This research aims to produce a shorter cloves and generate more interest and qualified by the presence of paclobutrazol treatment. The results showed that the high accretion paclobutrazol can produce the content of chlorophyll a (0,032 mg g -1 ) and chlorophyll b (0,004 mg g -1 ), dry weight of 1000 grains (207 g) and dry weight / plant (6.038 kg) was 8 years old clove higher than the control. Recommended further research to determine the maximum effect of paclobutrazol application on plants. Paclobutrazol at a dose of 2.5 g / tree height increment can deliver maximum results of cloves. ABSTRAKPenelitian ini bertujuan untuk menghasilkan tanaman cengkeh yang lebih pendek dan menghasilkan bunga yang lebih banyak serta berkualitas oleh karena adanya perlakuan paclobutrazol. Hasil penelitian menunjukkan bahwa paclobutrazol dapat menghasilkan kandungan klorofil a (0,032 mg g -1 ), dan klorofil b (0,004 mg g -1 ), bobot kering 1.000 butir (207 g) dan bobot kering/pohon (6,038 kg) cengkeh berusia 8 tahun lebih tinggi dibanding kontrol. Disarankan penelitian lanjutan untuk mengetahui batas maksimum pengaruh aplikasi paclobutrazol terhadap tanaman. Paclobutrazol dengan dosis 2,5 g/pohon dapat memberikan hasil maksimal pada tanaman cengkeh.

The research aims to assess the response to the growth and production of onion against of liquid organic fertilizer from cow biourie in some concentrations and to get the best concentration for the growth and production of red onion. The research was conducted atfield experimental in Pandu, North Minahasa regency from May to July 2014. The experiment was designed using a randomized block design. The treatment was concentration of cow biourine namely 0% (B 1 ) 10%, (B 2 ) 20%, (B 3 ) 30%, (B 4 ) 40% and (B 5 ) 50%. Each treatment was replicated three times. Characters observed were plant height, number of leaves, tuber diameter, number of tuber, fresh weight of tuber with leaves and dry weight of tuber. Data was analyzed using analysis of variance. The result showed that the biourine concentration had significant effect on plant height, number of leaves, tuber diameter, number of tuber, fresh weight of tuber with leaves and dry weight of tuber. Treatment of B1, B2, B3 and B4 concentration were not significant difference at plant height. However, those four treatments were significantly different compared to B0 and B5. The fives treatment differed with the control on characters of number of leaves, number of tuber andfresh weight of tuber with leaves. On character of tuber dry weight, B2 treatment was significant difference compared to control whereas the other treatments were not significantly differed. On character of tuber diameter, three treatments were significant difference compared to the control namely B2, B4 and B5.

Hasil penelitian menunjukkan bahwa konsentrasi biourine memiliki pengaruh yang signifikan terhadap tinggi tanaman, jumlah daun, diameter umbi, jumlah umbi, berat umbi segardengan daun dan berat umbi kering dengan daun. Perlakuan konsetrasi B1, B2, B3 dan B4 tidak ada perbedaan yang signifikan pada tinggi tanaman. Namun, empat perlakuan berbeda secara signifikan dibandingkan dengan B0 dan B5. Lima perlakuan berbeda nyata dengan kontrol pada karakter jumlah daun, jumlah umbi dan berat segar umbi dengan daun. Pada karakter berat umbi kering dengan daun, perlakuan B2 berbeda secara signifikan dibandingkan dengan kontrol sedangkan perlakuan lainnya tidak berbeda secara signifikan. Pada karakter diameter umbi, tiga perlakuanyaitu B2, B4 dan B5memberikan pengaruh yang signifikan dibanding ...
Mangrove is one of plants that can grow well on the coast which are affected by tides.Bone Baru village is located in North Banggai District, Banggai Laut Regency, Central Sulawesi Province which has area that about 840 ha and has mangrove area reaching 16.56 ha. This research was conducted from February to April 2020. The purpose of this research are to identify the types of mangroves and analyzing the structure of the mangrove community which include density, relative density, frequency, relative frequency, coverarge, relative coverage, importance value index, and diversity index. The data were analyzed using Microsoft Excel. Based on the results this study obtained 4 types of mangroves consisting of Bruguiera gymnorrhiza, B. cylindrica, Rhizophora mucronata, and Lumnitzera littorea. The highest relative density was 0.13 ind / m2 and the relative density was 91.83% the highest frequency type and the frequency relative value were 5 ind / m2 and 52.63%respectively. The highest mangrove cover was 3.79 m2 with relative cover of 52.21%. The highest important value index was 227.72% . The highest diversity index was found at station 2 with an average value (H ') of 0.69.Keywords: mangrove, community structure, habitat, BanggaiABSTRAKMangrove merupakan kelompok tumbuhan yang dapat tumbuh dengan baik di pesisir pantai yang dipengaruhi oleh pasang surut air laut.

