Abstract

Malang Regency produced 690,136 tons banana in 2016. The banana production is in line with the waste (banana stalks). Banana stalks contain 83.3% cellulose and 2.97% lignin, of which can be used as raw material for paperboard making. However, the banana leaf paper has a low tensile strength of 7.45 N/mm2, so additional fibers to strengthen the paper is necessary, such as coconut coir which has a tensile strength of 46.67 N/mm2. This research aimed to formulate the material for paper making, such as the fiber source (banana fronds and coconut coir), filler (tapioca), and water to produce paperboard with minimal costs. The research was conducted using a linear programming method with LINDO software. The formulation of a sheet of cardboard produced was 34.79 g of dry banana stalks, 19.20 g of coconut coir, 6.00 g of tapioca, 136.08 g of NaOH, 2080 mL of distilled water, and 1000 mL of water with manufacturing cost of IDR 6,931.15. The paper characteristics has gramature of 323.8 g/m2, moisture content of 19.75%, water absorption test of 743.2 g/m2, tensile resistance of 1.4 kN/m, and stiffness of 5.7 mN.m.

Abstract

Micro and Small Enterprises (MSEs) in Batu city, East Java, have developed, but many have not yet applied for halal certification. One of the efforts to encourage the MSEs halal certification submission is the Halal Assurance System (HAS). The problem is that the HAS training program has not been widely available and has not been assessed for success. This study aimed to assess the training program of HAS implementation for MSEs judging by the satisfaction, knowledge, skills, and attitude of the trainees. Assessment using Kirkpatrick method, level 1 assessments use questionnaires related to trainees satisfaction and level 2 relates to the learning process to change knowledge, skills, and attitudes. The respondents were 17 of local food MSEs. Data analysis using Wilcoxon Test for level 2. The results showed that trainees were satisfied with overall training implementation. Pre-test and post-test results of knowledge, skills, and attitudes aspects differed significantly and improved. The HAS implementation training program can improve respondents' knowledge and attitude in aspects of raw materials, products, production processes, production facilities, storage and handling of materials and products, and improved overall skills. HAS implementation training needs to be continuously developed to support the halal guarantee of food products MSEs.

Abstract

Apple production as a typical fruit of Malang Regency has decreased due to land degradation, land conversion, climate change, and old tree age. This can disrupt the apple supply chain sutainability in Malang Regency. This study aimed to produce simulations of several scenarios for the sustainable apple supply chain development and provide policy recommendations for the apple supply chain sustainability in Malang Regency. The model made consisted of 3 sub models, i.e. economic, social, and environmental. The respondents were 53 farmers, 3 collectors, and 20 retailers. The parameters measured were the profit of farmer, collectors, and retailers, employment, and the area of degraded land. Simulations were carried out in 3 scenarios from 2020 to 2030, i.e. the original conditions (scenario 1), controlling land (scenario 2), and increasing productivity and controlling land simultaneously (scenario 3). The best parameter values were obtained from the scenario 3 simulation results, i.e. adding land by 1.15%/year, reducing the conversion rate to 2.93%, and increasing productivity by 5%/year. This scenario showed that in 2030 yields 4,905,656 kg of apples with profits of farmer, collectors, and retailers were Rp 26,374,922,326, Rp 31,597,327,651, and Rp 27,996,576,448, respectively, employment of 22,349 people/hectare, and a degraded land area of 11.7 hectares. The scenario 3 implementation can reduce the decline in apple land area and productivity over the next 10 years. Policies that can be implemented include providing training and incentives for farmers, strengthening policies on apple commodities, restoring soil, and transitioning to organic farming.Keywords: apple, supply chain, sustainability, system dynamics

Abstract

Terasi constitutes an Indonesian traditional fermented product made from shrimp or fish (or a mixture of both) at a high salt concentration with or without incorporating approved additional ingredients. With a distinct flavor and solid texture (paste), terasi is widely consumed as a seasoning ingredient, but it is still produced using a traditional method that lacks quality inspection. Quality properties of terasi, i.e., physical, chemical, and microbiological aspects, are essential since they highly affect consumer acceptance. This article reviews the quality profiles of terasi, covering such aspects as food safety, health, sensory, shelf life, and its use. The safety of biological, chemical, and physical threats can be used to evaluate the quality of terasi from a safety perspective. In addition, the nutritional content, functional qualities, and satiety characteristics of terasi indicate its quality from a health standpoint. Based on taste, texture, aroma, and color, the sensory qualities of terasi are evaluated to determine its quality. From the time the product is developed until consumers utilize it without any modifications, the quality of terasi based on the shelf life aspect is observed. The quality of terasi in terms of usability is determined by items that are user-friendly or, in other words, practical

Abstract

Adanya Industri 4.0 di seluruh belahan dunia telah mengambil alih sebagian besar aktivitas perekonomian, menyebabkan perlunya peningkatan kreativitas, inovatif dan skill pelaku usaha untuk dapat bersaing dan menarik minat pasar. Kebutuhan mengenai karya intelektualitas sejalan dengan perkembangan teknologi, hingga merek sebagai salah satu karya intelektualitas perlu juga diciptakan dengan unik sebagai gambaran identitas dan asal produk. Tingkat kreativitas yang berbeda-beda dari pelaku usaha ini yang terkadang karya intelektualitasnya mengandung unsur pornografi dengan tujuan menarik minat pasar akan tetapi tindakan tersebut memiliki akibat hukum. Tidak sedikit merek yang mengandung unsur pornografi yang seharusnya tidak dapat didaftar pada Direktorat Jenderal Kekayaan Intelektual sebagaimana Undang-Undang Merek dan Indikasi Geografis akan tetapi kenyataannya terdaftar. Oleh karena itu, perlu dianalisis akibat hukum dari penggunaan unsur pornografi terhadap merek terdaftar itu akan seperti apa. Penelitian ini menggunakan metode penelitian yuridis normatif dengan mengumpulkan dan menganalisa data primer dan data sekunder baik itu asas hukum, prinsip hukum, kasus-kasus maupun ketentuan peraturan perundang-undangan yang mengatur merek yang terdaftar dengan menggunakan unsur pornografi.
