Abstract

Pada penelitian ini telah dilakukan perancangan alat ukur berbasis sensor yang terintegrasi untuk pengukuran karakteristik tanah. Parameter yang diukur oleh alat ukur ini yaitu konduktivitas, pH, Kelembaban, dan temperatur tanah. Parameter yang diukur tersebut merupakan karakteristik tanah yang penting untuk menentukan tingkat kerusakan lahan gambut pasca kebakaran. Sistem alat ukur ini terbagi ke dalam tiga bagian yaitu bagian tempat sampel, bagian sensor yang akan mendeteksi parameter fisis dari sampel, dan kotak rangkaian. Sistem alat ukur ini juga terdiri dari perangkat keras dan perangkat lunak. Perangkat keras terdiri dari sensor EC10 keluaran RS485, sensor pH, mikrokontroler Arduino Mega2560, dan monitor LCD. Sedangkan perangkat lunak dibuat menggunakan program arduino IDE. Tahap pengujian meliputi menyelidiki fungsi transfer dan sensitivitas dari sensor. Hasil pengujian dari penelitian ini yaitu tingkat sensisitifitas sensor yang digunakan untuk parameter pH, temperatur, konduktivitas, dan kelembaban masing-masing adalah 0,0139 mV/pH, 4,5157 mV/0C, 1,1607 mV/ μ S/cm, dan 2,1017 mV/%. Hasil penelitian alat ukur tanah dapat bekerja baik dan alat ini memiliki tingkat akurasi sebesar 99,9%. Penelitian ini harapannya dapat menghasilkan alat ukur yang berfungsi membantu pihak terkait untuk mengidentifikasi kerusakan lahan gambut dengan mudah dan akurat.

Abstract

Based on emerging DHF cases occur various solutions for the prevention and control of the transmission of dengue, one of them is to create a mathematical model. The Mathematical model that was developed is a SIR (Susceptible (S), Infected (I) and recovered (R)),, where the rate of displacement of latent mosquitoes become infected mosquito is assumed constant and healthy mosquito eggs produced by infected mosquitoes and susceptible mosquitoes, while the mosquito is infected eggs produced only by infected mosquitoes. In the SIR model, an analysis is performed to assess the stability of the equilibrium point and numerical simulations. Numeric simulation was introduced to show the stability at the equilibrium state considered basic reproduction number ℛ0 .There are two equilibrium points. The first equilibrium point is a the disease-free equilibrium which is stable, ℛ0<1. The second equilibrium point is called an endemic equilibrium, which is stable, ℛ0>1. The numerical simulations show that increasing mosquitoes mortality rate makes ℛ0, infected human, latent mosquito, infected mosquito, infected egg are decrease, so as to help suppress the spread of the disease in the population.

Abstract

Telah dilakukan pengujian nilai konduktivitas dengan menggunakan alat Impedansi Analizer, dimana nilai impedansi dijadikan sebagai parameter penentuan perubahan konduktivitas akibat penambahan pupuk NPK (tambahan unsur hara tanah). Sampel yang digunakan adalah jenis tanah inseptisol dengan 5 variasi jenis tanah, sampel diambil dari 5 titit berebeda pada lahan perkebunan daerah kampus Universitas Jambi.Tahap awal pengujian dilakukan pengukuran nilai impedansi pada H-1 (hari pertama) dengan penambahan pupuk NPK sebesar 0%, 1%, 3%, 5% dan 7% terhadap masing-masing sampel, untuk memastikan nilai konduktivitas hanya dipengaruhi unsur hara NPK maka kelembaban di berikan konstant pada kisaran 40%-45%. Setelah pengambilan data tahap awal sampel dibiarkan dan ditutup dalam pelastik agar terjadi penguraian pupuk pada tanah, penguraian dilakukan secara Anaerobdengan estimasi penguraian 12 hari, setelah hari ke- 12 dilakukan kembali pengujian nilai impedansi terhadap masing-masing sampel. Hasil pengukuran nilai konduktivitas mengalami kenaikan terhadap penambahan pupuk dan setelah terjadi penguraian, hal ini dapat dilihat dengan berkurangnya nilai impedansi. Secara kuantitatif semua jenis sampel tanah mempunya hubungan linier dengan nilai regresi >99% terhadap penambahan pupuk dan penguraian unsur hara, untuk itu penelitian ini akan menjadi dasar pemodelan alat kesuburan tanah dengan parameter nilai konduktivitas.

Abstract

ABSTRACT Background: The population of Sekernan Subdistrict in 2020 is 45.207 people, with the development of an increasing population, it will affect the increase in the amount of waste scattered in illegal locations, so it is increasingly necessary to improve the availability of Temporary Waste Shelters. Objective: The purpose of this study was to analyze and to map temporary waste shelters in Sekernan Subdistrict, Muaro Jambi Regency.. Method: Descriptive research with the results of mapping temporary waste shelters based on Global Positioning System and Geographic Information System, data using total sampling in Sekernan Subdistrict. The data analysis used is descriptive analysis and is presented in the form of output in the form of maps and tabulation of data. Results: The results showed that in Sekernan Subdistrict there are 24 illegal temporary waste shelters, more than half with a waste volume of 0.1-3.5 m3 (54.17%), most of them are located near neighborhood roads (83.33%), and most of them are located at high population density levels (75%). Furthermore, according to SNI 19-2454-2002, the minimum standard is 180 legal temporary waste shelters in Sekernan District. Conclution: The minimum standard for temporary waste shelters in the Sekernan Subdistrict is 180 points, which can be mapped based on population density figures and qualified land availability. Keywords: analysis, mapping, temporary waste shelters

Abstract

Debt is a transaction in which two people voluntarily give money to another person and then return it to them in the same way. This study aims to determine how Ibnu Katsir views the concept of accounts payable and receivable from an Islamic economic perspective. Although we know that debts and receivables are permitted, Islam advises its followers to avoid debts as much as possible, regardless of whether they can afford to buy something with cash or not when they are in limited economic conditions. Because debt is always a heavy burden and threatens morality. Rasulullah saw. once refused to pray for the body of someone who owed a lot of debt to his family and did not have the means to pay it. As explained in the Koran, recording or writing is the first step in debt and receivable transactions. This research uses library research methods with an interpretive science approach using the tahlili method. The results of this research show that people who owe money are obliged to tell the clerk about the debt they admit because they are worried that there will be fraud against those who owe it. If it is a buying and selling transaction, it is permissible not to record or write down the transaction. Furthermore, there is a need for fair witnesses. In terms of testimony, Ibnu Katsir stated that being a witness is fardlu kifayah or not mandatory for the person concerned unless there is another person who can replace his position
