Abstract

Local apple production, especially Anna's apples, continues to decline. One of the Causes of the decline in local apple production is due to the disproportionate use of chemicals, which causes ethylene production in plants to increase. The purpose of this study was to examine the effect of salicylic acid on reducing levels of ethylene concentrations in Anna apple plants. This study used a completely randomized design (CRD) with a single factor, namely the treatment of various salicylic acid concentrations (25 ppm, 50 ppm, 100 ppm, 200 ppm). The results showed that salicylic acid was able to reduce the value of ethylene concentration in plants. Provision of salicylic acid concentrations starting at 25 ppm was able to inhibit ethylene biosynthesis by more than 90%. The best results were shown in samples treated with 200 ppm salicylic acid concentration. By using salicylic acid alternatives, farmers are able to save around Rp3,040,400 in costs in one harvest period. The percentage of costs for salicylic acid in one harvest period is 3.39% of the total production costs, while the cost of the import promoter is 7.92% of the total production costs

Abstract

Gunung Batok merupakan satu diantara gunung-gunung di Taman Nasional Bromo Tengger Semeru yang merupakan habitat edelweis (Anaphalis Javanica). Keberadaan edelweis di gunung batok pada beberapa tahun terakhir mulai terancam kelestariannya karena kebakaran dan perambahan oleh warga sekitar dan wisatawan. Berdasarkan hal tersebut maka perlu dilakukan penelitian tentang distribusi dan kepadatan edelweis (A. javanica) di Gunung Batok Taman Nasional Bromo Tengger Semeru dengan tujuan untuk mengetahui pola penyebaran dan kerapatan edelweis (A. javanica) di Gunung Batok Taman Nasional Bromo Tengger Semeru.Penelitian ini bertujuan untuk mengetahui kerapatan edelweis (A.javanica) dan distribusinya serta faktor lingkungan apa yang paling mempengaruhi terhadap kelimpahan edelweis (A. javanica). Penelitian ini dilaksanakan di Gunung Batok Taman Nasional Bromo Tengger semeru pada bulan April sampai dengan September 2010. Penelitian bersifat deskriptif kuantitatif. Pengambilan sampel dilakukan dengan membagi Gunung Batok menjadi 4 stasiun berdasarkan arah mata angin. Setiap stasiun dipasang transek dengan panjang 50 m sebanyak 10 transek. Faktor lingkungan yang diamati meliputi kelembaban, suhu, dan kecepatan angin. Data kerapatan dianalisis dengan rumus jumlah edelweis/luasarea, pola distribusi edelweis dianalisis dengan menggunakan Indeks Morisita dengan uji Chi-square dan hubungan factor lingkungan dan kelimpahan edelweis (A. javanica) dianalisis dengan regresi ganda. Setiap edelweis (A. javanica) yang ditemui ditandai titik koordinatnya dengan GPS, kemudian untuk mengetahui posisi edelweis di Gunung BatokTaman Nasional Bromo tengger Semeru data diolah menggunakan google earth. Hasil penelitian menemukan 115, edelweis/ha. Berdasarkan analisis Indeks Morisita menunjukkan bahwa pola penyebaran edelweis (A. javanica) cenderung mengelompok dan setelah di uji lanjut dengan uji chi-squere diketahui bahwa distribusinya seragam. Semua variabel independen (suhu, kelembaban dan kecepatan angin) tidak mempunyai korelasi yang erat terhadap variabel bebas (kepadatan Edelweis (A. javanica)) di Gunung Batok Taman Nasional Bromo Tengger Semeru

Abstract

Pemuliaan   tanaman   merupakan   suatu   kegiatan   yang   dilakukan   untuk memperbaiki karakter tanaman secara baka. Pemuliaan secara konvensional biasanya dilakukan melalui seleksi terhadap karakter-karakter yang menjadi target  atas dasar ciri- ciri fenotip/morfologi, namun penggunaan penanda morfologi ini kurang akurat dan tidak stabil karena karakter yang tampak bukan semata-mata menggambarkan informasi genetic tanaman tetapi sudah dipengaruhi oleh lingkungan. Seleksi yang akurat terhadap suatu karakter yang diinginkan dari tanaman       adalah  denga    berdasarkan  pada  gen  yang mengendalikan karakter tersebut. Untuk  itu maka identifikasi genetic dengan pendekatan molekuler sangat dibutuhkan dalam kegiatan pemuliaan ini agar memperoleh hasil yang tepat dalam waktu yang singkat.

