Authors: Remme R N , Parvin S , Kabir R , Mamun A A , Islam M S , Islam M M
Published: December 2024

Local rice cultivars are an important source of biotic and abiotic stress-resistant genes and require special assistance to improve their qualitative and quantitative traits. A rice somaclone RSC2018-1 was isolated from a vulnerable aromatic rice cultivar Benapole. We investigated nutritional, physical, and cooking qualities of this line and compared with its mother genotype. The experiment was laid out in Completely Randomized Design with four replications. Nutritional analysis revealed that somaclone RSC2018-1 had more protein (16.14%), less fat (0.70%) and carbohydrate (75.19%) than those of mother Benapole. Mineral components e.g. Na and Fe were higher (91.23 ppm and 20.02 ppm, respectively) in the RSC2018-1, while K and Zn contents were higher (196.67 ppm and 31.70 ppm, respectively) in mother Benapole. The size of the grain was much shorter in RSC2018-1 than in Benapole. Shape of the grain is round in RSC2018-1 while Benapole has a bold shape grain. Thousand-grain weight, geometric mean dimension, and surface area were comparatively much lesser in the somaclone line. Sphericity, aspect ratio, bulk density and porosity were higher in somaclone than in Benapole. RSC2018-1 showed a shorter cooking time (21.78 minutes), intermediate alkali digestion, intermediate gelatinization temperature, and soft gel consistency (60.78 mm) through cooking qualities analysis. Considering all physicochemical and cooking properties, the somaclone (RSC2018-1) has been found more superior in comparison with mother cultivar Ranisalute.

Published: December 2024

Purple rice is an unidentified rice cultivar that has purple colour leaf. Some farmers of Bangladesh are showing interest to cultivate purple rice due to its ornamental look and high price of seeds. Hence, before occupying the green rice land by the purple rice, more information about purple rice is necessary to guide farmers properly. Less information about purple rice is available in any area of research except nutritional analysis. Purple rice leaf has high antioxidant properties which play role in stress tolerance. The salt-stress tolerance potentiality of purple rice compared to green rice has been reported. Therefore, as a part of unraveling the heavy-metal stress tolerance potentiality of purple rice, here, we aimed to find out the arsenic-stress tolerance potentiality of purple rice. Arsenic is a toxic metalloid that disrupts plant cells. The effects of different arsenate concentrations (e.g. 0 µM, 100 µM, and 500 µM) on purple rice and BRRI dhan28 were observed based on morpho-biochemical parameters. The results of purple rice were compared with those of green rice (BRRI dhan28). Arsenic stress reduced root length and plant height compared to control in both rice but the reductions in purple rice were lesser than those of BRRI dhan28. Proline, a compatible solute, content was higher in purple rice under both arsenic stress and non-stress conditions compared with BRRI dhan28 and the proline content was decreased in BRRI dhan28 in a concentration-dependent manner. The catalase (an antioxidant enzyme) activity was increased in both rice under arsenic stress conditions compared to control and purple rice showed more activity than BRRI dhan28 in response to arsenic stress. Arsenic stress increased the anthocyanin content (a purple-colored leaf pigment) in a concentration-dependent manner in purple rice than that of BRRI dhan28. BRRI dhan28 showed reduction of chlorophyll and carotenoid contents under arsenic stress compared to the both control and purple rice. The ability of less reduction of phenotypes in purple rice might be achieved by the higher activity of catalase and a higher level of anthocyanin content. Though proline is utilized in BRRI dhan28 under arsenic stress it was either just a symptom or influenced the antioxidant homeostasis without decreasing its concentration. Purple rice may have more potential to protect its cell reductions by arsenic stress than BRRI dhan28.

