Abstract

Belimbing Darah (Baccaurea angulata) atau umin merupakan salah satu jenis endemik yang ada di Kalimantan. Manfaat dari belimbing darah yaitu selain buah sebagai edible , bagian lain dari tumbuhan ini juga dapat digunakan sebagai obat. Penelitian ini bertujuan untuk mengetahui Habitat dan Pola Persebaran Belimbing Darah (Baccaurea angulata) pada kawasan Berhutan di Desa Pelimping Kecamatan Kelam Permai Kabupaten Sintang. Hasil penelitian ini diharapkan dapat memberikan informasi dan wawasan tentang habitat dan pola persebaran Belimbing Darah yang terdapat pada kawasan Berhutan di Desa Pelimping Kecamatan Kelam Permai Kabupaten Sintang khususnya, serta menjadi database dalam upaya memanfaatkan dan melestarikan Belimbing Darah umumnya. Penelitian ini dilaksanakan dengan menggunakan metode Jalur. Penentuan jalur dilakukan dengan sytematis sampling with random start. Adapun jumlah jalur dibuat sebanyak 4 buah, berjarak 200 m pada tiap jalur dengan panjang jalur disesuaikan dengan kondisi dilapangan. Pengamatan analisa vegetasi digunakan petak pengamatan ukuran 20 m x 20 m secara kontinyu. Hasil penelitian diketahui 24 jenis tumbuhan yang tumbuh di sekitar Belimbing Darah yaitu Omak/Tampoi, Mentawak, Jambu Monyet/ Jambu Tengkalak, Kemayau, Manggis Hutan, Asam Kandis, Kelampai, Keranji, Petai, Kepuak/Benda, Tapang/Menggiris, Pelaik/Pulai, Gaharu/Engkaras, Mawang, Langsat/Duku, Bungkang/Buah Ubah, Asam Pelam, Kemantan/Bacang, Lilinang, Durian, Kapur, Cempedak, Kedondong Hutan, Meranti, dan Nyatoh. Jenis tanah pada lokasi penelitian tergolong tanah Debu/Lempung berpasir. Rerata curah hujan bulanan pada saat penelitian adalah 226,60 mm, suhu udara bulanan 27 °C, rerata Kelembaban Relatif bulanan 89 %. Pola persebaran Belimbing Darah dari perhitungan Indeks Morisia dari seluruh jalur pengamatan didapatkan hasil indeks yang < 1 , dari hasil tersebut maka diketahui bahwa pola persebaran Belimbing Darah adalah acak. Belimbing Darah yang tumbuh secara acak menunjukkan adanya interaksi yang saling menguntungkan diantara individu-individu yang ada, namun demikian tumbuhan dengan pola pertumbuhan acak justru dapat meningkatkan kompetisi dalam hal unsur hara, cahaya matahari, dan air. Sehingga faktor lingkungan tempat tumbuh menjadi hal yang penting dalam pola penyebaran yang secara acak ini. Hal ini menjadi informasi bagi masyarakat setempat guna menjaga kawasan berhutan di Desa Pelimping ini untuk tetap lestari dan menjadi habitat yang sesuai untuk pertumbuhan dan perkembangan Belimbing Darah di wilayahnya.

Abstract

Permen keras adalah konfeksioneri populer dari sukrosa, sirup glukosa dan air, dan seringkali ditambahkan zat aditif (perasa, pewarna, dan asam). Produk konfeksioneri diasosiasikan dengan nilai kesenangan bagi konsumen. Meski diasosiasikan erat dengan perbaikan suasana hati dan kebahagiaan, konsumen mulai menuntut produk lebih sehat. Gula aren dan madu trigona dapat mengurangi penggunaan gula tebu sebagai bahan baku permen keras. Terdapat 5 formulasi permen keras kombinasi gula aren, gula tebu, dan glukosa (dalam gram) (58:173:19(G1), 56:169:25(G2), 55:164:31(G3), 53:159:38(G4), 50:150:50(G5)) serta air 83 g dan madu trigona 15 g. Rasio gula aren dan gula tebu 1:3 dengan glukosa ditambahkan hingga mencapai berat total. Produk akhir dianalisis untuk karakteristik fisikokimiawi (kadar air, pH, gula pereduksi, dan kekerasan) dan organoleptik (uji parameter hedonik dan uji mutu hedonik dengan atribut rasa, warna, tekstur, dan kelengketan; melibatkan 72 orang panelis tidak terlatih). Kelima formulasi permen memiliki rentang kadar air 0,19%-0,24% dan kadar gula pereduksi 10,51%-11,63%, sesuai dengan SNI 3547:2008 yang mengharuskan kadar air < 3,5% dan maksimum gula pereduksi 24 %. Nilai pH berkisar antara 5,76-6,14 dan kekerasan 181,90-209,55. Uji organoleptik menunjukkan bahwa permen G1, permen dengan kadar gula aren tertinggi dibanding formulasi lain menjadi permen yang paling disukai konsumen. Permen G1 memiliki kadar air 0,19, pH 6,07, gula pereduksi 11,23 dan kekerasan 209,55, dengan rasa agak manis, warna coklat, tekstur keras, dan agak lengket.

