Abstract

Irrigation is a supporting infrastructure for water distribution in agriculture. Its role is vital, especially for agricultural areas which are not rain-fed, meaning that to irrigate agricultural areas the irrigation infrastructure is needed. It is important for all parties involved in agriculture and irrigation management institutions to find out and ensure the condition and performance of an irrigation network, whether its function is still as planned or even vice versa. So far, the performance evaluation of irrigation networks is still carried out conventionally and only reaches a form of Maintenance Operation report, not specific to its performance. So based on these conditions, this research will build an expert system that can be used to assess the performance of irrigation networks. The design begins by determining the logic of assessment that will be used as a way of thinking from the expert system that will be built. The indicators used by the system to assess irrigation performance are as stated in the regulation of the Ministry of Public Works and Public Housing No. 12 of 2015. After designing the expert system, the next step is to simulate it using the data available in the operation and maintenance reports of some irrigation networks that are used as samples. Then the simulation results are analyzed so that it can be known whether the system can work as planned or not. The system simulation results show a mismatch between the two indicators namely the performance of infrastructure and water services. While other assessment indicators have logical results.

Abstract

Planning for water needs for irrigation areas is carried out to determine the water needs for plants to grow and develop. The source of water obtained for meeting water needs comes from the Walahar Dam. The results of water demand planning can also be used to simulate cropping patterns. Cropping patterns are very helpful for farmers in determining effective and efficient planting times. Calculation of plant water needs is processed from climatological data and rainfall data, the results of which are demand discharge. Based on the results of the calculation of water requirements for plants, the average discharge requirement is 0.65 m3/second – 9.59 m3/second, while the available water or available discharge in Walahar Weir is 183.90 m3/second. So it can be concluded that the available water in Walahar Weir can meet the water needs of plants. Keywords: Discharge, Climatological Data, Rainfall Data, Plant Water Demand Planning

Abstract

The phenomenon of the teaching and learning process of students with intellectual disabilities is quite interesting, because of the development of a child who shows limitations in intellectual functioning and social adaptation. Students with intellectual disabilities have below-average intelligence and difficulty learning, understanding, and solving problems, especially in communication. The purpose of this study is to find out how the communication strategies used by teachers in teaching students with intellectual disabilities at the elementary, junior high, and high school levels at the SLB B / C Budi Lestari Education Foundation, Sukatani Depok. This research uses Charles Berger's theory of Planning and the theory of Symbolic Interactionism by George Herbert Mead. This research uses qualitative methods and constructivist paradigms. The results of this study show that teacher communication strategies in teaching students with intellectual disabilities both elementary, junior high, and high school at the SLB B / C Budi Lestari Sukatani Education Foundation, Depok are using media assistance and combining verbal and non-verbal forms of communication in the learning process. Teachers apply communication strategies, namely to secure understanding, to establish acceptance, and to motivate action. The process of implementing strategies is carried out by interacting using the help of media such as images, computers, body language, and facial expressions.

Abstract

Artikel ini mengungkap penafsiran Syaikh Nawawi al-Bantani pada surat al-Nisa ayat 86 tentang kebolehan salam kepada non muslim. Ungensi dari artikel ini adalah bantahan terhadap larangan salam kepada non muslim. Lewat artikel ini penulis hendak mengungkap penafsiran ulama-ulama yang sejalan dengan Syaikh Nawawi al-Bantani dalam menfasiran surat al-Nisa ayat 86. Melalui analisis terhadap ayat al-Qur’an, diketumakan surat al-Nisa ayat 70, bahwa manusia (bani adam) dimuliakan Tuhan. Kata manusia (Bani Adam) dalam al-Qur’an meng-isyaratkan tidak dibatasi agama, Islam atau bukan Islam. Dengan demikian batasan salam hanya kepada muslim yang ditafsirkan sebagain ulama didasarkan pada surat al-Nisa ayat 86, terbantahkan oleh surat al-Nisa ayat 70. Hal yang menarik lainnya, dalam artikel ini akan memetakan para mufasir dalam menafsirkan surat al-Nisa, baik kubu yang memahmi larangan salam kepada non muslim, maupun yang membolehkannya.
