Abstract

Munculnya kolam air panas di Sungai Medang Kerinci merupakan salah satu indikasi adanya zona permeabel. Struktur geologi berupa patahan atau zona rekahan adalah salah satu indikasi zona permeabel. Zona rekahan merupakan salah satu indikasi adanya zona outflow. Untuk memperkirakan mata air panas yang terdapat di Sungai Medang termasuk dalam zona outflow diperlukan penyelidikan dengan menggunakan metode geolistrik tahanan jenis dengan konfigurasi wenner-schlumberger dan schlumberger dengan 3 lintasan yang terdiri dari 2 lintasan sounding dan 1 lintasan mapping. Pengolahan data dilakukan dengan software IPI2WIN dan RES2DINV. Berdasarkan pengolahan dan analisa data diperoleh bahwa terdapat rekahan pada kedalaman 0-17,8 meter dengan harga resistivitas yang relatif keci yang terdapat pada jarak 130 – 170 meter.

Abstract

Pengukuran kadar kafein saat ini dibutuhkan agar penggunaan/konsumsi kopi sesui dengan dosis yang dibutuhkan, akan tetapi, sulitnya karakterisasi dan uji kimia dalam penentuan kadar kafein menjadi hambatan untuk mengetahui dosis kafein secara cepat dan tepat. Pada penelitian ini telah dilakukan karakterisasi sensor warna TC3200 sebagai studi awal rangkaian pembuatan alat ukur kafein berbasis sensor. Sampel yang digunakan adalah kopi Liberika, Arabika dan Robusta yang berasal dari Provinsi Jambi. Preparasi sampel dilakukan dengan proses roasting pada suhu 180OC dan pada saat proses berjalan pengambilan sampel secara real time pada (t= 38-45s), hasil preparasi sampel dilakukan uji UV-Vis untuk mengetahui konsentrasi  kandungan kadar kafein. Selanjutnya karakterisasi sensor warna TC3200 dilakukan untuk mengetahui nilai RGB (Red, Green, Blue) dari masing – masing sampel kopi. Hasil penelitian didapatkan nilai kadar kafein dari pengukuran UV-Vis yang akan menjadi database sensor, dan hasil karakterisasi sensor warna TC3200 pada kopi Liberika, Arabika dan Robusta secara kuantitatif didapatkan tingkat kevalidan data masing – masing 80%, 60% dan 70% dan analisis kualitatif bahwa sensor dapat digunakan untuk menetukan kadar kafein pada kopi dengan tingkat kematangan atau waktu roasting kopi yang berbeda.

Abstract

Tujuan penelitian ini adalah untuk menguji apakah terdapat pengaruh signifikan model Learning Cycle 7E terhadap kemampuan pemecahan masalah menurut John Dewey. Populasi penelitian ini adalah seluruh siswa kelasVIII SMP Negeri 12 Kendari. Teknik pengambilan sampel menggunakan simple random sampling sehingga terpilih 2 kelas sebagai sampel penelitian. Kelas VIII1 sebagai kelas kontrol menerapkan model pembelajaran langsung dan kelas VIII2 kelas eksperimen menerapkan model learning cycle 7E. Desain penelitian menggunakan posttest-only control group design. Data penelitian dikumpulkan melalui tes dan lembar observasi. Analisis data menggunakan metode statistik deskriptif dan inferensial. Nilai rata-rata kemampuan pemecahan masalah matematis siawa menurut John Dewey yang diajar dengan menerapkan model learning cycle 7E lebih tinggi dari nilai rata-rata kemampuan pemecahan masalah matematis siswa menurut John Dewey yang diajar dengan menerapkan model pembelajaran langsung. Hasil penelitian menunjukkan bahwa terdapat pengaruh signifikan model Learning Cycle 7E terhadap kemampuan pemecahan masalah menurut John Dewey pada siswa SMP.

Abstract

A study comparing the performance of machine learning algorithms to predict soil nutrient values based on soil impedance has been conducted. The algorithm models used include Linear Model, K-Nearest Neighbors (K-NN) with n-neighbors 3, 18, 21, 24, 27, and 30, Decision Tree with max depth 3, and Random Forest with n-estimators 6 and 21. During the training phase, 10 model variations with the best performance were found, including Linear Model, K-NN (n-neighbors), Decision Tree (max depth 3), and Random Forest (n-estimators 6 and 21). In the testing phase, Random Forest (n-estimator 21) showed the best performance with MAE = 0.15%, MSE = 0.09%, RMSE = 0.31%, and accuracy = 99.85%. Regression analysis indicated an R-squared value of 0.924, indicating that most of the variations in soil impedance values can be explained by variations in soil nutrient values. A regression value approaching 1 indicates that the regression model used has a very good ability to explain the variations observed in the data. This indicates that most of the variations in the dependent variable (the variable being predicted, which is the nutrient values) can be explained by the independent variable (the predictor variable, which is the soil impedance values) in the model. Correlation analysis resulted in a strong negative correlation between impedance and Al, Fe, K, Ca, Zn, Ni, Ta, V, Cr, and Mn (values -0.81 to -0.99), while a positive correlation occurred with Mg, Si, S, Cl, Ti, Zr, and Ga (values 0.65 to 0.99). This indicates that an increase in impedance values is generally followed by an increase in nutrient values.

Abstract

Background: Evaluation of cross-sectoral control of refillable drinking water depot is a strategic role in protecting consumers to obtain standardized drinking water quality. Objective: The purpose of this study was to evaluate the factors in the control and management of refillable drinking water depot in the working area of the Muaro Jambi District Health Center. Methods: The method used was a descriptive qualitative approach, which is to understand the phenomenon of the research subject holistically. Results: The results showed that the evaluation conducted by the health office was not optimal, most of the refillable drinking water depots in the Puskesmas working area had not been inspected. This is influenced by limited human resources in monitoring and evaluating each refillable drinking water depot, lack of socialization and education to refillable drinking water depot businesses and the community regarding the importance of consuming quality-assured drinking water, and especially the lack of awareness of refillable drinking water depot businesses to pro-actively meet drinking water quality standards. Conclusion: The lack of optimal cross-sectoral control of refillable drinking water depots is influenced by human resources and socialization and education programs, along with community awareness. It is expected that there will be more intensive integration between the health center, health office, and village officials who play a role in monitoring and evaluating the management of refillable drinking water depot.

Abstract

Fly density is an indicator of environmental sanitation assessment. Fly density is influenced by waste management, the National Waste Management Information System (SIPSN) shows that waste generation in Jambi City reaches 159,688.01 tons/year. The aim of this research is to determine factors related to the level of fly density in Temporary Waste Storage Sites (TPSS) in Telanaipura District, Jambi City 2023. This research is a quantitative research with a cross sectional method research design. This research was conducted in the Telanaipura District community with a sample of 94 people. Data analysis was carried out using univariate and bivariate methods using correlation tests. The results of this study indicate that knowledge (p=0.027), action (p=0.029), monitoring (p=0.017), sorting (p=0.016), collection (p=0.027), and transportation (p=0.026) have relationship with the level of fly density, while attitude (p=0.245) had no relationship with the level of fly density. Knowledge, action, monitoring, sorting, collection and transportation are factors related to the level of fly density in temporary waste storage sites in Telanaipura District. It is hoped that the public will pay attention to managing household waste properly.