This study aimed to examine the growth and production of potato crop varieties and varieties Granola Supejhon on two altitude, which is 750 m above sea level and 1200 m above sea level, studies using randomized block design with two factors. The first factor is the Granola variety and Supejhon. The second factor is the altitude, which is 750 m above sea level and 1200 m asl. The results of this study indicate that the rate Crop Growth Rate (LTT) and the Tuber Growth Rate (LTU) of Supejhon Granola varieties have a much higher altitude 1200 m asl (Modoinding) compared with altitude 750 m asl (Langowan). The altitude effect on the number of tubers / plant and production / plot, otherwise varieties had no effect on the number of tubers / plant, weight of tubers / plot and production / plot, and there is no interaction between variety and altitude. At altitude 750 m asl, both varieties yield an average production of tubers / plot of 1343.20 g (1.34 kg), whereas the altitude of 1200 m asl generate 7462.18 g (7.46 kg). Based on the average, the weight of tubers / plant and production / plots at very low reached by the two varieties of Granola and Supejhon well, so that the two varieties are not recommended to be cultivated at altitude 750 m above sea level. Further research is needed to examine other potato varieties that can be cultivated in areas with altitude of 750 m asl. ABSTRAKPenelitian ini bertujuan untuk mengkaji pertumbuhan dan produksi tanaman kentang varietas Granola dan varietas Supejhon pada dua ketinggian tempat, yaitu 750 m dpl dan 1200 m dpl, penelitian menggunakan Rancangan Acak Kelompok dengan dua faktor. Faktor pertama adalah varietas Granola dan Supejhon. Faktor kedua adalah ketinggian tempat, yaitu 750 m dpl dan 1200 m dpl. Hasil penelitian ini menunjukkan bahwa Laju Tumbuh Tanaman (LTT) rata-rata dan Laju Tumbuh Umbi (LTU) rata-rata varietas Granola dan Supejhon memiliki nilai yang jauh lebih tinggi pada ketinggian tempat 1200 m dpl (Modoinding) dibandingkan dengan ketinggian tempat 750 m dpl (Langowan). Ketinggian tempat berpengaruh terhadap jumlah umbi/tanaman dan produksi/petak, sebaliknya varietas tidak berpengaruh terhadap jumlah umbi/tanaman, bobot umbi/petak dan produksi/petak, serta tidak terdapat interaksi antara varietas dan ketinggian tempat. Pada ketinggian tempat 750 m dpl, kedua varietas menghasilkan rata-rata produksi umbi/petak sebesar 1343,20 g (1,34 kg), sedangkan pada ketinggian tempat 1200 m dpl menghasilkan 7462,18 g (7,46 kg). Berdasarkan nilai rata-rata, bobot umbi/tanaman dan produksi/petak yang sangat rendah dicapai oleh kedua varietas baik Granola maupun Supejhon, sehingga kedua varietas tersebut tidak dianjurkan untuk dibudidayakan pada ketinggian 750 m dpl. Perlu dilakukan penelitian lanjutan untuk menguji varietas kentang lainya yang dapat dibudidayakan pada daerah dengan ketinggian tempat 750 m dpl.
