Abstract

Phalaenopsis amabilis (L.) Blume merupakan salah satu jenis anggrek yang banyak dimanfaatkan sebagai tanaman hias dan sebagai spesies induk dalam program pemuliaan. Eksploitasi yang berlebihan serta laju pertumbuhan vegetatif yang lambat menjadikan anggrek ini memerlukan upaya konservasi ex-situ melalui penambahan nutrisi dan zat pengatur tumbuh, salah satunya Thidiazuron (TDZ). Penelitian ini bertujuan untuk mengkaji pengaruh serta menentukan konsentrasi TDZ yang optimal terhadap pertumbuhan P. amabilis. Penelitian dilaksanakan pada November 2023 hingga Januari 2024 di Tembalang, Semarang, menggunakan Rancangan Acak Lengkap (RAL) satu faktor, yaitu konsentrasi TDZ (0, 25, dan 50 ppm). Parameter yang diamati meliputi panjang dan lebar daun lama, jumlah dan waktu munculnya daun baru, warna daun, jumlah dan waktu munculnya akar baru, serta densitas stomata. Data dianalisis menggunakan ANOVA dan dilanjutkan dengan uji Duncan’s Multiple Range Test. Hasil penelitian menunjukkan bahwa pemberian TDZ berpengaruh nyata terhadap peningkatan panjang dan lebar daun lama, jumlah dan waktu munculnya daun baru, serta densitas stomata P. amabilis. Thidiazuron (TDZ) juga memengaruhi perubahan warna daun. Konsentrasi TDZ 25 ppm merupakan perlakuan terbaik dalam meningkatkan pertumbuhan daun P. amabilis.

Abstract

Arabica coffee (Coffea arabica L.) is a high-value commodity, yet its productivity in Indonesia remains low due to suboptimal cultivation techniques. One of the main constraints is the limited availability of quality seedlings, which is influenced by propagation methods. Vegetative propagation through shoot cuttings is widely used, but often constrained by low survival and root formation rates. The application of plastic bottle covers and goat urine has the potential to improve propagation success by creating a favorable microclimate and supplying growth regulators and essential nutrients. This study examined the effects of plastic bottle cover types and goat urine concentrations on the growth of C. arabica shoot cuttings. The experiment was arranged in a 3×3 factorial Completely Randomized Design (CRD), with two factors: plastic bottle cover types (no cover, open-cap cover, and closed cover) and goat urine concentrations (0, 100, and 180 mL/L). Observed parameters included shoot length, shoot number, leaf length, leaf number, root length, root number, and root diameter. Data were analyzed using analysis of variance (ANOVA) followed by Tukey’s Honestly Significant Difference (HSD) test at a 5% significance level. The results showed a significant interaction between cover type and goat urine concentration. Combining a closed cover with 100 mL/L goat urine produced the highest shoot growth, cutting survival rate, and rooting percentage, while optimal root development was obtained with the closed cover and 180 mL/L goat urine. The most effective treatment was the closed cover combined with 100 mL/L goat urine.

Abstract

Potato (Solanum tuberosum L.) production in Indonesia increased by 4.21% in 2022 compared to the previous year, but this production is still low by international standards. This is caused by low quality and quantity of potato seeds which is sourced from tubers. It is necessary to modify the in vitro cultivation of potato seed sources by utilising seeds that are often wasted with the addition of cytokinins, such as Benzyl Amino Purine (BAP). The aim of this study was to determine the effect of BAP on potato axillary shoot explants sourced from seeds. The study was conducted using a Completely Randomized Design with one factor, namely BAP concentrations of 0, 1, 2 and 3 ppm with 3 replications. The results showed that there is an influence of BAP on the parameters of shoot growth percentage, leaf and root emergence time, plant height, number of shoots, roots, and leaves of potato axillary buds planlet. The 2 ppm BAP treatment tends to give the best response in increasing the number of shoots with an average of 4.33 shoots, making it effective for producing potato seedlings from axillary buds in vitro.

Abstract

Postharvest storage is carried out to control the metabolic rate so the quality of fruits can be maintained properly until it reaches the costumers. Cold storage can reduce metabolic reactions, such as respiration and transpiration. However, storing too long in cold temperatures can cause the quality of the fruit to deteriorate. Each type of dragon fruit has different chemical contents that will affect the quality of fruits after storage. This study aims to determine the effect of the type of dragon fruit, cold storage duration, and interaction between the two treatments. Both type of dragon fruit are packed in PP plastic and then stored at 10°C. Observation were made at different storage durations. This study used RAL, with the first being super red and white dragon fruits. The second factor was storage duration of 0, 7, 14, and 21 days. Data were analyzed using ANOVA and continued with DMRT if it had a significant effect. The result of the study showed that the treatment of fruit type had significant effect on antioxidant activity, vitamin C content, and total sugar level. Storage duration treatment had significant effect on antioxidant activity and vitamin C content. Keywords: Antioxidant activity, Cold storage, Dragon fruit, Post-harvest, Vitamin c.

Abstract

Soybean [Glycine max (L.) Merr.] is a food crop rich in vegetable oil and protein, with increasing demand and economic worth. Increasing soybean production can be accomplished by providing nutrients nitrogen and sulfur, hence increasing the percentage of bloom development into pods. Applying ammonium sulfate at the start of planting can fulfill nitrogen and sulfur fertilizer requirements. The purpose of this study was to examine and determine the ideal concentration of ammonium sulfate for optimal flower and pod formation, as well as the percentage of flower development into pods and leaf sulfur content. Ammonium sulfate was applied in an experimental garden by mixing it into the planting material in polybags under controlled settings. This study employed a single-factor fully randomized design with four doses of ammonium sulfate. The treatments were ammonium sulfate [NH4)2SO4] at various concentrations of 0, 100, 200, and 300 kg/ha administered at the start of planting, with five replications. The research factors were the quantity of flowers, pods, percentage of flower development into pods, and sulfur level in the leaves. The sulfur content of the leaves was determined using an atomic absorption spectrophotometer. Data were analyzed using ANOVA at a significance level of 5%, followed by DMRT if the results were significant. The results revealed that ammonium sulfate 300 kg/ha produced the highest number of flowers, pods, percentage of flower development into pods, and sulfur content in leaves. Keywords: ammonium sulfate, nitrogen, productivity, soybean, sulfur
