Abstract

Saat ini pola konsumsi yang didasarkan pada kegiatan goreng menggoreng meningkat dengan pesat. Tidak ada satupun konsumsi masyarakat yang lepas dari aktivitas menggoreng. Akibatnya muncul ketergantungan luar biasa dari rumah tangga terhadap industri minyak goreng. Kelurahan Maccini Sombala Kota Makassar adalah lokasi yang dijadikan tempat pelaksanaan kegiatan ini karena adanya keluhan dari masyarakat khususnya para ibu-ibu, tentang bagaimana memanfaatkan minyak sisa penggorengan yang mereka hasilkan di rumahnya masing-masing. Melalui topik ini Tim kami bertujuan memberikan penyuluhan dan pelatihan serta pendampingan mengenai bagaimana meningkatkan nilai guna dan nilai ekonomis melalui pemanfaatan limbah minyak goreng (jelantah) yang melimpah di dapur menjadi sabun cuci yang ramah lingkungan. Metode yang digunakan dalam kegiatan Pengabdian ini adalah metode ceramah /penyuluhan mengenai bagaimana mengubah nilai guna dan nilai ekonomis limbah minyak goreng (jelantah) melalui pembuatan / pengolahan sederhana menjadi sabun cuci. Luaran yang diharapkan dari kegiatan ini adalah Ibu-ibu bisa membuat sabun cuci dari limbah minyak goreng (jelantah). Target setelah dilaksanakan pelatihan cukup menggembirakan seluruh peserta pelatihan dan sisanya perlu ditindak lanjuti dengan pendampingan untuk Pengabdian Kepada Masyarakat berikutnya.

Abstract

Prediction of ground movements in the case of continuous subsidence is critically important for the planning of underground mining. Many calculation models are used to predict mining subsidence. A comprehensive method to render current calculation models superfluous can only come from a theoretical model, but the challenge remains in defining the parameters, given the great variety of rock structures found. Hence, innovation through a conceptual and technological study of the subsidence mechanism is needed to ensure that this problem can be solved satisfactorily. In this study, a new method is proposed to predict ground surface subsidence by combining a stochastic medium concept with Geographic Information System (GIS) technology. All subsidence computations are implemented within GIS, where spatial components are used to conduct the subsidence prediction analysis. This paper includes simulations of basic subsidence phenomena and a comparative study of the GIS-based calculation method’s suitability against the empirical method from the Subsidence Engineer Handbook (SEH), semi-empirical influence function models, and numerical modeling. First, the influence of basic extraction area categories on the character of mining subsidence at the surface for flat seam layers is verified. Second, subsidence and horizontal displacement profiles are compared for both gently and steeply inclined mining. Finally, the verification of calculated horizontal strain values for an actual case of inclined irregular mining is also conducted. The comparative results of subsidence predictions for flat and gently sloping mining demonstrate the suitability of the GIS-based calculation method for use in underground mining strategy.

Abstract

The study area is located in the IUP of PT X, which covers an area of ± 1,210 ha. Administratively located in Bombana Regency, Southeast Sulawesi Province. Spatial data analysis in mapping the potential success rate of reclamation and environmental design is carried out based on geological criteria and remote sensing so that the impact of risks in the mining industry can be minimized. This study aims to map the potential success rate of post-mining land reclamation and environmental design in the study area based on spatial analysis with the Analytical Hierarchy Process (AHP) method. The geological criteria used in this study are lithological units, seismicity, hydrology (catchment area), vegetation density distribution, and hydrothermal alteration (iron oxide alteration and clay minerals). The data used in this study are the Kolaka sheet regional geologic map, DEM SRTM, Landsat 8 imagery, and company reports (lithology, reclaimed land openings). The data were analyzed to produce evidence maps of lithology, ranginess, catchment area, and vegetation density distribution using the NDVI technique and hydrothermal alteration using the band ratio technique, then spatial analysis was carried out using the AHP method. The result of this research is a map illustrating the potential success rate of reclamation and environmental design in the study area which is divided into 3 classes, namely: high potential area of 407.52 Ha (36.68%), medium potential area of 360.81 Ha (32.48%), and low potential area of 342.54 Ha (30.84%) of the total area. Based on the validation test of the reclaimed land opening area of 28.63 Ha that corresponds to the area with the result of a high potential success rate of about 89% of the total validation land opening area the results of this modeling are statistically acceptable.

Abstract

The handling of human hair waste is still not optimal, as it is often discarded or burned, leading to environmental pollution. This research aims to utilize human hair waste as a mixture in normal concrete, resulting in a fiber-reinforced concrete product with marketable value, providing a more beneficial use compared to simply being disposed of or burned. The purpose of this study is to analyze the mechanical properties of concrete using human hair fibers. The mechanical properties to be analyzed include compressive strength, tensile splitting strength, and flexural strength. This research is based on laboratory experiments. The variations in the amount of fiber used in the study are 0.25%, 0.5%, 1%, and 1.5% of the cement weight in the concrete mix. Based on the results of mechanical property testing, it can be concluded that the optimal addition of 1% human hair fibers yielded a compressive strength of 22.86 MPa, tensile splitting strength of 2.69 MPa, and flexural strength of 4.13 MPa.

Abstract

Kementerian Perhubungan RI meluncurkan program angkutan massal di kawasan perkotaan berbasis jalan, bernama Bus Rapid Transit (BRT) yang tertuang dalam Peraturan Menteri Perhubungan Republik Indonesia No. PM 15 Tahun 2019. Pada tahun 2021 dimulailah penerapan program angkutan umum massal berbasis jalan di wilayah perkotaan dengan nama BRT Mamminasata (Teman Bus) di Kota Makassar. Keberadaan BRT Mamminasata di tengah-tengah padatnya kendaraan di Kota Makassar peneliti merasa tertarik pada bagaimana efektifitas dalam implemetasi program BRT selama waktu pengoperasiannya. Tujuan dari penelitian ini adalah untuk menganalisis tingkat efektifitas BRT Mamminasata sebagai transportasi massal di Kota Makassar. Metode yang digunakan yang digunakan adalah pendekatan kualitatif dengan tambahan pendekatan kuantitatif dengan metode skala likert untuk menganalisis kuesioner, yang dimana data-data yang dibutuhkan berasal dari data primer dan data sekunder. Hasil penelitian menunjukkan bahwa BRT Mamminasata hingga saat ini belum mencapai efektifitasnya disebabkan beberapa hal mulai dari keterbatasan unit yang ada, lajur yang belum tersedia secara mandiri, halte yang kurang memadai, belum adanya integrasi dengan angkutan penumpang, serta aplikasi yang masih terbatas kegunaannya.
