Penelitian ini bertujuna untuk menentukan ada tidaknya interaksi dari faktor pengolahan tanah dan faktor varietas jagung yang berpengaruh terhadap pertumbuhan dan hasil maksimal, untuk mengetahui varietas jagung yang berpotensi hasil tinggi dengan sistem pengolahan tanah yang efektif dan efisien pada lahan kering. Menentukan sistem pengolahan tanah yang efektif dan berpotensi untuk mendapatkan hasil yang maksimal. Penelitian dilaksanakan di lahan perkebunan Desa Molompar Kecamatan Tombatu Timur Kabupaten Minahasa Tenggara dari bulan November 2016 sampai Februari 2017. Penelitian ini menggunakan Rancangan Petak Terbagi (Split-Plot Design) dengan dua faktor. Faktor pertama adalah sistem pengolahan tanah yang terdiri dari tiga macam perlakuan dan faktor kedua yaitu varietas jagung yang terdiri atas 4 macam varietas. Sistem pengolahan tanah yang diterapkan adalah : P1: Petak dikelola dengan system Tanpa Olah Tanah, P2: Petak dikelola dengan system Olah Tanah Minimum, P3: Petak dikelola dengan system Olah Tanah Sempurna.Varietas jagung yang digunakan V1: benih jagung varietas TS 333,V2 : benih jagung varietas Pioneer,V3 : benih jagung varietas Bisi 18, dan V4 : benih jagung varietas DK 88. Data yang diperoleh akan dianalisis dengan menggunakan analisis varians jika berbeda nyata akan dilanjutkan dengan Uji Beda Nyata Terkecil (BNT). Variabel yang diamati terdiri dari tinggi tanaman (cm), yaitu dilakukan mulai dari pangkal batang sampai ujung daun tertinggi yang diluruskan secara vertikal ke atas pada saat tanaman berumur 14 HST kemudian dilanjutkan pada 40 HST. Komponen hasil jagung hibrida yaitu jumlah baris biji/tongkol, dilakukan dengan cara menghitung jumlah baris pada tongkol dan jumlah biji/baris dihitung jumlah biji jagung setiap baris. Hasil penelitian menunjukkan bahwa tidak ada interaksi antara system pengolahan tanahn dan jenis varietas pada pertumbuhan dan hasil tanaman jagung. Pada perlakuan pengolahan tanah, Sistem Tanpa Olah Tanah mengahsilkan tanaman yang lebih tinggi dari pada system olah tanah lainnya. Pada perlakuan varietas, varietas Bisi menghasilkan jumlah biji perbaris terbanyak dari pada varietas lainnya.

ABSTRACT The corelation cell specialization with IAA (indole acetic acid) contentÂ of Catharanthus roseus cell culture by the addition of tryptophan has been done. This research is part of a strategy to increased the catharanthine content. One strategy used is the addition of tryptophan as a precursor treatment. IAA was other compound of the effect of the addition of tryptophan. Research was conducted in the laboratory using MS medium with tryptophan 50-250 mg/L. The cell morphology observations made by Halogen Nikon microscope and documented with a digital camera Nikon DXM 1200F. The results showed that cell morphology is essentially the same for each treatment. The differences seen is the presence of more the long cells in the treatment of tryptophan. The longest ratio is the treatment of 150 mg/L tryptophan at day 14 of culture. Changes in cell morphology relationship more long (run specialization) has something to do with the IAA content after treatment tryptophan. The highest IAA content equal 214,79Â±0,90 Â Âµg/g dw Â was occurred at day 14th after being treated tryptophan 150 mg/L with 75% long cells or cells specialization. The relationship between the content of IAA specialized cells showed a positive correlation of 0.80 or 80% of each other. Key words: Cell specialization, IAA content, catharanthine, tryptophan, Catharanthus roseus ABSTRAK Â Hubungan antara spesialisasi sel dengan kandungan IAA (asam indol asetat) kultur sel Catharanthus roseus dengan perlakuan triptofan telah dilakukan. Penelitian ini merupakan bagian dari strategi peningkatan kandungan katarantin. Salah satu strategi yang digunakan adalah penambahan perlakuan triptofan sebagai prekursor. IAA merupakan hasil sampingan sebagai pengaruh penambahan triptofan. Penelitian ini