Potensi produksi pertambangan emas di Indonesia termasuk dalam kategori cukup besar dengan produksi rata-rata 113.720,4423 kg/tahun. Penggunaan merkuri pada proses pengolahan emas berpotensi menyebabkan terjadinya masalah kesehatan seperti keracunan merkuri. Tujuan penelitian ini adalah menganalisis faktor risiko akumulasi merkuri pada rambut pekerja penambangan emas tanpa izin (PETI) di Desa Cisarua, Nanggung, Bogor tahun 2013. Penelitian ini adalah penelitian kuantitatif dengan pendekatan potong lintang. Populasi penelitian ini adalah seluruh pekerja PETI Desa Cisarua. Sampel diambil menggunakan teknik accidental sampling sebanyak 40 pekerja. Data dikumpulkan melalui wawancara dan pengamatan. Pengukuran konsentrasi merkuri dalam rambut pekerja menggunakan AAS FIMS dengan Reverence Recovery Material 100%. Variabel bebas pada penelitian ini adalah umur, masa kerja, jam kerja dan konsumsi ikan dengan variabel terikatnya adalah akumulasi logam merkuri pada rambut pekerja. Hasil penelitian menunjukkan bahwa rata-rata akumulasi logam merkuri dalam rambut pekerja antara 2,03 sampai 9,04 ppm atau terdapat 24 orang (60%) mengalami keracunan merkuri lebih dari 2 ppm. Faktor masa kerja (nilai p = 0,000) memiliki korelasi dengan akumulasi logam merkuri pada sampel rambut pekerja yang menunjukan korelasi positif dengan kekuatan sedang (r = 0,552). Hasil analisis multivariat dijelaskan dalam model (akumulasi logam merkuri = -0,315 + 0,896*masa kerja) dengan variabel Adjusted R Square masa kerja sebesar 52,6%.Indonesia has a quite large potential production of gold mining with average production 113.720,4423 kg/year. Gold mining production by mercury could cause health problems, such as mercury poisoning. The purpose of this study was to analyze the risk factor of mercury accumulation in hair samples from illegal gold mining (IGM) workers in Cisarua, Nanggung, Bogor in 2013. This research was a quantitative study by cross sectional approach. The population in this research were all illegal mining workers in Cisarua. The samples were taken using accidental sampling technique with a number of 40 workers and collected by interviews and observation. The measurement of mercury levels in workers hair counted with AAS FIMS by Reverence Recovery Material 100%. The independent variables in this study were age, working period, hours of work and consumption of fish. Meanwhile, the dependent variable was the accumulation of mercury in workers hair samples. The results showed that the average accumulation of mercury in hair samples counted between 2,03 to 9,04 ppm. There are 24 people (60%) suffered mercury poisoning more than 2 ppm. The working period factor (p value = 0.000) correlated with the accumulation of mercury in hair samples of IGM workers. It had a positive correlation with moderate strength (r = 0.552). Multivariate analysis described the model (Accumulation of Mercury = -0.315 + 0.896*working period) with Adjusted R Square 52.6%.

Numerous studies have constructed financial inclusion indexes for Indonesia, using amultidimensional approach. However, there is a problem with the methodology, whichassumes that all the dimensions play the same role in defining financial inclusion,since they are based on equal weighting criteria. This paper aims to obviate concernswith the methodology by developing a more empirically based index, namely, aweighted multidimensional index of financial inclusion based on two-stage principalcomponent analysis. In other words, we endogenize the weights. We find that usage isthe most important dimension in defining financial inclusion in Indonesia, followedby availability and access.

AbstrakSektor pertanian Indonesia seharusnya memperoleh dampak positif dari ASEAN-China Free Trade Agreement (ACFTA). Namun demikian, kinerja sektor pertanian belum menunjukkan peningkatan yang berarti ketika sebagian besar komoditas pertanian telah diturunkan tarifnya melalui tahapan ACFTA. Studi ini meneliti dampak ACFTA terhadap kinerja sektor pertanian Indonesia sebelum dan sesudah ACFTA dengan menggunakan deskriptif analisis. Studi ini juga memprediksi kinerja perekonomian dan kinerja sektor pertanian setelah ACFTA diberlakukan secara penuh menggunakan metode ekonometrik dengan persamaan simultan. Hasil studi ini menunjukkan bahwa kinerja sektor pertanian Indonesia tidak lebih baik dibandingkan dengan sebelum implementasi ACFTA, dan diprediksi akan lebih buruk lagi setelah ACFTA diberlakukan sepenuhnya, akibat dari tingginya tekanan kompetisi dan kekakuan produsen domestik. Peningkatan kualitas infrastruktur domestik, pengembangan riset/teknologi serta penerapan regulasi yang mendukung daya saing merupakan kebijakan yang sangat diperlukan.

