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: Hama dan penyakit tanaman terung (Solanum melongena L.) di Kecamatan Rancabungur, Kabupaten Bogor
Abstrak: Eggplant (Solanum melongena L.) is a vegetable crop that quite common cultivated in Indonesia. The consumption level of eggplant increases from year to year. There are few information on pests and diseases of the crop in Indonesia. However, pests and diseases become potentially problem in the future when the crop is grown widely. The objective of this research was to obtain information about pest and disease occurrences found in eggplant growing area in Rancabungur their population or damage level. The research method included observation, sampling of the pests and diseases at two eggplant areas, and laboratory identification of the causal agents. The eggplant vegetative and generative growth phases were observed in the same area and period of time. There are some pests found predominantly in eggplant at high population i.e. Empoasca sp. (Hemiptera: Cicadellidae) and Epilachna sp. (Coleoptera: Coccinellidae), whereas Valanga sp. (Orthophtera: Acrididae) (low population), Acherontia sp. (Lepidoptera: Sphingidae), Bactrocera spp. (Diptera: Tephritidae), Mictis longicornis (Hemiptera: Coreidae), and Aulacophora sp. (Coleoptera: Chrysomelidae) were at low population. Eggplant’s diseases found at high incidence in the area were fruit rot (Phomopsis sp.) and anthracnose (Colletotrichum sp.), whereas leaf spot (Alternaria sp.) and bacterial wilt (Ralstonia solanacearum) were at low incidence. All of those pests and diseases, except Bactrocera spp., caterpillar, fruit rot, and anthracnose found at both growth phase of the plant. Fruit rot, and anthracnose were the most important diseases of eggplant at generative phase with the intensity about 47.09% and 40.84%.

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.
