Abstract

The development of wild caves into show caves is required an installation of electric lights along the cave passages for illumination and decoration purposes for tourist attraction. The presence of artificial lights can stimulate the growth of photosynthetic organisms such as lampenflora and alter the typical cave ecosystem. The study was aimed to detect the effect of lampenflora on cave-dwelling arthropods community. Four caves were sampled during the study, 2 caves are show caves with the existence of lampenflora and 2 others are wild caves without lampenflora. Arthropods sampling were conducted by hand collecting, pitfall trap, bait trap and berlese extractor. Lampenflora comprises of algae (Phycophyta), moss (Bryophyta) and fern (Pteridophyta) grow mostly around white light lamps. Richness, diversity, and evenness indices of Arthropods are higher in caves with the existence of lampenflora compared to caves without lampeflora. This study clearly shows that the presence of lampenflora can increase Arthropods diversity and suppress dominancy of common Arthropods species in caves, also increasing the relative abundance of predators. This condition will shift the ecosystem equilibrium and lead to cave ecosystem destruction. The results of this study should be a scientific consideration for show cave development and management. Lampenfloras have to be removed from all caves and preventive efforts should be taken to minimize their growth.

Abstract

Rainfall is a natural phenomenon that needs to be studied more deeply and interesting to be analyzed. It involves numbers of human activities such as aviation, agriculture, fisheries, and also disaster risk reduction. Moreover, the characteristics of rainfall data follows seasonality, fluctuation, not normally distributed and it makes traditional time series challenging to use. Therefore, neurocomputing model can be used as an alternative to extraction information from rainfall data and give high performance also accuracy. In this paper, we give short preview about SST Anomalies in Manado, Northern Sulawesi and at the same time comparing the performance of rainfall forecasting by using three types of neurocomputing methods such as Generalized Regression Neural Network (GRNN), Feed forward Neural Network (FFNN), and Localized Multi Kernel Support Vector Regression (LMKSVR). In a nutshell, all of neurocomputing methods give highly accurate forecasting as well as reach low MAPE FFNN 1.65%, GRNN 2.65% and LMKSVR 0.28%, respectively.

Abstract

The Covid-19 pandemic that has been attacked almost all countries in the world since 2020 has changed the lifestyle and habits of peoples globally. Since this outbreak until now, peoples in all countries including in Indonesia must implement the health protocols to reduce the rate of virus transmission. One of them is by maintaining hand hygiene by washing hands using soap or hand sanitizer (HS).  HS is used as an alternative in conditions which is difficult to washing hand. But, rural communities, especially in Tangguh Village in Kampung Pasir Honje, Sukawening, Ciwidey, Bandung Regency, are currently unable to use it due to limited access and economy. Training of making HS for the community can be a solution in overcoming this problem. Thie aims of this activity to provide skills to the people of Tangguh Village to make hand sanitizers made from alcohol and non alcohol. Method: conducted by lectures and do questions and answers about HS and then direct practice of making HS. Result: All participants can make hand sanitizers well. There are 2 types of HS that have been successfully made by the community, namely HS containing alcohol and HS free of alcohol. The alcohol content in the first type is around 60-70%, while the alcohol-free HS is made from betel leaf extract because it contains antibacterial compounds. The results of the evaluation show that 50% of the participants stated that they were very satisfied with the implementation of this activity and about 92% stated that this activity was very beneficial for them.

Abstract

Gua memiliki potensi besar sebagai tempat penularan Covid-19. Aktivitas penelusuran gua di masa pandemi berpotensi meningkatkan dan memperluas penyebaran Covid-19. Artikel ini bertujuan untuk memberikan informasi mengenai potensi bahaya aktivitas penelusuran gua di masa pandemi Covid-19 dan upaya-upaya yang dapat dilakukan untuk mencegahnya. Data diperoleh melalui metode Systematic Literature Review (SLR). Lingkungan gua memiliki karakter tertutup, tidak terdapat sinar matahari, minim ventilasi dan sirkulasi udara, suhu stabil dan kelembapan tinggi sehingga sangat ideal untuk terjadinya proses penularan Covid-19 antar manusia. Selain itu, gua juga menjadi habitat bagi kelelawar (Chiroptera) yang ternyata memiliki kemungkinan  tertular Covid-19 dari manusia. Rute transmisi virus dari manusia ke kelelawar dan ditularkan kembali ke manusia dikhawatirkan terjadi. Pencegahan penyebaran Covid-19 di lingkungan gua dapat dilakukan di antaranya adalah dengan cara menunda kunjungan ke gua apabila kepentingan tidak mendesak, menggunakan peralatan SOP penelusuran gua, menerapkan protokol kesehatan dengan ketat, pembatasan jumlah penelusur dan durasi eksplorasi, tidak kontak langsung dengan kelelawar, dan menghindari lorong-lorong gua yang menjadi habitat kelelawar.

