Abstract

As Black Soldier Fly farming has become an emerging trend in Indonesia there is a new opportunity to take advantage from the waste generated from the activity. One of them is the exuviae, which is resulted from the emergence of the fly and it has a high chitin content. Chitin from BSF exuviae have low Cristalinity Indexes. Hence, it shows a promising potential to be processed to produce a new biopolimer. Therefore, converting chitin from BSF exuviae into chitosan using deacetylation process was studied. The researched variables were temperature and the duration of the process, which were studied at 50, 60, 70, and 80°C for 12 hours and 8, 10, 12, and 14 hours at 60°C, respectively. Chitosan produced in the temperature of 60, 70, and 80°C has met the standard quality, and the best duration of deacetylation process was 8 hours. The solubility test in acetic acid (2%) showed that chitosan solubility was increased with the increase of temperature, while it decreased as the duration of the process becomes longer. Moreover, the degree of deacetylation showed that chitosan was produced with the best quality in 80°C of temperature (75.98%) and 8 hours of deacetylation process (71.12%). Keywords: chitosan, degrees of deacetylation, exuviae of black soldier fly

Abstract

Catering industry is a food business which produces ready-to-eat food or food that will not be cooked or reheated before serving. Therefore, the safety of food produced by catering industry becomes very important. During period of 2015–2017, the food produced by catering industry was the third largest cause of food borne outbreak in Indonesia. This showed poor compliance level of food hygiene and sanitation in the catering industry, especially during food production. This study was aimed to measure the compliance level of sanitation and hygiene practices during food production in catering industries. This study was carried out in 10 catering industries located in Bogor City, consisting of 2 catering industries in class A2, 4 catering industries in class A3, and 4 catering industries in class B. Data collection was carried out by observation using checklist which was developed from Regulation of The Minister of Health Number 1096 Year 2011. Result showed that catering industries in class A2, A3, and B had an average compliance level of hygiene and sanitation practices during food production. The stage of raw material procurement in class A2 and stage of food processing in class A2, A3, and B were still in poor compliance level of hygiene and sanitation practices that should be more improved.

Abstract

One of the priority watersheds to be managed in Indonesia is the Cisadane watershed due to the high degradation problems. The Cisadene watershed degradation could be indicated by a high river flow during rainy season, low baseflow in dry season, and high erosion and sedimentation. One of the main problems in the Cisadane watershed is a huge landcover changes in the Cisadane Hulu watershed that causes a decrease in water absorption region and a surface runoff. The study aimed to analyze landcover changes in the Cisadane Hulu Watershed during 2013-2018 and analyze the watershed conditions based on their hydrological characteristics. Analysis of landcover changes patterns was carried out by processing spatial data using GIS software. Analysis for hydrological characteristics was conducted by using SWAT modelling (Soil and Water Assessment Tool). The results showed that there were land cover changes during 2013-2018. The most significant landcover changes in the Cisadane Hulu watershed was residential area (455.95 ha). The result simulation scenario of the model SWAT showed scenario 2 was the best scenario for the management of the Cisadane Hulu watershed. The application of Soil and Water Conservation can decrease surface runoff by 32.1% and increase lateral flow by 8.89%. Therefore, it is expected that the results of this SWAT model simulation will be taken into consideration by the local government for the optimal management of the Cisadane Hulu watershed. Keywords: Cisadane watershed, land cover change, SWAT modelling

Abstract

Plants can be used as phytoremediation agents to improve critical land due to gold mining activities. This experiment aimed to analyze the morphophysiological, anatomical, and histochemical responses of Brachiaria mutica, Cyperus kyllingia, Ipomea aquatica, Mikania micrantha, and Paspalum conjugatum in response to the application of heavy metals mercury and lead in the forms of Hg(NO3)2 and Pb(NO3)2 in hydroponic experiments and to determine the ability of these plants to accumulate both metals. Morphological responses were observed by measuring number of leaves and plant dry weight, and physiological responses were observed by analyzing photosynthetic pigments, while anatomical and histochemical responses were analyzed by microscopic observation to tranversal slice of roots and leaves. The results showed that the applications of Hg(NO3)2 and Pb(NO3)2 treatments caused decreases in number of leaves, plant dry weights, and photosynthetic pigments (chlorophyll a, chlorophyll b, and carotenoid). The treatments also decreased leaf thickness due to the decrease in the epidermis, but they caused the increases in exodermis and endodermis of the roots. Mercury and lead were accumulated in large amounts in the roots, but accumulation in the shoot was less. Histochemical observation showed that lead was found in the roots of all the plants, especially in endodermic tissue and the vessel, whereas in the leaves the two metals were detected in the upper and lower epidermis, mesophyll, and vessel. Among the five species tested, C. kyllingia and P. conjugatum were the most tolerant to Pb and Hg.

