Banjir merupakan bencana alam yang menjadi langganan beberapa kota besar di Indonesia, ketika memasuki musim penghujan. Oleh sebab itu banyak pihak yang mengembangkan flood early warning system (FEWS), seperti yang dikembangkan oleh BPPT di aliran sungai Cibongas. Seiring berjalannya waktu dalam pengimplementasian alat tersebut perlu dilakukan pengecekan dan perbaikan, untuk memastikan hasil pengukuran sensor pendeteksi curah hujan dan ketinggian permukaan air sungai tetap presisi dan dapat terkirim ke server scara berkala menggunakan komunikasi GSM. Pengecekan dan perbaikan dibagi menjadi dua bagian, system dan fisik. Secara system dilakukan penggantian data logger yang telah disiapkan sebelumnya dimana di dalamnya sudah diperbaharui firmware, card I/O, baterai RTC, fuse, dan SIM card regular operator baru dengan sistem pembayaran pasca bayar. Peraturan baru mengenai pembatasan user dalam memiliki jumlah SIM card maksimal 3 buah saja. Secara fisik pengecekan dan perbaikan alat disebabkan oleh dua penyebab, faktor alam dan faktor manusia. Faktor alam rumput tinggi yang perlu dipotong secara periodik, lumut menutupi alat sensor curah hujan perlu dibersihkan juga, sarang serangga yang menutupi sensor sonar juga perlu dibersihkan dan karat pada gembok diminimalisir dengan disemprotkan WD40. Faktor manusia yang tidak bertanggung jawab memasukkan batu kedalam sensor curah hujan dimana perlu dibersihkan dan yang mengendurkan ulir antena dimana perlu di kencangkan lagi ulirnya.Diperlukan sinergitas dalam menjaga alat FEWS ini, baik dari segi menyikapi faktor alam, oknum yang tidak bertanggung jawab, dan teknis peralatannya, supaya manfaatnya dapat dinikmati masyarakat banyak dan meminimalisir jatuhnya korban jiwa maupun harta.

Floods are the most common disaster in Indonesia. Among various flood types, pluvial flood is the least studied one. Simple rain water harvesting system using cistern/barrel and water tank possess the potential to reduce runoff from roofs and help alleviate the severity of pluvial flooding. The purpose of this study was to simulate the application of simple rain water harvesting in reducing surface runoff from roof surfaces in the study area within the sub Basin of Pesanggrahan. Among all the data that need to be collected were the number of houses and area of roof cover in the study area, as well as 10 years rainfall data. Number of houses per block were collected during a field survey while the estimation of roof area was conducted using a web-based software, i-Tree Canopy. From this simulation, scenario 1 (800-liter water drums), has the potential to reduce surface runoff from the roofs within the range of 6.12 to 9.07% (January) and between 5.08 to 7.49% (February). Meanwhile scenario 2 (2000-liter water tank) has the potential for surface runoff reduction which ranges between 15.30 to 22.67% (January) and between 12.64 to 18.73% (February). On the other hand, the potential to delay the initial surface runoff time using scenario 1 ranged from 3.7 to 5.5 minutes (January) and between 3.1 to 4.5 minutes (February). Meanwhile scenario 2 has a potential to delay the initial surface runoff time from 9.3 to 13.7 minutes (January) and between 7.6 to 11.3 minutes (February).

