Material yang satu ini terbuat dari campuran semen PC dan pasir atau abu batu. Di pasaran, jenisnya ada 2 macam. Ada yang dibuat dengan cetakan manual (menggunakan tangan) dan ada juga yang menggunakan cetakan mesin. Jika dilihat sepintas, keduanya mirip, baik dari ukuran maupun bentuknya. Dari ukuran, kedua batako ini memiliki panjang 36 - 40 cm, tebal 8 - 10 cm, dan tinggi 18 - 20 cm. Keduanya juga memiliki rongga di bagian tengahnya.
Tetapi, jika diperhatikan dengan detail, mereka memiliki perbedaan. Perbedannya bisa dilihat dari kepadatan permukaan batako. Yang kepadatannya paling rapat itu yang hasil cetakan mesin. Dari kualitas, jelas yang cetakan mesin yang paling baik.
Karena memiliki pori yang rapat, batako cetakan mesin kedap air sehingga sangat kecil kemungkinan terjadinya rembesan air. Jika di paku, yang menggunakan mesin juga memiliki daya cengkram yang lebih kuat. Sedangkan batako yang dibuat dengan menggunakan tangan biasanya lebih rapuh.
Adapun secara umum beberapa kekurangan dan kelebihan dari pada batako adalah sebagai berikut :
Kelebihan Batako Sebagai Bahan Bangunan :
Pembuatan mudah dan ukuran dapat dibuat sama.
Ukurannya besar, sehingga waktu dan ongkos pemasangan juga lebih hemat.
Khusus jenis yang berlubang, dapat berfungsi sebagai isolasi udara.
Apabila pekerjaan rapi, tidak perlu diplester.
Lebih mudah dipotong untuk sambungan tertentu yang membutuhkan potongan.
Sebelum pemakaian tidak perlu direndam air.
Kedap air sehingga sangat kecil kemungkinan terjadinya rembesan air.
Pemasangan lebih cepat.
Kekurangan Batako Sebagai Bahan Bangunan :
Mudah terjadi retak rambut pada dinding.
Mudah dilubangi dan mudah pecah karena terdapat lubang pada bagian sisi dalamnya.
Kurang baik untuk insulasi panas dan suara.
Demikianlah artikel kali ini mengenai Kelebihan dan Kekurangan Batako Sebagai Bahan Bangunan. Semoga artikel ini bermanfaat untuk semuanya.

saco-indonesia.com, Petugas Buru Sergap (Buser) Polres Kediri telah berhasil meringkus gembong pencuri sepeda motor (curanmor) asal Kabupaten Tulungagung.
Pelaku yang juga merupakan residivis kambuhan yang sudah lima kali keluar-masuk lembaga permasyarakatan (lapas) di Eks Karesidenan Kediri.
Pelaku yang bernama Khanafi, berusia 35 tahun , berasal dari Kecamatan Boyolangu, Kabupaten Tulungagung. Pelaku ndelosor (tersungkur), setelah kaki kirinya tertembus timah panas petugas.
Kasat Reskrim Polres Kediri, AKP Edi Herwiyanto telah mengatakan, pelaku juga sempat dibuntuti selama tiga hari. Dia baru saja menggasak sepeda motor Yamaha Vega AG 2891 BD di Eks Lokalisasi Waru, Kecamatan Kandat, Kabupaten Kediri, pada 17 Desember 2013 lalu
“Pelaku kita buntuti sejak dari Tulungagung melalui signal HP milik korban yang tertinggal di bawah jog sepeda motor hasil curian,” ujar AKP Edi Herwiyanto di Rumah Sakit Bhayangkara Kota Kediri.
Petugas juga membekuk pelaku di kawasan Kecamatan Kandat. Tetapi karena pelaku melawan, tegas Edi, akhirnya petugas melepaskan tembakan ke arah kaki kirinya.
Seketika pelaku tersungkur. Dia kemudian dilarikan ke RS Bhayangkara Kota Kediri. Saat ini, pelaku juga tengah menjalani operasi pengangkatan proyektil peluru yang bersarang di kakinya.
Edi juga menambahkan, pihaknya tengah mengembangkan kasus pencurian yang dilakukan pelaku. Ia juga memastikan, pelaku juga merupakan gembong curanmor karena sudah lima kali keluar masuk Lapas dalam kasus yang sama.
Masih kata Edi, pelaku ditengarai bagian dari jaringan curanmor yang baru saja diungkap Polda Jatim. Polres Kediri langsung melakukan koordinasi untuk dapat memastikannya.

Even as a high school student, Dave Goldberg was urging female classmates to speak up. As a young dot-com executive, he had one girlfriend after another, but fell hard for a driven friend named Sheryl Sandberg, pining after her for years. After they wed, Mr. Goldberg pushed her to negotiate hard for high compensation and arranged his schedule so that he could be home with their children when she was traveling for work.
Mr. Goldberg, who died unexpectedly on Friday, was a genial, 47-year-old Silicon Valley entrepreneur who built his latest company, SurveyMonkey, from a modest enterprise to one recently valued by investors at $2 billion. But he was also perhaps the signature male feminist of his era: the first major chief executive in memory to spur his wife to become as successful in business as he was, and an essential figure in “Lean In,” Ms. Sandberg’s blockbuster guide to female achievement.
