Mineral pirit merupakan salah satu mineral sulfida yang sangat sering dijumpai di dalam batubara. Kehadiran mineral pirit sangat berpotensi menimbulkan masalah pada kegiatan penambangan dan pemanfaatan batubara. Terkhusus pada kegiatan penambangan, mineral pirit berpotensi menimbulkan air asam tambang (acid mine drainage) dan pada pemanfaatannya menimbulkan dampak negatif terhadap lingkungan. Permasalahan tersebut melatarbelakangi penulis untuk melakukan kegiatan penelitian dan analisis terhadap karakteristik mineral pirit yang terkandung pada batubara di Desa Massenrengpulu, Kecamatan Lamuru, Kabupaten Bone, Provinsi Sulawesi Selatan. Metode yang digunakan dalam penelitian ini adalah analisis mikroskopi (petrografi), ultimat (total sulfur) dan X-Ray Diffraction. Hasil analisis mikroskopi menunjukkan bahwa mineral pirit pada batubara di bawah mikroskop terlihat dalam keadaan bebas (tidak terikat) dan tidak terinklusi oleh mineral lain. Kenampakan di bawah mikroskop juga memperlihatkan adanya mineral kuarsa yang diinklusi oleh mineral karbonat. Kenampakan mineral pirit (FeS2) (iron sulfide) memperlihatkan warna krem pucat, isotropik, relief tinggi, berbutir halus, tersebar tidak merata pada massa maseral. Hasil pengamatan mikroskop menunjukkan bahwa bentuk mineral pirit yang dominan adalah bentuk pirit framboidal yang terdiri dari kristal oktahedral, ukuran halus dan speroidal. Hasil analisis XRD memperlihatkan mineral pirit terdeteksi dalam difaktogram pada semua conto batubara ML-1, ML-2A, ML-3, ML-4 dan ML-F. Pada sampel ML-1 terlihat peak tertinggi dengan sudut 2θ 33.26o dan intensitas 2.6195Å. Pada Conto ML-1 juga terlihat di sudut 2θ 57.982o dengan intensitas 1.5893Å dan peak pirit masih sangat mendominasi dan mempunyai sistem kristal isometrik. Hasil analisis ultimat (total sulfur) conto batubara yang diteliti memiliki kandungan sulfur minimum 1,54% (sampel ML-F) dan maksimum 11,86% (sampel ML-1). Rata-rata kandungan sulfur total pada sampel batubara di daerah penelitian memperlihatkan nilai rata-rata sebesar 5,18%. Hal ini menunjukkan bahwa batubara yang dianalisis dikatagorikan sebagai batubara dengan kandungan sulfur yang tinggi. Mineral pirit merupakan mineral sulfida yang paling umum dijumpai pada batubara dan memberikan kontribusi yang besar terhadap kandungan sulfur pada batubara. Berdasarkan hasil analisis yang telah dilakukan, karakteristik pirit pada batubara yang terdapat di daerah penelitian berpotensi memicu terbentuknya air asam tambang dan dapat menimbulkan masalah dalam pemanfaatannya.Kata Kunci: batubara, mineral pirit, total sulfur, mikroskopi, XRD, air asam tambang.

Daerah Lamatti Rilau-Sinjai Utara merupakan daerah dengan bentang alam yang berbukit-bukit. Kondisi bentang alam tersebut menjadi kendala dalam pemenuhan kebutuhan air irigasi pertanian dengan pemanfaatan air permukaan. Oleh karena itu, diperlukan pengembangan air tanah untuk mensuplai kebutuhan air irigasi tersebut sebagai upaya peningkatan produksi. Pengembangan sumber daya air tanah terdiri atas beberapa tahapan, namun hal yang paling mendasar adalah identifikasi keterdapatan air tanah di bawah permukaan. Metode investigasi yang sangat popular adalah pengukuran tahanan jenis batuan. Nilai tahanan jenis batuan merupakan representasi dari variasi karakteristik fisik dan kimia batuan. Oleh karena itu, hubungan antara jenis batuan dan nilai tahanan jenis merupakan dua hal yang menjadi dasar analisis dalam kegiatan ini. Daerah Lamatti Rilau – Sinjai Utara tersusun atas material batuan sedimen Formasi Walanae(Tmpw), Batuan Gunungapi Lompobatang (Qlv) dan Endapan aluvium dan pantai (Qac). Pengamatan lapangan menunjukkan sejumlah singkapan batupasir yang berpotensi sebagai lapisan pembawa air. Nilai tahanan jenis batuan tersebut bervariasi dari 2,0 – 104,0 ohm-m. Variasi nilai tersebut menunjukkan bahwa pada kedalaman tertentu terdapat lapisan pembawa air tanah. Dari 3 titik investigasi geolistrik, titik GL-3 merupakan lokasi yang dapat lakukan pengembangan sumur produksi air tanah dengan kedalaman sumur 100 m.