ABSTRACTThe meeting of the 3 world plates, the Eurasian Plate, the Indo-Australian Plate, and the Pacific Plate in eastern Indonesia, caused a high potential for earthquake and tsunami events in the area. The frequency of tsunami events in eastern Indonesia including West Papua Province is quite large. Tsunamis are mostly caused by earthquakes originating from the sea, but can also be triggered by submarine landslides, volcanic eruptions at sea, gas extrusions, celestial bodies, nuclear explosions and other generating sources. With the high potential of tsunamis in West Papua Province, tsunami hazard and risk maps are urgently needed to become a reference in the development planning process and tsunami disaster risk reduction activities that are more effective, efficient and integrated to reduce the possible impact of victims. The danger of a high tsunami in West Papua Province which has a far enough landward direction is on the coast of Sorong City, Sorong District, South Sorong District, Bintuni District and north of Fakfak District (Bomberay Sub-District). Based on the area of high-risk areas, Bintuni District is the district that has the widest high-risk area, with an area of 116,728 Ha or 5.61% of the total area of the Bintuni District, while Tambrauw District is the district with the smallest high risk area of 2,076 Ha or 0,32% of the total area. The only district that does not have a tsunami threat because it is not in the coastal area is Maybrat District.Keywords: tsunami, West Papua, hazard, risk, risk reduction ABSTRAKPertemuan 3 lempeng dunia, Lempeng Eurasia, Lempeng Indo-Australia, dan Lempeng Pasifik di Indonesia bagian timur, menyebabkan potensi tinggi kejadian gempa dan tsunami di daerah tersebut.

The threat of abrasion even though comes as a slow onset process, but it is certainly and can disrupt the interests of the community. One of the areas that threaten by abrasion is Banggai Kepulauan Regency. To find out how big the threat of abrasion and it’s alternative handling, An abrasion hazard analysis has been carried out based on the calculation of 3 main parameters obtained from secondary data and some of them are detailed by field observations, namely wave height parameters and routinity level, coastal rock / sediment composition, and coastal slope . The results showed that the total coastal length which has a high hazard level is 250.87 km and the Liang sub-district is a district that has the longest high level of abrasion threat, which is 41.11 km long. The alternative measures for abrasion protection, in addition to the physical construction of abrasion-retaining structures as found in the field, is through the protection of green belts and the prohibition of the establishment of houses on abrasive coastal areas.
磨损的威胁虽然是一个缓慢的过程,但它肯定会破坏社区的利益。Banggai Kepulauan Regency是受到磨损威胁的地区之一。为了了解磨损的威胁有多大以及如何应对,本文通过对二次数据中3个主要参数的计算进行了磨损危害分析,其中一些参数通过现场观测进行了详细的计算,即浪高参数和常规水平、海岸岩石/沉积物组成、海岸坡度。结果表明:高危级海岸带总长度为250.87 km,梁街道是高危级海岸带最长的区域,长41.11 km;保护磨损的替代措施,除了实地发现的实际建造防磨损结构外,是通过保护绿化带和禁止在磨损的沿海地区建立房屋。

Landslides are the third most frequent disaster in Indonesia. One of these landslides occurred on March 10, 2017 in residential area of Jatiradio, Cililin Village, Cililin Sub-District, West Bandung Regency, West Java Province. Post-incident investigations have produced information regarding the characteristics of the area and recommendations for disaster mitigation. At present it is known that there are still problems left unsolved in the area that need to be mitigated. The purpose of this study is to identify those unsolved problems at the study site and formulate solutions to the problem using a soil bioengineering approach. Among all the data that need to be collected are the condition of both existing vegetation and subsurface profile on the former landslide slopes at the study site. Data from the observations were then analyzed to produce recommendations regarding the application of soil bioengineering at the study site. From this study, pine trees (Pinus merkusii) is recommended to be planted on the slopes and areas around the rock gabions. This type of vegetation has fulfilled four pre-determined criterias related to the function of slope protection and groundwater regulation for this particular area and is considered suitable to be applied to the study site.

Di dalam standar perencanaan bangunan tahan gempa, disebutkan bahwa gedung yang aman gempa harus memenuhi beberapa kriteria yang dapat dikaji saat gedung sudah dibangun. Beberapa kriteria dapat diperiksa dengan melakukan kajian detil pada gedung. Ada tiga kriteria yang dapat digunakan untuk memeriksa apakah suatu struktur terbangun sudah sesuai dengan standar yang dipersyaratkan. Kriteria itu adalah dimensi kolom, kapasitas kolom, dan periode getar struktur. Dengan melakukan kaji kuat tekan beton, kaji tulangan dalam kolom dan balok, serta pemodelan numerik struktur gedung, maka ketiga kriteria di atas dapat dikaji dan dibandingkan dengan persyaratan di dalam standar perencanaan bangunan tahan gempa. Dalam makalah ini disampaikan kegiatan kajian pada sebuah gedung bertingkat untuk mengetahui kesesuaian struktur gedung dengan persyaratan yang ada dalam standar.

