Plant Characteristics for Green Wall Systems
No full textThis research is a preliminary study of planting ornamental plants with a green wall system. This study aims to provide an overview and information about the selection of types of plants that are suitable and commonly used in making green walls and arranging selected plants in green walls system. Green wall system which is often called vertical garden is a technique to plant ornamental plants, vegetables or other types of plants with a free design that considers various resources that allow plants to grow vertically. The advantages of green walls are efficient use of soil, beautifying the environment, adding location value, cleaning the air, lowering temperature, producing oxygen and providing fresh food that is close to the surrounding environment at home. Not all types of plants can be planted vertically. Easy-to-grow plants, short appearance and slow growth are common characteristics used for green walls. The special characters of the selected plants are determined based on the group of indoor or outdoor plants. Consideration of nutritional, light, water and plant requirements will determine the success of planting and the sustainability of vertical planting

To distinguish between pork oil and palm oil, we can use the characteristics of light absorbtion from the material. So, in this research we set a detection method using light intensity as the parameters. Equipment that we used are LDR sensors and red LED
No full textTo distinguish between pork oil and palm oil, we can use the characteristics of light absorbtion from the material. So, in this research we set a detection method using light intensity as the parameters. Equipment that we used are LDR sensors and red LED as the light source. Pork oil and palm oil were varied into two types of treatment, namely oil with no filtering and a single filtering. In this experiment we got that pork oil has higher light intensity than palm oil. It means that palm oil more absorb the light than pork oil. So, we conclude that light intensity can distinguish the type of oil. Further study is needed so we can develope more accurate and simple detection tool to determine the type of oil especially pork oil in order to give information about halal food for muslim

Cluster Analysis Using Hierarchic Method for Classification of District / City of North Kalimantan Province Based on Human Development Indicators (HDI)
No full textHDI is an important indicator in measuring the success of the development of the quality of human life in terms of education, health, and life worthiness. HDI in the province of North Kalimantan (Kaltara) has always experienced a significant increase. However, the increase is always below the national figure. This is due to the development that is not implemented evenly and is not on target. Cluster analysis is a multivariate method that has the aim of grouping, where a group has relatively the same characteristics (homogeneous), while between groups has different characteristics. This study showed that the best method in hierarchical cluster analysis is the ward\u27s method. Therefore, there were 4 clusters in the HDI in North Kalimantan province which included HDI with the high category, namely the city of Tarakan, then the HDI with the medium category, namely Malinau district then the HDI with the low category namely Bulungan district, then the HDI with the very low category namely Tanah Tidung district and Nunukan district

METODOLOGI SAINS MENURUT SEYYED HOSSEIN NASHR (STUDI ATAS KRISIS EKOLOGI)
No full textPemikiran tentang isu krisis ekologi menjadi salah satu perhatian berbagai kalangan akhir-akhir ini. Isu ini menjadi perbincangan dalam dalam kancah pemikiran di Barat dan Timur. Hal inipun tidak luput dari diskursus ilmuan muslim modern, salah satunya Syed Hussein Nashr. Ia merupakan intelektual Islam yang terkemuka dalam diskursus relasi Sains dan Agama. Namun perhatiaannya juga ia curahkan untuk membahas permasalahan-permasalah yang lain, salah satunya tentang isu ekologi. Pemikiran tokoh ini tentang ekologi berupa tawaran metodologi sains untuk mengatasi dan menanggani permasalahan ekologis perpektif Islam. Untuk itu ia menawarkan dua agenda yang harus yang harus dicermati dan dilaksananakan, yaitu merumuskan kembali nilai-nilai kearifan perenial Islam mengenai tatanan dan konsep tentang alam, hubungan alam dengan manusia, telaah kritis terhadap ilmu pengetahuan moden dan signifikasi ilmu pengetahuan dalam Islam yang merupakan hal yang integral dalam tradisi intelktual Islam. Kemudian agenda yang lainnya adalah untuk memperluas kesadaran akan ajaran syariah mengenai perlakuan etis terhadap alam dan memperluas bidang aplikasinya sesuai dengan prinsip syariah itu sendiri. Ia pun berkesimpulan bahwa problem dan krisis peradaban manusia modern tersebut dan berakar pada polusi jiwa manusia yang muncul ketika manusia barat mengambil alih peran ketuhanan di alam dengan menyingkirkan dimensi ilahi dari kehidupan. Oleh karen itu ia menekankan signifikasi religiusitas dalam upaya membangun ilmu pengetahuan.
