PENANGANAN PRODUKSI BUAH PISANG PASCA PANEN MELALUI MODEL PENGENDALIAN GAS ETILEN
Bananas is a kind of fruit that has many benefits and economic value. However, because it is perishable, an unappropriate post-harvest handling will decreasing the economic value. Many factors affect the ripening of bananas, one of it is ethylene gas. The ethylene gas that contained in the banana flows from the higher concentration to the lower one. The flow should be controlled in order to make it decaying properly. Temperature is a parameter that affects the flow of ethylene. This research offers storage temperature regulation such that the life time of banana could be extended. A mathematical model that represents the ethylene flow among the subpopulations is discussed. The population are devided into sub-population of unripe bananas, normal ripe bananas, ripe bananas wounds, and rotten bananas. The Stability of the model is evaluated in the critical point by Jacobian matrix and the Routh Hurwitz Criteria. The control is design by minimizing the temperature parameters using the Pontryagin Minimum Principle. Simulation is ilustrated in four cases, the firts case is no bananas wound initially, second case is no bananas rot initially, third case is no ripened normal bananas initially, and the fourth case is the bananas ripe initially exiting. The simulations shows that before controling the temperature, in the amount of 120 bananas of firts case, the proces is condcuted in sixteen days, ten days for the second case, nine days for the third case, and eight days for the fourth case. After controling the temperature, for some amount of bananas of firts case, the proces is conduted in seventeen days, eleven days for the second case, ten days for the third case, and nine days for the fourth case

Forest fires impact a very serious problem because it could cause health problem, especially respiratory disease such as (ISPA), Asthma and Bronchitis. The study of the health disorders is conducted by consider mathematicaly the spread of disease due to forest fires smoke. The model is constructed by devide the human population into six subpopulations, that is vulnerable S(t), exposed E(t), Asthma infected A(t), Bronchitis infected B(t) and recovered R(t).The governed model is analyted at every critical points using Routh-Hurwitz method. The results gives two critical points that describe a free disease conditions ( ) and an endemic conditions ( ). A stabil ( ) is occured if and where the threshold point of the stability is expressed as and . Endemic conditions will be asymptotically stable when and with . The condition of free disease of forest fires is occured in a long time period, while the endemic conditions is occurred in a short time period. It could be interpreted that the disease spread due to the forest fires smoke is not easy to overcome

In conclusion, physical condition of house sanitation had six times risk of causing trend of pneumonia incidence among toddlers in Lambatee Village, Darul Kamal Subdistrict, Aceh Besar District
Sq Garden Street Child sebagai Upaya Penanaman Akhlakul Karimah pada Anak Jalanan di Kota Makassar
Ajaran islam bersumber dari Al-Qur\u27an dan As-Sunnah sehingga pemeluknya dapat mengetahui hal yang seharusnya dikerjakan, tetapi berdasarkan realita yang terjadi banyak penyimpangan yang dilakukan oleh pemeluknya seperti oleh anak jalanan. Anak jalanan merupakan salah satu permasalahan yang memerlukan perhatian yang sangat besar. Kurangnya pemberdayaan anak jalanan tersebut membuat anak jalanan di kota Makassar semakin bertambah begitupun dengan angka kriminalitas yang terjadi, hal ini di karenakan pergaulan yang tidak sehat pada lingkungan anak. SQ Garden street Child adalah taman kecerdasan spiritual anak jalanan yang didalamnya anak jalanan akan diajarkan tentang ilmu keagamaan dengan menggunakan pendekatan emosional, sehingga adanya SQ Garden street Child akan mempengaruhi perkembangan karakter anak jalanan khususnya di kota Makassar dan diharapkan anak jalanan sebagai generasi muda islam kebanggaan bangsa dalam kehidupannya selalu dilandasi dengan karakter akhlakul karimah

The good, the bad and the hijab: A study of implicit associations made by practicing Muslims in their native Muslim country
Recent research indicates that wearing the hijab reduces the attractiveness of female faces perceived by practicing Muslim men and women in their native Muslim country (the United Arab Emirates). The purpose of the current research was to develop this finding to investigate whether other aspects of person perception are also affected when women wear the hijab in this Muslim country. Of particular relevance is that changes in physical attractiveness often affect the personal qualities assigned to individuals. Accordingly, we sought to determine whether such effects occur when the physical attractiveness of women is altered by wearing the hijab. To do this, we used an Implicit Association Test (IAT) to investigate how native Muslim participants in the UAE associated pleasant and unpleasant connotations with images of women either wearing the hijab or with their heads uncovered. As in previous research with native Muslim participants, female faces were again perceived as significantly less attractive when the hijab was worn. However, the accompanying IAT findings showed that these less attractive hijab-wearing images were associated more with pleasant connotations than were the matched uncovered images. These findings provide fresh insight into the effects of the hijab on perceptions of Muslim women in a Muslim country and provide support for the view that cultural clothing can influence person perception beyond physical attractiveness alone.WOS:00079989440000
PrekotAC as a new filter aids material for fabric filter in air filtration system
Fabric filter has a short life span due to wear and tear influenced by the operating conditions of the system. Treatment of fabric filter using pre-coating material is one of the simplest technique to overcome this problem where it works as a filtration aids that will coat a layer of inert material onto the surface of the fabric. Pre-coating acts as a barrier to block and remove undesired particles from gas stream but allowing a uniform air flow passing through the filter media. The morphology of dust cake that accumulated on the surface of the filter media depends on several properties of the particles such as shape and size. Hence, study presents the characterization of a newly formulated filtration aids known as PrekotAC consisting of a different combination of pre-coating material PreKot™ and activated carbon. The aim is to determine the best combination of PrekotAC admixtures as a filtration aids suitable for a fabric filtration system. Various characteristics of the formulated admixtures such as its particle size distribution, bulk density, moisture content as well as its morphology were investigated and presented in this paper