Banjir secara ekologis merupakan peristiwa fisik yang terjadi di dalam lingkungan hidup manusia. Keterbatasan lahan yang tidak dapat menampung pembangunan di wilayah Jakarta, memicu pembangunan di daerah sekitar aliran sungai. Pembangunan di daerah sekitar aliran sungai telah mengubah pola penggunaan lahan. Daerah sekitar sungai merupakan dataran banjir sehingga jika daerah tersebut dibangun menjadi tempat tinggal ataupun permukiman maka permukiman tersebut akan terkena dampak jika air sungai meluap dan menyebabkan banjir. Wilayah Jakarta dilewati oleh 13 sungai yang sering meluap pada musim hujan termasuk Kali Angke dan Pesanggrahan. Penggunaan lahan pada DAS Angke-Pesanggrahan sangat mempengaruhi terjadinya banjir di DAS Angke - Pesanggrahan. Semakin banyak area terbangun pada DAS tersebut maka area penyerapan air juga semakin sedikit sehingga membuat air di Kali Angke dan Pesanggrahan meluap dan menyebabkan banjir. Sehingga perlu adanya klasifikasi tipe zona pemukiman dan juga beberapa metode penyerapan air seperti biopori dan sumur resapan sebagai salah satu cara untuk reduksi risiko banjir.

Kabupaten Kampar mempunyai potensi lahan gambut sekitar 191.363 ha. Sekitar separuh luasan merupakan gambut tipis, sedangkan sisanya bervariasi dari mulai gambut sedang hingga gambut dalam. Saat ini gambut di Kabupaten Kampar sudah dikelola untuk kawasan budidaya, baik untuk tanaman pangan maupun tanaman perkebunan dan HTI. Permasalahannya adalah di Kabupaten Kampar belum tersedianya data detil mengenai luas dan sebaran sumberdaya lahan gambut sebagai acuan rencana perlindungan dan pengelolaannya. Tujuan studi ini adalah identifikasi luas dan sebaran lahan gambut di Kabupaten Kampar, Provinsi Riau. Hasil studi menyimpulkan bahwa Kabupaten Kampar memiliki 5 (tujuh) tipe lahan gambut, yaitu Sikladipanjang (SLP) 125.920,92 ha, Benjah Bekasih (BBK) 17.960,79 ha, Gambut (GBT) 19.829,41 ha, Klaru (KLR) 9.120,14 ha, dan Mendawai (MDW) 18.532,15 ha. Sebaran lahan gambut tersebut berdasarkan lokasi administrasi dibagi menjadi 5 Klaster Kawasan Gambut yaitu: Siak Hulu (17.191,40 ha), Perhentian Raja (63.290,70 ha), Kampar Kiri Hilir (8.162,05 ha), Tambang (26.766,16 ha) dan Tapung (75.953,11 ha).

ABSTRACTDepok City has a function as a water catchment in reducing flooding in Jakarta City and in Depok City itself, the existence of existing sites is very important to be maximized. At present there are only 21 small lake in Depok City whose existence is still maintained. The conditions there each year decrease both in terms of quality and quantity. There are 6 small lake in Cimanggis subdistricts, namely: Situ Gadog, Situ Pedongkelan, Situ Rawa Kalong, Situ Tipar, Situ Jemblung, and Situ Rawa Gede, which as a whole have an area of 32.4 Ha. To maintain small lake preservation in the Cimanggis sub-district, damage risk reduction is urgently needed to sustain the small lake's existence in a sustainable manner. There are 5 variables of community participation in damage risk reduction in Cimanggis sub-district. Five variables to measure the level of community participation are community participation in the form of thoughts, community participation in the form of property, community participation in the form of energy, community participation in the form of skills, and community participation in social forms. Keywords: Community participation, small lake, Cimanggis, damage risk reduction
