Hasil penelitian memperlihatkan bahwa (1) Program IPTEKMAS adalah bentuk komunikasi inovasi dengan menyebarluaskan informasi dan teknologi di bidang pengolahan hasil perikanan. Teknologi tersebut dapat diterima dan diterapkan oleh masyarakat karena memiliki atribut-atribut inovasi seperti : memiliki keuntungan relatif, keserasian, tidak rumit, dapat dicoba dan dapat diamati (2) Jumlah penerap pada saat adopsi adalah 11 orang dan bertambah menjadi 15 orang pada saat sesudah adopsi. Penerap didominasi oleh ibu rumah tangga yang telah memiliki usaha pengolahan hasil perikanan secara tradisional sebelum menerapkan teknologi program IPTEKMAS. Terjadi peningkatan pengetahuan tentang pengolahan hasil perikanan dan juga memberikan peluang usaha pengolahan yang berdampak pada peningkatan pendapatan rumah tangga (3) Bentuk jaringan komunikasi yang terbentuk pada saat adopsi dan sesudah adopsi ada 2 bentuk yaitu bentuk bintang yang saling mengunci dan bentuk roda/radial. Nilai struktur komunikasi yang diperoleh pada setiap level (individu, klik dan sistem) pada saat adopsi dan sesudah adopsi tidak jauh berbeda. Hal ini dikarenakan jumlah anggota jaringan yang masih sedikit.

Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
