Abstract

PT Simatelex Manufactory Batam (SMB) is engaged in Coffee Maker and Pizza Maker. In the manufacture of these products, they are divided into several buildings in the Batamindo Industrial Park area, the products produced are made based on orders from customers. The products produced by the company are mostly marketed abroad (exports). In the production of Coffee Maker which is located on Jl. Beringin Muka Kuning, Lot 003, Batamindo Industrial Park Area, Batam. Finished products are then stored in the warehouse area on the ground floor of the building (Ground) which has an area capacity of 60%, so that all finished goods cannot be stored, in addition to using an area of 60%, another cause of finished goods not being able to be stored is all mismatched placement. finished goods include Finished Goods Fresh from the production line and Finished Goods to Shipping, so that there are no finished goods to shipping sequences that are not in accordance with CO (Create Order) and there is a buildup of products in the finished goods area. Therefore, the authors are interested in conducting research by anticipating these conditions so that it is necessary to optimize the storage of the finished goods. Improvements made in the form of changes to the flow of finished goods moving, re-layout the optimal warehouse stock level using the Systematic Layout Planning method, and making verbal control monitoring in the warehouse using the Class Based Storage method. From these improvements, the results obtained are an increase in area use by 60% to 80%, and also ensure that the area capacity can meet the company's needs.

Abstract

Stunting in children is the result of failure to thrive at the age of toddlers. Malnutrition experienced in the First 1000 Days of Life (HPK) makes children more at risk for obstacles to physical growth and vulnerability of children to disease. The prevalence in Indonesia in the last 10 years shows that stunting is one of the biggest nutritional problems in toddlers. The purpose of the study was to determine the relationship between feeding patterns and the incidence of stunting in children aged 12-59 months at the Ciuyah Village Posyandu, Sajira District, Lebak Regency. This study used observational analytical research with a case control design approach. The population in this study was mothers who had children aged 12-59 months at the Ciuyah Village Posyandu, Sajira District. The respondents in this study were 82 respondents, consisting of 41 case samples (total sampling) and 41 control samples (simple random sampling). The independent variable in this study was feeding patterns. The dependent variable in this study is the incidence of stunting. Data were collected using questionnaires and children were measured in height using a stadiometer and converted into a standardized score (z-score). Data were analyzed using Chi-Square test with significance α=0.05. The results showed a significant relationship between feeding patterns and the incidence of stunting in children aged 12-59 months with a p-value of 0.012 (p = 0.012). There needs to be an improvement in feeding patterns and promotion from nurses and health workers to provide good food for children.

Abstract

Pemupukan yang efisien penting untuk meningkatan produktivitas kelapa sawit. Namun pemupukan yang dilakukan secara manual menghadapi berbagai kendala, antara lain: biaya yang tinggi, ketidaktepatan dosis, dan distribusi pupuk yang tidak merata. Tujuan penelitian ini adalah menganalisis efisiensi pemupukan mekanis menggunakan fertilizer spreader dibandingkan menggunakan pemupukan manual ditinjau dari segi biaya operasional, penggunaan tenaga kerja, dan distribusi pupuk. Metode yang digunakan pada penelitian ini menggunakan pendekatan eksperimen lapangan dengan pendekatan komparatif antara dua metode pemupukan: secara manual menggunakan tenaga kerja (control) dan pemupukan mekanis menggunakan fertilizer spreader (perlakuan). Data disajikan dan dianalisis dalam bentuk grafis perbandingan biaya dan waktu aplikasi. Perkebunan sawit dengan areal datar, mengakibatkan traktor berjalan lebih cepat sehingga bukaan hopper harus lebih besar. Pada areal sawit bergelombang traktor berjalan lebih lambat, diperlukan flow control yang lebih kecil agar pupuk tidak berlebihan. Pemupukan manual membutuhkan 15–20 orang tenaga kerja per siklus, dengan output rata-rata 850 kg/hari atau 2.4 ha/hari. Selain itu, tenaga kerja tambahan dibutuhkan untuk proses pembagian pupuk ke lokasi tanam dengan output 2,500 kg/hari. Pemupukan mekanis hanya memerlukan 3 orang (1 operator traktor dan 2 helper), dengan kemampuan memupuk 25 ha/hari dalam waktu kerja 8 jam. Hasil penelitian menunjukkan bahwa pemupukan mekanis lebih efisien dengan penghematan biaya (selisih) sebesar Rp 57,429/ha/rotasi. Jika pemupukan dilakukan setahun dua kali maka penghematan total adalah Rp 110.966/Ha/tahun dibandingkan dengan pemupukan manual.
