Abstract

This research was conducted by mixing coal and Low-Density Polyethylene (LDPE) waste. This study aimed to determine the smoke resulting from burning briquettes with a calorific value of 9,187 Kcal/gr. Judging from the emission levels of carbon monoxide (CO), sulfur dioxide (SO2), and nitrogen oxides (NO2), it becomes a consideration for the feasibility of briquettes be produced as alternative fuels, harmful or not for human health and the surrounding environment. They are first testing the quality of the briquettes and the smoke emissions from burning briquettes. From the test results, the sulfur content is 0.01%, the moisture content is 1.15%, the ash content is 10.22%, the volatile matters are 87.76%, and the calories are 9187.64 Kcal/gr. Then the smoke resulting from burning briquettes was tested for emission levels of carbon monoxide (CO), sulfur dioxide (SO2), and nitrogen oxides (NO2). The results obtained with a high value and exceed the maximum standard that has been set by PERMEN ESDM No. 047 of 2006, namely CO 13715 mg/Nm3 and SO 2550 mg/Nm3, while the NO 2 produced does not exceed the maximum standard set by PERMEN ESDM No. 047 of 2006 which is 7 mg/Nm3. Based on the test results, it can be concluded that the briquettes produced have the potential to pollute the environment and are dangerous if inhaled at high levels by humans. The resulting briquettes are also unfit to be produced as an alternative fuel.

Abstract

PT Kalrez Petroleum Seram Ltd is a company engaged in the oil and gas mining sector. The company started operations in 2001 and is part of South Sea Petroleum Holdings Ltd, based in Hong Kong. This study aims to analyze the base sectors that can support economic growth and examine the potential of the mining and quarrying sector in supporting economic development in the region. The data used in this study is secondary data obtained from various related agencies, one of which is the Central Statistics Agency (BPS). The data analyzed includes the Gross Regional Domestic Product (GDP) of Eastern Seram Regency and Maluku Province based on constant prices by business field in the 2011-2020 period. This study uses Location Quotient (LQ) and shift-share analysis methods to identify the base sector and analyze the dynamics of economic growth. The results of the analysis show that the base sectors in this area include the fisheries, forestry, and agriculture sectors with an LQ value of 1.06; mining and quarrying sector with an LQ value of 11.37; real estate services with an LQ value of 1.13; and health services and social activities with an LQ value of 1.07. However, the growth of the value of GDP in the mining sector during the 2011-2020 period experienced a significant decrease, namely -6,323.94 million rupiah. Other growth indicators, namely the Proportional Growth Contribution (KPP) of -0.22 and the Regional Growth Contribution (KPPW) of -0.14, also show that the mining and quarrying sector is relatively slow in growth, although it remains competitive at the regional level. The decline in the value of KPP and KPPW with a negative sign (-) in the mining and quarrying sector confirms that this sector is experiencing suboptimal growth. Although its competitiveness is relatively still there, this persistent decline indicates the need for more attention to improving efficiency and innovation within the sector. This is important so that the mining and quarrying sector can contribute more to improving the regional economy in a sustainable manner. To support the development of this sector, strategic policies, investment in technology, and synergy between the government and industry players are needed to overcome existing challenges

Abstract

Dalam dua tahun, Indonesia berencana untuk menambah 30 smelter nikel baru, untuk beberapa di antaranya khusus dirancang untuk menghasilkan nikel baterai. Lingkungan perairan akan menjadi sasaran milyaran ton limbah beracun yang akan di buang ke perairan, salah satu bahan pencemar utama yang terkandung dalam buangan limbah adalah logam berat yang beracun. Adanya logam berat di perairan berbahaya baik secara langsung terhadap Kesehatan manusia, hal ini berkaitan dengan sifat-sifat logam berat yaitu sulit terurai, sehingga mudah terakumulasi dalam lingkungan perairan seperti biota air atau sedimen laut, bahan pencemar logam bila konsentrasi atau keberadaannya tidak terkontrol dapat meracuni biota air maupun manusia. Kualitas air laut yang dig unakan untuk biota laut dan aktivitas lain secara ideal harus memenuhi standar, baik secara fisik, kimia, dan biologi. Kualitas air laut yang meliputi faktor fisika, kimia, dan biologi perlu dimonitor secara kontinu untuk mengetahui kondisi suatu perairan. Pentingnya dilakukan monitoring karena pertumbuhan biota-biota di laut dipengaruhi oleh kondisi kualitas air laut. Setiap jenis biota laut memiliki sensitivitas terhadap parameter-parameter kualitas air laut tertentu. Sehingga, peneliti berinisiatif untuk menganalisis pencemaran logam yang terjadi di perairan sekitar kawasan industri Bantaeng, dengan menggunakan analisis kandungan unsur logam pada perairan tersebut. Untuk mengetahui konsentrasi dari logam tersebut kita menggunakan analisis Atomic Absorption Spectrometer (AAS). Dari hasil analisis tersebut didapatkan unsur logam tembaga (Cu) yang melebihi standar baku mutu air laut, logam timbal (pb) melebihi standar baku mutu air laut, logam raksa (Hg) melebihi standar baku mutu air laut, dan untuk logam nikel (Ni) tidak memiliki standar baku mutu pada area Pelabuhan.

Abstract

Limestone mining for cement plants uses a blasting method to break the material. Blasting production is considered successful when it can achieve production targets based on tonnage of uncovered rock, efficient use of explosives, grain size or rock fragmentation, and environmental impact. This research aims to analyze the blasting geometry on the production results at the research location by knowing the initial design, the actual blasting geometry, and the geometry recommendation using the C.J. Konya method. In addition, researchers also know the explosives used, the production results in the form of material fractionation using the Kuz-Ram method and the tonnage of uncovered rocks. The initial design with a burden of 3.4 m, spacing of 3.4 m, hole depth of 5.9 m, and ANFO explosives per hole of 33 kg produced 147.31 tonnages. The actual geometry with a burden of 1.7 m, spacing of 3.5 m, hole depth of 6.0 m and ANFO explosives per hole of 26.73 kg produced a 77.11 tonnage. The actual geometry resulted in a blasting production of 6,941 tonnes per day, which did not meet the company's production target 10,639. The fragmentation calculation results obtained an average size in the field of 15.29 cm, which meets the required screening or sieve criteria of 0.80 - 1.00 m. The size of the fragments also follows the sieve calculation using the Kuz-Ram method, with a 100 cm sieve passing only 0.01%. Based on this, the company is recommended to make geometry changes to achieve the production tonnage target that has been set.

Abstract

Pattappa Village is a village that has the potential for minerals. However, in developing its potential, residents tend to ignore it because they do not know how to manage it. Residents only know that to manage it, they must attract investors. The uniqueness of the mineral excavation potential can be encouraged from a tourism perspective. This can ensure sustainability compared to mining, which has a management life. Community empowerment activities aim to provide an understanding of the potential of mineral excavation-based tourism owned by the village. The implementation is by conducting socialization, filling out questionnaires, and discussing the evaluation of questionnaire results. The activity results showed a paradigm shift in villagers’ development of tourism potential. Residents have the awareness to manage the potential of minerals in geotourism.
