Abstract

The yard is part of the house that is multifunctional and can provide positive benefits and can even support the needs of the family. One of the productive activities in the yard is to cultivate vegetables. However, most of the yards in coastal villages, such as Laikang Village, have not maximized their function and it is difficult to cultivate vegetables. As a solution, a method is needed to support plant cultivation activities in Laikang Village. This service activity aims to provide cultivation training and the manufacture of hydroponic and verticulture installations for groups of housewives in Laikang Village. This community service activity is carried out using the rapid rural appraisal (RRA) and participatory learning and action (PLA) methods, with the stages of activity in the form of presentation of material related to the theme of the activity, demonstration and direct practice by participants, mentoring, and evaluation. From the series of activities, it can be seen that the people of Laikang Village are very enthusiastic and interested in the technology introduced. This is indicated by the high level of participation and activeness of the participants. In addition, there has been a change in the behavior of the Laikang Village community to take advantage of their previously poorly maintained yard, but has now become a productive yard. This vegetable cultivation activity is also still being continued by the participants independently after the training activities, which indirectly indicates the mastery of knowledge and skills, as well as the achievement of the main goals of service activities.

Abstract

Tujuan penelitian ini yaitu untuk mengetahui jumlah lemak yang dihasilkan setiap lapisan atau tumpukan pada suhu ruang dan suhu 60°C serta mengetahui besar tekanan yang dibutuhkan untuk pengepresan pada tiap lapisan/tumpukan biji kakao. Prosedur kerja yang dilakukan dalam penelitian ini adalah sebagai berikut : (1) Pengupasan Testa Kakao, (2) Pengeringan dan Pengpresan Nib Kakao dengan perlakuan 3 lapis nib kakao, 5 lapis nib kakao, dan 7 lapis nib kakao, (3) Analisa Kadar Lemak/minyak, (4) Analisa Kadar Air. Hasil penelitian menunjukkan jumlah persen lemak/minyak yang dihasilkan berdasarkan efektifitas pengempaannya ialah pada 3 lapis atau tumpukan suhu ruang sebesar 22%. Pengepresan pada suhu 60°C dapat lebih mudah mengeluarkan lemak nib kakao dari yang sebelumnya (suhu ruang) yang sulit untuk dipisahkan. Besar tekanan dipengaruhi oleh tebal lapisan atau tumpukan nib kakao. Pada 3 dan 5 lapis/tumpukan nib kakao diperoleh sampai tekanan 25 ton, sedangkan 7 lapis atau tumpukan sampai 28 ton (terlampir pada hasil penelitian). Kesimpulan yang di peroleh dari penelitian ini (1) Tebal lapisi tumpukan nib kakao berbanding lurus terhadap jumlah (%) minyak kakao yang dihasilkan pada pengepresan suhu ruang dan suhu 60°C. Makin tebal lapisan nib kakao, rendemen lemak diperoleh semakin rendah. (2) Pengepresan nib kakao pada suhu ruang menghasilkan minyak 17% - 22% pada tekanan mininal 8 ton dan maksimal 28 ton. (3) Pengepresan padatan nib kakao suhu 60°C dapat mengeluarkan minyak/lemak 16% - 24%, dari padatan nib kakao hasil pengempaan suhu ruang dengan tekanan minimal 8 ton dan maksimal 28 ton. (4). Rendemen pengepresan dicapai 45%, jumlah tersebut sama/mendekati rendemen industri.

Abstract

          Penelitian ini adalah penelitian eksperimen yang bertujuan mengisolasi bakteri asam laktat (BAL) indigenus yang terlibat dalam fermentasi spontan biji kopi robusta asal Bantaeng pada interval waktu fermentasi 0, 3, 6, 9, 24, 48, dan 72 jam serta untuk mengetahui aktivitas enzim dari isolat bakteri asam laktat indigenus sebagai upaya pengembangan kultur starter dalam fermentasi biji kopi secara terkontrol. Hasil penelitian menunjukkan isolasi berhasil dilakukan pada 37 isolat bakteri yang terlibat dalam fermentasi spontan biji kopi robusta. Hasil identifikasi sederhana yang dilakukan secara bertahap menunjukkan hanya 12 isolat bakteri yang bersifat katalase negatif, Gram positif, non spora, non motil, tidak menghasilkan gas (homofermentatif), tumbuh pada suhu 10 °C, 37 °C, 45 °C serta mampu tumbuh pada konsentrasi garam 4% dan 6,5%. Selanjutnya, 2 isolat BAL yang diisolasi pada waktu fermentasi 24 jam diuji lebih lanjut untuk dikembangkan sebagai kultur starter fermentasi biji kopi secara terkontrol. Kedua isolat BAL terpilih, yaitu BT24I1 dan BT24I2, diuji kemampuannya dalam menguraikan selulosa dan pektin. Hasil pengujian kualitatif menunjukkan kedua isolat BAL mampu menghasilkan selulase dan pektinase sehingga keduanya berpotensi dikembangkan sebagai kandidat kultur starter dalam fermentasi terkontrol biji kopi robusta dalam upaya pengembangan mutu dan cita rasa kopi                                                                 This study is an experimental study aimed at isolating lactic acid bacteria (BAL) indigenus involved in the spontaneous fermentation of robusta coffee beans from Bantaeng at fermentation time intervals of 0, 3, 6, 9, 24, 48, 72 hours and to find out the enzyme activity of the isolate of indigenus lactic acid bacteria as an effort to develop a starter culture in controlled coffee bean fermentation. The results showed that isolation was successfully carried out on 37 bacterial isolates involved in spontaneous fermentation of robusta coffee beans. The results of a simple identification carried out gradually showed only 12 bacterial isolates that were catalase negative, Gram positive, non spore, non-motile, non-gas-producing (homofermentative), growing at temperatures of 10 °C, 37 °C, 45 °C and able to grow at salt concentrations of 4% and 6.5%. Furthermore, 2 BAL isolates isolated at the fermentation time of 24 hours were further tested to be developed as a controlled coffee bean fermentation starter culture. The two selected BAL isolates, BT24I1 and BT24I2, tested their ability to decompose cellulose and pectin. Qualitative test results show that both BAL isolates can produce cellulase and pectinase so that both have the potential to be developed as candidates for starter cultures in controlled fermentation of robusta coffee beans in an effort to develop the quality and taste of coffee.

Abstract

The problem faced by the people of Semangki Village is that crop productivity is decreasing as a result of unnatural use of natural resources which is not supported by the expansion of reforestation, resulting in unproductive land conditions or critical land. The expansion of reforestation is not optimal due to lack of information and knowledge of the community in making efforts to minimize critical land. Through this activity, the public can obtain the widest possible information. The method used in carrying out this activity uses the lecture and question and answer method. The results of this activity showed the high enthusiasm of the community and increased knowledge after obtaining information on educational activities. The increase that occurred from the initial ability analysis data was obtained by 25% and the final ability was 85%.
