Pressure Equalisation Modules System (PEM)













Pressure equalisation modules (PEM) are vertical pipes that are placed in rows forming matrix along the costline (above figure). The ussage of this system is to stimulate the accretion of sand on certain beaches and slow down the erosion process on other beaches. Cross-shore sand tongue develops in front of each row of the PEM systems to create the same effect as groynes in aresting some of the transported long shore sand, thus building up the sand between the rows. The pipes act as pressure equalizer that equalise the pressure in the groundwater zone and increased circulation of seawater in the coastal profile will take place thus promoting sedimentation.

The PEM system is simple in design but is based on relatively difficult phenomena under the principle of soil drainage. The swash zone is the zone is the area of the beach whare waves crash and run up along the beach slope. The seawater then returns down the beach face but at the same time permeates into the profiles. These mechanism will put the PEM system to provides a faster passage for the water within the vertical profile of the swash zone to drain. During the high tide, the seawater extends further up the beach which means pressure is built up in the layer underneath where there is fresh water tongue originating from the hinterland. The drainage passage created by the PEM system thus equalises the pressure within the upper and the lower profiles.

When the water level is low on the coast during the period from low tide to high tide, the water circulation in the swash zone increases the depositing of materials on the foreshore, thereby building up the beach from the sediment transported along the coast, so that this PEM system is the one of the suitable system in the slowdown of the erosion rate of the beach as well as to protect the beach from severe erosion.

Rusuhan ISA

Tanggal 1 hb Ogos yang lalu KL telah digemparkan dengan rusuhan bagi membantah dan ada yang menyokong ISA. Boleh dikatakan hampir 60% adalah pelajar IPT. Penulis amat tidak bersetuju dengan rusuhan tersebut, apa faedahnya????? bagi para pelajar, apa yang anda nak buktikan???( duit pun pinjam PTPTN atau biasiswa JPA). Rata-rata yang menyertai perhimpunan tersebut adalah orang MELAYU... percayalah, anda semua telah diperkudakan oleh orang-orang politik (BN?? PR???) yang ada agenda mereka tersendiri. Sebagai pelajar IPT anda seharusnya mengkaji rasionalnya menyokong atau membantah, bukan hanya ikut membuta tuli. Penulis percaya sebahagian besar yang menyertai perhimpunan tersebut tidak tahu pun apa itu ISA, malah ada yang tidak tahu maksud ISA itu sendiri. Ketua kepada perhimpunan tersebut mungkin telah dibayar oleh orang-orang politik (BN???PR???) dan jikalau tertangkap sekurang-kurangnya duit tersebut boleh dibayar sebagai ikat jamin mereka, tapi anda yang lainnya dapat apa???? letih?? kepuasan?? keseronokan?? atau pun pengiktirafan??. Percayalah anda tidak dapat apa-apa manfaat selain memberi keuntungan kepada orng-orang politik (BN???PR???). Kerajaan sebelum itu telah pun menyatakan bahawa mereka sedang mengkaji samada akan memansuhkan atau mengekalkan ISA, jadi buat apa kalian semua berhimpun???. Peniaga adalah golongan yang paling teruk mengalami kerugian, semuanya gara-gara kalian yang ternyata BODOH menyertai perhimpunan tersebut. Ingatlah , mereka juga ingin mencari rezeki untuk menyara keluarga. Imam Syafie Rahimahullah pernah berpesan kepada anak muridnya bahawa jangan sesekali bertaklid iaitu mengikut membabi buta, ini lah kelemahan orang melayu islam pada hari ini, anda yang menyertai perhimpunan tersebut seharusnya mengkaji rasional tindakan anda dan implikasi tehadap negara, orang ramai, peniaga etc. bukan hanya semata-mata mengikut perasaan yang nyatanya didorong oleh orang-orang politik (BN???PR???). Ini bukan caranya untuk membantah atau menyokong ISA. Tahukah anda perhimpunan tempoh hari dianjurkan oleh orang-orang politik (BN???PR???) lebih kepada untuk mengekalkan survival politik golongan tertentu dan bukanya ingin sangat menghapuskan ISA, cuba kalian kaji betul-betul, ini mungkin dirancang oleh badan perisikan (CIA??? Mossad???SID???) sepertimana yang berlaku di iran sekarang, Mosavi secara jelas telah memperoleh sokongan CIA bagi menjatuhkan kerajaan pimpinan Ahmadinejad yang menang menerusi pilihan raya yang sah dan ini tidak mustahil boleh berlaku di negara ini. Lagi satu perkara, penulis yakin bahawa sesiapa pun memerintah Malaysia (BN???PR???) akan tetap mengekalkan ISA, ini kerana ISA merupakan satu mekanisma cegah rintang yang paling berkesan untuk menjamin survival politik orang-orang politik ini (BN???PR???), percayala...Akhir kata penulis ingin mencadangkan bahawa elakkan lah sebarang domonstrasi seperti ini kerana ia hanya menguntungkan golongan yang berkepentingan sahaja, daripada kalian berhimpun untuk menentang ISA kan lebih baik berhimpun bagi menentang kenaikan harga barang ke, kenaikan minyak ke, menentang orang islam berjudi ke, menentang orang islam buat maksiat ke kan lagi elok. FIKIR-FIKIRKANLAH SAUDARA SEAGAMA KU...

