Abstract

Kotadjawa, located on the west coast of Lampung, directly faces the Indian Ocean. Lithified calcareous sedimentary beds are prevalently outcropped along this coastline. These beds likely belong to the Simpangaur Formation, which may be associated with the paleocoastal depositional environment and tectonic uplift of the Indian Ocean. Therefore, we investigated the paleontological record, focusing on foraminifera as potential indicators of the paleoenvironment. This study aimed to identify, record, and calculate the relative abundance of benthic foraminifera in the sedimentary beds of Kotadjawa, Lampung. The samples were prepared via chemical treatment of 10% H2O2 for 48 hours. Our results revealed a diversity of benthic foraminiferal fossils within the sedimentary rock. Notably, 11 benthic foraminifera genera were fossilized in the observed outcrop: Textularia (18.4%), Sigmoilopsis (16.5%), Rectobolivina (15.4%), Uvigerina (15.5%), Nodosaria (14.5%), Elphidium (11.5%), Lenticulina (7.7%), Hormosina (6.8%), Bolivina (6.8%), and Globobulimina (5.8%). These results suggested that the sedimentary beds exposed in our study area ranging from the foreshore to the deep ocean floor ecosystem. This suggests that a sediment mixing event, possibly triggered by a paleocatastrophic event, influenced the deposition of these beds. This study provides new insights into marine paleoenvironmental conditions and paleocatastrophic events along the west coast of Lampung, Sumatra.

Abstract

The Bogor Botanical Garden (BBG) is a pivotal center for plant research and conservation, boasting a diverse collection of over 12,000 individual plants spanning various species. However, among the plant collections at BBG, some of them have the potential to be invasive. Therefore, this study aimed to uncover the plant collections at BBG with invasive potential and analyze the distribution of one of the most dominant collections, Epipremnum pinnatum (L.) Engl. The method employed in this research involved a literature review to identify which plant collections have invasive potential and a vegetation analysis on the distribution of E. pinnatum within BBG. Additionally, ANOVA analysis and regression models were employed to explore the relationship between environmental factors and E. pinnatum abundance. Results revealed that BBG hosted 78 potentially invasive plant species, with E. pinnatum comprising 28 individuals. Spatial analysis indicates a clustered distribution of E. pinnatum, influenced by seed dispersal mechanisms, environmental factors, and biotic interactions. Correlation analysis links soil pH, soil moisture, and canopy cover to E. pinnatum distribution. Canopy cover demonstrates a significant positive correlation with E. pinnatum abundance, suggesting its importance in providing favorable microclimates for growth. Regression analysis further supports canopy cover as a predictor of E. pinnatum presence. However, while a strong statistical association was observed, causal relationships require further investigation. This study underscores the complexity of ecological dynamics in BBG and emphasizes the need for comprehensive research to define underlying mechanisms driving plant distributions and interactions.

Abstract

Bactrocera is a pest that is detrimental to citrus farming. Bactrocera attacks cause developmental disorders in citrus fruit, including changes in fruit color (black spots appear from Bactrocera infection) and premature rot. Bactrocera also has a symbiotic relationship with Liberibacter asiaticus which causes Citrus Vein Phloem Degeneration (CVPD) disease which attacks phloem tissue in citrus plants. Bactrocera pest control was carried out by combining plants that have the potential to be used as biocides, namely kitolod, papaya, and lemongrass plants. This combination was used to switch the habits of fruit farmers who previously used synthetic pesticides to control pests.   Natural biocides are expected to have the same effectiveness as synthetic pesticides, but leave no residue on cultivated plants. A combination biocide from the three plants was made using the maceration method to obtain an infusion from each plant. Before being tested on Citrus plantations, an assay was carried out using an olfactometer to determine the effectiveness of the biocides. The research revealed that the combination of these three plants has the potential to be used as a natural biocide without leaving residueand causing damage or other developmental disorders to citrus plants.

