"Wearable sensor technology is evolving in parallel with the demand for human activity monitoring applications. According to World Health Organization (WHO), the percentage of health problems occurring in the world population, such as diabetes, heart problem, and high blood pressure rapidly increases from year-to-year. Hence, regular exercise, at least twice a week, is encouraged for everyone, especially for adults and the elderly. An accelerometer sensor is preferable, due to privacy concerns and the low cost of installation. It is embedded within smartphones to monitor the amount of physical activity performed. One of the limitations of the various classifications is to deal with the large dimension of the feature space. Practically speaking, a large amount of memory space is demanded along with high processor performance to process a large number of features. Hence, the dimension of the features is required to be minimized by selecting the most relevant feature before it is classified. In order to tackle this issue, the hybrid feature selection using Relief-f and differential evolution is proposed. The public domain activity dataset from Physical Activity for Ageing People (PAMAP2) is used in the experimentation to identify the quality of the proposed method. Our experimental results show outstanding performance to recognize different types of physical activities with a minimum number of features. Subsequently, our findings indicate that the wrist is the best sensor placement to recognize the different types of human activity. The performance of our work also been compared with several state-of-the-art of features for selection algorithms."

"Environmental crisis is in principal brought about by human activities. Therefore, it is required to exercise new approach towards the environment, that is ethical approach by which principles and moral guidance for human behaviors are put forward. This article is to describe Yusuf al-Qaraḍāwy’s thought of Islamic-ethical concept on environment, and its relevance with the handling of environmental-global crisis. His thought is based on Islamic jurisprudential and ethical values. Values of the former are the followings: planting barren land, keeping cleanliness, cultivation, and forestation, meanwhile those of the latter are the application of al-ihsān concept, being friendly with environment, destructive prohibition, justice, gratitude, and simplicity. Al-Qaraḍāwy’s concept is absolutely appropriate for the prevailing environmental-global crisis. It is hoped that Indonesian Muslims, as majority group, would like to comprehend the concept and to build consciousness of religious way of thinking towards the environment. Hopefully, this concept is workable for coping with the environmental crisis, as well."

"Dalam ranah ilmu geologi, kandungan polen dalam sedimen dapat digunakan untuk mengetahui pengaruh aktivitas manusia terhadap lingkungan. Hal ini dilakukan dengan merekonstruksi ulang perubahan bentang vegetasi berdasarkan kandungan polen dan spora yang ada di dalam sedimen. Kehadiran charcoal dalam sedimen khususnya yang diambil dari wilayah tropis juga dapat mengindikasikan budaya masyarakat yang berkaitan dengan pembukaan lahan. Umumnya pembukaan lahan di Indonesia dilakukan dengan cara membakar hutan. Penelitian ini bertujuan untuk merekonstruksi perubahan bentang vegetasi dan sejarah api yang terjadi pada Kala Antroposen di Teluk Balikpapan, Kalimantan Timur. Pendekatan yang dilakukan dalam penelitian ini yaitu dengan melakukan analisis terhadap data palinologi, charcoal, dan umur absolut berdasarkan metode ²¹⁰Pb. Terdapat dua belas perconto dengan panjang 110 cm dan interval 10 cm. Berdasarkan analisis yang telah dilakukan, sedimen yang diambil dari Teluk Balikpapan diendapkan pada lingkungan hutan bakau yang ditunjukkan oleh kelimpahan Rhizophoraceae dengan frekuensi yang sangat tinggi. Perubahan bentang vegetasi yang terjadi pada tiap zonasi polen berkaitan dengan aktivitas manusia seperti pembangunan kilang minyak, pertambangan batu bara, pembangunan kota, dan eksploitasi hutan. Sementara sejarah api menunjukkan bahwa penggunaan api di sekitar Teluk Balikpapan sudah cukup intensif sekitar 100 tahun yang lalu yang dipengaruhi oleh kondisi cuaca yang berkaitan dengan peristiwa ENSO (El Niño-Southern Oscillation), IOD (Indian Ocean Dipole), dan Proyek Sawah Sejuta Hektar. Intensitas api yang tinggi berkaitan dengan periode ENSO kuat. Berdasarkan data palinologi dan data charcoal, dapat disimpulkan bahwa perubahan bentang vegetasi dan sejarah api tidak memiliki kaitan.

In the realm of geology, the pollen content in sediments can be used to determine the effect of human activities on the environment. This is done by reconstructing changes in the vegetation landscape based on the pollen and spore content in the sediment. The presence of charcoal in sediments, especially those extracted from tropical areas, can also indicate community culture related to land clearing. Generally, land clearing in Indonesia is carried out by burning forests. This study aims to reconstruct changes in vegetation landscape and fire history that occurred during the Anthropocene in Balikpapan Bay, East Kalimantan. The approach taken in this study is to analyze data on palynology, charcoal, and absolute age based on the ²¹⁰Pb method. There were twelve samples with a length of 110 cm and 10 cm intervals. Based on the analysis that has been done, sediments taken from Balikpapan Bay were deposited in the mangrove forest environment shown by the extremely high abundance of Rhizophoraceae. Changes in the vegetation landscape that occur in each pollen zone are related to human activities such as the oil refinery construction, coal mining, urban development, and forest exploitation. Meanwhile, the history of fire shows that the use of fire around Balikpapan Bay was quite intensive about 100 years ago which was influenced by weather conditions related to the events of ENSO (El Niño-Southern Oscillation), IOD (Indian Ocean Dipole), and the Million Hectare Rice Project. High fire intensity is associated with periods of strong ENSO. Based on palynological and charcoal data, it can be inferred that there is no connection between changes in vegetation landscape and fire history."

"ABSTRAKKemunculan system kereta api Commuter Line mendorong masyarakat untuk mengakses stasiun dan naik kereta, alih-alih menggunakan kendaraan pribadi. Ini membuat stasiun menjadi titik di mana orang-orang dating dan pergi dan mendorong berkembangnya elemen-element perkotaan di kawasan sekitar stasiun seperti bangunan, halte bus, flyover, pagar stasiun, dan bahkan tiang listrik sebagai respon terhadap kehadiran stasiun. Orang-orang mulai membangun berbagai macam fasilitas yang mendukung para pengguna kereta, seperti toko, restoran, area parkir, titik transportasi lain, dan kawasan perumahan.

ABSTRAKThe presence of the Commuter Line train system encourages people to access the station and catch the train, instead of drive their private vehicles. This makes the train stations become the nodes for people to come in and encourages a development of the urban elements around the station such as buildings, bus shelter, flyover, station rsquo s fence and even electrical poles as the response of the station. People start to build facilities which can support the users of the Commuter Line, such as shops, restaurants, parking area, another transportation nodes, and residential area. When the commuters occupy the station rsquo s surrounding area, they begin to look and utilize the spots that formed from the urban elements to support their activities. Thus, this undergraduate thesis is based on the phenomena of the place development around the station that already become a new nodes within the city. Then, based on the phenomena, an observation of the Commuter Line surrounding area is conducted to understand how people utilize the urban elements in the mentioned area. "
