Abstract

Ozone Permukaan (O3) terbentuk karena adanya proses fotokimia oleh perkusor pembentuknya salah satunya yaitu gas karbonmonoksida (CO). Dengan menggunakan data parameter gas CO dan O3diurnal hasil pengukuran di Stasiun GAW Bukit Kototabang dan Lapan Bandung,dianalisis untuk mengetahui profil diurnal gas CO dan O3 pada tipe wilayah Urban (Bandung) dan Non Urban (stasiun GAW Bukit Kototabang). Konsentrasi dan profil gas CO secara diurnal untuk wilayah tipe Urban dan Non Urban ditentukan oleh sumber serta waktu emisi dari CO. Untuk wilayah type Urban, grafik diurnal konsentrasi gas CO terjadi puncak dan lembah. Puncak konsentarsi CO terjadi saat warga kota beraktifitas dengan berefek pada emisi gas CO, sedangakan lembah konsentrasi gas CO adalah periode pembentukan O3 melalui proses fotokimia. Untuk wilayah Non Urban (Stasiun GAW Bukit Kototabang) tidak terjadi perbedaan nilai konsentasi yang besar untuk periode tertentu mengingat kedudukan stasiun GAW Bukit Kototabang jauh dari sumber emisi gas. Status kualitas udara tahun 2008 untuk wilayah kota bandung dan Stasiun GAW Bukit Kototabang masih pada kriteria sehat karena nilai dari CO dan O3 masih berada jauh pada dari nilai ambang batasnya.

Abstract

The purpose of this research was to evaluate know the position of the best banana chips products and attributes of various kinds of banana chips. This objective of this study was  to determine the level of consumer preference to a product that was banana chips. At this time which was still the lack of efforts of producers in developing their products.  This research were carried out experiments using seven producs (brand of banana chip), which consists of KP1: Wahana, KP2: Alfamart, KP3: Mekar Jaya, KP4: Sumber Hidup,  KP5: Winda, KP6: Elsa Snack, and KP7: Yadi Bersaudara.  Data were analyzed statistically by using a Preference Test Mapping with assistance XL STAT software version 2014. Test hedonic and descriptive test analyzed were using Principal Component Analysis(PCA). Agglomerative hierarchical clustering (AHC) was used to see all grades of banana chips. Based on the descriptive analysis using PCA and hedonic analysis using the AHC showed that banana chips KP7 and analysis of the main components of the descriptive (PCA) test were then analyzed by using the preference mapping technique, with the sensory attributes used in banana chips products are banana flavor, saltiness, sweet taste, burnt, savory, crunchy, yellow, brownish yellow, banana scent, vacancy rate, texture crispness. The most preferred product in the study were Winda banana chips, Elsa Snack, and Yadi Bersaudara most favored by panelists. Keywords:Banana chips, consumer preferences, PCA, AHC.

Abstract

Pengamatan Aerosol merupakan salah satu program pengukuran yang dilakukan di Stasiun Pemantau Atmosfer Global Bukit Kototabang. Penelitian ini bertujuan untuk mengetahui tren konsentrasi Aerosol (Black Carbon, Particulate Matter (PM10) dan Scattering Coefficient) di Stasiun Pemantau Atmosfer Global Bukit Kototabang dan untuk melakukan penelitian terhadap dampak kemunculan titik panas di Sumatera dengan pemantauan Aerosol. Penelitian ini dilakukan menggunakan data pengamatan pada bulan Februari 2016-2019. Metode yang digunakan yaitu dengan pengamatan yang dilakukan selama 24 jam melalui instrumen Catcos Magee Scientific Aethalometer untuk pengamatan Black Carbon, BAM 1020 untuk pengamatan PM10, Ecotech M9003 Integrating Nephelometer untuk pengamatan Scattering Coefficient dan pantauan titik panas (hotspot) di pulau Sumatera diambil dari data harian titik panas dari Satelit MODIS (Terra, Aqua, dan SNPP) dengan tingkat kepercayaan diatas 70%. Hasil penelitian ini menunjukan konsentrasi PM 10 dan Aerosol Scattering Coeficient meningkat pada Februari 2019 dengan bertambahnya jumlah titik panas yaitu 367 titik dan arah pergerakan angin dominan dari timur dan timur laut. Sedangkan peningkatan titik panas pada tahun 2018 meningkatkan konsentrasi Black Carbon dan PM10

Abstract

Being a leader is an easy thing, but being a good leader and being able to carry out the mandate or responsibility is not an easy matter. In Islam itself being a leader or caliph is one of the tasks and goals of humans so that Islam is so careful about matters of leadership. In various verses it is explained related to the concept of leadership, the characteristics of an ideal leader to how to choose a leader in Islam. by using the comparative method, this journal will examine the characteristics of a leader contained in several interpretations interpreted by interpreters. Many in the Qur'an mention the theme of leadership by using various kinds of vocabulary, each word of course has a different meaning and interpretation. Among other things, Hamka's interpretation in Surat al-Maidah verse 57 states that the Koran instructs Muslims not to elect leaders from non-Muslims. Buya Hamka in his commentary on al-Azhar further mentions that there are eight qualifications for leaders, namely: being Muslim, male, intellectual prowess, physical strength, trustworthiness, fairness, honesty and wisdom. As for Tafsir Tanwir from Muhammadiyah which makes Rasulullah and Prophet Ibrahim as examples of ideal leaders who need to be emulated and whose characteristics leaders need to have. According to Ibn Kathir's Interpretation, his interpretation does not merely forbid Muslims from choosing non-Muslims to be leaders, but also forbids even being made close friends, friends and also being appointed as administrators who take care of Muslim matters. According to Jawad Mughniyah in Al-Kasyif's interpretation, for the husband's leadership in the household, to lead his wife, not to become a ruler or dictator.
