Abstract

Mount Ungaran is one of the dormant volcanoes in Central Java. The condition of the unspoiled forest in the Mount Ungaran area is a good habitat for fauna, including birds. There are several hiking trails traversed by mountain climbers, one of them is the Promasan hiking trail. This study aims to determine the diversity of bird species and identify their conservation status on the Promasan hiking trail. Data were colected by Indices Ponctuels d'Abondance (IPA), Line Transect, and Point Count methods. Bird species diversity was determined by the Shanon index. Determination of bird conservation status based on the IUCN Red List, CITES Appendix, Government Regulation (PP No. 7 of 1999) and Ministry of Environment and Forestry Regulation (PERMENLHK RI No. 106, 2018). The results showed that there were 24 bird species belonging to 19 families. The diversity of bird species was classified as moderate (Shanon index = 2.59). There were two species including CITES Appendix II. Based on the IUCN Red List, there was one species in the Endangered (EN) category, 23 species in the Least Concern (LC) category. There was one species that is protected according to Government Regulation (PP No. 7 of 1999). The 3 species include as protected under the Ministry of Environment and Forestry Regulation (PERMENLHK RI No. P.106, 2018). Monitoring the presence of birds in this area must be carried out regularly.

Abstract

Fertilizer substitutes elements that have been used by plants. There are two available fertilizers, inorganic and organic fertilizers. Long-term use of inorganic fertilizers on a land negatively affects the crop and the soil fertility, hence, the organic one is a better choice. This study aims to determine the effect of liquid organic fertilizer of banana peels on the growth of red spinach and determine the best treatment for red spinach growth. This study used a Completely Randomized Design consisted of 2 factors (dosage of POC banana peel and length of fermentation time). Each has 4 levels, 3 replicates. The results of data analysis using ANOVA test show that the treatment of fermentation length and dosage of POC banana peel increase growth parameters of red spinach include plant height, leaf number, leaf area, fresh weight, and dry weight, while the interaction treatment of fermentation length and dosage of POC banana peel affects almost all growth parameters, except for the leaf area parameter that shows no interaction. DMRT (α 5%) test shows that the best combination treatment for plant height and fresh weight is a dosage of 8 ml POC of banana peel that have been fermented for 15 days, and the best treatment for leaf number and dry weight is a dosage of 8 ml POC of banana peel that have been fermented for 10 days.

Abstract

Mangrove forest is a unique natural ecosystem with high ecological value. The mangrove ecosystem is one of the areas with high productivity due to the presence of litter and litter decomposition occurs and produces detritus. This study aims to describe aquatic biota associated with the remaining stands of mangrove plants in the area of land conversion in Lino Tolonggano Village, South Banawa District, Donggala Regency, so that the surrounding community can be informed about the importance of the existence of mangrove forests. This type of research is descriptive quantitative research, with survey method with purposive sampling technique. The data obtained were analyzed using the association determination formula as well as additional posters that will be used as information material to the public regarding the existence of mangroves in the area of land conversion. The results obtained in this study indicate that the types of mangroves and associated aquatic biota are Sonneratia alba, Rhizophora mucronata and Rhizophora apiculata for the mangrove group and Nerita sp, Telescopium telescopium L, Uca sp and Periophthalmus modestus for the aquatic biota group. Data analysis showed that there were associations between plant species in the form of negative associations. This indicates that the aquatic biota found are not biota that use mangroves as a place to live.

Abstract

White oyster mushrooms (Pleurotus ostreatus) can be used as fillers sausages mix because the physical properties of chewy like meat and high fiber content. The main raw material of sausages is meat, so that rejected layer chicken meat can be used even though it has low quality of the meat and less liked by the consumer, however, as a food ingredient it still has potential to improve the quality. Therefore, to improve the quality and preferences of the consumer, it is necessary to innovate processed into sausages with the addition of a fiber source, namely white oyster mushroom flour. This study aims to examine the use of white oyster mushroom as a source of dietary fiber in sausage processing. The research materials used were white oyster mushrooms, rejected laying hens and spices. The experiment was designed using a completely randomized design (CRD) with 4 treatments and 3 replications, which included: without the addition of white oyster mushroom flour P0 (0%), the addition of oyster mushroom flour at the level of P1 (5%), P2 (10%), P3 ( 15%). Data were analyzed based on analysis of variance using Statistical Analysis System (SAS–Software). The results showed that the level of white oyster mushroom flour increased the organoleptic value of color, aroma and texture significantly (P<0.05). The addition of white oyster mushroom flour was also higly significant (P<0.01) in increasing the crude fiber content of sausages. It can be concluded that cooking loss was higher in line with the level of white oyster mushroom flour. But not on the value of water holding capacity. The higher the level of white oyster mushroom flour, the higher the crude fiber of the sausage. In general, the quality of sausages meets the Indonesian National Standard (SNI 3820 - 2015), interms of normal organoleptic value.

Abstract

City parks, apart from having an aesthetic function as a place for recreation, also have an ecological function with vegetation components to soften the microclimate. Vegetation analysis was carried out in six city parks in Mataram City to determine the vegetation structure. Microclimate factors of the park, namely light intensity, air temperature and humidity inside and outside the park during the day and observations of sound attenuation at night have been carried out. Climatic data is carried out to determine the park's ability to reduce heat and air temperature, increase air humidity and reduce noise and determine the park's environmental discomfort index. Of the six urban parks observed in the city of Mataram, namely the parks of Ampenan, Malomba, Udayana, Sangkareang, Mayura, and Selagalas, it is known that there are three groups of vegetation structures, namely trees-shrubs, shrubs-trees, and shrubs. Vegetation with various compositions of life forms in each city park only controls 40 to 60% of the land area of the park. Urban parks in Mataram City have a low level of ability to soften the microclimate, which is below 5%. In reducing heat and air temperature, and increasing air humidity. City parks are also known to have a low ability to reduce noise. The city parks of Ampenan, Udayana and Sangkareang have an environmental comfort level equivalent to the discomfort felt by more than 50% of the population, while the Malomba, Mayura, and Selagalas parks have a level of comfort equivalent to the discomfort felt by less than 50% of the population. The existence of urban park vegetation is only able to reduce the discomfort index of 7 to 9%.