Role of Extension Service for Climate Change Adaptation in Agriculture: A Systematic Review for Developing Countries
Authors: Ferdousi Rezwana , Islam Md Aminul , Mamun ur Rashid Md
Published: December 2024

Climate change poses significant challenges all over the world. Developing countries whose economic sector profoundly depends on agriculture are especially vulnerable to climate change. To face climate change impacts, adaptation is found to be one of the most important options. In the case of adaptation to climate change in the agricultural sector, extension service is a crucial actor. Therefore, this study explores the different roles agricultural extension services play in developing countries in climate change adaptation. This article follows a systematic literature review through the process of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The present study considered only peer Scopus-indexed journals published between 1996 and May 2024. Total (n=113) research articles are found initially based on the nature of the study and keywords. Total (n=68) articles were excluded primarily based on published language, Scopus-indexed research article, repeated article, geographical location, climate change adaptation, and role of extension service as a key focus of the study. Finally, (n=45) papers were taken for analysis. The synthesized result suggests that extension services mainly perform the following roles in climate change adaptation: i) raising awareness of climate change, ii) innovation dissemination, iii) information management, iv) production management, v) implementing policies and programs, vi) capacity development, vii) supply of input, and viii) liaison with existing climate change actors. Additional research should evaluate extension agents' barriers to achieving successful outcomes and their capacity-building needs in developing countries vulnerable to climate change.

Published: December 2024

Zooplankton is crucial dietary sources for omnivorous fishes and an essential component in freshwater food webs. A six-month investigation carried out from February to July 2023, encompassing three separate seasons, to examine the abundance and variety of zooplankton in connection to physico-chemical parameters in three different waterbodies: intensive, semi-intensive and extensive ponds at Chittagong University campus. Two ponds were chosen for each of the waterbodies that were classified. Monthly fluctuations of some physico-chemical parameters were noted. Most of the ponds were found to be alkaline and TDS, EC, and the variations of air and water temperature were also examined. Remarkable correlations observed between zooplankton and several physico-chemical parameters, either directly or indirectly. Zooplankton in Intensive ponds showed positive significant relationship with TDS (r=0.78, P< 0.1), EC (r=0.81, P< 0.05) and pH (r=0.34, P<0.1). Zooplankton demonstrated positive correlation with air temperature (r=0.61, P<0.1), TDS (r=0.38, P< 0.1) and EC (r=0.33, P<0.05) in semi-intensive ponds and all water parameters except TDS (r=-0.05, P<0.1) displayed strong significant link with extensive ponds. A total of 33 zooplankton species belonging to 19 genera with 3 classes were identified. Rotifers were the most prominent and abundant group of zooplankton, making up 76.75% to 86.49% of entire population and the most numerous genus was Brachionus. Copepods (5.88%-15.79%) and Cladocerans (2.35%-7.63%) were relatively abundant in three waterbodies. Semi-intensive and Extensive ponds showed maximum number of Rotifer abundance (35680u/l & 34980u/l) in summer season. Regarding copepod, maximum abundance were 1320u/l and 4560u/l in Intensive and Extensive ponds respectively during rainy season. Clodocera displayed sporadic abundance across several waterbodies and seasons, where’s Semi-intensive ponds showed maximum abundance in winter season (2680u/l). The current study revealed that extensive ponds had higher zooplankton production density than that of the Intensive and Semi-intensive ponds, with rotifers and copepods being most abundant in summer and rainy seasons, respectively.

