Abstract

Indonesia salah satu negara agraris dengan penghasil produk pertanian untuk keperluan pangan. Komoditas utama yang paling banyak dikembangkan dan ditanam pada sektor pertanian di Indonesia adalah padi. Lahan pertanian yang luas dan produksi padi yang melimpah menjadi unggulan. Lampung sendiri memiliki kabupaten penghasil taman pangan utama padi yang terdapat di kabupaten pringsewu dan sekaligus lumbung padi salah satunya Kelompok Tani Bina Karya. Kebutuhan pangan yang terus meningkat harus diimbangi dengan jumlah produksi padi yang cukup setiap tahunnya. Terlepas dari lahan dan produksi petani memiliki kendala pada masa tanam padi. Kendala yang terjadi mengakibatkan menurunnya hasil panen secara menyuruh atau malah gagal panen dikarenakan hama. Wereng coklat, belalang, burung bagian dari hama yang menyerang padi. Kelompok Tani Bina Karya melakukan pembasmian hama secara manual dengan menggunakan pestisida dan bertahan sementara. Penggunaan pestisida sebagai pembasmian hama secara kimiawi menimbulkan dampak pencemaran lingkungan, misalnya pencemaran air tanah, petani mengalami keracunan ketika melakukan penyemprotan pestisida. Untuk menyelesaikan permasalahan hama padi tim pengusul membuat teknologi tepat guna sebagai salah satu solusi alternatif dalam pengurangan serta kontroling dan monitoring lahan pertanian dari hama pengganggu dan kondisi lahan. Sistem Kontroling dan Monitoring Hama Padi Berbasis Internet of Thing di Kelompok Tani Bina Karya Pringsewu, Lampung.

Abstract

Coffee husk is an agricultural by-product of coffee production, and its utilization is still limited. So, the study focuses on the potential of coffee husk to be turned into activated carbon. An essential step in producing activated carbon is activation, primarily performed using chemical solvents, such as potassium hydroxide (KOH). However, there are still limited studies on the effect of KOH concentration on the activation of charcoal from coffee husk. Therefore, the study aims to determine the impact of potassium hydroxide (KOH) concentrations on the characteristics of activated carbon derived from coffee husk. The KOH concentration ranges used to activate charcoal were 0 M (as control), 1 M, and 2 M, and were conducted using the completely randomized design (CRD) approach. The characteristics of the activated carbon were analyzed according to the SNI 06-3730-1995 standard, including moisture content, ash content, volatile matter content, and bonded carbon content. The results indicated that KOH concentration significantly impacted the characteristics of activated carbon derived from coffee husk.

Abstract

Coffee husk-activated carbon is a promising biomass for use as an adsorbent due to its composition and abundance. This study aimed to analyze the performance of coffee husk-activated carbon in reducing the free fatty acid (FFA) content of used palm cooking oil. The study examined the effects of potassium hydroxide (KOH) concentration, adsorption time, and the mass of activated carbon. The activated carbon was produced through carbonization at a temperature of 300–400, followed by activation using 0 M, 1 M, and 2 M of KOH solutions. The results showed that the reductions in FFA levels at various adsorption times (2, 4, and 6 hours) were 24.219%, 33.828%, and 46.016%, respectively. The longer the adsorption time, the greater the reduction in FFA levels. In mass variations (0.1, 0.3, and 0.5 g) for 100 ml of used palm cooking oil, the reductions in FFA levels for 0 M, 1 M, and 2 M KOH-activated carbon were 40.234%, 47.968%, and 50.781%, respectively. The study found that increasing adsorption time and the mass of coffee husk-activated carbon resulted in lower FFA levels in used palm cooking oil. The highest percentage reduction in FFA levels, 50.781%, was achieved using 2 M KOH-activated carbon with a mass of 0.5 grams using and 6 hours for adsorption time. These findings suggested that coffee husk-activated carbon was a viable and sustainable adsorbent for improving the quality of used palm cooking oil, potentially reducing its environmental impact and enhancing its reuse potential in various applications.

Abstract

Ulu Belu District, as the largest producer of robusta coffee in Lampung Province, faces challenges throughout its coffee supply chain, from cultivation to marketing. This study aims to examine the structure of the coffee supply chain, evaluate its performance using the Supply Chain Operations Reference (SCOR) model combined with the Analytic Network Process (ANP), and recommend strategies for improvement. The identification results reveal that the coffee supply chain in Ulu Belu District involves several key actors, including farmers, commodity aggregators, collectors, business partners, ground coffee processors, domestic roasters, retailers, exporters, and consumers. This supply chain operates through the flow of products, information, and financial resources among these actors. The coffee supply chain performance measurement results in Ulu Belu District indicate a very poor overall performance score of 58.855. Performance at the three supply chain tiers also reflects concerning conditions: farmers scored 59.721, indicating a very poor performance; collectors scored 62.888, reflecting a poor condition; and business partnerships scored the lowest at 53.957, also categorized as very poor. The strategies for improving supply chain performance include providing training and outreach on Good Agricultural Practices (GAP), implementation of GAP and Good Handling Practices (GHP), implementation of the Common Code for the Coffee Community (4C) certification, increasing storage warehouse capacity, implementing Collaborative Planning, Forecasting, and Replenishment (CPFR) in supply chain management in Ulu Belu, determining safety stock, and planning delivery schedules.

Abstract

Milk can be utilized as a raw material in yoghurt production. The fermentation process of yoghurt involves Lactobacillus bulgaricus and Streptococcus thermophilus as lactic acid-producing microorganisms. The fermentation temperature is a crucial factor affecting the quality of yoghurt; therefore, an accurate temperature control system is required, one of which can be achieved through the implementation of the fuzzy control method. The addition of sweet corn extract is also applied to enhance the flavor of the product. This study aims to analyze the effect of implementing a fuzzy Neo-based temperature control system and the variation of sweet corn extract concentration on the physicochemical properties of yoghurt. The fermentation process was carried out at temperatures of 39.97 °C and 44.99 °C with the addition of 30% and 60% sweet corn extract. The results showed that the best treatment was obtained from yoghurt produced with fuzzy-based temperature control at 44.99 °C and 30% sweet corn extract addition (F-30%-44.99 °C), which exhibited a pH value of 4.3, total soluble solids of 11.5°Brix, viscosity of 124 m.Ps, and lactic acid content of 0.7905%.
