Authors: Sopian Y , Sivapirunthep P , Chaosap C 
Published: August 2024

Abstract
Hempseed is the edible fruit of the Cannabis sativa L. plant, potentially serving as feed ingredients in broiler production due to its high nutritional value. Therefore, this meta-analysis aimed to determine the effect of hempseed products (seeds, cakes, or oils) on body weight (BW), feed intake (FI), feed conversion ratio (FCR), carcass yield (CY), and fatty acid (FA) composition (ω-3 and ω-6) in broiler chicken. Ten eligible publications were retrieved from Google Scholar and Scopus databases for the meta-analysis. The random-effects model was used for data analysis in OpenMEE software. Results were expressed as standardized mean differences (SMD) at 95% confidence intervals (CI). Results show that dietary hempseed products increased ω-3 FA (SMD = 1.107; P<0.05) and ω-6 FA (SMD = 0.987; P<0.01) but reduced BW (SMD = -0.403; P<0.05) and FI (SMD = -0.470; P<0.05) compared to the controls. On the other hand, CY (SMD = 0.053; P>0.05) and FCR (SMD = 0.046; P>0.05) were not significantly influenced by hempseed product supplementation. Subgroup analysis revealed that hempseed oil reduced BW (SMD = -1.041; P<0.05) and FCR (SMD = -0.797; P<0.05) but enhanced both ω-3 FA (SMD = 2.372; P<0.01) and ω-6 FA composition (SMD = 1.630; P<0.01). There were no adverse effects of hempseed and hempseed cake on BW (P>0.05), but a higher FCR (SMD = 0.658; P<0.05) was obtained on broilers fed with hempseed. Moreover, dietary hempseed and hempseed cake also increased ω-3 FA (SMD = 0.952; P<0.05) and ω-6 FA composition (SMD = 1.107; P<0.01), respectively. This study concluded that dietary hempseed products had beneficial effects on the fatty acid composition of meat. However, its effect on growth performance should be considered.

Abstract
The fermentation process using lactic acid bacteria (LAB) in cheese manufacturing plays important roles to enhance the nutritional content of cheese. This study aims to observe the effect of the addition of Lactobacillus casei in goat’s milk cheese manufacturing. Changes in physicochemical and organoleptic characteristics were observed during cheese ripening. Cheese was made using 8% of L. casei as starter and its changes were observed for 8 weeks of ripening. The results showed that the acidification process in cheese by L. casei resulted in a yield value of 10.85%. The ripening period affects significant changes in physical and chemical indicators, except for pH. Observations during cheese ripening from the 4th to the 8th week indicate that pH tends to stabilize at pH 5, protein increases by approximately 16%, and the decrease in moisture and fat content was by 18% and 15%, respectively. The best quality of cheese was obtained by 8 weeks of ripening. After 8 weeks of ripening, the cheese was yellow in color, has a hard texture with cheesy aroma, sour taste, and contains approximately 1.8 × 106 CFU/ml of LAB. The study of LAB application in goat’s milk cheddar cheese will provide an innovation in cheese production.

Published: August 2024

Abstract
The presence of limited nitrogen plays an important role in the lipid production process in oleaginous fungi, highlighting the significance of achieving an appropriate carbon-to-nitrogen (C/N) ratio to optimize biomass and lipid production. Mucor irregularis JR 1.1, an oleaginous fungi inoculated from Yogyakarta, Indonesia, shows the ability to accumulate lipids up to 43.46% of its total dry biomass. However, the optimum C/N ratio for lipid production of M. irregularis JR 1.1 has not yet been determined. This research aims to explore the effects of different C/N ratios on biomass and lipid production of M. irregularis JR 1.1, utilizing glucose as the primary carbon source. Various C/N ratio ranging from 15 to 75 was examined, alongside with incubation time of 144 hours at 29°C. The optimum C/N ratio was then utilized to construct a growth curve to evaluate the influence of varying incubation time on biomass and lipid production, as well as the lipid productivity of M. irregularis JR 1.1. Results revealed that the highest level of biomass and lipid production were achieved at C/N ratio 40. Additionally, variations in incubation time exhibited a consistent rise in both biomass and lipid production, with the highest lipid productivity achieved at 72 hours of incubation. This study suggests that variation in the C/N ratio and incubation time have discernible impact the biomass and lipid production of M. irregularis JR 1.1 while variations in incubation time did not affect the lipid productivity.

