Judul: Coastal Vulnerability Mapping of Tsunami using Geographic Information System in Buleleng Regency, Bali Province
Abstrak: Bali merupakan salah wilayah yang dinyatakan rawan bencana karena memiliki posisi geografis yang diapit oleh dua sumber gempa berupa zona subduksi dan back-arc thrust yang menjadi potensi timbulnya tsunami di wilayah Bali. Penelitian ini bertujuan untuk mengidentifikasi dan memetakan tingkat kerawanan pantai terhadap tsunami di Kabupaten Buleleng, Provinsi Bali. Peta kerawanan pantai dibuat dengan metode tumpang susun (overlay) beberapa parameter penentu kerawanan menggunakan Sistem Informasi Geografis (SIG). Parameter yang digunakan yaitu elevasi daratan, kemiringan lahan, penggunaan lahan, jarak dari pantai, dan jarak dari sungai. Tingkat kerawanan pantai terhadap tsunami di Kabupaten Buleleng terbagi menjadi lima kelas kerawanan, yaitu sangat aman (R1) dengan luas sebesar 35.466,9 ha, aman (R2) dengan luas sebesar 70.485,0 ha, agak rawan (R3) dengan luas sebesar 17.645,0 ha, rawan (R4) dengan luas sebesar 6.903,3 ha, dan sangat rawan (R5) dengan luas sebesar 438,9 ha, Bali is one of the areas that prone to disasters because it has geographical position that is flanked by two earthquake sources in the form of subduction zone and back-arc thrust which is potential for a tsunami to occur in the Bali region. This research aims to identify and map the level of coastal vulnerability to the tsunami in Buleleng Regency, Bali Province. The map was carried out using the method of Geographic Information System (GIS). The parameters used in analyzing the level of tsunami vulnerability were land elevation, land slope, land use, distance from the beach, and distance from the river. The level of coastal vulnerability to tsunamis in Buleleng Regency was grouped into five classes of vulnerability, namely very safe (R1) with an area of 35,466.9 ha, safe (R2) with an area of 70,485.0 ha, moderately vulnerable (R3) with an area of 17,645, 0 ha, vulnerable (R4) with an area of 6,903.3 ha, and very vulnerable (R5) with an area of 438.9 ha.

Judul: Mapping the Level of Coastal Vulnerability to Tsunami Disaster on the South Coast of Cilacap Regency, Central Java
Abstrak: Wilayah pantai selatan Kabupaten Cilacap termasuk salah satu wilayah yang mempunyai probabilitas yang tinggi dipengaruhi bencana gempa bumi dan tsunami. Hal ini disebabkan posisi wilayah Kabupaten Cilacap yang sangat dekat dengan pertemuan Lempeng Indo-Australia dan Lempeng Eurasia. Penelitian ini bertujuan untuk mengidentifikasi, memetakan dan menganalisis penyebaran tingkat kerentanan tsunami di wilayah pantai selatan Kabupaten Cilacap, Jawa Tengah. Peta kerentanan tsunami dibuat menggunakan Sistem Informasi Geografis (SIG) dengan metode tumpang susun (overlay) dengan lima parameter, yaitu elevasi daratan, kemiringan lahan, jarak dari garis pantai, jarak dari sungai, dan penggunaan lahan. Penelitian dibagi menjadi dua tahap yaitu tahap pengumpulan serta pengolahan data dan tahap survei lapang yang dilakukan di 4 kecamatan yaitu Kecamatan Cilacap Selatan, Kecamatan Cilacap Utara, Kecamatan Kesugihan dan Kecamatan Adipala. Klasifikasi tingkat kerentanan tsunami dibagi menjadi lima kelas yaitu sangat rendah dengan luas wilayah sebesar 268 ha (0,25%), rendah dengan luas wilayah sebesar 18.708,94 ha (17,16%), sedang dengan luas wilayah sebesar 54.510,29 ha (50%), tinggi dengan memiliki luas wilayah sebesar 33.711,67 ha (30,92%) dan sangat tinggi dengan luas wilayah sebesar 1.815,90 ha (1,67%)., The southern coastal area of Cilacap Regency is one of the areas that has a high probability of being affected by earthquakes and tsunamis. This is due to the position of the Cilacap Regency area which is very close to the meeting of the IndoAustralian Plate and the Eurasian Plate. This study aims to identify, map and analyze the distribution of tsunami vulnerability levels in the southern coastal area of Cilacap Regency, Central Java. The tsunami vulnerability map was created using the Geographic Information System (GIS) with the overlay method using five parameters, namely land elevation, land slope, distance from the coastline, distance from the river, and land use. The research was divided into two stages, namely the data collection and processing stage and the field survey stage carried out in 4 subdistricts, including the Sub-District of South Cilacap, North Cilacap, and Adipala. The classification of tsunami vulnerability level is divided into five classes: very low with an area of 268 ha (0,25%), low with an area of 18.708,94 ha (17,16%), medium with an area of 54.510,29 ha (50%), high with an area of 33.711,67 ha (30,92%) and very high with an area of 1.815,90 ha (1,67%).

Judul: Produksi Kromium Organik dari Fungi serta Peranannya bagi  Aktivitas Fermentasi Rumen
Abstrak: Organic chromium has higher availability than inorganic chromium sources. One of organic Cr h w n is Cr inoorporated to protein fungi. Info~tion about the best fungi or m i ~ s usmed in organic Cr production is still limited Tbus, this expabent was comlwted to study about organic chmium production using cliff- kind of fungi as its carrier, and and evaluate its effects on rumen' fermentation activity. The eqmhtnt consist of two steps. Orgatllc Cr production was c o n d d with a 4x3 factwid Compldy Randomized Design with 3 replication Four fungi used as courier in organic Cr production as first factor were S a c ~ ~ceerevsisia e, AspergilIta o w e , M izopk 0- a d" mgi tape". Second factor was level of chromium addition (500, 1000 dan 1500 mg/kg). Effects of organic chcmium supp1em4on on rumen fermentation activity measured with in vim technique, using Raudomhd Blmk Design with 13 merits and 3 replication. Addition of 1000 rn@g Cr gave the highest Cr incorpoxation to fungi protein (484 mgi'kg) and Cr hcqmmtion efficiency (21,06%). Best fungi used as carrier in organic Cr producbon was Rhizoptnrs oryzae which gave the highest Cr incorporation (488 m@g) and inmpmtion efficiency (24,Ph). Supplementation of I mflg organic Cr increased dry matter and organic matter digestibility in a h kid of fungi used as carrier. It tends to incmsad NF& and total VFA w o n . Partial VFA profile s h o d iacreased propionate p d u c t i g which d e a a d methane production atmd increased hexose convertion efficiency in d lmttmats. Suggested organic Cr wed was 1 m@gg Each h g i used as carrier in o ~ c C r a s u t t e d ~ e f f e c t s m n u n e n f ~ ~ ~ a c t i v i t y , b ~ ~ ~ no m e result showed. It could be concluded that wether Sawhmyces cerevt;piae, AsprgiZIus mywe, MRophus o w e or "IT@ tape" could be US& as carrier in organic Cr pdwt~on
