Abstract

Salak pondoh (Salacca zalacca var pondoh) is a plant native to Indonesia and this fruit has quite high value and is liked by many consumers in Indonesia. However, the quality of snake fruit can decrease due to damage caused by plant pathogens such as fungi (fungi). This of course can result in snake fruit being unfit for consumption because it is damaged. The results of the research found that there are three types of diseases that attack Pondoh salak plants which are caused by fungi, namely brown leaf spot disease caused by the fungus Pestalotia sp. with an attack intensity of 42%-54%, stem rot disease caused by the fungus Corticium salmonicolor with an attack intensity of 26%-30%, and fruit rot disease caused by the fungus Chalaropsis sp. with an attack intensity of 20% -23%. The cause of fungal disease attacks on Pondoh salak plants is also triggered by the humid environmental conditions around the Pondoh salak plantations and the rainy season, making it easier for the fungus to reproduce.

Abstract

Aphelenchoides besseyi, a nematode, can infect rice resulting in the white shoot disease, which decreases the germina-tion rate and even causes seedling death. A. besseyi has recently been reported to mainly attack the organic rice varie-ties especially Pandanwangi and Ciherang in the Pasar Kawat, Beringin District, Deli Serdang, Indonesia. This research investigated A. besseyi via morphological, molecular, and morphometric approaches. The nematodes were observed in an area of 2000 m2, divided into five sample plots each with an area of 400 m2 on which Pandan Wangi and Ciherang rice were cultivated. Nematode morphology was observed using a stereo microscope at a 10–100x magnification. Mo-lecular identification employed PCR, followed by sequencing and phylogenetic analysis. This nematode possessed typ-ical morphological characteristics namely a longer female body (457.07–738.86 µm) than males (385.23–505.29 µm), and cured spicules, 17 to 21 µm long. The tail was ribbon-shaped with a tapered tip that had a mucrone with 2–4 points. Sequencing and phylogenetic analysis revealed that A. besseyi isolated from Indonesia (Deli Serdang/North Sumatra) was closely related to those from China, India, Russia, Taiwan, and Portugal with a 98% homology level.

Abstract

Parmarion martensi is a major pest of cabbage crops, causing damage that reduces both quality and market value. The use of botanical pesticides as an alternative control method has not been widely studied. This study aimed to evaluate the effectiveness of extracts from Aegle marmelos (maja fruit), Azadirachta indica (neem leaves), and Carica papaya (papaya leaves) in controlling P. martensi. The experiment was conducted using a Completely Randomized Design (CRD) with 11 treatments and 3 replications. Treatments included a negative control (A0), synthetic pesticide (A1), and plant extracts at concentrations of 20%, 25%, and 30% (A2–A10). The results showed that neem leaf extract at 30% (A7) produced the highest mortality rate, reaching 93.3% at 5 days after application (DAA), with an average feed consumption of 0.39 g/day. Probit analysis indicated an LC₅₀ of 20.3% and an LT₅₀ of 3.6 days, suggesting a strong toxic effect. These findings indicate that neem leaf extract at 30% concentration has potential as a botanical molluscicide to replace chemical pesticides.

Abstract

This study aims to determine the effectiveness of lemongrass (Cymbopogon nardus) extract, noni leaves (Morinda citrifolia), and papaya leaves (Carica papaya) in suppressing the population of maize weevil pests (Sitophilus zeamais) during maize seed storage. The research was conducted at the Organic Chemistry Laboratory of the University of North Sumatra using a Completely Randomized Design (CRD) with 10 treatments and 3 replications. The data were analyzed using ANOVA and further tested with the DMRT at 5%. The results showed that the treatments had a significant effect on the mortality of S. zeamais (p 0.05). The highest mortality (65%) was obtained from the treatment of 15 g noni leaves and 15 g lemongrass per 100 g of maize seeds, whereas the control was only 7.5%. This effectiveness is related to bioactive compounds such as saponins, flavonoids, and citronellal, which are toxic to insects. These results indicate the potential use of local plant extracts as environmentally friendly botanical pesticides for controlling storage pests and maintaining the quality of corn seeds.

Abstract

Artikel ini bertujuan untuk mengetahui inventarisasi penggunaan pestisida pada budidaya cabai merah di wilayah Kecamatan Berastagi. Budidaya cabai merah (Capsicum sp.), komoditas bernilai ekonomi penting di Karo – khususnya Kecamatan Berastagi, tetap mengandalkan sistem konvensional yang rawan serangan hama dan penyakit. Penelitian dilakukan November 2024–Januari 2025 dengan 30 responden petani (metode purposive sampling). Data dikumpulkan melalui wawancara menggunakan kuesioner yang mencakup karakteristik petani, jenis dan frekuensi penggunaan pestisida, pengetahuan tentang produk, serta praktek aplikasi. Hasil menunjukkan bahwa sebagian besar petani (53,33 %) menggunakan insektisida, sedangkan 46,67 % menggunakan fungisida. Praktik pencampuran larutan (tank-mix) dilaporkan 53,33 % petani, waktu aplikasi dominan pagi (60 %), dan frekuensi aplikasi mayoritas dua kali seminggu (50 %). Pengetahuan mengenai teknis aplikasi (seperti penyemprotan dua kali seminggu, di luar ruangan, sesuai arah angin dan cuaca baik) menunjukkan tingkat “tinggi” (antara 74–90 %), namun pengetahuan tentang legalitas dan risiko pestisida kadaluarsa relatif “cukup” (54–62 %).

