Abstract

Flower and fruit loss and low fruit quality are complex problems faced in star fruit cultivation. The research aims to determine the effect of pruning twigs and applying foliar fertilizer on plant growth, quantity and quality of fruit. Factorial research using two treatment factors. . Factor I is the type of foliar fertilizer, consisting of D0 = No foliar fertilizer (control), D1 = SB foliar fertilizer (8-20-15), D2 = HP foliar fertilizer (10-40-15), and D3 = DN foliar fertilizer (10-30-37). Factor II is the interval for applying foliar fertilizer, consisting of I1 = once every 7 days interval, I2 = once every 10 days interval, and I3 = once every 14 days interval. The research used plant material of the same age, as replications, groups of plants were used that were differentiated according to the pruning model, namely P0 = Plants that were not pruned as replication I, P1 = Plants that only had their wiwilan branches pruned as replication II, and P2 = Plants that had their branches pruned wiwilan and clustered branches (remaining the good ones) as repetition III. The results showed that application of foliar fertilizer and pruning of branches increased the number of fruit, fruit weight and size of sweet star fruit. Pruning wiwilan branches and reducing clustered branches has the greatest effect on the number of fruit, fruit weight and fruit volume compared to other pruning intensities. The research results can be used as a reference for star fruit farmers in determining maintenance actions, especially in fertilizing and pruning to regulate the canopy. while increasing production.

Abstract

Many livestock waste has not been utilized, and is even left unused, which will harm environmental health. This research aims to determine the effect of types of manure on the growth and yield of Okra plants (Abelmoschus esculantus L.), and to determine the optimum dose of each type of manure as a reference in recommendations for the use of manure for okra plants. . The single factor experiment used a randomized completly block design (RCBD) with 4 treatments repeated 5 times, namely P0 (without drum fertilizer), P1 (cow manure), P2 (chicken manure), and P3 (goat manure). The results of the research showed that cow manure gave the best results even though it was not significantly different from goat manure, with a production of 12.63 tons / hectare, while the smallest effect was even lower than the control, namely the chicken drum manure treatment. In testing manure and compost (solid organic fertilizer) the maturity level must be the same (mature) by looking at the C/N ratio value.

Abstract

The effect of seed tuber weight on the growth and production of potatoes (Solanum tuberosum L.) is intended to determine the efficiency of using tubers as seed material in potato cultivation. The single factor experiment was carried out using a randomized block design (RAK) consisting of 8 treatments, namely treatment A (Granolla variety with tuber weight 28 – 30 g), B (Granolla variety with tuber weight 31 – 45 g), C (Granolla variety with tuber weight 46 – 60 g), D HPS variety with tuber weight 31 – 45 g (Granolla variety with tuber weight 61 – 80 g), E (HPS variety with tuber weight 28 – 30 g), F (HPS variety with tuber weight 31 – 45 g), G (HPS variety with tuber weight 46 – 60 g), and H treatment (HPS variety with tuber weight 61 – 80 g). Each treatment was repeated four times. The results showed that the results were better for tubers weighing 46 - 60 g than tubers weighing 28 - 45 g, and the results were the same compared to tubers weighing 61 - 80 g, both for the HPS variety and the granolla variety. In developing potato cultivation, it is necessary to pay attention to the availability of quality seeds, the weight of the seed tubers and varieties that are suitable for the land environment. By increasing the production of quality tuber seeds, it is hoped that it can contribute to increasing productivity and potato production

Abstract

The use of pesticides is often the primary choice to protect chili pepper plants (Capsicum frutescens L.) from damage caused by pests and diseases. However, excessive and uncontrolled use of pesticides can lead to pesticide residues adhering to the chili peppers (Capsicum frutescens L.). This research is descriptive quantitative, involving a laboratory experiment that uses gas chromatography-mass spectrometry (GC-MS) to measure the amount of pesticide residues on chili peppers (Capsicum frutescens L.). The study found that insecticides with active ingredients Chlorpyrifos and Profenofos are the most frequently used by farmers, with applications occurring twice a week. The levels of pesticide residues on chili peppers (Capsicum frutescens L.) show significant variation among samples. Based on the results and discussion, it can be concluded that: the average residue level of Chlorpyrifos on chili peppers sold at Keputran Surabaya market is 3.13 ppm, while Profenofos has an average of 3.25 ppm. Furthermore, the average residue level of Chlorpyrifos in the chili pepper samples from Keputran Market in Surabaya exceeds the Maximum Residue Limit (MRL) established by the Indonesian National Standard (SNI), which is 0.5 ppm. Additionally, the average residue level of Profenofos also exceeds the established MRL, which is 2.0 ppm.

Abstract

This study aims to analyze the pesticide residue levels in tomatoes (Solanum lycopersicum) marketed at Pasar Keputran, Surabaya, and to evaluate whether the residue content exceeds the maximum permissible limit set by applicable regulations.This study employs a quantitative method with laboratory experiments using gas chromatography-mass spectrometry (GC-MS) to analyze pesticide residues. The tomato samples tested were obtained from farmers in Desa Sajen, Pacet District, Mojokerto Regency, and sold at Pasar Keputran, Surabaya. The study grouped the samples based on the frequency of pesticide spraying: no spraying, one-time spraying, and two-time spraying. The results showed that pesticide residues were present in the tomatoes, with levels increasing as the frequency of spraying increased. Samples with two-time spraying contained residues exceeding the maximum permissible limits set by food safety regulations. Statistical analysis revealed significant differences between the residue levels in the samples and the expected values, indicating potential health risks for consumers. This study also highlights the importance of strict supervision of pesticide use, especially concerning dosage and frequency of spraying, to prevent negative impacts on public health. The implementation of safer and more sustainable agricultural practices is necessary to reduce the risk of excessive pesticide exposure and to raise farmers awareness of proper pesticide use procedures in accordance with standards.

Abstract

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.

Abstract

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.
