13 MarWordPress 4.2 Beta 1

WordPress 4.2 Beta 1 is now available!

This software is still in development, so we don’t recommend you run it on a production site. Consider setting up a test site just to play with the new version. To test WordPress 4.2, try the WordPress Beta Tester plugin (you’ll want “bleeding edge nightlies”). Or you can download the beta here (zip).

4.2 is due out next month, but to get there, we need your help testing what we’ve been working on:

  • Press This has been completely revamped to make sharing content from around the web easier than ever. The new workflow is mobile friendly, and we’d love for you to try it out on all of your devices. Navigate to the Tools screen in your WordPress backend to get started (#31373).
  • Browsing and switching installed themes has been added to the Customizer to make switching faster and more convenient. We’re especially interested to know if this helps streamline the process of setting up your site (#31303).
  • The workflow for updating and installing plugins just got more intuitive with the ability to install or update in-place from the Plugins screens. Try it out and let us know what you think! (#29820)
  • If you felt like emoji were starkly missing from your content toolbox, worry no more. We’ve added emoji support nearly everywhere, even post slugs

WACANA KONSERVASI TANAMAN

Praktik, Pendidikan, Keindahan

Syekhfani

Green Roof Garden, adalah suatu teknologi konservasi estetika tanaman yang disiapkan sebagai objek untuk penelitian dan pendidikan, dikembangkan dalam bentuk laboratorium hidup.

Wacana konservasi tanaman Green Roof Garden, sangat tepat dikembangkan terutama dalam konservasi plasma nuthfah spesifik lokasi, sekaligus memberikan daya tarik sebagai wisata pendidikan.

Berikut, disajikan kutipan dari website http://www.slowlife-exhibit.org/, semoga dapat menjadikan inspirasi untuk kita semua.

TINJAUAN

The Daniel F. and Ada L. Rice Plant Conservation Science Center features a green roof that underscores the Garden’s commitment to plant conservation. Combining practical benefits with aesthetic appeal, the Green Roof Garden also provides an opportunity for research and education, serving as a living laboratory.

The Plant Science Center’s Green Roof Garden serves as an outdoor classroom for thousands of Garden visitors annually; the 16,000-square-foot green roof is accessible to the public via a grand staircase, and an overlook with interpretive panels educates visitors about all aspects of rooftop gardens.

Two distinct areas serve specific functions: the Ellis Goodman Family Foundation Green Roof Garden South features regional and national native plants, many of which are not currently used as rooftop plants; the Josephine P. & John J.

Louis Foundation Green Roof Garden North features a mix of plants known as good green roof plants, plus native and exotic plants that have potential for green roof use. Generally, the plants are sun loving, drought tolerant, have a shallow root system, and can withstand windy conditions.

Check out our blog articles on the green roof garden.

How the Science Works

Green roofs are becoming increasingly popular, but little research has been done to determine which plants are best suited for this extreme environment. The Garden’s evaluation of plants atop the Daniel F. and Ada L. Rice

Plant Conservation Science Center is the largest, most encompassing such trial in the country.

Approximately 40,000 plants representing 200 different species and cultivars are currently under evaluation within three different soil levels (four, six, and eight inches deep) on the 16,000-square-foot green roof.

All of the plants are scientifically evaluated for effectiveness in the semi-intensive roof garden environment.*

This living laboratory is outfitted with equipment to monitor soil moisture, wind and light levels, and temperatures in the various layers of the plantings.

Scientists monitor plant health, aesthetics, and survivorship of plants, ultimately recommending plants that are low-maintenance, absorb water and nutrients from rainfall (lessening runoff into storm sewers), and cool the building below (lessening energy use), while providing an aesthetic retreat.

Plants’ performances in 30 characteristics are tracked for a minimum of four years before staff assess their suitability. Results are shared through the Garden’s Plant

Evaluation Notes, a publication distributed broadly to gardeners and horticultural professionals, and through horticulture and gardening magazines and educational classes and symposia.

Successful plants will be promoted to the green roof industry, both locally and nationally, to ensure that the most appropriate and sustainable plants are used for this unique environment.

How the Beds Work

The planting beds consist of several layers, beginning with a waterproofing layer, two layers of hard foam insulation, a root barrier fabric, a drainage tile to allow water to drain away from the roots, a filter fabric to keep the growing media from clogging the drainage holes, and growing media as the top layer.

Plants are grown in a semi-intensive media—a gravel-like soilless mix especially formulated for roof gardens. Lighter and more porous than soil, it allows water to drain quickly, reducing the weight load on the roof.

Making it possible

The Green Roof Garden at the Plant Science Center was made possible by the generous support of the Ellis Goodman Family Foundation and the Josephine P. & John J. Louis Foundation.

Operational support was provided by the Woman’s Board of the Chicago Horticultural Society facilitates research into which plants are best suited for growing in green roof gardens throughout the Midwest and in similar climates worldwide.

About Green Roofs

Green roofs are an important component of sustainable urban development.

According to the International Green Roof Association (IGRA), public benefits of green roofs include stormwater retention, a decrease in the urban heat island effect, a reduction of dust and smog, natural beauty, and the provision of a new habitat for plants.

Benefits to the building itself include increased roof life, reduced noise levels, thermal insulation, and effectiveness as a heat shield during hot weather.

*There are several types of green roofs: intensive, semi-intensive, and extensive.

Intensive roofs may contain a wide variety of plants (turf, trees, shrubs, and perennials), and even ponds and playgrounds, but they require extensive maintenance, plus permanent irrigation and fertilization.

Extensive roofs are good for sites not intended for use as roof gardens and are well suited to roofs with little load-bearing capacity.

There are few nutrients in the growing medium used in such roofs, which are suitable for less-demanding, low-growing, drought-tolerant plant communities.

