Abstract

Madu berasal dari nektar bunga (floral) atau bagian lain dari tumbuhan (extra floral) yang dikumpulkan oleh lebah madu. Madu yang memiliki kualitas baik apabila memenuhi standar kualitas madu tertentu. Kualitas madu dapat diketahui diantaranya berdasarkan kadar air, gula pereduksi, dan hidroksimetilfurfural (HMF). Penelitian ini dilakukan dengan tujuan untuk mengetahui kualitas madu lokal di Semarang dan sekitarnya. Saat ini permintaan madu nasional masih sangat tinggi, dan belum dapat diimbangi dengan produksi madu nasional. Kondisi ini dimanfaatkan oleh produsen madu ilegal untuk melakukan pemalsuan madu. Perlu dilakukan uji berstandar secara berkala untuk mencegah pemalsuan madu. Rancangan penelitian yang digunakan RAL (Rancangan Acak Lengkap) dengan metode purposive sampling pada 5 wilayah produksi madu lokal Semarang yaitu Ngareanak, Limbangan, Mijen, Karangjati dan Klero. Variabel penelitian adalah kualitas madu yaitu kadar air, gula pereduksi, dan hidroksimetilfurfural (HMF). Data dianalisis dengan uji ANOVA pada taraf signifikansi 5%, dan dilanjutkan dengan uji DMRT (Duncan’s Multiple Range Test), dan dibandingkan dengan SNI 8664:2018. Berdasarkan hasil uji kualitas madu lokal dari 5 wilayah di Semarang, rata-rata telah memenuhi standar SNI, nilai kadar air berkisar antara 19,0-25,7%, gula gereduksi berkisar antara 77-94%, dan HMF berkisar antara 3,8-10,8 mg/kg. Honey comes from the nectar of flowers (floral) or other parts of plants (extra floral) collected by honeybees. Honey is of good quality if it meets certain honey quality standards. Honey quality can be determined based on moisture content, reducing sugar, and hydroxymethylfurfural (HMF). This study was conducted to determine the quality of local honey in Semarang and surrounding areas. Currently, the national demand for honey is still very high, and has not been matched by national honey production. This condition is utilized by illegal honey producers to counterfeit honey. Periodic standardized tests are needed to prevent honey adulteration. The research design used RAL (Completely Randomized Design) with purposive sampling method in 5 local honey production areas of Semarang, namely Ngareanak, Limbangan, Mijen, Karangjati and Klero. The research variables were honey quality, namely moisture content, reducing sugar, and hydroxymethylfurfural (HMF). Data were analyzed by ANOVA test at 5% significance level, followed by DMRT (Duncan's Multiple Range Test), and compared with SNI 8664:2018. Based on the quality test results of local honey from 5 regions in Semarang, the average has met SNI standards, the value of water content ranges from 19.0-25.7%, reducing sugar ranges from 77-94%, and HMF ranges from 3.8-10.8 mg/kg.

Abstract

ABSTRACT Sanren F1 shallot is a type of TSS variety that is widely cultivated by Indonesian onion farmers. The cultivation of Sanren F1 shallots is faced with the constraints of non-uniform germination and low seed viability, thus affecting seed quality and yield of TSS shallots. Plasma light radiation is one of the fast, economical and pollution-free plant breeding methods to improve seed performance and yield. This study aims to determine the effect of plasma light period on the germination rate of shallots from TSS seeds of Sanren F1 variety. The research design used was a single-factor Completely Randomized Design (RAL). The factor used is the irradiation period with 6 levels, namely: P0 (control), P1 (5 minutes radiation), P2 (10 minutes radiation), P3 (15 minutes radiation), P4 (20 minutes radiation), and P5 (25 minutes radiation). The variables observed were germination power, germination rate, seed vigor and sprout height. The data obtained were analyzed using Analiysis of Variance (ANOVA) at 95% confidence level for the formation of the results significantly influenced or not. If influential then continued with Duncan's Multiple Range Test (DMRT). The results showed that plasma light treatment at the irradiation level of 15 minutes (P3) gave a real effect on the growth parameters, namely germination height and was able to increase the germination and seed vigor to 100%.

