Abstrak-Keberadaan fosil ostrakoda pada Formasi Bentang dan Formasi Koleberes, tidak pernah muncul untuk dijadikan acuan karakteristik kedua satuan batuan tersebut. Ostrakoda memiliki tingkat adaptasi tinggi terhadap lingkungan, sehingga dapat digunakan untuk interpretasi lingkungan pengendapan. Berdasarkan bukti penelitian dan catatan peneliti terdahulu, terungkap bahwa daerah penelitian dipengaruhi oleh aktivitas vulkanik. Hal ini menyebabkan pengawetan fosil ostrakoda kurang baik, fosil ostrakoda ditemukan dalam bentuk karapas teraglutinasi, sehingga determinasi fosil ostrakoda hanya dapat dilakukan sampai tingkat genus. Sebanyak 13 genus dengan total 900 specimen ostrakoda yang berasal dari 10 family antara lain: Trachyleberididae, Xestoleberididae, Leptocytheridae, Thaerocytheridae, Cytherideidae, Cushmanideadidae, Bythocyprididae, Cytheromatidae, Philomedidae, dan Bythocytheridae, dapat diidentifikasi dari 13 contoh batuan. Indeks diversitas ostrakoda daerah penelitian tergolong diversitas rendah - sedang. Genus ostrakoda yang melimpah pada kala Miosen Tengah hingga Pliosen Awal yakni Lankacythere yang termasuk dalam kumpulan ostracoda autochthonous dan Keijella, yang merupakan ostrakoda penciri lingkungan laut dangkal, paparan kontinen <100m dengan karakteristik laut tropis.

AbstractRecent measuring stratigraphic observation in Cikandung River has revealed the Late Pliocene stratigraphic and tectonic event. Research area is located in easter Bogor Trough. Previously, it was stated controversially pertaining to the stratigraphic relationship between Kaliwangu and Citalang Formations. The outcrop-based remark has never been explained, slightly intuitive. Making strike and dip measurements and stratigraphic analysis using tape and compass traverse were done to unveil the role of Plio-Pleistocene tectonic regime in stratigraphic-filling of the basin. Strike azimuths recorded from several locations of Citalang and Kaliwangu Formations show angular geometry and both of those sedimentary facies within formations indicate the significant and rapid change in depositional process. But interestingly, the angular geometry is only founded in the southern part of study area. To the north, angular relationship becomes parallel. This geometrical distribution implies the strong influence of tectonic regime in Late Pliocene interval. The evidence from outcrops observation conclude the unconformity between Citalang and Kaliwangu Formations.

The Kutai Basin is one of the large basins in East Kalimantan which was formed during the Tertiary Period. The sedimentation process in this basin is strongly influenced by sea level changes. This study conducts quantitative analysis using the abundance of small foraminifera and palynomorphs in well “FN O-1” located in the northern part of offshore Kutai Basin. It applies the Planktonic-Benthic Ratio to determine the range of the bathymetric-related environments in the entire depth interval. The aims of this study are to interpret the sequence stratigraphy in the Kutai Basin using small foraminifera and palynomorphs associated with sea level changes. Three sequence stratigraphy phases are identified; TST (Transgressive System Tract), HST (Highstand System Tract), and FSST (Falling Stage System Tract), from the Late Miocene to Pleistocene in an inner to outer neritic environment. The results of the P/B ratio calculation show that wells with a depth of 1,230 feet to 12,180 feet are predominantly located in the inner neritic zone with a ratio percentage less than 20%. The highest abundance of small benthic foraminifera reaching 534 individuals was found at a depth of 1,650 feet within the TST phase. The most abundant planktonic foraminifera (452 individuals) was observed at a depth of 1,350 feet during the TST-HST transition. The FSST revealed the most abundance of mangrove palynomorphs with 100 fossil grains at 11,640 feet and 56 back-mangrove palynomorphs fossils were identified within the TST at 2,340 feet. This study concludes that the abundance of small foraminifera and palynomorphs suggests both marine and terrestrial influences on the basin.

