Judul: Palm Oil Seed Production Managemen at  PT Bina Sawit Makmur, South Sumatra
Abstrak: Permasalahan yang sedang dihadapi oleh produsen benih unggul kelapa saat ini adalah tingginya produksi benih putih dan benih kecil yang kurang diminati oleh konsumen. Mengingat tingginya jumlah benih putih dan benih kecil dalam setiap tandan benih, maka penting halnya untuk dilakukan penelitian untuk mengamati faktor-faktor apa saja yang menyebabkan tingginya jumlah benih abnormal ini dalam tandan benih kelapa sawit. Kegiatan magang telah dilakukan di PT Bina Sawit Makmur, Sumatera Selatan selama empat bulan dari Februari 2023 hingga Mei 2023. Kegiatan magang mencakup seluruh kegiatan budidaya kelapa sawit dari segi teknis dan manajerial seperti teknisi, mandor, dan asisten. Tujuan khusus magang ini untuk mengetahui pengaruh frekuensi panen tandan benih terhadap mutu fisik benih kelapa sawit untuk mengatasi masalah tingginya produksi benih kecil dan benih putih kelapa sawit yang kurang diminati oleh konsumen. Pengamatan dilakukan terhadap beberapa frekuensi panen per tahun dan diperoleh hasil semakin tinggi frekuensi panen tandan benih dalam setahun maka perolehan benih dan kualitas fisiknya juga akan menurun signifikan., The most current issue faced among the coconut oil palm seed producers is the high production of white and small seeds that are less desirable to consumers. Given the high number of white seeds and small seeds in each seed bunch, it is important to conduct research to observe what factors cause the high number of abnormal seeds in oil palm seed bunches. Internship activities have been carried out at PT Bina Sawit Makmur, South Sumatra for four months from February 2023 to May 2023. The internship covered all oil palm cultivation activities from technical and managerial aspects such as technicians, foremen, and assistants. The specific objective of this internship is to determine the effect of seed bunch harvesting frequency on the physical quality of oil palm seeds to overcome the problem of high production of small seeds and white seeds of oil palm that are less desirable to consumers. Observations were made on several harvesting frequencies per year and it was found that the higher the harvesting frequency of seed bunches in a year, the seed yield and physical quality will also decrease significantly.

Abstrak: Kebun induk kelapa sawit merupakan kebun penghasil benih unggul kelapa sawit. Terdapat pekerjaan isolasi bunga jantan dan betina, polinasi bunga betina, panen tandan buah polinasi dan bunga jantan. Magang mempelajari pengelolaan kebun induk secara umum dan secara khusus sistem kerja yang digunakan, kapasitas panen tanda polinasi, dan pengaruh konsentrasi formaldehid terhadap viabilitas polen. Kegiatan magang dilaksanakan di Kebun Surya Adi, PT Binasawit Makmur, Ogan Komering Ilir, Sumatera Selatan berlangsung dari Februari hingga Juni 2023. Pelaksanaan magang pada tingkatan level teknisi, mandor, dan asisten. Terdapat perbedaan phytomer masing-masing bunga, sehingga umur bunga pada satu pokok pasti berbeda. Isolasi bunga dapat dilakukan satu bunga pokok-1 hari-1 untuk menghindari bunga terlewat diisolasi. Pekerjaan polinator dapat dipisah dengan pemasangan label dan jaring untuk mengurangi beban polinator saat tingkat polinasi tinggi. Perbedaan kapasitas panen pokok tinggi dan pokok pendek dapat dipisahkan melalui perbedaan premi panen. Pengamatan pengaruh formaldehid terhadap daya hidup polen menggunakan formaldehid dengan konsentrasi 1%, 4%, 6%, 10% dan kontrol 0%. Tidak ada beda nyata antar perlakuan tetapi perlakuan formaldehid membunuh semua polen (Viabilitas 0%) dibandingkan kontrol. Penggunaan formaldehid pada konsentrasi 1% sudah efektif membunuh polen., Seed garden is a field that produces superior oil palm seeds. The work involves isolating male and female flowers, pollinating female flowers, harvesting pollinated fruit bunches and male flowers. Interns study of management seed gardens in general and specifically the work system used, the harvesting capacity of pollination marks, and the effect of formaldehyde application on pollen viability. Internship activities were carried out at the Surya Adi Plantation, PT Binasawit Makmur, Ogan Komering Ilir, South Sumatra from February to June 2023. The internship was done at the level of technician, foreman, and assistant. There are differences in the phytomer of each flower, therefore each flowers in the tree must be indifference stage. Flower isolation can be done one flower per tree per day to avoid missed flowers being isolated. Pollinator work can be separated by labeling and netting to reduce the burden on pollinators when the pollination rate is high. The difference in harvesting capacity of tall trees and short trees can be separated through the difference in harvest premiums. Observation of the effect of formaldehyde on pollen viability using formaldehyde with concentrations of 1%, 4%, 6%, 10% and control (0%). There was no significant difference between treatments, but the formaldehyde treatment killed all pollen (0% viability) compared to the control. The use of formaldehyde at a concentration of 1% is effective in killing pollen.

Judul: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
