4556448929I1J021004Association Between Gestational Age Classification of Premature Infants and the Incidence of Neonatal SepsisBackground: Neonatal sepsis merupakan salah satu penyebab utama morbiditas dan mortalitas bayi baru lahir di seluruh dunia, termasuk Indonesia, terutama pada bayi yang lahir prematur. Prematuritas diketahui meningkatkan risiko terjadinya sepsis karena ketidakmatangan sistem imun dan organ vital. Berdasarkan tingginya angka kejadian sepsis dan kelahiran prematur, penelitian ini dilakukan untuk mengetahui hubungan antara usia gestasi bayi prematur dengan kejadian sepsis neonatorum di RSUD Prof. Dr. Margono Soekarjo Purwokerto.
Method: Penelitian ini menggunakan desain cross-sectional dengan menggunakan data sekunder dari rekam medis bayi prematur yang dirawat di RSUD Prof. Dr. Margono Soekarjo Purwokerto selama tahun 2023. Pengambilan sampel dilakukan dengan teknik total sampling. Analisis data yang digunakan adalah univariat dan bivariat analisis yaitu uji Chi-Square.
Results: Hasil penelitian menunjukkan bahwa sebagian besar bayi prematur tergolong dalam kategori usia gestasi moderate to late preterm (>32–36 minggu) sebanyak 80,4%, dengan angka kejadian sepsis sebesar 16,4%. Proporsi kejadian sepsis paling tinggi terjadi pada kelompok usia gestasi <32 minggu (32,1%), jauh lebih tinggi dibandingkan kelompok usia >32 minggu (12,6%). Uji Chi-Square menunjukkan hubungan yang signifikan antara usia gestasi dan kejadian sepsis neonatorum (p = 0.000).
Conclusion: Penelitian ini menyimpulkan bahwa terdapat hubungan yang signifikan antara usia gestasi bayi prematur dengan kejadian sepsis neonatorum. Semakin rendah usia gestasi saat kelahiran, semakin tinggi risiko bayi mengalami sepsis. Imaturitas sistem imun dan kebutuhan prosedur invasif menjadi faktor penting yang meningkatkan risiko sepsis pada bayi dengan prematuritas tinggi.		Background: Neonatal sepsis is one of the leading causes of newborn morbidity and mortality worldwide, including Indonesia, especially in babies born prematurely. Prematurity is known to increase the risk of sepsis due to immaturity of the immune system and vital organs. Based on the high incidence of sepsis and preterm birth, this study was conducted to determine the relationship between gestational age of preterm infants and the incidence of neonatal sepsis at Prof. Dr. Margono Soekarjo Purwokerto Hospital.
Method: This study used a cross-sectional design using secondary data from the medical records of premature infants treated at Prof. Dr. Margono Soekarjo Purwokerto Hospital during 2023. Sampling was done with total sampling technique. Data analysis used was univariate and bivariate analysis, namely Chi-Square test.
Result: The results showed that most preterm infants were classified as moderate to late preterm (>32-36 weeks) as much as 80.4%, with a sepsis incidence rate of 16.4%. The proportion of sepsis incidence was highest in the <32 week gestational age group (32.1%), much higher than the >32 week age group (12.6%). Chi-Square test showed a significant association between gestational age and incidence of neonatal sepsis (p = 0.000).
Conclusion: This study concluded that there is a significant relationship between gestational age of preterm infants and the incidence of neonatal sepsis. The lower the gestational age at birth, the higher the risk of sepsis. Immune system immaturity and the need for invasive procedures are important factors that increase the risk of sepsis in infants with high prematurity.

