Pack Test is a series of products of Kyoritsu Chemical-Check Laboratory Cooperation, Japan. It is easy-to-use, anybody can use at anywhere, low cost, nontoxic, safe, and professional-use, onetime use ion-selective color metric water quality checker. The aim of this research is to assess, then next, discuss the significance of applications of this tool. In this order, NH4-Pack Test was selected as an example for the discussions; although there are more than 60 parameters can be detected by pack test such as, COD, Cl-, NO3-, phosphate, hardness, pH, heavy metals, etc.. As for field survey, Ion chromatography was used to measure ammonium concentration of river water in Jakarta. Then detection range of the NH4-Pack Test was compared to the data, and Indonesian and Malaysian national water quality standard. River water quality of Jakarta was weekly degraded at upstream area, but it was seriously degraded at downstream area (up to 5-10 NH4-N mg/L). As for ammonium concentration, obviously the detection range and step of Pack Test was sufficient to assess the ammonium concentrations of rive water in Jakarta. Of course Pack Test is very simplified tool, environmental water quality standard of ammonia for class I in Indonesia and Class I and II in Malaysia were difficult to evaluate. However, it was obviously applicable to check treated effluent and Class III to V water quality of Malaysian environmental standard. Consequently, it is suggested to adopt a double standard policy of water quality monitoring, such as combination of "easy-to-use simplified" and "conventional-accurate". Because of low cost, and professional-convenient design, implementation of Pack Test will significant to empower on-site water quality monitoring in developing country, participative environmental awareness public programs, experience base environmental learning in schools, and other grass-rooted environmental activities.Keywords: Environmental awareness and education, Pack test, Simplified method, Southeastern Asian county

In recent years, the rising competitive environment with shorter product life cycles and high customization forces industries to increase their flexibility, speed up their response, and enhance concurrent engineering designs. To integrate these prospects, supply chain collaboration becomes a pertinent strategy for industries to strengthen their competitiveness. The network design problem is used to implement supply chain collaboration. In the buying and selling process, sharing information between buyer and supplier are important to obtain a transaction decision. The optimimum supply chain profit can be identified by mathematical model of network design problem. The Mathematical Model takes into consideration the uncertainity in negotiation of supply chain, transportation problems, and locationallocation of products from supplier to buyer in the planning based on the time value of money. The results show that the model can be used to optimize the supply chain profit. The supplier gets a profit because income were received in the initial contract, while the buyer profit comes from lower pay.

Dalam Kriteria Perencanaan (KP-01) tentang Perencanaan Jaringan Irigasi disebutkan bahwa penentuan kebutuhan air irigasi untuk penyiapan lahan ditentukan dengan persamaan Van de Goor & Zijlstra (VGZ). Perkembangan teknologi usahatani pada pengolahan tanah dengan mekanisasi mempercepat waktu pengolahan tanah serta penggenangan yg hemat air menjadi pertimbangan melakukan evaluasi kebutuhan air. Makalah ini bertujuan mengevaluasi penentuan kebutuhan air irigasi penyiapan lahan dengan model VGZ dan membandingkan dengan model neraca air (water balance analysis (WBA)) dengan menerapkan irigasi berselang. Dalam evaluasi, simulasi dan penelitian lapang dilakukan khususnya untuk melakukan validasi model WBA di lahan Balai Besar Peramalan Organisme Penggangu Tanaman (BBPOPT), Karawang, Jawa Barat. Simulasi dilakukan pada tekstur tanah liat berat dengan dua kondisi perkolasi (P = 1,5 mm dan P = 2,0 mm) dan evaporasi (E = 3,5 mm dan E = 5,5 mm) dengan periode penyiapan lahan 20 dan 30 hari. Hasilnya menunjukkan kebutuhan air irigasi pada model VGZ berkisar antara 303 – 379 mm atau setara 1,46 – 1,92 l/det. Sedangkan model WBA membutuhkan air irigasi yang lebih kecil berkisar antara 142 - 275 mm, dengan debit sebesar 0,74 l/det dan 1,11 l/det. Model WBA dapat menghemat air irigasi sebesar 27 – 42%. Hasil simulasi ini didukung hasil observasi lapang dengan koefisien determinasi model (R2) sebesar 0,97 sampai 0,99. Dari hasil ini, penentuan kebutuhan air irigasi pada penyiapan lahan di KP-01 perlu ditinjau ulang dengan memperhatikan periode lama penyiapan lahan yang lebih singkat dengan penggunaan traktor maupun kebutuhan tinggi genangan setiap proses penyiapan lahan