Aplikasi BAP dan GA3 setelah pemangkasan pucuk dapat mempengaruhi pertumbuhan vegetatif tanaman yang selanjutnya berdampak terhadap pembungaan dan produksi cabai. Penelitian ini bertujuan untuk mengkaji pengaruh aplikasi hormon BAP dan GA3 dengan berbagai rasio konsentrasi setelah pemangkasan pucuk terhadap pertumbuhan vegetatif dan pembungaan tanaman cabai merah keriting (Capsicum annuum L.). Pemangkasan pucuk dilakukan pada fase vegetatif akhir, diikuti dengan aplikasi BAP dan GA3. Parameter yang diamati meliputi durasi muncul tunas cabang lateral, jumlah dan panjang cabang lateral, luas daun, kandungan klorofil total, alokasi biomassa, dan periode muncul bunga. Hasil penelitian menunjukkan bahwa aplikasi rasio konsentrasi BAP dan GA3 secara signifikan meningkatkan jumlah dan panjang cabang lateral, luas daun, dan mempercepat waktu muncul bunga dibandingkan kontrol. Perlakuan dengan rasio konsentrasi BAP 0 ppm : GA3 100 ppm dan BAP 200 ppm : GA3 100 ppm memberikan hasil terbaik dalam pertumbuhan vegetatif dan mempercepat pembungaan. Penelitian ini memberikan kontribusi dalam pengelolaan hormon tanaman pasca pemangkasan untuk meningkatkan produktivitas cabai. The growth and yield of chili peppers can be enhanced through the method of shoot pruning. The application of BAP and GA3 after shoot pruning can affect the vegetative growth of plants, which subsequently impacts the flowering and production of chili peppers. This study aims to examine the effects of applying BAP and GA3 hormones at various concentration ratios after shoot pruning on the vegetative growth and flowering of curly red chili peppers (Capsicum annuum L.). Shoot pruning was carried out at the late vegetative phase, followed by the application of BAP and GA3. The observed parameters included the duration of lateral bud emergence, the number and length of lateral branches, leaf area, total chlorophyll content, biomass allocation, and the flowering period. The results showed that the application of BAP and GA3 concentration ratios significantly increased the number and length of lateral branches, leaf area, and accelerated the flowering time compared to the control. Treatments with the ratios of BAP 0 ppm : GA3 100 ppm and BAP 200 ppm : GA3 100 ppm yielded the best results in vegetative growth and accelerated flowering. This study contributes to the management of plant hormones post-pruning to enhance chili productivity.

Abstract

Vanda limbata is one of the most popular ornamental orchids. Currently, its growth is slow, making it necessary to improve its cultivation techniques. One of the possible ways to achieve this is to use plant growth regulator (PGR) treatment. Thidiazuron (TDZ) is a cytokinin used to increase the growth of V. limbata. This study aimed to determine the effect of TDZ concentration on the growth rate of V. limbata. The study involved cultivating V. limbata on planting media and spraying it with TDZ at various concentrations. This research uses a CRD (Completely Randomized Design) single-factor, which is TDZ concentration at three concentrations (factor levels) of 0, 25, and 50 ppm. Data were analyzed using analysis of variance and Duncan’s Multiple Range Test at 5% significance level. The study ran for three months and the following response variables were measure: the number of new leaves, increase in length of old leaves, length of new leaves, increase in width of old leaves, width of new leaves, number of roots, and stomatal density. The results showed that TDZ significantly increased leaf length and the number of new leaves of V. limbata, but decreased the density of stomata. Thidiazuron at 50 ppm was the best treatment for increasing the growth of V. limbata.

