The most important devices for digital campus development are computer network, Internet, and content. Computer network and Internet depend on the outside factors, i.e. vendors and technology suppliers. The last devices depend on the internal factor but it must be suitable by the users. The users in digital campus include all of the students, lectures, and the non-academic staff. This paper is not only to propose how to manage the content of digital learning but also to propose the digital learning model and the development of cyber campus in State College of Islamic Studies of Purwokerto, Central Java.

: Education deals with enlightening people and developing human resources. The reasecher concluded that cultural background of students influences their learning attitude in the school. Therefore, the developing learning process of Natural Sciences insist student to elaborate principles of Natural Sciences without ignoring cultural valuesof local community. The policy of decentralization of Indonesian Government had authorized and legitimated local authorities to develop curriculum based on the local cultures. To do so, each local government through the officers of Education has to create a curiculum by involving some curriculum experts, instructures, natural sciences theachers, and the lectures of universities who adequately understand learning model of Natural Sciences.

Perfume is a cosmetic product that widely used by people to improve their appearance in social interactions. Perfume released specific fragrance from the essential oil. Manufacturers often mix the pure essential oils with hexylene glycol to reduce prices. Utilization of hexylene glycol as the solvent and diluent often reduce the odour profile of the perfumes. This paper investigated the development of an electronic nose (e-nose) based on a metal oxide semiconductor (MOS) gas sensor to detect hexylene glycol in perfumes. E-nose in this study was developed using MOS gas sensors from Figaro and Raspberry series, including TGS 822, TGS 826, TGS 2600, TGS 2620, MQ2, MQ3, MQ8, and MQ135. For the experiment, we collected 10 brands of commercial perfumes from the supermarket around Purwokerto, Central Java. All samples of perfumes were analysed using gas chromatography-mass spectroscopy (GC-MS) to detect the concentration of hexylene glycol in the samples. The concentration of hexylene glycol in the samples identified none (0%), low (1-20%), moderate (21%-50%) and high (more than 50%). Afterward, 10 brands of perfumes were separated into 15 samples, totally created 150 samples. All perfume samples were measured using an e-nose to obtain the responses. Analysis of sensor responses using principal component analysis (PCA) showed that e-nose was highly performed to discriminate the samples based on hexylene glycol concentration. Classification of 150 perfume samples using backpropagation neural networks (BPNN) grouped 150 perfumes in four different classes in which the accuracy of classification reached 96.36% for the training dataset and 92.50% for the testing dataset, respectively.

Endogenous growth theory assumes that human capital is a prominent factor in regional economic growth. However, the imbalance of human capital between regions is still a major problem in economic growth in Indonesia. Previous studies on regional economic growth have recognized the importance of considering spatial aspects as a determinant of regional economic growth. The geographical area in the form of an archipelago with a large number of administrative districts and cities produces pros and cons regarding the influence of spatial aspects on the regional growth of urban districts. This study aims to analyze the distribution of human capital using the Alternative Human Development Index (AHDI) approach and the effect of human capital and spatial aspects on the regional economic growth of urban districts in Indonesia within the framework of endogenous growth theory. The research method uses geometric mean to measure the Alternative Human Development Index, Geographic Information System (GIS) to see the distribution of human capital and regional economic growth in Indonesia, and the spatial regression Spatial Autoregressive Moving Average (SARMA) used to analyze the spatial aspects of human capital and regional economic growth in Indonesia. The results show that human capital in Indonesia is still unequal between the western and eastern parts of Indonesia. Human capital and spatial factors have positive effects and are the most influential determinants of Indonesia's regional economic growth, as indicated by the value of the spatial lag weight matrix of the dependent variable (ρ) and the spatial error term (λ) that is positive.

Since 1968, socio-economic and infrastructure development focused on the accessible region such as urban and sub-urban area. Rural, rim-land, coastal area, highland, and isolated area were still ignored in national development priorities by the central and local government. This paper discusses the spatial analysis of disparities in Banyumas Regency, Central Java, based on indicators of socio-economic and infrastructure. We had collected data by doing a survey in 27 sub-districts in Banyumas Regency. Disparities in socio-economic development and infrastructure were measured using 14 variables, i.e. unemployment rate, consumer price index, wage index, poverty index, quality of life, quality of health, quality of education, criminal rate, quality of roadway, public transportation accessibility, quantity of traditional market, quantity of bridge, and the quantity of public school building. Multivariate statistical analyses based on the principal component analysis (PCA) and hierarchical cluster analyses (HCA) were used to analyze the disparities. The analysis on 14 socio-economic parameter displays that unemployment rate, poverty index, quality of health, and quality of education are the main contributor for socio-economic and infrastructure disparity. Ajibarang, Gumelar, Cilongok, and Rawalo had still a classic problem in economic development due to being the pockets of unemployment and poverty in Banyumas Regency. Based on social indicators, 6 sub-districts including Gumelar, Karanglewas, Lumbir, Pekuncen, Somagede, and Tambak should receive more attention by local government due to a high percentage of poor people to access medical and health facilities. In addition, the ratio of people who are able to access higher education in Jatilawang, Purwojati and Wangon was still less than 10%. There were no significance disparities in infrastructure indicator because the infrastructure had been developed equally in all sub-districts in Banyumas Regency. Keywords : patial disparities, socio-economic development, infrastructure, multivariate analyses

Turmeric contains bioactive compounds that are efficacious for human health. A breakthrough of simpler and lower-cost identification techniques is needed to utilize it. This paper aims to investigate the development of chemo-selective gas sensors for identifying α-curcumene, ar-turmerone, curlone, and β-sesquiphellandrene. Four chemo-selective sensors were created using quartz crystal microbalance (QCM) sensors coated with molecularly imprinted polymers to identify each of those compounds. The polymers were prepared using polyacrylic acid, hydrochloric acid, and pure target compounds (α-curcumene, ar-turmerone, curlone, and β-sesquiphellandrene). The turmeric odor from 10 different samples was exposed to QCM sensors. The changing frequency of QCM sensors due to the mass loading of target compounds on the surface of QCM sensors was recorded to analyze the performance of QCM sensors. The result of the principal component analysis showed that the QCM sensors performed well and could distinguish the turmeric samples at five combinations of the compounds. The turmeric sample classification using backpropagation neural networks reached high accuracies, with 97.04% in training and 98.73% in testing datasets. These findings indicate that the employment of sensory analysis using QCM sensors has the prospect of being a complementary technique for identifying bioactive compounds.
