Abstract

Penelitian ini mengenai karakteristik tanah pada areal perencanaan pengolahan sampah. Metode yang digunakan adalah SPT, CPT dan uji laboratorium. Hasilnya adalah sebagai berikut: ke-empat titik CPT mempunyai nilai Cone Resistance Conus dari kedalaman 1 meter antara 19,78 -23,73 kg/cm2 dan pada kedalaman 4 meter bernilai 201,75 – 205,68 kg/cm2. Sedangkan nilai SPT pada kedalaman 1 meter antara 2 – 18 Blows/feet dan pada kedalaman 4 meter nilai N antara 29 – 45 Blows/feet. Uji laboratorium menunjukkan sifat tanah lunak tanah tersebut berwarna, dan batas Atterberg (LL dan PL) makin membesar.

Abstract

Gorontalo is located at the macro and micro plate boundary, therefore it is located in an active seismotectonic region. This study aims to analyze earthquake damage level in Gorontalo based on seismicity and peak ground acceleration. The data used is obtained from the USGS. Data is made into a database and plotted onto a geological map. Calculation of peak ground acceleration is obtained using the Kawashumi formula. The results of this study indicate that Gorontalo is included in the slight to moderate earthquake damage level because it is dominated by shallow to intermediate earthquakes depth, light to moderate earthquake magnitude, and have a peak ground acceleration 1,462 - 99,714 gal.

Abstract

South Sulawesi was one of the first regions in Indonesia to implement the Large-Scale Social Restriction (LSSR) policy, which runs from April 24 to May 22, 2020, and is one of the non-pharmaceutical strategies used to encourage people to stay at home more in order to suppress the spread of the Covid-19 virus. The purpose of this study is to determine the impact of the LSSR policy on the behavior of people in South Sulawesi who stay silent in their homes, as well as how long the impact will last. The data used is big data in the form of the Google Mobility Report, specifically community mobility data in the form of a percentage change in the number of visits (towards the baseline) for places classified as residential areas measured daily from March 20 to May 22, 2020. The intervention ARIMA model (1,0,0) with the intervention order b=0, r=0, s=8 shows a significant impact from the implementation of LSSR in South Sulawesi using the univariate ARIMA (Autoregressive Integrated Moving Average) statistical analysis method. This is because of contradictory policies that encourage people to begin activities outside the home. The implementation of this policy, which was followed by the beginning of people leaving their homes in May 2020, also had an impact on rising prices due to decreased distribution of goods/services, resulting in scarcity. The study concludes that the LSSR policy has a significant effect on the behavior of people in South Sulawesi staying silent in their homes from its implementation until eight days later.

Abstract

Ground water is stored in layers called aquifers. These aquifers can be found in coastal plains, foothills, inter-mountain valleys, alluvial plains and karst topographic areas. The village of Buntu sugi, located in the foothill area in the form of alluvial plains and a little karst topography in the north. Buntu Sugi Village has four ground water sources in the form of springs. The four springs are Bubun Salle, Bubu Sudu, Bubun Matua, and Wailandan. All these springs are used by the community for daily living needs for cooking and for drinking water and used for agriculture. The condition of water resources in Buntu Sugi Urban Village is decreasing quantity and quantity is smaller flow rates in the dry season and a higher turbidity level in the rainy season. The efforts made in this community service are to educate the community on how to conserve springs or ground water and how to process polluted ground water so that it is suitable for use. Furthermore, training will be given to the appropriate technology community that can be used in the process of processing and purifying polluted water. The training on making Biopori Infiltration Holes and making water purification equipment has given the ability for participants. ---  Air tanah tersimpan dalam lapisan yang disebut akuifer. Akuifer tersebut dapat dijumpai pada dataran pantai, daerah kaki gunung, lembah antar pegunungan, dataran aluvial dan daerah topografi karst. Kelurahan Buntu sugi yang berada di daerah kaki gunung berupa dataran alluvial dan sedikit topografi karst di bagian utara. Wilayah Kelurahan Buntu Sugi terdapat empat sumber air tanah berupa mata air yaitu Bubun Salle, Bubun Sudu, Bubun Matua, dan Wailandan. Seluruh mata air tersebut digunakan masyarakat untuk keperluan hidup sehari-hari untuk memasak, untuk air minum dan kebutuhan pertanian. Penurunan kuantitas dan kuantitas ditandai dengan debit aliran yang semakin kecil pada musim kemarau dan melimpah pada musim hujan dengan tingkat kekeruhan yang semakin tinggi. Upaya yang dilakukan dalam pengabdian masyarakat ini adalah melakukan penyuluhan kepada masyarakat bagaimana melestarikan mata air atau air tanah dan bagaimana memproses air tanah yang tercemar sehingga layak digunakan. Tujuan pengabdian untuk melakukan edukasi kepada masyarakat pentingnya konservasi air tanah dan bagaimana teknologi konservasi air tanah dan pelatihan kepada masyarakat teknologi tepat guna (TTG) yang dapat digunakan dalam proses pengolahan dan penjernihan air yang tercemar.  Pelatihan pembuatan Lubang Resapan Biopori (LRB) dan pembuatan alat penjernihan air telah memberikan keterampilan kepada peserta untuk membuat resapan air dan alat penjernihan air.

Abstract

Diabetes mellitus (DM) is one of the chronic and deadly diseases that are widely observed in various countries today. This disease continues and is increasing to a very alarming stage. This study aims to identify and see the relationship between factors that influence DM disease. The method used in this research is C4.5 algorithm which is one of the algorithms used to make predictive classifications. Classification is one of the processes in data mining that aims to find patterns in relatively large data that use the representations in the form of decision trees. This method is applied to data from medical records of patients with DM in 2014-2018 taken from the Hasanuddin University Teaching Hospital. The results obtained indicate that there are four factors that influence the prediction of a patient's DM status namely; Fasting Blood Glucose (GDP), LDL Cholesterol, Triglycerides, and Body Weight.
