Abstract

This research introduces branching processes as a stochastic process for estimating the number of the population of individuals at any generation “n”. One of the most interesting applications of branching processes is calculating the probability of eventual extinction. In probability theory, a branching process is a Markov chain that models a population in which each individual in generation “n” produces some random number of individuals in generation n + 1, according to a fixed probability distribution that does not vary from individual to individual. Branching processes are used to model reproduction. A central question in the theory of branching processes is the probability of ultimate extinction, where no individuals exist after some finite number of generations. Keywords: branching process, stochastic process, discrete time markov chain

Abstract

This activity is a collaboration between the community service team of the University of Indraprasta Graduate School (Unindra) and the Centre for the Development of Educational Competence, Education and Research (P2KPTK2) in West Jakarta. Pkm activities were carried out online through zoom meetings on 1-5 August 2022 and expected to provide insight to low-level elementary school teachers in the work area of P2KPTK2 West Jakarta in terms of the use of innovative learning models in thematic learning in schools. The methods used in this activity are lectures, questions and answers and practice making educational games based on the Internet. After the community service, there is an increase in the value of the post-test results or a change between the lowest, highest, and rare values in general. At the lowest level there is a decrease of 10 points while at the highest there is no increase. The ratio increased by 32.97 points. Generally speaking, the rate of improvement in competence after the community service was 27.45%. The school is expected to provide guidance on the importance of this activity for teachers to improve competence. In addition, teachers should also be aware of the importance of improving themselves through such training to adapt to the demands of the implementation of education in the era of technology as it is now.

Abstract

Guru sebagai tenaga pendidik diharapkan untuk terus-menerus meningkatkan kemampuan profesionalnya, terutama dalam bidang pengajaran, tidak terkecuali guru SD. Namun masih ada guru SD yang menggunakan pembelajaran konvensional dalam menyampaikan materi pembelajaran ke peserta didik. Akibatnya, peserta didik kurang dapat mengembangkan kemampuan kognitif, afektif, dan psikomotoriknya. Salah satu pembelajaran yang dapat mengatasi hal tersebut adalah Open ended berbasis APOS. Open-Ended merupakan jenis pembelajaran di mana guru memberikan suatu situasi masalah kepada peserta didik yang solusi atau jawaban masalah tersebut dapat diperoleh dengan berbagai cara. Untuk mengimplementasikan pembelajaran tersebut, diperlukan tahapan pembelajaran. Dalam hal ini, tahapan pembelajaran Open-Ended berbasiskan APOS. APOS adalah suatu teori konstruktivisme tentang bagaimana peserta didik mengkonstruksi konsep melalui 4 hal, yaitu Aksi (Actions), Proses (Processes), Objek (Objects), dan Skema (Schema). Ke-4 hal tersebut dilakukan melalui siklus ACE, yaitu aktivitas (Activities), diskusi kelas (Class discussion), dan latihan soal (Exercises). Adapun hasil dari kegiatan pengabdian kepada masyarakat ini adalah ternyata kegiatan ini mampu memberikan solusi alternatif untuk mengembangkan kemampuan dan disposisi peserta didik di tingkat SD melalui implementasi pembelajaran Open ended berbasis APOS.

Abstract

The Community Partnership Empowerment (PKM) program was conducted with the “Giat Bakti Lestari” Farmer Group in Cibadung Village, Gunung Sindur, Bogor. Partners faced two main problems: low banana harvest quality caused by Fusarium wilt disease and the presence of idle, unproductive land. As a solution, the PKM team introduced banana propagation using tissue culture technology through socialization, training, and mentoring. This method offers several advantages over conventional propagation, including faster cultivation, mass production, disease-free seedlings, and genetic uniformity. However, partners had no prior exposure to tissue culture technology. Thus, the PKM activity focused on equipping farmers with skills in household-scale tissue culture techniques and providing simple facilities to support sustainable seedling production. By engaging in this program, the farmer group is expected to gain essential knowledge and practical skills, enabling them to independently manage tissue culture propagation. This initiative not only addresses crop loss due to disease but also promotes the use of modern agricultural practices to maximize land productivity. The activity ultimately aims to foster self-reliance among farmers and contribute to the development of innovative an sustainable farming in the village.