Abstract

Karang Sidemen Village is located in Nort Batukliang Subdistrict, Central Lombok Regency, West Nusa Tenggara, Indonesia. This village has promising potential for coffee bean production, which can significantly improve the welfare of the local community if managed properly. This potential includes various coffee varieties that can thrive in the nutrient-rich volcanic soil, offering unique flavors that can compete in both national and international coffee markets. However, this potential has not been fully optimized due to a lack of knowledge and education among farmers and the local community. Best practices in post-harvest handling of coffee beans, such as proper picking, correct processing, and optimal storage, are still not fully understood and implemented. Many farmers still use traditional methods that are less efficient, which can lead to a decrease in coffee bean quality and, ultimately, lower selling prices. To address these challenges, initiatives are needed to organize inclusive socialization and training activities that engage the entire community. Through socialization sessions, farmers and the local community will gain a deep understanding of the importance of applying proper picking methods and accurate coffee bean processing practices. Practical training sessions will enable farmers to enhance their skills, ensuring that each post-harvest stage is carried out with high efficiency and avoiding unwanted quality loss. By implementing the best practices obtained through these socialization and training efforts, Karang Sidemen Village is expected to overcome existing barriers. Through these efforts, it is hoped that coffee harvests can be optimized and the quality of local coffee products significantly improved. This will not only provide direct benefits to farmers but also increase the competitiveness of coffee products from this village in both local and international markets. With comprehensive education, it is expected that the local community can become agents of change to achieve higher quality standards, realizing the extraordinary potential of Karang Sidemen Village’s coffee plantations. Furthermore, collaboration with research institutions and universities can open opportunities for innovation in coffee cultivation and processing techniques. Research focusing on superior coffee varieties, environmentally friendly processing techniques, and effective marketing strategies can add value to coffee products from Karang Sidemen Village. Thus, this village will not only be known as a producer of high-quality coffee but also as a center of innovation and education in the coffee industry.

Abstract

The use of social media in brand management and marketing has become increasingly important, but companies face several challenges in maximizing the potential of social media. Key issues include the need to create relevant and engaging content, overcome content fatigue, respond to algorithm changes, and proactively manage brand reputation. This study aims to explore various aspects related to the use of social media in brand management and marketing. Using a qualitative approach and case studies of several brands that actively use social media, this study investigates the role of social media in building brand awareness, effective marketing strategies, and the impact of influencer collaboration. The findings show that social media can increase brand awareness at a lower cost and with a wider reach compared to traditional media. In addition, the use of visual content and analytical tools on social media has been shown to increase the effectiveness of marketing strategies. Collaboration with influencers is also considered to have a significant impact on expanding brand reach and building more personal relationships with audiences. This study provides recommendations for companies to manage content and collaboration with influencers more carefully to improve marketing effectiveness and maintain brand reputation on social media.

Abstract

Used cooking oil has great potential as a raw material for biodiesel due to its abundant availability and low price, but its quality often decreases due to high free fatty acid and impurities content. This study aims to examine the effect of variations in simple filtration compositions on improving the quality of used cooking oil before the conversion process into biodiesel. The filtration process was carried out using a combination of simple media such as activated charcoal, fine sand, and zeolite in certain ratios. The parameters tested included the density value at 15°C (kg/m³), the kinematic viscosity value at 50°C (mm²/s), and the calorific value (kcal/g) of the produced biodiesel. The experimental method involved several variations in filtration compositions followed by a standard transesterification process. The results of the study showed that the optimal filtration composition was able to produce B40 biodiesel at a temperature variation of 50-60 15°C with a density value of 868.5 kg/m³, a kinematic viscosity of 3,570 mm²/s, and a calorific value of 9772.4 kcal/g according to the standard range of SNI 7182:2015. In addition, biodiesel from simply filtered used cooking oil can be used as a generator fuel with an energy efficiency performance of 34.79% in an 8.5 kVA generator test. This finding provides an alternative for simple, inexpensive, and environmentally friendly used cooking oil processing to support the availability of renewable energy.
