Abstract

Bawang merah untuk benih umumnya diperbanyak dengan menggunakan umbi. Penelitian bertujuan untukmemperbaiki cara perbanyakan umbi untuk benih yang berkualitas. Penelitian dilakukan di Desa Tambakan, Cagak,Subang ± 600 m dpl. Rancangan percobaan menggunakan petak terpisah dengan tiga ulangan. Petak utama ada tiga,yaitu ukuran umbi benih <3 g, 3-5 g, dan >5 g per umbi. Anak petak ada lima buah yaitu zat pengatur tumbuh enzimkarbonil 0,2 ml/l+ppc mikroelemen metalik 1,0 ml/l, enzim karbonil 0,2 ml/l + metalik 1,5 ml/l, triakontanol 0,2 ml/l +metalik 1,0 ml/l, triakontanol 0,2 ml/l + metalik 1,5 ml/l, dan kontrol. Hasil penelitian mengungkapkan bahwa aplikasiukuran umbi benih >5 g per umbi yang diberi zat pengatur tumbuh triakontanol 0,2 ml/l + ppc mikroelemen metalik 1,5ml/l nyata meningkatkan pertumbuhan dan hasil produksi bobot to tal umbi bawang merah untuk benih.Ame lio ra tion of seed production technology ofshal lot by ap pli ca tion of proper size of mother bulb, plant growth regulators, and microelement nutrient.Shal lot for seed generally are propagated by using the mother bulb. The aim of this experiment was to improve seedproduction technology to find out high quality and quantity of shallot mother bulbs. Research was conducted atTambakan, Cagak, Subang ± 600 m asl. A split plot design with three replication was set up in the field. Main plot wassize of mother bulbs, viz. : <3 g, 3-5 g, and >5 g per bulb, respectively. Subplot was plant growth regulators treatmentin combination with microelement nutrient, viz. : plant growth regulaor en zyme carbonyl 0.2 ml/l + microelementmetalic 1.0 ml/l, en zyme car bonyl 0.2 ml/l + metalic 1.5 ml/l, triakontanol 0.2 ml/l + metalic 1.0 ml/l, triakontanol 0.2ml/l + metalic 1.5 ml/l, and check. Research results revealed that application of size of mother bulb >5 g per bulb incombination with pgr triacontanol 0.2 ml/l + metalic 1.5 ml/l significantly increased growth and total production ofshallot bulbs for seed.

Abstract

Penggunaan pemanis buatan yang semula hanya ditujukan pada produk-produk khusus bagi penderita diabetes, saat ini penggunaannya semakin meluas pada berbagai produk pangan. Oleh karena itu perlu adanya penelitian tentang pengaruh pemberian pemanis buatan terhadap kerusakan organ tubuh khususnya organ hati. Tujuan penelitian ini adalah untuk mengetahui gambaran histopatologi hati pada mencit yang diinduksi pemanis buatan. Penelitian ini merupakan penelitian eksperimental laboratoris dengan rancangan post test randomized control group design. Sebanyak 20 ekor mencit  jantan  galur Balb/c dibagi secara acak menjadi empat kelompok, masing-masing kelompok terdiri dari lima ekor. Kelompok 1 sebagai kelompok kontrol diberi akuades sebagai placebo. Kelompok 2,3, dan 4 berturut-turut diberi  pemanis buatan dengan dosis 5 mg/KgBB, 10 mg/KgBB, dan 15 mg/KgBB. Pemanis buatan diberikan secara oral selama 30 hari. Pada hari ke-31 semua mencit dimatikan untuk diambil organ hatinya. Organ hati selanjutnya dibuat preparat mikroanatomi dan diwarnai dengan HE. Perubahan struktur jaringan hati diamati dan dilakukan penskoran dari 0 sampai 4 berdasarkan derajat perubahannya. Data skor perubahan dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa kelompok 1 dan 2 derajat kerusakannya hampir sama yaitu skor 1-2, sedangkan kelompok 4 derajat kerusakannya mencapai skor 2-3. Disimpulkan bahwa semakin tinggi dosis pemanis buatan yang diberikan semakin tinggi derajat kerusakan organ hatinya. The use of artificial sweetener was originally aimed at the specific products for diabetics, but today the use of artificial sweetener is widespread in various food to products. Therefore, it is needed a research on the effects of artificial sweeteners to organs damage especially the liver. The purpose of this study was to determine the histopathological picture of the liver of mice induced by artificial sweeteners. This study was a laboratory experimental design with randomized posttest control group design. Twenty male mice strain Balb/c were randomly divided into four groups, each group consisted of five mice. Group 1 as the control group was given distilled water as placebo. Group 2,3, and 4 was given artificial sweeteners with rising doses. Artificial sweetener was given orally for 30 days. On day 31th all mice’s liver were taken to be examined. Liver then was formed as mikroanatomi smear and stained with HE. Change in the structure of the liver tissue was observed and scored from 0 to 4 based on the degree of change. Score changes data were analyzed descriptively. The results showed that group 1 and 2 has almost same degrees of damage with score of 1-2, while group 4 reached a score of 2-3 of damage degree. It can be concluded that the higher dose of artificial sweeteners given the higher degree of damage to the organs.

Abstract

The increase in workplace accidents among migrant workers in Pinang, Malaysia, is alarming, with reports indicating a significant rise in injuries, particularly in the construction sector. The low implementation of Occupational Health and Safety (K3) standards contributes to this issue, as many workers lack adequate training and face unsafe working conditions, leading to higher risks of accidents. Many migrant workers do not receive sufficient Occupational Health and Safety (K3) training before starting their jobs, leaving them unaware of potential hazards and safety protocols. The construction sector often exposes workers to hazardous environments, including inadequate personal protective equipment (PPE) and non-compliance with safety standards. Through community service efforts by a team of Civil Engineering lecturers from Universitas Mercu Buana, who possess expertise and OHS certification, it is hoped that a safer and healthier working environment will be created for Indonesian migrant workers in Pinang, Malaysia. After the outreach and training sessions, a total of 21 participants (construction workers) shared their opinions about the PKM KLN activity, in which they rated the level of expectation (importance) at 77% and performance (satisfaction) at 81%.
