    Nickel Oxide (NiO) have widely applied in industrial and automotive to forming oxide layer on the substrate due to it have high thermal stability and corrosion resistant. However, NiO was not directly diffused to the substrate via co-precipitation, spray-pyrolysis and sol-gel methods. Therefore, NiO-electroplating was performed in coating FeCrAl substrate by γ-Al2O3 powder. This method was conducted using various time of 15, 30, 45, 60 and 75 minutes, a current of DC power supply is 1.28A and sulphamate type solution. From the data shows that smallest surface roughness (Ra) of NiO-electroplating (EL) samples located at EL 30 min sample for 0.69 µm. Ra of raw material was lower than coated samples due to it performed by coating activity on the substrate. It supported by coating thickness analysis that treated samples has a higher coating thickness up to 11.3 µm. EDS analysis observed some elements on coated and uncoated samples such as Carbon (C) of 4.62-20.67%, Oxygen (O) of 6.16-19.62%, Nickel (Ni) of 6.76-25.14%, Iron (Fe) of 23.96-48.53%, Sodium (Na) of 2.21-9.95%, Chromium (Cr) of 7.97-15.59% and Aluminum (Al) of 2.17-3.12%. Those elements promote to develop a protective oxide layer on FeCrAl at a high temperature of 1000 0C.

    Drugs are often associated with intoxicants. In the context of fiqih drugs usually dikiaskan to prohibition of wine. However, in line with the development of contemporary medical science, the works of the new fiqh also mention and emphasize that the effects of damage also have its own influence in relation to drug law. This study aims to explore and analyze the trends of contemporary jurisprudence works in explaining their backs in relating the status of Sharia law values to drug abuse. This study uses qualitative methods. The data obtained from these works were analyzed and made comparisons. A number of 10 contemporary works that discuss drug law and the reasons for its prohibition have been used in this study. The study concluded that the works agreed that drug abuse is haram according to the Shari'a. All activities related to drug abuse such as planting, processing, owning, buying or selling permits used to cooperate with its misuse are haram. Likewise, in terms of its proofing proposition, all works tend to see it is based on the kias to the wine based on the argument that drugs are potentially intoxicating. The works only mention the destructive aspect without emphasizing it as an important basis for the prohibition of drug abuse. This is certainly not in accordance with the reality of the threat of drugs that not only grab the function of the intellect alone, even damaging the five-five main objectives of Islamic law, namely religion, life, intellect, descent and wealth. Hence the affirmation of the restrictive section needs to be emphasized in an effort to ensure fair drug abuse is prevented and handled more seriously in order to ensure the well-being of the ummah is maintained.

    Human activity recognition (HAR) with daily activities have become leading problems in human physical analysis. HAR with wide application in several areas of human physical analysis were increased along with several machine learning methods. This topic such as fall detection, medical rehabilitation or other smart appliance in physical analysis application has increase degree of life. Smart wearable devices with inertial sensor accelerometer and gyroscope were popular sensor for physical analysis. The previous research used this sensor with a various position in the human body part. Activities can classify in three class, static activity (SA), transition activity (TA), and dynamic activity (DA). Activity from complexity in activities can be separated in low and high complexity based on daily activity. Daily activity pattern has the same shape and patterns with gathering sensor. Dataset used in this paper have acquired from 30 volunteers. Seven basic machine learning algorithm Logistic Regression, Support Vector Machine, Decision Tree, Random Forest, Gradient Boosted and K-Nearest Neighbor. Confusion activities were solved with a simple linear method. The purposed method Logistic Regression achieves 98% accuracy same as SVM with linear kernel, with same result hyperparameter tuning for both methods have the same accuracy. LR and SVC its better used in SA and DA without TA in each recognizing.