Abstract

Lumut hati talus merupakan komponen penting ekosistem hutan pegunungan, yang berperan penting dalam retensi air, daur hara, dan sebagai indikator kualitas lingkungan. Tumbuhan rendah ini termasuk dalam kelompok polifiletik atau memiliki nenek moyang yang berbeda, tetapi memiliki bentuk yang mirip dan dapat bertahan hidup di ekosistem darat. Tujuan penelitian ini adalah untuk memperbarui informasi tentang identifikasi, klasifikasi, dan distribusi lumut hati talus di lereng Gunung Ungaran sehingga dapat mengungkap wawasan berharga tentang keanekaragaman hayati tumbuhan, dinamika ekosistem, dan potensi aplikasinya di berbagai bidang. Metode pengambilan sampel menggunakan teknik purposive sampling, plot, dan identifikasi literatur taksonomi. Hasil sebaran lumut hati talus di ketiga stasiun tersebar luas dan ditemukan 4 famili dengan 6 spesies lumut hati talus kompleks, yaitu Marchantia polymorpha L., Marchantia emarginata Reinw., Blume et al., Marchantia treubii Schiffn., Wiesnerella denudata (Mitt.) Steph., Dumortiera hirsuta (SW.) Nees., dan Cyathodium smaragdinum Schiffn yang termasuk dalam kelas Marchantiopsida. Selain itu, ditemukan 3 famili dengan 3 spesies lumut hati talus sederhana, yaitu Riccia treubiana Steph yang termasuk dalam kelas Marchantiopsida; Metzgeria furcata (L.) Dumort; dan Aneura maxima Schiffn yang termasuk dalam kelas Jungermaniopsida.

Abstract

Spatholobus is a genus that belongs to the Fabaceae that is known to contain various bioactive compounds and distributed across Asia, including Indonesia. However, exploration of Spatholobus in Indonesia is still rare. Therefore, DNA barcoding is used to support the exploration and conservation of Spatholobus in Indonesia. However, there is no universal marker that can be used across all plant species. In addition, there are still few studies related to DNA barcoding within the genus Spatholobus. The purpose of this study was to evaluate the rbcL, matK, and intergenic spacer psbA-trnH regions in silico that can be used as DNA barcodes for the genus Spatholobus. This study began with a sequence search on the NCBI database including the rbcL, matK, and intergenic spacer psbA-trnH genes   in the genus Spatholobus and Phaseolus coccineus as the outgroup. Each sequence was then aligned with ClustalW. Then, a phylogenetic tree was constructed using the Maximum-Likelihood (ML) with 1000× bootstrap. As a result, the rbcL, matK, and psbA-trnH regions can be used as markers for DNA barcoding in the genus Spatholobus with different specifications. The rbcL and matK can be used to distinguish Spatholobus at the genus level, while the psbA-trnH can be used to distinguish Spatholobus at the species level.

Abstract

Carica (Vasconcellea pubescens A.DC.) is a mountain papaya species with limited distribution in Indonesia, found in the Dieng Plateau, Central Java. Carica is well utilized by the Dieng Plateau community based on its local knowledge system. The decline of local knowledge is increasingly worrying, necessitating documentation efforts through ethnobotanical studies. This study aimed to examine the appreciation of the local community of the Dieng Plateau towards Carica ethnobotany. This study was descriptive research employing both qualitative and quantitative approaches, with interview techniques. The study was conducted in three Dieng Plateau villages: Dieng, Sembungan, and Karangtengah villages. The 30 respondents were selected by purposive and snowball sampling. The research instruments included interview guides and questionnaires. Appreciation was analyzed descriptively with a quantitative approach using a Likert scale. The results showed an excellent appreciation for preserving Carica in the surrounding environment (97.3%), while there was a low appreciation for using Carica to treat certain diseases (38%). Based on age, the elderly category showed the best appreciation for Carica utilization. Appreciation as a practice of local knowledge in the management and utilization of Carica can contribute to the conservation of Carica in the Dieng Plateau.
