Abstract

Dalam perancangan penelitian ini dibuat robot yang bisa mengenali benda berdasarkan warna dengan menggunakan mikrokontroler berbasis arduino uno.Robot akan mengelompokkan jenis ban yang sama secara otomatis Robot ini mendeteksi 3 macam warna yaitu merah, hijau, warna biru yang terdeteksi dengan menggunakan Sensor warna mencakup frekuensi keluaran, frekuensi frekuensi yang dihasilkan tergantung pada kepekaan cahaya. Sebagai pusat kendali menggunakan bahasac. Sensor warna yang digunakan untuk membaca RGB adalah sensor TCS3200. Sensor ini memiliki jarak optimal dan nilai cahaya untuk memaksimalkan pembacaan nilai RGB, yaitu jarak 8 cm dari sensor warna ke objek objek. Sedangkan untuk mengukur bentuk dan tinggi badan menggunakan sensor ultrasonik. Sensor ultrasonik akan membaca objek dengan ketinggian sekitar 8 cm.untuk mendapatkan kontrol logika fuzzy nialai yang terlihat dari ketinggian benda dan penempatan benda. Dalam desain ini memnggunakan logika logika mamdani untuk inputnya yaitu warna dan jarak RGB, jadi untuk outputnya adalah warna (merah, hijau, biru). Jadi dalam penyimpanan data yang menggunakan data base phpmyadmin pengganti data bermanfaat untuk dilaporkan ke manajemen. Berdasarkan data yang diperoleh dapat disimpulkan bahwa Lengan robot baik digunakan untuk membantu pekerja bekerja lebih praktis sehingga tidak memakan waktu lama dalam memisahkan dan menggerakkan ban

Abstract

Risiko selalu ada dalam setiap proses pekerjaan proyek dan apabila risiko ini tidak diantisipasi dengan benar dan tepat oleh pihak penyedia proyek, maka dapat menghambat pelaksanaan proyek, atau bahkan dapat mengakibatkan terjadinya kerugian. Maksud dan tujuan penelitian adalah mengetahui faktor-faktor risiko  paling dominan dan melakukan mitigasi risiko yang ada pada proyek Gedung K3 Surabaya. Teknik pengumpulan data menggunakan kuisioner dan wawancara melalui instrumen skala likert, analisa data menggunakan analisis bantuan aplikasi SPSS 24 dan  penelitian ini menggunakan metode probability impact matrix. Hasil penelitian menemukan 2 faktor dominan yaitu : (1) Kesalahan perencanaan manajemen, (2) Ketersediaan material. Risiko tersebut termasuk dalam kategori risiko yang harus dicegah dengan respon risiko agar tidak terjadi keparahan. Kata kunci : Risiko, mitigasi, Lumpsum, Kontrak.

Abstract

Diatoms are the largest phytoplankton group and as the primary producer in marine waters. This research was conducted in September 2016 around Cawan Island of In-dragiri Hilir Regency of Riau Province. The aim of this research was to determine the structure of epiphytic diatom community on the midrib of Nypa fruticans and to deter-mine water quality as well as to see the relationship of epiphytic diatoms abundance with water quality. The survey method was applied in this research and sampling loca-tion determined by purposive sampling. Measurement of water quality was done by in situ and ex situ which consist of biology, physics and chemical parameters. Nitrate concentrations in waters ranged from 0,0139 to 0,0639 mg/l and phosphate concentra-tions ranged from 0,1342 to 0,2345 mg/l. The epiphytic diatoms on the midrib of Nypa fruticans in Cawan Island consist of 18 genera of diatoms, the average value of abun-dance ranged from 7.385 to 23.042 individual/cm2, the mean value of diversity index ranged from 1,41 to 2,05.The dominance index value ranged from 0,27 to 0,52 and the uniformity index value ranged from 0,58 to 0,91. Meanwhile, the correlation of diatom abundance with concentration of nitrate was 0,21 (weak relationship) and correlation of diatomic abundance with phosphate concentration was 0,11 (very weak relation-ship). Based on the result of epiphytic diatom calculation on the midrib of Nypa fruti-cans can be concluded that the waters in Cawan Island was in medium contaminated condition.

Abstract

This article examines the transformation policy of IAIN to UIN by the Directorate of Islamic Religious Higher Education (Dit. Diktis) of the Directorate General of Islamic Education (Ditjen Pendis) of the Ministry of Religious Affairs (Kemenag) of the Republic of Indonesia. Specifically, this article describes in depth the background and policy objectives of Dit. Diktis in the transformation of IAIN to UIN; and the implementation of the transformation policy of IAIN to UIN at Dit. Diktis of the Ministry of Religious Affairs from 2002 to 2017. This study used a qualitative method with the type of case study research. Data collection techniques consist of observation method, in-depth interview, and documentation. While data analysis techniques include: data reduction, data presentation, verification, and concluding. Checking the validity of the data consists of credibility, transferability, dependability, and confirmability. The results of this study found that the basic policy formulation for the transformation of IAIN to UIN occurred in different contexts and situations for three periods. They are: 1) the first period, 2002-2005 (6 UIN), 2) the second period, 2013-2015 (5 UIN), and 3) The third period, 2017 (6 UIN).

Abstract

The role of middlemen in rural areas is often controversial, particularly because of the positive or negative roles they play in the farmer livelihood. This study aims to understand the farmers' perception of the role of middlemen in facilitating their farming system and to find out the socioeconomic factors that determine to what degree farmers attach themselves to middlemen. To get this information, we conducted a case study survey of 92 respondents from the subdistrict of Rasau Jaya, Kubu Raya, West Kalimantan, Indonesia. Approximately 95% of the farmers had a positive perception of the role of the middlemen, which was considered important in the farm produce marketing and also the transportation of both fertilizer and crops. Older farmers, farmers with a higher education level, and farmers with more vegetable commodities were less attached to the middleman in the marketing of their agricultural products. These farmers often changed the middleman to get a higher price. Conversely, farmers producing sweet maize and farmers with a higher income level were more attached to a middleman. A high level of engagement with a middleman is one of the farmer strategies to avoid marketing risks.
