Abstract

The area of RW 01 Rawamangun, Pulogadung District, East Jakarta does not have an allocation of open land, so there is a minimum of green yards. The technology introduced in this community service activity is the cultivation of family medicinal plants in yards using the verticulture method. The purpose of this community service activity is to convey information about the cultivation of family medicinal plants through lectures, discussions, and direct practice of cultivating family medicinal plants in yards using the verticulture method. Evaluation of participants' knowledge improvement was carried out by pre- and post test after counseling and cultivation practices. Skills participants are carried out when evaluating the practice of cultivating medicinal plants in their yards. The results of the activity showed an increase in basic knowledge regarding the types, benefits, and techniques of cultivating family medicinal plants from technology. Family medicinal plant service activity is classified as successful and beneficial, due to increased knowledge more than 60 in average test scoring. The skills evaluation showed that some residents were able to plant and maintain family medicinal plants on a narrow plot of land using the proper verticulture method. The results of the cultivation of these medicinal plants, apart from being one of the real actions of plant greening, can also be in the form of powder products which can then be consumed as a body health measure or sold.

Abstract

Pisang Tanduk (AAB) merupakan jenis pisang olahan dengan ciri-ciri buah yang tidak cepat busuk, namun menghasilkan jumlah sisir relatif sedikit. Tujuan penelitian untuk menginduksi mutasi pisang Tanduk dan mengidentifikasi klon pisang yang resisten terhadap infeksi Fusarium oxysporum f.sp cubense (Foc). Pisang Tanduk ditanam pada media MS dengan penambahan 6.5 mg L-1 BAP, 1.175 mg L-1 IAA, dan 0.22 mg L-1 TDZ selama tiga bulan. Biakan tunas pisang kemudian di iradiasi gamma pada 0, 20, 30, 40, 50, dan 60 Gy (Co60). Hasil analisis dengan CurveExpert 1.4 diketahui bahwa reduksi pertumbuhan tunas pisang sebesar 20-50% (LD20-50) berada pada kisaran 30.64-68.66 Gy. Hasil multiplikasi tunas setelah 6 bulan menunjukkan bahwa jumlah tunas dan daun terbanyak dihasilkan oleh eksplan yang tidak di iradiasi (0 Gy) dan jumlah nodul meristem dan tunas terendah dihasilkan oleh eksplan hasil iradiasi gamma 60 Gy. Skrining awal ketahanan tunas varian melalui teknik kultur ganda secara in vitro menunjukkan bahwa sebagian besar varian bersifat rentan terhadap cendawan Foc. Tunas varian pisang putatif agak tahan terhadap Foc berasal dari hasil iradiasi gamma 30 Gy. Kata kunci: dosis letal, iradiasi gamma, kultur ganda, pisang olahan.

Abstract

The problem of plastic waste is currently still the main trigger of environmental pollution, its nature that is not easily degraded will produce more waste. One alternative to overcome this problem is to reduce the use of conventional plastics and develop plastics that are more environmentally friendly or also known as bioplastics. In this study, bioplastics made from taro tuber starch with the addition of bagasse cellulose filler were varied based on the type of plasticizer in the form of glycerol, sorbitol, and propylene glycol. The resulting bioplastics were characterized by FTIR analysis, tensile strength test, TGA test, and water absorption test. The process began with cellulose isolation from sugarcane bagasse which obtained a yield of 24.27%, then taro tuber starch extraction with a yield of 27.87%. The results of the FTIR spectrum of bioplastics did not show significant differences in the absorption of wave numbers for each variation of plasticizer types. The functional groups seen from the FTIR results are O-H, C-H, and C-O groups. Bioplastics with the addition of propylene glycol plasticizer have a high tensile strength value of 23.26 Mpa, good thermal resistance with a mass reduction of 75.89%, and an optimum absorption capacity of 29.4%. In future research, it is necessary to vary the concentration of each type of plasticizer and conduct a simple degradation test

Abstract

In vitro medium-term storage using the alginate-encapsulation technique is essential for conserving plant genetic resources, preserving vegetatively propagated species by controlling the growth and development of explants, and maintaining plant biodiversity. The study aimed to obtain the optimum combination medium for the encapsulation of bananas and evaluate the viability of the alginate-encapsulated explants after storage. In vitro, medium- term storage of nodule-like meristem of banana cultivar ‘Barangan’ was performed using sodium alginate, paclobutrazol (PBZ), and Murashige and Skoog (MS) salt. This research consists of 3 stages: (1) Initiation and multiplication of in vitro shoots and nodule-like meristems; (2) In vitro medium-term storage of banana by encapsulation technique; (3) Regeneration of nodule-like meristem explants after in vitro storage. This research showed that the banana's number of nodule-like meristem was optimum on media supplemented with thidiazuron (TDZ) 0.22 mgL-1 and indole 3-acetic acid (IAA) 1.75 mgL-1. Encapsulation explant of nodules-like meristems using 3% sodium alginate in full and half-strength MS salt medium supplemented with PBZ 2.5 mgL-1 and incubated in liquid MS medium was able to store nodule-like meristem for six months. The color of the explants remains green, and the capsule is not damaged. Sub-culture of nodule-like meristem after storage in MS salt medium containing TDZ 0.22 mgL-1 and IAA 1.75 mgL-1 showed that nodules-like meristems could regenerate to form new shoots and nodule-like meristem three months after sub-cultured. This research concludes that encapsulated nodule-like meristem was recorded until six months of storage. PBZ was a necessary retardant in minimizing the growth during storage.

Abstract

E-modules can facilitate student understanding of complex biological concepts, including biodiversity, but their effectiveness also depends on individual student abilities. One significant factor influencing this success is the students' intelligence quotient, which affects how they process and comprehend complex information. This research aims to determine the relationship between intelligence quotient with mastery of biodiversity material using e-modules. The method used in this research is a quantitative descriptive method with correlation studies. The sample was taken from as many as 177 students from SMAN in Tangerang City was collected using multistage random sampling technique. To assess these skills, a test instrument in the form of multiple-choice questions is used. The prerequisite test shows that the data is normally distributed, the data is homogeneous, the data is linear, the data is free from symptoms of heteroscedasticity, the data is not multicollinearity, and the data is free from symptoms of autocorrelation. Through testing the hypothesis, the equation Ŷ = 41.268 + 0.580X1 is obtained. The correlation coefficient obtained was 0.881, which means there is a very strong relationship. . Based on this research, it can be concluded that there is a positive relationship between intelligence quotient, reading comprehension ability, and mastery of biodiversity material using e-modules.