The prevalence rate of stunting in Indonesia is considered high at 27.5% on a national scale and 25.1% for West Java province. Stunting is a chronic malnutrition problem characterized by short stature. Stunting may be hereditary, but consumption patterns play a role as a risk factor for stunting. Knowledge about proper consumption patterns is known to prevent stunting. This includes conducting educational activities about nutritious feeding patterns in families.Nutritional fulfillment counseling for pregnant women and toddlers has been conducted for the community in Babakan Village, Pangandaran. Participants who took part in this activity were members of the Dewi Manik Integrated Health Post (Pos Yandu). In addition to counseling, questionnaires were also distributed to assess the community's level of knowledge about nutrition in the family. A total of 64 participants aged 20 to 35 years completed the questionnaire. From the results of questionnaires given before and after the counseling, it was found that participants' knowledge about nutrition for pregnant women and toddlers was already quite good, but it has not been well applied as there is still a stunting rate of about 25% among toddlers from the survey subjects.Several efforts, such as providing more interactive and specific counseling materials about stunting and independent nutritional fulfillment, as well as more detailed and regular information about disease impacts, can be carried out for residents to help increase their awareness to independently prevent stunting.

ABSTRACTThis research was conducted to determine environmental changes in the study area based on the abundance of foraminifera fossils and the lithology of the emerging rocks. The research area is in Jatiluhur District, Purwakarta Regency, West Java Province. Rock samples taken during the Advanced Geological Mapping activity were then used as a composite log, divided into 15 rock samples representing any changes in lithological characteristics. The number of small foraminifera fossils found from the 15 samples was 120,912 individuals with 75,840 individual planktonic foraminifera fossils and 45,072 individual benthonic foraminifera fossils. The abundance of small foraminifera fossils varies in number in each sample and the number is more abundant in the younger layers than in the older layers. The P / B ratio analysis was performed using a comparison calculation between planktonic and benthonic foraminifera. From the P / B ratio analysis, it was found that four bathymetric zones had occurred in the study area. From the results of the P / B ratio analysis and associated with rock lithology, it can be concluded that the environment of the study area is in a shallow sea where there have been several times of local deepening and silting of the water column. The analysis of environmental changes is strengthened by drawing the age which is determined based on the appearance of the fossil index in the layers. Referring to Bolli & Saunders (1985) and Boudagherfadel & Banner (1999), the results of this analysis indicate that the study area was deposited at an age not older than the Middle Miocene.Keywords: Foraminifera, Abundance, Environment, Lithology, Middle MioceneABSTRAKPenelitian ini dilakukan untuk mengetahui perubahan lingkungan pada daerah penelitian berdasarkan kelimpahan fosil foraminifera dan litologi batuan yang muncul. Daerah penelitian berada pada Kecamatan Jatiluhur, Kabupaten Purwakarta, Provinsi Jawa Barat. Sampel berupa batuan yang diambil ketika kegiatan Pemetaan Geologi Lanjut yang kemudian dijadikan sebuat composite log terbagi menjadi 15 perconto batuan mewakili setiap perubahan karakteristik litologi. Jumlah fosil foraminifera kecil yang ditemukan dari 15 sampel tersebut adalah 120.912 individu dengan fosil foraminifera planktonik 75.840 individu dan foraminifera bentonik 45.072 individu. Kelimpahan fosil foraminifera kecil bervariasi jumlahnya pada masing-masing sampel dan jumlah tersebut lebih melimpah pada lapisan yang lebih muda dibandingkan dengan lapisan yang lebih tua. Analisis P/B ratio dilakukan menggunakan perhitungan perbandingan antara foraminifera planktonik dan bentonik. Dari hasil analisis P/B ratio didapatkan empat zona batimetri pernah terjadi pada daerah penelitian. Dari hasil analisis P/B ratio dan dikaitkan dengan litologi batuan, dapat ditarik kesimpulan bahwa lingkungan dari daerah penelitian berada pada laut dangkal dimana terjadi beberapa kali pendalaman serta pendangkalan kolom air secara setempat. Analisis perubahan lingkungan diperkuat dengan penarikan umur yang ditentukan berdasarkan kemunculan indeks fosil pada lapisan. Mengacu pada Bolli & Saunders (1985) dan Boudagherfadel & Banner (1999), hasil analisis tersebut menunjukkan bahwa daerah penelitian diendapkan pada umur tidak lebih tua dari Miosen Tengah.Kata Kunci : Foraminifera, Kelimpahan, Lingkungan, Litologi batuan, Miosen Tengah.
