Utilization of Different Concentration Sugarcane Molasses to the Quality of Goat Feces-Chicken Excreta-Coconut Husk Organic Liquid Fertilizer

Indonesia is an agricultural country that certainly has the potential for agricultural waste and by-products. Some of those in Indonesia are livestock manure, coconut husk, and sugarcane molasses. Utilization of this waste is limited, which is causing various environmental problems such as environmental pollution. The study is aimed to determine the quality of organic liquid fertilizer made by raw material from goat feces-chicken excreta-coconut husk with various sugarcane molasses concentrations (P0= 0%; P1= 5%; P3= 15%; P4= 20%; P5= 25%). The fermentation was carried out anaerobically for 21 days. The parameters of temperature, pH, organoleptic (color and odor), levels of C-organic, nitrogen (N) total, phosphorus (P) total, potassium (K) total, and biological tests were observed. Biological tests were conducted in the growth of mung bean (Vigna radiata) and spinach (Amaranthus tricolor). Data were analyzed using one-way ANOVA. Variations in the addition of molasses sugarcane did not affect the liquid fertilizer's temperature and pH during fermentation. However, the treatments had positive effect on organoleptic test, C-organic, N total, P total, K total, and biological tests. The addition of 15% sugarcane molasses (P3) showed a dominating performance toward most of the parameters tested. The P3 treatment produced liquid fertilizer with a pleasant smell, and the contents of C-organic, total N, total P, and total K were 2.12%, 0.25%, 0.13%, and 0.13%,  respectively. and produce spinach as a biological test with plant height, number of leaves, leaf width, stem diameter, and root length were 21.82 cm, 6.66 sheets, 3.59 cm, 4.09 mm, and 14.67 cm, respectively

The Effect of Young Coconut Husk on the Quality of Goat Manure-Chicken Excreta Bioculture

The negative impact of chemical fertilizers use is soil fertility declining. The situation occurs because of biological, physical, and chemical properties of the soil is decreased. Agricultural waste is a large commodity which utilization can still be optimized, for example by using as raw material for organic liquid fertilizer. Agricultural wastes that have good quality as fertilizer include goat manure, chicken excreta, and coconut husk. The utilization of agricultural waste as organic fertilizer is one way of creating sustainable agriculture. This study aims to test the quality of liquid fertilizer (bioculture) of goat manure and chicken excreta by adding various levels of coconut husk. Bioculture is made by anaerobic fermentation for 21 days. The parameters observed included levels of C-organic, N, P, and K bioculture, as well as germination tests to determine the presence of phytotoxins. The data were analyzed using one way ANOVA. The treatment of P5 (5% coconut husk) showed the highest levels of N and P, while the K content was not significantly different from the treatment of P4 (2.5% coconut husk). The germination test showed no phytotoxin activity in bioculture

AbstrakPoliteknik Negeri Banyuwangi (Poliwangi) berpartisipasi aktif dalam program swasembada pangan dengan memperkuat sektor pertanian melalui kegiatan pelatihan pada kelompok tani. Kelompok Tani Bangsring Sejahtera merupakan salah satu kelompok tani di desa binaan Poliwangi yang terletak di Kecamatan Bangsring. Kelangkaan pupuk dan tidak dimanfaatkannya limbah peternakan merupakan permasalahan yang coba diatasi, sehingga diciptakan solusi berupa pembuatan pupuk organik dengan bahan baku limbah peternakan. Untuk menunjang kegiatan tersebut di rancanglah suatu alat yang tepat guna (mesin giling serbaguna) yang dapat berfungsi sebagai hammer mill dan chopper. Dengan melimpahnya bahan baku pupuk organik, diharapkan kemampuan petani dalam memproduksi pupuk organik secara mandiri akan mengurangi ketergantungan terhadap pupuk kimia. Diharapkan juga terjadi peningkatan hasil panen dan dapat mendukung swasembada pangan khususnya di Kabupaten Banyuwangi. Kata kunci: pupuk organic; limbah ternak; swasembada pangan; kecamatan bangsring. AbstractPoliteknik Negeri Banyuwangi (Poliwangi) actively participates in the food self-sufficiency program by strengthening the agricultural sector through training activities in farmer groups. The Bangsring Sejahtera Farmer Group is one of the farmer groups in the village supported by Poliwangi, which is located in Bangsring Village. Scarcity of fertilizer and unutilization of livestock waste are problems that this community service activity is trying to overcome, so a solution has been created in the form of making organic fertilizer using livestock waste as raw material. To support these activities, an appropriate tool was designed in the form of a multi-purpose milling machine which can function as a hammer mill or chopper. Due to the abundance of organic fertilizer raw materials, it is hoped that the ability of farmers to produce organic fertilizer independently will reduce dependence on chemical fertilizers. It is also hoped that there will be an increase in harvest yields and this will lead to an increase in farmers' welfare and can support food self-sufficiency, especially in Banyuwangi Regency. Keywords: organic fertilizer; livestock waste; food self-sufficiency; farmer group; bangsring distric

