ABSTRACT This research aims to analyze the condition of seagrass ecosystem to see water quality data of the seagrass habitat and percentage cover of seagrass in the waters of the Pramuka Island, Seribu Islands. The research was conducted over two months from October to November 2014.This research used a descriptive method with field survey approach. The population in this study is the seagrass in Waters Pramuka Island. Determining the location with purposive sampling of the sampling is divided into three stations is North, East and South. Data collection techniques include primary data and secondary data. Primary data is data of seagrass (type, percentage cover and density of seagrass) and data of seagrass habitat environmental parameters (water temperature, current speed, brightness, depth, salinity, substrate, TSS, DO, pH) were obtained by direct measurement in the field, while secondary data include the general state of the research sites. Data analysis techniques used in this study using analysis of community structure of seagrass and water quality analysis. The results showed that seagrass species found in the Pramuka Island there are 6 types of seagrass Cymodocea rotundata, Cymodocea serrulata, Enhalus acoroides, Halophila ovalis, Halodule uninervis, Thalassia hemprichii. Conditions of seagrass in the waters of the Pramuka Island included into the category of less healthy-poor seagrass. At station 1 percentage by 31% classified seagrass less healthy conditions, while the other two stations are stations 2 and 3 belong to the category of the poor condition of seagrass, with each percentage cover of seagrass 19.4% and 20.3%. Of all water quality parameters measured, all the parameters are still in normal circumstances, but there are some parameters whose value is high at some stations TSS and pH value is high at station 2 with a value of TSS 18 mg/l and a pH value of 8.2. Water quality and seagrass communities in station 1 is still in good condition for the growth of seagrass, because at this station is an unspoiled area away from human activity, while the stations 2 and 3 have undergone changes in community structure of seagrass because at this station has several anthropogenic activities that disrupt the lives of seagrass, mostly from human activities such as domestic sewage and hoarding/reclamation, which affects the condition of seagrass at station 2 and 3 are poor seagrass.

ABSTRAK Pembangunan konstruksi di atas tanah gambut akan mendapatkan beberapa masalah geoteknik. Salah satunya adalah terjadinya penurunan (konsolidasi) tanah yang apabila mengalami pembebanan diatasnya maka tekanan air pori akan naik sehingga air pori ke luar yang menyebabkan berkurangnya volume tanah, oleh karena itu akan terjadi penurunan pada tanah. Tujuan dari penelitian ini adalah untuk mengetahui dan membandingkan data hasil pengujian penurunan lapis tanah pada tanah gambut menggunakan metode sand drain dengan Pembebanan Bertahap pada kondisi Single Drain (Pola Segitiga dan Pola Segiempat). Pengujian dilakukan di Laboratorium Mekanika Tanah Universitas Lampung. Sampel tanah yang akan diteliti adalah tanah gambut pada kedalaman 20 cm. Pelaksanaan pengujian dilakukan dalam 2 tahap. Pertama adalah pengujian sifat fisik dan konsolidasi tanah gambut. Kedua adalah pengujian lama waktu pengeringan pada tanah gambut akibat pengaruh metode drainase menggunakan bahan pasir. Data yang didapatkan dari percobaan diolah, dan kemudian hasil perhitungan tersebut ditabelkan dan dibuat grafik. Dari penelitian ini didapatkan: Koefisien konsolidasi (Cv) untuk pola segitiga sebesar 0,00079 cm2/menit dan untuk pola segiempat sebesar 0,0028 cm2/menit, nilai indeks tekanan Cc untuk pola segitiga sebesar 2,5589 dan untuk pola segiempat sebesar 1,0041. Sehingga diambil kesimpulan : (1) Penggunaan metode sand drain dengan pola segiempat ternyata dapat menurunkan tanah lebih cepat daripada dengan pola segitiga (2) Nilai Cv (koefisien konsolidasi) sebelum pembebanan lebih besar daripada setelah pembebanan, sedangkan nilai Cc (indeks pemampatan) sesudah pembebanan lebih besar daripada sebelum pembebanan. Kata Kunci : Gambut, Single Drain, Konsolidasi

ABSTRACT Bandar Lampung is an area in Indonesia which has a high level of Tsunami threat. It is due to the position of Bandar Lampung which is located relatively near the meeting point of Indo-Australian plate dan the Eurasian plate; both are plates are relatively active. Other causes are earthquake threat and the existence of Krakatoa which is potential to generate earthquakes which are followed by a Tsunami. The data analysis showed that the potential Tsunami hazard in the coastal city of Bandar Lampung is the predicted distance run up the marinade tsunami that reached a height of 20 meters above sea level. Potential hazards include four districts, i.e. Bumi Waras District, Panjang District, South Teluk Betung District, and East Teluk Betung District. The research method is Cell-Based modeling, the one using the tool model builder in Arc GIS with 1 meter raster grid analysis, which can show and explain in detail the attributes that exist in the region. From Quick Bird image that has of 0.6 meter resolution, the existing condition of the land use can be clearly seen. The results of the analysis showed the vulnerability of Tsunami in the city of Bandar Lampung. The results showed that Bumi Waras District has the highest vulnerability level at Bumi Waras Subdistrict with an area of 85.62 Ha. Panjang District has the highest level of vulnerability at Pidada Subdistrict with an area of 30.16 ha. South Teluk Betung District has the highest level of vulnerability at Pesawahan Subdistrict with an area of 0,02 Ha. East Teluk Betung District has the highest level of vulnerability at Kota Karang Subdistrict with an area of 32.11 Ha. Keywords: Tsunami disaster, Vulnerability and cell-based modeling
