Abstract

This research aims to determine the quality of Bengkenang River based on the physicochemical factors and macroinvertebrates community. The measuring of physicochemical parameters was carried out at three stations, namely Sukarami Village, Durian Seginim, and Padang Burnai with two periods for each station: April 2019 following the peak of the rainy season and September 2019 following the peak of the dry season. The physicochemical factors were analyzed descriptively, while macroinvertebrates community were analyzed as the indices of Shannon-Wiener diversity index (H’), Ephemeroptera-Plecoptera-Trichoptera (EPT), and Family Biotic (FBI). The temperature, dissolved oxygen, degree of acidity, and total dissolved solids of this river in each station were in the normal range. This study found 611 individuals of macroinvertebrates that were divided into 21 species (21 families; 4 phyla; 5 classes). The highest species abundance was Epeourus aculeatus, 22.42% of the total sample.  The H’ index from up- to downstteram were 1.79; 2.03; 1.80 respectively, indicating the Bengkenang River is slightly to moderately degraded. The total number of EPT individuals was 305, with mostly found at the downstream and dominated by Heptaginidae (Ephemeroptera). The FBI values were 3.81; 4.18; and 4.33 showed that the quality of the water is “very good”. Based on this physico-chemical factors, H’, EPT, and FBI data, it can be concluded the Bengkenang River is in a good quality.

Abstract

 The research was took place in Post Administrative of Vera Cruz, Dili City, Timor Leste. Vera Cruz is one of the 5 (five) post administrative that located in Dili City. The purpose of this study was to examine the quality of well water in the research area, considering that the government supply of clean water to Dili City could not fulfill the needs of the community. By understanding the quality of well water for the community daily consumption, the community might be more confident or able to treat the well water so that it was safe for consumption. Well water samples were taken randomly from 4 villages of Vera Cruz Post Administrative. Well water quality was analyzed in the laboratory with 6 (six) parameters, including Mn, Fe, and microbiology. In addition, the distance of the well to the source of pollutant and the local geological conditions were studied to find out their influences to the quality of the well water. Referring to several standards of drinking water quality from both Indonesia and Timor Leste, it was known that well water in Vera Cruz Post Administrative has not been yet suitable for direct consumption because it was affected by domestic polluting sources and local geological conditions. Therefore, the well water should be treated before consumption.

Abstract

Shrimp growth patterns will dynamically affect feeding patterns and organic waste conversion in the pond ecosystems. The purpose of this study was to determine the dynamic correlation between the amount of shrimp biomass, feed, and the solubility of organic matter in the shrimp pond ecosystem at the Salafiyah Syafi'iyah Islamic Boarding School Sukorejo, Situbondo Regency. The research method used is an ex-pose facto causal design with time series field data collection. The data taken are water quality parameter, pond water organic matter parameters, feeding data, shrimp sampling data. The results showed that the water quality parameters in aquaculture ponds were still quite good, namely pond A1 pH value 8.2, temperature 29.20C, dissolved oxygen 5.58 mg/L, salinity 25 ppt, and brightness 37 cm. For pond A2, the pH value is 8.1, the temperature is 29.20C, the dissolved oxygen is 5.52 mg/L, the salinity is 25 ppt, and the brightness is 34 cm. From the results of dynamic modeling analysis, it is found that there is a close correlation between the feeding process and the amount of waste generated in the pond with a ratio of 1: 2.86. then the process of shrimp growth rate is correlatively strongly influenced by the factor of feeding which is carried out in an aggregated manner. Based on the results of this study, it can be concluded that according to the interpretation of the results of the analysis of the dynamic modeling system, there is a positive correlation between the increase in the amount of shrimp biomass with the quantity of feed and the abundance of organic matter in the pond which is estimated to take place in an aggregate manner.