Big flood disaster in South Sulawesi Province has occurred on January 22 and 23 2019. This event is one of the disasters that is quite severe for the City of Makassar and its surroundings. This incident encouraged the community service team to serve the community. Community service program UNHAS-Community Partnership Program (PPMU-PK-M) has partnered with one of the business units (UD Prima Teknik) which is engaged in fence welding and building maintenance needs. UD Prima Teknik is located in Antang Village, Manggala District, Makassar City. UD Prima Teknik is a partner who has helped the community service team in designing mobile stoves fueled with coal and biomass briquettes. The stove that has been designed has been socialized and used for cooking needs in meeting food needs in disasters areas. This stove is designed from iron, strong, resilient, and easy to carry anywhere (especially to disasters areas). The fuel used on the stove is coal, wood or wood charcoal (biomass) briquettes. The choice of fuel, besides being easy to carry on a trip, is also a very low risk of danger compared to gas stoves that are mostly used by the community at this time. If in conditions of limited fuel briquettes and wood charcoal, then this stove can also use wood fuel that is in the vicinity of the disaster area. In disaster conditions in an area, the difficulty that is often experienced by the community is the difficulty of the supply / assistance of ready-to-eat food because of limited kitchen facilities (tools for cooking).

In Bukaka area, Bone Regency, South Sulawesi, Indonesia, a small scale industry of red-bricks with clay as the raw material is exist, which have been operated by the local people in generations for decades. From field observation, a problem was identified related to the quality of the bricks produced, which mostly not fulfilled the quality standards. The purpuse of this community service activiy is to conduct a series of laboratory tests to define and formulate recommendations in order to improve the quality of the raw material and the bricks. Methods of laboratory works performed in this activity include mineralogical analysis (XRD) and chemical analysis (XRF) for clay samples, as well as dimension test, baking test, colour, saline content, absorbtion, compressive strength and sound test for the bricks. The results showed that the clay material composed of feldspar, quartz, kaolinite, and calcite; with high content of iron (Fe2O3 up to 8.85%), thus it is recommended to conduct a decreasing grade of the iron content using magnetic separator method. Dimension of the bricks produced by the local workers were generally far above the quality standard; thus it is recommended to conduct an increasing size of the bricks, particulary in their thickness and width. For the bricks baking, it is recommended to perform an increasing temperature and duration of the baking in order to gain a better quality. Absorbtion of the bricks were also averagely low, 0.5-0.6 gr/dm2/minute, thus it needs to be treated carefully at the time of the raw material mixing. Uncompressed strength test of the bricks resulted average value of 24.47 kg/cm2, which indicated a Class-25 type of the bricks, and having a good quality of sound.

An investigation of mineralogy and chemistry of saprolitic nickel ores developed on ultramafic rock with different serpentinization degree from Soroako, Sulawesi has been conducted using X ray diffraction, thermal analysis, FTIR, and ICP-AES. The implication for the processing of these ores under acidic media was also studied. Weathering of unserpentinized peridotite in the Soroako west block produces saprolitic ore containing minerals such as relict olivine, goethite, quartz, talc with minor serpentine and smectite; whereas the weathered materials overlaying serpentinized peridotite in the Petea area are mainly composed of residual serpentine with lesser chlorite, maghemite, and remnant pyroxene and amphibole. Chemical analysis determined by ICP-AES demonstrates that west ore is higher in Si, Mg, and Ni, as compared to that Petea ore. Conversely, Fe and Al concentrations are higher in Petea ore than in west block ore. SEM-EDX examination reveals that olivine, talc, serpentine and goethite are the Ni-bearing phases occurring in west block ore; while serpentine is the principal host for Ni in the Petea ore. Chemical leaching under sulfuric acid reveals that olivine has highest dissolution rate in the west ore followed by serpentine; while talc, pyroxene, and iron oxides have slow dissolution rates. In contrast, serpentine in Petea ore is easily dissolved and is followed by chlorite; whereas amphibole, pyroxene, and maghemite are difficult to leach. Quartz is present in both ores and it seems to be undissolved during the chemical leaching. It is shown that Ni recovery from Petea saprolitic ore is higher than that of West Block ore.

In Indonesia, gold is typically mined out from epithermal, porphyry and skarn deposit types occurred within volcanic belts along magmatic arc or active continental margin setting. Numerous gold prospects, however, are recently discovered in association with metamorphic and sedimentary rocks. This paper is aimed to discuss a preliminary study on the occurrences and characteristics of the sedimentary rock-hosted low-sulfidation (LS) epithermal gold mineralization in Bastem (Bessengan Tempe) prospect, Luwu district, Sulawesi Island, Indonesia. Detailed geological and hydrothermal alteration mapping was performed to understand the distribution and characteristics of ore mineralization. Representative ore samples taken were analysed for ore chemistry by means of Fire Assay – Atomic Absorption Spectrometry (FA-AAS) and Acid Geochemical Digest - Atomic Absorption Spectrometry (GA-AAS). The results from this work that the Bastem prospect is stratigrapically occupied by Tertiary sedimentary rocks of Toraja formation, which is adjacent to volcanic rocks of Lamasi formation. Gold-bearing quartz±carbonate veins are hosted by mudstone and siltstone of Toraja formation. The quartz-carbonate veins show a typical LS epithermal open space filling texture containing erratic gold grade of up to 7.16 g/t with relatively high besemetals (Pb and Zn) grades of up to >0.4 and >1%, respectively. Based on those various features, the LS epithermal deposit is categorized as “carbonate-basemetal-gold mineralization type”, which might be originated in back arc rift/basin setting. This ‘unconventional’ sedimentary rock hosted-gold mineralization type would be the new target of gold exploration in Indonesia.