Deadly Weapon of Malaysian Armed Forces






















































The above pictures show the latest most deadly weapon in Malaysian Armed Forces. The question is "are we going to battle with our neighbours??". The answer is relative to every person's point of view. Have you heard about the famous malay proverb: "standby the umbrella before the rain"? Now i try to answer the above question with my point of view.

Recently there are a few situations in this region that need us to give a priority in the modenization of our armed forces. Back to 1990's, just after the communist rebellion surender, our armed forces seriously need the modernization in order to enter the new era of the war which is conventional war. Realizing to that matter our government through the Ministry of Defence was decided to give the full attention to the modernization programme for our armed forces.


The 90's saw the arrival of the BAE Hawk Mk108/208 which replaced the A-4C skyhawk followed by the MiG-29N/NUB in 1995 to take on the air superiority role, then the delivery of the F/A-18D Hornet in 1997 to provide the all weather interdictor capability and finally the eighteen Su-30MKMs for delivery in 2007 to fulfill a requirement for an initial order batch of multi-role combat aircraft (MRCA).


In 1996, Royal Malaysian Navy (RMN) planned to acquire a total of 27 New Generation Patrol Vessels (NGPV) to full fill its future requirement. The Germany Blohm + Voss MEKO 100 based design was selected and a contract of 6 NGPVs was signed in 2003.

The Malaysian Minister of Defence also announced that Malaysia would be buying 2 frigates from the United Kingdom. On 20 July 2006 the Clyde shipyard has won a contract to help build two of second batch of Lekiu class frigate for Malaysia. The two frigates will be completed at Labuan Shipyard and Engineering in Malaysia as a condition of the deal and the new frigates are said to be benefit from the latest U.K.Type 45 (T45) destroyer technology transfer. In 2006 The Ministry of Defence was signed for the two scorpene class submarine from the DCNS, and its Spanish partner, Navantia for the built of these two most modern submarine, the resources said these two submarine will be armed with Blackshark wire-guided torpedoes and Exocet SM-39 sub-launched anti-ship missiles and belived that this is the only submarine in this region that can launch the missile to the surface.

The Malaysian army not being neglecting from receiving the new deadly weapon,delivery of 48 PT-91M main battle tanks from Poland may enhance the capability of the army besides adding some 28 units of modern South African G5 Mk III 155 mm howitzers and 36 units of Astros MRLS from Brazil which delivery was completed in 2007 will at least give the uncomfortable feelings to the nearby neighbours.

As the conclusion, all these entire deadly weapon will make our enemy think twice to do the invasion on our beloved country. We are not going to provoke anybody but the readiness of the armed forces perhaps can creating the "scaring factor" to our enemy.
