Abstract

Form factors and volume models are often be used in the estimation of tree volumes. However, a few studies have developed and evaluated the accuracy of form factors and volume models for estimating tree volumes of community forests. This study aimed to formulate form factors and volume models and assess their prediction accuracy for estimating tree bole volumes of mahogany at community forests in Central Java. This study used 120 sample trees with diameters of 6–38 cm to formulate artificial and absolute form factors and to develop tree bole volume models. These form factors coupled with bole height and total height were used in simple volume equations. Regression analyses were used to develop volume models using the diameter and total height as predictors. The simple volume equations and volume models' prediction accuracy was evaluated using a cross-validation dataset and independent dataset (30 sample trees). The artificial form factor (0.68 ± 0.11) of mahogany, which was higher than the absolute form factor (0.46 ± 0.09), provided accurate estimates of tree bole volumes when it was used with the bole height instead of the total height. The volume model that uses diameter and total height produced the most accurate estimates, while the volume model that uses diameter alone provided the most practical yet reliable tool for estimating tree bole volumes of mahogany. The results of this study are useful for improving community forest management.

Abstract

Tujuan penelitian adalah: 1) Meningkatkan keaktifan siswa, dan 2) Meningkatkan hasil belajar. Prioritas pemecahan masalah yang diterapkan dalam penelitian ini adalah dengan menerapkan model pembelajaran kooperatif tipe STAD Penelitian ini dilaksanakan dalam 2 siklus. Tiap siklus terdiri perencanaan, pelaksanaan, observasi, dan refleksi. Indikator keberhasilan pada penelitian ini adalah 90% prestasi belajar siswa lebih dari KKM yang ditentukan yaitu 65. Berdasarkan hasil penelitian dapat disimpulkan bahwa model pembelajaran kooperatif tipe STAD dapat meningkatkan kualitas pembelajaran ditunjukkan dengan meningkatnya keaktifan siswa selama proses pembelajaran, dan meningkatkan hasil pembelajaran ditunjukkan dengan meningkatnya persentase ketuntasan belajar. Peningkatan prestasi belajar siswa terjadi dengan meningkatnya nilai rata-rata kelas siswa dari 61,5 menjadi 78,5. Dan meningkatnya persentase ketuntasan dari 42,4 % menjadi 100 %.

Abstract

This research aims to describtion how the implementation of the Problem Based Learning (PBL) teaching model can improve the learning outcomes of first-grade students in mathematics at an elementary school. The method used in this research is Classroom Action Research (CAR). The average mathematics learning scores of the students were observed, starting from the pre-cycle exam where the average score was 58.6%, with 43.47% or 10 students scoring below the Minimum Mastery Criteria (KKM). After the first cycle, it was observed that the average score of the students increased to 66.8%, with 73.9% of the students achieving the KKM and 26.09% or 6 students scoring below the KKM or not yet achieving it. After the second cycle, the average score of the students further increased to 78.73%, with 91.29% or 21 students achieving the KKM, and 8.70% or 2 students scoring below the KKM or not yet achieving it in mathematics. Based on these results, it can be concluded that the implementation of the Problem Based Learning (PBL) teaching model can improve the learning outcomes of first-grade students at SDN Lowokwaru 3 Malang.

Abstract

Tobacco cultivation in Tejorejo Village is one of the community's main efforts to improve the village economy. This research uses a qualitative descriptive approach to analyze the challenges faced in tobacco cultivation and their impact on the economy of local communities. The challenges found include technical limitations due to climate change which affects the quality and quantity of harvests. Apart from that, fluctuations in tobacco prices on the market which are influenced by external factors such as government policy and global economic conditions also increase the instability of farmers' income. However, tobacco cultivation has a positive impact in encouraging village infrastructure development and attracting investment. Although progress in the tobacco farming sector can encourage rural infrastructure development and attract investment, over-reliance on tobacco as the sole source of income carries major risks, including economic uncertainty and the potential for crop failure which can impact the village economy as a whole.

Abstract

Abstract. The purpose of this research is to apply the teams games tournament (TGT) model in learning activities which is expected to be able to increase the motivation and learning outcomes of students in grades X-5 which are relatively low. The research method used is classroom action research (PTK). Using two cycles through four steps, namely planning, implementation, observation, and reflection. This research in data collection uses observation, documentation, and test techniques. The results of this study show that before the action was taken, only 12 students achieved a score above 70 with an average of 60.2 and a completion percentage of 31.55% which shows a very poor category. However, after the implementation of the action in the first cycle, there were 19 students who achieved a score above 70 with an average of 68.8 and a completion percentage of 50% which increased by 19.5% compared to before. Furthermore, in the second cycle there were 33 students who achieved a score above 70 with an average of 83 and a completion percentage of 86.8%, which increased by 36% compared to the first cycle. In addition, students also become more motivated to be active during learning activities so that it also affects learning outcomes. Thus, the application of the TGT model has proven to be successful in increasing the motivation and learning outcomes of PAI class X-5 at SMA Negeri 1 Tambakboyo.
