Tips Rahasia Lolos Seleksi Psikotes

Phsicology Test/Tes Psikologi atau psikotes/psikotest sebagai bagian dalam tahapan penerimaan calon pegawai. Keunikan dari tes ini adalah pada “ketidakpastiannya”. Mengapa? Karena faktor dapat memutarbalikan perhitungan logis potensi seseorang. Sebagai contoh, seseorang lulusan perguruan tinggi terbaik di negeri ini dengan IPK : 3 koma dan berpengalaman sebagai asisten dosen, tidak dapat lolos dari lobang jarum ujian psikotes sehingga akhirnya harus berwirausaha karena belum pernah mampu melewati psikotes untuk diterima bekerja di sebuah perusahaan. Memang ini ironi, namun ini fakta. Psikotes memang merupakan fenomena tersendiri bagi para pelamar kerja. Penulis juga pernah menghadapi hal serupa, untuk kemudian harus bangkit melalui proses “learning by doing”. Penulis bukan seorang psikiater maupun phsicology tester, namun beberapa tips yang akan dishare berikut ini, berdasarkan pengalaman penulis ketika menghadapi psikotes, diharapkan mampu membantu mengurangi kegagalan psikotes Anda:

Sore throat

A sore throat is discomfort, pain, or scratchiness in the throat. A sore throat often makes it painful to swallow.
Sore throats are common. Most of the time the soreness is worse in the morning and improves as the day progresses.
Like colds, the vast majority of sore throats are caused by viral infections. This means most sore throats will NOT respond to antibiotics. Many people have a mild sore throat at the beginning of every cold. When the nose or sinuses become infected, drainage can run down the back of the throat and irritate it, especially at night. Or, the throat itself can be infected.
Some viruses can cause specific types of sore throat. For example, Coxsackievirus sometimes causes blisters in the throat, especially in the late summer and early fall. Mononucleosis and the flu can also cause specific viral throat infections.
Strep throat is the most common bacterial cause of sore throat. Because strep throat can occasionally lead to rheumatic fever, antibiotics are given. Strep throat often includes a fever (greater than 101°F), white, draining patches on the throat, and swollen or tender lymph glands in the neck. Children may have a headache and stomach pain.

Why is Biodiversity Important?

Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play.

For example,

And so, while we dominate this planet, we still need to preserve the diversity in wildlife.

A healthy biodiversity offers many natural services

Ecosystems such as the Amazon rainforest are rich in diversity. Deforestation threatens many species such as the giant leaf frog, shown here. (Images source: Wikipedia)

A healthy biodiversity provides a number of natural services for everyone:

  • Ecosystem services, such as
    • Protection of water resources
    • Soils formation and protection
    • Nutrient storage and recycling
    • Pollution breakdown and absorption
    • Contribution to climate stability
    • Maintenance of ecosystems
    • Recovery from unpredictable events
  • Biological resources, such as
    • Food
    • Medicinal resources and pharmaceutical drugs
    • Wood products
    • Ornamental plants
    • Breeding stocks, population reservoirs
    • Future resources
    • Diversity in genes, species and ecosystems
  • Social benefits, such as
    • Research, education and monitoring
    • Recreation and tourism
    • Cultural values

That is quite a lot of services we get for free! Continue reading

What is Sustainable Agriculture?


Agriculture has changed dramatically, especially since the end of World War II. Food and fiber productivity soared due to new technologies, mechanization, increased chemical use, specialization and government policies that favored maximizing production. These changes allowed fewer farmers with reduced labor demands to produce the majority of the food and fiber in the U.S.

Although these changes have had many positive effects and reduced many risks in farming, there have also been significant costs.Prominent among these are topsoil depletion, groundwater contamination, the decline of family farms, continued neglect of the living and working conditions for farm laborers, increasing costs of production, and the disintegration of economic and social conditions in rural communities.

A growing movement has emerged during the past two decades to question the role of the agricultural establishment in promoting practices that contribute to these social problems. Today this movement for sustainable agriculture is garnering increasing support and acceptance within mainstream agriculture. Not only does sustainable agriculture address many environmental and social concerns, but it offers innovative and economically viable opportunities for growers, laborers, consumers, policymakers and many others in the entire food system.

Biodiversity Conservation in terrestrial, marine and aquatic environments.


I have found many organizations in the world including the government and non-government agencies that providing some information about biodiversity conservation in terrestrial, marine and aquatic environments. Some of them have the same needs or the same point of view to conserve what they really love about, such as the aquatic warbler.

The Aquatic Warbler Acrocephalus paludicola is the rarest and the only globally threatened passerine bird found in mainland Europe. The species is classified as Vulnerable at global level and is listed as Vulnerable in the IUCN Red List of Threatened Species. At the European level it is classified as Endangered. It is also included into Annex I of the EU Wild Birds Directive, in Appendix II of the Bern Convention and in Appendix I of the Bonn Convention.

The Aquatic Warbler regularly breeds in Belarus, Germany, Hungary, Lithuania, Poland and Ukraine (irregularly in Russia and Latvia), with major populations in Belarus, Ukraine, and Poland. The breeding distribution is fragmented because of habitat constraints. The species became extinct in Western Europe during the 20th century and has declined dramatically in central Europe. It formerly bred in France, Belgium, Netherlands, former West Germany, former Czechoslovakia, former Yugoslavia, Austria and Italy. Continue reading
