This study aims to investigate the dynamics of the effects of world crude oil prices and world rice prices on Indonesia's inflation rate in the period between January 2004 and September 2015. Monthly time series data spanning from January 2004 to September 2015 are analyzed using difference equation model as the econometric tool. Test result shows that there existed a dynamic effect of world oil crude prices and world rice prices on inflation rate in Indonesia. The World crude oil prices positively affected the inflation rate in that each 1% increase (decrease) in the world crude oil prices caused the inflation rate to go up (drop) by 0.33%. The world rice prices also positively affected the inflation rate, where each 1% increase (decrease) in world rice prices was followed by a 0.52% rise (fall) of the inflation rate.

This research has a goal for analyzing determinant demand of telecommunication services either mobile phone or internet in Indonesia. This research uses secondary data of publication result from the Indonesian Central Bureau of Statistics in 2012-2013 period for 34 provinces in Indonesia. The demand for mobile phone is considered as the function of Gross Domestic Product (GDP) per capita and the region for dummy while the demand of internet service is the function of mobile phone service request, GDP per capita, proportion of educated society, proportion of the employment, and the region as a dummy. This research also modifies the model by placing the region as a moderating variable on GDP per capita. Furthermore, it is also done by using reduced form (mediation) to estimate the indirect effect on mobile phone ownership towards internet service request. The result of research showed that the demand for mobile phone and internet in Indonesia was influenced by income factor (GDP per capita). Yet In Indonesia, there are still imbalances in adapting the information technology (internet) between the area of Java-Bali and the outside of those areas. The result of research also showed that the demand for the telephone was able to be mediation of internet use. However, some regions (Maluku and Papua) have not optimally exploited mobile phone to access the internet compared to other regions.

Penelitian ini bertujuan untuk mengkaji ketersediaan bahan baku dan skala pemasaran industri pengolahan hasil perikanan di Kabupaten Konawe Selatan. Penelitian dilaksanakan pada tahun 2017 dan 2018 dengan menggunakan data primer dan sekunder. Data primer diperoleh melalui kuesioner yang didistribusikan kepada 21 responden pelaku usaha. Data sekunder diperoleh melalui publikasi Badan Pusat Statistik (BPS), Dinas Kelautan dan Perikanan, serta Dinas Perindustrian dan Perdagangan Kabupaten Konawe Selatan. Data diolah melalui analisis deskriptif dan SWOT. Hasil penelitian menunjukkan bahwa kekuatan industri pengolahan hasil perikanan di Kabupaten Konawe Selatan karena bahan baku bersumber dari potensi lokal, namun kelemahannya adalah bahan baku tersebut masih fluktuatif. Kendala bahan baku dialami khususnya oleh industri fermentasi, pengasapan, dan pengeringan ikan. Selain faktor musiman, ketersediaan bahan baku juga terkendala karena bahan baku sebagian besar berasal dari nelayan tradisional dengan struktur armada perikanan yang didominasi oleh nelayan skala kecil. Dengan demikian, pengembangan industri hasil perikanan mensyaratkan perbaikan di sektor hulu melalui sinergitas kebijakan penanganan keterbatasan bahan baku dari berbagai lembaga terkait. Sementara itu, temuan penelitian menunjukkan bahwa 24% unit usaha telah menembus pasar nasional. Ketersediaan bahan baku juga terkendala karena 28% telah menembus pasar regional, sisanya 48% hanya mampu memasarkan produknya di wilayah lokal. Kelompok industri yang hanya menjangkau skala lokal, yaitu industri pelumatan, pengasapan, dan pemindangan, serta beberapa usaha makanan olahan hasil perikanan. Bagi industri yang mengalami jangkauan pasar yang rendah akibat minimnya ketersediaan bahan baku, maka dapat menggunakan bahan baku pengganti namun tetap mempertahankan kualitas produk sesuai dengan selera pasar.Title: Fish Processing Industry in South Konawe Regency,  South East SulawesiThis study aimed to examine the availability of raw materials and the marketing scale of fish processing industry in South Konawe Regency. This research was conducted in 2017 and 2018 using primary and secondary data. Primary data were collected through questionnaires from 21 respondents. Secondary data were collected from Statistics Indonesia, Fisheries and Marine Affairs Office, and Industry and Trade Affairs of South Konawe Regency. Data were analyzed with descriptive analysis and SWOT analysis. The results found that raw material from local sources is the major force of fish processing industry. However, the fluctuating condition of its availability becomes the weakness. Fermentation, smoked fish, and dried fish processing industries suffer from this raw material problems. In addition, the availability of raw materials also largely depends on fishing results from small-scale traditional fishers. Therefore, the development of the fish industries need some specific improvement in the upstream section through the synergy on policies regarding raw material management from related institutions. Meanwhile, the research finding showed that 24% of business units have penetrated national market 28% have penetrated regional market, while the remaining 48% have only penetrated local market. The local industries were pulverized, smoked fish, fish brine, and some other fish processing industries. Those who could only reach small market area due to limited availability of raw materials are able to use substitute materials in a similar quality of market preferences.