SRY Gene Marker Differences in Native and Crossbreed Cattle

This study focused on the promoter region of the SRY gene with 1,281 bp DNA fragments, including 5'UTR, CAAT signal, and TATA box. Genomic samples of 19 cattle were obtained from Wagyu-BX (n = 2), BX (n = 5), Simmental (n = 2), Limousin (n = 2), Ongole (n = 2), Madura (n = 2), Bali (n = 2), Nellore (n = 1), and Hereford (n = 1). Two flanking primers (forward and reverse) were used for polymerase chain reaction (PCR). The PCR products were then sequenced by using a two-way primer. The obtained sequences were aligned with clustalW software to determine the differences in the nucleotide base arrangement which compiled the promoter region of the SRY gene. The cattle crossbreeding was done as an effort to improve the genetic variations and qualities. The SRY gene is a marker gene inherited from the male side (bull), so the SRY gene is expected to be used as a marker to monitor the crossbreeding. The monitoring of the crossbreed cattle is an initial effort to increase the genetic variations and enhance the genetic qualities without threatening the germplasm purity. The results of this study showed that the overall sample is monomorphic, except for Bali and Nellore cattle. Further research is needed by expanding the analysis area of the SRY gene and increasing the number of samples

A Maluku Sea intermediate western boundary current connecting Pacific Ocean circulation to the Indonesian Throughflow. Nature Communications, 13(1), (2022): 2093, https://doi.org/10.1038/s41467-022-29617-6.The Indonesian Throughflow plays an important role in the global ocean circulation and climate. Existing studies of the Indonesian Throughflow have focused on the Makassar Strait and the exit straits, where the upper thermocline currents carry North Pacific waters to the Indian Ocean. Here we show, using mooring observations, that a previous unknown intermediate western boundary current (with the core at ~1000 m depth) exists in the Maluku Sea, which transports intermediate waters (primarily the Antarctic Intermediate Water) from the Pacific into the Seram-Banda Seas through the Lifamatola Passage above the bottom overflow. Our results suggest the importance of the western boundary current in global ocean intermediate circulation and overturn. We anticipate that our study is the beginning of more extensive investigations of the intermediate circulation of the Indo-Pacific ocean in global overturn, which shall improve our understanding of ocean heat and CO2 storages significantly.This study is supported by NSFC (D.Y., Z.W., Y.L., Y.Y., S.T., J.W., and X.L.: 41720104008; D.Y., J.W., Y.L., X.L., Y.Y., S.T., X.H., and X.Y.: 91858204), the National Key Research and Development Program of China (D.Y. and X.L.: 2020YFA0608800), CAS (D.Y., Z.W., J.W., and Y.L.: XDB42000000), projects.

Phylogenic Tree Analysis of Angus Grade Cattle

Studies about Indonesian cattle genetic purity should be encourage to determine the value of blood relationship and ancestors prediction, so the effort to improve livestock quality could be done correctly. This can be done by studies based on Cytochrome b gene that is only inherited maternally. The samples are 15 Angus Grade cattles from Sragen, Central Java, which have been reared since 1980s. The comparative datas were 54 Cytochrome b gene reference sequences from various breeds and countries (GenBank). The phylogenetic tree arranged by Mega 6 software with maximum likelihood method (Bootstrap values 1000, Tamura-Nei parameter) used 8 out-group Cytochrome b genes sequence comparators (GenBank). The results obtained that the Angus grade cattle had 2 branches ancestors, that branch belongs to Banteng (Bos javanicus) and branch belong to Domestic Cattle (Bos indicus; Bos taurus), with majority of the sample (n=13) were at the Banteng branch. The result indicates that most of Indonesian cattle presently, both crosses and local, had Banteng maternal ancestor and a small portion had close ancestor with Bos indicus or Bos taurus. Strong presumption that ancestors of native cattle in Indonesia and the surrounding regions are species of Bos javanicus, Bos sauveli, Bos grunniens and Bos frontalis