Fish is recognized as an important functional food due to the presence of health promoting bioactive compounds. This study aimed to evaluate marine fish species with high muscle yield, low market value and year-round availability to be used as raw material in the production of nutraceutical compounds. A survey was conducted at Cox’s Bazar Sadar and Teknaf upazila in Cox’s Bazar district, Bangladesh targeting stakeholders involved in fish marketing and distribution through structured questionnaires. Nearly 100 fish species belonging to Ariidae, Sciaenidae, Leiognathidae, Nemipteridae, Trichiuridae, Carangidae, Scombridae, Clupeidae, Stromateidae, Mullidae, Harpadontidae, Synodontidae, Lutjanidae and Polynemidae landed at the artisanal landing centers. Of these, four croaker species were deemed suitable for muscle-derived fish peptide (FP) production. Accordingly, market-size Belanger’s croaker (Johnius belangerii), blackspotted croaker (Protonibeadia diacanthus), panna croaker (Panna microdon) and pawak croaker (Pennahia pawak) were collected and analyzed for muscle yield and proximate composition. White the muscle yield ranged from 20.7% to 35.2% of total weight with the highest yield observed in P. pawak which had high protein (18.43±0.3%) and low lipid (0.53±0.1%). A test FP power prepared from P. microdon using 0.02% (w/w) commercial papain, yielding a product with 95.00±1.20% protein, 3.20±0.10% lipid, 1.30±0.10% moisture, 1.70±0.20% ash and 409.1±5.2 kcal energy per 100 g edible raw material that is comparable to high quality hydrolysates prepared from other fish and meat sources. The findings highlight the significant potential of marine fisheries resources to contribute to the global nutraceutical markets and create new economic opportunities for further exploration.

Published: December 2024

Kerbau Lokal merupakan salah satu unsur penting dari biodiversity di Kawasan Geopark Bayah Dome, Kabupaten Lebak. Penelitian dilaksanakan dengan tujuan mengidentifikasi penurunan populasi kerbau akibat adanya alih fungsi lahan dan dinamika jumlah peternak yang terjadi di Kecamatan Panggarangan. Metode penelitian menggunakan metode deskriptif eksploratif dengan pengumpulan data primer melalui observasi, wawancara, dan dokumentasi, serta data sekunder dari UPTD Kesehatan Hewan, Dinas Peternakan dan Kesehatan Hewan dan BPS Kabupaten Lebak. Hasil penelitian menunjukkan bahwa populasi kerbau tersebar di seluruh desa yang ada di Kecamatan Panggarangan dengan jumlah betina sebanyak 370 ekor dan jantan 93 ekor. Selama tahun 2013-2022 telah terjadi penurunan populasi sebesar 226 ekor per tahun yang diiringi oleh aktivitas alih fungsi lahan seperti penurunan fungsi lahan sebesar 5% per tahun, peningkatan fungsi lahan pertanian bukan sawah sebesar 41% per tahun, dan peningkatan fungsi lahan non-pertanian sebesar 12% per tahun. Selain itu, terdapat penurunan jumlah peternak sebesar 28% per tahun. Sehingga dapat disimpulkan bahwasanya alih fungsi lahan di Kecamatan Panggarangan tidak berpengaruh pada penurunan populasi kerbau di Kecamatan Panggarangan karena masih memiliki daya dukung lahan yang besar dan aman untuk budidaya ternak. Namun dinamika jumlah peternak yang ada memiliki pengaruh terhadap penurunan populasi kerbau yang ada di Kecamatan Panggarangan karena penurunan populasi kerbau beriringan dengan menurunnya jumlah peternak yang ada di Kecamatan Panggarangan. Sehingga perlu adanya pemanfaatan lahan yang maksimal untuk memulihkan populasi kerbau yang menurun melalui kontribusi dari masyarakat, pemerintah dan berbagai pihak terkait, serta penambahan kelompok ternak untuk meningkatkan pengawasan.

