Foraminifera telah banyak digunakan sebagai indikator kualitas perairan sekitar terumbu karang di Indonesia berdasarkan perbandingan kelompok foraminifera bentonik tertentu. Studi tersebut diterapkan di sekitar Pulau Tegal, Teluk Lampung yang merupakan salah satu destinasi wisata yang secara tidak langsung memberikan pengaruh terhadap ekosistem terumbu karang. Penelitian ini bertujuan untuk mengetahui struktur komunitas foraminifera bentonik kaitannya dengan kondisi perairan terumbu karang Pulau Tegal, Teluk Lampung. Penelitian ini dilakukan pada 16 stasiun penelitian di Pulau Tegal yang mewakili semua sisi pulau dengan variasi kedalaman dari 0 meter hingga 28 meter. Hasil dari penelitian ini ditemukan 6.918 spesimen foraminifera bentonik dengan keanekaragaman yang tergolong rendah. Genera Amphistegina dan Elphidium ditemukan sangat melimpah pada hampir seluruh stasiun. Nilai Indeks FORAM (FI) diatas 4 ditemukan pada 11 stasiun penelitian yang mengindikasikan bahwa sebagian besar perairan Pulau Tegal berada dalam kondisi yang sangat baik dan kondusif untuk pertumbuhan serta pemulihan terumbu karang. Hasil ini sejalan dengan melimpahnya kehadiran kelompok foraminifera yang berasosiasi dengan terumbu karang pada perairan Pulau Tegal.Kata Kunci: Bioindikator, Pulau Tegal, Indeks FORAM, Terumbu Karang, Komunitas.Foraminifera has been widely used as an indicator of the quality of the waters around coral reefs in Indonesia based on the comparison of certain groups of benthonic foraminifera. The study was implemented around Tegal Island, Lampung Bay, which is one of the tourist destinations that influence the coral reef ecosystem. This study aims to determine the structure of bentonic foraminifera communities related to the condition of the coral reef waters of Tegal Island, Lampung Bay. This research was conducted at 16 research stations in Tegal Island representing all sides of the island with variations in depth from 0 m to 28 m water depth. The results of this study found 6.918 specimens of bentonic foraminifera with relatively low diversity. The genera Amphistegina and Elphidium were found to be very abundant in almost all stations. The FORAM Index (FI) above 4 was found in 11 research stations which indicated that most of the waters of Tegal Island were in very good conditions and conducive to the growth and recovery of coral reefs. This result is in line with the abundance of the presence of foraminifera groups associated with coral reefs in the waters of Tegal Island.

Emisi CO2 Kendaraan Bermotor Periode Kebijakan Pembatasan Sosial Berskala Besar (Studi Kasus: Ruas Jalan Di Jakarta Pusat). Jakarta Pusat sebagai jantung kota DKI Jakarta memiliki arus pergerakan orang dan barang yang tinggi terutama dalam penggunaan kendaraan bermotor. Pembakaran bahan bakar kendaraan bermotor menyebabkan semakin meningkatnya akumulasi CO2 di atmosfer. Pada awal tahun 2020 berbagai negara di dunia termasuk Indonesia dan Jakarta mengalami pandemi Covid19 yang mendorong pemerintah menerapkan pemberlakuan kebijakan pembatasan sosial berskala besar (PSBB) untuk menekan kasus penyebaran Covid19. Adanya PSBB mengakibatkan dampak terhadap berbagai aspek kehidupan masyarakat termasuk keterbatasan aktivitas dan mobilitas masyarakat menggunakan kendaraan bermotor. Tujuan penelitian ini adalah untuk mengetahui besaran emisi CO2 saat periode kebijakan PSBB di tiga ruas jalan Jakarta Pusat. Metode penelitian ini dilakukan secara deskriptif kuantitatif meliputi besaran konsumsi BBM masyarakat menggunakan kuesioner, data lalu lintas harian rata-rata (LHR) kendaraan bermotor bersumber dari Dinas Perhubungan DKI Jakarta dan besaran emisi CO2 menggunakan perangkat lunak Mobilev 3.0. Hasil penelitian ini didapatkan besaran rata-rata konsumsi BBM tiap kendaraan saat PSBB yaitu untuk sepeda motor sebesar 4,01 liter/unit kendaraan dan mobil sebesar 20,6 liter/unit kendaraan. Total LHR kendaraan bermotor keseluruhan pada tiga ruas jalan sebesar 159.621 kendaraan (PSBB Transisi) dan sebanyak 132.623 kendaraan (PSBB Total). Total besaran emisi CO2 keseluruhan dari tiga ruas jalan saat PSBB transisi sebesar 68.863 ton/tahun dan saat PSBB total emisi CO2 sebesar 52.287 ton/tahun. Urutan emisi CO2 tertinggi berada di Jalan MH. Thamrin, kemudian Jalan Abdul Muis dan emisi terendah berada di Jalan Prajurit KKO Usman Harun. Berdasarkan penelitian ini, secara keseluruhan terjadi penurunan emisi CO2 pada tiga ruas jalan sebesar 24% antara kondisi PSBB Transisi dan PSBB Total. Penurunan emisi CO2 terjadi karena adanya keterbatasan mobilitas masyarakat menggunakan kendaraan bermotor dan perubahan konsumsi BBM selama periode kebijakan PSBB.

