Abstract

Human Intelligent is note only verbal, but it has variety of brand. At least, there are five kinds of intelligences of human being: spiritual, emotional, rational, social and physical. The fifty kinds of intelligences have to get the same opportunity to expand, especially emotional and spiritual intelligence, because those two potencies of intelligences are often disregarded.To develop all potencies of intelligence above requires five-education phase: (a) the recognition, (b) the experience, (c) the innovation, (d) the comprehension, and (e) the practice. In addition, it needs good cooperation between teacher and parent. Each has to give guidance, which has orientation, democratic and full of affection.Keyword: potencies of intelligence and intelligent education.

Abstract

Harmful algal blooms (HABs) cause various problems, such as water quality degradation, fauna mass mortality and impairment of human health. Water quality monitoring in Lampung Bay has been conducted by Lampung Marine Aquaculture Office (BBL) of the Ministry of Marine Affairs and Fisheries since 1994. Occurrence of Pyrodinium bahamense var. compressum (Pbc), a causative organism of paralytic shellfish poisoning (PSP), has been recorded but threats caused by HABs have never been reported. A study aimed to know the level of public knowledge and awareness about HABs in Lampung Bay has been conducted. The components of group respondents consisted oflocal governments, academics and coastal communities. Awareness from each component was examined includinggeneral HAB knowledge, HAB impact to the community, HAB occurence and local knowledge of HAB. Data of HAB knowledge were collected through questionnaire and focus group  discussion. The result showed that 40.5% of respondents had knowledge of HABs phenomena and 51.3% respondents only know signs or indicators of HAB occurrence, while only 1.4% respondents had knowledge of local HAB occurences. The direct impact of HABs to the community was not commonly known by the respondents. Only a few cases of poisoning after eating seafood were reported. It can be concluded that there was lack of public knowledge and awareness on HABs in LampungBay. Intensive public awareness programs about HABs should be conducted in order to reduce risk towards HABs in Lampung Bay.

Abstract

Seasonal changes of Pseudo-nitzschia diel dynamics in an estuarine ecosystem have been known to be regulated by salinity, water temperature and nutrient dynamics. In this study, we aimed to investigate the effect of these physical-chemical factors on the diel pattern of the Pseudo-nitzschia population in the Cisadane River estuary.Plankton samples were collected from a diel station at two different periods, in the dry season (May-June) and thewet season (September). Plankton samplings were done in a 24 hour period with 3 hourly sampling intervals. The result showed a higher abundance of Pseudo-nitzschia in the dark-period during the dry season, while during the wet season the abundance was higher in the light-period. Nitrate and phosphate concentrations were suggested as important factors in facilitating Pseudo-nitzschia maxima. The low abundance of Pseudo-nitzschia in the estuarycould be due to the relatively low N:P ratio (<10). The results showed that the Cisadane River estuary was strongly influenced by seawater during the night and by freshwater during day. The GLM analysis suggested that there were changes in the species omposition of the Pseudo-nitzschia population in the ecosystem. The oligohaline species was found to be abundant in the dry season, the maxima occurred at night, which is probably related to a highermarine influence in the ecosystem. Conversely the polyhaline species was abundant in the wet season, with the maxima occurring during daylight, which might be related to a stronger freshwater influence in the ecosystem.