Jembatan merupakan sarana transportasi yang penting bagi kehidupan karena dapat menghubungkan satu daerah dengan daerah lainnya yang dipisah oleh sungai, jurang, laut atau halangan lainnya. Salah satu jembatan rangka baja adalah jembatan Panel Bailey, dimana jembatan diklasifikasikan sebagai jembatan darurat atau sementara.Studi kasus yang digunakan pada penelitian ini adalah jembatan Bailey yang diproduksi oleh PT. Wiratama Globalindo Jaya. Karena jembatan ini telah banyak digunakan di ruas-ruas jalan Provinsi Maluku Utara, khususnya pada ruas jalan Matuting Rangga-rangga. Penelitian ini analisis kapasitas struktur jembatan dilakukan secara eksperimental yaitu dengan uji beban statik (static loading test) skala 1 : 1. Dari hasil pengolahan data hasil pengujian, diperoleh lendutan maksimum di Tengah bentang akibat beban Truck AASHTO HS20-44 (setara beban truck 32 ton) sebesar 46 mm lebih besar dari lendutan ijin (L/800) yaitu 34 mm. Tegangan yang terjadi pada batang kritis (Strain 2) akibat beban truck AASHTO HS20-44, uji beban statik adalah sebesar 159.69 N/mm2 lebih kecil dari tegangan material yang dipersyaratkan sebesar 400 N/mm2 (fy-min). Dengan demikian struktur jembatan dengan beban truck HS20-44 atau setara beban truck 32 ton masih aman, dimana angka aman (safety factor) tersedia adalah sebesar 2.5. Sedangkan bila dilitinjau dari persyaratan lendutan, lendutan jembatan Bailey yang terjadi tidak memenuhi, namun demikian, jembatan Bailey pada dasarnya adalah jembatan semi permanen atau jembatan darurat, sehingga persyaratan lendutan dapat diabaikan asalkan secara kekuatan jembatan masih mampu menahan beban,

Published: December 2024

PT Putra Mekongga Sejahtera is a nickel laterite mining company located in Pomalaa District, Kolaka Regency, Southeast Sulawesi Province. In a mining activity, many factors affect the aspects of production achievement, one of which is the haul road. Haul roads make a major contribution to smooth transportation operations if the road geometry is in accordance with the dimensions of the conveyance used, then the production target of 80,000 tons / month can be achieved. The current field conditions in terms of road geometry are considered unrepresentative for the movement of hauling equipment and can interfere with mining activities. Based on actual haul road geometric measurements between 5.41-16.98 meters while the theoretical road width for straight roads is 8.72 meters. The actual bend road width ranges from 5.50-15.10 meters while the theoretical bend road width is 14.32 meters. The actual road slope ranges from 0.35% to 17.30% while the maximum road slope is 12%. After evaluation, there are 4 straight road segments that need to be increased in width, namely segments AB, BC, CD and DE and 5 segments of bend road width, namely segments AB, BC, CD, DE and EF, as well as grade reduction in segments AB, BC, DE and EF. Hino FM 260 JD dump truck production before road geometry improvement is 3029 tons/day or 78761.75 tons/month. Hino FM 260 JD dump truck production after ideal road geometry improvement is 3143 tons/day or 81724.38 tons/month.

Authors: Tjiroso Bambang , Umar Kifli , Rais Sandi , Rajak Sahdar , - Zulfikram
Published: December 2024

The purpose of this study is to determine the effect of pouring temperature on defect quality in aluminum castings for beverage cans, using the Lost Foam Casting method. The results indicate that pouring temperature significantly influences casting quality. Higher pouring temperatures improve casting quality by increasing fluidity, allowing the molten metal to better fill the mold cavities. Conversely, lower pouring temperatures reduce the aluminum's flowability. Observed defects primarily include cavities or small holes ranging in size from approximately 0.28000 µm to 0.6843 µm, suggesting porosity defects. Larger cavities (0.6843 µm) likely result from gas entrapment or shrinkage during cooling, while smaller cavities may be due to gas trapped on the surface of the castings.

The research location is in Papaloang village, Bacan Island, South Halmahera Regency, North Maluku Province. Metamorphic rocks in the Papaloang-Bacan Complex can be predicted as thermal dynamo metamorphic rocks (regional metamorphic), and are part of the Sibela Continental Suite which is Precambrian in age. The purpose of this study was to determine the characteristics of these rocks using petrographic methods, namely identifying texture, structure, and mineral content. Based on field observations and laboratory test results, metamorphic rocks in Papaloang are dominated by schist, mica schist, chlorite schist, chlorite-epidote schist, some phyllite, quartzite and gneiss with varying mineral compositions including biotite, hornblende/amphibolite, muscovite, tremolite-actinolite. Also filled with sulfide minerals such as pyrite, chalcopyrite, covellite and chalcocite as well as several iron oxide minerals. Foliation is relatively good, characterized by changes and interlocking of several minerals such as hornblende interlocking tremolite-actinolite, quartz interlocking iron oxide and Opak minerals, and changes in muscophite mica to biotite. This process is most likely related to high pressure from endogenous processes.

