Judul: Consideration of Tapper Factor in the Preparation of Annual Technical Plans (ATP) for Pinus Taps (Pinus merkusii)
Abstrak: Pinus (Pinus merkusii) menjadi tanaman yang diusahakan oleh Perum Perhutani yang memiliki permintaan pasar yang tinggi. Produksi getah Pinus telah diatur setiap tahunnya pada RTT Sadapan. Permasalahan yang dihadapi berupa penyusunan RTT Sadapan yang hanya disusun berdasarkan data potensi pohon. Tujuan penelitian ini mengetahui faktor penyadap melalui kesesuaian POB penyadapan. POB penyadapan dibuat untuk mencapai tujuan perusahaan. Penelitian ini dilakukan di RPH Sugihan pada Januari hingga Februari 2023 menggunakan kuesioner, observasi lapang dan penelusuran dokumen dengan pemilihan sampel berdasarkan kategorisasi kinerja penyadap. Hasil penelitian ini menunjukkan tidak semua penyadap memiliki alat yang sesuai dengan POB penyadapan. Pohon pangkuan penyadap dan tingkat pelaksanaan POB penyadap, kategori kinerja penyadap sangat rendah memiliki kesesuaian terendah dan penyadap kategori kinerja sangat tinggi memiliki kesesuaian tertinggi dengan POB penyadapan. Kategorisasi kinerja penyadap berbanding lurus dengan kesesuaian POB penyadapan dengan demikian faktor penyadap dapat dipertimbangkan dalam penyusunan target RTT Sadapan., Pinus (Pinus merkusii) is a plant cultivated by Perum Perhutani, with high market demand. Pinus sap production has been regulated annually at the ATP of Tapping. The problem faced is ATP Tapping, which is only compiled based on tree potential data. This research aims to find out the tapping factors through the compliance of wiretapping SOPs. Wiretapping SOP is made to achieve company goals. This research was conducted at the Sugihan RPH from January to February 2023 using a questionnaire, eight observations, and document tracing with sample selection based on the performance categorization of tappers. The results of this study indicate that not all tappers have tools that are by SOP wiretapping. The tapper's lap tree and the level of implementation of the tapper's SOP, the very low-performance category of tappers has the lowest suitability, and the tapper's very high-performance category has the highest suitability with the interceptor's POB. The performance categorization of tappers is directly proportional to the suitability of wiretapping SOPs. Thus, the tapping factors can be considered in preparing targets for Tapping ATP.

Judul: Hubungan Perilaku Penyadap Terhadap Kinerja Penyadapan Getah Pinus di BKPH Paninggaran, KPH Pekalongan Timur
Abstrak: Penyadap getah pinus memegang peranan penting dalam kegiatan penyadapan dan mempunyai pengaruh dalam hasil produksi getah pinus di Perum Perhutani. Keterampilan dalam melakukan pekerjaan sesuai standar yang berlaku dapat menentukan hasil kerja. Penelitian bertujuan untuk menjelaskan hubungan karakteristik penyadap terhadap perilaku dan hubungan perilaku penyadap terhadap kinerja. Penelitian dilakukan terhadap 92 responden yang dipilih secara acak. Pengukuran dilakukan dengan menggunakan skala Likert. Hasil penelitian menunjukkan bahwa terdapat hubungan antara usia, hari kerja dan pengalaman kerja terhadap perilaku penyadap. Hubungan perilaku penyadap terhadap kinerja penyadap menunjukkan korelasi positif yang signifikan. Diperlukan monitoring berkala sebagai langkah pendekatan dan observasi masalah yang ada di lapangan untuk membentuk manajemen sumberdaya manusia yang lebih baik. Kata kunci: penyadap pinus, perilaku penyadap, kinerja penyadap, Pine resin tappers have an important role in tapping activities and have an impact on the production of pine resin in Perum Perhutani. Their ability to perform their work according to the applicable standards can determine the results of their work. The study aims to explain the relationship between tappers characteristics and behaviour, and the relationship between tappers behaviour and performance. The study was carried out on 92 randomly selected respondents. Measurements were made using a Likert scale. The results showed that there was a relationship between age, working days and work experience on tappers behaviour. The relationship between tappers behaviour and tappers performance showed a significant positive correlation. Periodic monitoring is needed as an approach and observation of problems in the field to form a better human resource management. Keywords: pine resin tapper, tapper behaviour, tapper performance

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.