Abstract

ABSTRACTTin mining in the coastal waters of West Bangka Regency is known to affect water quality, which has an impact on the phytoplankton community structure. This research aims to study phytoplankton communities in mining tin areas and outside of mining areas (non-mining areas). Sampling was carried out in 22 sampling stations with 7 stations in the tin mining area. Phytoplankton samples were taken by the vertical haul method. Zooplankton sampling and measurement of water parameters in the form of temperature, pH, and salinity were also conducted to determine the relationship of these parameters with the phytoplankton community. Based on the density of phytoplankton in the water column, the coastal waters of West Bangka are generally in the category of oligotrophic with cell densities ranging from 3.6 × 105 - 1.6 × 107 cells.m-3. The results of the IS-ID analysis showed a difference of 56% in phytoplankton community structures in the mining and non-mining areas of West Bangka coastal. Although no differences were found in the number of phytoplankton genus present, phytoplankton cell density in the waters around the tin mining area was found to be lower compared to the waters in the non-mining area. Differences in community structure and phytoplankton cell density in mining and non-mining areas are thought to be related to mining activities in the coastal. However, further studies are needed to study the magnitude of the influence and exact cause of the emergence of differences in community structure and phytoplankton density.Keywords: Tin mining, spatial distribution, phytoplankton community, Bray-Curtis clustering ABSTRAKPenambangan timah di perairan pesisir Kabupaten Bangka Barat diketahui dapat mempengaruhi kualitas perairan sehingga berdampak pada struktur komunitas fitoplankton. Penelitian ini bertujuan untuk mempelajari komunitas fitoplankton di kawasan tambang timah pesisir (mining) dan di luar area tambang (non-mining) di pesisir Bangka Barat. Pengambilan sampel dilakukan pada bulan Oktober 2012 di 22 stasiun sampling, termasuk 7 stasiun sampling yang berada di area penambangan timah. Sampel fitoplankton diambil dengan metode vertical haul menggunakan jaring Kitahara (mata jaring 80 µm). Pengambilan sampel zooplankton dan pengukuran parameter air berupa suhu, pH, dan salinitas juga dilakukan untuk mengetahui hubungan parameter tersebut dengan komunitas fitoplankton di area kajian. Berdasarkan densitas fitoplankton di kolom air, perairan pesisir Bangka Barat secara umum berada dalam kategori oligotrofik dengan densitas sel berkisar antara 3,6×105 – 1,6×107 sel.m-3. Komunitas fitoplankton di Bangka Barat terdiri atas 28 genus, mencakup 23 genus Diatomae dan 5 genus Dinoflagellata, dengan Bacteriastrum, Chaetoceros, Thalassiothrix, Rhizosolenia, dan Pseudo-nitzschia sebagai genera paling dominan di perairan. Hasil analisis IS-ID menunjukkan perbedaan sebesar 56% pada struktur komunitas fitoplankton di area mining dan non-mining perairan Bangka Barat. Meskipun tidak ditemukan perbedaan pada jumlah genus fitoplankton yang hadir, densitas sel fitoplankton di perairan sekitar kawasan mining timah ditemukan lebih rendah dibandingkan dengan perairan yang ada di kawasan non-mining Kabupaten Bangka Barat. Perbedaan struktur komunitas dan densitas sel fitoplankton di area mining dan non-mining diduga terkait dengan aktivitas penambangan di perairan pesisir Bangka Barat. Namun diperlukan kajian lebih lanjut untuk mempelajari besar pengaruh dan penyebab pasti munculnya perbedaan struktur komunitas dan densitas fitoplankton tersebut. Kata kunci: Tambang timah, distribusi spasial, komunitas fitoplankton, Bray-Curtis clustering

Abstract

Abstract: There is a new method of marketing for a company to compete in digital era which is gamification. Gamification means inserting a game experience in non-game context to create value for the customer. Gamification could create customer engagement and customer loyalty for business and to achieve the business’ goals. This study want to investigate the relation of gamification with customer engagement and customer loyalty on Gojek. This research is using online survey for gathering the data from 232 respondents in Bekasi and Jakarta and the data will be analyse using PLS- SEM. Based on the findings, gamification is having a correlation towards customer engagement and customer loyalty on Gojek. The relationship between gamification and customer engagement are strong means gamification is an effective strategy to increase customer engagement, meanwhile relationship of customer engagement and customer loyalty are weak, so as gamification and customer loyalty means gamification is not always an effective strategy to create customer loyalty. It also concluded that rewards, challenges and points are the important gamification elements. Moreover, it is advised for the company to improve gamification elements as it to retain the engagement and loyalty for the customer and to support the gamification program with other marketing strategy.Keywords: Gamification, Customer Engagement, Customer Loyalty, Gojek.

Abstract

Indonesia's soft power policy in foreign policy for peace in Afghanistan is because at this time there are several similarities in religion which are the most easily accepted things in both countries. The problem under study is how to determine several criteria for the factors that encourage Indonesia to help bring peace in Afghanistan. The research method used is a combination method, a combination of qualitative and quantitative, with the process of collecting data through interviews and questionnaires to six experts in soft power efforts for peace in Afghanistan. Meanwhile, data analysis used the Delphi and Borda technique. The results show that seven reasons drive the need for Indonesia to use soft power for peace in Afghanistan, namely Indonesia's aspirations in realizing world peace (27%), Building the image of Indonesia as a peace bridge country (21%), Encouragement from Community Organizations (18 %), Studying Islam as the religion of Rahmatan lil Allamin (12%), Indonesia's proximity to Afghanistan and equality of identity (9%), Learning to handle conflict (8%) and Learning the values of Pancasila (5%).
