Abstract

Tepurang (Momordica cochinchinensis) memiliki potensi besar dalam bidang farmasi dan pangan, namun keterbatasan bibit dan rendahnya tingkat perkecambahan biji menghambat perbanyakannya. Kultur jaringan menjadi alternatif dalam pelestarian dan perbanyakan tanaman ini, terutama melalui induksi kalus. Penelitian ini bertujuan untuk mengevaluasi pengaruh kombinasi Benzylaminopurine (BAP) dan Indole Acetic Acid (IAA) terhadap induksi kalus dari batang muda M. cochinchinensis secara in vitro. Eksplan berupa batang muda ditanam pada media Murashige & Skoog (MS) dengan kombinasi BAP dan IAA dalam berbagai konsentrasi. Hasil penelitian menunjukkan bahwa perlakuan dengan kombinasi ZPT mampu menginduksi pembentukan kalus dengan warna putih dan tekstur friable setelah 2 minggu subkultur. Temuan ini diharapkan dapat berkontribusi dalam pengembangan metode perbanyakan M. cochinchinensis secara in vitro untuk mendukung konservasi dan pemanfaatannya dalam bidang bioteknologi.

Abstract

There are numerous complex issues that can affect the quality of education in Indonesia. One of them is the low quality of learning and the perceived monotony. In the face of these challenges, teachers and lecturers, as agents of change, must continue to innovate. This writing is based on the partnership program between lecturers from Teacher Training and Education College (LPTK) and teachers from State Senior High School 2 Limboto, involving four biology teachers, the school principal, and one lecturer. The program aims to create interactive and effective biology learning for students. The proposed solution from this program is the implementation of Lesson Study for Learning Community (LSLC), consisting of three stages: Planning, implementation, and reflection, as a form of collaborative effort between lecturers and teachers in designing biology lessons. LSLC activities are conducted in three cycles with three Open Classes. Based on the completed stages, it can be concluded that the collaboration between lecturers and teachers through LSLC activities is highly beneficial and has an extraordinary impact on improving the quality of education. The collaboration between lecturers and teachers in each stage of LSLC activities demonstrates a tangible commitment to the education sector. Therefore, it is expected that a continuous collaboration with universities as school partners can be established.

Abstract

Bihe Village is one of the villages in Asparaga District, Gorontalo Regency, which is a center for coconut production. The abundant potential of coconut plants has yet to be utilized optimally by the people of Bihe village. Coconuts are only produced as copra, or coconuts are sold whole, without processing. Coconut plants have many derivative products, such as virgin coconut oil (VCO) and coconut peat. This problem prompted the implementation of socialization, training, and assistance in making VCO and Cocopeat for the Bihe village community. The aim is to increase the community's insight and skills regarding the diversification of coconut products so that they can provide additional income, which can improve the economy in Bihe Village. The training method is the Participatory Action Research (PRA) method, which involves the active role of the Bihe village community. The stages carried out are analysis of the actual conditions of society, planning, action, observation, and reflection. This method is carried out to provide an understanding of a) the weaknesses they have, b) the community's desire to overcome their shortcomings and weaknesses, c) together with the community to develop strategies and methods to solve the problem, and d) help the community overcome, solve, and find a way out. Forty participants attended this training and mentoring. After implementing the empowerment program, the post-test results showed that 62.5% of the community gave an excellent assessment, and 37.5% gave a good assessment of the usefulness of this activity program. Furthermore, 72.5% of participants were motivated to open a new coconut commodity business.

Abstract

Momordica cochinchinensis, locally known as Dumbaya in Gorontalo Province, is a traditional medicinal plant with underutilized potential due to the extremely hard morphology of its seed coat. This physical barrier limits the penetration of water, air, and nutrients, thereby reducing the success rate of seed germination and plant propagation. The challenge of propagating plants that are difficult to reproduce sexually, such as dumbaya, can be addressed through various approaches, one of which is asexual reproduction using tissue culture techniques. This study aims to address propagation constraints by applying tissue culture techniques supplemented with Plant Growth Regulators (PGRs), specifically BAP (Benzyl Amino Purine) and NAA (Naphthalene Acetic Acid), which are critical factors in successful in vitro plant regeneration. The combination of Benzyl Amino Purine (BAP) and Naphthalene Acetic Acid (NAA) is a commonly used Plant Growth Regulator (PGR) for inducing callus formation and organogenesis, where BAP is effective in stimulating shoot formation, while NAA plays a role in root induction. The research employed an experimental method using a Completely Randomized Design (CRD) with five treatment levels: H0: MS + 0 ppm NAA + 0 ppm BAP; H1: MS + 1.5 ppm NAA + 0.5 ppm BAP; H2: MS + 3.0 ppm NAA + 0.5 ppm BAP; H3: MS + 1.5 ppm NAA + 1.0 ppm BAP; and H4: MS + 3.0 ppm NAA + 1.0 ppm BAP. Each treatment was replicated three times. The results showed that treatment H1 produced the earliest callus formation, with an average callus initiation time of 7 days after planting.

Abstract

Banana (Musa spp) is a tropical fruit plant that has many benefits and important roles for the community. This study aims to provide information on the morphological characteristics of bananas in the Gorontalo Province and their phenetic relationships. This study uses a descriptive method to describe the diversity of morphological characters of bananas (Musa spp) with data collection using a survey study method (exploration) which is carried out by tracing or exploring the location of the Gorontalo Province, purposive sampling (Purposive Stratified Sampling) by seeing and observing directly the morphological characters of bananas (Musa spp). Data analysis using the Unweighted Pair Group with Mean of Arithmetic (UPGMA) method with the Gower Genelar Similarity Coeffiicient formula in the MVSP (Multi-Variate Statistical Package) v.3.1 computer program. The results of the study showed that there were 4 types of bananas found in the Gorontalo Province which showed unique morphological variations, namely Kepok Bananas have the characteristic of quite large leaf morphology, Abati Bananas have a unique yellowish color, Green Butota Bananas have morphological characteristics with very thick fruit and Wild Bananas have characteristics with a large number of stones. Based on the results of the clustering, 2 main groups were formed which separated at a cosiness of 0.643 (64.3%) found between Abati Bananas, Green Butota, and Wild Bananas, while Kepok Bananas showed a very distant relationship with a cosiness value of 0.482 (48.2%). The results of this study have the potential to support the preservation of local varieties and support the sustainable genetics management through the identification of varieties that are tolerant to salinity and drought.