Abstract

The Asteraceae family has a wide distribution supported by its adaptive capabilities, including seed morphological traits that influence physiological performance. This study aims to determine the morphological characteristics, physiological performance of seeds, and their correlation in members of the Asteraceae family at the foothills of Mount Ungaran. The findings of this study can also be applied and provide opportunities for further research on seed physiology, particularly in Asteraceae species. The observed parameters in this study include morphological traits (growth habit, achene type, achene length, pappus type, and pappus length) and physiological traits (maturation period, imbibition, germination percentage, germination rate, mean germination time, and vigor) in Asteraceae species at the foothills of Mount Ungaran. The study employs analysis of variance (ANOVA) and Principal Component Analysis (PCA) to assess the significant influence of species differences on seed physiological traits and the strong correlation between morphological and physiological characteristics. Species variation significantly affects seed trait diversity, with morphology playing a crucial role in determining physiological performance and supporting adaptive strategies for survival.

Abstract

Kualitas tanaman hias daun ditentukan oleh pertumbuhan dan nilai estetika tajuk.  Hormon sitokinin berpengaruh terhadap pertumbuhan dan produktivitas tajuk. Penelitian ini mengkaji respon pertumbuhan tajuk, morfologis daun dan nilai estetika tanaman hias Epipremnum aureum terhadap berbagai konsentrasi hormon sitokinin sintetis (6-benzylaminopurine /BAP). Aplikasi BAP dengan konsentrasi 0, 5, 25 dan 125 ppm diberikan melalui metode spray pada daun stek E. aureum umur 3 MST. Pemberian BAP dilakukan satu kali dalam seminggu hingga tanaman berumur 6 MST, selanjutnya diberikan dua hari sekali hingga penelitian berakhir pada 9 MST. Respon tanaman diamati pada umur 9 MST meliputi: respon pertumbuhan (jumlah dan luas daun, panjang batang, berat segar daun, berat segar batang), morfologis daun (warna dan indeks warna daun), dan nilai estetika (corak daun). Hasil penelitian menunjukkan aplikasi BAP 5 ppm, 25 ppm dan 125 ppm meningkatkan pertumbuhan tajuk dibanding kontrol. Peningkatan konsentrasi BAP hingga kisaran 80-100 ppm meningkatkan pertumbuhan tajuk, namun konsentrasi di atas 100 ppm menunjukkan kecenderungan penurunan pertumbuhan. Secara morfologis, peningkatan konsentrasi BAP meningkatkan warna hijau dan indeks warna daun serta pembentukan corak daun, terutama pada konsentrasi BAP 125 ppm. Daun menunjukkan warna hijau yang lebih intens dan corak semburat kekuningan yang lebih tinggi dibandingkan perlakuan lainnya.  Konsentrasi BAP yang optimal untuk meningkatkan pertumbuhan tanaman ditemukan pada kisaran 80-100 ppm. Secara keseluruhan, aplikasi BAP meningkatkan pertumbuhan tajuk dan memperbaiki kualitas estetika daun tanaman E. aureum. The growth and aesthetic value of the shoot determine the quality of ornamental foliage plants. Cytokinin hormones influence the growth and productivity of the shoot. This study examines the response of canopy growth, leaf morphology, and the aesthetic value of the ornamental plant Epipremnum aureum to various concentrations of synthetic cytokinin hormone (6-benzylaminopurine/BAP). BAP application at concentrations of 0, 5, 25, and 125 ppm was applied through a spray method to the leaves of 3-month-old E. aureum cuttings. BAP was used once a week until the plants were 6 months old, then twice every two days until the study ended at 9 months. The plant responses were observed at 9 months of age, including growth responses (number and size of leaves, stem length, fresh leaf weight, and fresh stem weight), leaf morphology (color and leaf color index), and aesthetic value (leaf patterns). The results showed that applying BAP at 5 ppm, 25 ppm, and 125 ppm increased canopy growth compared to the control. Increasing the BAP concentration to 80-100 ppm enhanced canopy growth, but concentrations above 100 ppm tended to decrease growth. Morphologically, increasing BAP concentrations improved the green color and leaf color index and the formation of leaf patterns, especially at the 125 ppm concentration. The leaves showed a more intense green color and higher yellowish patterns than the other treatments. The optimal BAP concentration for improving plant growth was 80-100 ppm. Overall, the BAP application enhanced canopy growth and improved the aesthetic quality of E. aureum leaf plants.