dilakukan di laboratorium dengan menggunakan media MS dengan triptofan 50-250 mg/L. Pengamatan spesialisasi sel dilakukan dengan mikroskop Nikon HalogenÂ dan didokumentasikan dengan kamera digital Nikon DXM 1200F. Bentuk sel pada dasarnya sama untuk setiap perlakuan. Perbedaan yang terlihat nyata adalah adanya sel-sel panjang lebih banyak pada perlakukan triptofan. Perlakuan yang paling panjang rationya adalah pada perlakuan 150 mg/L triptofan pada hari ke-14 kultur. Hubungan perubahan bentuk sel yang lebih banyak panjang (mengalami spesialisasi) ada hubungannya dengan kandungan IAA dan katarantin yang meningkat selelah perlakuan triptofan. Kandungan IAA paling tinggi yaitu sebesar 214,79Â±0,90 Â Âµg/g bk Â terjadi pada hari ke 14 selelah diberi perlakuan triptofan 150 mg/L dengan persentasi sel panjang atau sel mengalami spesialisasi 75%. Hubungan antara spesialisasi sel dengan kandungan IAA menunjukkan hubungan yang positif sebesar 0,80 atau 80% saling menunjang.

AbstractÂ Â Rante Lembang, V.W., W. Tilaar, dan T.M. Frans, 2015. The Ecological Potential, Dispersion Patterns and Utilization Patterns of Natural Fiber in The Limited Production Forest (LPF) of Sinonsayang Mount, North SulawesiÂ Â In Province of North Sulawesi, natural fiber plants (bast plant) were found scattered either in primary forests area or secondary forests area, including in the limited production forest area (LPF) ofÂ Sinonsayang Mount. The information regards to the ecological potential, dispersion pattern, and the pattern of utilization in the region is not yet known with certainty, it is therefore need to be observed. The aim of the research was to describe the ecological potential, dispersion patterns, and the utilization patterns of natural fibers within the limited production forest (LPF) of Sinonsayang Mount, North Sulawesi. This was conducted for 2 (two) months in the limited production forest (LPF) of Sinonsayang Mount, particularly, in the area which have been used by the community as a dry land farming and the shrubs overgrown area (Â± 500 acres).Â The inventory method was used in this research, in which the plots were placed randomized using random sampling pattern (simple random sampling). The results shows, there were five (5) types of natural fibers found in the inventory field, namely: bamboo, pandanus, cotton, agave, and rosella. The bamboo population per hectare was higher than other types of natural fibers, amounting to 19 â‰¤ individual / ha â‰¤ 21, while the rosella type was found as the smallest population, about 0.08 â‰¤ individual / ha â‰¤ 0.09.. The frequency value, and the percentage value of each type of bamboo natural fiber was 0.73, and 95.66%, respectively, while the frequency value and the percentage value of each type of rosella natural fiber was the lowest, that is 0.02 and 0.04%, respectively. The dispersion pattern bamboo natural fiber types were randomly spreaded in the region, while the other types of natural fibers (pandanus, cotton, agave, and rosella) were spreaded out in groups. As for of the 5 (five) natural fibers types that found, there is only 3 types of natural fiber used by the public, viz: bamboo, pandanus, and cotton. The natural 3 Â fiber of bamboo was the most widely used by the community, both for personal consumption and for sale to the village market, and the market district.Â There were 11 forms of utilization of natural bamboo fiber by the communities surrounding the forest area for the purposes, consist of: making walls of house / cottage garden, fence, stairs, livestock pen, nesting of laying hen, ethanol refining installation of aren, to build furnace wall, medium to cook fish / pie, rice winnower, groceries bamboo shoots (young shoots), and for lalandangan. Meanwhile, the utilization of natural fibers of pandan and cotton were still limited for their own consumption as a raw material for making mats, pillows, and the fuse of the bottle lights.
