Abstract

NOURMA AMALIA SUGIARTO. Observasi Perubahan Iklim Mikro Harian dan Perkembangan Bunga menjadi Buah Kopi Robusta (Coffea canephora). Dibimbing oleh AIDIL AZHAR. Observasi perubahan kondisi iklim mikro diurnal pada perkebunan kopi Robusta di Malang, Jawa Timur, Indonesia, dilakukan pada bulan September hingga November 2023. Pengamatan dilakukan di dua blok berbeda, Blok 1 dan Blok 2 dengan umur 35 tahun dan 89 tahun. Data iklim mikro diurnal yang diamati adalah suhu udara, kelembaban udara, intensitas cahaya, dan radiasi matahari. Selain itu, terdapat data perkembangan bunga menjadi buah kopi Robusta. Vegetasi di Blok 1 memiliki intensitas cahaya dan radiasi matahari yang lebih tinggi dibandingkan Blok 2. Tanaman kopi yang ditanam di Blok 1 dan 2 memiliki tingkat perkembangan bunga menjadi buah sebesar 56% dan 50%.

NOURMA AMALIA SUGIARTO. Observation of Microclimate Diurnal Change and Successful Rate of Robusta Coffee (Coffea canephora) Flower-to-Fruit Formation. Supervised by AIDIL AZHAR. Observation of diurnal change of microclimate conditions in a robusta coffee plantation in Malang, East Java, Indonesia, was conducted from September to November 2023. The observation was done in two different blocks, Block 1 and Block 2 with 35-year-old and 89-year-old plants, respectively. The diurnal microclimate data observed were ambient air temperature, air humidity, light intensity, and solar radiation. Apart from that, there is data on the development of flowers into Robusta coffee fruit. The vegetation in Block 1 has higher diurnal light intensity and solar radiation than in Block 2. The coffee plants grown in Blocks 1 and 2 have a 56% and 50% success rate of flower-to-fruit formation, respectively.