The study was conducted This study was conducted in the oil palm plantation at PTPN IV Tanah Raja which is located in two (2) sub-districts, namely Sei Rampah Sub-district and Teluk Mengkudu Sub-district, Serdang Berdagai Regency with a distance of ± 56 km from Medan city and ± 30 km from Tebing Tinggi which was carried out in Afdeling V in July - August 2024. The study is a type of quantitative descriptive research, namely by using survey and experimental methods. The results of the study show that the yellow light can catch 159 individuals/plot, the white light obtained the number of imago catches of 64 individuals/plot, while the use of green light color 0 individuals/plot. To see the difference in the number of bagworm imago catches, a t-test with two paired samples was carried out. The t-test results showed a t-value of 10.46 greater than the t-table of 2.78 with a significance value of 0.000 0.05, so the number of catches in the yellow light was significantly more than the white light. It can be concluded that yellow light can be used as an effective catcher in controlling the bagworm population in oil palm plantations.

Abstract

The aim of this study was to observe the effect of various vegetable insecticide extracts on controlling armyworm (Spodoptera litura) on soybean plants in the laboratory. The research was conducted at the Plant Protection Laboratory, Faculty of Agriculture, University of Medan Area, from November 2021 to April 2022, using a Completely Randomized Design (CRD) Non Factorial, consisting of 7 treatment levels, namely: N0 = no treatment (control), N1 = Mindi leaf extract concentration 5% (50 m/l water), N2 = Mindi leaf extract 10% (100 ml.l water), N3 = Mindi leaf extract concentration 15% (150 m/l water), N4 Babadotan concentration 5 % (50 ml/l air), N5 = 10% concentration of Babadotan leaf extract (100 ml/lair), N6 = 15% concentration of Babadotan leaf extract (150 ml/lair), with repetition 3. Parameters observed for Armyworm Mortality (%), LC50, LT50, the proportion of the effectiveness of vegetable insecticides on armyworm mortality and the amount of feed consumed. The results showed that the application of vegetable insecticides had a significant and very significant effect on armyworm mortality from 4 days after application to 10 days after application with the highest mortality proportion at a concentration of 15%. The LC50 values of the plant insecticides mindi leaves and babadotan leaves were almost the same, namely 4.69 and 4.48%. The LT 50 value for a concentration of 15% showed that babadotan leaf extract was faster than mindi leaf extract, namely mindi leaves 5.145 days and babadotan leaves 4.633 days. Concentrations of 10 and 15 % of the 2 plant extracts tested showed the same effectiveness on mortality of S. litura caterpillars and higher dissolving concentrations of 5%. The amount of feed consumed was also significantly different with the highest amount of feed in the control treatment (60.75 g) followed by the treatment of mindi leaves and babadotan leaves at concentrations of 15, 10, and 5%.

Abstract

This study aimed to evaluate the growth and yield responses of soybean (Glycine max L. Merr.) to the application of liquid organic fertilizer (LOF) derived from apu-apu (Pistia stratiotes L.) and various soil conditioners on Ultisol soil. The research was carried out from September to December 2020 at the experimental garden of the Faculty of Agriculture, Universitas Medan Area, located at an altitude of 22 masl with flat topography, Ultisol soil characteristics, and a soil pH of 4.94. The experimens used a randomized block design with two factors: (1) concensrations of apu-apu LOF (0%, 25%, 50%, and 75% per liter of water) and (2) types of soil conditioners (no conditioner, rice-husk biochar, Mucuna bracteata green manure, and human-hair organic amendmens at 50 g per polybag). Observed parameters included plans height, number of branches, flowering age, number of bunches per plans and per plot, number of pods per plans and per plot, seed weight per plans and per plot, and 100-seed dry weight. The results showed that the application of LOF from apu-apu significansly increased several agronomic and yield componenss, namely number of branches at 6 WAP, number of bunches per plans and per plot, number of pods per plans and per plot, seed weight per plans and per plot, and 100-seed dry weight. Meanwhile, the application of differens soil conditioners produced highly significans effects on plans height at 4–6 WAP, number of pods per plant and per plot, seed weight per plans and per plot, and 100-seed dry weight, although it did not significansly affect the number of branches or number of bunches. Overall, the combination of LOF and soil conditioners improved soybean growth and productivity in Ultisol soil conditions.
