Judul: Pengaruh Naungan Paranet terhadap Iklim Mikro dan Produktivitas Pucuk Tanaman Kolesom (Talinum triangulare (Jacq.)Willd.)
Abstrak: Water-leaf (Talinum triangulare (Jacq).Willd.) is one of medicinal plant which has many benefits. Part of the plant organ which often utilized is the shoot. This research, which was conducted using factor analysis of fixed model, aimed analyze the effect of paranet shading on micro climet and productivity of water-leaf’s shoot. The results showed that paranet shading had profound effects on radiation and temperature, and on growth and productivity of water-leaf. Shading using paranet 50% could reduced radiation transmission by 27%, reduced temperature by 0.3ᵒC, and reduced shoot productivity by 17%; while using paranet 75% could reduced radiation transmission by 36% and reduced temperature by 0.6ᵒC, and reduced shoot productivity by 59%, respectively.

Judul: Pengaruh berbagai teraf naungan pohon kelapa dan nitrogen terhadap pertumbuhan dan produksi rumput paricum maximum C. V. Riversdale
Abstrak: Penelitian ini bertujuan untuk mengetahui pengaruh beberapa taraf naungan pohon kelapa dan nitrogen terhadap produksi dan pertumbuhan serta ketenggangan rumput Panicum maximum cv .Riversdale. Percobaan dilaksanakan di Kebun Percobaan Balai Penelitian Kelapa Manado Kima Atas. Percobaan disusun dalam Rancangan Petak Terbagi. Berdasarkan rancangan ini taraf naungan 0,20 dan 73 % PAR (Ph otosyntetically Active Radiation) diletakkan pada petak utama dengan taraf nitrogen 0,100 dan 200 kg ha-1 pada anak petak. Seluruh perlakuan diulang tiga kali. Hasil analisis keragaman menunjukkan perbedaan yang nyata setelah diuji lanjut dengan uji BNJ pada taraf 5 %. Hasil percobaan menunjukkan, bahwa bobot kering tanaman tertinggi mencapai 409,40 gr/m 2 pada pemupukkan nitrogen 200 kg ha-1 dan naungan O % atau sinaran penuh. Bobot kering akar tertinggi yang dicapai 23,91 gr/3 rumpun akar pada O % dan nitrogen 200 kg ha-1. Interaksi taraf naungan dan nitrogen ditemukan baik pada bobot kering tanaman maupun pada bobot kering akar. Kandungan protein kasar tertinggi dicapai pada taraf naungan 73 % maupun pada taraf nitrogen tertinggi (200 kg ha-1) masing-masing sebesar 14,93 dan 14,35 % dari bahan kering. Pengaruh interaksi antara perlakuan terhadap kandungan protein kasar tanaman tidak nyata. Proporsi bobot kering daun dan batang tertinggi kg ha-1 dicapai pada taraf naungan O % dan nitrogen 200 rnasing-masing sebesar 239,30 dan 170,00 gr m-2. Interaksi taraf naungan dan nitrogen ditemukan baik pada bobot kering daun maupun pada bobot kering batang. ...

Judul: Grup dan Homomorfisma Grup pada Rubik Revenge
Abstrak: Rubik cube is a kind of puzzle game. A player must arrange rubik sides, which have been disordered, back to the position where every side has the same colour. This paper does not focus on the settlement solution, but instead on proving the existence of a group homomorphism between rubik movement group and S96 symmetric permutation group in rubik revenge. Firstly, it has been proved that rubik movement set is a group. Then, it also has been proved that the M set, which contains numeric labels of 1 until 96 in cubinos sides, is S96 symmetric permutation group.
