“…Salah satu bahan alam yang memiliki senyawa tersebut adalah paitan (Tithonia diversifolia), terutama bagian daun (Ramadhani et al, 2020). Beberapa aktifitas yang dimiliki oleh ekstrak daun paitan, di antaranya adalah meningkatkan mortalitas ulat bawang (Spodoptera exigua Hubn) (Hartini et al, 2022), berpengaruh terhadap mortalitas berbagai fase umur keong mas (Wicaksono et al, 2019), larva Spodoptera litura F (Sapoetro et al, 2019), penggunaan pestisida daun paitan berpengaruh terhadap produktivitas tanaman brokoli ((Brassica oleraceae L.) (Jayati & Nopiyanti, 2020). Daun paitan juga telah diteliti dapat digunakan sebagai insektisida alami, seperti untuk ovisida dan insect growth regulator (Salsabila et al, 2021).…”

The paitan plant (Tithonia diversifolia) contains alkaloids, saponins, flavonoids, tannins and phenolics which have the potential to prevent Dengue Hemorrhagic Fever (DHF). This plant also has various insecticidal activities. In society, there are many mentions of the paitan plant, so people need to know the characteristics of this paitan plant. The aim of this research is to determine the morphological characterization and specific fragments of the paitan plant, as well as to determine the activity and effective concentration of the ethanol extract of paitan leaves as a repellent for the Aedes aegypti mosquito. Two types of methods were used, namely descriptive qualitative for observing morphology, specific fragments, pollen, and phytochemical screening, and experimental methods for mosquito repellent testing, and calculating the protective power of the ethanol extract of paitan leaves. The results obtained are flowers consisting of two shapes, namely ribbon flowers in the outer circle, infertile, and tube shapes in the inner circle. Stomata are anomocytic type, while trichomes are non-glandular multicellular type. Pollen characteristics, namely small size, colpate, number 3, aperture shaped trizonocolpate with echinate ornamentation. The screening results for the ethanol extract of paitan leaves were positive for containing metabolite compounds, such as flavonoids, alkaloids, tannins, saponins, terpenoids and phenolics. The results of the mosquito repellent test showed that the higher the concentration of the extract, the fewer mosquitoes that landed. Calculation of protective power shows that the most effective concentration in repelling mosquitoes is 15%, namely 93.64%. The conclusion is that paitan (Tithonia diversifolia) leaf extract has potential activity as a repellent against Aedes aegypti mosquitoes with the most effective concentration being 15%.

“…Kipahit yang memiliki bau yang menyengat, berpotensi untuk dimanfaatkan sebagai penolak hama (repellent), salah satunya sebagai penolak hama bubuk pada jagung (Gitahi, et al, 2021). Pemanfaatan kipahit sebagai pestisida nabati juga dilakukan untuk pengendalian penyakit patik pada tembakau (Apriyadi et al, 2013), pengendalian hama keong mas pada padi (Wicaksono et al, 2019), dan sebagainya.…”

Kutu putih merupakan salah satu hama penting pada pepaya. Pengendalian menggunakan pestisida nabati diasumsikan dapat menurunkan serangan hama tersebut. Penelitian bertujuan untuk mengetahui dosis efektif ekstrak daun suren dan ekstrak daun kipahit dalam mengendalikan hama kutu putih pada pepaya. Penelitian dilakukan di Laboratorium Hama dan Penyakit Balai Penelitian Tanaman Buah Tropika pada bulan Januari – Februari 2020. Penelitian disusun menurut Rancangan Acak Lengkap dengan 5 Perlakuan dan 6 ulangan, setiap ulangan terdiri dari 10 ekor kutu putih. Perlakuan adalah dosis ekstrak daun suren, dan ekstrak daun kipahit yaitu : A= 1 ml/l, B=2,5 ml/l, C=5 ml/l, D=10 ml/l dan E=kontrol. Serangga yang diuji adalah Kutu putih instar 3 yang dikoleksi dari tanaman pepaya. Peubah yang diamati terdiri dari persentase mortalitas, laju mortalitas kutu putih, dan LC-50. Hasil analisis probit menunjukkan bahwa ekstrak daun suren pada dosis 1 ml/l sudah dapat membunuh hama kutu putih pada pepaya sampai 50%. Ekstrak daun suren mampu meningkatkan mortalitas hama kutu putih pepaya pada dosis rendah dan waktu yang cukup singkat. Ekstrak daun kipahit menekan populasi pada dosis yang lebih tinggi dan waktu yang lebih lama. Rekomendasi dari hasil penelitian, agar pada penelitian selanjutnya dilakukan pengujian langsung terhadap dosis efektif ekstrak daun suren dan ekstrak daun kipahit di lapangan.

Intensive agricultural land with a limiting factor of acidity often has a great degree of phosphate elements but is not accessible to plants. The utilization of bio-phosphate fertilizer (Bio-P) is an effort to enhance the available P for plants to support sustainable agricultural development. This research evaluated the effectiveness of Bio-P on the growth performance and production of irrigated lowland rice. The research was accomplished in Gemolong District, Sragen Regency, Central Java, Indonesia, from May to October 2021. The research was set in a randomized block design corresponded of ten treatments and four replications. The treatment corresponded of fertilization according to the recommended dose, fertilization according to the recommended dose + Bio-P, existing farmers' fertilization + Bio-P, and without fertilization. The data observed included plant growth, yield components, production, and agronomic and economic feasibility assessments. The findings revealed that fertilization treatment according to the recommended dose + Bio-P and the existing farmers' fertilization + Bio-P did not significantly affect plant growth and yield. The extension of 10 kg ha-1 Bio-P with existing farmers' fertilization produced the highest effectiveness value of 3.56 with a profit of IDR 25,400,400 ha-1 and the highest RAE value of 110.25%.
