Isolate fungi selulolitik yang dikonsorsiumkan merupakan hasil isolasi dari limbah tanaman jagung yaitu isolate JB (Aspergillus sp.), JC (Fusarium sp.), JD (Aspergillus sp), JE (Rizoctonia sp.). Parameter yang diamati adalah sinergisme fungi selulolitik yang dikonsorsiumkan pada medium padat, pola interaksi antara fungi yang dikonsorsiumkan pada medium padat dan sinergisme fungi selulolitik yang dikonsorsiumkan pada medium cair (cocktail inokulum). Hasil penelitian menunjukkan bahwa dari konsorsium isolate fungi selulolitik diperoleh 5 pasangan isolat fungi selulolitik yang dapat bersinergi dan 1 pasangan tidak dapat bersinergi. Pola pertumbuhan yang terbentuk bersifat Mutual Intermingling (pasangan isolate JB vs JC dan JB vs JD), Partial Intermingling (pasangan isolate JB vs JE; JC vs JD; dan JD vs JE); dan Inhibition at touching point (pasangan isolate JC vs JE). Sinergisme fungi selulolitik yang dikonsorsiumkan pada medium cair (cocktail inokulum) menunjukkan tingkat pertumbuhan yang berfluktuatif seiring bertambahnya waktu fermentasi. Kesimpulan: dari 5 pasangan isolat fungi selulolitik yang dikonsorsiumkan diperoleh 1 pasang isolate yang tidak dapat bersinergis, dan sinegisme antara fungi membentuk pola interaksi yang bervariatif. Pertumbuhan fungi selulolitik pada medium cair berfluktuatif dan menunjukkan tingkat pertumbuhan optimum pada hari ke-3. Kata Kunci: fungi selulolitik, limbah jagung, sinergisme Abstract: The purpose of this study was to test the synergistic ability of cellulolytic fungi originating from corn waste to be sponsored as fibrous feed bioactivators. The cellulolytic fungi isolated were the result of isolation from corn waste, namely JB (Aspergillus sp.), JC (Fusarium sp.), JD (Aspergillus sp), JE (Rhizoctonia sp.) Isolates. The parameters observed were the synergism of the cellulolytic fungi that were sponsored on solid medium, the interaction pattern between the fungi that were consorted on solid medium and the synergism of the cellulolytic fungi which were consorted in the cocktail inoculum. The results showed that from a consortium of cellulolytic fungi isolates 5 pairs of cellulolytic fungi isolates that could synergize and 1 pair could not work together. The growth patterns formed are Mutual Intermingling (pairs of JB vs JC and JB vs JD isolates), Partial Intermingling (pairs of JB vs JE isolates; JC vs JD; and JD vs. JE); and Inhibition on touching points (pairs isolates JC vs JE). The synergism of the cellulolytic fungus, which was contorted in the cocktail inoculum, showed fluctuating growth rates with increasing fermentation time. Conclusion: from 5 pairs of consolatory cellulolytic fungi isolates obtained 1 pair of isolates who could not synergize, and synergy between fungi formed a pattern of varied interactions. The growth of cellulolytic fungi on liquid medium fluctuated and showed the optimum growth rate on day 3.: synergism, cellulolytic fungi, waste corn. Keywords: cellulolytic fungi, corn waste, synergism. 1.

    JURUSAN AKUNTANSI FAKULTAS EKONOMI UNIVERSITAS ANDALAS SKRIPSI IMPLEMENTASI PENERAPAN PSAK 109 TENTANG AKUNTANSI ZAKAT DAN SEDEKAH/INFAK (STUDI KASUS PADA BADAN AMIL ZAKAT NASIONAL (BAZNAS) DI KABUPATEN TANAH DATAR, KABUPATEN SIJUNJUNG, DAN KOTA SAWAHLUNTO) Oleh : RAHMAT LAILATUL QODRI 1610533011 Dosen Pembimbing : Vima Tista Putriana, SE., Ak., MSc., Ph.D., CA Diajukan untuk Memenuhi Salah Satu dari Sebagian Syarat- Syarat Guna Memperoleh Gelar Sarjana Ekonomi PADANG 2020 ABSTRACT The application of PSAK 109 concerning the accounting of zakat and alms / infaq in entities whose main operation is to collect and distribute zakat is very important. With the application of PSAK 109, it is hoped that the public's trust in the existing zakat management organization will increase, so that people prefer to distribute their zakat to zakat management organizations rather than issuing it personally directly to zakat recipients. The potential for zakat in Indonesia is very large, but it is not the same as the zakat collected by OPZ. This study aims to determine how the accounting treatment at BAZNAS Tanah Datar Regency, Sijunjung Regency, Sawahlunto City, and what the implications of the application of PSAK 109 on the performance of the collection and distribution of the three BAZNAS. This research belongs to the type of qualitative research, especially case studies. This research involved 3 cases, namely BAZNAS Tanah Datar, BAZNAS Sijunjung, and BAZNAS Sawahlunto. The results of this study show that the three BAZNAS still have not implemented PSAK 109 as a whole, and for BAZNAS Sijunjung, the application of PSAK 109 is still far from the accounting treatment according to PSAK 109.

