Abstract

The Kariangau Industrial Zone extends industry from Balikpapan city in the Central Balikpapan to the coast in Western Balikpapan, forming a part of Balikpapan Bay. Our study aimed to estimate the diversity, species composition, and the abundance distribution of birds at the industrial zone of Balikpapan City. Our study contained six replicates each of boat transects on four rivers, the Somber, Getah, Paka Dua, and Wain rivers during the months of May and June 2017. We calculated the Margalef diversity and Bray–Curtis similarity indices to estimate diversity and species composition, whereas bird abundance distributions were analyzed using Paleontological Statistics (PAST) version 3.12. The Getah river had the highest diversity index (4.846), followed by the Somber (3.988), Wain (3.510), and Paka Dua (3.050) rivers. The Bray–Curtis index revealed high similarity in species composition between the Wain and Paka Dua. Our rarefaction analysis showed that the Wain and Paka Dua rivers were well sampled and had lower species richness, with low differences between the observed and expected species richness, than the Somber and Getah rivers. Fisher Log Series Model also showed abundance distribution being highest at Getah (11.170), and lowest at the Paka Dua Rivers (5.221). This observation may be due to heightened industrial activities and boat traffic on each river. Our study provides a useful baseline for future research on the bird assemblages on Balikpapan Bay.

Abstract

Balikpapan Bay is one of the wetlands providing potential foraging habitat for waterbirds in Indonesia. Potential habitat loss due to oil industry expansion, recent waterbird occurrence, and co-occurrence of two closely related species with similar foraging characteristics led to habitat selection. Habitat selection could be affected by food as an intrinsic factor and extrinsic factor, for example, accessibility to the physical and biological components of the habitat. This study aimed to measure the foraging habitat selection, identify significant habitat quality parameters for the habitat selection and predict the foraging habitat selection model. We used one-zero sampling for collecting foraging habitat selection data, corer sampling for prey data, and collecting the abiotic environment, and Generalized Linear Modelling (GLM) to build the model. We identified four species as the migrant Little Egret (Egretta garzetta), Great Egret (Ardea alba), Purple Heron (Ardea purpurea), and Lesser Adjutant (Leptoptilos javanicus). All species, except Purple Heron, selected foraging habitats. A simple mathematic model of foraging habitat selection was significantly affected by two factors: water depth and patch area. A large patch area may provide primary prey abundance for waterbirds, while a low water depth level may give easy access to the prey.

Abstract

The Fairy Pitta Pitta nympha is an uncommon migrant known to visit Borneo during the non-breeding season. However, within Indonesia there are no published records of this species outside Kalimantan (Indonesian Borneo). We encountered single immature Fairy Pittas at Anambas island (Riau islands, Sumatra) in October 2019, and in Bogor and Jakarta (Java) in November 2019, suggesting an influx of young birds migrating beyond their normal wintering grounds.

Abstract

Pseudagrion pruinosum (Burmeister) is a common damselfly that is widely distributed in Southeast Asia. However, information related to the oviposition behavior and habitat is still limited. This study was aimed to determine the behavior of P. pruinosum when laying eggs and characterized the oviposition habitat. This research used focal sampling method to observe oviposition behavior and measure habitat parameters on egg-laying location. Results showed, there was mate guarding when P. pruinosum females lay eggs. The male forms a tandem formation (contact mate guarding), then released the female and keep a guarding behavior around the female (noncontact mate guarding). Eggs were placed by the female on plant tissue with the technique of positioning the body to remain on the surface and then submerged. There is no tendency of P. pruinosum behavior towards one type or technique. Based on the results of principal component analysis, 75.8% of habitat components can be described for egg-laying habitat. Air temperature, pH, light intensity, and heterogeneity of vegetation positively correlated with the occurrence of egg-laying while TDS, humidity, water depth, and water temperature were negatively correlated. The results of this study concluded that the characteristics of egg-laying techniques included, i.e contact and noncontact mate guarding by the males and females putting eggs on the surface then submerged into water.

Abstract

This study aimed to examine the molasses addition as a glucose source in the process of elephant grass silage. A completely randomized design consisting of five treatments and five replications was used in this study. The treatments were P1: elephant grass (EG) as control, P2: EG + 2.5% molasses, P3: EG + 5% molasses, P4: EG + 7.5% molasses and P5: EG + 10% molasses based on dry matter. All the treatments were ensiled for 30 days. The parameters included physical quality were aroma, mold growth, texture while the chemical quality parameters were pH, dry matter, dry matter loss, and fleigh value. The data were analyzed for variance and if there were differences between treatments, the Duncan's test was conducted at the 5% level. The results showed that 10% molasses addition had a significant effect (p<0.05) on the physical and chemical qualities of elephant grass silage. The elephant grass silage had a distinctive fermented aroma, no fungi, smooth texture, no clump, and brownish-green color following the molasses color. The pH of elephant grass silage was 3.37-4.52, the silage dry matter was around 27.5%-32.5%, the dry matter loss was around 2.76%-6.73%, while the fleigh value was around 79.2-135. It could be concluded that molasses could be used as a stimulant additive to ensilage elephant grass. Key words: dry matter loss, elephant grass, fungal growth, fleigh value, molasses, pH, silage

