Abstract

The demand for paper grows yearly, but it's getting harder to get raw materials made of wood, so we need alternate raw materials. The artistic appearance of art paper is one with many distinct and natural tones. Since cellulose fibers from trees are typically used in the production of art paper, this has an effect on deforestation, which contributes to natural disasters. Papermaking was done as part of this study in May–June 2022 at the Semen Indonesia International University's material analysis lab. The goal of the study is to ascertain the impact of pre-treatment and cooking temperature on the caliber of paper produced from empty fruit bunches and paper trash. The variables used in this study were cooking temperatures of 80oC, 90oC, and 100oC. Parameters observed were appearance, grammage, thickness, moisture content, and water absorption on paper. The results showed that the difference in cooking temperature of empty oil palm fruit bunches affected the quality of the paper produced. The highest grammage was obtained in the cooking treatment with a temperature of 80oC, which was 208.83 g/m², the highest paper thickness was obtained in the first treatment (A) at 80oC cooking at 0.16 mm, the highest water content was obtained in the cooking treatment with temperature of 80oC is 4.27%, and the lowest water absorption is obtained in the cooking treatment with a temperature of 80oC which is 314.03%, but the fiber characteristics are still stiff.

Abstract

 Abstract Blue swimming crab (Portunus pelagicus) is one of Indonesia's highest-export fishery commodities. Capture fisheries are dominated by fishermen with low productivity, efficiency, and income levels. There is a high-profit disparity between upstream and downstream actors, where fishermen get the lowest profit. This study aims to identify the causes of profit disparities between supply chain actors and propose a supply chain model to solve the profit disparity problem. The supply chain actors observed were fishermen, mini plants, processing companies, and exporters of blue swimming crab. Determining variables that affect profit gain based on the business activities of the supply chain actors of blue swimming crab was carried out. The conceptual model was made using the Soft System Methodology (SSM). The analysis result showed that the causes of profit disparity were the vast number of fishermen, lack of product value understanding, minimum capital and access to capital, awareness of fishing gear utilization, and the individual fisherman's work system. The conceptual model of the blue swimming crab supply chain proposed consists of the formation of fishing groups, coordination between fishing groups and Perum Perindo, collaborating with Pokja and fishing groups, and increasing collaboration between all supply chain actors of blue swimming crab.Keywords: blue swimming crab, fishermen, Soft System Methodology, supply chain Abstrak Rajungan (Portunus pelagicus) merupakan salah satu komoditas perikanan ekspor tertinggi di Indonesia. Usaha ikan tangkap didominasi oleh para nelayan dengan tingkat produktivitas, efisiensi, serta pendapatan yang rendah. Disparitas keuntungan yang tinggi terjadi antara pelaku rantai pasok dari hulu dan hilir. Nelayan memperoleh keuntungan paling rendah. Penelitian ini bertujuan mengidentifikasi penyebab disparitas keuntungan antara pelaku rantai pasok dan mengusulkan model rantai pasok sebagai solusi permasalahan disparitas keuntungan. Pelaku rantai pasok yang diamati adalah nelayan, mini plant, perusahaan pengolah rajungan, dan eksportir. Identifikasi variabel yang memengaruhi perolehan keuntungan berdasarkan aktivitas bisnis pelaku rantai pasok rajungan. Model konseptual dibuat menggunakan Soft System Methodology (SSM). Hasil analisis menunjukkan bahwa penyebab disparitas keuntungan adalah jumlah nelayan yang sangat banyak, pemahaman yang kurang terhadap nilai produk, modal dan akses permodalan yang minimum, kesadaran dalam penggunaan alat tangkap yang aman, dan sistem kerja nelayan yang masih dilaksanakan secara individu sehingga nelayan menerima keuntungan yang paling kecil di antara pelaku rantai pasok dari hulu dan hilir. Model konseptual rantai pasok rajungan yang diusulkan adalah pembentukan kelompok nelayan, koordinasi antara kelompok nelayan dan Perum Perindo, kolaborasi antara Pokja dan kelompok nelayan, dan meningkatkan kolaborasi antara seluruh pelaku rantai pasok rajungan.Kata kunci: nelayan, rajungan, rantai pasok, Soft System Methodology

Abstract

Durian (Durio zibethinus murr) was a tropical fruit from Southeast Asia. Based on the content, the durian peel waste has the potential to be used as a raw material in the process of making oxalic acid. The cellulose content found in durian peel is 50-60%, and there was lignin and starch content of 5% for each. Oxalic acid is an organic compound with the formula C2H2O4. This study aimed to determine the effect of nitric acid concentration and oxidation time of durian peel on yield, oxalic acid content, and the quality of the oxalic acid produced. The method used in this study was the oxidation process. The influential variables in the oxidation process with nitric acid were the concentration and heating time. The higher the nitric acid concentration, the greater the % yield of oxalic acid produced. The independent variables used were nitric acid concentration and time. This research used a factorial Completely Randomized Design (CRD) method with two factors, namely nitric acid concentration (HNO3) and reaction time, and nine treatment combinations were obtained. The concentrations used were 3 M, 4 M, and 5 M then the times used were 60, 70, and 80 minutes. The ratio between nitric acid and durian peel was 1:10 with a temperature of 75℃. The optimum yield occurred at a concentration of 4M HNO3 with a heating time of 80 minutes, where the yield obtained was 22.50%. Oxalic acid from a citric acid concentration of 5M and a reaction time of 80 minutes resulted in oxalic acid crystals melting at 98.6˚C. From the results of this analysis, the synthesized oxalic acid has the same characteristics as pure oxalic acid, so it can be concluded that the product produced from this research is oxalic acid and is classified as dihydrate oxalic acid.

Abstract

Like many other cities, the industrial region of Gresik encounters problematic issues inherent in the burgeoning quantities of waste in landfill sites despite frequent policy implementations and other efforts from the local government. This study aims to examine and interlink between the possibility of the waqf concept and the growing number of waste issues in the Gresik industrial region. By harnessing ethnographical principles such as employing direct and consistent observations and reviewing numerous relevant literature surveys and archival documents, the study attempts to propose an executable design and model that will serve as a framework for stakeholders to address the weaknesses of current less favourable waste treatment programs. A comprehensive and rigorous consideration concludes that the viability of waqf can be a workable prospect and nucleus for an alternative solution and a complementary voluntary enhancement of effective regional policies and programs. An actionable and contributable waqf aspiration can start from the reformulation and rejuvenation of a rural waste bank which is designed to manage an effective balance between profitable and eco-friendly objectives. Professionalism and competence are significant factors in successfully enhancing the functionality of such an institution. Apart from the micro perspective, the bigger picture of a nexus of waqf and waste, including the current intermittent commitment from top policy makers transferred into timely execution, futuristic applicable technology, charitable giving and donation, and sensible collaborative cooperation, constitutes the conceivable determinants for the accomplishment of an efficacious program.