Published: August 2024

Abstract
Increasing national rice productivity can be achieved by optimizing existing resources, including rainfed rice fields in highlands areas. Rainfed rice fields in Indonesia are quite diverse in agroecosystem conditions, ranging from lowlands to highlands. Indonesia has the potential for highlands that can be planted with rice to support national rice production. The high variety of biophysical, edaphic, and biotic conditions of the main agroecological areas of rice cultivation makes it difficult to obtain varieties that can grow well in all types of agroecosystems. The purpose of this study is to determine the potential yield and adaptability of rice hope strains to anaerobic germination conditions in rainfed land and highland rainfed rice strains. Ten rice strains and two reference varieties from The Indonesian Centre for Rice Research Sukamandi in West Java were tested in 2021, with four repetitions. The area of each plot of 4 x 5 m was carried out on rainfed rice fields in Kerinci regency with an altitude of 788.5 meters above sea level and a Sungai Penuh regency of 795 meters above sea level. Observations were made of vegetative, generative parameters of plants, as well as temperature and humidity. Results showed that the strains with the highest production and medium harvest age had good observational agronomic parameters, namely in strains B15617E-4-MR-3, BP29337-2-CRB-0-SKI-0-7-PWK-1-SKI-3-3, and BP19980-JK-2-IND-2-SKI-0-PWK-1-SKI-5-1.

Abstract
Sorghum is potential to develop on marginal lands in Indonesia, including Gunungkidul, Yogyakarta, despite very limited information on sorghum diversity in this area. This study aimed to describe morphological variation and assess the value of genetic diversity based on morphological characteristics of local sorghum cultivars in Gunungkidul compared with new superior varieties. Exploration and sampling were conducted in Wareng Village, Gunungkidul, Yogyakarta. Observations of morphological characters were made based on sorghum descriptors. Similarity of morphological characters was analyzed using Simple Matching (SM) coefficient, and dendrograms were made using Unweighted Pair Group Method with Arithmetic Average (UPGMA) method. Results showed three local sorghum accessions in Gunungkidul with variations in 44 morphological characters. Genotypes S1 (Bioguma) with S4 (Samurai) and S3 (Plonco) with S4 (Samurai) had highest SMC coefficient (0.82), indicating that both genotypes were similar in 82% of their attributes. Whereas, genotypes S6 and V3 had lowest SMC coefficient (0.36), indicating that both genotypes were similar in 36% of their attributes, while dendrogram results showed two major groupings based on vegetative and generative characters observed. This study provides the first complete information on sorghum diversity in Gunungkidul, useful to be basic information for future sorghum development in this area.

Abstract
High Fe and Zn content rice varieties are believed to be effective in reducing the high prevalence of deficiencies. Searching gene donors for high Fe and Zn content is required to further increase the Fe and Zn content of the existing varieties. This preliminary study that was conducted aiming to quantify the Fe and Zn content of rice genotypes of various local (set I) and released (set II) varieties in Indonesia. Set I experiment was conducted in 2014 in 328 Indonesian local variety measured using an ED XRF machine at the ICRR laboratory in Subang. Set II experiment was conducted in 32 rice genotypes using T XRF machine at BRIN laboratory in Bandung in 2022. The results showed the existence of variation of Fe and Zn content among local and improved varieties indicating the potential of breeding efforts to increase Fe/Zn content. Set I with more huge numbers of genotypes showed normal distribution for both Fe and Zn content but not for set II. Fe and Zn content were positively correlated in both sets. Further trial with replications at the same planting environment and uniform method is required to confirm these results.

