Abstract

The successful energy-saving efforts made by industries impact on not only lowering production costs but also indirectly preserving natural resources as well as reducing the pollution of CO2 which is one of the gases contributing to global warming. Pinch analysis has been widely known for process integration, especially in heat integration, in order to gain energy efficiency and cost efficiency in many industries for decade. The analysis allows selection of efficient heat exchanger network with minimum hot and cold energy requirement. By using pinch analysis, the number of heat exchanger units required could also be minimized which leads to the optimum cost of operational and investment. Pinch analysis is also allowing for the investigation of any pinch problems, such as pinch threshold problems, cross pinch problems, and problems related to incorrect placement of utilities which impacted to the wastefulness of energy consumption. Despite many success studies of highly potential saving of heat integration through pinch analysis, the real implementation of efficient and effective heat exchanger network (HEN) based on pinch analysis is still facing difficulties, for example in term of flexibility and controllability of operation. This paper provides preliminary information in increasing energy efficiency or energy savings when utilizing pinch technology considering operability and flexibility of its operation for retrofitting units for chemical industrial plants.

Abstract

Sumber energi alternatif yang banyak dikembangkan dan diteliti saat ini adalah bahan bakar biomassa dari limbah industri. Biomassa yang berasal dari limbah hasil industri dan kehutanan merupakan bahan yang dapat dimanfaatkan menjadi sumber energi bahan bakar alternatif. Biomassa cocopeat yang merupakan limbah dari industri pembuatan coconet banyak ditemukan akibat pemanfaatan yang tidak maksimal. Sampel cocopeat ini memiliki nilai kalor 4704,6 kkal/kg dan sulfur 0,093% kemudian dilakukan pencampuran dengan batubara dengan nilai kalor 6909,8 kkal/kg yang digunakan pada industri feronikel, namun sebelumnya cocopeat ini dibagi menjadi dua sampel yaitu biomassa cocopeat dan charcoal cocopeat yang telah dipirolisis. Pada proses pirolisis digunakan gas nitrogen dengan laju alir 2L/menit dengan hasil charcoal yaitu dengan nilai kalor 7161,3 kkal/kg. Penelitian ini bertujuan menentukan rasio optimum campuran co-firing biomassa dengan batubara serta menganalisis karakteristik campuran. Hasil penelitian menunjukkan bahwa rasio optimum biomassa cocopeat adalah 10%, menghasilkan nilai kalor 6689,3 kkal/kg dan kadar sulfur 0,721%. Rasio optimum pada charcoal cocopeat juga diperoleh 10%, menghasilkan nilai kalor 6929,0 kkal/kg dan kadar sulfur 0,673%. Kedua rasio memenuhi spesifikasi Rotary Kiln pada industri feronikel dengan batas minimum nilai kalor 6686,25 kkal/kg dan sulfur <1%. Pemanfaatan cocopeat mampu menekan biaya bahan bakar dan emisi sulfur serta mendukung penerapan energi terbarukan..

Abstract

National salt production capacity is dominated by smallholder salt production through the crystallization process in traditional salt ponds. One of the salt producing areas in South Sulawesi Province is located in Jeneponto Regency. Salt farmers in Jeneponto Regency produce salt through traditional salt ponds. Jeneponto Regency is also one of the main coconut producing areas. Coconut coir from the people's plantation industry is currently only used as fuel in small and medium home industries or is simply thrown away as waste. Coconut coir has the ability to absorb water. The aim of this research is to innovate the use of coconut coir waste to increase the surface area for water evaporation in traditional laboratory-scale salt ponds. This research was also carried out by conducting analysis on traditional ponds to study the factors that influence the salting process. Next, the salting process was carried out on a laboratory scale by making a replica of the traditional pond salting process which was equipped with the addition of coconut coir to increase the evaporation surface area. The results of the research show that the salting process in traditional salt ponds is greatly influenced by the season. The sun plays a very important role in the evaporation process in traditional salt ponds until salt crystals form in the ponds. Laboratory scale salt pond equipment shows that the use of coconut coir plays a very important role in speeding up the evaporation process and has the potential to increase salt production in traditional salt ponds.