Abstract

Mangrove litter production is important in the displacement of organic matter from mangrove vegetation to water such as in the coast of West Muna Regency. However, one factor influencing it is the frequency of rainfall. This research, therefore, aims to determine the influence of the frequency of rainfall in mangrove ecosystem by obtaining data through the fractional wet weight. The results showed that the biomass fraction with the largest amount were Rhizophora mucronata, Rhizophora apiculata, and Sonneratia alba with of 31.59; 31.07; and 30.96%, respectively, while the lowest was Rhizophora stylosa, Bruguiera cylindrica, and Bruguiera gymnorrhiza with of 30.07; 30.10; and 31.95%, respectively. The species with the largest leaf litter production was Bruguiera cylindrica, with of 1.72 g.m-2.day-1 which occurred in April and the lowest was Rhizophora apiculata, 0.24 g.m-2.day-1 in August. The species with the largest leaf litter production was Bruguiera cylindrica, 1.96 g.m-2.day-1 which occurred in May and the lowest was Sonneratia alba, 0.29 g.m-2.day-1 in August. In addition, the species with the largest fruit litter production was Rhizophora apiculata, 1.76 g.m-2.day-1 in April and the lowest was Sonneratia alba, 0.32 g.m-2.day-1 in September. The total litter production was 18,75 g.m-2.day-1 consisted of 6,69 g.m2.day-1 leaf litter, 6,54 g.m-2.day-1 branch litter, and 5,52 g.m-2.day-1 fruit litter. The higher the frequency of the rain, the greater the litter production. Keywords: biomass fraction, seasonal litter production, West Muna Regency

Abstract

Seagrass has long been known to be very sensitive to environmental changes, especially caused by human activities (anthropogenic disturbance) and has been used as a bioindicator for environmental condition. This research aimed to study interaction of Thalassia hemprichii measured and derived variables (metrics), at two locations i.e., inhabited island (high anthropogenic location) and uninhabited island (low anthropogenic location). Confirmative approach was conducted using a developed conceptual model based on preliminary studies, the conceptual model was analyzed in multivariate context using data from field observation. The result showed that Thalassia hemprichii dominated and have higher above ground biomass value in inhabited area which indicated high nutrient input, meanwhile uninhabited area showed a higher below ground biomass value. Above ground of Thalassia hemprichii that have direct effect on its biomass and below ground metrics was leaf width, meanwhile leaf length of Thalassia hemprichii have indirect effect on its biomass and below ground metrics. The result also indicated some different metric covariations which were influenced by the degree of Thalassia hemprichii density. Leaf length, leaf width, density, and percent cover of Thalassia hemprichii potentially could be used as components in multimetric index and bioindicator for environmental quality. Keywords: anthropogenic disturbance, path analysis, structural equation modeling, Thalassia hemprichii

Abstract

The objective of this study was to obtain varieties with high yield along with proper morpho-physiological characters under drought condition. Eleven varieties of upland rice i.e., Gilirang, Situ Patenggang, Kalimutu, Aek Sibundong, Batutegi, Towuti, Sunggal, Danau Gaung, Way Apo Buru, Danau Tempe, and Situ Bagendit were characterized based on morphology, physiology, and yield. Non factorial Complete Randomized Block Design was used with three times repetition. Parameters measured were morphological characters, physiological characters, and yield components. Morphological characters measured were plant height, number and area of leaf, shoot dry biomass, tiller number, and total root length. Physiological characters measured were plant growth rate, net assimilation rate, and relative growth rate. Yield components measured were number and length of panicle, number of seeds per panicle, 1000 seeds weight, weights of seed per panicle, weights of seed per plot, and weights of seed per hectare. The results showed that Danau Tempe variety had better characters against drought stress compared to the other varieties with higher yields supported by high plant growth rate, relative growth rate, chlorophyll content and leaf area with low accumulation of proline content and short root length. Keywords: drought, morphological character, upland rice variety, yield

Abstract

Until now there has not been a centralized Wastewater Treatment Plant (WWTP) in IPB, even though there are wastewater treatments in several locations that are scattered in the campus area. Various activities on the Dramaga IPB campus have the potential to produce wastewater, such as laboratory activities, especially chemical and biological laboratories, canteens, offices, and dormitories. The existence of scattered laboratories requires a centralized and integrated WWTP. For this reason, mapping of wastewater distribution is needed to arrange the location of the wastewater treatment plant, within the campus. Interviews with the perpetrators of activities, measurement of wastewater quality, and sampling, were carried out at the work units producing wastewater on the campus of IPB. The distribution of wastewater was grouped according to the location of the work units producing waste and identified the types of waste produced (B3-dangerous and toxic and non-B3), then presented in a map. The map was used as a reference in determining the location of wastewater treatment plants. The results showed that each work unit contributes organic waste that was not too different, the source of inorganic and B3 wastewater distribution followed the location of the laboratory which was also quite scattered in the Dramaga IPB campus area. Based on the distribution of available waste, the presence of wastewater in the campus environment of IPB was divided into two regional groups. Therefore, the location of the wastewater treatment plant was directed at two locations, namely on the Northeast side (IPAL I) and the West side (IPAL II) of IPB campus. Keywords: wastewater characteristics, wastewater distribution, wastewater treatment plant