The red chick barb [Puntius orphoides (Valenciennes 1842)] is a member of Cyprinidae with high economic value. However, this species is still uncultured. The high market demand is fulfilled by direct collection from their natural habitat. In order to avoid overexploitation, domestication effort is needed. The success of this effort needs some biological information e.g. reproductive characters. This research aims to know some reproductive characters of red cheek barb collected at Klawing River Purbalingga Central Java. A survey method was used with performing simple random sampling technique. The measured parameters were gonad maturity, fecundity, and gonad somatic indices (GSI) related to total length. The fish were collected monthly from June until November 2009. Data analysis includes length distribution, and correlation among gonad maturity, fecundity, and gonad somatic indices with body length. The result showed that red cheek barb from Klawing River has variable body length, most of the female individuals (34.37%) had body length ranges from 14.3-16.2 cm, whereas the majority of the male individuals (44.95%) had length distribution from 12.1-14.6 cm. The variation on gonad maturity was observed during the research both on female and male individuals. However, most of the populations were on the highest level of gonad maturity (level IV) only in September and October. A positive correlation between gonad maturity and body length was observed on the male individuals (r=0.0424) as well as on the female individuals (r=0.4339). The fecundity was ranges from 4.097 up to 32.794 eggs. A positive correlation was also observed between fecundity and body length (r=0.6403). A monthly GSI variation was found both on the female and the male individuals with the highest peak of GSI was observed in September and October. A positive correlation between GSI and body length was found on female individuals (r=7.07 x 10-3) as well as on male individuals (r=0.376).

Pseudodiaptomus species are one of the copepods species as a superior live feed to date due to their nutrition and digestive enzyme contents. Some of them have been used as natural for rearing marine fish larvae. The purposes of this study were to compare the nutritional and protease activity between two species of Pseudodiaptomus originated from Indonesian waters, and to determine more superior species to cultivate. Two different feeds i.e. Thalassiosira sp. and milk powder were used to grow the Pseudodiaptomus species. Analysis of amino acids (AAs) and fatty acids (FAs) profiles were carried out for both the Pseudodiaptomus species samples and the feeds, while the protease activity assay was carried out only for the Pseudodiaptomus species samples. Results indicated that the nutritional and protease activity profiles of Pseudodiaptomus were affected by the types of feed. Pseudodiaptomus code P61 was more superior to Pseudodiaptomus code P71. This code P61 species contained a wide variety of essential fatty acids and exhibited stabile protease activity under the different feeding treatments. However, P61 contained a lower total AA content than P71. Both of them could be cultivated because they were complementary in nutrients to each other.

Phytoplankton is an autotrophic organism that produce its own food through the process of photosynthesis with the help of sunlight which forms the basis of water productivity to be utilized for trophic organisms above. In freshwater, river plankton are categorized as potamoplankton. Rivers are a dominant freshwater ecosystem and have a more stable morphology than other freshwaters. Changes in land function is triggered by an increase in human population, an increase in the number of residential areas and industrial activities that discharge untreated waste into the river. Because of the importance of phytoplankton for life, it is necessary to conduct research on the Comparison of Phytoplankton Composition and Abundance Based on Different Land Uses in the Cisadane River, Tangerang Regency. In this study, sampling was carried out using a purposive sampling method by measuring parameters such as pH, temperature, and water transparency. Identification of phytoplankton composition and abundance was carried out using the Sedgwick Rafter Counting Cell (SRCC) using the sweep method. The results of this study obtained 23 phytoplankton genera from 6 classes consisting of: Bacillaryophyceae, Cyanophyceae, Chlorophyceae, Conjugatophyceae, Trebouxiophyceae, and Zygnematophyceae. Phytoplankton abundance was 185-490 Ind/L with the highest abundance in both areas are Bacillaryopiceae and Navicula. The diversity index was 1.307-2.124 and the dominance index was 0.201-0.461. Water quality parameters that affect the composition and abundance of phytoplankton are water-transparency, pH, and water temperature.

Agroforestry-integrated community forests foster greater plant diversity compared to conventional agriculture, potentially offering significant ecological and societal benefits. However, the specific contribution of diverse floor vegetation within these forests to carbon cycling remains understudied. This study addresses this knowledge gap by comprehensively analyzing the floristic composition and carbon storage potential of floor vegetation in tropical community forests. Using a stratified random sampling design with quadrats to ensure representative data collection across various locations in Ciamis Regency, West Java, Indonesia, we identified 296 plant species belonging to 89 families. Our analysis revealed that the understory vegetation exhibits moderate species diversity and stores carbon ranging from 0.107 to 0.238 Mg C ha⁻¹, with an average sequestration potential of 0.730 Mg C ha⁻¹. These findings suggest that community forests harbor diverse floor vegetation communities with significant carbon storage and sequestration potential, providing valuable insights for environmentally sustainable community forest management and contributing to broader efforts towards climate change mitigation.
