Abstract

ECO-FRIENDLY PEST MANAGEMENT İN TANJUNG SELOR REGİON. Pest control in the most parts of the Republic of Indonesia still relies on the application of synthetic chemical insecticides, including the Tanjung Selor area. Tanjung Selor is the administrative center or capital of the province of North Kalimantan. This sub-district located in Bulungan Regency, North Kalimantan Province, Indonesia with the majority of the population working as farmers. The unwise use of synthetic chemical insecticides by farmers has a negative impact on many aspects. Therefore, it is necessary to socialize about environmentally friendly pest control. This activity begins with a preliminary survey in order to determine the respondents and the efficiency of the implementation of the next activity. After that, the activities were socialization and ended with an evaluation to determine the effect of the activities. The activities have a positive influence on the knowledge and actions of farmers on environmentally friendly pest control. Prior to the activity, only 27% of farmers knew about it and 10% carried out environmentally friendly pest control. However, three months after the activity, these two figures increased to 40% and 15%.

Abstract

Intercropping is acknowledged as an effective agricultural intensification strategy for limited land. Planting time is an important factor in intercropping systems because it may intensify canopy overlap and shading, particularly because both crops rely on the C3 photosynthetic pathway, potentially reducing growth and yield. This study examined the effect of different planting times for cucumber (Cucumis sativus L.) and peanut (Arachis hypogaea L.). The study was conducted from October 2023 to February 2024 with a one-factor randomized block design. Five treatments were applied: simultaneous planting and cucumber planting at 1, 2, 3, and 4 weeks after peanuts, each replicated five times. Several data were analyzed using analysis of variance (F-test), followed by Tukey’s HSD test at the 5% significance level. This study confirms that differences in planting time between cucumbers and peanuts significantly affect soil macronutrient dynamics, growth and production, and land use efficiency. Soil macronutrient analysis showed that simultaneous planting (P1) resulted the highest soil nitrogen increase (0.38%). However, this treatment also caused a reduction in phosphorus to 15.15 mg per 100 g of soil and potassium to 13.48 mg per 100 g of soil. In contrast, excessive delay (P5) caused nitrogen to drop to 0.11% and phosphorus to decline to 14.19 mg per 100 g soil, despite potassium remaining relatively high (17.87 mg per 100 g of soil). Simultaneous planting produced the highest vegetative growth of cucumber, with an average of 40.68 leaves per plant, the greatest fruit length (22.16 cm), individual fruit weight (414.55 g), and total fruit weight per plant (2498.39 g). Delaying cucumber planting resulted in the lowest value of 828.45 g in P5. The highest pod weight was recorded in P1 at 62.46 g per plant. In contrast, planting cucumbers one week after peanuts (P2) resulted in the lowest peanut yield, at only 47.14 g per plant. All treatments achieved LER values greater than 1, confirming the superiority of intercropping over monoculture. The highest LER was obtained in P1 (1.61). In conclusion, simultaneous planting of cucumbers and peanuts provides the most optimal balance between soil nutrient utilization, crop growth, yield, and land use efficiency. Therefore, synchronized planting time is a key management strategy for improving productivity and sustainability in cucumber–peanut intercropping systems under limited land conditions.

Abstract

The root-knot nematodes Meloidogyne incognita poses a serious threat to horticultural food and plantation crops. One of the effective and efficient measures to overcome this nematode is using bacteria as a biological control agent. This study aimed to test the effectiveness of Bacillus subtilis bacteria grown on media with additional micronutrients as a biological control agent for M. incognita. The test was carried out by growing bacteria in 100 mL of nutrient broth (NB) added with FeCl2, MnCl2, and CuCl2. Each type of micronutrient was administered at concentrations of 35 ppm, 40 ppm, 45 ppm, 50 ppm, and 55 ppm. As a control, NB media was used without the addition of micronutrients. The test results showed that the best performances on bacterial growth were 55 ppm MnCl2, 45 ppm MnCl2, 40 ppm MnCl2, 40 ppm CuCl2, 50 ppm MnCl2, and 35 ppm MnCl2. These six treatments were then used in an antagonism test. A total of 150 J2 M. incognita in 4 mL of suspension was put into a petri dish with a diameter of 5 cm. After that, 1 mL of each bacterial suspension was put into a petri dish following the treatment. The mortality rate of M. incognita in each treatment was 77.5% in 55 ppm MnCl2, 74.5% in 45 ppm MnCl2, 77.25% in 40 ppm MnCl2, 73.25% in 40 ppm CuCl2, 78.75% in 50 ppm MnCl2, 79% in 35 ppm MnCl2, and 53.25% in control. The same six treatments were also used to measure the chemotaxis index of M. incognita on tomato roots. Tomato seeds of the Tantyna variety were soaked for 60 minutes in a bacterial suspension grown on micronutrient-enriched media. After seven days, the tomato seed roots were removed and placed in 5 mL 20% Pluronic F-127 Gel which had been infested with 100 J2 M. incognita. After 6 hours, the number of nematodes approaching the roots was observed. The chemotaxis index in the treatments ranged from 16% to 24%, while that in the control was 33%. This study corroborates that the addition of micronutrients MnCl2 and CuCl2 to the growth medium of B. subtilis can increase antagonistic activity against M. incognita and suppress its chemotaxis response in tomato roots soaked in the bacterial suspension.

Abstract

Mealybug infestations are a growing concern in tropical horticulture due to their rapid population increase and the significant damage they cause to fruit crops. This research examined the severity of attack and population density of mealybugs (Pseudococcidae) on papaya (Carica papaya L.), and analysed their relationship with environmental conditions and cultivation practices in several locations in Tarakan City, North Borneo. The study was conducted from January to April 2025 at seven papaya cultivation sites, including Juata Laut 1–5, Juata Permai, and Karang Harapan. A field survey combined with purposive sampling was applied to assess a minimum of 100 papaya trees over one year old at each site. Data collected included the number of infested trees, mealybug population per plant, types of fertilizers and pesticides used, plant age, and surrounding land conditions. The percentage of trees infested with mealybugs ranged from 25.07% to 38.89%, while the average mealybug population on infested trees ranged from 199.52 to 224.59 individuals per plant. Sites characterized by intensive application of chemical fertilizers and pesticides—such as Juata Laut 2 and Juata Laut 4—showed higher infestation levels than those managed with organic practices, such as Juata Permai. Environmental factors, particularly high humidity and inadequate drainage, were also associated with increased mealybug population growth. These findings indicate that environmental conditions and cultivation techniques play a substantial role in shaping the population dynamics of mealybugs. The results highlight the importance of implementing Integrated Pest Management (IPM) strategies that emphasise ecological approaches and environmentally sustainable cultivation practices to mitigate mealybug infestations in humid tropical regions such as Tarakan City.