Zeolit adalah mineral aluminosilikat terhidrat yang memiliki struktur berongga sehingga dapat digunakan sebagai bahan penyerap. Sifat absorben zeolit ini berguna dalam menyerap zat-zat beracun seperti amoniak dan logam berat, sehingga dapat digunakan sebagai imbuhan pakan ternak, tambak, penjernihan air limbah dan penjernihan minyak kelapa sawit. Akan tetapi, umumnya zeolit yang digunakan merupakan jenis zeolit alam yang memiliki rasio Si/Al rendah dan kandungan mineral pengotor yang relatif tinggi sehingga dapat mengurangi kemampuan absorpsi zeolit. Salah satu metode aktivasi zeolit adalah dealuminasi secara kimia yaitu proses penurunan kandungan Al pada struktur kristal zeolit untuk meningkatkan rasio Si/Al. Tujuan penelitian ini adalah untuk mengetahui komposisi mineralogi dan kimia zeolit. Selanjutnya percobaan dealuminasi zeolit dilakukan dengan menggunakan pelarut asam sulfat dengan variabel konsentrasi dan suhu. Hasil analisis menunjukkan zeolit mengandung mineral feldspar, klinoptilolit, mordenit, dan kuarsa, Komposisi kimia didominasi oleh SiO2 dan Al2O3. Hasil percobaan menunjukkan rasio Si/Al mengalami kenaikan dari 1,09 menjadi 1,29 yang diperoleh pada konsentrasi H2SO4 1,5 M dan suhu 100.

This community service activity has been carried out at the Miftahul Jannah Putri Tahfidzul Qur'an Islamic Boarding School in Pamanjengan, Moncongloe, Maros Regency. This Islamic Boarding School for Qur’an Memorizer fosters 10 children from families with underprivileged economic conditions. The capacity of the pondok buildings can accommodate more number of students, but water supply is a big problem. Therefore, the management of the school has attempted to add groundwater production wells through financing from other parties. Drilling was carried out to a depth of 60 meters. The well pumping test with a discharge of 1,440 liters/hour showed a change in the groundwater level to become static at a decrease of 1.60 meters. Thus, the condition prior to this community service activity was that there were production wells but had not been equipped with submersible pump wells. Information from the pre-test indicated that the students still felt limited clean water. Therefore, through Hasanuddin University's P2C-IKU activities, pump installations are carried out to be able to utilize groundwater from the drilled wells. The results of the post-test at the end of this activity showed that 83.30% of respondents believed that there would be sufficient water supply to meet the needs of the cottage, and 57.14% of respondents understood how to operate and maintain submersible pumps.

Community service activities UNHAS-Community Partnership Program (PPMU-PK-M) has partnered with the community and coal miners in Sengengpalie Village, Lamuru District, Bone Regency, South Sulawesi Province. The partners involved in this socialization and development are a community group called the “Mario-Mario Community Forum”. Partners involved contribute as participants and facilitators in the implementation of community service activities (PkM). This PkM activity is in the form of socializing and fostering Good Mining Practices for miners and the community around coal mines. Environmental problems and post-coal mining land conditions at community service (PkM) locations pose enormous problems and risks. These problems include the formation of acid mine drainage which is very dangerous to the environment and the lives of people and other living things around the mining area. The second problem is the opening of pits/voids that are not properly reclaimed. The Unhas PkM team on this occasion will be presented with the community and coal miners to find solutions and anticipate possible problems that will arise due to coal mining activities in the future. The solution offered is to provide guidance to miners and the community around the coal mining area to apply Good Mining Practices (GMP) so that miners and the community work together in the implementation of coal mining from the initial stage (planning) to the reclamation stage (post-work). This socialization and development of Good Mining Practice is expected to contribute to producing Good Mining Practice practices for the target audience (miners and the community) in the mining area. The post-mining land area in the service area can be managed jointly by implementing a good environmental monitoring and management plan. Thus, acid mine drainage in post-mining areas can be prevented and post-mining holes (void) can be reclaimed properly and can be used for its designation for communities in post-mining areas. The reclamation activities are directed at turning the post-mining land into rice fields, cattle and goat areas or plantation areas. The results of the quantitative analysis of the pre-test and post-test showed that there was an increase in the knowledge/understanding of the participants by 43% to know/understand and 37% to really know/understand Good Mining Practice. The increase in the percentage of respondents' knowledge shows that the implementation of this community service activity can be said to have reached the target, namely coal miners and the community have understood and understood GMP or Good Mining Practice.