(Studi Putusan Nomor 4/Pdt.G.S/2024/Pn.Lmj)		Perjanjian pembiayaan investasi yang ditemui di masyarakat dalam praktiknya
seringkali terjadi wanprestasi sehingga mengakibatkan kerugian bagi pihak yang
tidak terpenuhi prestasinya. Perlindungan hukum diperlukan untuk melindungi hak-
hak para pihak yang ada dalam perjanjian tersebut. Tujuan penulisan pada skripsi
ini adalah untuk menganalisis perlindungan hukum dalam perjanjian sewa
pembiayaan di Indonesia serta menganalisis kedudukan objek sewa pembiayaan
dalam putusan No. 4/Pdt.G.S/2024/PN. Lmj. Putusan tersebut merupakan putusan
sengketa wanprestasi antara PT BRI Multifinance dan CV Kanza Putri Luis, dalam
putusan ini CV Kanza Putri Luis tidak melaksanakan kewajibannya berupa
membayar angsuran kemudian diberi somasi dan tetap tidak melaksanakan
kewajibannya, setelah diberi somasi diketahui bahwa CV Kanza Puri Luis
mengalihtangankan objek perkara kepada pihak ketiga. Metode penulisan yang
digunakan dalam penulisan ini adalah yuridis normatif dengan pendekatan
perundang-undangan, konseptual dan kasus, spesifikasi penelitian preskriptif
dengan data sekunder. Pengumpulan data menggunakan metode kepustakaan
dengan cara reduksi, editing dan klasifikasi, disajikan dengan deskriptif
menggunakan metode analisis normatif kualitatif. Hasil penelitian berdasarkan
Putusan Pengadilan Negeri Lumajang No. 4/Pdt.G.S/2024/PN.Lmj menunjukan
bahwa adanya perlindungan hukum secara preventif dan represif. Perlindungan
hukum preventif akibat wanprestasi diatur dalam Pasal 1267 KUHPerdata,
sementara itu bentuk perlindungan hukum represif dalam putusan ini diberikan
melalui putusan hakim dengan cara menjatuhkan putusan bagi Tergugat untuk
mengembalikan hak Tergugat sebesar Rp 153.886.310,97 ditambah dengan denda
keterlambatan. Pertimbangan hukum hakim dalam memutus kedudukan objek
perkara berupa berupa 1 (satu) unit Heli Forklift CPC30 M1K2C M400 Tahun
2022 (Baru) Serial Number: 020302S7278 kurang tepat karena tidak
mempertimbangkan Pasal 1977 KUHPerdata. Hakim dalam pertimbangan hukum
hakimnya seharusnya mempertimbangkan Pasal 1977 KUHPerdata karena benda
yang menjadi objek perkara dalam putusan ini merupakan jenis benda bergerak
sehingga pihak yang menguasai benda bergerak tidak atas nama dianggap sebagai
pemiliknya.		Investment financing agreements encountered in the community in practice often
occur defaults resulting in losses for the party whose performance is not fulfilled.
Legal protection is needed to protect the rights of the parties in the agreement. The
purpose of writing this thesis is to analyze legal protection in finance lease
agreements in Indonesia and analyze the position of the finance lease object in
decision No. 4/Pdt.G.S/2024/Pn. Lmj. This decision is a ruling on a breach of
contract dispute between PT BRI Multifinance and CV Kanza Putri Luis. In this
decision, CV Kanza Putri Luis failed to fulfill its obligation to pay installments, was
given a warning, and still did not fulfill its obligation. After being warned, it was
discovered that CV Kanza Putri Luis had transferred the object of the case to a third
party. The writing method used in this writing is normative juridical with statutory,
conceptual and case approaches, prescriptive research specifications with
secondary data. Data collection using the literature method by means of reduction,
editing and classification, presented descriptively using qualitative normative
analysis methods. The results of the research based on the Lumajang District Court
Decision No. 4/Pdt.G.S/2024/PN.Lmj indicate the existence of legal protection both
preventively and repressively. Preventive legal protection against default is
regulated in Article 1267 of the Civil Code, while the form of repressive legal
protection in this decision is provided through the judge's ruling by ordering the
Defendant to return the Plaintiff's rights amounting to Rp 153,886,310.97 plus a
late penalty. The judge's legal consideration in deciding the status of the object of
the case, which is 1 (one) unit of Heli Forklift CPC30 M1K2C M400 Year 2022
(New) Serial Number: 020302S7278, is less accurate because it does not take into
account Article 1977 of the Civil Code. The judge should have considered Article
1977 of the Civil Code in their legal reasoning because the object of the case in this
decision is a type of movable property, and the party who possesses the movable
property without a name is considered its owner.