Abstract
Indonesia has lot of sub-optimal land, especially outside Java, but generally the land is acidic, contains lots of heavy metals and is poor in nutrients, making it less suitable for agriculture, including soybean cultivation. Efforts to improve land conditions through the application of liming are quite helpful, but are inefficient because they are easily washed out by rainwater and require expensive labor and costs for large areas. The use of tolerant and adaptive varieties for acidic land are effective solutions. Biosoy-1 and Biosoy-2 are new superior soybean varieties released by Ministry of Agriculture which have high yield potential (more than 3 tons/ha) and big grain, but are less adaptive to sub-optimal land so that the planting area is still limited. Efforts to improve the Biosoy variety for aluminum stress tolerant have been carried out through the introgression of the MaMt2 gene from transgenic soybean lines into the Biosoy variety. Thirty of F1 soybean seeds have been produced and 24 plants of them were positive for carrying the MaMt2 gene. Furthermore, the F1-MaMt2 plants were backcrossed to Biosoy several times in order to obtain a soybean line with high yield and tolerance to aluminum stress. Currently, a total of 16 number of BC3F1 seeds are being planting in confined screen house for molecular analysis and following by backcrossing to Biosoy-1 variety to produce BC4F1 seeds.

Published: August 2024

Abstract
Acidic soils present a major abiotic challenge for various crops, including maize. Such an environment may cause nutrient unavailability, leading to poor growth and yield. Selection using multiple traits enables breeders to select maize hybrids that appeal to preference. This research aimed to obtain information on the genetic variability and predict the selection response of tropical maize hybrids based on multiple traits. Fifty-two maize hybrids, including six checks, were evaluated under acidic soils using an augmented RCBD with three blocks for the check varieties. The results showed that the genotypes significantly affected several agronomic traits and yield. Moderate to high e heritability was found for most traits. The greatest positive direct effect on yield was demonstrated by ear diameter, stay-green, and shelling percentage. G13, G14, G49, G50, G35, G39, G09, and G51 were selected maize hybrids using the MGIDI method. Selection using multiple traits is expected to have selection precision while considering its strengths and weaknesses. The selected genotypes may be subjected to a multi-environment trial to understand the influence of genotype by environment interaction.

Published: August 2024

AbstractCloves, originating from Indonesia’s Moluccas Islands, have spread across various regions over time. Semarang, Central Java, is a notable clove production center, showcasing distinct advantages. Despite originating in the 1980s, Semarang’s clove production remains robust, boasting longevity and high yields. This study focuses on Semarang’s clove plantation, which belongs to the Samyo Rahayu Farmers Group in Gebugan Village, Bergas. The research aimed to evaluate clove yield and morphological traits. The methodology involved selecting high-yield blocks followed by the selection of mother trees. Morphological characteristics like canopy shape, stem dimensions, leaf attributes, and inflorescence traits were examined. Additionally, GC-MS analysis identified oil chemical components. Findings revealed an average plant height of 11.72 m and trunk circumference of 115.55 cm. Canopy shape primarily exhibited a cylindrical form with 1-3 main branches. Leaves displayed green, glossy, and smooth textures upon maturity, transitioning from reddish to bright red in their young shoots, with petiole length of 2.17cm, leaf length of 10.96 cm, and leaf width of 4.39 cm and ratio 2.5. Inflorescences followed a short type, with pink to red mature flower tubes, rounded or slightly pointed corollas, and distinctive red corollas – characteristics typical of the Zanzibar type. Inflorescences were characterized by short arrangements, with an average of 12-20 flower buds per inflorescence. There were tree-to-tree fresh flower yield fluctuations between 40 to 100 kg. Dried clove bud with water content 5.73-6.82 % contained oil 14.67 – 17.96 %. Essential oil compounds analysis indicated the presence of 15-20 chemical components, with eugenol constituting over 70%, signifying its primary compound. This population may be recommended as genetic material for breeding high-yielding cloves.

