Judul: Status mikoriza hutan pantai dan hutan mangrove pasca tsunami studi kasus di Nanggroe Aceh Darussalam dan Nias
Abstrak: This research aimed 1) to study status of arbuscular mycrorrhizal fungus (AMF) in mangrove and coastal forest post tsunami disaster, 2) to study the relationship of soil phosphorus content and number of AMF spores and AMF infection of mangrove and coastal forest post tsunami disaster. Research results show that there were variability in spore numbers in the field studied. The spore numbers in mangrove forest were found as 359, 235, 118 and 160 spores per 50 g of soil in Meulaboh, Banda Aceh, Pidie and Nias respectively. Meanwhile, in coastal forest were 587, 297, 265 and 158 spores per 50 g in Meulaboh, Banda Aceh, Pidie and Nias respectively. The root of Rhizophora sp. and Casuarina equisetifolia found colonized by AMF both in mangrove and coastal forest. Number of spores were negatively correlated to soil phosphorus content, however, there were tendency positive correlation between root infection and soil phosphorus content.

Judul: Keanekaragaman Cendawan Mikoriza Arbuskula (CMA) di Hutan Pantai Ujung Genteng, Sukabumi-Jawa Barat
Abstrak: Indonesia is one of the countries that has a megadiversity of microorganisms and has a large area of coastal forests. However, research on microbial diversity particularly AMF as one of the dominant microbes in a coastal forest ecosystems has not been done extensively. The main objective of this research was to study the diversity and distribution of AMF in coastal forest and to analyse effects of salinity on the fungal and plant community at Coastal Forest Ujung Genteng Cape, Sukabumi - West Java. This research was carried out in two parts: field, green house and laboratorium experimental activities. Field experimental activities were conducted for vegetation analysis, collecting of plant root system, rhizosphere soils from tree and pole phase,. seedling of understorey plants for fungal colonization analysis, isolation and identification of AMF and soil characteristics, include salinity. Green house and laboratorium activities were carried out for isolation, identification and colonization analysis of AMF. Field research location was divided into three zones, first zone was 0 – 70 m distance from coastal area (P), second zone was 71 – 140 m distance from coastal area (T), and third zone was 141 m distance from coastal until forest up to area in the center (H). Twenty three AMF species from 45 plant rizosphere were identified. The fungi belong to 5 species of Acaulospora, 2 species of Gigaspora, 13 species of Glomus, 1 species of Paraglomus and 2 species of Scutellospora. Glomus geosporum was the most dominant AMF in the ecosystem with the value of frequency was 16.49% - 23.67%. Glomus etunicatum, Acaulospora foveata, A. longula, A. scrobiculata, A. tuberculata, and Scutellospora auriglobosa were the AMF that had frequency higher than other species but less than G. geosporum in the field. Results from vegetation analysis indicated that Ujung Genteng Coastal Forest had 68 plant species belonging to 40 families. Dysoxylum parasiticum and Piper cf. baccatum were dominant plants in the ecosystem. The plant community measured at the three zones experimental sites were differed. The similarity index value of the plant community (Is) between coastal P) and center (T) area was 35.42%, between center (T) and forest center (H) was 32.53%, and between coastal edge (P) and forest center (H) was 27.04%. There was no correlation between diversity of plant and diversity of AMF onserved. Diversity of AMF were influenced with all interaction environment factors especially salinity. Two species of AMF had a narrow distribution and found only in a rhizosphere of one plant species . Glomus sp 5. found only in Guettarda speciosa rhizosphere and Glomus sp6. in Salacia sp. rhizosphere. Nineteen species were identified from P zone, 17 species from T zone and 14 species from H zone, with the index diversity values of AMF were 0.73 – 6.64, 0.85 – 4.93 and 1.26 – 4.84, respectively. The salinity at Ujung Genteng Cape was falled in moderate degree with the value of 420 – 1735 μs/cm. The salinity influenced the diversity of AMF and plant community structures. Nineteen species were identified from P zone, 17 species from T zone and 14 species from H zone,

Judul: Optimasi formula dan evaluasi mutu  minuman berprotein tinggi berbasiskan isolat protein kedelai dan sweet whey
Abstrak: Kedelai merupakan sumber protein nabati yang mempunyai mutu atau nilai biologi tertinggi. Hal ini dapat dijadikan sebagai salah satu pertimbangan untuk menggunakan kedelai sebagai sumber protein. Pemanfaatan isolat protein kedelai yang merupakan pengolahan lebih lanjut dari kedelai dalam industri pangan kebanyakan hanya terbatas sebagai pengganti protein hewani, seperti dalam industri sosis dan nugget. Padahal penggunaan isolat protein kedelai dalam formulasi minuman cukup berpotensi. Hal ini dapat dilihat dari kelarutan dan dari segi rasa serta komponen yang terdapat dalam isolat protein kedelai dapat dimanfaatkan dalam pembuatan sumber protein dalam bentuk cair. Protein kedelai dikenal paling baik diantara sumber protein nabati lainnya, selain itu asam amino lysine yang biasanya asam amino pembatas dalam pola konsumsi manusia memiliki kadar yang cukup tinggi. Namun protein kedelai ini memiliki kekurangan dalam asam amino yang mengandung sulfur seperti cystein dan methionin. Bahan yang paling sesuai digunakan sebagai komplementer untuk protein kedelai adalah sweet whey protein. Kesesuaian ini dapat dilihat dalam proporsi asam amino dari whey yang dapat saling melengkapi protein kedelai. Selain itu sweet whey juga memiliki aroma khas susu yang dapat menutupi aroma kedelai yang kurang disukai dalam produk turunan kedelai dan sweet whey juga memiliki komponen fungsional yakni immunoglobulin yang bermanfaat bagi tubuh sebagai faktor imun. Pembuatan formulasi minuman berprotein tinggi ini menggunakan persamaan model formula (mixture design) d-optimal scheffe (Cornell, 1984). Model ini menentukan komposisi yang tepat dari 2 atau lebih campuran yang menghasilkan formulasi yang sesuai kehendak tanpa memperhatikan interaksi komponen lain yang dianggap tetap. Untuk mempermudah operasi aritmatikanya, penulis menggunakan software Design Expert 7.1 yang dapat menentukan titik pengujian, analisis dan persamaan formula yang sesuai dengan kehendak. Titik dilakukannya pengujian didapatkan dengan perbandingan Isolat protein kedelai dengan sweet whey adalah 75:25 ;83.33:16.67 ; 87.5:12.5 ; 91.67:8.33 dan 100:0. Setelah diujikan secara organoleptik, bahan baku terbaik adalah Soypro 900ES. Kemudian, bahan baku ini digunakan dalam formulasi, dan didapatkan formulasi optimum pada rasio subtitusi Isolat Protein Kedelai dengan sweet whey sebesar 77.28:22.72. Hasil yang diperoleh dari pengukuran sifat fisiko kimia dan biologisnya adalah Formula Terpilih memenuhi standar kadar abu, protein dan lemak untuk susu bubuk menurut SNI tapi tidak untuk standar kadar air. Produk terpilih memiliki derajat putih yang lebih baik dibandingkan produk sejenis lainnya dipasaran. Dari segi nilai biologi formula terpilih memiliki kecernaan hingga 93,96 %. Total senyawa fenol adalah 129.34/100g formula terpilih dan memiliki aktifitas antioksidan 20.11 setara asam askorbat (AEAC).
