ABSTRAKKondisi perairan laut yang fluktuatif dan cenderung ekstrim menyebabkan rumput laut mudah terserang penyakit ice-ice. Munculnya bercak putih pada thallus rumput laut Eucheuma cottonii yang terinfeksi penyakit ice-ice diduga disebabkan oleh bakteri patogen yaitu Pseudomonas spp. Tujuan yang ingin dicapai dalam pelaksanaan penelitian ini adalah untuk mengetahui pengaruh perbedaan salinitas terhadap viabilitas bakteri Pseudomonas spp dan untuk mengetahui pada salinitas berapakah bakteri Pseudomonas spp tidak dapat tumbuh. Bakteri diidentifikasi melalui uji biokimia, dan viabilitas diamati dengan menanam bakteri pada media TSA plate dengan salinitas 30, 32, dan 34 ppt dengan 3 kali pengulangan, dan untuk uji konfirmasi bakteri di tanam pada media TSA miring dengan kadar salinitas 0, 20, 40, 60, 80, dan 100 ppt. Hasil yang diperoleh menunjukan bakteri tumbuh dengan normal pada hampir semua media uji kecuali pada media 100 ppt, hal ini menunjukan bahwa bakteri Pseudomonas spp merupakan bakteri yang bersifat halofilik atau dapat tumbuh baik pada kadar salinitas yang tinggi.

The Influence of Salinity Difference to Viability of Pseudomonas spp. BacteriaABSTRACTThe conditions of marine waters that fluctuate and tend to extremes can cause seaweed susceptible to ice-ice disease. The appearance of white patches on infected Eucheuma cottonii seaweed thallus is estimated as ice-ice disease which is caused by pathogenic bacteria of Pseudomonas spp The objectives of this research is to determine the effect of salinity difference to viability of bacteria Pseudomonas spp and to know on what salinity is the bacterium Pseudomonas spp that can’t grow. Bacteria were identified by biochemical tests. Viability was observed by planting bacteria on TSA plate medium with salinity 30 ppt, 32 ppt, and 34 ppt with 3 repetitions, and for bacterial confirmation test in planting on TSA tilting with salinity 0 ppt, 20 ppt, 40 ppt, 60 ppt, 80 ppt, And 100 ppt. The results showed that bacteria grew normally in almost all test media except in 100 ppt media, this showed that Pseudomonas spp bacteria were halophilic bacteria or could grow well at high salinity levels.Keywords: Eucheuma cottonii, ice-ice, Pseudomonosa spp, Viability.

Pineapple (Ananas comosus L.) is one of the most potential fruit crop cultivating in Indonesia. However, it is difficult to meet the demand for planting materials using the conventional propagation techniques due to production inefficiency. This research aim to know the influence solid medium of Murashige and Skoog (MS) composed of Indol-3-Butiric Acid and Thidiazuron, upon pineapple Var Smooth Cayenne shoot multiplication response. Shoot multiplication using a factorial complete random design. The first is a 3-level IBA concentration (0.3 ppm, 0.6 ppm, 0.9 ppm), a 3-level TDZ concentration (0.2 ppm, 0.4 ppm, 0.6 ppm). The finding shows that MS richly composed IBA and TDZ with low concentration gives 100% shoot the fastest periodic appearance (two weeks after incubation). Varians analysis finding shows that there is no interaction between IBA and TDZ.Low IBA concentration gives the higest quantity of shoot 9.32 (5.60 data transformation) at 5 week after incubation, at the end of the analysis tends to give the higest shoot 11.17 (6.18 data transformation) even though it is statistically not slighty difference. The highest TDZ concentration (0,6 ppm) give a few number of roots 0.89 (2,65 data transformation) and the lowes shoots leaf 3.84 (4.04 data transformation). The higher the TDZ is, the more nodal may appear.

