kieserite and NPK fertilizers. This study aimed to determine the effect of the combination of Kieserite and NP K fertilizers on the soil dispersion ratio in corn crops, as well as to determine the best combination dose. The study was conducted in Campang Raya, Bandar Lampung from August 2024–May 2025 using a Randomized Block Design (RAK) with four treatments and six replications, namely A = Control, B = Standard Fertilizer (NPK), C = 1 Kieserite + 1 NPK, and D = 1 Kieserite + ¾ NPK. The main parameter was the soil dispersion ratio, with supporting parameters in the form of microaggregate distribution, soil texture, pseudo sand, soil pH, and corn production. The results showed that all treatments still produced the "highly dispersed" category (65.83–73.42%), with the lowest value in treatment C and the highest in the control. Combination of Kieserite + NPK application did not significantly improve the dispersion ratio or microaggregate distribution, but did affect corn production. Treatment C resulted in dry corn kernel production of 2.37 tons ha⁻¹, higher than the control at 1.47 tons ha⁻¹. This increase in corn production is supported by the role of Mg²⁺ ions from kieserite which can improve photosynthesis efficiency, chlorophyll formation, and transport of photosynthesis products to the cob. Magnesium fertilization in the soil plays an important role in stimulating plant metabolism, improving the quality and quantity of harvests, and the supply of NPK nutrients that stimulate root growth and root exudates to aid aggregation.

Kajian Aplikasi Kompos Sampah Organik Perkotaan untuk Tanaman Bawang Merah pada Sistem Urban Farming

The problem of accumulating organic waste can be solved by converting it into compost and can be used to strengthen food security in urban areas. The purpose of this research is to find a solution to the problem of urban organic waste burden into an economically valuable resource by processing it into compost, studying the effect of urban organic waste compost on the growth and yield of vegetable plants (shallots), and providing a fertile and affordable planting medium, reducing dependence on conventional fertilizers that must be imported from outside the city. Research on the application of compost produced from a compost house for shallot plants with 4 treatments: pure soil planting medium, soil planting medium plus leaf compost, soil planting medium plus young coconut fiber compost, and soil planting medium plus rain tree leaves. The study used a randomized block design with seven replications. The results of the study were that the best growth and yield of shallot plants were obtained from plants planted in soil media without being mixed with compost, while the worst were from plants planted in soil media with fresh rain tree leaf compost. The conclusion of the study was that the compost used was not yet mature because the composting process was only 28-35 days, or with rain tree leaves without a composting process. The use of immature compost or organic material that has not fully decomposed will actually have a negative impact on plants. Plants and microbes compete for nutrients or plants can be poisoned by compounds produced by the composting process (such as ammonium compounds). The implication of this research is that compost utilization will have a positive impact when the compost is fully mature. Compost producers, such as compost houses or recycling centers (PDU) in Surabaya, should release mature compost or socialize to the public that compost produced from compost houses needs to be incubated for at least 30 days before it can be used for urban farming activities.
