Detection of seed-borne pathogenic bacteria of northern black wattle (Acacia auriculiformis A. Cunn. ex Â enth.). Intensive research of seed-borne pathogen of A. mangium and A. crassicarpa which have been established in industrial timber estate (HTI) was undertaken in Indonesia, while plantings development of northern black wattle have recently been established in the 1990s. Very limited information available on northern black wattle diseases especially seed-borne diseases. The objectives of this study were to identify seed-borne pathogenic bacteria of northern black wattle and the effects on seed germination. Methods for the isolation of bacteria were by seed soaking, seed griding, blotter test, growing-on test on paper and soil. Identification of bacteria by PCR used 63F/1387R primer. The results showed that seed-borne bacteria of northern black wattle were Paenochrobactrum sp., Ralstonia sp., Burkholderia cepacia complex, Pseudomonas stutzeri, Acinetobacter sp., Alcaligenes faecalis, Salmonella bongori, Escherichia hermannii while pathogenic bacteria cause seedling leafspot were Micrococcus luteus and Burkholderia cepacia complex. Burkholderia cepacia complex, A. faecalis, Acinetobater sp., P. stutzeri, S. bongori and Ralstonia sp. reduced seed germination and increased rotten seed, suggested that they were the pathogenic bacteria of northern black wattle seed. Ralstonia sp. significantly increased the percentage of rotten seed and decreased shoot length and root length. P. stutzeri and S. bongori significantly inhibited the root growth. Paenochrobactrum sp. and E. hermannii were assumed as pathogen with weak virulence due to seed germination, the percentage of rotten seed and vigour index were relatively similar to untreated seed.

One of the determining factors in disease control is the use of superior seeds which have good quality and quantity. The use of biological control agents that form a symbiotic mutualism in their host plants can be used as an effort to obtain quality clove seeds. Endophytic bacteria and rhizobacteria have been reported as potential biological control agents for many plant diseases because of their safety in humans and non-target organisms. The purpose of this study was to identify the physiological and morphological characteristics of endophytic and rhizobacterial isolates obtained from clove plants. A total of 46 endophytic bacterial isolates were isolated from healthy clove roots, stems, leaves and flowers. Also, 66 isolates were isolated from the soil around the rhizosphere area. Based on the results of the identification of physiological and morphological characteristics, it is evident that the endophytic and rhizobacterial bacteria tested have the same character as Bacillus spp.

Laundry liquid waste contains several chemical substances in detergent raw materials such as phosphate, surfactants, ammonia, and total suspended solids. The existence of detergent in high concentrations and exceeds the quality standards that have been estabilished in a body of water can lead to cases of enviromental pollution in the form of increased turbidity an Chemical Oxygen Demands (COD) levels. Therefore in order to maintain and to ensure the availabillity of water in terms of quality, it requires coagulation-flocculation process to laundry liquid waste before discharging into water bodies. This study aims to determine the decrease of COD levels and turbidity level in laundry liquid waste using chitosan coagulant in Rahma Laundry, Tembalang District, Semarang. The research is a quasi experimental study with pretest-posttest with control group research design with 6 times replication. The total samples are 60 in wich 24 tested for the levels of turbidity and 6 controls. The test results of Kruskal-Wallis with significance p-value < 0,05 indicates that dosage variation (p=0,000) gives different levels of COD and dosage variation (p=0,000) provide 755,97 mg/l and the advantage levels of turbidity before treatment was 516,20 NTU. The optimum dosage of chitosan coagulant is on the dose of 200 mg/l with the effectiveness decrease of COD levels and turbidity levels on 72,67% an 98,67% respectively.

Large amounts of waste require special handling to reduce negative impacts. One way to reduce the negative impact of waste generation is waste processing by adding various EM4 as decomposers. The result of organic waste processing of household is leachate compost. The purpose of this research is to know the ability to use different variation of Effective Microorganism 4 (EM4) concentration in composting process. The type of research used is experimental semu (Quasi Experiment). With the design of Time series research with the Control Time Series Design. Total volume of household waste generated at the research location is 908 liters. The composition of waste generation is 378 liters of inorganic waste and 530 liters of organic waste. The percentage of household waste generated in this research is 58% organic waste and 42% of inorganic waste. In this study the average waste generated is 1.7 liters / person. The highest temperature is in the addition of EM4 with a concentration of 4% ie 34.5⁰C. The highest average daily temperature was found in the addition of EM4 2% concentration of 30⁰C. The highest compost volume of compost produced by composter with the addition of EM4 2% concentration as much as 5.9 liters. The average daily volume of the largest compost leachate produced composter with the addition of EM4 with a concentration of 2% ie 0.19 liters / day. Compost volume at least produced composter with the addition of EM4 with a concentration of 2% is 3.5 liters. The largest percentage of waste reduction to compost on the composter with the addition of EM4 with a 2% concentration of 88.3%. Suggestions for households should process organic waste caused into leach compost because it reduces the volume of waste that should be disposed in waste disposal.