Abstract
Garlic is a national priority commodity with regards to reducing imports. One of the obstacles in its national production is the limitation of seed quality. This study aimed to investigate how auxin impacts the regeneration of embryogenic callus in three local garlic varieties. The experiment employed a two-factor Complete Randomized Design, involving varieties (Lumbu Putih, Geol, and Sangga Sembalun) and auxin types: A (IAA 1 ppm), B (IAA 3 ppm), C (IAA 5 ppm), D (IBA 1 ppm), E (IBA 3 ppm), and F (IBA 5 ppm). Each treatment was repeated three times so that the total treatment was 54 experimental units. Embryogenic calli, weighing about 0.2 g, were cultivated on the treatment medium. The observed variables were the diameter and texture of the callus, as well as the number of green spots on the callus. The results showed no significant interaction between variety and auxin treatment, but variety had a significant effect on callus diameter. The largest callus diameter was shown by the Sangga Sembalun variety under treatment C (2.75 mm) with a friable texture, yellowish color, and rooted structure, while the smallest callus diameter was produced by the Geol variety in treatment E (1.20 mm) with a non-friable texture and white color. The highest number of green spots was also produced from Sangga Sembalun in treatment D (7 green spots). It was concluded that auxin plays a role in the regeneration of somatic embryos in garlic, but its effectiveness depends on the genotype.

Revising the Screenplay
Authors: Buchman Andrew 
Published: August 2024

Abstract
“Revising the Screenplay” explores the successive revisions made by co-directors Gene Kelly and Stanley Donen before and during production, accommodating late casting changes and informed by many rehearsals as well as shooting days. Later controversies over authorship of the screenplay receive a nuanced discussion. Archival documents demonstrate that many elements were still in flux while the film was in production, including the film’s opening credit sequence and its ending. In collaboration with screenplay authors Betty Comden and Adolph Green but also working more independently after the writers left Los Angeles to work on a new Broadway show, the directors integrated a series of newly devised musical numbers including inventive, complex montages smoothly into the story. Kelly and Donen’s cinematic, diegetic, and dialogic strategies ended up toning down or eliminating moments of biting satire and amplifying or adding in elements of nostalgia and romance.
Music and Sound
Authors: Buchman Andrew 
Published: August 2024

Abstract
Chapter 4 examines the genesis of the soundtrack, analyzes some of the musical materials, and traces Arthur Freed and Nacio Brown’s careers as successful songwriters from the 1920s. It describes the complex collaborative work of the music department at MGM. Conrad Salinger created most of the arrangements for the numbers featuring Kelly. Repetitive leaps of an octave help make Brown’s music memorable. The octave leaps in the melodies of “Singin’ in the Rain” and “You Are My Lucky Star,” are juxtaposed at the film’s outset, creating a motivic connection between the two songs. Martin’s swing band arrangement of “Moses” and Heglin’s lively arrangements of “Fit as a Fiddle” and “Good Morning” also receive attention. Careful adjustments such as almost imperceptible quick fade-ins, fade-outs, and subtle adjustments in volume in the music, dialogue, and sound effects overseen by Lela Simone are also important expressive components in the film’s soundtrack.

Abstract
The chapter “Reception History” examines the advertising and promotion of Singin’ in the Rain at its premiere, competition from other entertainments, and subsequent reviews. Selections from seven decades of criticism and scholarship document the film’s rise to prominence. Takeoffs and remixes by contemporary artists display a range of responses to the work. Reinterpretations by Stanley Kubrick, Michael Jackson, BTS, and contemporary hip hop performers like Dreya Mac among others suggest that the film is becoming a referential resource for reinventions of the styles and forms of mediated musical dance and drama.

Abstract
This chapter recounts Gaston Crunelle’s postwar performing activity. He left the Pasdeloup Orchestra in 1945 but continued as principal flutist of the Opéra-Comique until 1964. The Quintette instrumental de Paris was active with tours, broadcasts, recordings, and commissions of new works. Since the quintet disbanded in 1965, other ensembles have continued to perform and record the repertoire they created. Aside from his work in this ensemble, Crunelle made many significant recordings of music from the Baroque through Debussy. His combined income enabled him to reside in a luxurious apartment in the sixteenth arrondissement of Paris.