Abstract

Indonesia's coastal region is known for its richness and diverse natural resources. However, the region is experiencing a transformation from mangrove ecosystems to the traditional pond cultures. This was happening in West Sulawesi that could damage the ecosystem in the long term, especially for the bird community. This study aims to inventory bird species in the bird community on the coast of Tandung Village, Tinambung District, Polewali Mandar Regency, West Sulawesi Province. In addition, we also study the bird community structure, find out the correlation among the bird communities, and the environmental condition during the inventory. In this study, we used a fixed-radius point count method to record birds. Field guide titled Burung-burung Pulau Paparan Sunda dan Wallacea di Kepulauan Indonesia was used to identify the species of observed birds. The results showed that of the 27 species recorded, there are 5 species with a high relative abundance, such as Egretta garzetta, Himantopus leucocephalus, Actitis hypoleucos, Ardeola speciosa, and Calidris ruficollis. Only H. leucocephalus is identified as a protected bird by the Indonesian government, while Calidris ruficollis is protected internationally as its conservational status (Near Threatened). The diversity index is moderate level, but it is decreasing day by day of observation, followed by the dominance index, evenness, and species richness. A high correlation between the two bird communities with two adjacent days of observation indicates similarity composition of community structure with different temporal scales and similar spatial scales. The map of environmental conditions shows changing weather in the period of observation sequentially from bright sky to cloudy and heavy rain and back to the normal bright sky at the last period of observation. The response of the bird community to the condition was by flying away when the weather is cloudy and rainy so that may decrease the diversity.

Abstract

Alzheimer's Disease (AD) currently has no definitive medication. The trend has shifted towards utilizing bioactive compounds found in fermented foods as potential medications for AD. Several studies have identified AD medication and prevention compounds in certain types of fermented foods. However, the potential of shrimp paste, a popular Indonesian food rich in bioactive compounds, in preventing and curing AD has not been studied yet. Therefore, this research aims to identify potential volatile compounds in shrimp paste that could be candidates for AD medication. The first method involves a systematic review to collect volatile compound data from Indonesian shrimp paste. Subsequently, an in silico approach is used to screen potential compounds through three steps: analyzing biological activity, predicting target proteins, and analyzing toxicity. The results reveal 68 volatile compounds, 9 potential compounds, and only 6 compounds with a probability value greater than 0.3. These compounds are then tested in silico for correlation with AD based on the way2drug website. The analysis identifies 30 potential target proteins for AD medication. However, the pirazina compound is found to have carcinogenic activity, highlighting the need for further in vitro and in vivo analyses to identify potentially volatile compounds that could be candidates for AD medication.

Abstract

An indicator of a good village is having a clean environment and local residents free from all diseases. In addition, local residents have commodities to be more independent in terms of economic development. This is of course not only the responsibility of village officials, but requires the support and cooperation of local residents as well. Therefore it is necessary to make use of the village environment which can realize the indicators previously mentioned. The first step that can be taken is to start with your own yard. Because based on observations, the service team found that in the partner village, namely Balombong village, it had not been used properly and there were empty lands in the residents' yards. So that the purpose of implementing this service is to provide education for residents to be able to take advantage of the yard by planting fruit in pots. This can make the environment more beautiful, healthy and the results can help the local economy

Abstract

Getah kemenyan dengan genus Boswellia telah lama digunakan secara tradisional pada beberapa penyakit. Kandungan Boswellia salah satunya adalah asam boswellic. Asam boswellic memiliki aktivitas neuroprotektif dan antiinflamasi. Beberapa jenis asam boswellic yang paling banyak diteliti mengenai efek farmakologi adalah asam 11-keto-β-boswelik (KBA), asam asetil-11-keto-β-boswellik (AKBA), dan β-boswelik (βBA). βBA diteliti memiliki efektivitas permeabel terhadap Blood Brain Barrier (BBB) dibandingkan jenis asam boswellic lainnya. Oleh karena itu, βBA memiliki potensi yang lebih besar dalam pengaruhnya pada otak terutama hippocampus. Review ini bertujuan untuk memberikan informasi lengkap dan membahas mengenai pengaruh boswellic acid pada performa hippocampus di otak terutama efek pada fungsi kognitif, efek farmakologis pada studi in vivo dan invitro, serta mekanisme molekuler sehingga diharapkan dapat menjadi pengetahuan sebagai acuan dalam melakukan penelitian lanjutan. Pemberian asam boswellic memberikan efek neuroprotektif dan antiinflamasi pada hippocampus sehingga dapat bekerja menghambat apoptosis sel di hippocampus, meningkatkan viabilitas sel saraf, dan meningkatkan kemampuan learning dan memori serta kognitif melalui anti-infalamasi. Beberapa mekanisme molekuler asam boswellic yang dapat mempengaruhi performa hippocampus adalah 5-Lipoxygenase (5-LOX), peningkatan Nuclear factor erythroid 2–related factor 2 (Nrf2), penekanan aktifitas acetylcholinesterase (AChE), dan pengaturan Ca (2+/-) dan protein kinase teraktivasi mitogen (MAPK). Akan tetapi, penelitian mengenai pengaruh boswellic acid pada performa hippocampus masih sangat terbatas dan perlu dilakukan penelitian lebih lanjut terutama pada manusia.