Abstract

This study aims to analyze the environmental impacts of fish farming activities on the surrounding environment, particularly on the Tallo River and nearby residential areas. The environmental impact assessment focused on water and air quality across various aquaculture sites. Water quality was analyzed through in-situ and ex-situ sampling at four distinct points: Station 1 (upstream of the Tallo River), Station 2 (discharge outlet from aquaculture ponds into the Tallo River), Station 3 (downstream of the Tallo River), and Station 4 (wells within the Panaikang residential area). Three parameters were evaluated: physical (temperature, odor, and color), chemical (pH, DO, BOD, and COD), and biological (total coliform). While the physical and biological parameters met established standards, the chemical parameters fell below permissible thresholds. Specifically, DO, BOD, and COD values at Stations 2 and 3 revealed concerning levels: DO at 3.8 mg/L and 2.6 mg/L; BOD at 3.61 mg/L and 11.7 mg/L; and COD at 36.9 mg/L and 74.1 mg/L, respectively, indicating water pollution attributable to fish farming activities. Air quality assessments, including noise level measurements, were conducted at two points: Station 1 (within the aquaculture area) and Station 2 (Panaikang residential area). Noise levels were measured exclusively in the aquaculture zone. Results demonstrated compliance with regulatory standards for air quality and noise levels, indicating no significant risk of air pollution. A community survey further corroborated these findings, with 77% of respondents affirming that aquaculture activities did not disrupt their daily lives or environmental quality.

Abstract

The Bolaang Mongondow region, especially in Tanoyan Selatan Village within the Lolayan District, presents considerable promise for the extraction of economically significant minerals, including gold ore. In this region, the practice of small-scale gold mining frequently utilizes cyanidation methods, which present significant environmental hazards. This research endeavors to investigate the effectiveness of Lobong lime and Kemindo lime in neutralizing the pH of mining wastewater, with particular emphasis on the impact of lime type and concentration on pH levels. The methodology for treating wastewater entailed the incorporation of lime powder into mining wastewater at diverse concentrations of 0.03 g, 0.04 g, 0.05 g, 0.08 g, 0.10 g, and 0.12 g, accompanied by stirring intervals of 1 minute, 3 minutes, 5 minutes, 7 minutes, and 10 minutes. The results indicated that Kemindo lime consistently surpassed Lobong lime in elevating pH levels. Moreover, the level of lime demonstrated a direct positive relationship with the enhancement of pH; increased lime concentrations led to markedly higher pH values. The findings highlight the essential importance of choosing the correct type and concentration of lime in wastewater treatment to improve both water and soil quality, consequently reducing environmental repercussions.

Abstract

This study aims to determine the effect of the concentration of cocoa peel biosorbent (Theobroma Cacao L) on the decrease of Pb & Cd Metals in AAS wastewater and to determine the effect of cocoa peel extract concentration in inhibiting the growth of Staphylococcus Aureus (S.Aureus) bacteria. Cocoa peel biosorbents were activated with HNO3 0.6 N. Biosorbents with masses of 5 grams, 10 grams and 15 grams were able to absorb Pb and Cd metals in the waste, which absorbed 1.7703 mg/L, 2.1428 mg/L and 2.4868 mg/L respectively from the initial concentration of waste which was 3.0069 mg/L. So that the absorption effectiveness was obtained at 58.87%, respectively.  71.26% and 82.70% where the largest absorption was with the addition of 15 grams of biosorbent and metal Cd in the waste, which were absorbed by 2.0100 mg/L, 2.3538 mg/L and 2.6499 mg/L respectively from the initial concentration of waste, which was 3.0024 mg/L. So that the absorption effectiveness was obtained which was 66.94%, 78.35% and 88.25%, respectively, where the largest absorption was with the addition of biosorbents of 15 grams.
