Judul: Manajemen Kelapa Sawit (Elaeis guineensis Jacq) Di Sekunyir Estate Minamas Plantation Kalimantan Tengah
Abstrak: Kelapa Sawit (Elaeiss gueenensis Jacq) merupakan penghasil minyak nabati penting di Indonesia. Produktivitas kelapa sawit dipengaruhi berbagai faktor diantaranya adalah manajemen pemanenan. Penelitian ini mempunyai tujuan khusus yaitu mempelajari dan memahami manajemen pemanenan kelapa sawit, serta menganalisis faktor-faktor yang mempengaruhi efektivitas dan efisiensi pemanenan kelapa sawit. Pengumpulan data dilakukan dengan metode langsung dan tidak langsung untuk mendapatkan data primer maupun data sekunder. Pengamatan di lapang dilakukan dengan mengikuti delapan pemanen pada sistem Division of Labour (DOL) dan empat tim panen pada system 1 Cutter and 2 Carrier ( C1R2). Perubahan sistem panen dari sistem DOL menjadi sistem C1R2 memiliki dampak yang baik terhadap manajemen panen serta produktivitas dari tim panen. Sistem C1R2 memiliki hasil 5-7% lebih tinggi dari sistem DOL dalam memperoleh buah matang dan memiliki jumlah buah busuk lebih sedikit yaitu sekitar 2,6% dibandingkan sistem DOL yang mencapai 8%., Palm oil (Elaeiss gueenensis jacq) is an important vegetable oil in Indonesia. Palm oil productivity is influenced by various factors including harvest management. This research has specific objectives to be achieved, namely studying and understanding the management of palm oil harvesting, and analyzing the factors that influence the effectiveness and efficiency of palm oil harvesting. Data collection obtained by direct and indirect methods to find primary and secondary data. Field observations were conducted by following 8 harvesters on the Division of Labour (DOL) system and 4 harvest teams on the 1 Cutter and 2 Carrier (C1R2) system. The conclussion of this research is the changing the harvest system from the DOL system to the C1R2 system has a good impact on crop management as well as the productivity of the harvest team. The C1R2 system has a yield of 5-7% higher than the DOL system in obtaining ripe fruit and has a fewer number of rotten fruits which is around 2.6% compared to the DOL system which reaches 8%.

Judul: Manajemen Panen Kelapa Sawit (Elaeis guineensis Jacq.) di  Kebun Cikasungka Distrik Jawa Barat Banten KSO PTPN III
Abstrak: Kegiatan magang dilaksanakan di Kebun Cikasungka Distrik Jawa Barat Banten KSO PTPN III bertujuan untuk mengetahui dan mempelajari manajemen dan teknis pemanenan kelapa sawit di Kebun Cikasungka. Data pengamatan dianalisis secara deskriptif dan kuantitatif menggunakan persentase dan rata-rata. Manajemen panen kelapa sawit di Afdeling 1 Kebun Cikasungka secara umum sudah berjalan dengan cukup baik terlihat dari beberapa aspek seperti ketersediaan tenaga kerja panen di Afdeling 1 sudah memadai. Rata-rata fruit set sebesar 75,06% dan rata-rata fruit to bunch 69,8%. Beberapa aspek belum optimal sehingga perlu ditingkatkan. Rata-rata kapasitas panen dibawah standar RKAP. Faktor yang paling berpengaruh terhadap kapasitas panen adalah jam kerja karyawan. Produksi harian yang diperoleh masih belum mampu mencapai taksasi produksi dengan persentase terhadap taksasi 82,42%. Penggunaan alat pelindung diri (APD) pemanen pada dua kemandoran belum dilakukan secara maksimal., The internship activities were carried out at Cikasungka Estate, West Java Banten District, under the management of KSO PTPN III. The purpose was to understand and learn the management and technical aspects of oil palm harvesting at Cikasungka Estate. Observation data were analyzed descriptively and quantitatively using percentages and averages. Overall, the oil palm harvesting management in Division 1 of Cikasungka Estate has been operating quite well, as evident from various aspects such as the availability of harvest labor in Division 1, which is sufficient. The average fruit set is 75.06%, and the average fruit-to-bunch ratio is 69.8%. However, there are some aspects that are not optimal and need improvement. The average harvesting capacity falls below the RKAP standard. The most influential factor on harvesting capacity is employee working hours. The daily production obtained has not yet been able to reach the production target, with a percentage of 82.42% of the target. The use of personal protective equipment (PPE) by harvesters in two sectors has not been maximized.

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
