Tacit knowledge that dominantly exists in the construction project and embed in humans’ minds could disperse after the project team is disbanded at the end of the project. As the result, repeated mistakes could occur, and lesson learned from the previous project is not optimally utilized for the benefit of future projects. Previous studies show that tacit knowledge is still not successfully managed in the construction industry. Hence, this study aims to (1) explore the process and method of tacit knowledge acquisition and codification and (2) explore the barriers of tacit knowledge acquisition and codification in the construction industry. The data was gathered through semi-structured interviews with employees from two leading construction companies that are classified as grade-7 (highest grade) in Indonesia. The data were analyzed using thematic analysis. The findings are expected to enrich the existing project knowledge regarding tacit knowledge acquisition and codification in which could become the basis for future research in the tacit knowledge management areas.

Batik Sidomulyo Batu City is one of the hand-crafted batik Small and Medium Enterprises (SMEs) that uses synthetic dyes. The use of dyeing technology in batik making process generates a large amount of wastewater, which can lead a harmful effect to the environment. To date, Batik Sidomulyo SME uses two types of mori cloth material before dyeing process include mori cloth with and without the mordanting process. The mori cloth with mordanting process was soaked in the alum for 24 hours before the grafting process was carried out. The purpose of this study was to analyze the quality of batik wastewater produced based on the characteristics of the treatment of the fabric material before the embedding process was carried out. Wastewater treatment technology uses technology transfer from Mini Wastewater Treatment Plant (WWTP) which utilizes biofilter technology using two treatment compartment including (1) separation of wax content from wastewater and (2) separation of wastewater from toxic and hazardous material waste by mixing with a coagulant. Measurements of pH, BOD, COD, TSS, and oil/fat were carried out before and after the treatment of Mini WWTP. The results showed that the pH of the wastewater generated from the mini WWTP outlet was following the quality standard of 6.86 and the total suspended solids (TSS) value of 90.16 mg/L. Meanwhile, the values of BOD, COD, and oil/fat content have been significantly reduced but still exceeded that of the quality standards, with the value of 90.16, 253.8, and 4.5 mg/L, respectively.
Batu Sidomulyo蜡染是一家使用合成染料的手工蜡染中小企业(SMEs)。在蜡染工艺中使用染色工艺会产生大量的废水，对环境造成有害影响。迄今为止，蜡染Sidomulyo SME采用两种类型的森布材料染色前的工艺包括森布有媒染法和无媒染法的工艺。采用媒染法的桑布在明矾中浸泡24小时后进行嫁接。本研究的目的是根据织物材料在包埋前的处理特点，分析所产生的蜡染废水的质量。污水处理技术采用微型污水处理厂(WWTP)的技术转让，该工厂利用生物过滤技术，采用两个处理隔间，包括(1)从废水中分离蜡含量，(2)通过混合混凝剂将废水与有毒有害物质废物分离。在Mini WWTP处理前后进行了pH、BOD、COD、TSS和油脂的测定。结果表明:微型污水处理厂出水pH值为6.86，总悬浮物(TSS)值为90.16 mg/L;同时，BOD、COD和油脂含量虽有显著降低，但仍超过质量标准，分别为90.16、253.8和4.5 mg/L。

Coal is used mainly in boiler units as a heat energy generator. The non-renewable nature of coal encourages creating alternative fuels, such as briquettes. The abundance of organic material in dairy sludge has potentially becomes briquettes. To improve the quality of the briquettes, it is necessary to add other biomass with high caloric value, such as coal and coconut shell. Dairy sludge and coconut shell will undergo pyrolysis to produce charcoal later mixed with the coal. The formulation was determined using linear programming, with the decision variables consisting of coal (X1), dairy sludge charcoal (X2), coconut shell charcoal (X3), and binder (X4). The purpose of linear programming is to maximize the heating value of the briquettes and obtain proximate characteristics that suit Indonesian National Standard (SNI 01-6235-2000) for wood charcoal briquettes. The charcoal yield from pyrolysis was 44.35% for dairy sludge and 27.8% for coconut shell charcoal. The optimal briquette formulation was 10% coal, 10% dairy sludge charcoal, 75% coconut shell charcoal, and 5% adhesive. The calorific value obtained reached 9247.41 cal/gram. However, the ash content did not meet the SNI 01-6235-2000.
