Abstract

Limbah serbuk gergaji dan sebetan dari industri penggergajian kayu rakyat secara teknis dapat digunakan sebagai bahan baku untuk produksi arang dan cuka kayu secara terpadu karena kualitas produk masing-masing memenuhi SNI dan Jepang.  Limbah sebetan yang diproduksi pada tungku kubah batu-bata yang dilengkapi dengan unit pendingin air  menghasilkan rendemen arang 33,6% dan cuka kayu 40,6%. Analisis financial limbah sebetan menunjukkan jangka waktu pengembalian investasi dapat diperoleh setelah 32,9 bulan, tingkat bunga maksimum 79% dan besarnya nisbah manfaat terhadap biaya 1,08. Oleh karena itu hasil penelitian produksi sebetan ini layak dikembangkan pada usaha skala kecil. Limbah serbuk gergaji tidak layak dikembangkan karena investasi lebih tinggi dari nilai hasil produksi. Berdasarkan analisis financial arang sebetan dapat digunakan untuk bahan baku arang aktif yang diproduksi pada tungku arang aktif model pedesaan dengan menggunakan kayu bakar sebagai sumber energinya layak dikembangkan secara komersial, dengan jangka waktu pengembalian investasi dapat diperoleh setelah 35,8 bulan, tingkat bunga maksimum sebesar 13% dan besarnya nisbah manfaat terhadap biaya adalah 1,003. Pemanfaatan cuka kayu pada budidaya tanaman padi diperlukan sebanyak 40 liter/ha dapat memberikan keuntungan usaha pada petani sebesar Rp 9.980.500.- per ha sedangkan tanpa cuka kayu Rp 6.761.500.- per hari.

Abstract

Pengelolaan Taman Nasional Gunung Halimun Salak (TNGHS) menghadapi masalah degradasi sumberdaya alam dan lingkungan, rendahnya ekonomi masyarakat dan meningkatnya jumlah penduduk di dalam ka- wasan. Dukungan dan partisipasi masyarakat dalam menjaga kelestarian taman nasional sulit terwujud tanpa diimbangi upaya nyata yang dapat mengakomodir kepentingan ekonomi dan ekologi secara seimbang. Pene- litian ini bertujuan untuk mendapatkan informasi tentang karakteristik sosial ekonomi masyarakat sekitar TNGHS sebagai bahan masukan dalam pengeloaan taman nasional. Penelitian dilakukan pada bulan Oktober 2012 sampai dengan Mei 2013 dengan mewawancarai sebanyak 297 responden dari delapan desa yang dipi- lih secara sengaja (purposive sampling). Data penelitian dianalisis secara kuantitatif dan kualitatif. Hasil penelitian menunjukkan bahwa masyarakat yang bertempat tinggal di dalam dan di sekitar TNGHS secara sosial relatif homogen. Seluruh responden beragama Islam dengan etnis Sunda, 88% tergolong usia pro- duktif, tingkat pendidikan formal tergolong rendah (86,9%), namun memiliki tingkat kesehatan yang baik (85,18%). Sebagian besar responden (87,9%) adalah penduduk asli. Rata-rata tingkat pendapatan responden sebesar Rp 1.155.000,-/bulan dan di bawah Upah Minimum Regional (UMR) baik menurut ketentuan Pro- vinsi Jawa Barat maupun Provinsi Banten. Rata-rata kontribusi pendapatan dari lahan TNGHS terhadap total pendapatan rumah tangga responden sebesar 38,65% termasuk kategori sedang

Abstract

Honey is a sweet thick liquid made by honeybees as their main products. Due to the increasing demand for honey, the risk of counterfeiting is on the rise, mainly when the production is limited. In term of quality standards, the sucrose content is one of the benchmarks in determining the authenticity of honey. This study aims at determining the sucrose contents of the honey from six regencies in Java. Ten honey samples that consisted of two samples of kapok honey, three samples of mango honey, three samples of rubber honey, and two samples of coffee honey were obtained from Apis mellifera beekeepers. The results showed that the averages of sucrose contents in mango honey, rubber honey, coffee honey, and kapok honey were respectively 4.94%, 3.47%, 10.49%, and 1.02%. The sucrose contents of the ten honey samples averagely met the benchmark. Still, two honey samples exceeded the criterion outlined in SNI-2013 (maximum of 5%), i.e., mango honey from Sragen Regency and coffee honey from the Pasuruan Regency. The high sucrose content of coffee honey was allegedly induced by honey counterfeiting through the addition of sugar solutions.

