Abstract

Klorofil merupakan faktor utama yang mempengaruhi fotosintesis. Fotosintesis adalah proses perubahan senyawa anorganik (CO2 dan H2O) menjadi senyawa organik (karbohidrat) dan O2 dengan bantuan sinar matahari. Klorofil adalah pigmen utama yang ditemukan dalam kloroplas. Tiga fungsi utama dalam proses fotosintesis, klorofil adalah pemanfaatan energi matahari, pemicu fiksasi CO2 untuk menghasilkan karbohidrat dan menyediakan energi bagi ekosistem secara keseluruhan. Karbohidrat yang dihasilkan dalam fotosintesis diubah menjadi lemak, protein, asam nukleat, dan molekul organik lainnya. Penelitian ini didanai di Taman Pabatu. Waktu penelitian adalah 3 bulan, yaitu dari bulan April - Juni 2018. Penelitian ini menggunakan analisis deskriptif dengan jumlah ulangan 3 pohon yang ditanam pada tahun 2004, 2005, 2006 dengan pengambilan 6 sampel pada tiap daun pohon yang dipelihara berjumlah 9 pohon. , 17, dan 25 per tahun untuk penanaman. Kemudian klorofil pada daun di ukur dengan Clorofil Meter dengan mencari rata-rata klorofil daun.

Abstract

The transportation of Fresh Fruit Bunches (FFB) aims to deliver FFB and loose fruits to the mill in good condition through careful handling and adherence to delivery schedules, ensuring optimal palm oil mill operations. Freshly harvested FFB must be transported immediately for prompt processing. This study evaluates the effectiveness of FFB transportation at PT. Langkat Nusantara Kepong, Bekiun Estate, Division III, located in Langkat Regency, North Sumatra Province. A descriptive analysis with a purposive sampling method was used, collecting primary and secondary data from reliable sources. The results show that cargo rickshaws are more efficient for transporting FFB from the collection point (pasar pikul) to the loading ramp (TPH), carrying an average of 15.3 FFB with an average bunch weight of 114.87 kg per trip within 05:17 minutes, while wheelbarrows transport an average of 14.6 FFB with an average bunch weight of 244.9 kg per trip within 05:31 minutes.

Abstract

Oil palm plantations cannot be separated from harvest workers, where harvest labor has an impact on the yield or quality of the fruit which will later be sold to the public. Of course, special attention needs to be paid to the harvest workforce, such as facilities and infrastructure that support good quality of palm oil products. This research was conducted at PT. Langkat Nusantara Kepong, Kebun Bukit Lawang Division II. This research was carried out in July – August 2022. The method used was quantitative descriptive and assisted by using the SPSS application. There are 5 variables taken, namely X1 (Age), X2 (Education Level), X3 (Work Experience), X4 (Salary), X5 (Support Facilities). The results of this research show that the F test together with the independent variables has a significant effect on the productivity of oil palm harvest workers, while the results of the T test on X4 (Salary) and X5 (Support Facilities) have a significant effect on the productivity of coconut harvest workers. palm oil in Bukit Lawang Plantation Division II, PT. Langkat Archipelago Kepong.
