Abstract

Trichoderma sp. helps provide nutrients for plants by accelerating the decomposition of organic compounds. This study aims to determine the growth of Pontianak siam orange seedlings on peat soil with the provision of T. harzianum inoculant (R3). The research design used a completely randomised design (CRD) with five treatments, each with four replications. The observation variables were plant height, number of leaves, wet weight and dry weight of plants. Based on ANOVA test, the application of T. harzianum inoculant (R3) had no significant effect on plant height and number of leaves, but had a significant effect on wet weight and dry weight of plants. Giving 50 g of T. harzianum inoculant (R3) was the best treatment for the growth of Pontianak siam orange seedlings.

Abstract

Improving teachers' competence is one of the objectives of the subject teachers' group (MGMP). One important competency that teachers is the ability to publish scientific papers. Statistical data analysis and data visualisation are important components in scientific publications, but these two things are challenging. This program aims to improve the knowledge and skills of teachers who are members of MGMP Biology SMA in Pontianak, in statistical data analysis and data visualisation through training in the use of R and RStudio (Posit). In this course, we delivered presentations and demonstration of the use of R and RStudio. At the end of demonstration activities, each participant carried out independent completion of the use of R and RStudio. This training activity was attended by 16 participants from several high schools in Pontianak. The results showed that there was an increase in the knowledge and skills of the participants based on the results of the pre-test and post-test assessments.

Abstract

Orchids are plants that have been cultivated because they have high economic value. Orchid cultivation is also done to maintain its sustainability. Orchid cultivation requires special knowledge to produce good growth. This educational activity aims to provide knowledge and skills about orchid cultivation for Rasau Jaya Kubu Raya youth group. The method of implementing this activity includes preparation, implementation, and evaluation. Preparation includes coordination with partners regarding the schedule, location, tools, and materials needed. The implementation of activities consists of the delivery of material on the prospects of orchid cultivation, the stages of cultivation, demonstrations, and practices of planting and crossing orchids. Evaluation was carried out by filling out a questionnaire. The knowledge and skills of participants in this educational activity increased from 70.00% who did not know to 40% who knew and 60.00% who were very knowledgeable through the delivery of materials, demonstrations, and practices. This training was beneficial (70.00%) and inspiring (100%). Participants hope that this educational activity can be practiced by themselves and inspire them to open an orchid cultivation business.

Abstract

Tukong chicken, also known as rumpless chicken due to the absence of a tailbone, is one of the indigenous chicken breeds in Indonesia currently at risk of extinction. Due to its scarcity, genetic information on the Tukong chicken remains limited, and its potential has not been fully explored. Therefore, this study aimed to determine the genetic external characteristics of the Tukong chickens. Data were collected from 205 chickens (52 males; 153 females) raised in Landak and Bengkayang Regency, West Kalimantan. The varieties are based on feather color, plumage color, feather pattern, feather flicker, comb shape, and shank color. The data were used to analyze the rate of the original gene, the frequency of autosomal genes, sex-linked genes, feather pattern, introgression rate, gene frequency, and expected heterozygosity. The majority of the Tukong chickens had colored feathers (88.78%), columbian feather type (47.80%), plain feather pattern (61.46%), silver feather flicker (54.63%), yellow-white shank (62.44%), and pea comb (77.07%), which were controlled by ii, ee, bb, SS, IdId, and P_ genes, respectively. The introgression rate from exotic breeds into Tukong chicken is 53.2%, with the original gene at 46.8%, while the average expected heterozygosity was 0.416±0.025, indicating a high level of genetic diversity of the traits. This observed variation in qualitative morphological characteristics might benefit both the conservation and utilization of the Tukong chicken.

Abstract

Buah naga dapat diperbanyak secara generatif menggunakan biji. Salah satu cara yang dapat digunakan untuk mempercepat proses perkecambahan adalah dengan merendam biji menggunakan zat pengatur tumbuh (zpt). Ekstrak tomat merupakan zpt yang dapat mempercepat perkecambahan biji. Tujuan penelitian ini adalah untuk mengetahui pengaruh konsentrasi ekstrak tomat dan lama waktu perendaman terhadap perkecambahan biji buah naga. Bahan yang digunakan pada penelitian ini, yaitu aquades, biji buah naga (Hylocereus polyrhizus), ekstrak buah tomat (Solanum lycopersicum L. var. intan). Penelitian ini merupakan penelitian eksperimental dengan menggunakan Rancangan Acak Lengkap (RAL) faktorial yang terdiri dari dua faktor, yaitu konsentrasi ekstrak tomat dan waktu perendaman. Faktor pertama, konsentrasi ekstrak tomat (T), yaitu terdiri dari Kontrol (T0), 4% (T1), 6% (T2), 8% (T3), dan 10% (T4). Faktor kedua lama perendaman (P), yaitu Kontrol (P0), 6 Jam (P1), 12 Jam (P2), 24 Jam (P3), 48 Jam (P4). Penelitian dilakukan di Laboratorium Biologi Umum, Jurusan Biologi, Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Tanjungpura, Pontianak. Penelitian dilakukan pada bulan Agustus hingga September 2022. Hasil penelitian menunjukkan bahwa waktu perendaman 48 jam merupakan waktu terbaik pada parameter persentase perkecambahan (74,8%), waktu muncul kecambah (3,96 hst), dan panjang radikula (0,29 cm). Konsentrasi ekstrak tomat 10% merupakan konsentrasi terbaik pada parameter waktu muncul kecambah. Kombinasi konsentrasi ekstrak tomat dan lama waktu perendaman memberikan hasil tidak berpengaruh nyata terhadap semua parameter pengamatan.
