Activation of Natural Zeolite as Water Adsorbent for Mixed-Adsorption Drying
Mixed-adsorption drying with material using zeolite is an option to improve product quality and energy efficiency of drying seeds. In this case, zeolite and seeds are mixed and fluidized by warm air as drying medium. The air will desorb water from seed, and at the same time, zeolite will adsorb vapor from air. Thus, the driving force of drying can be kept high. However, in Indonesia, the zeolite with high adsorption capacity is hardly found in market. This research studied the activation of natural zeolite using two different methods: by heating at 200-400oC, and adding NaOH 0.5-2.0 N. Results showed that the adsorbing capacity of zeolite activated by 1.0 N NaOH is 0.170 gr water/gr dry zeolite. While, by heating at 300oC for 3 hours, is 0.140 gr water loaded/gr dry zeolite. With the performance, zeolite can be used for drying application.

Musik Etnik dan Pengembangan Musik Gereja
Church, as a religious institution, and ethnic music, as a communality creation, are different thing. They have different philosophy, meaning, existence, entity, form, and also sosial and historical context. Sometimes even as, ideologically, they display even negation. However inspite of the contradiction, they have some interest and orientation i.e. come together on a place for expressing who people are. When they meet, there, they create something new. Based on Homi K. bhabha's theory, this something new is called "the third space". We will find ambivalence and mimicry in the new space. On the musical perspective, the hybrid of church and ethnic music call into being a new genre, namely "ethnical church music". The cutting-edge genre proved succeed for increasing worship atmosphere
Idiom Musik Klasik di Gereja Karismatik
Church music has long history and experiences in its periods. It began when they, the believers, mentioned themselves as the âChristianâ. From the time that phenomenon the christians commenced their act of devotion tradition included their musical tradition of worship. The existence of church music more developed till Middle Age or Dark Age Period. It was dominantly covering to others music genre. At the Renaisance Period, the church reformation movement occured and it was pioneered by Martin Luther. Western music changed at the time. Luther changed of scene; He changed the tradition of Catholic church that used Latin lirics to folk language; He changed the gregorian chant tradition with folksong. The phenomenon was the first time of event of inculturation in world history of music after it undergone stagnancy during the authorization of Roman empire, especially when Pope Gregory created the standarization to all christian music. At the present day we are familiar with charismatic music tradition which is developed from American music tradition. It has a characteristic which is used as the band instrument in praise and worship by christian believers. But sometimes, the believers also use arpeggio or broken-chord as the main charracter on Classical Period in part the way of Western music history. Pass through the reasearch, the reasearcher look into the idioms are used in praise and worship in charismatic church. The reasearcher found that the using of idiom in Classical Period has enriched the nuance of music aesthetic in praise and worship
DROUGHT EARLY WARNING SYSTEM AND PREPARATION OF PLANTING PATTERN OF GLOBAL CLIMATE CHANGES IN CONNECTION WITH MOBILE TECHNOLOGY-BASED
In developing countries, drought due to natural disasters such as flood result
in massive loss of farming practices. Warning communities of the incoming flood
provides an effective solution to this by giving people sufficient time to prepare and
protect their crop pattern and farm activities. However, the range of early warning
system solutions introduces a tangle of conflicting requirements including cost and
reliability, and creates several interesting problems from factors as diverse as
technological, social, and political. The complexity of these systems and need for
autonomy within the context of a developing country while remaining maintainable
and accessible by nontechnical personnel provides a challenge not often solved
within developed countries, much less the developing. After describing this problem,
the paper discusses a proposed solution for the problem, initial experiments in
implementing the solution, and lessons learned through that work.

Reduksi Volume Dan Pengarangan Kotoran Sapi Dengan Metode Pirolisis
The study was conducted to determine the change of mass, the shrinking volume and the heating value of char of cow dung induced by slow pyrolysis. The char produced by pyrolysis can be used as an alternative solid fuels. Besides, it can be a biochar as a mixture of biomaterial having a high-value materials. It due to the char has a high content of Carbon. In this experiment, the heating value of char was examined by using bomb calorimeter. The temperature pyrolysis was varied from 100°C to 500°C. Before the pyrolysis process, the feedstock was pulverized to a particle size of about 0.7 mm, and then it dried in the oven to have a moisture content up to 4%. The pyrolisis was conducted at varied temperatures and different heating rates from 0.13°C /sec to 0.29°C /sec.The results showed that the reduction of the cow dung volume performed significantly by the way of slow pyrolysis. The most reduced volume of cow dung occured very significant at the highest pyrolysis temperature, reaching 60% at 500°C. On the other hand, the heating rate variation did not influence in yield reduction, but it has an effect on the result of heating value of char. The results also indicated that the optimal of heating rate occured at 0.13°C/sec to 0.16°C/sec. In the visualization of the solid yield pyrolysis products, as higher pyrolysis temperature, as darker color of the char. It was shown the Carbon content in the char
SISTEM PENENTUAN KALORI HARIAN PENDERITA DIABETES MELITUS DENGAN MODEL LOGIKA FUZZY MAMDANI DAN METODE FUZZY C-MEANS CLUSTERING (FCM)
Saat ini penyakit diabetes sudah dikenal oleh masyarakat karena keganasannya jika sudah
menginfeksi manusia. Penyakit ini muncul ditandai dengan adanya gangguan sistem
metabolisme dalam tubuh yang disebabkan dari faktor keturunan atau konsumsi gula yang
berlebihan. Penderita Diabetes Melitus (DM) tingkat lanjut perlu untuk mengontrol
kesehatannya secara rutin, termasuk mengontrol konsumsi kalori harian. Ada 4 faktor atau
variabel yang mempengaruhi dalam penentuan kalori penderita DM yaitu usia, tinggi badan,
berat badan, dan aktivitas. Dalam menentukan nilai variabel biasanya tidak menggunakan nilai
absolute 0 atau 1, sehingga sering menimbulkan ketidakpastian dalam mengambil keputusan.
Logika fuzzy dapat digunakan untuk memecahkan ketidakpastian penyebab dari suatu masalah,
sehingga dapat diambil suatu kesimpulan yang pasti. Logika fuzzy banyak digunakan karena
diantaranya memiliki toleransi terhadap data-data yang tidak tepat/pasti. Permasalahan yang
terjadi jika hanya menggunakan model Mamdani, yaitu tidak ada pengelompokan data untuk
proses pembelajaran sistem yang menghasilkan knowledge base. Logika fuzzy juga mengenal
dengan istilah Clustering. Clustering merupakan proses pengelompokan data dalam kelaskelas