The Plant Science Center features a semi-intensive, or intermediate green roof, which falls between the other two types.

It requires more maintenance, costs more, and weighs more than an extensive roof, but it has more design possibilities, and the deeper substrate allows for more plant variety.

10 NovHujan Mulai Turun

FENOMENA ALAM MUSIMAN

Tropika Basah Indonesia

Syekhfani

Indonesia, terletak di zone hujan tropika (tropical rain forest zone), mengenal dua musim, yaitu: penghujan dan kemarau; meskipun ada musim peralihan menjelang awal dan akhir musim tersebut.

Mengikuti siklus iklim (global?), kadangkala terjadi pergeseran waktu awal musim, yang memerlukan antisipasi agar tidak terjadi kerusakan fatal akibat kekeringan atau banjir.

Hujan di awal “musim penghujan” atau di akhir “musim kemarau”, diharapkan cepat turun untuk mencegah agar tanaman tidak kekurangan air dan terganggu pertumbuhannya.

Awal musim penghujan 2014-2015 (di tempat tinggal penulis):

8 Nopember 2014

Hujan yang telah lama ditunggu mulai datang. Diawali cuaca mendung, angin kencang, serta kilat sambung menyambung, akhirnya hujan turun membasahi jalan, rumah dan kebun yang selama ini setiap hari harus disiram agar tanaman tetap tumbuh.

Beberapa hari sebelumnya, sudah ada gejala bahwa hujan akan turun, namun selalu gagal. Mungkin awan pembawa hujan masih belum cukup banyak mengandung butir-butir hujan agar jatuh ke muka bumi. Atau angin menghalau awan hujan tersebut berpindah ke tempat lain.

TEMBOK HIJAU

(GREEN WALL)

 

Tembok Hijau:  “Greening Wall: Ubah Fungsi, Ciptakan Nuansa Hijau”

 

Syekhfani

(foto-foto:  unduhan)

 

Tembok Hijau (Green Wall), rekayasa penciptaan model panorama  “mati” menjadi “hidup” bernuansa hijau menyegarkan;  saat ini sedang  tren di berbagai tempat dan negara, termasuk di negara kita.

Tembok  hijau (green wall), yaitu implikasi sistem “verticulture” (budidaya vertikal) memenuhi permukaan vertikal tembok/dinding gedung/bangunan dengan tanaman (merambat, menempel, menjalar, atau tumbuh pada media pot).

Verticulture memang tidak terlalu sulit dipahami;  yang rumit adalah teknik menjaga tanaman agar memenuhi syarat pertumbuhan  yang diperlukan (air, unsur hara, sinar matahari, ruang tempel, dan sebagainya).

Hal ini dapat dilakukan dengan cara mengubah fungsi fasilitas dan properti yang dipunyai gedung atau bangunan tersebut (misalnya: pemanfaatan air buangan, penggunaan saluran irigasi/drainase,  dan sebagainya). Bisa dipertimbangkan penambahan teknik “fertigasi” (irrigation fertilzizer), pemberian pupuk melalui saluran irigasi.

Lokasi  Tembok Hijau (Green Wall):  Umumnya berada di pusat keramaian kota, sepanjang jalan layang, gedung olah raga (stadion), pusat perbelanjaan, hotel bertingkat, rumah kediaman, dan sebagainya.

LANGKA TAPI MUDAH, BERLIMPAH TAPI SUSAH?!

 

Ada apa sebenarnya?!

 

Renungan: Syekhfani

 

Batu permata itu indah, warna-warni, sulit dicari, tidak dijumpai di semua tempat, LANGKA. Anda kepingin??

Ayo pergi ke toko permata, semua ada, tinggal pilih.

Harga?? Dari paling murah hingga paling mahal… Ada!!

Langka tapi mudah!

 

Nitrogen, 80 persen volume atmosfer terisi oleh gas nitrogen (N2), BERLIMPAH; penyusun khlorofil (bersama C, H, O, dan Mg). Semuanya dibutuhkan untuk hidup dan kehidupan!

Tetapi…  gas N2 tidak dapat langsung diambil oleh  makhluk hidup primer (tumbuhan), terlebih dulu harus melalui mekanisme khusus, diubah menjadi senyawa amida (reduksi) atau nitrat (oksidasi).

Reduksi dilakukan oleh mikroorganisme fiksasi N2 biologis, oksidasi oleh Petir;  baru tersedia dan dapat digunakan oleh makhluk primer (tumbuhan).

Selanjutnya, makhluk primer (tumbuhan) dikonsumsi oleh makhluk sekunder (hewan);  dan   tumbuhan dan hewan dikonsumsi oleh makhluk tersier (manusia).  Lihat:  SOIL:  Memakan dan Dimakan.  Lengkaplah hidup dan kehidupan di dunia ini…

Berlimpah tapi Susah!

 

Apa makna itu semua??!

Tuhan Maha Pencipta dan Maha Tahu,

Melakukan itu semua!

Mengapa?

Apa kamu berpikir?!

…………………………………….

Artinya??

Agar kita menggunakan otak dan kemampuan berpikir yang diberikan olehNya untuk mengungkap artinya!

Untuk menjawab pertanyaan:  apa kamu berpikir??

Apa kesimpulannya??

Fakta bahwa:

Tuhan itu MAHA PENCIPTA DAN MAHA MENGETAHUI!!

…………………….

Bagi yang mau berpikir?!

Berlimpah tapi Susah ~ kebutuhan primer!

Langka tapi mudah ~ kebutuhan sekunder!

Fakta bahwa:

Tuhan itu MAHA  ADIL DAN  BIJAKSANA!

Apa kamu dustakan?!
