Abstrak: Eggplant is one of the most wanted vegetables in Indonesia, even the world. It contains antioxidants which can be used to prevent periodontic disease. It also contains vitamin A and B, and it is good to be consumed by diabetics. Among many diseases in eggplant, fruit rot is one of the major factors as a limited factor in production of this crop. The objective of this study was to observe fruit rot disease condition in subdistricts Rancabungur and Kemang, the district of Bogor. The fruit rot pathogens identified as Phomopsis vexans and Colletotrichum melongenae were covered in all observation plots. Besides of fruit, these pathogens also caused the symptom on stems and/or branches. In one symptomized plant part, these two pathogens were able to appear singly or mixed with the other. In the dry season the symptom was only detected on fruit, while in the wet season can also occurred on stems and/or branches. The disease incidence on fruit during dry season was less than 5% and in the early wet season it increased up to 8%. In wet season observation, disease severity of each plant was varied and mostly higher in the mature plants. Single observation of 20 samples on diseased branches and stems, C. melongenae dominated (80%) as the causal agent.

Judul: Survei Penyakit Keriting (Cladosporium cladosporioides) pada Tanaman Pepaya di Bogor
Abstrak: Papaya is one fruit crops which are widely grown and consumed in Indonesia. Some pests and diseases in papaya are known to be limiting factor on the papaya production. Among o the diseases existing, the new disease namely leaf curl disease caused by Cladosporium cladosporioides has been reported since 2011 in Bogor. The objectives of this survey was to determine the status of this disease in the fields and same agricultural practices that may affect its development. The survey was conducted in two subdistricts Rancabungur and Sukaraja where papaya mostly cultivated. The results showed that leaf curl disease is widely spread in those two districts as indicated by the disease incidence, the disease incidence in Rancabungur and Sukaraja was 86.7% and 95.7% respectively. However, the disease severity is still moderate with average ranging from 24.2 to 27.6%. Generally the disease incidence in moderate type (Caliporan) and monoculture cropping system was lower than the large type (Bangkok) and multiple cropping system. Meanwhile, the disease severity did not show much differences due to the fruit type and cropping system. Other cultivated practices did not show much differences effect, both to the disease incidence and severity.

Judul: Penerbangan Otomatis Pesawat Tanpa Awak Jenis Sayap Tetap dengan iNav
Abstrak: Pesawat tanpa awak (UAV) dapat dikendalikan secara manual dengan remote control atau secara otomatis dengan flight controller (FC). Salah satu jenis UAV adalah sayap tetap yang memiliki bentuk seperti pesawat terbang pada umumnya. Penelitian ini bertujuan untuk melakukan penerbangan otomatis pada UAV jenis sayap tetap dengan mengkonfigurasi perangkat FC. UAV yang digunakan adalah model SkySurfer X8 dengan bentang sayap 1.4 m. FC yang digunakan adalah Matek F405-Wing yang dikonfigurasi dengan perangkat lunak iNav. Berdasarkan hasil uji terbang, UAV berhasil terbang secara otomatis mengikuti skenario yang diberikan. Skenario terjauh berupa persegi berukuran 600×600 m pada ketinggian 100 m, yang ditempuh dalam waktu sekitar 2 menit dengan kecepatan sekitar 65 km/jam. Diharapkan prosedur perakitan, konfigurasi, operasi, dan hasil data uji terbang dapat menjadi acuan dalam penelitian selanjutnya.
