In the last 15 years, Indonesia palm-cooking oil price tend to increase significantly. The increase of palm-cooking oil price was driven by either its demand or supply. This study aimed to determine factors affecting of demand, supply, and Indonesia palm-cooking oil price. This research used time series data from 1990 to 2014. Simultaneous equation model was performed to analyse demand and supply of palm-cooking oil. The result indicated that income and population significantly influenced demand for palm-cooking oil. These implied that palm-cooking oil is categorized as normal good and staple food in Indonesia. While the price of palm-cooking oil, palm oil production, and real price of CPO Domestic significantly influenced supply of palm-cooking oil.

Industri kelapa sawit menjadi sorotan karena selalu dikaitkan dengan isu deforestasi, kehilangan biodiversitas, peningkatan emisi dan alih fungsi lahan. RSPO (Roundtable on Sustainable Palm Oil) hadir sebagai salah satu label sertifikasi untuk menjamin praktik perkebunan kelapa sawit yang berkelanjutan. Namun sertifikasi RSPO berdampak terhadap peningkatan biaya sehingga memengaruhi kinerja keuangan perusahaan. Selain itu, kinerja keuangan perusahaan dipengaruhi oleh banyak faktor baik internal dan eksternal. Penelitian bertujuan menganalisis pengaruh sertifikasi RSPO dan faktor-faktor lainnya terhadap kinerja keuangan perusahaan kelapa sawit di Indonesia yang diproksi dengan Return on Assets (ROA), analisis  menggunakan Regresi Panel Statis. Penelitian menggunakan data sekunder berupa laporan tahunan periode 2015-2021 dari 15 perusahaan kelapa sawit yang terdaftar di Bursa Efek Indonesia (BEI). Hasil Regresi Panel Statis dengan Fixed Effect Model (FEM) menunjukkan bahwa sertifikasi RSPO berpengaruh positif dan signifikan terhadap ROA. Hasil penelitian menunjukkan bahwa perusahaan yang memiliki sertifikasi RSPO memiliki ROA yang lebih besar dibandingkan perusahaan yang tidak memiliki sertifikasi dengan selisih 2,04%. Faktor lainnya yang berpengaruh positif terhadap ROA, yaitu ukuran perusahaan dan harga CPO internasional. Sedangkan Debt Asset Ratio (DAR) dan Cost of Goods Sold (COGS) berpengaruh negatif terhadap ROA.

<div>Increasing clove export market share in global markets has promising</div><div>potential. The aims of this study are to identify the market structure of clove exporting countries and to measure the level of competitiveness and competitive advantage possessed by each exporting country. This study used time series data of Indonesian, Madagascar, Singapore and Comoro clove exports since 2001-2019. The CR4 method is used to identify the market structure, Revealed Comparative Advantage (RCA) used to measure the level of export competitiveness comparatively and Export Competitiveness Index (ECI) used to identify the competitive advantage of each exporting country. The results of the study stated that the market structure formed leads to an oligopoly market with Indonesia and Madagascar as market leaders. Meanwhile, the level of export competitiveness and competitive advantage possessed by Indonesia tend to increase. To increase the share of Indonesian clove exports can be done by conducting dissemination to clove farmers about cultivation technology. So, the farmers can produce high quality clove.</div>

The aim of the study was to determine effect of local feed on the production and quality of duck eggs in Tanjungpinang, Riau Islands.