Abstract

Orthodontic tooth movement is obtained through alveolar bone remodeling. Alveolar bone remodeling includes resorption process that played by osteoclasts and bone formed process that played by osteoblasts. Diabetes affects on orthodontic tooth movement. The magnitude of orthodontic force that applied in the early stages of diabetic conditions, would be a consideration of the alveolar bone remodeling process. The purpose of this study was to determine osteoblast and osteoclast profile in early stage of rat diabetic models with different orthodontic force application. 24 Wistar rats were divided into three groups of controls andthree groups of early stage of diabetic treatment with different orthodontic force application (10, 20, and 30 gramforce/grf). The results showed an increased of osteoclast numbers in early stage of diabetes and will be increased along with the increased of orthodontic force. The results also showed a decreased of osteoblast number in early stage of diabetes, but it would be increased along with the increased of orthodontic force.

Abstract

Drought is one of the most severe limitations on the productivity of soybean. There are many genes and proteins involved in drought stress tolerance.  Identification of proteins which could be used as the base for the development of molecular study is very important to understand drought tolerance thoroughly. The objective of the research was to investigate protein expression of soybean to drought stress. Changes in protein expression were analyzed using SDS PAGE and two dimensional gel electrophoresis. Image analysis of 2D protein was performed by using the PDQuest 8.0 software program (Bio-Rad). Tolerant variety, Dering-1, was subjected to drought stress using limitation of watering, while Detam-1, a sensitive variety, was used as comparator.  The result showed that protein concentration have decreased in drought condition from 3,22 mg/ml to 0,77 mg/ml. The new protein band with the 24,95 kDa have been found in drought condition. This protein is osmotin like protein with the accession number NP915414 which may play a role in the mechanism of drought resistance. The identification of the protein based on sequence amino acid literature review

Abstract

Kondisi stres kekeringan secara in vitro dapat disimulasi dengan menurunkan potensial air media, yaitu dengan penambahan PEG (polietilena glikol). Penapisan secara in vitro dilakukan dengan memanfaatkan komponen penyeleksi yang dapat mensimulasikan cekaman lingkungan. Pada penapisan in vitro, penambahan komponen seleksi harus dipilih, sehingga pada konsentrasi yang tepat dapat mengelompokkan verietas kedelai yang peka, moderat dan toleran. Salah satu respon tanaman terhadap cekaman kekeringan yaitu terjadi perkecambahan yang abnormal. Tujuan penelitian ini ialah untuk mengetahui respon perkecambahan varietas kedelai yang ditanam pada media in vitro dengan penambahan PEG 6000 dan untuk mengetahui konsentrasi PEG yang mampu menyeleksi varietas kedelai peka dan toleran kekeringan pada media padat dan media cair.Penelitian ini terdiri dari 2 tahap yang pertama pengujian pada media padat, menggunakan  Rancangan Acak Lengkap (RAL) 2 faktor.  Faktor pertama adalah konsentrasi PEG 6000 yang terdiri dari 4 taraf perlakuan (0 gr/l; 20 gr/l; 40 gr/l dan 60 r/l), dan faktor kedua adalah varietas kedelai (Wilis, Tanggamus, Grobogan, Argomulyo, Kaba dan Panderman). Penelitian ini menggunakan 24 kombinasi perlakuan dengan 3 ulangan.  Penelitian kedua pengujian pada media cair, menggunakan  Rancangan Acak Lengkap (RAL) 2 faktor.  Faktor pertama adalah varietas kedelai yang terdiri dari 3 taraf yaitu: Wilis, Tanggamus dan Grobogan. Faktor kedua adalah konsentrasi PEG 6000 yang terdiri dari 4 taraf perlakuan yaitu: 0%, 5%, 10% dan 15%, yang masing-masing setara dengan potensial air 0; -0,13; -0,19; -0,41 MPa. Pada penelitian media padat, berdasarkan hasil indeks sensivitas kekeringan, varietas Grobogan, Argomulyo dan Kaba menunjukkan respon peka kekeringan, sedangkan varietas Wilis dan Argomulyo menunjukkan respon toleran kekeringan dan varietas Tanggamus menunjukkan respon medium toleran. Konsentrasi PEG 60 gr/l  mampu mensimulasi kekeringan pada media padat.  Pada media cair, berdasarkan indeks sensivitas menunjukkan varietas Tanggamus dan Wilis bersifat medium toleran dan Grobogan peka terhadap kekeringan.  Konsentrasi PEG 5% pada media MS cair in vitro mampu mensimulasikan cekaman kekeringan.Kata kunci :  Pengujian in vitro, varietas kedelai, media padat, media cair
