Penelitian ini merupakan bagian dari Ekspedisi Widya Nusantara 2016 yang bertujuan untuk merekonstruksi dinamika iklim dengan memperhatikan kondisi keanekaragaman morfologi polen, spora dan keanekaragaman flora sekitar perairan Selat Sumba pada Kala Holosen. Sedimen diambil menggunakan penginti gravitasi pada Kapal Riset Baruna Jaya VIII pada kedalaman kolom air 1283 m dengan panjang inti 243 cm. Kedalaman yang diamati yakni 0-102 cm dengan interval penyamplingan adalah 5 cm, sehingga diperoleh 22 sub-sampel. Jenis sedimen yang dominan adalah lanau sedangkan pasir hanya mendominasi bagian permukaan. Berdasarkan hasil analisis kuantitatif palinologi, lapisan dibagi menjadi empat zona dan untuk mengetahui umur dari tiap lapisan sedimen digunakan datum Foraminifera Globigerinella calida calida. Zona I dengan perkiraan umur 5662-7550 tahun yang lalu memiliki karakteristik, jenis Arboreal Pollen (AP) yang lebih dominan yakni Cupressaceae, sedangkan jenis spora yang dominan adalah Polypodiaceae dan Acrostichum aureum. Zona ini diintepretasikan beriklim panas dan basah, dengan nilai Pollen Marine Index (PMI) 100 dan indeks keanekaragaman adalah 0,35. Zona II berumur 4530-5662 tahun yang lalu dengan kehadiran Arboreal Pollen (AP) yang lebih dominan adalah Casuarinaceae dan spora Polypodiaceae, sehingga diintepretasikan iklimnya adalah panas dan basah, PMI = 105 dan Indeks keanekaragaman 1,56. Zona III berumur 2265-4530 tahun terdapat Arboreal Pollen (AP) yakni Anonaceae 43,75 % dan Spora yakni Polypodiaceae 33 %, sehingga diintepretasikan beriklim panas dan basah, PMI= 118 serta Indeks keanekaragaman 2. Zona IV adalah lapisan paling muda berumur 2265-sekarang memiliki persentase Arboreal Pollen (AP) yang lebih dominan yakni Anonaceae sebanyak 44% dan adanya peningkatan kehadiran spora yakni taksa Acrostichum aureum sebanyak 41,2 %, PMI = 128,25 dan memiliki Indeks keanekaragaman 1. This research is part of Widya Nusantara Expedition 2016 aiming to reconstruct the dynamics of the climate by considering the condition of morphology of pollen, spore and the diversity of flora around the waters of the Sumba Strait in the time of Holocene. The sediment was taken using gravity corer on Research Vessel of Baruna Jaya VIII at a water column depth of 1283 m with a core length of 243 cm. The depth was observed at 0-102 cm and the sampling interval of 5 cm, so 22 sub-samples were obtained. The dominant type of sediment was silt and sand dominates on the surface. Foraminifera Globigerinella calida calida is used as a datum to determine relative age. Based on the results of the analysis, the layers are divided into four zones. Zone I with an estimated age of 5662-7550 years ago has a more dominant Arboreal Pollen (AP) type characteristic, namely Cupressaceae, while the dominant spores are Polypodiaceae and Acrostichum aureum. This zone is interpreted as a hot and wet climate, with a Pollen Marine Index (PMI) 100 and a diversity index of 0.35. Zone II was 4530-5662 years ago with the more dominant Arboreal Pollen (AP) presence being Casuarinaceae and Polypodiaceae spores, so the interpreted climate was hot and wet, PMI = 105 and the Diversity Index 1.56. Zone III aged 2265-4530 years. There are Arboreal Pollen (AP) i.e. Anonaceae 43.75% and Spores i.e. Polypodiaceae 33%, so it is interpreted as hot and wet climate, PMI = 118 and Diversity Index 2. Zone IV is the youngest layer of 2265 – now. It has the most dominant percentage of Arboreal Pollen (AP), Anonaceae as much as 44% and an increase in the presence of spores i.e. Acrostichum aureum taxes as much as 41.2%, PMI = 128.25 and has a Diversity Index of 1.

Sumba merupakan salah satu pulau terluar Indonesia yang terletak di bumi bagian selatan dan berbatasan dengan Samudra Indonesia. Distribusi polen pada sedimen permukaan di Perairan Sumba dilakukan untuk membantu interpretasi efek sedimentasi yang terjadi di daerah fluvial dan laut serta perubahan tumbuhan terestrial. Penelitian ini merupakan bagian dari Ekspedisi Widya Nusantara 2016 yang dilaksanakan pada tanggal 4 – 26 Agustus 2016 menggunakan Kapal Riset Baruna Jaya VIII. Tiga belas sampel sedimen permukaan dianalisis menggunakan metode asetolisis dan swirling. Spektrum polen menunjukkan hubungan antara distribusi polen yang mengendap di sedimen laut dan transportasinya dari daratan. Sebaran polen yang banyak terakumulasi di bagian barat Pulau Sumba menunjukkan adanya pengaruh fluvial dan jarak dari pantai dan kedalaman air. Hasil uji korelasi antara distribusi polen dengan kedalaman dan besar butir (rata-rata dan persentase mud) menunjukkan hubungan yang cukup kuat (r=0,465; r=0,374 dan r=0,443). Meskipun dengan rata-rata tingkat keanekaragaman tumbuhan termasuk dalam kategori rendah (indeks 1,07), distribusi polen dalam sedimen permukaan laut merefleksikan vegetasi lokal di daratan Pulau Sumba. Polen yang paling mendominasi berasal dari Famili Poaceae. Studi ini menjelaskan bahwa rekaman polen dari inti sedimen laut Perairan Sumba mempunyai potensi menjadi alat rekonstruksi perubahan vegetasi di daratan sekitarnya dalam studi variabilitas iklim masa lalu dan masa yang akan datang. Sumba, one of the outer Indonesian island, is located in the southern hemisphere and bordered by the Indonesian Ocean. The distribution of pollen in marine sediments offshore the Sumba Waters has been investigated to help interpret the sedimentation effect on fluvial inputs, marine and terrestrial vegetation changes. The research is a part of Expedition of Widya Nusantara 2016 which was conducted on 4 - 26 August 2016 using Baruna Jaya VIII research vessel. Thirteen surface sediment samples were analyzed by acetolyisis method and swirling. Pollen spectra illustrate the relationships between pollen distribution in the sampled marine sediments and their transport from the vegetation onshore. The pollen distribution that accumulated a lot in western part of Sumba island were linked to fluvial inputs and controlled by the distance from the coast and water depth. Correlation test between the distribution of pollen and water depth as well as grain size (mean and mud percentage) showed moderate correlation (r=0.465; r=0.374 and r=0.443, respectively). Although the average of vegetation diversity index is in low category (index of 1.07), the pollen distribution percentage in these marine surface sediment samples reflects the local vegetation from the nearby onshore of Sumba island. The most dominant pollen comes from Family Poaceae. This study demonstrates that pollen records from marine surface sediment in the Sumba Waters have the potential tool to reconstruct palaeovegetation on the adjacent continent for the past and future climate variability study at these area.