Abstract. Nasrudin, Kurniasih B. 2021. The agro-physiological characteristics of three rice varieties affected by water depth in the coastal agricultural land of Yogyakarta, Indonesia. Biodiversitas 22: 3656-3662. Coastal agricultural land has many obstacles of abiotic stress for plant cultivation, including waterlogging, strong wind, and high salt concentration. Therefore, the use of adaptive rice varieties, as well as good land management, are expected to be a solution for rice cultivation in the coastal agricultural land. The objective of this study was to examine the agro-physiological characteristics of three rice varieties planted in coastal agricultural land which were affected by water salinity up to more than 10 dS m-1. This study was conducted from February to July 2017 at Tirtohargo, Bantul District, Special Region of Yogyakarta. The experiment was arranged in a split-plot design, with the depths of sunken-bed as a main plot consisted of 25 cm and 50 cm, and variety as a subplot consisted of IR 64, Inpara 4, and Dendang. The experiment results showed that Dendang had the highest growth and yield in coastal agricultural land compared to Inpara 4 and IR64. The highest value is indicated in plant height, leaf area, proline content, and productivity. The depths 50 cm of sunken-bed increased leaf area and proline content, whereas the depths of 25 cm sunken-bed increased productivity. Dendang showed better agro-physiological activity and had the highest productivity. The depths of 50 cm increased several parameters in agro-physiological characteristics, however, the depths of 25 cm increased grain yield. Among the varieties tested, in salinity, the highest growth and yield variables were shown by Dendang, followed by IR 64 and Inpara 4.

Increased productivity of rice is required to meet the increasing food demand. Utilization of marginal lands, such as saline land is one of the solutions applicable to increase rice production. The objective of this study was to determine the growth and yield of Inpari 29 rice variety planted on raised-bed and different depths of sunken-bed in saline field. This study used the Split Plot Design with two treatments. The depth as the main plot consisted of two depth levels: a depth of 50 cm and a depth of 25; and the planting area field as the subplot that consisted of two levels: raised-bed and sunken-bed. The treatment was repeated three times. The rice planted in sunken-bed showed higher growth than in raised-bed as indicated by the high content of chlorophyll a, chlorophyll b, total chlorophyll, nitrate reductase activity and plant height. The rice planted in the sunken-bed yielded higher than in raised-bed as indicated by higher harvest index and the weight of grain per clump. Rice planted in 25 cm depth showed higher nitrate reductase activity and grain weight per clump than in 50 cm depth.

Drought stress affected growth and decreases rice yield. The use of high yielding varieties and drought tolerance is a strategic step that can be applied during drought stress. The aim of this research was to examine the response of the growth of IPB 4S rice varieties on planting media with drought stress during vegetative phase. The research used a nonfactorial Completely Randomized Design with six levels: field capacity, 10% of field capacity, 20% of field capacity, 30% of field capacity, 40% of field capacity, and 50% of field capacity. The treatments were repeated three times. The growth parameters were plant high, number of tiller, leaf color, leaf area, root length, root dry weight, canopy dry weight, and biomass. The results showed that the drought stress significantly different to leaf area, root length, canopy dry weight, and biomass but were not significantly different to plant height, number of tiller, leaf color, dan root dry weight. Increased of drought stress 30 to 50% of field capacity decreased of leaf area, canopy dry weight, and biomass, but increased root length.

Gross Domestic Product (GDP) is considered as the best measure of economicperformance. However, in Indonesia, the GDP is presented in quarterly aggregate value.As a result, the monthly economic outlook is unknown, and analysis with other monthlyeconomic variables becomes limited. Therefore, this study will disaggregate quarterlyGDP into monthly GDP and its forecasting by using one of the coincident indicatorswhich are monthly Production Index of Large and Medium Manufacturing (industrialproduction index). Disaggregation is done on National GDP data of Indonesia period2000/I to 2016 / IV, whereas forecasting is made on monthly and quarterly GDP 2017.This study uses a combination of the simple linear regression model and ARIMA modelwith some modifications. The disaggregation result indicates that the monthly GDPmoves volatile and has a different pattern between quarters. Also, the monthly GDPdisaggregation and forecasting are proven that can be used by industrial productionindex that becomes a coincident indicator. GDP 2017 shows that the highest quarterlyGDP will have occurred in the third quarter, whereas the highest monthly GDP willhave occurred in June (second quarter). The result of disaggregation can be used furtherto the study of economic outlook will be more comprehensive.

Indonesian Crude Oil Price (ICP) often fluctuates by the shock of world oil prices. Because of its important role, the fluctuations or shocks in ICP will affect Indonesia's macro economy. To overcome this problem, this study analyzes the impact of the crude oil price shocks on Indonesia's macro economy which includes economic growth and the money supply (M2) during 2010-2016 using Vector Error Correction Mechanism (VECM). The results show that short-term fluctuations of ICP have a significant and positive effect on economic growth but have a non-significant effect on the money supply. In the long term equilibrium, ICP have a positive and significant effect to both economic growth and money supply which in line with Impulse Response Function (IRF) and Decomposition of Variance (FEDV) analysis. Given its positive impact, the recent decline in oil prices will harm the Indonesian economy. Therefore, the government needs to reduce its dependence on crude oil exports and accurately predict the crude oil price in the future. PENDAHULUANMinyak merupakan salah satu komoditas yang memiliki peranan penting bagi perekonomian Indonesia. Hampir seluruh sektor perekonomian menggunakan minyak sebagai sumber energi dalam menjalankan aktivitas ekonominya. Sepanjang tahun 2015, Badan Pusat Statistik (BPS) mencatat bahwa Indonesia telah melaksanakan ekspor dan impor minyak mentah masing-masing senilai US$6.479,4 juta dan US$8.063,3 juta yang menunjukkan bahwa minyak mentah aktif diperdagangkan di pasar Internasional. Selain itu, Indonesia yang telah kembali menjadi anggota OPEC menempati urutan ke-22 sebagai negara produsen minyak terbesar di dunia dengan total produksi sejumlah 937.000 barel per hari di tahun 2016 (US EIA, 2017).