    Penelitian ini bertujuan untuk mengetahui mutu protein dendeng ikan hiu (Chiloscyllium sp.) yang dikeringkan dengan menggunakan tiga jenis metode pengeringan yang berbeda, yaitu pengeringan dengan sinar matahari, oven udara panas (60°C) dan oven vakum (60°C). Sebelum dikeringkan, irisan daging ikan (ukuran 4 cm x 12 cm x 3 mm) direndam dalam larutan bumbu dan dikeringkan sehingga kandungan airnya berkisar antara 23-25%. Analisis dilakukan terhadap kandungan asam amino bahan baku dan dendeng hiu, dan nilai asam amino digunakan untuk menghitung skor kimia, skor asam amino, dan indeks asam amino. Hasil penelitian menunjukkan bahwa pada daging ikan hiu segar, skor kimia, skor asam amino, dan indeks asam amino esensial lebih tinggi dibandingkan dengan dendeng ikan hiu dengan berbagai cara pengeringan. Secara umum, pengeringan menyebabkan terjadinya penurunan mutu protein dendeng ikan hiu. Skor kimia, skor asam amino, dan indeks asam amino esensial daging ikan hiu segar berturut-turut adalah 65,93; 100,49; dan 89,13; pengeringan oven 56,48; 82,59; dan 75,86; pengeringan sinar matahari 51,15; 61,55; dan 79,43; dan pengeringan oven vakum 51,86; 62,41; dan 72,44. Hasil penelitian ini menunjukkan bahwa dendeng ikan hiu dengan pengeringan oven udara panas memiliki nilai skor kimia dan skor asam amino lebih tinggi, sedangkan dendeng dengan pengeringan sinar matahari memiliki indeks asam amino esensial lebih tinggi dari sampel lain

    People encounter many changes in the first year of college. It was related to adjustment’s problems, which was a serious problem that must be faced when entered college. Adaptation to new environment can make individual experienced stress. The various studies have shown that medical students experienced stress more higher than non-medical program students. Students who are experiencing extreme stress or depressed require serious attention cause it can have an adverse effect on learning process, achievement and even intent to suicide. This research involved 49 medical students. It took to determine the correlation between level of adjustment to academic demands and stress degree on new students in Faculty of Medicine, Islamic University of North Sumatra, T.A 2016-2017. Student Adaptation to College Questionnaire (SACQ) and Kessler Psychological Distress Scale (K10 Test) were used to collect relevant data on adjustment rates and stress levels. Data were analyzed by using Spearman correlation test. The results showed that there was a significant negative correlation between adjustment rates to academic demands with stress level on new students with p value of 0.001 (p <0.05) and r value of -0.697.

    Adaptive neuro-fuzzy inference system (ANFIS) is a prospective approach in modeling weather parameters based on learning from historical data used. This study presented the comparison of tropospheric precipitable water vapor (PWV) between ANFIS and Global Positioning System (GPS) for areas in Pekan, Pahang, Malaysia. The PWV value was estimated with the ANFIS model with the surface meteorological data as inputs. The accuracy of PWV from ANFIS has been validated with PWV from GPS measurements for the period of 2010. The result showed that the ANFIS PWV has a similar trend with the GPS PWV (r = 0.999 at the 99% confidence level) and found a difference of 0.024%. The PWV from ANFIS was calculated 0.035% higher compared to GPS PWV and found a similar character in two seasonal monsoons. This indicates that the PWV obtained with ANFIS model agreed very well with GPS measurements and it can be implemented to monitor atmospheric variability as well as climate change studies in the absence of GPS data

    Takaful operators are expected by the policyholders to act beyond the role of traditional insurance companies that only offer Shariah-compliant protection services. They are expected to be commercially viable. One of the ways to be commercially viable is takaful operators must be able to invest the policyholders' funds in the profitable investment avenues. Nevertheless, the critical issue before investing the funds is to develop products that are suitable with the takaful operators' investment strategy. This study employed a questionnaire survey to gather the feedback of fund managers from 11 takaful operators in Malaysia — all were the senior staffs of takaful operators in Malaysia were surveyed. The questionnaire is developed in the form of a Likert scale ranging from 1 to 5 as the research instrument. By Delphi technique, the draft of the questionnaire was sent to a panel of experts for review, was adopted, and their feedback reflected in the final questionnaire. The experts were a shariah advisor, a corporate finance manager, and a senior executive at the central bank. Findings indicate that policyholders' expectations on their investments are met and the products so far compatible with takaful operators' investment strategies.