Watermelon (Citrullus vulgaris, Schard) is a seasonal fruit playing an important role in economic improvement of a household and a nation as well. An effort to cultivate watermelon greatly supports the improvement offarmers' standard of living. Its Physical appearance and itsflesh color are greatly attractive. It has various stripped shape (elips, round and oval) and has highly enough nutrition.The aims of this stud y were to discover diploid watermelon varieties used as good polinator and has more strengths than both of its parents. This stud y applied Randomized Block Design with two replications treating nine (9) seeded watermelon and two (2) triploid verities. Thevarieties used as male parents were diploid variety (Pl), Diana Bangkok Dragon (P2), China Dragon (P3), Black sweet (P4), Golden Fresh (PS), Hitam manis (p6 ), Grand Master (pl), TM Tiger (PB), and Red Super Dragon (P9). Pretty Orchid (V1) and Champion (V2) were used asfemale parents.The results of this stud y showed that different polinators had different influences in determining the agronomic possibility of bearing fruit, sugar content,fruit length,fruit diameter except harvesting age and fruit weight. The best agronomic properties resulted from well crossing were shown byfruit diameter and sugar content. Withinvariety-crossing of all polinator with thefemale Pretty Orchid (V1) showed good results except the polinator Hitam Manis (p6 ). The greatest fruit diameter resulted from polinator Grand Master (Pl) was 22.59 cm dan the smallest resulted from Hitam Manis polinator (P6) was 20.20 cm

The main disease in maize is downy mildew caused by the fungus Peronosclerospora spp.. This pathogen can cause yield losses of up to 100%. Therefore, efforts to control this disease are continuously carried out, including technical culture, assembly of resistant plants, and use of synthetic fungicides. At the farm level, the use of metalaxyl, synthetic fungicides is the most common practice. On the other hand, it has been reported that some Peronosclerospora groups are starting to become resistant to metalaxyl. These problems lead to the need for alternative controls, for example with biological agents. Biological agents from bacterial groups have been developed to control plant disease, but for downy mildew is still limited. The purpose of this study is to screen and test Bacillus spp. ability to suppress downy mildew and promote the growth of maize. The assay was carried out on seeds by invitro to investigate growth-promoting reactions and also testing under controlled conditions in greenhouses to investigate the suppression ability of downy mildew disease development. The results showed B. polymyxa strain BP18, Bacillus subtilis strain BS41, Bacillus sp. strain BT1, and Bacillus sp. strains can stimulate the growth of corn seedlings and suppress downy mildew. The best isolate in suppressing downy mildew was Bacillus sp. strain BT1 with the smallest AUDPC value (3.94) and the highest protection index (82.71%). It is hoped that these results will find potential isolates and have the potential to be developed into biopesticides and biofertilizers.

Tanaman Kacang Bambara dikenal sebagai salah satu tanaman yang tahan terhadap kekeringan. Tanaman ini berasal dari Afrika yang kemudian dikembangkan di Indonesia. Penelitian ini bertujuan untuk mengetahui ketahanan beberapa galur kacang bambara terhadap kekeringan serta kebutuhan air minimum yang dibutuhkan tanaman untuk tetap tumbuh dan berproduksi dengan baik. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) Faktorial dengan 3 kali ulangan. Terdiri atas 4 galur (G1, G2, G3, G4) dan 4 taraf penyiraman (P1, P2, P3, P4) sehingga terdapat 16 kombinasi perlakuan. Perlakuan galur memberikan pengaruh terhadap parameter hasil (umur berbunga, jumlah polong, panjang akar, jumlah biji dan berat biji), sedangkan penyiraman mempengaruhi semua parameter pengamatan. Taraf penyiraman 100% kapasitas lapang (P1) memberikan pengaruh terbaik pada setiap parameter pengamatan, sedangkan interaksi terbaik ditunjukkan pada G4P4 pada setiap parameter pengamatan. Kebutuhan air minimum tanaman kacang bambara yaitu pada taraf penyiraman 75% Kapasitas Lapang (P2).

Genetic variation is a prerequisite for many breeding program that one of which can be generated through somaclon variation. The objective of this research was to investigate effective media to induce embryo callii and to do in vitro callii regeneration for maize, and in vitro selection was conducted by growing embryogenic callii on mediun containing polyethylene glycol (PEG). Plant material used in this study was 5 madura cultivars i.e elos, tambin, guluk-guluk, talango and manding. The results showed that (1) increasing addition 2,4-D on MS medium was significantly affected callii weight, however supplying 8 ppm 2,4-D was best for callii diameter, (2) The best medium to induce embryogenic callii formation was MS + 2 ppm 2,4-D + 3% manitol, (3) Increasing addition PEG on MS medium can return the mays ES growth, and (4) A tambin and guluk-guluk cultivars was tolerance cultivars whereas manding cultivar was drought sensitive cultivar.