Over the weekend, even strangers were shocked at his death, both because of his relatively young age and because they knew of him as the living, breathing, car-pooling center of a new philosophy of two-career marriage.
“They were very much the role models for what this next generation wants to grapple with,” said Debora L. Spar, the president of Barnard College. In a 2011 commencement speech there, Ms. Sandberg told the graduates that whom they married would be their most important career decision.
In the play “The Heidi Chronicles,” revived on Broadway this spring, a male character who is the founder of a media company says that “I don’t want to come home to an A-plus,” explaining that his ambitions require him to marry an unthreatening helpmeet. Mr. Goldberg grew up to hold the opposite view, starting with his upbringing in progressive Minneapolis circles where “there was woman power in every aspect of our lives,” Jeffrey Dachis, a childhood friend, said in an interview.
The Goldberg parents read “The Feminine Mystique” together — in fact, Mr. Goldberg’s father introduced it to his wife, according to Ms. Sandberg’s book. In 1976, Paula Goldberg helped found a nonprofit to aid children with disabilities. Her husband, Mel, a law professor who taught at night, made the family breakfast at home.
Later, when Dave Goldberg was in high school and his prom date, Jill Chessen, stayed silent in a politics class, he chastised her afterward. He said, “You need to speak up,” Ms. Chessen recalled in an interview. “They need to hear your voice.”
Years later, when Karin Gilford, an early employee at Launch Media, Mr. Goldberg’s digital music company, became a mother, he knew exactly what to do. He kept giving her challenging assignments, she recalled, but also let her work from home one day a week. After Yahoo acquired Launch, Mr. Goldberg became known for distributing roses to all the women in the office on Valentine’s Day.
Ms. Sandberg, who often describes herself as bossy-in-a-good-way, enchanted him when they became friendly in the mid-1990s. He “was smitten with her,” Ms. Chessen remembered. Ms. Sandberg was dating someone else, but Mr. Goldberg still hung around, even helping her and her then-boyfriend move, recalled Bob Roback, a friend and co-founder of Launch. When they finally married in 2004, friends remember thinking how similar the two were, and that the qualities that might have made Ms. Sandberg intimidating to some men drew Mr. Goldberg to her even more.
Over the next decade, Mr. Goldberg and Ms. Sandberg pioneered new ways of capturing information online, had a son and then a daughter, became immensely wealthy, and hashed out their who-does-what-in-this-marriage issues. Mr. Goldberg’s commute from the Bay Area to Los Angeles became a strain, so he relocated, later joking that he “lost the coin flip” of where they would live. He paid the bills, she planned the birthday parties, and both often left their offices at 5:30 so they could eat dinner with their children before resuming work afterward.
Friends in Silicon Valley say they were careful to conduct their careers separately, politely refusing when outsiders would ask one about the other’s work: Ms. Sandberg’s role building Facebook into an information and advertising powerhouse, and Mr. Goldberg at SurveyMonkey, which made polling faster and cheaper. But privately, their work was intertwined. He often began statements to his team with the phrase “Well, Sheryl said” sharing her business advice. He counseled her, too, starting with her salary negotiations with Mark Zuckerberg.
“I wanted Mark to really feel he stretched to get Sheryl, because she was worth it,” Mr. Goldberg explained in a 2013 “60 Minutes” interview, his Minnesota accent and his smile intact as he offered a rare peek of the intersection of marriage and money at the top of corporate life.
While his wife grew increasingly outspoken about women’s advancement, Mr. Goldberg quietly advised the men in the office on family and partnership matters, an associate said. Six out of 16 members of SurveyMonkey’s management team are female, an almost unheard-of ratio among Silicon Valley “unicorns,” or companies valued at over $1 billion.
When Mellody Hobson, a friend and finance executive, wrote a chapter of “Lean In” about women of color for the college edition of the book, Mr. Goldberg gave her feedback on the draft, a clue to his deep involvement. He joked with Ms. Hobson that she was too long-winded, like Ms. Sandberg, but aside from that, he said he loved the chapter, she said in an interview.
By then, Mr. Goldberg was a figure of fascination who inspired a “where can I get one of those?” reaction among many of the women who had read the best seller “Lean In.” Some lamented that Ms. Sandberg’s advice hinged too much on marrying a Dave Goldberg, who was humble enough to plan around his wife, attentive enough to worry about which shoes his young daughter would wear, and rich enough to help pay for the help that made the family’s balancing act manageable.
Now that he is gone, and Ms. Sandberg goes from being half of a celebrated partnership to perhaps the business world’s most prominent single mother, the pages of “Lean In” carry a new sting of loss.
“We are never at 50-50 at any given moment — perfect equality is hard to define or sustain — but we allow the pendulum to swing back and forth between us,” she wrote in 2013, adding that they were looking forward to raising teenagers together.
“Fortunately, I have Dave to figure it out with me,” she wrote.
