Aklimatisasi merupakan tahap yang kritis bagi plantlet. Pada lingkungan yang baru plantlet dapat mengalami cekaman lingkungan. Kondisi lingkungan seperti media yang tidak mendukung pada tahap aklimatisasi dapat menyebabkan kematian plantlet. Penelitian ini bertujuan: 1) Mendapatkan kombinasi media yang paling baik bagi keberhasilan aklimatisasi plantlet anggrek Phalaenopsis; 2)Mengetahui apakah terdapat interaksi antara media bagian bawah dengan atas pot; 3) Mendapatkan kombinasi media yang paling baik bagi pertumbuhan bibit anggrek anggrek Phalaenopsis pada tahap pembesaran, dan 4) Melihat apakah media sabut kelapa dapat digunakan untuk aklimatisasi dan pembesaran anggrek Phalaenopsis. Penelitian dilaksanakan di rumah jaring Politeknik Negeri Lampung dari bulan Maret hingga Agustus 2018. Plantlet diaklimatisasikan 4 minggu. Percobaan faktorial dilaksanakan dalam rancangan acak kelompok. Faktor A : macam media bagian bawah (bata/arang). Faktor B : macam media bagian atas (moss sphagnum/pakis/sabut kelapa). Enam kombinasi perlakuan dicobakan (masing-masing dengan 10 ulangan), yaitu:  P1 (bata+moss); P2 (bata+pakis); P3 (bata+sabut kelapa); P4 (arang+moss); P5 (arang+pakis); dan P6 (arang+sabut kelapa). Peubah yang diamati: 1) persen keberhasilan plantlet menjadi bibit, 2) tinggi bibit, 3) panjang daun, 4) lebar daun, dan 5) jumlah daun.  Data yang diperoleh dilakukan analisis ragam dan dilanjutkan dengan uji BNJ 5%. Hasil penelitian menunjukkan: 1) Media moss atau pakis dikombinasikan dengan bata maupun arang memberikan persen keberhasilan aklimatisasi plantlet anggrek Phalaenopsis yang paling baik (100%); 2) Tidak terdapat interaksi antara media bagian atas dengan bagian bawah; 3) Kombinasi media yang paling baik bagi pertumbuhan bibit anggrek Phalaenopsis pada tahap pembesaran adalah moss baik dikombinasikan dengan bata ataupun arang, kemudian diikuti oleh pakis (dikombinasikan dengan bata ataupun arang); dan 4) Media sabut kelapa dapat digunakan untuk aklimatisasi dan pembesaran bibit anggrek Phalaenopsis bila dilakukan penyiraman yang lebih intensif.
Banana is one of the most important global agriculture commodities. Asia accounts for the production of bananas amounted to 56.4% of total banana in the world and Indonesia is one of the banana-producing countries in Asia. The demand for bananas increased need is anticipated with good cultivation techniques to meet domestic and international market demand. Plant regeneration in vitro tissue culture techniques or can be used to produce propagules true-to-type in large quantities in a relatively short period and free from disease. This research aims to study the influence of various concentrations of BA (0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, and 4.0 mg/l) against the growth and reproduction of Cavendish banana propagules in vitro. Time appears buds, propagules length and the number of propagules per explant, and the number of primary roots of plants per explant observed after eight weeks of culture. The experiment results show that after explant grown for eight weeks on the media's treatment shows the different response. The increased concentration of BA can increase the number of shoots. The increased concentration of BA from 0.5 mg/l be 1-3 mg/l increased the number of propagules, but the number of propagules will decrease in the concentration of BA more 3.5 or 4 mg/l. In addition to BA concentration 0.5, 1 and 1.5 mg/l MS media into producing shoot buds appear faster time high, highest propagules and root amount more on banana propagules Cavendish, but the number of shoots is fewer. The best of BA concentrations to induce propagules plant bananas Cavendish is 3.0 mg/l.
Strategy of tourism destination branding is an important factor in the the process of tourism development of a region. As well as it happens in Aceh, which is the only province in Indonesia applying the islamic sharia. The purpose of this study is to determine and analyze the strategy of destination branding conducted by Department of Culture and Tourism in Aceh. The strategy is started from the vision and stakeholder management, target consumer and portfolio matching, positioning and differentiation strategies using brand components, communication strategies, feedback and response management strategies. The theory used to analyze this strategy is the theoretical principles of tourism destination branding. This study is qualitative descriptive with the case study method. Data collecting method is conducted through in-depth interviews with 8 informants coming from branding team, observations and documentation. The result shows that the strategy undertaken by Department of Culture and Tourism with the branding team of Aceh has been going well, especially in the marketing communication activity. It was marked with a plenty of program related to the implementation of marketing, either using print media, electronic media, billboards, and internet media, especially social media. However, in the branding activity, there are actually some obstacles should be faced, such as the industry player which is less cooperative to provide halal certification for an aprecondition for halal tourism, lack of budget allocation, and the low awareness of public participation. Therefore, more socialization is needed for the players of tourism industry and also the community to raise their awareness and responsibilty in order to jointly support the development of Aceh tourism.
Ultisols have poor soil characteristics, yet biochar is one of the technologies that can be applied as a soil enhancer to improve the soil quality. Biochar has succeeded in improving soil quality, through improving soil physical, chemical, and biological properties. This research aimed to improve the quality of soil chemical properties and growth of maize plant, as well as to find a combination between biochar type and dosage of biochar that is able to improve the chemical properties of Ultisols and/or the growth of maize plant. This research was conducted at the Greenhouse and Soil Science Laboratory, Faculty of Agriculture, University of Lampung. This study used a randomized block design (RBD) arranged in factorial with 3 factors and 3 replications. The first factor was the soil layer (topsoil and subsoil), the second factor was the type of biochar (biochar of cocoa shell and biochar of oil palm shell), and the third factor was the biochar dosage (0, 10%, 20%, and 30% of 10 kg of oven dry weight soil). The results showed that (1) the application of biochar from the cocoa shell and oil palm shell on Ultisols improved some parts of soil chemical properties, namely CEC, organic C, and Kexc, (2) application of biochar from the cocoa shell and oil palm shell on Ultisols increased the plant height, the number of leaves, and the dry weight of maize, (3) application of biochar from the cocoa shell at a dosage of 20% was significantly improved CEC of Ultisols (4) application of biochar from the cocoa shell in top soil at a dosage of 30% significantly improved the soil organic C of Ultisol, (5) application of biochar from cacao shell at a dosage of 30% was significantly improved Kexc, (6) application of biochar from oil palm shell at a dosage of 10% significantly increased maize plant growth.