Sistem drainase di Desa Cihideung Ilir bermasalah karena selalu banjir setiap tahunnya, Permasalahan ini dilontarkan karena banjir yang terjadi di wilayah itu seharusnya tidak terjadi karena berada pada ketinggian ±20 meter diatas sungai Cihideung Ilir. Salah satu penyebabnya adalah karena drainase sekunder yang ada memiliki fungsi ganda sebagai saluran drainase yang menerima air larian/runoff dari pemukiman sekitar dan berfungsi juga sebagai saluran irigasi pertanian. Dari hasil survei dilapangan banyak ditemukan tahanan-tahanan aliran atau bendung alami yang terbuat dari cerucuk bambu yang memang difungsikan untuk mengalirkan air ke area pertanian. Penelitian ini menggunakan metode Log Pearson III mengacu pada SNI 2415:2016. Berdasarkan temuan analisis didapat nilai debit (Q) rancangan untuk periode ulang 10 tahun yaitu Q = 8,56 m³/detik, sehingga saluran drainase sekunder sudah tidak mampu lagi menampung debit curah hujan. Oleh karena itu, untuk mengatasi masalah banjir ini diperlukan perbaikan, pengembalian fungsi, dan perluasan penampang drainase agar tidak terjadi banjir lagi pada musim hujan. Oleh karena itu, untuk mengatasi masalah banjir ini direncanakan dimensi saluran dengan lebar saluran (B) = 1,50 m, tinggi saluran (H) =1,20 m, dengan kapasitas tampung saluran rencana(Qrencana) = 9,78 m3/detik.

The impact that occurs from the rampant development of residential areas will certainly make the volume of surface water flow or run off become large. Drainage is a system created to deal with the problem of excess water flow that is above the surface of the earth, some of the things that cause excess water are caused by high water intensity and the long duration of rain. In this study, the problem that occurred was in the drainage network in the residential area of Vila Rizki Ilhami 2 Sawangan, which was a transfer of land functions from infiltration land into a residential area. Evaluation that must be done is covering hydrological analysis and hydraulics analysis to get the amount of flood discharge plan that will be used to analyze the capacity of the planned channel so that no flooding occurs at the location of the settlement area when the settlement is built, recommendations for drainage system design and determine the size of the river dimension / size / times that should be made when accommodating water discharge during maximum rain so that the flood control system can be well integrated. With 3 methods of calculating rainfall, the method of calculation is selected using the gumbel method which is SNI (Indonesian National Standard) with a return period of 2 years, 5 years and 10 years. From the evaluation obtained is to add height height or free board to accommodate flood discharge plan.

Indonesia is known as an agricultural country because most of its people cultivate rice in rice fields. BPS through the area survey framework (KSA) stated that the total harvest area in 2022 was 10.45 million hectares. This large area is very likely to cause inefficient water use in rice cultivation considering that most of the cultivation is carried out by inundation. Measurement of irrigation water needs in rice fields has been carried out mostly in the analysis stage, no detailed measurements have been found in evaluating irrigation water needs in rice fields. Evaluating the need for irrigation water in rice fields can easily be done with a water balance approach that considers all aspects of both incoming and outgoing water. This study aims to examine the components of irrigation water needs in the land preparation period. The study was conducted on rice plots equipped with several measuring instruments. Measuring water discharge in and out using CTF, weather data using AWS, and percolation measurements in the field. Measurement of water demand in rice fields on the plot resulted in a total inflow value of 195.38 mm and rainfall of 40.40mm. The total value of evapotranspiration occurred was 104.11 mm, the percolation value was 54.00 mm and the discharge out value was 29.59 mm, so the water loss was 48.08 mm (24.61%)
