TEXTURE CHARACTERIZATION OF THE COPPER PRODUCED BY ECAP PROCESS USING NEUTRON DIFFRACTION TECHNIQUE

TEXTURE CHARACTERIZATION OF THE COPPER PRODUCED BY ECAP PROCESS USING NEUTRON DIFFRACTION TECHNIQUE. Texture and hardness characterization have been carried out on market copper samples that have gone through the equal channel angular pressing (ECAP) process. Neutron diffraction technique had been used for obtaining an average crystalline texture in a particular volume non destructively to the sample. The ECAP process is carried out once (1 pass) with some parts that have been plastically deformed and some parts that have not been deformed. Crystalline texture and hardness were observed in the deformed and non-deformed parts. Initial characterization was carried out by X-ray diffraction (XRD) followed by measurement of crystal texture using the neutron diffraction technique, while hardness was tested using the Vickers method. Rod-shaped sample with a diameter of 10 mm. Texture observations were performed at the center of the sample with a neutron beam limiting slit of 5x5 mm2 . There was an increase in hardness in the deformed position compared to the undeformed one. The texture that occurs is in the form of fibers with different directions and indexes, sequentially as follows: position 1, [111] of 4.96 m.r.d., position 2, -[111] of 1.86 m.r.d. and position 3 [010] of 2.44 m.r.d. , position 4 orientation is distributed on [011], [013], [115], [235] fibers with a texture index range of 1.07–1.33 m.r.d

Implementasi Model Pembelajaran Kooperatif Think Pair Share untuk Meningkatkan Hasil Belajar Siswa

This study aims to improve the science learning outcomes of class IX students in through application of the Think Pair Share (TPS) cooperative learning model. This type of research is a type of Classroom Action Research (PTK) which is carried out in 2 cycles. Where each cycle consists of 3 meetings. The research was conducted in September - October 2022 with the research subjects being class IX students of SMP N 2 Jetis Ponorogo. Data collection techniques used in this study are test. The test are essay test with a total of 10 items. The data obtained was then analyzed descriptively to see an increase in student learning outcomes. Based on the analysis, it is known that student learning outcomes have increased. This is evidenced by an increase in the class average score which was initially only 60.2 in the initial conditions to 86.3 at the end of cycle 2. Based on these data it can be concluded that the science learning outcomes of class IX students of SMP N 2 Jetis Ponorogo can be improved through the application of the Think Pair Share cooperative learning model

Effectiveness Model of the Nature Tourism Based Community Forest Program Implementation in Bangka Tengah District

Nature tourism-based community forest (NTCF) is one form of community forest utilization in Bangka Tengah District. In its implementation, the effectiveness of this program is relatively different among community forest groups. This difference of effectiveness level could be influenced by various factors. Therefore, identification of these factors needs to be taken into consideration in making decisions to improve the effectiveness of the intended program. This study aims to identify the influencing factors and efforts to improve the effectiveness of NTCF implementation. The method used is the structural equation modeling and qualitative analysis. The results of the study showed that the factors that influence the effectiveness of the implementation are the attitude of the government, attitudes of community leaders, forestry extension human resources, attitudes of non-governmental organizations and the level of education of the community. For these reasons, the efforts should be conducted to achieve the effectiveness of the NTCF are to increase the support of community leaders, NGOs, and the government, increase the capacity of human resources for forestry instructors and provide education and training for the groups with relatively low levels of education. Keywords: community forest, natural tourism, structural equation modeling, utilization

Pendampingan Pemanfaatan Teknologi Informasi sebagai Upaya Digitalisasi Produk pada UMKM Omah Batik Sukun

Omah Batik Sukun is one of the MSMEs in batik production. This MSME experienced a decline in sales due to the influence of the Covid-19 pandemic in 2020 and 2021. The pandemic for 2 years has caused orders and of course batik production to decrease. Based on this, the service team provides assistance in the use of information technology to increase sales of batik product. Digital marketing is used to promote and introduce to the wider community about batik product. The method used in this service is the method of consultation and science and technology diffusion. This method consists of 3 processes, namely pre-production, production and post-production processes. This service was carried out for 2 months, in January and February 2022. The result of this service activity was a video profile production which was uploaded to YouTube, an Instagram account containing Omah Batik Sukun MSME products and a digital catalogue. The impact of implementing this activity is that there is an increase in the knowledge of Batik Sukun MSME managers regarding digital marketing, an increase in sales of 30%, the number of buyers increasing to 3 cities, and the community starting to become familiar with this batik product, around 30% are starting to recognize this batik. ABSTRAKOmah Batik Sukun merupakan salah satu UMKM yang bergerak di bidang produksi batik. UMKM ini mengalami penurunan penjualan karena pengaruh pandemi covid-19 di tahun 2020 dan 2021. Pandemi selama 2 tahun ini menyebabkan pesanan dan juga tentu saja produksi batik berkurang. Berdasarkan hal tersebut, tim pengabdi melakukan pendampingan dalam pemanfaatan teknologi informasi untuk meningkatkan penjualan batik ini. Penggunaan digital marketing dimanfaatkan untuk mempromosikan sekaligus memperkenalkan ke masyarakat luas mengenai batik ini. Metode yang digunakan dalam pengabdian ini adalah metod konsultasi dan difusi iptek. Metode ini terdiri dari 3 proses, yaitu proses pra produksi, produksi dan pasca produksi. Pengabdian ini dilaksanakan selama 2 bulan, yaitu pada bulan Januari dan Februari 2022. Hasil dari kegiatan pengabdian ini adalah menghasilkan satu video profil yang sudah diunggah di youtube, akun Instagram yang berisi produk UMKM Omah Batik Sukun dan katalog digital. Dampak dari pelaksanaan kegiatan ini adalah adanya peningkatan pengetahuan pengelola UMKM Batik Sukun terkait digital marketing, peningkatan penjualan sebesar 30%, jumlah pembeli meningkat menjadi 3 kota, dan mulai dikenalnya produk batik ini di masyarakat yaitu sekitar 30% mulai mengenal batik ini