Abstract

The Indonesian beekeeping industry, grappling with diverse bee species, focuses on the sustainability of operations, particularly with the introduction of Apis mellifera during the early stages of the pandemic. This study explores post-pandemic Apis mellifera honey production in Indonesia, analyzing its impact on prices and business sustainability. Surveys and interviews were conducted with beekeepers in Java and Sumatra, primary islands with significant A. mellifera activities, along with data collection from other regions from January 2022 to October/November 2023. Monthly observations centered on honey production and prices for industrial purposes. The study uncovered two beekeeping systems: migratory in Java and stationery in Sumatra. Carpa honey from Accacia crassicarpa plantation emerged as a suitable industrial honey, displaying sustainable production, seasonality, and a large carpa area as bee forages, contributing to colony growth. Conversely, four Java honey types showed lower productivity, indicating a potential absence of honey seasons. Carpa honey prices ranged from IDR 25,200 to IDR 31,000 per kg, influenced by market size, production, competition, productivity, costs, and producer-consumer interactions. Despite a pandemic-induced surge in the honey market, sustaining high productivity and increasing colony numbers are crucial for long-term honey production sustainability.

Abstract

This study aims to evaluate the effects of combining cocoa bean extract and honey in a functional beverage formulation, focusing on physical, chemical, and antioxidant properties. Cocoa beans used were of the Sulawesi 2 clone, sourced from Donggala, Palu, while honey was sourced from Sumbawa, East Nusa Tenggara. The research methods included analysis of total phenolics, flavonoids, catechin, epicatechin, theobromine, and caffeine content using HPLC, and antioxidant activity was assessed using the DPPH method. The functional beverage was formulated by mixing cocoa powder and honey in various doses, pasteurized at 75°C, and stored at 8-10°C. The addition of honey influenced the phenolic content and antioxidant effectiveness in formulations F1 and F2. Formulation F2 (10.17% cocoa powder, 8.47% honey, and 81.36% water) showed a total phenolic content of 9.36 mg GAE/g. Meanwhile, formulation F1 (10.34% cocoa powder, 6.90% honey, and 82.76% water) had a lower total phenolic content of 6.60 mg GAE/g. Although total phenolics and antioxidant activity decreased due to pasteurization and brewing, F2 (DPPH value of 0.30 mg TEAC/g) demonstrated higher antioxidant activity than F1 (DPPH value of 0.14 mg TEAC/g). Statistical analysis revealed significant differences in total phenolic content and pH between F1 and F2 (p 0.05). However, no significant differences were observed in antioxidant activity (p 0.05). Therefore, it is essential to consider processing methods to maintain the antioxidant activity of cocoa products derived from the Sulawesi 2 clone.

Abstract

Nutritional deficiency is still a problem faced by many families in Indonesia. One of the important issues is the level of protein consumption that is still below the minimum required standard. Edible insects could be one alternative of protein sources since their availability in the nature is quite abundant. This paper analyses six edible species of both cultivated and wild insects for its proximate compositions to measure their nutritional value. The cultivated insects consist of cricket (Gryllus sp.), giant mealworm (Zophobas morio F.), yellow mealworm (Tenebrio molitor L.), and silkworm (Bombyx mori L.), and the wild insects consist of javanese grasshopper (Valanga nigricornis Burm.) and paddy locust (Nomadacris succincta L.). Results shows that the nutritional composition of insects varies widely. Each 100g of dry weight contains of 32.59-76.69% of protein, 6.9-29.47% of fat, 0.92-30.76% of carbohydrate, 2.80-5.79% of ash, 407.34- 517.50 kcal of energy, and minerals about 24.82-31.22 mg of calcium (Ca) and 3.15-4.1 mg of iron (Fe). Some species such as grasshoppers, silkworm pupae and crickets have high protein content which potentially can be utilized as an alternate protein sources to fight against malnutrition and to increase nutritious food consumption. Efforts should be made to encourage the consumption of edible insects as an alternative source of protein. It is especially important to those who live in and around the forest, since the forest area is an excellent habitat for various species of insects.
