Penelitian ini dilaksanakan di Jorong Pincuran Tujuah, Nagari Batipuh Baruah, Kecamatan Batipuh, Kabupaten Tanah Datar. Tujuan penelitian adalah (1) menganalisis risiko produksi yang terjadi pada kopi robusta di Jorong Pincuran Tujuah, (2) mendeskripsikan manajemen risiko yang dilakukan oleh petani pada produksi kopi robusta di Jorong Pincuran Tujuah. Penelitian ini menggunakan metode survei dengan analisis data deskriptif kualitatif dan analisis kualitatif. Hasil penelitian mengungkapkan bahwa sumber risiko produksi kopi robusta di Jorong Pincuran Tujuah yaitu hama monyet, hama musang, hama kelalawar, hama penggerek buah kopi, penyakit karat daun, penyakit bercak daun, kurang efektif dalam melakukan penyiangan, cuaca dan petani yang tidak melakukan sortasi. Berdasarkan analisis tingkat risiko produksi dengan menggunkan pemetaan risiko, risiko pada kuadran I merupakan tingkat risiko paling tinggi dengan frekuensi yang tinggi dan dampak yang juga tinggi bagi petani. Sumber risiko pada kuadran I yaitu hama penggerek buah kopi, kurang dalam penyiangan dan cuaca saat penjemuran. Strategi pengelolaan risiko yang dilakukan petani kopi Robusta di Jorong Pincuran Tujuah adalah stategi preventif dengan melakukan penyiangan dan berburu. Kata kunci: risiko produksi, sumber risiko, tingkat risiko, manajemen risiko.

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.

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

Sampah menjadi masalah yang sangat penting menjadi perhatian saat ini. Ketika jumlah sampah semakin hari semakin meningkat akan mengganggu kesehatan dan lingkungan. Untuk itu mengelola TPA Sampah menjadi objek wisata yang bernuansa edukatif sangat menarik untuk diteliti. Penelitian ini ingin mendeskripsikan kampanye Dinas Lingkungan Hidup dalam membangun TPA ( Tempat Pembuangan Akhir Sampah menjadi obyek wisata bernuansa edukatif.Metode penelitiannya menggunakan metode kualitatif. Teori yang digunakan S-O R. Hasilnya upaya kampanye yng dilakukan dinas lingkungan hidup sudah sangat baik dengan menjadikan wisata bernuansa edukatif seperti cara pengolahan sampah, membuaat pupuk dari bahan sampah (kompos) mengetahui gas methan dan melihat dari dekat cara belajar daur ulang dari bahan sampah.

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

Critical thinking, creativity, and problem-solving skills are critical for vocational schools graduates to enter the workforce in the industrial era 4.0. This study aims to find a learning strategy that can develop these three skills. The study was carried out at SMK X Mojokerto in the Automotive Technology Program in the academic year of 2017/2018. Data were collected using an observation sheet validated by three experts and tested with inter-rater reliability. The data analysis method is t-test. The results of data analysis showed that the Contextual Project Based Learning (CPjBL) was generally effective to improve critical thinking, creativity, and problem-solving skills. Detailed observation included each of these aspects. The findings showed that the implementation of contextualized learning problems could improve the aspect of originality and problem understanding skills, which was usually difficult to improve. On the other hand, CPjBL was not effective in developing the ability of analysis in critical thinking and look-back in problem-solving skills.