The joint property dispute in case number 1726/Pdt.G/2020/PA.Bks at the Bekasi Religious Court reflects a departure from Article 97 of the Compilation of Islamic Law (KHI), which mandates equal division of joint property. The court allocated 1/3 of the property to the Plaintiff (ex-husband) and 2/3 to the Defendant (ex-wife). This research examines the legal basis for the judges' considerations and the relevance of the decision to the KHI and Marriage Law. Using qualitative methods with a normative juridical approach, this study analyzes statutory and case law, using the court decision as the primary data source. The findings show that the judges’ allocation was based on evidence proving the Defendant contributed more significantly to the joint assets through her income and efforts, while the Plaintiff acknowledged his lower income. The judges prioritized fairness by allocating 1/3 to the Plaintiff and 2/3 to the Defendant, reflecting their contributions rather than adhering strictly to Article 97 of the KHI. This decision aligns with Satjipto Raharjo's progressive legal theory, emphasizing justice tailored to specific circumstances over rigid legal norms, thereby ensuring a fair resolution of the dispute.

This study examines judicial considerations in granting marriage dispensation requests and investigates the underlying factors at the Bekasi Religious Court during 2019–2023. Employing a qualitative normative legal research method, the study relies on document analysis, utilizing secondary data sources such as regulations, legislation, court decisions, legal theories, and opinions from legal scholars. The research adopts a statutory and case approach, with primary data sourced from marriage dispensation rulings at the Bekasi Religious Court. Additionally, an empirical juridical approach is employed, integrating legal norms and practical considerations to analyze judicial reasoning in these cases. The findings indicate that the primary factors driving marriage dispensation requests are parental concerns and pregnancies out of wedlock. Judges' decisions are grounded in Article 7(2) and Article 8 of Law No. 1 of 1974, as amended by Law No. 16 of 2019 on Marriage, alongside Article 17 of Supreme Court Regulation (PERMA) No. 5 of 2019. These provisions aim to uphold the protection and best interests of children while balancing statutory regulations, unwritten legal values, and societal notions of justice. Additionally, the principle of Qaidah Fiqhiyyah, prioritizing the prevention of harm (mafsadat) over the pursuit of benefits, underpins judicial considerations in these cases

In contemporary times, the practice of purchasing goods through installment plans has become increasingly common, including in the case of Murabahah gold transactions. However, the prevalence of gold installment purchases has sparked debate, as the system resembles practices in conventional pawnshops and banks, leading to perceptions that Islamic and conventional banks operate similarly. This study aims to analyze the implementation and procedures of Murabahah contracts for gold ownership financing at Islamic Bank BJB Cikarang. Using a descriptive qualitative approach, the research simplifies data analysis to enhance comprehensibility. Data collection involved interviews, literature reviews, observation, and documentation, followed by qualitative analysis, descriptive evaluation, and conclusion drawing. The findings reveal three key points: first, the Murabahah contract implementation for gold ownership financing aligns with Islamic principles; second, the financing procedures adhere to Fatwa No. 77/DSN-MUI/V/2010; and third, there are differing scholarly opinions regarding the permissibility of non-cash gold transactions. Despite these differences, the study concludes that the financing procedures at Islamic Bank BJB Cikarang comply with the fatwa's provisions, underscoring their adherence to Islamic financial principles, while recognizing the ongoing debate among scholars on the permissibility of non-cash gold transactions.