Abstract

Cave crickets are considered as a keystone species that can be used as a cave ecosystem bioindicator. Developing caves as tourism has considerable potential to disturb cave cricket populations. This study aimed to investigate cave cricket population structure and their habitat preference in Sanghyang Kenit cave one year after it developed into a show cave. Data were collected through standardized visual searching in three cave zones: entrance, twilight, and dark. Besides cave crickets, other macroarthropods discovered in each zone were also recorded. Abiotic parameters of habitat comprised air and soil temperatures, RH, soil moisture, soil pH, and light intensity were measured. Data were analyzed to show cave crickets abundance, density, sex ratio, and age structure. Statistical analysis comprising Kruskal Wallis, non-metric multidimensional scaling, and correlation tests were performed. The cave cricket population in Sanghyang Kenit belonged to a single species, Rhaphidophora sp. The population was around 78-108 individuals and distributed in all cave zones. The abundance and density in twilight and dark zones were significantly higher than in the entrance. The number of males outperformed females with a 2.16 ratio. Besides, the population was dominated by the sub-adult class. Environmental parameters of twilight and dark zones tended to be similar to one another compared to the entrance. Cave crickets preferred habitats with dark, humid, and acidic soil pH. Heteropoda sp. and Catagaeus sp. were considered potential predators. This study implies the importance of protecting cave crickets in Sanghyang Kenit.

Abstract

AbstrakAraknida merupakan kelompok fauna yang umum dijumpai di gua dan berperan penting menjaga keseimbangan ekosistem gua. Kelompok fauna ini dapat ditemukan di seluruh zona gua baik terang, remang, maupun gelap. Penelitian ini bertujuan untuk mengetahui perbedaan keanekaragaman dan kelimpahan araknida berdasarkan zonasi gua. Pengambilan data dilakukan di 3 gua yang terletak di kawasan Karst Tasikmalaya, yaitu Gua Sarongge, Liang Boeh, dan Liang Seungit. Pencuplikan araknida dilakukan dengan teknik hand collecting, sedangkan penghitungan individu dengan direct counting. Selain itu, dilakukan pengukuran parameter abiotik yang terdiri dari suhu udara, suhu tanah, kelembapan udara, kelembapan tanah, dan intensitas cahaya. Data dianalisis dengan uji indeks similaritas Jaccard, one-way ANOVA, Kruskal Wallis, dan Canonical correlation analysis. Terdapat 311 individu araknida tergolong dalam 3 ordo dan 7 morfospesies yang berhasil dikoleksi. Mayoritas araknida tergolong kategori adaptasi troglofil. Terdapat kemiripan komposisi spesies yang tinggi antara zona remang dan gelap (indeks similaritas 0,833) dibandingkan kemiripan keduanya dengan zona terang (0,571 dan 0,429). Kelimpahan individu araknida antar zona tidak berbeda secara signifikan. Mayoritas spesies memiliki preferensi habitat dengan kondisi intensitas cahaya rendah dan kelembapan tinggi.AbstractArachnid is one of the cave-adapted fauna with diverse cave representatives and plays a vital role in maintaining ecosystem balance. This group is widely distributed in all cave zonation, namely entrance, twilight, and dark zones. This study aimed to reveal the difference in diversity and abundance of arachnids in different caves zonation. The study was carried out in three caves situated in Tasikmalaya karst region, namely Sarongge, Liang Boeh, and Seungit. Arachnids were sampled through hand collecting, while abundance was estimated through direct counting. Air and soil temperatures, relative humidity, soil moisture, and light intensity were also measured. Data were analysed through Jaccard’s similarity index, one-way ANOVA, Kruskal Wallis, and CCA. In total, 311 individuals belonged to 3 orders and 7 morphospecies were identified. Most observed morphospecies were categorized as troglophiles. There was a great degree of similarity in species composition between twilight and dark zones (similarity 0.833) compared to entrance zone (0.571 and 0.429, respectively). Meanwhile, abundance was relatively similar. Most species prefer habitats with low light intensity but high humidity.

Abstract

The monoterpene compound has been reported to have antiviral activities . This study aimed to test the monoterpene compound in Melaleuca leucadendra to inhibit the SARS-CoV-2 virus. The monoterpenes tested were α-Pinene, β-Pinene, Linalool, α-Terpineol, and Terpinene-4-Ol. The method used was computational through pharmacophore analysis. The indicator for the quality of the compound was the fit score. A fit score of more than 50% indicates a good-quality compound, while a fit score of less than that indicates a  poor-quality compound. Based on the analysis results, the monoterpene compound in Melaleuca leucadendra can potentially inhibit the SARS-CoV-2 virus directly through the inhibition of 3C-like protease. The linalool showed a fit score of 55% with interactions of hydrophobic, electrostatic, and hydrogen bonds. All the compounds did not inhibit the metabolic process and were safe, possibly having no side effects based on ADMET analysis.

Abstract

Gunungsewu is one of the largest and well-known karstareas in Indonesia. This karst area has an interesting endokarst(cave) ecosystem. One type of faunas that is common in caveecosystem is whip spiders (Order: Amblypygi). This fauna plays animportant role in maintaining cave ecosystem balance because theyact as top predator. Gebyok is a cave in Gunungsewu that isinhabited by whip spiders. This study aimed to monitor thepopulation dynamic of whip spiders in Gebyok. Data collection wascarried out by direct observation as long as 10 years starting from2010 until 2020. The annual population of whip spiders in Gebyokwas relatively stable (around 30-40 individuals). Meanwhile, thepopulation fluctuated significantly every month. The largestaverage of individuals record occurred in July (5) and the smallestwas in January (0.66). The population dynamic of whip spiders inGebyok was strongly affected by underground river activity.