4556648931C1B021088PERAN MEDIASI DIGITAL TRANSFORMATION PADA HUBUNGAN TOTAL QUALITY MANAGEMENT DAN SUPPLY CHAIN MANAGEMENT TERHADAP KINERJA UMKM DI KOTA BANDUNGPenelitian ini mengkaji dampak Manajemen Mutu Terpadu (Total Quality Management/TQM) dan Manajemen Rantai Pasok (Supply Chain Management/SCM) terhadap kinerja UMKM di sektor kedai kopi di Bandung, dengan Transformasi Digital sebagai variabel mediasi. Penelitian ini menanggapi kebutuhan yang semakin meningkat bagi UMKM untuk meningkatkan efisiensi, kualitas layanan, dan daya saing melalui manajemen mutu dan adopsi digital. Dengan menggunakan pendekatan kuantitatif, data dikumpulkan dari 155 pemilik kedai kopi melalui kuesioner dan dianalisis menggunakan metode PLS-SEM. Hasil penelitian menunjukkan bahwa TQM dan SCM berpengaruh positif dan signifikan terhadap kinerja bisnis dan transformasi digital. Transformasi digital juga meningkatkan kinerja serta memediasi hubungan antara TQM, SCM, dan hasil bisnis, yang menegaskan peran strategisnya dalam mendorong daya saing. Namun, penelitian ini terbatas pada wilayah Bandung dan sektor kedai kopi, sehingga penerapannya secara lebih luas mungkin terbatas. Desain penelitian yang bersifat cross-sectional juga membatasi pemahaman terhadap tren jangka panjang. Penelitian selanjutnya disarankan untuk mencakup wilayah dan sektor UMKM lainnya, serta mempertimbangkan faktor moderasi seperti kompetensi digital atau tingkat persaingan pasar. Bagi pemilik kedai kopi, temuan ini menyoroti pentingnya integrasi TQM dan SCM dengan alat digital. Pemerintah daerah perlu mendukung integrasi ini melalui pelatihan, pembangunan infrastruktur, dan fasilitasi rantai pasok guna meningkatkan adaptabilitas UMKM di era digital.This study examines the impact of Total Quality Management (TQM) and Supply Chain Management (SCM) on the performance of MSMEs in Bandung’s coffee shop sector, with Digital Transformation as a mediating variable. The research addresses the growing need for MSMEs to improve efficiency, service quality, and competitiveness through quality management and digital adoption. Using a quantitative approach, data were collected from 155 coffee shop owners via questionnaires and analyzed with PLS-SEM. Results show that TQM and SCM positively and significantly affect business performance and digital transformation. Digital transformation also enhances performance and mediates the relationship between TQM, SCM, and outcomes, underscoring its role as a strategic enabler in driving competitiveness. However, the study is limited to Bandung and the coffee shop sector, which may restrict broader applicability. The cross-sectional design also limits insights into long-term trends. Future research should expand to other regions and MSME sectors and consider moderating factors like digital competence or market competition. For coffee shop owners, the findings highlight the importance of integrating TQM and SCM with digital tools. Local governments should support this integration through training, infrastructure, and supply chain facilitation to boost MSME adaptability in the digital era.

