Characteristics and Productivity of Some Pigeon Breeds in Bangladesh (Aves: Columbidae)
Full text linkThis is our hurried responsibility to introduce those pigeon breeds that have economic value. In this case, very common and productive breeds but moderately unknown in history or confusing on their scientific identity need to be focused elaborately. A survey in the country, as well as experiences on these pigeons, inspired to write this valuable fundamental composition. Pet shops, markets, and lofts have sulli (moos-sulli), chuva chandan (chua chandan), bombai (sotobanca/Italian crested mondain), kokah (laugher), and parvin (Australian red) pigeons are carrying a remarkable productivity in the country. Prices of adult and squabs are reasonable to all sorts of people

River Monitoring: In View of the Physical Habitat of the River and the Presence of Macroinvertebrates
Full text linkMonitoring of river aims to determine the condition of water quality. One alternative effort that can be used to have description of water quality is by reviewing the condition of the river\u27s physical habitat. In this regard, the physical habitat condition will affect the presence of macroinvertebrates. The aims of this study was to determine the quality of river by observing the physical habitat of the river and the presence of macroinvertebrates. Data collection techniques are carried out spatially by dividing the river into several segments by taking into the state of the environment which include industry area, agriculture (rice field) area, housing area, pipe oil area and the springhead of the river. Based on the results of the study, it shown that the condition of river waters can be categorized in an unhealthy condition. This can be seen from the type of substrate cover, river bank stability and human activities in the river. It causes by eroding, agricultural activities, livestock, waste disposal, sand mining and garbage disposal. These conditions also affect the composition of macroinvertebrates found in this waters, which have a high level of tolerance in unhealthy physical habitat conditions such as Limnodrilus sp. and Aulodrilus s
Effect of Bamboo (Bambusa sp) Shoot Liquid Organic Fertilizer On Growth of Pre-Anthesis Cayenne Pepper (Capsicum frutescens L.) By Hydroponics
Full text linkAn environmentally friendly agricultural system with organic fertilizer is used to reduce the use of chemical fertilizers, thus producing healthy agricultural products for consumption. Liquid organic fertilizer from bamboo shoots is an alternative substitute for chemical fertilizers in the planting of cayenne pepper (Capsicum frustescens L.) hydroponically. This study aims to determine the effect of bamboo shoot liquid organic fertilizer on hydroponic cayenne pepper pre-antithesis growth. The study was conducted at the Biology Laboratory of UIN Raden Intan Lampung, using a Completely Randomized Design (CRD) with 6 treatments with 3 replications. The treatments included negative control (water), positive control (AB mix), P1 = 10%, P2 = 15%, P3 = 20%, P4 = 25% ml. The parameters include plant height, number of leaves, stem diameter, plant fresh weight. Data were analyzed using One Way Anova (SPSS 17.0), followed by LSD at the 5% level. The results show the effect of treatment on all parameters. Control positive (AB mix) gave the best results on all parameters, then successively treated P4, P3, P2, P1, K0 (negative control). Although not as good as using an AB mix solution, the administration of bamboo shoots POC with a concentration of 25% can support the growth of hydroponic cayenne pre-synthesis
Peanut Pods (Arachis hypogaea L.) In Ex-Mining Limestone Soil Enriched with Indigenous Bacteria
Full text linkPioneer plants are found in the former limestone mining area, and there are bacteria in their root systems. These bacteria can be used as biofertilizers. This study aims to find out the use of indigenous PGPR in ex-mining limestone land to be able to increase the yield of pea (Arachis hypogaea L.) var. Tuban. This research was an experimental study with 5 treatments applying indigenous PGPR at concentrations of 0%, 25%, 50%, 75%, and 100% and consist of 5 replications. Stages of research include planting peanuts (Arachis hypogaea L.) var. Tuban by adding indigenous PGPR with the same dose and source in an environment with sufficient sunlight. The parameters observed were biomass, pithy weight, empty pod weight, wet weight, dry weight, pH, and temperature of the planting medium for peanuts. In this study, the results showed that the concentration of PGPR 25% had a significant effect on the dry weight of peanuts and doesn’t had significant effect on biomass. Meanwhile, the provision of PGPR with different concentrations did not have a significant effect on the temperature and pH of the lime mining soil planting mediaPioneer plants are found in the former limestone mining area, and there are bacteria in their root systems.

Genetic Similarity of Commerson’s Anchovy across Segara Anakan Cilacap Assessed Using Randomly Amplified Polymorphic DNA (RAPD) Markers
Full text linkSegara Anakan areas can be divided into three different regions according to their salinity. Salinity differences suggested that Commerson’s anchovy population in that area can be divided into three subpopulations due to genetic differences. Genetic differences among subpopulation can be assessed through a population genetic study using random amplified polymorphic DNA. This study aims to evaluate the genetic variation and differences of Commerson\u27s anchovy (Stolephorus commersonnii) collected at three different water salinities in Segara Anakan estuary Cilacap Indonesia. Total genomic DNA was isolated using the Chelex method. Genetic diversity and differences were assessed using RAPD markers and were analyzed statistically using an analysis of molecular variance, as implemented in Arlequin software. The results showed that high genetic diversity was observed within the subpopulations. However, no significant genetic differences were observed among subpopulations which indicate genetic similarity. A high number of offspring are likely to cause high genetic variation within subpopulations. Adult and larvae migration is the cause of genetics similarity across Segara Anakan. Another impressive result is that water salinity did not affect the genetic characteristic of Commerson,s anchovy. Genetic similarity of Commerson’s anchovy indicates that Segara Anakan forms a single genetic conservation unit

Full text linkMacroinvertebrate diversity is one of the biologicals and ecological indicators that allow it to become a reference in determining water quality. This study aimed to inventory and study the diversity of macroinvertebrate species using the 1 x 1 m2 transect method along the Sundak Beach, Gunung Kidul, Yogyakarta. The research was conducted on Sunday, October 13th, 2019, with a quadratic transect method of 10 stations from the lowest low tide to the middle of the sea. The data obtained in this study was the result of macroinvertebrates species inventory in each sampling point and the number of individuals of each species. The data was then analyzed using the Shannon-Weiner diversity index (H\u27). The results showed 45 macroinvertebrate species with 2590 numbers of individuals were found on the Sundak Beach. The most common species were Gastropods with 16 species, while the most individual species were Ophiuroidea (730 species). The diversity index of 1.28351 indicates that the diversity of macroinvertebrates in Sundak Beach is categorized as medium diversity
