Abstract

Sistem pertanian budidaya di Tarakan Timur didominasi tanaman hortikultura yang rentan terhadap serangan Organisme Pengganggu Tanaman sehingga berakibat pada penurunan produksi. Salah satu OPT yang berkaitan langsung dengan budidaya hortikultura adalah gulma dengan segala jenis, dampak, dan biologinya. Oleh sebab itu perlu tindakan identifikasi. Penelitian ini bertujuan untuk melakukan identifikasi gulma dengan mengetahui spesies gulma dan spesies gulma yang dominan dimana pelaksanaan penelitian ini pada lahan budidaya tanaman hortikultura di Kecamatan Tarakan Timur. Pengambilan sampel gulma menggunakan metode kuadrat secara acak, sebanyak 50 sampel dengan ukuran petakan 1 m x 1 m. Hasil penelitian menemukan 39 jenis gulma, 24 spesies termasuk gulma golongan berdaun lebar, 12 spesies rumputan dan 3 jenis diantaranya golongan teki. Spesies gulma dominan adalah gulma Cyperus compressus dengan nilai SDR tertinggi sebesar 23,11%.

Abstract

Pakcoy merupakan jenis sayuran yang banyak dibudidayakan di Kota Tarakan. Salah satu kendala budidaya Pakcoy adalah adanya gulma meniran yang banyak tumbuh di sekitar tempat budidaya pakcoy. Salah satu cara mengendalikan gulma meniran adalah melalui penggunaan herbisida nabati yang berasal dari gulma belulang. Kandungan metabolit sekunder dari belulang mampu mengendalikan gulma meniran. Penelitian ini bertujuan untuk mengetahui pengaruh ekstrak belulang dalam mengendalikan gulma meniran pada tanaman pakcoy. Penelitian ini mengunakan rancangan acak kelompok 1 faktor, 4 ulangan, dan 6 taraf perlakuan, yaitu tanpa ekstrak belulang, ekstrak belulang 20%, 40%, 60%, 80%, dan 100%. Peubah yang diamati berupa tinggi tanaman pakcoy 1-5 MST, jumlah daun pakcoy 1-5 MST, bobot basah pakcoy 1-5 MST, tinggi gulma meniran 1-5 MST, jumlah daun gulma meniran1-5 MST, kerusakan gulma meniran 1-5 MST, bobot basah gulma meniran, bobot kering gulma meniran.  Analisis data menggunakan ANOVA dan data yang berpengaruh nyata dilanjutkan dengan uji lanjut DMRT. Hasil penelitian menunjukkan perlakuan ekstrak gulma belulang 100% mampu menurunkan tinggi gulma, jumlah daun, bobot basah dan bobot kering gulma meniran serta memberikan tingkat kerusakan daun gulma meniran paling tinggi.

Abstract

This study evaluated nano-insecticides formulated from essential oils of mint (Mentha piperita), lemongrass (Cymbopogon citratus), basil (Ocimum basilicum), and eucalyptus (Eucalyptus sp.) for controlling Sitophilus oryzae, a major pest of stored rice. Essential oils were extracted using hydrodistillation, and nanoemulsions were prepared via a low-energy method. Efficacy tests conducted at concentrations of 1–5% showed that mint and lemongrass nano-insecticides were the most effective, achieving 100% mortality at 5% concentration within 168 hours and exhibiting superior repellency (mint oil reached 100% repellency at 5%). At 5% concentration, mint oil caused 25% mortality after 24 hours, increasing to 86% by 96 hours and reaching 100% by 120 hours, while lemongrass oil induced 10% mortality at 24 hours, 76% by 96 hours, and 100% by 144 hours. Their high efficacy is attributed to bioactive compounds such as menthol and citral, which disrupt the pest’s physiological processes. In contrast, eucalyptus and basil oils demonstrated comparatively lower mortality and repellency. These results highlight the potential of mint and lemongrass nano-insecticides as eco-friendly alternatives to synthetic pesticides and provide a sustainable option for integrated pest management in stored rice.

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.