4557148937A1D021011IDENTIFIKASI MARKA FUNGSIONAL DENGAN APLIKASI MULTIPLEX PCR UNTUK SIFAT KEPULENAN DAN AROMATIK BERAS PADA GENOTIPE PADI INDONESIAPadi (Oryza sativa L.) memegang peran fundamental sebagai komoditas pangan utama, khususnya di Indonesia yang merupakan negara agraris dengan konsumsi beras yang tinggi. Seiring dengan perkembangan zaman, konsumen semakin selektif dalam memilih kualitas beras yang dikonsumsi, dimana beras dengan tekstur pulen dan aroma wangi menjadi sangat diminati. Sifat kepulenan pada beras dikendalikan oleh gen Waxy (Wx), sedangkan sifat aromatik dikendalikan oleh gen BADH2. Kedua sifat beras tersebut membutuhkan metode identifikasi yang lebih cepat dibandingkan dengan metode konvensional. Untuk mengatasi hal tersebut, pemuliaan tanaman telah mengembangkan teknologi penanda fungsional (functional marker) dengan teknik multiplex PCR yang memungkinkan untuk mendeteksi beberapa target DNA secara simultan sehingga dapat digunakan untuk seleksi sifat yang efisien dan tepat. Penelitian ini bertujuan untuk mengidentifikasi marka fungsional yang efektif untuk mendeteksi sifat kepulenan (gen Wx) dan sifat aromatik (gen BADH2) pada genotipe padi Indonesia melalui implementasi multiplex PCR sebagai teknik deteksi molekuler yang efisien. Metode yang diterapkan pada penelitian ini, antara lain uji fenotip, uji genotip, dan analisis keterpautan. Hasil menunjukan bahwa marka fungsional Wx-Ex6 dan Badex7-5 dapat membedakan gen yang terkait dengan sifat kepulenan dan aromatik dengan teknik multiplex PCR.Rice (Oryza sativa L.) plays a fundamental role as a major food commodity, especially in Indonesia, an agricultural country with high rice consumption. Along with the development of the times, consumers are becoming increasingly selective in choosing the quality of rice they consume, with rice that has soft texture and fragrant aroma being in great demand. The softness trait of rice is controlled by the Waxy (Wx) gene, while the aromatic trait is controlled by the BADH2 gene. Both of these rice traits require faster identification methods compared to conventional methods. To address this, plant breeding has developed functional marker technology with the multiplex PCR technique, which allows for the simultaneous detection of several DNA targets, enabling efficient and precise traits selection. This study aims to identify effective functional markers to detect softness trait (Wx gene) and aromatic trait (BADH2 gene) in Indonesian genotypes through the implementation of multiplex PCR as an efficient molecular detection technique. The methods used in this study include phenotyping, genotyping, and linkage analysis. The results showed that the functional markerWx-Ex6 and Badex7-5 could differentiate genes related to softness and aromatic traits using multiplex PCR technique.

Nilai pasar pemain sepak bola merupakan nilai estimasi seorang pemain sepak bola profesional ketika ingin dibeli atau dikontrak tim lain. Berdasarkan data dari Transfermarkt, nilai pasar pemain sepak bola profesional di Liga 1 Inggris berada di tingkat maju. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang mempengaruhi nilai pasar dengan metode regresi LASSO. Metode ini digunakan karena data dari variabel-variabel independen terdeteksi multikolinearitas. Regresi LASSO merupakan suatu modifikasi dari regresi linier berganda yang dapat mengatasi masalah multikolinearitas dan dapat menghasilkan penyusutan variabel independen. Data yang digunakan adalah data statistik Liga 1 Inggris 2023/2024. Berdasarkan perhitungan yang telah dilakukan bahwa pada penelitian ini terdapat tiga variabel independen yang mempengaruhi nilai pasar pemain sepak bola yaitu umur, goal, dan assist. Pada penelitian ini regresi LASSO memiliki R^2 sebesar 0,61 yang artinya variabel independen tersebut bersama-sama berpengaruh cukup signifikan terhadap nilai pasar pemain sepak bola profesional di Liga 1 Inggris. Hasil penelitian menunjukkan bahwa regresi LASSO mampu mengatasi multikolinearitas yang terjadi pada variabel 11 pemain utama dengan menyusutkan koefisiennya menjadi nol.The market value of a football player is the estimated value of a professional football player when he wants to be bought or contracted by another team. Based on data from Transfermarkt, the market value of professional football players in the English League 1 is at an advanced level. This study aims to analyze the factors that influence market value using the LASSO regression method. This method is used because data from independent variables is detected as multicollinearity. LASSO regression is a modification of multiple linear regression that can overcome multicollinearity problems and can result in a reduction in independent variables. The data used is statistical data from the English League 1 2023/2024. Based on the calculations that have been carried out, in this study there are three independent variables that affect the market value of football players, namely age, goals, and assists. In this study, LASSO regression has an R^2 of 0.61, which means that these independent variables together have an enough significant effect on the market value of professional football players in the English League 1. The results of the study show that LASSO regression is able to overcome multicollinearity that occurs in the variables of 11 main players by reducing its coefficient to zero.