Abstract

The waste in the trash is still mixed, and in its management, the waste is not processed and transported immediately to TPA Jatibarang. Sustainable waste management needs to pay attention to 5 aspects of waste management, namely operational technical aspect, institutional aspect, financing aspect, legal and regulatory aspect, and community participation aspect. The purpose of this study is to obtain an integrated waste management concept from the 5 aspects of waste management. The method used in this research is descriptive qualitative, the data is taken using observation, interview, and documentation techniques. It is known that the waste generation on campus 2 is 129.36 kg / day with a volume of 1,903.98 l / day. Composition of food waste 15.74%; wood and garden waste 48,12%; plastic 9,19%; metal 0.20%; paper / cardboard 9.05%; fabrics / textiles 0.30%; glass / glass 0.41%; rubber / leather 0.42%; and other 16,56%. The operational technique of waste management is planned to use 5 separate bins based on waste types, collection using a three-wheeled open motorbike, transfer to TPST on Kampus 2, then composting the food waste and garden waste. Plastic, paper, metal, glass, and rubber can be deposited into Bank Sampah at UIN Walisongo, while cloth and other waste are disposed to TPA Jatibarang. On the regulatory aspect, there are no regulations at the university level governing waste management. In the institutional aspect, it is necessary to carry out technical training for cleaning personnel regarding solid waste management, as well as institutional strengthening. In the aspect of financing, the cost of waste management is budgeted in the Rencana Belanja dan Anggaran which is proportional to the generation of waste every year. In community participation aspect, it is necessary to conduct socialization and education to the entire academic community of UIN Walisongo to increase awareness and participation in waste management.

Abstract

It is necessary to choose the right planting media for vegetable cultivation with a fertigation system. Modification of growing media at various intervals of nutrition can be recommended. The study aimed to 1) analyze the interaction effect of the modification of planting media at various intervals of nutrition on the growth and yield of belinjan tomatoes in the fertigation system, 2) analyze single the effect of each treatment, 3) determine the best combination of treatment. This research was conducted in a greenhouse by using a pot through the treatment of a Split Plot Design. The first factor as the main plot is the interval of nutrition (B) consisting of 3 levels: b1 (3 times a day), b2 (5 times a day), and b3 (7 times a day) and the second factor as a sub-plot is the modification of planting media (A) the ratio of burnt husks: manure: cocopeat the ratio consists of 4 levels: a0 (burnt husk), a1 (2:1:1), a2 (1:2:1), and a3 (1:1) 1:2). The results showed that there was an interaction effect of treatment on the main plot and sub-plots at intervals of nutrition and modification of planting media on the variable of Brix level of belinjan tomato. The single factor of modification of the planting media affected the average number of fruits per bunch, the relative growth rate of 59-73 days after planting and the root shoots ratio. Combination of treatment 7 times per day of the interval level of nutrition with 100% of the burnt husk media resulted in tomato Brix levels at an average level of (5.70) better than other combinations.

Abstract

In heavily populated urban areas, high rainfall can cause inundation and even flooding because the catchment area is decreasing. To reduce rainwater runoff and increase groundwater recharge, porous concrete can be used in housing area, in parking lots and roads with low traffic loads. Porous concrete is an environmentally friendly and sustainable building material. This study aims to examine the effect of aggregate composition on the porosity and tensile strength of porous concrete. The composition of the concrete mixture is determined based on the weight ratio between portland cement type I (PC) and coarse aggregate (AK), i.e. 1 PC : 3 AK, 1 PC : 4 AK, and 1 PC : 5 AK and the ratio of fine aggregate weight (AH) of 0 ; 0.5 ; 1, and the w/c is 0.5. For each variation, six 150 mm cubes were made. The parameters tested were slump, volume weight, porosity and compressive strength at day 28. The results show that the more coarse aggregate, the lower the volume weight and its compressive strength, and the higher the porosity and slump. Fine aggregate addition increases the compressive strength and volume weight and decrease slump value and porosity. The highest slump value (205 mm) and the smallest volume weight and compressive strength were obtained from concrete mixture with PC/AK=1/5 without AH content. The smallest slump (170 mm) and porosity values were obtained from concrete mixture with PC/AK=1:3 and AH/AK=1 and the largest volume weight and compressive strength. In this study, the slump value tends to be directly proportional to porosity and inversely proportional to volume weight and compressive strength. For further research, it is recommended that the w/c value be reduced to get a larger porosity value but without a significant decrease in compressive strength.
