Publisher : Center for Journal Management and Publication

Domestic wastewater contains high organic matter and nutrient. These compounds can be harmful for the environment if discharged directly to water bodies. Hybrid Anaerobic Baffled Reactor (HABR) technology might be a solution to overcome this problem. The present study aimed to investigate HABR technology for removal COD and ammonia in domestic wastewater. The HABR technology used 7 compartments with a suspended and an attachment system. Design of HABR reactor with is arranged in a series of laboratory scale with a size of 90 cm x 20 cm x 30 cm using activate charcoal (AC) and zeolite (ZE) media. The data collection process is carried out 5 days after seeding and acclimatization period. The collected data is presented in the form of table and figure containing data on the reduction of pollutant levels and efficiency. The highest COD removal value up to 63.77% and 57.22% occurred in AC dan ZE, respectively. The final COD concentration in AC dan ZE media was 67.75 mg/L and 80.00 mg/L. The highest ammonia concentration removal occurred in AC and ZE value up to 68.98%. and 73.47%, respectively. The final ammonia concentration in AC media and ZE was 9.37 mg/L and 8.01 mg/L. The final COD and ammonia concentrations in all treatments met the requirement of domestic wastewater quality standard according to Minister of Environment and Forestry Republic of Indonesia Decree No. 68 of 2016, where the COD and ammonia concentration should be 100.00 mg/L and 10.00 mg/L, respectively.

Malang and Wonosari areas are located in Southern Mountains of Java, and their rock variations are comparable. Study focuses on limestone found at Sumbermanjing Wetan, Malang, that has been identified as part of Wonosari Formation. This place is closer to Punung area as viewed from the type location. Limestone microfacies approach is used to determine whether the limestone belongs to Wonosari or Punung formations. Methods used to identify standard microfacies types and facies zone are measured stratigraphy, petrographic analysis, and microfossil analysis. Measured stratigraphy was conducted along Bangbang River, and seven limestone samples were collected for analysis. Findings showed three standard microfacies types: SMF-5 characterized by packstone or rudstone with a mudstone matrix, SMF-8 characterized by wackstone or floatstone with complete fossils, and SMF-18 characterized by grainstone or packstone with abundant foraminifera or algae. Limestone belongs to facies zone (FZ) 7 - 8, which is characterized by presence of packestone, wackestone, clay sized limestone, and benthic algae foraminifers. Limestone ages range from Middle to Upper Miocene (N12 - N16), were formed in an inner Neritic. Limestone is equivalent to Wonosari and Punung Formations, based on standard microfacies type, facies zone, and age range. When lignite intercalation are present, the limestone is equivalent to the Punung Formation.

The large number of nypa (Nypa fruticans Wurmb) fruit bunches that are carried away by the river indicates that this fruit has not been fully utilized by the community. This study aimed to measure the ratio of filled nypa fruit and determine the rendement of flour from ripe and filled nypa fruit. Ten ripe fruit bunches from 5 clumps were taken from Bunipah Village, Kandangan Lama Village, and Kuala Tambangan Village, Tanah Laut Regency, Indonesia respectively. The fruits were removed from the bunch, sorted according to content, and counted. After the filled fruits were halved, each endosperm was removed from the shell and weighed. The endosperm was then grated. The result was dried through exposure to sunlight for 3 days and pounded. The resulting flour was filtered, dried again through exposure to sunlight for 2 days, and weighed. Main data from the series of steps were the number of filled fruits as well as empty fruits each bunch, the weight of endosperm, and the weight of flour obtained. The normality of the data was tested by the Liliefors test and homogeneity by the Bartlett test. Diversity was analyzed by randomized block design (3 treatments, 3 replications). The ratio of filled fruit referred as the ratio of the number of filled fruits to the total number of fruits on the bunch, while the rendement of flour referred as the ratio of the weight of flour produced to the weight of processed endosperm. The ratio of filled fruits in Bunipah Village (75.83%) and Kandangan Lama Village (75.46%) were higher than in Kuala Tambangan Village (28.55%). The rendement of nypa fruit flour from the highest to the lowest came from Kandangan Lama Village (30.71%), Bunipah Village (30.27%), and Kuala Tambangan Village (25.57%). This rendement was obtained through grating.

The Tambak Anyar polder is one of the many traditional polders scattered in the Banjar Regency. Nevertheless, this polder is flooded almost every year. The purpose of this research is to evaluate dependable discharge that entering to polder system that can be supported by the river capacity inside the polder for flood mitigation. The method used to estimate the water availability is the Mock Model. Furthermore, the data needed are observed discharge, rainfall, and evapotranspiration data. The results of water availability analysis shown that the maximum dependable flow Q80% obtained is 4.89m3/s in the 1st period of January, and the minimum dependable flow Q80% is 1.37 m3/s in the 2nd period of September. The discharge entering the polder is quite large; the capability of Tambak Anyar River as a conveyor channel only can collect 29.74% from the dependable discharge, while the Rantau Bujur River only can accommodate 7.47% in April. In May, Tambak Anyar River's capability can only collect 7.17% from the dependable discharge, while the Rantau Bujur River can only accommodate 0.81%. The amount of discharge cannot be supported by the conveyor river inside the polder. The paddy fields in the Tambak Anyar polder often overflow caused by excess water. This excess of water caused floods that inundated the polder area and the other areas in Banjar Regency as of the beginning of January 2021. The amount of water that has access to the polder is not counterbalanced by watergates facilities and infrastructure management.