  • January 14, 2016 Philips Signs Agreement with Indonesian
    January 14, 2016 Philips signs agreement with Indonesian Sijunjung Regency for full-scale implementation of new telehealth service in the region to help reduce maternal mortality Amsterdam, the Netherlands and Jakarta, Indonesia – Royal Philips (NYSE: PHG, AEX: PHIA) today announced an agreement with the Sijunjung Regency in West Sumatra, Indonesia, for the full-scale commercial implementation, Philips’ first globally, of its Mobile Obstetrics Monitoring (MOM) service in the region. This scalable smartphone-based digital health service is designed to identify mothers-to- be who are at high risk of pregnancy-related complications and help reduce maternal mortality rates. Expanding mobile monitoring coverage, it addresses both rural and urban needs. Philips works together with PT. TELKOM, the largest telecommunication provider in Indonesia with a nationwide connectivity infrastructure, to ensure a robust and effective digital solution. The MOM telehealth service is planned to be introduced in other regions in Indonesia, India and Africa later this year. The obstetrics monitoring solution enables midwives in remote locations to share vital measurements, observational data and mobile ultrasound images with obstetricians and gynecologists in the country’s larger hospitals and collaborate with them for improved decision making during pregnancy. The service features two mobile phone apps. The first allows midwives to collect vital measurement data - e.g. weight, blood pressure, temperature - and sync it to the MOM web portal. The second lets doctors track this data and review a woman’s progress. Specialists at regional primary care centers can also access the data via a MOM web portal to monitor women’s conditions and identify high-risk pregnancies via a dashboard interface.

  • Determinants of Inclusive Growth on the Inequality Abstract Introduction
    Advances in Economics, Business and Management Research, volume 97 Third International Conference On Economics Education, Economics, Business and Management, Accounting and Entrepreneurship (PICEEBA 2019) Determinants of Inclusive Growth on the Inequality Muhamad Kanzu Satrio1, Syamsul Amar2, Hasdi Aimon3 1 Universitas Negeri Padang, Padang, Indonesia, (e-mail) [email protected] 2 Universitas Negeri Padang, Padang, Indonesia, (e-mail) [email protected] 3 Universitas Negeri Padang, Padang, Indonesia, (e-mail) [email protected] Abstract This study presents an analysis of inclusive growth inequality during 2011-2016 and the influence of economic growth, health, education and government spending on infrastructure on inclusive growth inequality in West Sumatra province, Indonesia. To empirically analyze the phenomenon of economic growth inclusiveness, the Poverty-Equivalent Growth Rate (PEGR) method is used. With the PEGR method, an Inclusive Growth Index for inequality (IGin) was formed using the Gini index and 60 percent of the lowest population expenditure. The model used is the Random Effects Model panel data regression analysis. From the PEGR method, it was found that in the provincial aggregate, inclusive growth in inequality in West Sumatra still needed to be improved. Throughout the observation period the provincial aggregate only in 2014 experienced inclusive growth in inequality. Health has a positive and significant effect at the five percent significance level, while education has a positive and significant effect at the 10 percent significance level. Government expenditure on infrastructure has a negative and significant effect at the five percent significance level, while economic growth has no statistically significant effect for inclusive growth in inequality in West Sumatra in the 2011-2016 period.

This study aims to reveal the gold mines woman in Minangkabau.These women were seen as someone who works for establishment of food security in household economy at rural areas. Women gold miners have a big influence on food security in households economy at rural area, especially at Nagari IV Sawahlunto regenc.It has been known for ages that male became the dominant role,but in Minangkabau woman regarded as dominant role due its matrilineal system of social life. This research was qualitative research which is naturalistic or natural, it is also done on a particular natural background and case.The results of the study can be concluded that women gold miners occurred because of economic factors of the nuclear family and extended family. Besides that- social and cultural factors also became the reason for the alignment of Minangkabau tribes meaning who viewed that women have the same right to go into the public sector, especially to withstand the economic pressure. The involvement of women in the village market in terms of both economic and social culture has led to the transfer of knowledge and transfers of values not only in the nuclear family but also in the extended family.

There are four commodities that represent interregional trade of agricultural commodities in this study, namely: rice, chicken egg, broiler and fresh sea fish. This study uses cross section data of the 15 regencies/city in West Sumatera. The data is obtained from survey to wholesaler group of agricultural commodities in West Sumatera (primary data). The result of this study shows that factors affecting interregional trade in West Sumatera are: the difference in price (for commodities: rice, chicken egg and broiler), transportation costs (for commodities: broiler and fresh sea fish). Key Words: Interregional trade, Modified Gravity Model, Spatial Interaction. Paper Type: Research Paper Introduction During last two decades there has been a dramatic shift in stance development policy from "import substitution models" to "export-led growth model". This shift is driven by the economic recession that emerged in the 1970s. There are three factors that encourage the adoption of export-led growth model (Palley (2003: 1-29). First, at the time, many countries experienced slow economic growth and inflation which increases rapidly.

There has been a large increase in understanding the relationship between aboveground forest biomass and climate change in recent years. Aboveground Biomass (AGB) estimation is very important in understanding the contribution of forests to the regional carbon cycle. AGB in tropical forest areas is often carried out by utilizing the transformation of the vegetation index because the value obtained is a combination of several channels in the image to highlight the appearance of vegetation. Difficulties in field surveys due to tropical forest field conditions transform the vegetation index calculation is an effective alternative approach to estimate biomass. The purpose of this study is to estimate biomass by utilizing remote sensing data to estimate carbon stock. The study was conducted on tropical forests in Solok Regency, West Sumatra Province.
